Hi,

I can't find the post where somebody said what the "9" meant in GTX790. Or any Nvida graphic card for that matter.


I know the 7 is the series card model but I cant remember the ranges from a 5-9.

Can you guys help?

Thank you

-90 usually indicates that it is a dual-GPU card. The GTX 690, for example, has two of the same GPU as the GTX 680 uses.

In Nvidia's nomenclature, the first digit is the generation. So this, latest generation cards are labelled "7xx", and the revision before were "6xx", and generation before "5xx" and so on so forth.

The second digit is the tier of card. For instance, the 780 is essentially the top tier of card in this generation. With the 770 being slightly slower, the 760 slower still and again, so on so forth.

With each generation there are slight changes either way, in that there may be something architecturally that's radically different between two cards;

For instance, the Nvidia 770 is essentially a rename of the 680. Exactly the same board, same chip, same everything (apart from clock speeds, which have been increased). Whereas the 780 is based on a different chip altogether, based on the chip used inside the Titan.

In layman's terms, the higher the number, the faster the card. Not always the case, but this is true in most cases.

it simple terms the 790 was the naming for nvidia two gpu on a card naming. the x80 was the top line gpu. (with nvidia the cut the number of there cuda cours as you go down in nuber and they change the gpu that used). keplar 110 is used on the top end. then there the 107 and 104 cut down of the same 110 card.

Thanks houldendub,

Do you have a source on where I can find a generalized standard for these digits? (Eg. x5x is entry level, x6x mid range card, x7x, high end, x9x- top of the line tier)

There is no absolute standard. They fiddle with the naming scheme over time. For example, the multi-GPU cards used to be indicated by a -95 (as in the GTX 295), but now it's just -90.

790 is probably going to be a dual GPU card 2x 780s.
you can compare it to amd with their naming in the past for the 7990. which was 2 7970s I think

In short all 9 means it's bigger than 8

790 > 780 > 770 > 760 > 750

The 9s for the most part have been 2 GPU cards.

Don't put to much into it ..... the numbers are very shall we say "flexible"..... the tweaked 670 becomes the 760 the following year .... the 680 becomes the 770.

It was widely suggested that with the 6xx launch, the original 680 was never released......thinking went as the original 670 was faster than the 7970, they relabeled the 670 as the 680 and put the original 680 "on the shelf"

As someone else mentioned, there's not a strict standardisation, the meaning of the numbers can change each generation.

Actually, one of the best tools to use to see what each card loosely compares to is found right here on this very site:

Not an exact chart, but it's a very good place to start.

There's also the GPU database at TechPowerUp for in-depth info, or Wikipedia of course.
