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.

Memory: the specification that decides everything
Memory
12 GB
Bandwidth
384 GB/s
Largest model
ERNIE-4.5-21B-A3B
Radeon RX 6700 XT carries 12 GB of GDDR6. That reaches comfortably into small and mid-sized models, though the largest stay out of reach without splitting them. Driver overhead leaves roughly 10.8 GB.
Memory bandwidth reaches 384 GB/s across a bus of 192 bits. That is the number governing generation speed — arithmetic per byte read is small enough that the bus, not the cores, is what everything waits on.
That comes from a memory clock of 2 GHz. Both halves matter, and neither is visible in a gaming benchmark.
The practical ceiling is ERNIE-4.5-21B-A3B, 21B, compressed to Q3_K_M and generating around 90.6 tokens per second.
The chip and how it was built
Radeon RX 6700 XT is built on the graphics processor Navi 22, using the architecture RDNA 2.0 from AMD, as part of the generation Navi II(RX 6000).
The chip is manufactured by TSMC, on a process of 7 nm, with a die measuring 335 mm², holding 17.2 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 March 2021, roughly 5.4137211561343 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
26.4 TFLOPS
FP64
825.9 GFLOPS
On paper Radeon RX 6700 XT reaches 26.4 TFLOPS at half precision, and 13.2 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 825.9 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 2.32 GHz to a boost of 2.58 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 RX 6700 XT has an L1 cache of 128 KB, backed by an L2 cache of 3 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 2,560 shading units, 160 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
230 W
Radeon RX 6700 XT is rated at 230 W, and the suggested system power supply is 550 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 dual-slot, measuring 267 mm long, and needs 1x 6-pin + 1x 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 4.0 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 Radeon RX 6700 XT
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 RX 6700 XT
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
Search for the model you want
The table lists 396 models this card runs. Search narrows the list by name or by size.
-
02
Decide how long your conversations run
Drag the slider to the conversation length you plan to work at. The cache grows with the conversation, and against a card holding 12 GB so the setting is worth getting right.
-
03
Choose how far you will compress
Compression is what lets bigger models fit. The quality control drops any model that needs more of it than you are willing to give.
-
04
Take the range as the answer
The figures are calculated, not measured. The fastest result on this card is 127 tok/s on Gemma 3 QAT 1B. 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 before settling on one, against an available 12 GB.
-
06
Check the same model from the other side
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 right buy is Radeon RX 6700 XT.
Answers
Radeon RX 6700 XT — common questions
Radeon RX 6700 XT— what bus interface does it use?
It uses PCIe 4.0 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 RX 6700 XT— is it good for running local AI models?
Its memory covers small and mid-sized models, though the largest are out of reach though its bandwidth means generation will feel slow on larger models. In total it runs 396 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Radeon RX 6700 XT— 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 12 GB drags the whole thing down, and none of the figures on this page assume it.
Would two Radeon RX 6700 XT cards be twice as fast?
Capacity adds, throughput does not. Two of them give you 24 GB of combined memory, at roughly the same generation speed as one.
Radeon RX 6700 XT— which AI models can it run?
396 of the 679 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 RX 6700 XT— what is the largest AI model it can run?
The largest model in our catalogue that fits is ERNIE-4.5-21B-A3B at 21B parameters, compressed to Q3_K_M. It generates roughly 90.6 tokens per second and needs about 10.1 GB of the card's memory.
Radeon RX 6700 XT— 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 127 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 RX 6700 XT— can it run 7B models?
Yes. For example it runs DeepSeek Coder 6.7B at Q6_K, using about 9.9 GB of memory and generating around 27.5 tokens per second.
Radeon RX 6700 XT— can it run 13B models?
Yes. For example it runs DeepSeekMoE-16B at Q4_K_M, using about 10.0 GB of memory and generating around 102 tokens per second.
Radeon RX 6700 XT— how much memory does it have?
This card has 12 GB of GDDR6. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 10.8 GB available for a model and its conversation.
Radeon RX 6700 XT— what is its memory bandwidth?
Memory bandwidth reaches 384 GB/s across a bus of 192 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 RX 6700 XT— what type of memory does it use?
It uses GDDR6 clocked at 2 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 RX 6700 XT— who makes it?
This is a product of AMD, with the chip manufactured by TSMC, on a process of 7 nm.
Radeon RX 6700 XT— when was it released?
It was released in March 2021.
Radeon RX 6700 XT— how much power does it use?
Rated board power is 230 W, and the suggested system power supply is 550 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 RX 6700 XT— how much cache does it have?
The L1 cache is 128 KB, and the L2 cache is 3 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 RX 6700 XT— what are its TFLOPS?
It is rated at 26.4 TFLOPS at half precision and 13.2 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 RX 6700 XT— 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.
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.
