GeForce RTX 3050 6GB (Reference design)

Reference design · 6 GB · catalogue identifier rtx-3050-6gb-ref · last updated 2026-09-24

82 desktops in this database carry a verdict for the GeForce RTX 3050 6GB (Reference design): 50 fit with conditions, 31 do not fit (3 of these are estimates) and 1 is unverified. Estimated Conditions most often concern card length (50 desktops), card width (50) and power (50); for this card, its length is not published and its slot width is not published. Of the 31 desktops it does not fit, all 31 conflict with a half-height-only slot; the Dell OptiPlex 3090 Small Form Factor (2021) is one of the 31. Estimated Among the 13 cards with 6 GB in this database, its board power of 70 W is the lowest of the group (70–250 W); its length is not published, while 5 cards in the group publish 168–267 mm. Estimated The largest listed model its 6 GB holds at 32k context is Qwen3 1.7B (Q4_K_M, needs 5.6 GiB). Estimated

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.

Desktops that take a card of this design

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: 50
  • ✕ Does not fit: 31 (3 of these are estimates) Estimated
  • ? Unverified: 1

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.

  1. Card length: the length of this card is not published. Check it on the specification of the card you intend to buy. (50 desktops)
  2. Card length: where a desktop publishes no maximum, measure the clearance in front of the slot and compare it with the card. (36 desktops)
  3. Card width: the number of slot positions this card occupies is not published. Check it on the specification of the card you intend to buy. (50 desktops)
  4. Card width: where a desktop publishes no slot-width ceiling, check that there is room beside the x16 slot. (48 desktops)
  5. Bracket height: this card is a full-height card. Bracket height: where a desktop's manufacturer does not state whether it takes only half-height cards, check the slot opening. (7 desktops)
  6. Bracket height: where a row says whether a desktop takes only half-height cards is recorded from third-party or community material, or from material whose source the record does not identify, rather than from a statement by the manufacturer, check the slot opening. (2 desktops)
  7. Power: where a row says a desktop's supply rating is recorded from third-party or community material, or from material whose source the record does not identify, rather than from a specification the manufacturer publishes, read the rating off the label on the supply in the machine you own. (50 desktops)

△ Fits with conditions 50 desktops:

✕ Does not fit 31 desktops, grouped by the published limit that conflicts with this card's published figures:

? Unverified 1 desktop. The evidence does not settle it either way, which is not the same as it 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.

Qwen3 4B Q4_K_M △ Fits at short context only 7.9 GiB 6 GB of memory covers the 3.9 GB required at a context length of 4,096 tokens, but not the 7.9 GB required at 32,768 tokens. B

✕ Exceeds VRAM 14 models need more memory at 32k context than this card has, 6 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.
