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
What the memory subsystem means for AI
Memory
4 GB
Bandwidth
512 GB/s
Largest model
DeciLM 6B
At 4 GB of HBM the Radeon R9 FURY X 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.
The figure is the memory clock — 500 MHz here — multiplied by the bus width. It is why core counts predict generation speed so poorly.
In practice that combination tops out at DeciLM 6B — 5.7B, compressed to Q3_K_M, generating around 80.1 tokens per second.
The chip and how it was built
The Radeon R9 FURY X is built on the Fiji graphics processor, using AMD's GCN 3.0 architecture, as part of the Pirate Islands(R9 300) 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 June 2015, roughly 11 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
8.6 TFLOPS
FP64
537.6 GFLOPS
On paper the Radeon R9 FURY X reaches 8.6 TFLOPS at half precision and 8.6 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 is 537.6 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 1.05 GHz at base to 1.05 GHz 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 Radeon R9 FURY X 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
275 W
The Radeon R9 FURY X is rated at 275 W, with a 600 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 195 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 R9 FURY X
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
Every one of the 97 models this Radeon R9 FURY X runs is in the table above. Search narrows it by name or by size.
-
02
Set the context length you will actually use
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
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.
-
04
Take the range as the answer
Each speed is an estimate for a single conversation, with a range beneath it — 169 tok/s on Gemma 3 QAT 1B at the top end here. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Read the fit verdict last
The fit column separates models that just fit from those with room to spare — worth checking against the card's 4 GB before settling on one.

Following a model through to its own page lists all the hardware that can run it, so you can see where the Radeon R9 FURY X sits against the alternatives.
Answers
Radeon R9 FURY X — common questions
What is the largest AI model a Radeon R9 FURY X can run?
The largest model in our catalogue that fits on a Radeon R9 FURY X 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 Radeon R9 FURY X produce?
It depends on the model. On a Radeon R9 FURY X 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 Radeon R9 FURY X have?
A Radeon R9 FURY X 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 Radeon R9 FURY X?
The Radeon R9 FURY X 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 Radeon R9 FURY X 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 Radeon R9 FURY X?
The Radeon R9 FURY X is a AMD product, with the chip manufactured by TSMC, on a 28 nm process.
When was the Radeon R9 FURY X released?
The Radeon R9 FURY X was released in June 2015.
How much power does a Radeon R9 FURY X use?
The Radeon R9 FURY X has a rated board power of 275 W, and a 600 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 Radeon R9 FURY X have?
The Radeon R9 FURY X 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.
What are the TFLOPS of a Radeon R9 FURY X?
The Radeon R9 FURY X is rated at 8.6 TFLOPS at half precision and 8.6 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.
Does the Radeon R9 FURY X support CUDA?
No. CUDA is NVIDIA-only, and the Radeon R9 FURY X 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 Radeon R9 FURY X 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 Radeon R9 FURY X 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 Radeon R9 FURY X run a model that does not fit in its memory?
It can be split, with the overflow held in system memory — but that part drags the whole thing down, and none of the 4 GB figures on this page assume it.
Would two Radeon R9 FURY X cards be twice as fast?
Capacity adds, throughput does not. Two of them give you 8 GB to work with rather than twice the tokens per second — every figure here is for a single Radeon R9 FURY X.
What AI models can a Radeon R9 FURY X run?
97 of the 679 open-weight language models we track fit on a Radeon R9 FURY X 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.
