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
Capacity and bandwidth
Memory
4 GB
Bandwidth
102 GB/s
Largest model
DeciLM 6B
Quadro K3100M carries only 4 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 3.6 GB.
Memory bandwidth reaches 102 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.
That comes from a memory clock of 800 MHz. It is why core counts predict generation speed so poorly.
The biggest thing it holds is DeciLM 6B, 5.7B, compressed to Q3_K_M and generating around 17.5 tokens per second.
The chip and how it was built
Quadro K3100M is built on the graphics processor GK104, using the architecture Kepler from NVIDIA, as part of the generation Quadro Kepler-M(Kx100M).
The chip is manufactured by TSMC, on a process of 28 nm, with a die measuring 294 mm², holding 3.5 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 July 2013, roughly 13.144355359556 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
45.2 GFLOPS
Double-precision throughput reaches 45.2 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 a base of 706 MHz to a boost of 706 MHz. 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 K3100M has an L1 cache of 16 KB, backed by an L2 cache of 0.5 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 768 shading units, 64 texture mapping units, and 32 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
75 W
Quadro K3100M is rated at 75 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 mxm module. 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 MXM-B (3.0). 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 Quadro K3100M
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
The table lists 105 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
Match the context to your work
Set the context to your real working length. Short questions cost almost nothing, but a long document can consume a large share of 4 GB so the setting is worth getting right.
-
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
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 43.3 tok/s on Gemma 4 E2B. The same card and model vary by thirty to fifty per cent between inference runtimes.
-
05
Read the fit verdict last
The fit column separates models that just fit from those with room to spare — worth checking before settling on one, against an available 4 GB.

Answers
Quadro K3100M — common questions
Quadro K3100M— what is the largest AI model it can run?
The largest model in our catalogue that fits is DeciLM 6B at 5.7B parameters, compressed to Q3_K_M. It generates roughly 17.5 tokens per second and needs about 3.5 GB of the card's memory.
Quadro K3100M— how many tokens per second does it produce?
It depends on the model. The fastest model we track here is Gemma 4 E2B at about 43.3 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 K3100M— how much memory does it have?
This card has 4 GB of GDDR5. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 3.6 GB available for a model and its conversation.
Quadro K3100M— what is its memory bandwidth?
Memory bandwidth reaches 102 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 K3100M— what type of memory does it use?
It uses GDDR5 clocked at 800 MHz. 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 K3100M— who makes it?
This is a product of NVIDIA, with the chip manufactured by TSMC, on a process of 28 nm.
Quadro K3100M— when was it released?
It was released in July 2013.
Quadro K3100M— how much power does it use?
Rated board power is 75 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 K3100M— how much cache does it have?
The L1 cache is 16 KB, and the L2 cache is 0.5 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 K3100M— does it support CUDA?
Yes. It reports CUDA compute capability 3.0, 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 K3100M— what bus interface does it use?
It uses MXM-B (3.0). 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 K3100M— 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 105 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Quadro K3100M— can it run a model that does not fit in its memory?
Offloading past the card's 4 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
Would two Quadro K3100M cards be twice as fast?
Pairing them buys headroom rather than pace: 8 GB of combined memory, at roughly the same generation speed as one.
Quadro K3100M— which AI models can it run?
105 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.
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.
