AMD Radeon 520

Factory graphics option · 2 GB · catalogue identifier radeon-520-2gb · last updated 2026-09-24

10 desktops in this database carry a verdict for the AMD Radeon 520: 10 fit. Fits without conditions: the Lenovo ThinkCentre M70s, Lenovo ThinkCentre M70t, Lenovo ThinkCentre M720 Tower and 7 others. No listed model fits in its 2 GB at 32k context; the smallest, Gemma 3 4B, needs 4.7 GiB. Estimated

This is a factory option, not a card you can buy. A computer manufacturer lists it in its own specification sheet for a machine, exactly as “AMD Radeon 520”. The published specifications therefore record a card of this class as a factory option for that machine, but no card-level specification is published for the option itself, so this page carries no dimensions, no board power, no connector, and no purchase link.

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

Desktops whose verdicts reference this option

This card has been assessed against 10 desktops in this database. Each verdict is a statement about published specifications, not about a tested combination.

✓ Fits: 10
△ Fits with conditions: 0
✕ Does not fit: 0
? Unverified: 0

Conditions shared by the desktops below. Each is stated once here. They come from this card's own records, or are worded the same for more than one desktop. A desktop listed below names the ones it carries by number; the figures particular to that desktop are on its own page.

The manufacturer offers this card as a factory configuration for this model, so the chassis, the bracket and the supply are established by that shipping fact — for this model alone. The manufacturer's specification sheet gives no dimensions and no power draw for the card on its own, so the coverage requirement does not apply to it. (10 desktops)

✓ Fits 10 desktops:

confidence A (10): Lenovo ThinkCentre M70s [1], ThinkCentre M70t [1], ThinkCentre M720 Tower [1], ThinkCentre M75s [1], ThinkCentre M80s [1], ThinkCentre M80t [1], ThinkCentre M90s [1], ThinkCentre M90t [1], ThinkCentre M920 Small Form Factor [1], ThinkCentre M920 Tower [1]

What each verdict means. Every one of them is a statement about published specifications.
Verdict	Meaning
✓ 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 10 of the 82 desktops in this database; the remaining 72 have not been assessed against it, which is not the same as them being ruled out.

Local language models this card's memory holds

Calculated from the published file size and the model architecture.
Model	Outcome	Needs at 32k context	The arithmetic	Confidence
Qwen3 0.6B Q4_K_M	△ Fits at short context only Estimated	4.9 GiB	2 GB of memory covers the 1.9 GB required at a context length of 4,096 tokens, but not the 4.9 GB required at 32,768 tokens. This outcome is no stronger than the figures it was calculated from: this card's memory size is recorded here from material whose source the record does not identify, so grade E is shown alongside B.

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.
