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

What the memory subsystem means for AI

Memory

12 GB

Bandwidth

768 GB/s

Largest model

ERNIE-4.5-21B-A3B

12 GB of GDDR6 puts the RTX A5000-12Q comfortably into small and mid-sized models, with roughly 10.8 GB usable once the driver overhead is taken out. The largest models are out of reach without splitting them.

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.

The biggest thing it holds is ERNIE-4.5-21B-A3B (21B) at Q3_K_M compression, for about 232 tokens per second.

The chip and how it was built

The RTX A5000-12Q 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 April 2021, 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

27.8 TFLOPS

FP64

433.9 GFLOPS

Tensor cores

256

On paper the RTX A5000-12Q reaches 27.8 TFLOPS at half precision and 27.8 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 433.9 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 256 tensor cores across 64 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 1.17 GHz at base to 1.7 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 A5000-12Q 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 8,192 shading units, 256 texture mapping units, and 96 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

230 W

The RTX A5000-12Q is rated at 230 W, with a 550 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 1x 8-pin. 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 A5000-12Q

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

    Find the model in the table

    The table lists 396 models this RTX A5000-12Q can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.

  2. 02

    Match the context to your work

    Longer conversations cost memory on top of the weights. With 12 GB to work in, that is frequently the difference between a model fitting and not.

  3. 03

    Pin the comparison to one quality level

    By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.

  4. 04

    Look at the range, not just the number

    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.

  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 the 12 GB available.

  6. 06

    Cross-check against other hardware

    Following a model through to its own page lists all the hardware that can run it, so you can see where the RTX A5000-12Q sits against the alternatives.

Answers

RTX A5000-12Q — common questions

01

Does the RTX A5000-12Q support CUDA?

Yes. The RTX A5000-12Q 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.

02

What bus interface does the RTX A5000-12Q 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.

03

Is the RTX A5000-12Q good for running local AI models?

Its memory covers small and mid-sized models, though the largest are out of reach and its bandwidth gives usable, if unspectacular, generation speeds. In total it runs 396 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

04

Can a RTX A5000-12Q run a model that does not fit in its memory?

It can be split, with the overflow held in system memory — but that part drags the whole thing down, and none of the 12 GB figures on this page assume it.

05

Would two RTX A5000-12Q cards be twice as fast?

Capacity adds, throughput does not. Two of them give you 24 GB to work with rather than twice the tokens per second — every figure here is for a single RTX A5000-12Q.

06

What AI models can a RTX A5000-12Q run?

396 of the 679 open-weight language models we track fit on a RTX A5000-12Q 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.

07

What is the largest AI model a RTX A5000-12Q can run?

The largest model in our catalogue that fits on a RTX A5000-12Q is ERNIE-4.5-21B-A3B at 21B parameters, compressed to Q3_K_M. It generates roughly 232 tokens per second and needs about 10.1 GB of the card's memory.

08

How many tokens per second does a RTX A5000-12Q produce?

It depends on the model. On a RTX A5000-12Q 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.

09

Can a RTX A5000-12Q run a 7B model?

Yes. For example a RTX A5000-12Q runs DeepSeek Coder 6.7B at Q6_K, using about 9.9 GB of memory and generating around 70.5 tokens per second.

10

Can a RTX A5000-12Q run a 13B model?

Yes. For example a RTX A5000-12Q runs DeepSeekMoE-16B at Q4_K_M, using about 10.0 GB of memory and generating around 261 tokens per second.

11

How much memory does a RTX A5000-12Q have?

A RTX A5000-12Q has 12 GB of GDDR6 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 10.8 GB available for a model and its conversation.

12

What is the memory bandwidth of a RTX A5000-12Q?

The RTX A5000-12Q 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.

13

What type of memory does a RTX A5000-12Q 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.

14

Who makes the RTX A5000-12Q?

The RTX A5000-12Q is a NVIDIA product, with the chip manufactured by Samsung, on a 8 nm process.

15

When was the RTX A5000-12Q released?

The RTX A5000-12Q was released in April 2021.

16

How much power does a RTX A5000-12Q use?

The RTX A5000-12Q has a rated board power of 230 W, and a 550 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.

17

How much cache does a RTX A5000-12Q have?

The RTX A5000-12Q 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.

18

What are the TFLOPS of a RTX A5000-12Q?

The RTX A5000-12Q is rated at 27.8 TFLOPS at half precision and 27.8 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.

19

How many tensor cores does a RTX A5000-12Q have?

The RTX A5000-12Q has 256 tensor cores across 64 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.
