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.

What the numbers mean

Capacity and bandwidth

Memory

48 GB

Bandwidth

768 GB/s

Largest model

Qwen3-Coder-Next

RTX A6000 carries 48 GB of GDDR6. That covers the mid-sized models most people actually run. Once the runtime and driver reserve their working space, roughly this much is left: 43.2 GB.

Memory bandwidth reaches 768 GB/s across a bus of 384 bits. That is the number governing 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. Widening the bus and raising the clock are the two levers a manufacturer has, which is why a card with unremarkable cores can still generate quickly.

Put together, the largest model that fits is Qwen3-Coder-Next, 80B, compressed to IQ4_XS and generating around 55.5 tokens per second.

The chip and how it was built

RTX A6000 is built on the graphics processor GA102, using the architecture Ampere from NVIDIA, as part of the generation Workstation Ampere(Ax000).

The chip is manufactured by Samsung, on a process of 8 nm, 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 5.9416146396284 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 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 reaches 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 a base of 1.41 GHz to a boost of 1.8 GHz. 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

RTX A6000 has an L1 cache of 128 KB, backed by an L2 cache of 6 MB. 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

RTX A6000 is rated at 300 W, and the suggested system power supply is 700 W. 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 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.

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.

  1. 01

    Start with the model, not the specification

    The table lists 607 models this card can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.

  2. 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 against a card holding 48 GB that is frequently the difference between a model fitting and not.

  3. 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.

  4. 04

    Take the range as the answer

    The figures are calculated, not measured. The fastest result on this card is 325 tok/s on Gemma 3 QAT 1B. The same card and model vary by thirty to fifty per cent between inference runtimes.

  5. 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 an available 48 GB.

  6. 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 right buy is RTX A6000.

Answers

RTX A6000 — common questions

01

RTX A6000— how many tokens per second does it produce?

It depends on the model. The fastest model we track here 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.

02

RTX A6000— can it run 7B models?

Yes. For example it runs Gemma 4 E4B at Q8_0, using about 9.8 GB of memory and generating around 72.3 tokens per second.

03

RTX A6000— can it run 13B models?

Yes. For example it runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 113 tokens per second.

04

RTX A6000— can it run 30B models?

Yes. For example it 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.

05

RTX A6000— can it run 70B models?

Yes. For example it runs Qwen3-Coder-Next at IQ4_XS, using about 38.8 GB of memory and generating around 55.5 tokens per second.

06

RTX A6000— how much memory does it have?

This card has 48 GB of GDDR6. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 43.2 GB available for a model and its conversation.

07

RTX A6000— what is its memory bandwidth?

Memory bandwidth reaches 768 GB/s across a bus of 384 bits. 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.

08

RTX A6000— what type of memory does it 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.

09

RTX A6000— who makes it?

This is a product of NVIDIA, with the chip manufactured by Samsung, on a process of 8 nm.

10

RTX A6000— when was it released?

It was released in October 2020.

11

RTX A6000— how much power does it use?

Rated board power is 300 W, and the suggested system power supply is 700 W. Generating text draws hard in bursts and idles between requests, so average consumption over a working session is normally well below the rated figure.

12

RTX A6000— how much cache does it have?

The L1 cache is 128 KB, and the L2 cache is 6 MB. 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.

13

RTX A6000— what are its TFLOPS?

It 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.

14

RTX A6000— how many tensor cores does it have?

It 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.

15

RTX A6000— does it support CUDA?

Yes. It 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.

16

RTX A6000— what bus interface does it 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.

17

RTX A6000— is it 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 607 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

18

RTX A6000— can it run a model that does not fit in its memory?

Only partly. Layers beyond the card's 48 GB drags the whole thing down, and none of the figures on this page assume it.

19

Would two RTX A6000 cards be twice as fast?

Pairing them buys headroom rather than pace: 96 GB which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.

20

RTX A6000— which AI models can it run?

607 of the 721 open-weight language models we track fit on this card and can be run locally. The table on this page lists every one, with the memory it needs, the quantisation it runs at and an estimated generation speed.

21

RTX A6000— what is the largest AI model it can run?

The largest model in our catalogue that fits 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.

The other direction

Looking at it from the other side?

This page starts from the hardware. If you already know which model you want and need to know what it takes to run it, start from the model instead.
