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
12 GB
Bandwidth
456 GB/s
Largest model
ERNIE-4.5-21B-A3B
12 GB of GDDR6 puts the Arc B580 comfortably into small and mid-sized models, with roughly 10.8 GB usable once the driver overhead is taken out. The largest models are out of reach without splitting them.
The memory bus moves 456 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.
That comes from a 2.38 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.
In practice that combination tops out at ERNIE-4.5-21B-A3B — 21B, compressed to Q3_K_M, generating around 89.6 tokens per second.
The chip and how it was built
The Arc B580 is built on the BMG-G21 graphics processor, using Intel's Xe2-HPG architecture, as part of the Battlemage(Arc 5) generation.
The chip is manufactured by TSMC, on a 5 nm process, with a die measuring 272 mm², holding 19.6 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 December 2024, roughly 1 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
27.3 TFLOPS
FP64
1.7 TFLOPS
On paper the Arc B580 reaches 27.3 TFLOPS at half precision and 13.7 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 1.7 TFLOPS. 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 2.67 GHz at base to 2.67 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 Arc B580 has 250 KB of L1 cache, backed by 18 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 2,560 shading units, 160 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
190 W
The Arc B580 is rated at 190 W, with a 450 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 272 mm long, and needs 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 4.0 x8. 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 Arc B580
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 396 models this Arc B580 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; a long document can consume a large share of the card's 12 GB.
-
03
Pin the comparison to one quality level
By default the table picks the least-compressed copy that fits. Setting a floor removes models that only qualify through heavy compression.
-
04
Take the range as the answer
Speeds come with error bars for a reason. The best case here is 126 tok/s on Gemma 3 QAT 1B, and which inference software you use moves that by thirty to fifty per cent.
-
05
Read the fit verdict last
Compare what each model needs with the 12 GB this card provides. Tight means it works today; comfortable means it still works when the conversation grows.

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 Arc B580 compares.
Answers
Arc B580 — common questions
What is the memory bandwidth of a Arc B580?
The Arc B580 has 456 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 Arc B580 use?
It uses GDDR6 clocked at 2.38 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 Arc B580?
The Arc B580 is a Intel product, with the chip manufactured by TSMC, on a 5 nm process.
When was the Arc B580 released?
The Arc B580 was released in December 2024.
How much power does a Arc B580 use?
The Arc B580 has a rated board power of 190 W, and a 450 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 Arc B580 have?
The Arc B580 has 250 KB of L1 cache, and 18 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 Arc B580?
The Arc B580 is rated at 27.3 TFLOPS at half precision and 13.7 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.
Does the Arc B580 support CUDA?
No. CUDA is NVIDIA-only, and the Arc B580 is a Intel card. It runs language models through ROCm, Vulkan or Metal depending on the software, which are less mature than the CUDA path — our estimates apply a penalty for that.
What bus interface does the Arc B580 use?
It uses PCIe 4.0 x8. 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 Arc B580 good for running local AI models?
Its memory covers small and mid-sized models, though the largest are out of reach and its bandwidth gives usable, if unspectacular, generation speeds. In total it runs 396 of the models we track. Whether that is enough depends entirely on which model you want — the table above answers that directly.
Can a Arc B580 run a model that does not fit in its memory?
Offloading past the card's 12 GB is possible and usually a false economy: the system-memory portion is slow enough to dominate the result.
Would two Arc B580 cards be twice as fast?
No. A second Arc B580 doubles the memory to 24 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 Arc B580 run?
396 of the 679 open-weight language models we track fit on a Arc B580 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 Arc B580 can run?
The largest model in our catalogue that fits on a Arc B580 is ERNIE-4.5-21B-A3B at 21B parameters, compressed to Q3_K_M. It generates roughly 89.6 tokens per second and needs about 10.1 GB of the card's memory.
How many tokens per second does a Arc B580 produce?
It depends on the model. On a Arc B580 the fastest model we track is Gemma 3 QAT 1B at about 126 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 Arc B580 run a 7B model?
Yes. For example a Arc B580 runs DeepSeek Coder 6.7B at Q6_K, using about 9.9 GB of memory and generating around 27.2 tokens per second.
Can a Arc B580 run a 13B model?
Yes. For example a Arc B580 runs DeepSeekMoE-16B at Q4_K_M, using about 10.0 GB of memory and generating around 101 tokens per second.
How much memory does a Arc B580 have?
A Arc B580 has 12 GB of GDDR6 memory. Around a tenth of that is reserved by the inference runtime and the driver, leaving roughly 10.8 GB available for a model and its conversation.
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.
