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
Why memory is the number that matters here
Memory
4 GB
Bandwidth
320 GB/s
Largest model
DeciLM 6B
At 4 GB of GDDR5 the Radeon R9 295X2 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 320 GB/s across a 512-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 1.25 GHz 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.
In practice that combination tops out at DeciLM 6B — 5.7B, compressed to Q3_K_M, generating around 50.1 tokens per second.
The chip and how it was built
The Radeon R9 295X2 is built on the Vesuvius graphics processor, using AMD's GCN 2.0 architecture, as part of the Volcanic Islands(R9 200) generation.
The chip is manufactured by TSMC, on a 28 nm process, with a die measuring 438 mm², holding 6.2 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 April 2014, roughly 12 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
716.7 GFLOPS
Double-precision throughput is 716.7 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 1.02 GHz at base to 1.02 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 295X2 has 16 KB of L1 cache, backed by 1 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 2,816 shading units, 176 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
500 W
The Radeon R9 295X2 is rated at 500 W, with a 900 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 307 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 295X2
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 Radeon R9 295X2 can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Decide how long your conversations run
Longer conversations cost memory on top of the weights. With 4 GB to work in, that is frequently the difference between a model fitting and not.
-
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 106 tok/s on Gemma 3 QAT 1B, and which inference software you use moves that by thirty to fifty per cent.
-
05
Check the memory column before committing
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.
-
06
Cross-check against other hardware
Every model name in the table links to its own page, which runs the same calculation across every card we hold. That is where you see whether the Radeon R9 295X2 is the right buy for it or merely a card that fits.
Answers
Radeon R9 295X2 — common questions
What bus interface does the Radeon R9 295X2 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 295X2 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 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 295X2 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 295X2 cards be twice as fast?
No. A second Radeon R9 295X2 doubles the memory to 8 GB, which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.
What AI models can a Radeon R9 295X2 run?
97 of the 679 open-weight language models we track fit on a Radeon R9 295X2 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 Radeon R9 295X2 can run?
The largest model in our catalogue that fits on a Radeon R9 295X2 is DeciLM 6B at 5.7B parameters, compressed to Q3_K_M. It generates roughly 50.1 tokens per second and needs about 3.5 GB of the card's memory.
How many tokens per second does a Radeon R9 295X2 produce?
It depends on the model. On a Radeon R9 295X2 the fastest model we track is Gemma 3 QAT 1B at about 106 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 295X2 have?
A Radeon R9 295X2 has 4 GB of GDDR5 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 295X2?
The Radeon R9 295X2 has 320 GB/s of memory bandwidth, across a 512-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 295X2 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.
Who makes the Radeon R9 295X2?
The Radeon R9 295X2 is a AMD product, with the chip manufactured by TSMC, on a 28 nm process.
When was the Radeon R9 295X2 released?
The Radeon R9 295X2 was released in April 2014.
How much power does a Radeon R9 295X2 use?
The Radeon R9 295X2 has a rated board power of 500 W, and a 900 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 295X2 have?
The Radeon R9 295X2 has 16 KB of L1 cache, and 1 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 Radeon R9 295X2 support CUDA?
No. CUDA is NVIDIA-only, and the Radeon R9 295X2 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.
