Intel Arc A770 (Reference design), 8 GB

Reference design · 8 GB · catalogue identifier arc-a770-8gb-ref · last updated 2026-09-24

82 desktops in this database carry a verdict for the Intel Arc A770 (Reference design), 8 GB: 48 do not fit (12 of these are estimates) and 34 are unverified. Estimated Of the 48 desktops it does not fit, 32 conflict with a half-height-only slot and 16 with the desktop's largest supply option; the Dell OptiPlex 3060 Small Form Factor (2018) is one of the 32. Estimated Among the 43 cards with 8 GB in this database, its board power of 225 W is within 50–295 W, with 35 lower and 4 higher; its length is not published, while 19 cards in the group publish 163–275 mm. Estimated The largest listed model its 8 GB holds at 32k context is Qwen3 4B (Q4_K_M, needs 7.9 GiB).

Published specifications for this design, the OEM desktops whose own specifications accept it, and how much of a local language model its memory holds.

We have not physically tested this combination. Data is compiled from official specification sheets and cited sources.

“Reference design” is a specification, not a product. The figures below are the ones the chip vendor publishes for a baseline board: board power, auxiliary power connector and recommended system power. Cards sold by board partners are built to their own designs and differ in length, height and cooler. This database does not claim that a card built to this exact design was sold at retail, and where the chip vendor does not publish a dimension, the row below says so.

Another entry in this database carries the same printed name. The two are distinguished here by memory size.

Power. Leave headroom; OEM PSUs are often rated at the limit. The recommended system figure above is the card vendor's own, and it assumes a retail supply rather than an OEM one.

Desktops that take a card of this design

No desktop in this database carries a fitting verdict for this card. It was assessed against 82 of them. Its published figures are inside the range that other cards clear here, so the conflict is with particular machines rather than with every one of them; each desktop's own page says what its specifications record.

This card has been assessed against 82 desktops in this database. Each verdict is a statement about published specifications, not about a tested combination.

  • ✓ Fits: 0
  • △ Fits with conditions: 0
  • ✕ Does not fit: 48 (12 of these are estimates) Estimated
  • ? Unverified: 34

✕ Does not fit 48 desktops, grouped by the published limit that conflicts with this card's published figures:

? Unverified 34 desktops. The evidence does not settle these either way, which is not the same as them being ruled out.

Verify with the manufacturer before purchasing.

What each verdict means. Every one of them is a statement about published specifications.
VerdictMeaning
✓ Fits Published specifications show no physical or electrical conflict.
△ Fits with conditions Published specifications allow it only under the stated conditions.
✕ Does not fit Published specifications rule the combination out: the card needs a connector the machine does not have, draws more than the supply provides, or is physically too large. It is a statement about specifications, not a report of a failed attempt.
? Unverified There is not enough evidence to say.

A dashed Estimated badge at the start of a line marks every verdict on that line as published as an estimate, and the grade beside it applies to each of them. The document behind each verdict, and the desktop's own figures, are listed on the desktop's own page. This card has a verdict for 82 of the 82 desktops in this database; the remaining 0 have not been assessed against it, which is not the same as them being ruled out.

Local language models this card's memory holds

Arithmetic shared by the models below. Sentences that read the same for more than one model are stated once here; each row names the ones it carries by number.

  1. This outcome is no stronger than the figures it was calculated from: the size of the model file that is distributed is recorded here from third-party or community material, so grade D is shown alongside B. (2 rows)
Calculated from the published file size and the model architecture.

This outcome is no stronger than the figures it was calculated from: the size of the model file that is distributed and this model's layer count and this model's key/value head count and this model's head dimension are recorded here from third-party or community material, so grade D is shown alongside B.

✕ Exceeds VRAM 12 models need more memory at 32k context than this card has, 5 of them published as an estimate. The arithmetic for each is on the model's own page.

Exceeds VRAM does not mean the model will not run: inference software can keep part of a model in system memory. How fast that is, and whether it is pleasant to use, is outside what this site measures. The sizing rule and its constants are on the Methodology page.

Cards whose published memory size is the same, so the local-model outcomes on this page apply to them as well. Whether a given desktop accepts them is a separate question, answered on each card's own page.
