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
6 GB
Bandwidth
288 GB/s
Largest model
Qwen-VL
At 6 GB of GDDR5 the GeForce GTX 780 6 GB is limited to the smaller end of the catalogue. About 5.4 GB is actually available to a runtime, and a model has to fit entirely inside it before generating anything at all.
At 288 GB/s across a 384-bit bus, bandwidth is this card's real constraint. Every token requires reading the entire model out of memory, so a large model will feel slow here even when it fits.
That comes from a 1.5 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 Qwen-VL at 9.6B, held at Q3_K_M and running at roughly 29.2 tokens per second.
The chip and how it was built
The GeForce GTX 780 6 GB is built on the GK110B graphics processor, using NVIDIA's Kepler architecture, as part of the GeForce 700 generation.
The chip is manufactured by TSMC, on a 28 nm process, with a die measuring 561 mm², holding 7.1 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 September 2013, 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
173.2 GFLOPS
Double-precision throughput is 173.2 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 863 MHz at base to 902 MHz 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 GTX 780 6 GB has 16 KB of L1 cache, backed by 1.5 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 2,304 shading units, 192 texture mapping units, and 48 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
250 W
The GeForce GTX 780 6 GB is rated at 250 W, with a 600 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 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 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 GeForce GTX 780 6 GB
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 266 models this GeForce GTX 780 6 GB runs is in the table above. Search narrows it by name or by size.
-
02
Set the context length you will actually use
Longer conversations cost memory on top of the weights. With 6 GB to work in, that is frequently the difference between a model fitting and not.
-
03
Pin the comparison to one quality level
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
Each speed is an estimate for a single conversation, with a range beneath it — 104 tok/s on Gemma 3 QAT 1B at the top end here. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Check the memory column before committing
Compare what each model needs with the 6 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
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 GeForce GTX 780 6 GB is the right buy for it or merely a card that fits.
Answers
GeForce GTX 780 6 GB — common questions
What type of memory does a GeForce GTX 780 6 GB use?
It uses GDDR5 clocked at 1.5 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 GTX 780 6 GB?
The GeForce GTX 780 6 GB is a NVIDIA product, with the chip manufactured by TSMC, on a 28 nm process.
When was the GeForce GTX 780 6 GB released?
The GeForce GTX 780 6 GB was released in September 2013.
How much power does a GeForce GTX 780 6 GB use?
The GeForce GTX 780 6 GB has a rated board power of 250 W, and a 600 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 GTX 780 6 GB have?
The GeForce GTX 780 6 GB has 16 KB of L1 cache, and 1.5 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 GeForce GTX 780 6 GB support CUDA?
Yes. The GeForce GTX 780 6 GB reports CUDA compute capability 3.5, which predates tensor cores. 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 GTX 780 6 GB 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 GeForce GTX 780 6 GB 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 266 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 GTX 780 6 GB run a model that does not fit in its memory?
Only partly. Layers beyond the 6 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 GTX 780 6 GB cards be twice as fast?
No. A second GeForce GTX 780 6 GB doubles the memory to 12 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 GeForce GTX 780 6 GB run?
266 of the 679 open-weight language models we track fit on a GeForce GTX 780 6 GB 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 GTX 780 6 GB can run?
The largest model in our catalogue that fits on a GeForce GTX 780 6 GB is Qwen-VL at 9.6B parameters, compressed to Q3_K_M. It generates roughly 29.2 tokens per second and needs about 5.4 GB of the card's memory.
How many tokens per second does a GeForce GTX 780 6 GB produce?
It depends on the model. On a GeForce GTX 780 6 GB the fastest model we track is Gemma 3 QAT 1B at about 104 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 GTX 780 6 GB run a 7B model?
Yes. For example a GeForce GTX 780 6 GB runs MetaMath 7B (Mistral finetune) at IQ4_XS, using about 5.1 GB of memory and generating around 36.4 tokens per second.
How much memory does a GeForce GTX 780 6 GB have?
A GeForce GTX 780 6 GB has 6 GB of GDDR5 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 5.4 GB available for a model and its conversation.
What is the memory bandwidth of a GeForce GTX 780 6 GB?
The GeForce GTX 780 6 GB has 288 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.
The other direction
Looking at it from the other side?
