LLM Benchmark Results:Every Configuration Measured on Our Own GPUs

Direct answer The best private LLM depends on the hardware tier, and every result below was measured on GPUs Petronella Technology Group, Inc. owns, never copied from a vendor. One GB10 appliance runs Nemotron-3.5-Lightning at 90 tok/s for a single user and 795 tok/s across 64 users. A four-unit GB10 pod runs Qwen3.8-Flash-Next at 649 tok/s across 64 users, or GLM-5.3-Flash when quality matters more. A DGX Station GB300 runs GLM-5.3-Flash with a verified 968,000-token needle at 145 tok/s for one user, the same single-user speed as four H200s. The H200 quad stays the concurrency leader at 5,245 tok/s across 256 users. Browse the result cards, the platform tier list and the full leaderboard tables.

These LLM benchmarks are organized the way we actually use the results: one card per model and hardware configuration, with the engine, the quantization, the context, the single-user and concurrent throughput, the measured date and the trade-offs in the open. Where a community recipe or engine produced a result, the card says so. Where we did not measure something, the card says that too.

What These LLM Benchmarks Measure and Why It Matters

These LLM benchmarks measure how well a model does the work a regulated firm needs done, on hardware that firm can own, rather than how it scores on a public test set it may have been trained on. Public leaderboards rank models on academic corpora and often republish vendor numbers. A buyer who needs a model to fix a production script, answer a compliance question with a citation, or refuse an unsafe tool call gets little from a single aggregate score.

So Petronella Technology Group, Inc. built its own harness and ran it on its own fleet: eight NVIDIA GB10 appliances (four DGX Spark, four MSI EdgeXpert) on a switched 200G RoCE fabric, one DGX Station GB300, RTX PRO 6000 Blackwell workstation cards and a four-way H200 NVLink pool. Each configuration runs a fixed battery: tool-calling suites, agentic multi-turn tasks, a closed-book and a retrieval-grounded compliance set, coding, long-form writing and long-context needle tests, all cross-judged so no model is ever graded by a model from its own family. The rules behind that battery, and the conclusions we have retracted after auditing our own work, are on the benchmark methodology page.

Three rules make a card on this page trustworthy. First, every speed number is gated: an engine must pass arithmetic and needle-in-a-haystack checks before any throughput is recorded. Second, every number carries its serving configuration, because the wrong tool parser or a missing speculative-decoding flag changes a result more than a model swap does. Third, every card names the date it was measured and the stored result file it came from, so the age of every row is visible.

Why it matters: the models that win here are the models you can run inside your own compliance boundary. Coding and cited research on CUI, PHI or privileged material cannot be sent to a third-party API, so the practical question is not which model is best in the abstract but which configuration is best on the hardware tier you can justify. That is what the cards, the tier list and the cost table below answer.

Result cards

Every Configuration We measured, One Card Each

Each card is one model on one hardware configuration with the engine and quantization that produced the number: single-user and concurrent decode, prefill, context, the measured date and the trade-offs. Cards marked with a recipe credit ran a community-published engine or launch recipe; the credit section below names each one. Full ladders and the quality battery are on the leaderboards page.

Weaknesses: the most expensive tier: about $121,000 for the four cards at a July 2026 market average, which is not an MSRP, and the true cost is higher with the host server. No FP4 path (sm_90). Slower prefill per request than the GB300. It is shared production, so it can be benchmarked only in quiet windows.

Strengths: the same model the four-appliance pod runs, three to five times faster per stream, because the workstation cards have roughly six times the memory bandwidth. It also outscores the dense 27B on coding and cited research, so this tier costs nothing in quality. Weaknesses: no published per-watt figure (the chassis is not on a metered outlet), prefill was not measured in this run, and four PCIe cards need the chipset lanes a workstation provides.

Cards without a measured value in a field say so rather than estimate. Configurations we measured but do not card (three-unit and six-unit layouts, the DeepSeek-V4.1-Flash TensorFold test, the GLM-5.3 full offload run) are on the leaderboards page with their sources.

Tier list

Platform Tier List: Which Configuration Is Worth Building

These tiers rank hardware configurations, not models, by measured value for a regulated private deployment: throughput per $1,000 at matched operating points, tokens per joule, the quality ceiling the configuration reached, and the data class or context depth it unlocks. A configuration can appear twice when two layouts of the same hardware behave differently. Every figure repeats a measured number from the cards and the leaderboards.

How to read the tiers (S is the best value we measured, C the weakest):

S tier: Deploy this first. The pick we would build or run first at this budget.
A tier: Strong, with a trade-off. A good choice once you understand what it gives up.
B tier: Right for a niche. Good for a specific need, wrong as a default.
C tier: Measured, but beaten. Something cheaper or simpler does the same job better.
S

One GB10 appliance · the individual and small-team tier

Why S: the best affordability on the page. Nemotron-3.5-Lightning NVFP4 delivers 19.2 tok/s per $1,000 for a single user and 169 at its 64-user ceiling on a $4,699 list-price appliance, at 6.3 tok/J, and one unit served a full million tokens of context. For prefill-heavy work (retrieval, summarization, classification) one GB10 is a 4,600 to 6,900 tok/s machine.

The catch: pick the model for the work. Nemotron's quality is the weakest measured (29 of 38 tools, 3 of 35 closed-book compliance); Gemma-4-26B-A4B holds real quality (37 tools, 13 to 14 compliance, 24 of 26 long context) at 31 tok/s for one user, and grounded retrieval lifts it to 55 to 62 of 93 strict.

S

Four GB10 units on the 200G RoCE fabric · the production pod tier

Why S: the best combination of throughput, efficiency and quality on one budget. Qwen3.8-Flash-Next serves 617 to 649 tok/s across 64 users at 1.18 tok/J (34.5 tok/s per $1,000 at the ceiling); GLM-5.3-Flash on the same four units holds the best closed-book compliance of any GB10 layout (26 of 35) with zero hallucinated tool calls and a million-token context with a 3.9M KV pool.

The catch: the fabric is not optional (direct cables made a four-way cluster slower than one unit), and the two models trade speed for quality, so the pod runs whichever the workload needs.

A

Two GB10 units · the long-context pair

Why A: a pair buys depth, not speed. DeepSeek-V4-Flash-Vision-Exp on two units is the best two-unit single-user model measured (47.8 tok/s prose, tools 38, long context 26 of 26) and serves a million tokens. Qwen3.8-Flash-Next on a pair is the serving option: 329.6 tok/s across 32 users at 1.16 tok/J.

The catch: the Vision-Exp kit caps at 6 sequences (117 tok/s ceiling) and is the least efficient measured layout at 0.41 tok/J; one 26B-A4B unit already serves 64 users at the floor, so a pair is rarely worth it for throughput alone.

A

DGX Station GB300 · the single-box frontier tier

Why A: one user at 145 tok/s matches four H200s, with the largest verified context in the fleet (a 968,377-token needle found) and 32.9k tok/s prefill, all in one box with no fabric. The strongest closed-book compliance of the one-box candidates (26 of 35, the only correct SSP narrative among them).

The catch: it must run 4-bit (the FP8 checkpoint does not fit 252 GB), which measurably loses exact compliance recall (121 vs 138 of 175 over five runs); aggregate plateaus at 1.7 to 2.2k tok/s from 32 users up; and NVIDIA has published no MSRP, so its affordability row rests on the reported launch price, not a list price.

B

Four H200 NVLink · the concurrency tier

Why B, not S: nothing we measured serves more simultaneous users (5,245 tok/s at 256 users, still scaling at 128), runs FP8 natively with the best measured compliance mean (27.6 of 35), or carries frontier-size open models whole. But it is the most expensive tier (about $121,000 for the cards at a July 2026 market average, not an MSRP, plus the host server), it has no FP4 path, and its per-watt figure is not measured because the pool is not on metered outlets. For a single user it buys nothing over the GB300.

B

Eight GB10 units as two four-unit groups · the scaled pod

Why B: the same eight units, split into two independently measured four-unit groups, add up to about 1,266 to 1,298 tok/s across 128 users against 770 for one eight-way engine. Those totals are arithmetic from the measured group rows at matched load, not one concurrent test (the groups sit on separate switches, and earlier concurrent runs showed no cross-group interference, but we have not re-run both groups at once since the October 3 circuit trip).

C

Eight GB10 units as one eight-way engine · only for single-user speed

Why C: the worst value per dollar on the page for anything but one user at a time: 20.5 tok/s per $1,000 at 64 users (770 tok/s) against 34.5 for each four-unit group. An eight-way group pays communication overhead across the whole fabric on every token while two four-way groups stay local and take separate queues. Its one win is single-user speed, 45.7 tok/s. Build this layout only when one user must have the whole pod.

Affordability: Throughput per Dollar and per Joule, With the Price Basis Stated

Affordability is part of the honest picture, so it is measured, not implied. Prices are list prices where a manufacturer publishes one and clearly labeled market figures where it does not. GPU prices vary with market conditions; treat every per-dollar row as a snapshot of the stated basis, not a quote.

Throughput per $1,000 of hardware, prose decode, at matched operating points. Price basis stated per row. Measured October 2 to 3, 2026 (GB10 rows) and September 25, 2026 (GB300 and H200 rows). Source files: 2026-10-02-best-model-per-tier-results.md sections 1, 3, 4.3; 2026-09-25-dgx1-best-model-eval.md section 4.3.

What the price rows hide, stated plainly. Four of the eight clustered GB10 units are MSI EdgeXpert systems, priced here at the DGX Spark list price because MSI has published no price of its own. Fabric is excluded from the cluster rows: a pair needs one cable, four and eight units need a switch and breakout cables, so the cluster rows are, if anything, flattered by the exclusion. The DGX Station has no published MSRP at all, so its row uses the reported launch price and is labeled as such. The H200 row excludes the host server the cards live in. NVIDIA's DGX Spark list price has held at $4,699 since February 2026; card and appliance prices move with market conditions, so re-check the basis before using any row in a purchase decision.

The efficiency spread is large and it is mostly architecture: the one-unit MoE models turn wall power into tokens about 75 times better than the eight-unit MiMo layout (6.30 against 0.083 tok/J), because bandwidth-bound appliances with few active parameters are the efficient point of this fleet and a 535 GB eight-way model is not. On the MSI units, letting the clocks boost to default raised wall power 10 to 23 percent and cut tokens per joule 12 to 18 percent on the multi-user tests while changing throughput by about 1 percent, which is why the locked-clock rows are the ones we serve.

Which tier you can justify depends on the memory pool your target model needs, the number of concurrent users at peak and the data class you handle. Our on-premise AI server builds page covers the platforms behind each tier, and the self-hosted LLM planning guide covers the decisions that come before hardware.

Aggregate prose decode tok/s by concurrent users. "Peak" is the largest user count measured. GB10 rows measured October 2 to 3, 2026 at a locked 2,300 MHz; GB300 and H200 rows September 25, 2026. Where a configuration's battery used a different workload or user ladder, the cell says so.

The two ladders tell opposite stories, and both matter when sizing a deployment. Prefill is compute-bound and it is where the GB300 is untouchable: 32.9k tok/s at an 8k prompt is about nine times the four-unit GB10 pod. Decode is bandwidth-bound and it is where the appliance pod earns its keep per dollar. A retrieval workload (long prompt, short answer) and a drafting workload (short prompt, long answer) can land on different platforms, which is exactly why both ladders are published.

Verification

Checked, Not Assumed: What Stands Behind Every Number

A number earns a card only after the checks below. Where a check failed or stayed inconclusive, we publish that too, because a failed check is information a buyer needs.

Before any speed number

A correctness gate runs first, and a failed gate blocks the row.

Every engine starts from a fresh reboot of its units with a 20-second burn verify (no 611 MHz clock latch was seen on any unit in any run). Before any throughput is recorded, the engine must pass arithmetic and needle-in-a-haystack checks to 120k tokens; the GB10 tier runs passed the gate 8 of 8 in both clock states. A wall-power meter (rack PDU, per unit) and one-second GPU telemetry are recorded during each run.

Context claims

Advertised context is not served context, so every context row is needle-verified.

The DGX Station found a needle in a 968,377-token prompt at 10, 50 and 90 percent depth (33 to 37 s each). Nemotron-3.5-Lightning served a full 1,048,576 tokens but its 983,609-token needle produced no verbatim answer within the 4,096-token budget, so we call that row "served, not needle-verified". The two-unit GLM engine accepted 655,360 tokens (a 786,432 setting was OOM-killed by the kernel), but a roughly 589k-token prompt killed the engine on an executor timeout, so the pair is honestly a 262k, 6-request GLM until the timeout knob is re-tested. We publish the failure because it is the difference between what an engine accepts and what it completes.

Same-hardware checks

Same-clock parity runs catch hardware drift before it contaminates a comparison.

At an equal 2,300 MHz clock the DGX Spark and MSI EdgeXpert builds decoded within 2 percent on every one-unit and two-unit point (the MSI drew 4 to 8 W more per unit and ran 1 to 8 C warmer). Locked-clock versus default-boost changed multi-user throughput by about 1 percent while raising wall power 10 to 23 percent. Zero power-loss events and zero clock latches were recorded across both states.

Quality claims

No model is ever graded by a model from its own family.

Self-judging inflates scores 20 to 37 percent in our measurements, so every quality row is cross-judged: the generator never shares a family with the judge, headline studies use a three-model frontier panel with the median taken per case, and longitudinal rows use a locked campaign judge with the temperature and rep count stamped on each. The methodology page documents the judge lock, the metadata every result file must carry, and the four conclusions we retracted after auditing our own staged claims.

Recipe credits

Standing on Community Recipes, Named Where Used

Several results on this page run a community-published engine, checkpoint or launch recipe. The credit belongs on the card, so here is the complete list of which result used whose work. Everything else on the page ran NVIDIA's own published recipes or our own launch configurations.

  • Mia (Mia's AI Lab): the two-unit DeepSeek-V4-Flash-Vision-Exp card ran her Anemll DGX Spark kit, and the DeepSeek-V4-Flash-0731 forum lanes ran the AlexLJC/MiaAI kit. Her published work at github.com/MiaAI-Lab.
  • TensorFold, by Ash Hart: the DeepSeek-V4.1-Flash-1017 two-unit and four-unit tests (October 18 to 19) ran Tony's TensorFold builds of the LibertAI EXL3 checkpoints. The engine is at github.com/ashhart/TensorFold.
  • BertholomusAI: the September 25 lane comparing DeepSeek-V4-Flash-0731 at TP4 against two TP2 pairs ran BertholomusAI's recipe.
  • tonyd2wild: the GLM-5.3-Flash GB10 results run his v11 vLLM build with the DFlash2 block drafter.
  • oxbyte: the Qwen3.8-Flash-Next pod results use his MTP4 and expert-parallel serving configuration.
  • rhys101: the MiMo-V2.6-Pro-RL card runs his SGLang a14 recipe with the DFlash-8 adaptive drafter.
  • NVIDIA: the one-unit Nemotron, Qwen3.6 and Gemma cards run NVIDIA's published DGX Spark recipes and NVFP4 checkpoints.

Where our numbers differ from a recipe's published numbers, both are stated (the MiMo card reproduces its published speed within 5 percent; the TensorFold DeepSeek run measured about 8 percent under its published single-stream figure). A recipe credit means the launch configuration came from the community author; every measurement, quality score and verdict on this page is ours.

FAQ

LLM Benchmarks FAQ

Short answers to the questions buyers ask most; every figure repeats a result shown above.

What do these benchmarks actually measure?
Each configuration runs a fixed battery: tool-calling suites (38 tasks plus a 27-case multi-turn corpus), agentic multi-turn tasks, a closed-book and a retrieval-grounded compliance set, coding, long-form writing against a 10-criteria rubric, and long-context needle tests. Speed is measured as steady closed-loop decode at 1 to 64 users (three repetitions, 512-token answers, temperature 0, prose and code separately) and as prefill at 8k, 32k and 128k prompts with the prefix cache defeated. A correctness gate must pass before any speed number is recorded.
Can a model grade its own output?
No. Self-judging inflates scores 20 to 37 percent in our measurements, so the generator never shares a model family with the judge. Headline studies use a three-model frontier panel (GPT-5.4, Claude Opus and DeepSeek class judges) with the median per case; longitudinal rows use a locked campaign judge so a row from one month stays comparable to a row from the next.
What hardware were these results measured on?
The fleet Petronella Technology Group, Inc. operates itself: eight NVIDIA GB10 appliances (four DGX Spark, four MSI EdgeXpert) on a switched 200G RoCE fabric, one DGX Station GB300, RTX PRO 6000 Blackwell workstation cards and a four-way H200 NVLink pool. Every GB10 speed row was measured with all units locked at 2,300 MHz unless the row says otherwise, and the clock state is recorded on every row.
Does adding units make a single user faster?
Rarely, and never proportionally. On the pod, Qwen3.8-Flash-Next single-user speed moved from 41.4 to 45.7 tok/s going from four units to eight as one engine, while the eight-way engine's value per dollar fell to 20.5 tok/s per $1,000 at 64 users against 34.5 for each four-unit group. Units buy model size, context and concurrent users, not single-user speed. The DGX Station is the exception that behaves like a bigger single box.
Why do some cells say "not measured"?
Because we did not measure it, and an empty cell is more useful than an estimate. The DGX Station and the H200 pool are not on metered outlets, so their tokens-per-joule cells are blank. The RTX PRO 6000 chassis prefill was not part of that run. The two four-unit groups have not been re-run concurrently since the October 3 circuit trip, so their combined total is labeled as projected arithmetic from separately measured groups.
How are prices handled?
With the basis stated on every row. The DGX Spark is priced at NVIDIA's $4,699 list price (hardware only, unchanged since February 2026); the four MSI EdgeXpert units are priced at that same list price because MSI has published none of its own. The DGX Station has no published MSRP, so its row uses the reported launch price and is labeled as such. The H200 row uses a July 2026 market average of about $30,316 per card, which is not an MSRP. GPU prices vary with market conditions; every per-dollar figure is a snapshot of its stated basis, not a quote.
Which model should run for compliance work?
Closed-book, GLM-5.3-Flash leads everywhere we ran it (26 of 35 on the GB300 and the four-unit pod; the FP8 checkpoint on the H200 pool averages 27.6). The small MoE models are far behind closed-book (Gemma-4 at 13 to 14, Qwen3.8-Flash-Next at 13.8, Nemotron at 3), but grounded retrieval changes the picture: with passages from the public NIST and DoD corpus supplied, every model tested reached 77 to 91 strict on the 93-question battery and fabrications fell to zero to three. Retrieval quality matters more than model size.
Is 4-bit quantization safe for compliance answers?
It depends on the checkpoint and the task. NVIDIA's NVFP4 GLM-5.3-Flash scored 128 of 175 compliance items over five runs against 138 for FP8, a real but modest loss concentrated on exact recall; the RedHatAI 4-bit build lost more (121 of 175). Feeding the NIST text with retrieval closed the gap entirely (both variants 26 of 26 on document-grounded tasks), so for compliance work the practical rule is 4-bit plus retrieval, or FP8 where the memory allows.
Why does a card name a recipe author?
Because serving configurations are first-class variables and provenance is part of the number. Several results ran community-published engines or launch recipes (named in the credits section): the engine, drafter and parallelism settings change throughput and sometimes quality more than a model swap does. A recipe credit covers the launch configuration only; every measurement, quality score and verdict on this page is ours.
Can Petronella Technology Group, Inc. run one of these configurations inside my compliance boundary?
Yes. We design, build and operate private AI on hardware you own, from a single GB10 appliance to a multi-H200 deployment, for firms that handle CUI, PHI or privileged data, and every configuration carded on this page is one we run or have run ourselves.
