Clocks

1 of 5 differ

Base clockiLowest rated clock under load that the card maker states for this card in MHz. NVIDIA's base clock in GHz is a chip value, and a figure such as 2.33 GHz gives no exact MHz value, so it is not converted. A row labelled only "Clock Speed" next to a boost clock row, as on PNY, is the base clock. On an NVIDIA card, a row labelled Graphics Clock next to a Boost Clock row, as on Palit, is the base clock too. A retail or distributor feed that repeats NVIDIA's reference base clock does not count. A card maker's own page that states the reference base clock for a card at reference clocks counts.

Not available

Not available

Game clockiAMD Game Clock or Intel Graphics Clock of this card. Both are a typical clock in games, below the peak boost. On an Intel card, a card maker figure labelled Graphics Clock or Engine Clock is this clock, also with "up to". A figure the card maker labels Boost Clock stays a boost clock.

Boost clockiRated boost clock of this card out of the box, e.g. ASUS "Default mode" or MSI "Boost". Not a measured clock, the OC mode clock or another card's rating. AMD's boost clock is a maximum burst clock. NVIDIA's is its rated boost clock. Compare within one chip maker only. When the card ships in its OC BIOS position, as the PowerColor Hellhound does, that BIOS clock is stored here and the OC mode field stays empty. The other BIOS clock goes in the source note.

Upscaling technologiesiThe maker's upscaling names with version, e.g. "DLSS 4", "FSR 4", "XeSS 2". Game support varies. A bundle name such as FSR Redstone is not an upscaler name, so its upscaler is written with its version, such as FSR 4. When the card maker and the chip maker write different versions, the chip maker's spec table wins. When the chip maker names no version, as NVIDIA writes DLSS for RTX 30 cards, the name is stored without one.

Power

1 of 4 differ

Board poweriDefault board power or power limit of this card. Use the card maker's figure first: NVIDIA Total Graphics Power, AMD Total or Typical Board Power, Intel TBP. A row on the card maker's own page counts under any label, such as Power Consumption or TDP. When the card maker states none, a reviewer's reading of the default power limit counts, and the source note names the reader and the tool. Retail feed fields such as "Power consumption (typical)" do not count. AMD's Typical Board Power and the power limit can differ. When both are known, store the default-mode power limit. The reference figure is not proof of a partner card's power. Other BIOS modes go in the source note. A reviewer who only relays a maker figure has not read the power limit.

Makers differ for the same GPU, so compare cards of one maker only.

Dimensions and weight

4 of 8 differ

LengthiCard length along the PCIe connector, from the bracket to the far end. Makers write it as L. Makers write L x W x H. W is the card height and H is the thickness. NVIDIA calls the height Width. Retail feeds relabel the sides as Height, Width or Depth, so decide by size: length is the longest side and thickness the shortest. When the maker lists sizes with and without the bracket, store the size with the bracket.

Slot widthiThickness in expansion-slot units as the card maker states it, e.g. 2.5 or 3.125. Not the number of slots the card covers in a case. Only a slot figure the card maker states. Do not compute it from the thickness. Retail feeds give different values for the same card. A slot figure in a row labelled Height, as on Palit, counts.

NVIDIA SFF-ReadyiThe card is on NVIDIA's SFF-Ready Enthusiast GeForce list. Only GeForce cards can qualify. For a GPU class the list covers, the list decides, and a card missing from it is false.

Package weightiOne retail box with its contents. A weight rounded to whole kilograms in a retail or distributor feed is not stored. A feed weight that does not say whether it is the card or the package is not stored. A feed's gross weight is the package weight, and the same rounding rule applies.
