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
8 GB
Bandwidth
243 GB/s
Largest model
Baichuan 1-13B
Quadro P4000 carries only 8 GB of GDDR5. That limits it to the smaller end of the catalogue, and a model has to fit entirely inside before it generates anything at all. A runtime actually gets about 7.2 GB.
Memory bandwidth reaches 243 GB/s across a bus of 256 bits. 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.
Bandwidth is clock times bus width, and this card clocks its memory at 1.9 GHz. It is why core counts predict generation speed so poorly.
Put together, the largest model that fits is Baichuan 1-13B, 13.3B, compressed to Q3_K_M and generating around 17.8 tokens per second.
The chip and how it was built
Quadro P4000 is built on the graphics processor GP104, using the architecture Pascal from NVIDIA, as part of the generation Quadro Pascal(Px000).
The chip is manufactured by TSMC, on a process of 16 nm, with a die measuring 314 mm², holding 7.2 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 February 2017, roughly 9.6018896840274 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
82.9 GFLOPS
FP64
165.8 GFLOPS
On paper Quadro P4000 reaches 82.9 GFLOPS at half precision, and 5.3 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 165.8 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.
Clocks run from a base of 1.2 GHz to a boost of 1.48 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
Quadro P4000 has an L1 cache of 48 KB, backed by an L2 cache of 2 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 1,792 shading units, 112 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
105 W
Quadro P4000 is rated at 105 W, and the suggested system power supply is 300 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 single-slot, measuring 241 mm long, and needs 1x 6-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.
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 Quadro P4000
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 Quadro P4000
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 351 models this card can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Set the context length you will actually use
Longer conversations cost memory on top of the weights. Against 8 GB so the setting is worth getting right.
-
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
Take the range as the answer
Each speed is an estimate for a single conversation, with a range beneath it. The top end here is 87.6 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 memory column before committing
Tight means it works today; comfortable means it still works when the conversation grows. Compare what each model needs against an available 8 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 Quadro P4000.
Answers
Quadro P4000 — common questions
Quadro P4000— how much power does it use?
Rated board power is 105 W, and the suggested system power supply is 300 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.
Quadro P4000— how much cache does it have?
The L1 cache is 48 KB, and the L2 cache is 2 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.
Quadro P4000— what are its TFLOPS?
It is rated at 82.9 GFLOPS at half precision and 5.3 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.
Quadro P4000— does it support CUDA?
Yes. It reports CUDA compute capability 6.1, 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.
Quadro P4000— what bus interface does it 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.
Quadro P4000— is it 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 351 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Quadro P4000— 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 8 GB drags the whole thing down, and none of the figures on this page assume it.
Would two Quadro P4000 cards be twice as fast?
Capacity adds, throughput does not. Two of them give you 16 GB which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.
Quadro P4000— which AI models can it run?
351 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.
Quadro P4000— what is the largest AI model it can run?
The largest model in our catalogue that fits is Baichuan 1-13B at 13.3B parameters, compressed to Q3_K_M. It generates roughly 17.8 tokens per second and needs about 7.2 GB of the card's memory.
Quadro P4000— 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 87.6 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.
Quadro P4000— can it run 7B models?
Yes. For example it runs Gemma 4 E4B at Q5_K_M, using about 7.0 GB of memory and generating around 34.8 tokens per second.
Quadro P4000— can it run 13B models?
Yes. For example it runs Gemma 4 12B at Q3_K_M, using about 6.5 GB of memory and generating around 19.8 tokens per second.
Quadro P4000— how much memory does it have?
This card has 8 GB of GDDR5. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 7.2 GB available for a model and its conversation.
Quadro P4000— what is its memory bandwidth?
Memory bandwidth reaches 243 GB/s across a bus of 256 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.
Quadro P4000— what type of memory does it use?
It uses GDDR5 clocked at 1.9 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.
Quadro P4000— who makes it?
This is a product of NVIDIA, with the chip manufactured by TSMC, on a process of 16 nm.
Quadro P4000— when was it released?
It was released in February 2017.
