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
24 GB
Bandwidth
1,010 GB/s
Largest model
Mixtral 8x7B
GeForce RTX 3090 Ti carries 24 GB of GDDR6X. That covers the mid-sized models most people actually run. Once the runtime and driver reserve their working space, roughly this much is left: 21.6 GB.
Memory bandwidth reaches 1,010 GB/s across a bus of 384 bits. Generating a token means reading every weight once, so that figure sets the pace more than any other number here, and at this level text arrives faster than most people read.
Bandwidth is clock times bus width, and this card clocks its memory at 1.31 GHz. It is why core counts predict generation speed so poorly.
In practice that combination tops out at Mixtral 8x7B, 46.7B, compressed to Q3_K_M and generating around 89.5 tokens per second.
The chip and how it was built
GeForce RTX 3090 Ti is built on the graphics processor GA102, using the architecture Ampere from NVIDIA, as part of the generation GeForce 30.
The chip is manufactured by Samsung, on a process of 8 nm, with a die measuring 628 mm², holding 28.3 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 January 2022, roughly 4.6289436834654 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
40 TFLOPS
FP64
625 GFLOPS
Tensor cores
336
On paper GeForce RTX 3090 Ti reaches 40 TFLOPS at half precision, and 40 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 625 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.
The card carries 336 tensor cores across 84 streaming multiprocessors. These accelerate the matrix arithmetic at the heart of a transformer, and they are what make prompt processing — reading a long document before answering — dramatically faster than it would otherwise be.
Clocks run from a base of 1.56 GHz to a boost of 1.86 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
GeForce RTX 3090 Ti has an L1 cache of 128 KB, backed by an L2 cache of 6 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 10,752 shading units, 336 texture mapping units, and 112 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
450 W
GeForce RTX 3090 Ti is rated at 450 W, and the suggested system power supply is 850 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 triple-slot, measuring 336 mm long, and needs 1x 16-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.

Step by step
How to work out the tokens per second of a GeForce RTX 3090 Ti
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 532 models this card runs. Search narrows the list by name or by size.
-
02
Decide how long your conversations run
Set the context to your real working length. Short questions cost almost nothing, but a long document can consume a large share of 24 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
Look at the range, not just the number
The figures are calculated, not measured. The fastest result on this card is 428 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 headroom before you decide
The fit column separates models that just fit from those with room to spare — worth checking before settling on one, against an available 24 GB.

Following a model through to its own page lists all the hardware that can run it, so you can see how it compares against GeForce RTX 3090 Ti.
Answers
GeForce RTX 3090 Ti — common questions
Would two GeForce RTX 3090 Ti cards be twice as fast?
Pairing them buys headroom rather than pace: 48 GB of combined memory, at roughly the same generation speed as one.
GeForce RTX 3090 Ti— which AI models can it run?
532 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.
GeForce RTX 3090 Ti— what is the largest AI model it can run?
The largest model in our catalogue that fits is Mixtral 8x7B at 46.7B parameters, compressed to Q3_K_M. It generates roughly 89.5 tokens per second and needs about 21.0 GB of the card's memory.
GeForce RTX 3090 Ti— 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 428 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.
GeForce RTX 3090 Ti— can it run 7B models?
Yes. For example it runs Gemma 4 E4B at Q8_0, using about 9.8 GB of memory and generating around 95.1 tokens per second.
GeForce RTX 3090 Ti— can it run 13B models?
Yes. For example it runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 149 tokens per second.
GeForce RTX 3090 Ti— can it run 30B models?
Yes. For example it runs Nemotron 3-Nano-30B-A3B at Q4_K_M, using about 18.1 GB of memory and generating around 174 tokens per second.
GeForce RTX 3090 Ti— how much memory does it have?
This card has 24 GB of GDDR6X. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 21.6 GB available for a model and its conversation.
GeForce RTX 3090 Ti— what is its memory bandwidth?
Memory bandwidth reaches 1,010 GB/s across a bus of 384 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.
GeForce RTX 3090 Ti— what type of memory does it use?
It uses GDDR6X clocked at 1.31 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.
GeForce RTX 3090 Ti— who makes it?
This is a product of NVIDIA, with the chip manufactured by Samsung, on a process of 8 nm.
GeForce RTX 3090 Ti— when was it released?
It was released in January 2022.
GeForce RTX 3090 Ti— how much power does it use?
Rated board power is 450 W, and the suggested system power supply is 850 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.
GeForce RTX 3090 Ti— how much cache does it have?
The L1 cache is 128 KB, and the L2 cache is 6 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.
GeForce RTX 3090 Ti— what are its TFLOPS?
It is rated at 40 TFLOPS at half precision and 40 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.
GeForce RTX 3090 Ti— how many tensor cores does it have?
It has 336 tensor cores across 84 streaming multiprocessors. They accelerate the matrix arithmetic a transformer is built from, which mainly speeds up processing a long prompt rather than producing the reply.
GeForce RTX 3090 Ti— does it support CUDA?
Yes. It reports CUDA compute capability 8.6. Capability 7.0 and above has tensor cores, which modern inference software uses; below that it falls back to slower code paths for quantised models.
GeForce RTX 3090 Ti— 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.
GeForce RTX 3090 Ti— is it good for running local AI models?
Its memory comfortably covers the mid-sized models most people run locally and its bandwidth is high enough to generate text faster than most people read. In total it runs 532 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
GeForce RTX 3090 Ti— can it run a model that does not fit in its memory?
Offloading past the card's 24 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.
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.
