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

Largest model
DeciLM 6B
At 4 GB of HBM the FirePro S9300 X2 is limited to the smaller end of the catalogue. About 3.6 GB is actually available to a runtime, and a model has to fit entirely inside it before generating anything at all.
The memory bus moves 512 GB/s across a 4,096-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.
That comes from a 500 MHz memory clock across the bus width above. 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 practical ceiling is DeciLM 6B at 5.7B, held at Q3_K_M and running at roughly 80.1 tokens per second.
The chip and how it was built
The FirePro S9300 X2 is built on the Capsaicin graphics processor, using AMD's GCN 3.0 architecture, as part of the FirePro Server(Sx300) generation.
The chip is manufactured by TSMC, on a 28 nm process, with a die measuring 596 mm², holding 8.9 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 2016, roughly 10 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
FP64
499.2 GFLOPS
Double-precision throughput is 499.2 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 975 MHz at base to 975 MHz 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 FirePro S9300 X2 has 16 KB of L1 cache, backed by 2 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 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
300 W
The FirePro S9300 X2 is rated at 300 W, with a 700 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 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.
The extremes

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 FirePro S9300 X2
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 FirePro S9300 X2
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 97 models this FirePro S9300 X2 can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Match the context to your work
Set the context to your real working length. Short questions cost almost nothing; a long document can consume a large share of the card's 4 GB.
-
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
Read the speed and the range
Speeds come with error bars for a reason. The best case here is 169 tok/s on Gemma 3 QAT 1B, and which inference software you use moves that by thirty to fifty per cent.
-
05
Check the headroom before you decide
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 4 GB available.
-
06
Check the same model from the other side
Each model page repeats this calculation for the whole catalogue. Worth a look before deciding: it shows what else runs the same model, and how the FirePro S9300 X2 compares.
Answers
FirePro S9300 X2 — common questions
When was the FirePro S9300 X2 released?
The FirePro S9300 X2 was released in March 2016.
How much power does a FirePro S9300 X2 use?
The FirePro S9300 X2 has a rated board power of 300 W, and a 700 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.
How much cache does a FirePro S9300 X2 have?
The FirePro S9300 X2 has 16 KB of L1 cache, and 2 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.
Does the FirePro S9300 X2 support CUDA?
No. CUDA is NVIDIA-only, and the FirePro S9300 X2 is a AMD card. 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.
What bus interface does the FirePro S9300 X2 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.
Is the FirePro S9300 X2 good for running local AI models?
Its memory limits it to smaller models and its bandwidth gives usable, if unspectacular, generation speeds. In total it runs 97 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a FirePro S9300 X2 run a model that does not fit in its memory?
Only partly. Layers beyond the 4 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 FirePro S9300 X2 cards be twice as fast?
Pairing FirePro S9300 X2 cards buys headroom rather than pace: 8 GB of combined memory, at roughly the same generation speed as one.
What AI models can a FirePro S9300 X2 run?
97 of the 679 open-weight language models we track fit on a FirePro S9300 X2 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.
What is the largest AI model a FirePro S9300 X2 can run?
The largest model in our catalogue that fits on a FirePro S9300 X2 is DeciLM 6B at 5.7B parameters, compressed to Q3_K_M. It generates roughly 80.1 tokens per second and needs about 3.5 GB of the card's memory.
How many tokens per second does a FirePro S9300 X2 produce?
It depends on the model. On a FirePro S9300 X2 the fastest model we track is Gemma 3 QAT 1B at about 169 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.
How much memory does a FirePro S9300 X2 have?
A FirePro S9300 X2 has 4 GB of HBM memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 3.6 GB available for a model and its conversation.
What is the memory bandwidth of a FirePro S9300 X2?
The FirePro S9300 X2 has 512 GB/s of memory bandwidth, across a 4,096-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.
What type of memory does a FirePro S9300 X2 use?
It uses HBM clocked at 500 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.
Who makes the FirePro S9300 X2?
The FirePro S9300 X2 is a AMD product, with the chip manufactured by TSMC, on a 28 nm process.
