Geforce GTX 690 vs Radeon HD 7970

Intro

The Geforce GTX 690 uses a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 RAM works at a frequency of 1502 MHz on this specific model. It features 1536 SPUs along with 128 TAUs and 32 ROPs.

Compare those specs to the Radeon HD 7970, which makes use of a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this specific card. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

(No game benchmarks for this combination yet.)

Radeon HD 7970 118400 Mtexels/sec
Difference: 115840 (98%)

Pixel Rate

The Geforce GTX 690 should be much (about 98%) faster with regards to full screen anti-aliasing than the Radeon HD 7970, and able to handle higher screen resolutions without losing too much performance. (explain)

Geforce GTX 690 58560 Mpixels/sec
Radeon HD 7970 29600 Mpixels/sec
Difference: 28960 (98%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

@ homepage 7970 placed on top but here 690 kicked 7970.why inaccurate details in homepage
po says:
On the front page it's got the exact same memory bandwidth as the GTX680, meaning they were only running the dual core GTX690 in single core mode, while the 7970 was using both cores for the result on the front page.

GTX 690 blew 7970 away. But, GTX 690 is also 1 thousand dollars, while the 7970 is around 500 dollars. So, the question is, do you want to spend a bunch of money for the best video card or spend half that money for, I think, the second or third best video card?
Z9 says:
couze 690's big price a HD 7970 will be much better....but if you try to over lock at 1550 the memory HD 7970 will be almost equal at fps...with a difference of 10-20 fps...
I don't think it's worth to give 500 dollars more....for 10-20 fps.
thatkid1995 says:
if you have enough money to buy even one 690 then seriously can we trade lives?
And pcpp recommend TWO in SLI as their beast :)
TOO MUCH AWESOME!!!
Lucas says:
7990 will detonate 690

The 7970 x2 was announced... It's basically 2 7970's in a dual card gpu. It's about time AMD got some dual card gpu action going on.

john says:
It's kinda unfair, the GTX 690 Is a dual GPU, while the 7970 is just a single GPU, but given the price and the performance between the two, I certainly conclude that the Radeon was more better.
antonely93 says:
The GTX 690 is less powerful than the Powercolor Devil 13. with 2 GPU HD 7990! a ha!
AMDPC gamer says:
This comparison is not equal as the 7970 is not ATi's top card. The new ATi Radeon HD7990 would kill a GTX 690 as would the much older HD6990.
Stefan says:
yeah 7990 will detonate 690
but 790 will detonate 7990
nVidia the best
Poorya says:
wow i love this graphic card
this is most complete graphic card in the world
just GTX 690 \m/
onizine says:
So many fools with money to burn really have no clue about cost to performance ratio. 5 Hundred dollars for what? you can barely tell the difference. But I guess it's one of macho things. well put that card up against the fire-pro series and see or directcu II.
Pantelos says:
just take 780 ti close to 690 perfomance and 600$ :)
