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.

Capacity and bandwidth
Memory

Bandwidth
160 GB/s
Largest model
Baichuan 1-13B
Radeon E9390 PCIe carries only 8 GB of GDDR5. That limits it to the smaller end of the catalogue, and a model has to fit entirely inside before it generates anything at all. A runtime actually gets about 7.2 GB.
Memory bandwidth reaches 160 GB/s across a bus of 256 bits. Bandwidth is this card's real constraint. Every token requires reading the entire model out of memory, so a large model will feel slow here even when it fits.
That comes from a memory clock of 1.25 GHz. It is why core counts predict generation speed so poorly.
Put together, the largest model that fits is Baichuan 1-13B, 13.3B, compressed to Q3_K_M and generating around 10.8 tokens per second.
The chip and how it was built
Radeon E9390 PCIe is built on the graphics processor Ellesmere, using the architecture GCN 4.0 from AMD, as part of the generation Embedded(9000).
The chip is manufactured by GlobalFoundries, on a process of 14 nm, with a die measuring 232 mm², holding 5.7 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 2019, roughly 6.9142200244632 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
3.9 TFLOPS
FP64
243.9 GFLOPS
On paper Radeon E9390 PCIe reaches 3.9 TFLOPS at half precision, and 3.9 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 243.9 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.
Clocks run from a base of 713 MHz to a boost of 1.09 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 E9390 PCIe has an L1 cache of 16 KB, backed by an L2 cache of 2 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 1,792 shading units, 112 texture mapping units, and 32 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
75 W
Radeon E9390 PCIe is rated at 75 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 single-slot, measuring 173 mm long. 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 E9390 PCIe
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
Find the model in the table
The table lists 351 models this card runs. Search narrows the list by name or by size.
-
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 8 GB so the setting is worth getting right.
-
03
Set a minimum quality if you need one
By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.
-
04
Read the speed and the range
Speeds come with error bars for a reason. The best case here is 52.9 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 memory column before committing
Tight means it works today; comfortable means it still works when the conversation grows. Compare what each model needs against an available 8 GB.
-
06
Check the same model from the other side
Following a model through to its own page lists all the hardware that can run it, so you can see how it compares against Radeon E9390 PCIe.
Answers
Radeon E9390 PCIe — common questions
Radeon E9390 PCIe— which AI models can it run?
351 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 E9390 PCIe— what is the largest AI model it can run?
The largest model in our catalogue that fits is Baichuan 1-13B at 13.3B parameters, compressed to Q3_K_M. It generates roughly 10.8 tokens per second and needs about 7.2 GB of the card's memory.
Radeon E9390 PCIe— 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 52.9 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 E9390 PCIe— can it run 7B models?
Yes. For example it runs Gemma 4 E4B at Q5_K_M, using about 7.0 GB of memory and generating around 21.0 tokens per second.
Radeon E9390 PCIe— can it run 13B models?
Yes. For example it runs Gemma 4 12B at Q3_K_M, using about 6.5 GB of memory and generating around 11.9 tokens per second.
Radeon E9390 PCIe— how much memory does it have?
This card has 8 GB of GDDR5. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 7.2 GB available for a model and its conversation.
Radeon E9390 PCIe— what is its memory bandwidth?
Memory bandwidth reaches 160 GB/s across a bus of 256 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 E9390 PCIe— what type of memory does it use?
It uses GDDR5 clocked at 1.25 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.
Radeon E9390 PCIe— who makes it?
This is a product of AMD, with the chip manufactured by GlobalFoundries, on a process of 14 nm.
Radeon E9390 PCIe— when was it released?
It was released in October 2019.
Radeon E9390 PCIe— how much power does it use?
Rated board power is 75 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 E9390 PCIe— how much cache does it have?
The L1 cache is 16 KB, and the L2 cache is 2 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 E9390 PCIe— what are its TFLOPS?
It is rated at 3.9 TFLOPS at half precision and 3.9 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 E9390 PCIe— 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 E9390 PCIe— 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.
Radeon E9390 PCIe— is it good for running local AI models?
Its memory limits it to smaller models though its bandwidth means generation will feel slow on larger models. In total it runs 351 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Radeon E9390 PCIe— can it run a model that does not fit in its memory?
It can be split, with the overflow held in system memory beyond the card's 8 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.
Would two Radeon E9390 PCIe cards be twice as fast?
Capacity adds, throughput does not. Two of them give you 16 GB of combined memory, at roughly the same generation speed as one.
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.
