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
Memory: the specification that decides everything
Memory
12 GB
Bandwidth
912 GB/s
Largest model
ERNIE-4.5-21B-A3B
12 GB of GDDR6X puts the GeForce RTX 3080 Ti comfortably into small and mid-sized models, with roughly 10.8 GB usable once the driver overhead is taken out. The largest models are out of reach without splitting them.
Bandwidth is 912 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.
That comes from a 1.19 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.
The practical ceiling is ERNIE-4.5-21B-A3B at 21B, held at Q3_K_M and running at roughly 276 tokens per second.
The chip and how it was built
The GeForce RTX 3080 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 May 2021, roughly 5 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
34.1 TFLOPS
FP64
532.8 GFLOPS
Tensor cores
320
On paper the GeForce RTX 3080 Ti reaches 34.1 TFLOPS at half precision and 34.1 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 532.8 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 320 tensor cores across 80 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 1.37 GHz at base to 1.67 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 3080 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 10,240 shading units, 320 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
350 W
The GeForce RTX 3080 Ti is rated at 350 W, with a 750 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 285 mm long, and needs 1x 12-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 GeForce RTX 3080 Ti
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 GeForce RTX 3080 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
Start with the model, not the specification
All 396 models the GeForce RTX 3080 Ti handles are already listed. The search box takes a name or a size such as 27b, which matches on parameter count.
-
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 on 12 GB it is often what pushes a large model over the edge.
-
03
Choose how far you will compress
Each model is shown at the best compression this card can hold. A minimum quality hides the ones that only fit by being squeezed further than you would accept.
-
04
Look at the range, not just the number
The figures are calculated, not measured. 386 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
Compare what each model needs with the 12 GB this card provides. Tight means it works today; comfortable means it still works when the conversation grows.
-
06
Open the model to compare cards
Each model page repeats this calculation for the whole catalogue. Worth a look before deciding: it shows what else runs the same model, and how the GeForce RTX 3080 Ti compares.
Answers
GeForce RTX 3080 Ti — common questions
What is the largest AI model a GeForce RTX 3080 Ti can run?
The largest model in our catalogue that fits on a GeForce RTX 3080 Ti is ERNIE-4.5-21B-A3B at 21B parameters, compressed to Q3_K_M. It generates roughly 276 tokens per second and needs about 10.1 GB of the card's memory.
How many tokens per second does a GeForce RTX 3080 Ti produce?
It depends on the model. On a GeForce RTX 3080 Ti the fastest model we track is Gemma 3 QAT 1B at about 386 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 3080 Ti run a 7B model?
Yes. For example a GeForce RTX 3080 Ti runs DeepSeek Coder 6.7B at Q6_K, using about 9.9 GB of memory and generating around 83.8 tokens per second.
Can a GeForce RTX 3080 Ti run a 13B model?
Yes. For example a GeForce RTX 3080 Ti runs DeepSeekMoE-16B at Q4_K_M, using about 10.0 GB of memory and generating around 310 tokens per second.
How much memory does a GeForce RTX 3080 Ti have?
A GeForce RTX 3080 Ti has 12 GB of GDDR6X memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 10.8 GB available for a model and its conversation.
What is the memory bandwidth of a GeForce RTX 3080 Ti?
The GeForce RTX 3080 Ti has 912 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 3080 Ti use?
It uses GDDR6X clocked at 1.19 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 3080 Ti?
The GeForce RTX 3080 Ti is a NVIDIA product, with the chip manufactured by Samsung, on a 8 nm process.
When was the GeForce RTX 3080 Ti released?
The GeForce RTX 3080 Ti was released in May 2021.
How much power does a GeForce RTX 3080 Ti use?
The GeForce RTX 3080 Ti has a rated board power of 350 W, and a 750 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 3080 Ti have?
The GeForce RTX 3080 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 3080 Ti?
The GeForce RTX 3080 Ti is rated at 34.1 TFLOPS at half precision and 34.1 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 3080 Ti have?
The GeForce RTX 3080 Ti has 320 tensor cores across 80 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 3080 Ti support CUDA?
Yes. The GeForce RTX 3080 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 3080 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 3080 Ti good for running local AI models?
Its memory covers small and mid-sized models, though the largest are out of reach and its bandwidth is high enough to generate text faster than most people read. 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.
Can a GeForce RTX 3080 Ti run a model that does not fit in its memory?
Only partly. Layers beyond the 12 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.
Would two GeForce RTX 3080 Ti cards be twice as fast?
Pairing GeForce RTX 3080 Ti cards buys headroom rather than pace: 24 GB of combined memory, at roughly the same generation speed as one.
What AI models can a GeForce RTX 3080 Ti run?
396 of the 679 open-weight language models we track fit on a GeForce RTX 3080 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.
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.
