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
32 GB
Bandwidth
825 GB/s
Largest model
Phi-3.5-MoE
Radeon Pro Vega II carries 32 GB of HBM2. That covers the mid-sized models most people actually run. Once the runtime and driver reserve their working space, roughly this much is left: 28.8 GB.
Memory bandwidth reaches 825 GB/s across a bus of 4,096 bits. Generating a token means reading every weight once, so that figure sets the pace more than any other number here, and at this level text arrives faster than most people read.
The figure is the bus width multiplied by a memory clock of 806 MHz. 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.
The biggest thing it holds is Phi-3.5-MoE, 60.8B, compressed to Q3_K_M and generating around 67.2 tokens per second.
The chip and how it was built
Radeon Pro Vega II is built on the graphics processor Vega 20, using the architecture GCN 5.1 from AMD, as part of the generation Radeon Pro Mac(Vega Series).
The chip is manufactured by TSMC, on a process of 7 nm, with a die measuring 331 mm², holding 13.2 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 June 2019, roughly 7.2813446110381 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
28.2 TFLOPS
FP64
7 TFLOPS
On paper Radeon Pro Vega II reaches 28.2 TFLOPS at half precision, and 14.1 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 7 TFLOPS. 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 1.57 GHz to a boost of 1.72 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 Vega II 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 4,096 shading units, 256 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
475 W
Radeon Pro Vega II is rated at 475 W, and the suggested system power supply is 850 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 quad-slot. 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 Apple MPX. 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 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 Radeon Pro Vega II
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 Radeon Pro Vega II
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 543 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.
-
02
Set the context length you will actually use
Longer conversations cost memory on top of the weights. Against 32 GB it is often what pushes a large model over the edge.
-
03
Choose how far you will compress
By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.
-
04
Take the range as the answer
Each speed is an estimate for a single conversation, with a range beneath it. The top end here is 273 tok/s on Gemma 3 QAT 1B. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
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 32 GB.
-
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 Vega II.
Answers
Radeon Pro Vega II — common questions
Radeon Pro Vega II— who makes it?
This is a product of AMD, with the chip manufactured by TSMC, on a process of 7 nm.
Radeon Pro Vega II— when was it released?
It was released in June 2019.
Radeon Pro Vega II— how much power does it use?
Rated board power is 475 W, and the suggested system power supply is 850 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.
Radeon Pro Vega II— 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.
Radeon Pro Vega II— what are its TFLOPS?
It is rated at 28.2 TFLOPS at half precision and 14.1 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.
Radeon Pro Vega II— 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.
Radeon Pro Vega II— what bus interface does it use?
It uses Apple MPX. 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.
Radeon Pro Vega II— is it good for running local AI models?
Its memory comfortably covers the mid-sized models most people run locally and its bandwidth is high enough to generate text faster than most people read. In total it runs 543 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Radeon Pro Vega II— can it run a model that does not fit in its memory?
Offloading past the card's 32 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
Would two Radeon Pro Vega II cards be twice as fast?
No. A second card doubles the memory to 64 GB which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.
Radeon Pro Vega II— which AI models can it run?
543 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.
Radeon Pro Vega II— what is the largest AI model it can run?
The largest model in our catalogue that fits is Phi-3.5-MoE at 60.8B parameters, compressed to Q3_K_M. It generates roughly 67.2 tokens per second and needs about 27.2 GB of the card's memory.
Radeon Pro Vega II— 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 273 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.
Radeon Pro Vega II— 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 60.6 tokens per second.
Radeon Pro Vega II— 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 94.7 tokens per second.
Radeon Pro Vega II— can it run 30B models?
Yes. For example it runs ERNIE-4.5-VL-28B-A3B at Q6_K, using about 22.7 GB of memory and generating around 78.6 tokens per second.
Radeon Pro Vega II— how much memory does it have?
This card has 32 GB of HBM2. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 28.8 GB available for a model and its conversation.
Radeon Pro Vega II— what is its memory bandwidth?
Memory bandwidth reaches 825 GB/s across a bus of 4,096 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.
Radeon Pro Vega II— what type of memory does it use?
It uses HBM2 clocked at 806 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.
The other direction
Looking at it from the other side?
