Speeds are estimates for a single request — one conversation at a time — calculated from memory bandwidth, model size and quantisation. Real throughput varies with the inference runtime and its version. Figures published by hardware vendors measure many simultaneous requests and are much higher.

Largest model
Qwen3-Coder-Next
The RTX A6000 carries 48 GB of GDDR6, which covers the mid-sized models most people actually run — about 43.2 GB of it after the runtime and driver reserve their working space.
The memory bus moves 768 GB/s across a 384-bit bus. That is the number that governs generation speed — arithmetic per byte read is small enough that the bus, not the cores, is what everything waits on.
Bandwidth is clock times bus width, and this card clocks its memory at 2 GHz. Both halves matter, and neither is visible in a gaming benchmark.
Put together, the largest model that fits is Qwen3-Coder-Next at 80B, running IQ4_XS and producing around 55.5 tokens per second.
The chip and how it was built
The RTX A6000 is built on the GA102 graphics processor, using NVIDIA's Ampere architecture, as part of the Workstation Ampere(Ax000) generation.
The chip is manufactured by Samsung, on a 8 nm process, with a die measuring 628 mm², holding 28.3 billion transistors. A smaller process generally means more performance for the same power, though for language models it matters far less than the memory subsystem.
It was released in October 2020, roughly 5 years ago. Inference software support tends to follow hardware by a year or two, so a card of this age generally has mature, well-optimised code paths available to it.
Compute throughput, and why it matters less than it looks
FP16
38.7 TFLOPS
FP64
604.8 GFLOPS
Tensor cores
336
On paper the RTX A6000 reaches 38.7 TFLOPS at half precision and 38.7 TFLOPS at single precision. These are peak figures no real workload sustains, and generating text reaches only a small fraction of them — decoding is limited by memory rather than arithmetic, which is why a card can look enormously powerful here and still produce tokens at an ordinary rate.
Double-precision throughput is 604.8 GFLOPS. It has no bearing on running a language model — no inference runtime uses it — but it separates datacentre parts from consumer ones, since the latter deliberately restrict it.
The card carries 336 tensor cores across 84 streaming multiprocessors. These accelerate the matrix arithmetic at the heart of a transformer, and they are what make prompt processing — reading a long document before answering — dramatically faster than it would otherwise be.
Clocks run from 1.41 GHz at base to 1.8 GHz boosted. Worth far less here than on a gaming benchmark: raising the clock speeds up the arithmetic, and the arithmetic is not what generation is waiting on.
Cache and processing units
The RTX A6000 has 128 KB of L1 cache, backed by 6 MB of L2. Cache absorbs a share of the memory traffic that would otherwise hit the main bus, which is the one place on this page where a number other than bandwidth quietly affects generation speed — a large L2 lets more of the working set stay close to the cores.
There are 10,752 shading units, 336 texture mapping units, and 112 render output units. These drive graphics workloads and contribute to prompt processing, but they sit idle for much of the time a model spends generating a reply.
Power, size and installation
Power draw
300 W
The RTX A6000 is rated at 300 W, with a 700 W power supply suggested for the whole system. Running a language model keeps a card busy in bursts rather than continuously — it draws hard while generating and idles between requests — so sustained draw over a working day is usually well below the rated figure.
The board occupies a dual-slot, measuring 267 mm long, and needs 8-pin EPS. Worth checking against the case and power supply already in the machine, since the largest cards need considerably more of both than a typical desktop provides.
It connects over PCIe 4.0 x16. The interface governs how quickly a model is loaded from disk into the card, not how fast it runs once there, so a narrower link costs a few seconds at startup and nothing thereafter.
The extremes

The biggest open-weight models that fit on this card, newest first. Each is shown at the best compression the card can hold.
The fastest AI models on a RTX A6000
Where this card produces tokens quickest. Smaller models dominate here, because generating each token means reading the whole model out of memory once.
Step by step
How to work out the tokens per second of a RTX A6000
You do not have to calculate anything by hand — the gputps.com calculator on this page has already worked it out for every model this card can hold. Reading off the answer takes six steps.
-
01
Start with the model, not the specification
The table lists 576 models this RTX A6000 can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Decide how long your conversations run
Drag the slider to the conversation length you plan to work at. The cache grows with the conversation, and on 48 GB it is often what pushes a large model over the edge.
-
03
Set a minimum quality if you need one
Each model is shown at the best compression this card can hold. A minimum quality hides the ones that only fit by being squeezed further than you would accept.
-
04
Take the range as the answer
The figures are calculated, not measured. 325 tok/s on Gemma 3 QAT 1B is the fastest result on this card, and like every row it carries a range that reflects how much the runtime matters.
-
05
Read the fit verdict last
A tight fit runs but leaves no room to raise the context later; comfortable has headroom. The memory column shows what each model needs against the 48 GB available.
-
06
Open the model to compare cards
Every model name in the table links to its own page, which runs the same calculation across every card we hold. That is where you see whether the RTX A6000 is the right buy for it or merely a card that fits.
Answers
RTX A6000 — common questions
How many tokens per second does a RTX A6000 produce?
It depends on the model. On a RTX A6000 the fastest model we track is Gemma 3 QAT 1B at about 325 tokens per second, while larger models run proportionally slower because each token requires reading the whole model out of memory once. Speeds are estimates for a single conversation at a time.
Can a RTX A6000 run a 7B model?
Yes. For example a RTX A6000 runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 48.6 tokens per second.
Can a RTX A6000 run a 13B model?
Yes. For example a RTX A6000 runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 113 tokens per second.
Can a RTX A6000 run a 30B model?
Yes. For example a RTX A6000 runs ERNIE-4.5-VL-28B-A3B at Q8_0, using about 29.2 GB of memory and generating around 64.5 tokens per second.
Can a RTX A6000 run a 70B model?
Yes. For example a RTX A6000 runs Qwen3-Coder-Next at IQ4_XS, using about 38.8 GB of memory and generating around 55.5 tokens per second.
How much memory does a RTX A6000 have?
A RTX A6000 has 48 GB of GDDR6 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 43.2 GB available for a model and its conversation.
What is the memory bandwidth of a RTX A6000?
The RTX A6000 has 768 GB/s of memory bandwidth, across a 384-bit memory bus. This is the single best predictor of how fast it generates text, because producing each token means reading the entire model out of memory once.
What type of memory does a RTX A6000 use?
It uses GDDR6 clocked at 2 GHz. HBM types are found on datacentre accelerators and carry far more bandwidth than the GDDR used on desktop cards, which is why they generate tokens considerably faster at the same capacity.
Who makes the RTX A6000?
The RTX A6000 is a NVIDIA product, with the chip manufactured by Samsung, on a 8 nm process.
When was the RTX A6000 released?
The RTX A6000 was released in October 2020.
How much power does a RTX A6000 use?
The RTX A6000 has a rated board power of 300 W, and a 700 W system power supply is suggested. Generating text draws hard in bursts and idles between requests, so average consumption over a working session is normally well below the rated figure.
How much cache does a RTX A6000 have?
The RTX A6000 has 128 KB of L1 cache, and 6 MB of L2 cache. Cache absorbs part of the memory traffic that would otherwise reach the main bus, so a larger L2 gives a modest lift to generation speed beyond what bandwidth alone predicts.
What are the TFLOPS of a RTX A6000?
The RTX A6000 is rated at 38.7 TFLOPS at half precision and 38.7 TFLOPS at single precision. These are peak arithmetic ceilings rather than achievable rates, and text generation reaches only a small fraction of them because it is limited by memory bandwidth instead.
How many tensor cores does a RTX A6000 have?
The RTX A6000 has 336 tensor cores across 84 streaming multiprocessors. They accelerate the matrix arithmetic a transformer is built from, which mainly speeds up processing a long prompt rather than producing the reply.
Does the RTX A6000 support CUDA?
Yes. The RTX A6000 reports CUDA compute capability 8.6. Capability 7.0 and above has tensor cores, which modern inference software uses; below that it falls back to slower code paths for quantised models.
What bus interface does the RTX A6000 use?
It uses PCIe 4.0 x16. This governs how fast a model is loaded onto the card rather than how fast it runs once loaded, so it costs a few seconds at startup and nothing during generation.
Is the RTX A6000 good for running local AI models?
Its memory is large enough for models most desktop hardware cannot touch and its bandwidth gives usable, if unspectacular, generation speeds. In total it runs 576 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a RTX A6000 run a model that does not fit in its memory?
Only partly. Layers beyond the 48 GB sit in system memory and run at a fraction of the speed, so a mostly-offloaded model is rarely worth using. Every figure here assumes it is fully resident on the card.
Would two RTX A6000 cards be twice as fast?
Pairing RTX A6000 cards buys headroom rather than pace: 96 GB of combined memory, at roughly the same generation speed as one.
What AI models can a RTX A6000 run?
576 of the 679 open-weight language models we track fit on a RTX A6000 and can be run locally on it. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.
What is the largest AI model a RTX A6000 can run?
The largest model in our catalogue that fits on a RTX A6000 is Qwen3-Coder-Next at 80B parameters, compressed to IQ4_XS. It generates roughly 55.5 tokens per second and needs about 38.8 GB of the card's memory.
