What the numbers mean
Why memory is the number that matters here
Memory
24 GB
Bandwidth
288 GB/s
Largest model
Mixtral 8x7B
The Tesla M40 24 GB carries 24 GB of GDDR5, 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.
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.
Bandwidth is clock times bus width, and this card clocks its memory at 1.5 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 21.7 tokens per second.
The chip and how it was built
The Tesla M40 24 GB is built on the GM200 graphics processor, using NVIDIA's Maxwell 2.0 architecture, as part of the Tesla Maxwell(Mxx) generation.
The chip is manufactured by TSMC, on a 28 nm process, with a die measuring 601 mm², holding 8 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 November 2015, roughly 10 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
213.5 GFLOPS
Double-precision throughput is 213.5 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 948 MHz at base to 1.11 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 Tesla M40 24 GB has 48 KB of L1 cache, backed by 3 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 3,072 shading units, 192 texture mapping units, and 96 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 Tesla M40 24 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 8-pin EPS. 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.

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 Tesla M40 24 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
Search for the model you want
The table lists 502 models this Tesla M40 24 GB can run. Search by name, or by size — typing 27b matches on the parameter count even when the name never states it.
-
02
Match the context to your work
Longer conversations cost memory on top of the weights. With 24 GB to work in, that is frequently the difference between a model fitting and not.
-
03
Pin the comparison to one quality level
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
Read the speed and the range
Speeds come with error bars for a reason. The best case here is 104 tok/s on Gemma 3 QAT 1B, and which inference software you use moves that by thirty to fifty per cent.
-
05
Check the headroom before you decide
A tight fit runs but leaves no room to raise the context later; comfortable has headroom. The memory column shows what each model needs against the 24 GB available.
-
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 Tesla M40 24 GB is the right buy for it or merely a card that fits.
Answers
Tesla M40 24 GB — common questions
How much power does a Tesla M40 24 GB use?
The Tesla M40 24 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 Tesla M40 24 GB have?
The Tesla M40 24 GB has 48 KB of L1 cache, and 3 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 Tesla M40 24 GB support CUDA?
Yes. The Tesla M40 24 GB reports CUDA compute capability 5.2, 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 Tesla M40 24 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 Tesla M40 24 GB good for running local AI models?
Its memory comfortably covers the mid-sized models most people run locally though its bandwidth means generation will feel slow on larger models. 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 Tesla M40 24 GB 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.
Would two Tesla M40 24 GB cards be twice as fast?
No. A second Tesla M40 24 GB doubles the memory to 48 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 Tesla M40 24 GB run?
502 of the 679 open-weight language models we track fit on a Tesla M40 24 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 Tesla M40 24 GB can run?
The largest model in our catalogue that fits on a Tesla M40 24 GB is Mixtral 8x7B at 46.7B parameters, compressed to Q3_K_M. It generates roughly 21.7 tokens per second and needs about 21.0 GB of the card's memory.
How many tokens per second does a Tesla M40 24 GB produce?
It depends on the model. On a Tesla M40 24 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 Tesla M40 24 GB run a 7B model?
Yes. For example a Tesla M40 24 GB runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 15.5 tokens per second.
Can a Tesla M40 24 GB run a 13B model?
Yes. For example a Tesla M40 24 GB runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 36.1 tokens per second.
Can a Tesla M40 24 GB run a 30B model?
Yes. For example a Tesla M40 24 GB runs Nemotron 3-Nano-30B-A3B at Q4_K_M, using about 18.1 GB of memory and generating around 42.1 tokens per second.
How much memory does a Tesla M40 24 GB have?
A Tesla M40 24 GB has 24 GB of GDDR5 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 Tesla M40 24 GB?
The Tesla M40 24 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.
What type of memory does a Tesla M40 24 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 Tesla M40 24 GB?
The Tesla M40 24 GB is a NVIDIA product, with the chip manufactured by TSMC, on a 28 nm process.
When was the Tesla M40 24 GB released?
The Tesla M40 24 GB was released in November 2015.
