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

12 GB

Bandwidth

336 GB/s

Largest model

ERNIE-4.5-21B-A3B

RTX A3000 Mobile 12 GB carries 12 GB of GDDR6. That reaches comfortably into small and mid-sized models, though the largest stay out of reach without splitting them. Driver overhead leaves roughly 10.8 GB.

Memory bandwidth reaches 336 GB/s across a bus of 192 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.

The figure is the bus width multiplied by a memory clock of 1.75 GHz. Both halves matter, and neither is visible in a gaming benchmark.

In practice that combination tops out at ERNIE-4.5-21B-A3B, 21B, compressed to Q3_K_M and generating around 102 tokens per second.

The chip and how it was built

RTX A3000 Mobile 12 GB is built on the graphics processor GA104, using the architecture Ampere from NVIDIA, as part of the generation Ampere-MW(Ax000).

The chip is manufactured by Samsung, on a process of 8 nm, with a die measuring 392 mm², holding 17.4 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 March 2022, roughly 4.4815568035753 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

11.8 TFLOPS

FP64

184.3 GFLOPS

Tensor cores

128

On paper RTX A3000 Mobile 12 GB reaches 11.8 TFLOPS at half precision, and 11.8 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 reaches 184.3 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 128 tensor cores across 32 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 855 MHz to a boost of 1.44 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 A3000 Mobile 12 GB has an L1 cache of 128 KB, backed by an L2 cache of 4 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 4,096 shading units, 128 texture mapping units, and 64 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

115 W

RTX A3000 Mobile 12 GB is rated at 115 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.

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 A3000 Mobile 12 GB

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 411 models this card runs. Search narrows the list by name or by size.

  2. 02

    Set the context length you will actually use

    Longer conversations cost memory on top of the weights. Against 12 GB so the setting is worth getting right.

  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. The fastest result on this card is 142 tok/s on Gemma 3 QAT 1B. The same card and model vary by thirty to fifty per cent between inference runtimes.

  5. 05

    Check the headroom before you decide

    Tight means it works today; comfortable means it still works when the conversation grows. Compare what each model needs against an available 12 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 A3000 Mobile 12 GB.

Answers

RTX A3000 Mobile 12 GB — common questions

01

RTX A3000 Mobile 12 GB— what is the largest AI model it can run?

The largest model in our catalogue that fits is ERNIE-4.5-21B-A3B at 21B parameters, compressed to Q3_K_M. It generates roughly 102 tokens per second and needs about 10.1 GB of the card's memory.

02

RTX A3000 Mobile 12 GB— 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 142 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.

03

RTX A3000 Mobile 12 GB— 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 31.6 tokens per second.

04

RTX A3000 Mobile 12 GB— can it run 13B models?

Yes. For example it runs DeepSeekMoE-16B at Q4_K_M, using about 10.0 GB of memory and generating around 114 tokens per second.

05

RTX A3000 Mobile 12 GB— how much memory does it have?

This card has 12 GB of GDDR6. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 10.8 GB available for a model and its conversation.

06

RTX A3000 Mobile 12 GB— what is its memory bandwidth?

Memory bandwidth reaches 336 GB/s across a bus of 192 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.

07

RTX A3000 Mobile 12 GB— what type of memory does it use?

It uses GDDR6 clocked at 1.75 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.

08

RTX A3000 Mobile 12 GB— who makes it?

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

09

RTX A3000 Mobile 12 GB— when was it released?

It was released in March 2022.

10

RTX A3000 Mobile 12 GB— how much power does it use?

Rated board power is 115 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.

11

RTX A3000 Mobile 12 GB— how much cache does it have?

The L1 cache is 128 KB, and the L2 cache is 4 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.

12

RTX A3000 Mobile 12 GB— what are its TFLOPS?

It is rated at 11.8 TFLOPS at half precision and 11.8 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.

13

RTX A3000 Mobile 12 GB— how many tensor cores does it have?

It has 128 tensor cores across 32 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.

14

RTX A3000 Mobile 12 GB— 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.

15

RTX A3000 Mobile 12 GB— 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.

16

RTX A3000 Mobile 12 GB— is it good for running local AI models?

Its memory covers small and mid-sized models, though the largest are out of reach though its bandwidth means generation will feel slow on larger models. In total it runs 411 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

17

RTX A3000 Mobile 12 GB— can it run a model that does not fit in its memory?

Only partly. Layers beyond the card's 12 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.

18

Would two RTX A3000 Mobile 12 GB cards be twice as fast?

Pairing them buys headroom rather than pace: 24 GB to work with rather than twice the tokens per second — every figure here is for a single card.

19

RTX A3000 Mobile 12 GB— which AI models can it run?

411 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.

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.
