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

Memory: the specification that decides everything

Memory

16 GB

Bandwidth

484 GB/s

Largest model

Nemotron 3-Nano-30B-A3B

Radeon Pro V340 16 GB carries 16 GB of HBM2. That reaches comfortably into small and mid-sized models, though the largest stay out of reach without splitting them. Driver overhead leaves roughly 14.4 GB.

Memory bandwidth reaches 484 GB/s across a bus of 2,048 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 945 MHz. It is why core counts predict generation speed so poorly.

The practical ceiling is Nemotron 3-Nano-30B-A3B, 31.6B, compressed to Q3_K_M and generating around 75.8 tokens per second.

The chip and how it was built

Radeon Pro V340 16 GB is built on the graphics processor Vega 10, using the architecture GCN 5.0 from AMD, as part of the generation Radeon Pro Vega(Vega Series).

The chip is manufactured by GlobalFoundries, on a process of 14 nm, with a die measuring 495 mm², holding 12.5 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 August 2018, roughly 7.9313551342715 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

21.5 TFLOPS

FP64

672 GFLOPS

On paper Radeon Pro V340 16 GB reaches 21.5 TFLOPS at half precision, and 10.8 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 672 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.

Clocks run from a base of 852 MHz to a boost of 1.5 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

Radeon Pro V340 16 GB has an L1 cache of 16 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 3,584 shading units, 224 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

230 W

Radeon Pro V340 16 GB is rated at 230 W, and the suggested system power supply is 550 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 2x 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 3.0 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 Radeon Pro V340 16 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

    Search for the model you want

    The table lists 432 models this card runs. Search narrows the list by name or by size.

  2. 02

    Match the context to your work

    Drag the slider to the conversation length you plan to work at. The cache grows with the conversation, and against a card holding 16 GB it is often what pushes a large model over the edge.

  3. 03

    Choose how far you will compress

    Compression is what lets bigger models fit. The quality control drops any model that needs more of it than you are willing to give.

  4. 04

    Take the range as the answer

    Speeds come with error bars for a reason. The best case here is 160 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

    The fit column separates models that just fit from those with room to spare — worth checking before settling on one, against an available 16 GB.

  6. 06

    Open the model to compare cards

    Each model page repeats this calculation for the whole catalogue. Worth a look before deciding: it shows what else runs the same model, alongside Radeon Pro V340 16 GB.

Answers

Radeon Pro V340 16 GB — common questions

01

Radeon Pro V340 16 GB— when was it released?

It was released in August 2018.

02

Radeon Pro V340 16 GB— how much power does it use?

Rated board power is 230 W, and the suggested system power supply is 550 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.

03

Radeon Pro V340 16 GB— how much cache does it have?

The L1 cache is 16 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.

04

Radeon Pro V340 16 GB— what are its TFLOPS?

It is rated at 21.5 TFLOPS at half precision and 10.8 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.

05

Radeon Pro V340 16 GB— does it support CUDA?

No. CUDA is NVIDIA-only, and this is a card from AMD. It runs language models through ROCm, Vulkan or Metal depending on the software, which are less mature than the CUDA path — our estimates apply a penalty for that.

06

Radeon Pro V340 16 GB— what bus interface does it use?

It uses PCIe 3.0 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.

07

Radeon Pro V340 16 GB— is it 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 432 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.

08

Radeon Pro V340 16 GB— can it run a model that does not fit in its memory?

Offloading past the card's 16 GB drags the whole thing down, and none of the figures on this page assume it.

09

Would two Radeon Pro V340 16 GB cards be twice as fast?

No. A second card doubles the memory to 32 GB to work with rather than twice the tokens per second — every figure here is for a single card.

10

Radeon Pro V340 16 GB— which AI models can it run?

432 of the 679 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.

11

Radeon Pro V340 16 GB— what is the largest AI model it can run?

The largest model in our catalogue that fits is Nemotron 3-Nano-30B-A3B at 31.6B parameters, compressed to Q3_K_M. It generates roughly 75.8 tokens per second and needs about 14.4 GB of the card's memory.

12

Radeon Pro V340 16 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 160 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.

13

Radeon Pro V340 16 GB— can it run 7B models?

Yes. For example it runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 23.9 tokens per second.

14

Radeon Pro V340 16 GB— can it run 13B models?

Yes. For example it runs DeepSeekMoE-16B at Q6_K, using about 13.7 GB of memory and generating around 80.6 tokens per second.

15

Radeon Pro V340 16 GB— can it run 30B models?

Yes. For example it runs ERNIE-4.5-VL-28B-A3B at Q3_K_M, using about 12.9 GB of memory and generating around 85.6 tokens per second.

16

Radeon Pro V340 16 GB— how much memory does it have?

This card has 16 GB of HBM2. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 14.4 GB available for a model and its conversation.

17

Radeon Pro V340 16 GB— what is its memory bandwidth?

Memory bandwidth reaches 484 GB/s across a bus of 2,048 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.

18

Radeon Pro V340 16 GB— what type of memory does it use?

It uses HBM2 clocked at 945 MHz. 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.

19

Radeon Pro V340 16 GB— who makes it?

This is a product of AMD, with the chip manufactured by GlobalFoundries, on a process of 14 nm.
