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

What the memory subsystem means for AI

Memory

8 GB

Bandwidth

68 GB/s

Largest model

Baichuan 1-13B

H3C XG310 carries only 8 GB of LPDDR4X. 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 68 GB/s across a bus of 128 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 2.13 GHz. Both halves matter, and neither is visible in a gaming benchmark.

In practice that combination tops out at Baichuan 1-13B, 13.3B, compressed to Q3_K_M and generating around 3.8 tokens per second.

The chip and how it was built

H3C XG310 is built on the graphics processor DG1, using the architecture Generation 12.1 from Intel, as part of the generation H3C Graphics.

The chip is manufactured by Intel, on a process of 10 nm, with a die measuring 95 mm². 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 2020, roughly 5.8404585442809 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

3.4 TFLOPS

FP64

422.4 GFLOPS

On paper H3C XG310 reaches 3.4 TFLOPS at half precision, and 1.7 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 reaches 422.4 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 1.05 GHz to a boost of 1.1 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

backed by an L2 cache of 1 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, 48 texture mapping units, and 24 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

300 W

H3C XG310 is rated at 300 W, and the suggested system power supply is 700 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, 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 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.

Step by step

How to work out the tokens per second of a H3C XG310

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.

  1. 01

    Start with the model, not the specification

    The table lists 351 models the card handles. The search box takes a name or a size such as 27b, which matches on parameter count.

  2. 02

    Match the context to your work

    Drag the slider to the conversation length you plan to work at. The cache grows with the conversation, and against a card holding 8 GB that is frequently the difference between a model fitting and not.

  3. 03

    Set a minimum quality if you need one

    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.

  4. 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 18.8 tok/s on Gemma 3 QAT 1B. The same card and model vary by thirty to fifty per cent between inference runtimes.

  5. 05

    Check the memory column before committing

    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 an available 8 GB.

  6. 06

    Cross-check against other hardware

    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 H3C XG310.

Answers

H3C XG310 — common questions

01

H3C XG310— how much memory does it have?

This card has 8 GB of LPDDR4X. Around a tenth is reserved by the inference runtime and the driver, leaving roughly 7.2 GB available for a model and its conversation.

02

H3C XG310— what is its memory bandwidth?

Memory bandwidth reaches 68 GB/s across a bus of 128 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.

03

H3C XG310— what type of memory does it use?

It uses LPDDR4X clocked at 2.13 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.

04

H3C XG310— who makes it?

This is a product of Intel, with the chip manufactured by Intel, on a process of 10 nm.

05

H3C XG310— when was it released?

It was released in November 2020.

06

H3C XG310— how much power does it use?

Rated board power is 300 W, and the suggested system power supply is 700 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.

07

H3C XG310— how much cache does it have?

and the L2 cache is 1 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.

08

H3C XG310— what are its TFLOPS?

It is rated at 3.4 TFLOPS at half precision and 1.7 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.

09

H3C XG310— does it support CUDA?

No. CUDA is NVIDIA-only, and this is a card from Intel. 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.

10

H3C XG310— 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.

11

H3C XG310— 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.

12

H3C XG310— can it run a model that does not fit in its memory?

Offloading past the card's 8 GB drags the whole thing down, and none of the figures on this page assume it.

13

Would two H3C XG310 cards be twice as fast?

No. A second card doubles the memory to 16 GB which lets you hold models neither could hold alone, but generation does not split that way. These figures describe one card.

14

H3C XG310— 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.

15

H3C XG310— 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 3.8 tokens per second and needs about 7.2 GB of the card's memory.

16

H3C XG310— 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 18.8 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.

17

H3C XG310— 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 7.5 tokens per second.

18

H3C XG310— 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 4.2 tokens per second.

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.
