Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.

15 Responses to “Radeon HD 7970 vs Radeon R9 280X”That's interesting. If 280x more slowly than 7970, why is it called better than 7970 ghz edition ?
I hope that you know Hardware comparison is wrong ah?
This is all hypothetical since it's all specs and not actual benchmarks. Honestly the 7970 GHz and most of the 280x models are exactly the same in performance.
Not exactly ... the 7970 GHz is a little bit faster, but the r9 280's price is much lower.
these stats are wrong... the base clock of the 280x is like a power saving mode, not to be used in gaming. the 280x is, when being used on the gaming clock speeds better in every way than a HD7970.
of course its only a bit better because it is just a HD7970 with clock speeds increased but thats beside the point.
amd price goughing, thats really nice
7970 practically the same hardware with a 280x
consumers are so stupid, i expected better from computer nerds but im wrong
even with nvidia people have been taking it in the ass ever since
go amd milk everybody's tits, thats the way its been done, learn from your arch nemesis
The only diference between R9 280X and HD 7970 is the package.
I do want to point out the clock speed on here are wrong, by quite a lot and this website doesn't include the 7970 ghz edition.
The normal clock speeds of a r9 280x are 1100 (1150 with boost) core and 1600 (6400 effective) memory speed.
Well, many sites have done a comprehensive, side-by-side comparison test on these two cards. It's no secret they have the same gpu architecture - with the 280x being a little better in power efficiency under full load. The 280x is simply a rebranded (and supposedly reworked) Tahiti core. If you've got the 7970, you can also xf it with a 280x. If you're looking to upgrade from lesser cards, try looking around for a cheaper, 2nd hand 7970, as it slightly outperforms the 280x in most 3D gaming scenarios.
7950 will also crossfire with the 280x. Just as the 7970 and 7950 will crossfire. Work's very well indeed.
ya pero no sale la MSI Radeon R9 280X Gaming ((6GB)) GDDR5
la comparacion cambiaria creo yo aun que no demasiado pero si se notaria sobretodo en los filtros no?
sooo much wrong knowings about this subject.... its simple, the amd HD 7970 is older, the r9 280x is newer. the r9 280x is just an amd hd 7970, but its newer so its slightly faster. same hardware, same chip ( tahiti ) same memory. one thing is wrong here, i have the r9 280x vapor-x and it doesnt has 850mhz, it has 1050 mhz at default clock speed.... so yea, the r9 280x is better but depends on which one you buy! the msi one or the vapor-x? there's a huge different.
better said: R9 280x is better in every single way of use compared to the HD series ( not talking about the dual-core gpu's )
this is not correct!!! look on GPU BOSS,this website is bullshitt!!! R9 280X is better than 7970
the only difference is
7970 pcie 2.1
r9 280x pcie 3.0

hehe i dont care
