Geforce GTX 690 vs Radeon HD 7970


The Geforce GTX 690 features a clock speed of 915 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 256-bit memory bus, and uses a 28 nm design. It features 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 7970, which features GPU clock speed of 925 MHz, and 3072 MB of GDDR5 RAM running at 1375 MHz through a 384-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7970 250 Watts
Geforce GTX 690 300 Watts
Difference: 50 Watts (20%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 690 is 46% quicker than the Radeon HD 7970 overall, because of its greater bandwidth. (explain)

Geforce GTX 690 384512 MB/sec
Radeon HD 7970 264000 MB/sec
Difference: 120512 (46%)

Texel Rate

The Geforce GTX 690 should be quite a bit (more or less 98%) faster with regards to anisotropic filtering than the Radeon HD 7970. (explain)

Geforce GTX 690 234240 Mtexels/sec
Radeon HD 7970 118400 Mtexels/sec
Difference: 115840 (98%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 690 is a better choice, and very much so. (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 largest amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 can be applied per second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max 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.

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 :)

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$ :)
