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
24 GB
Bandwidth
300 GB/s
Largest model
Mixtral 8x7B
The L4 carries 24 GB of GDDR6, 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.
The memory bus moves 300 GB/s across a 192-bit bus. That is the number that governs generation speed — arithmetic per byte read is small enough that the bus, not the cores, is what everything waits on.
Bandwidth is clock times bus width, and this card clocks its memory at 1.56 GHz. Both halves matter, and neither is visible in a gaming benchmark.
The biggest thing it holds is Mixtral 8x7B (46.7B) at Q3_K_M compression, for about 26.6 tokens per second.
The chip and how it was built
The L4 is built on the AD104 graphics processor, using NVIDIA's Ada Lovelace architecture, as part of the Server Ada(Lxx) generation.
The chip is manufactured by TSMC, on a 5 nm process, with a die measuring 294 mm², holding 35.8 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 March 2023, roughly 3 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
30.3 TFLOPS
FP64
473.3 GFLOPS
Tensor cores
240
On paper the L4 reaches 30.3 TFLOPS at half precision and 30.3 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 is 473.3 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 240 tensor cores across 60 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 795 MHz at base to 2.04 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 L4 has 128 KB of L1 cache, backed by 48 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 7,424 shading units, 240 texture mapping units, and 80 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
72 W
The L4 is rated at 72 W, with a 250 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 single-slot, measuring 169 mm long. 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.

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 L4
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
Every one of the 502 models this L4 runs is in the table above. Search narrows it by name or by size.
-
02
Decide how long your conversations run
Set the context to your real working length. Short questions cost almost nothing; a long document can consume a large share of the card's 24 GB.
-
03
Choose how far you will compress
By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.
-
04
Read the speed and the range
Each speed is an estimate for a single conversation, with a range beneath it — 127 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
The fit column separates models that just fit from those with room to spare — worth checking against the card's 24 GB before settling on one.
-
06
Check the same model from the other side
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 L4 compares.
Answers
L4 — common questions
Can a L4 run a model that does not fit in its memory?
It can be split, with the overflow held in system memory — but that part drags the whole thing down, and none of the 24 GB figures on this page assume it.
Would two L4 cards be twice as fast?
Pairing L4 cards buys headroom rather than pace: 48 GB of combined memory, at roughly the same generation speed as one.
What AI models can a L4 run?
502 of the 679 open-weight language models we track fit on a L4 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 L4 can run?
The largest model in our catalogue that fits on a L4 is Mixtral 8x7B at 46.7B parameters, compressed to Q3_K_M. It generates roughly 26.6 tokens per second and needs about 21.0 GB of the card's memory.
How many tokens per second does a L4 produce?
It depends on the model. On a L4 the fastest model we track is Gemma 3 QAT 1B at about 127 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 L4 run a 7B model?
Yes. For example a L4 runs Multi-Token Prediction 7B at Q8_0, using about 7.9 GB of memory and generating around 19.0 tokens per second.
Can a L4 run a 13B model?
Yes. For example a L4 runs DeepSeekMoE-16B at Q8_0, using about 17.5 GB of memory and generating around 44.1 tokens per second.
Can a L4 run a 30B model?
Yes. For example a L4 runs Nemotron 3-Nano-30B-A3B at Q4_K_M, using about 18.1 GB of memory and generating around 51.6 tokens per second.
How much memory does a L4 have?
A L4 has 24 GB of GDDR6 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 L4?
The L4 has 300 GB/s of memory bandwidth, across a 192-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 L4 use?
It uses GDDR6 clocked at 1.56 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 L4?
The L4 is a NVIDIA product, with the chip manufactured by TSMC, on a 5 nm process.
When was the L4 released?
The L4 was released in March 2023.
How much power does a L4 use?
The L4 has a rated board power of 72 W, and a 250 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 L4 have?
The L4 has 128 KB of L1 cache, and 48 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 L4?
The L4 is rated at 30.3 TFLOPS at half precision and 30.3 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.
How many tensor cores does a L4 have?
The L4 has 240 tensor cores across 60 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 L4 support CUDA?
Yes. The L4 reports CUDA compute capability 8.9. 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 L4 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 L4 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.
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.
