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
The GeForce RTX 3090 Ti carries 24 GB of GDDR6X, which covers the mid-sized models most people actually run — about 21.6 GB of it after the runtime and driver reserve their working space.
Bandwidth is 1,010 GB/s across a 384-bit bus. 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. Both halves matter, and neither is visible in a gaming benchmark.
In practice that combination tops out at Mixtral 8x7B — 46.7B, compressed to Q3_K_M, generating around 89.5 tokens per second.
The chip and how it was built
The GeForce RTX 3090 Ti is built on the GA102 graphics processor, using NVIDIA's Ampere architecture, as part of the GeForce 30 generation.
The chip is manufactured by Samsung, on a 8 nm process, 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 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 the 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 is 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 1.56 GHz at base to 1.86 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 GeForce RTX 3090 Ti has 128 KB of L1 cache, backed by 6 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 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
The GeForce RTX 3090 Ti is rated at 450 W, with a 850 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 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
Every one of the 502 models this GeForce RTX 3090 Ti runs is in the table above. Search narrows it 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; a long document can consume a large share of the card's 24 GB.
-
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. 428 tok/s on Gemma 3 QAT 1B is the fastest result on this card, and like every row it carries a range that reflects how much the runtime matters.
-
05
Check the headroom before you decide
The fit column separates models that just fit from those with room to spare — worth checking against the card's 24 GB before settling on one.
-
06
Open the model to compare cards
Following a model through to its own page lists all the hardware that can run it, so you can see where the GeForce RTX 3090 Ti sits against the alternatives.
Answers
GeForce RTX 3090 Ti — common questions
Would two GeForce RTX 3090 Ti cards be twice as fast?
Pairing GeForce RTX 3090 Ti cards buys headroom rather than pace: 48 GB of combined memory, at roughly the same generation speed as one.
What AI models can a GeForce RTX 3090 Ti run?
502 of the 679 open-weight language models we track fit on a GeForce RTX 3090 Ti 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 GeForce RTX 3090 Ti can run?
The largest model in our catalogue that fits on a GeForce RTX 3090 Ti 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.
How many tokens per second does a GeForce RTX 3090 Ti produce?
It depends on the model. On a GeForce RTX 3090 Ti the fastest model we track 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.
Can a GeForce RTX 3090 Ti run a 7B model?
Yes. For example a GeForce RTX 3090 Ti runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 63.9 tokens per second.
Can a GeForce RTX 3090 Ti run a 13B model?
Yes. For example a GeForce RTX 3090 Ti runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 149 tokens per second.
Can a GeForce RTX 3090 Ti run a 30B model?
Yes. For example a GeForce RTX 3090 Ti runs Nemotron 3-Nano-30B-A3B at Q4_K_M, using about 18.1 GB of memory and generating around 174 tokens per second.
How much memory does a GeForce RTX 3090 Ti have?
A GeForce RTX 3090 Ti has 24 GB of GDDR6X memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 21.6 GB available for a model and its conversation.
What is the memory bandwidth of a GeForce RTX 3090 Ti?
The GeForce RTX 3090 Ti has 1,010 GB/s of memory bandwidth, across a 384-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 GeForce RTX 3090 Ti 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.
Who makes the GeForce RTX 3090 Ti?
The GeForce RTX 3090 Ti is a NVIDIA product, with the chip manufactured by Samsung, on a 8 nm process.
When was the GeForce RTX 3090 Ti released?
The GeForce RTX 3090 Ti was released in January 2022.
How much power does a GeForce RTX 3090 Ti use?
The GeForce RTX 3090 Ti has a rated board power of 450 W, and a 850 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 GeForce RTX 3090 Ti have?
The GeForce RTX 3090 Ti has 128 KB of L1 cache, and 6 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 GeForce RTX 3090 Ti?
The GeForce RTX 3090 Ti 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.
How many tensor cores does a GeForce RTX 3090 Ti have?
The GeForce RTX 3090 Ti 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.
Does the GeForce RTX 3090 Ti support CUDA?
Yes. The GeForce RTX 3090 Ti 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.
What bus interface does the GeForce RTX 3090 Ti 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.
Is the GeForce RTX 3090 Ti 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 502 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a GeForce RTX 3090 Ti run a model that does not fit in its memory?
Offloading past the card's 24 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
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.
