GeForce GTX Titan vs Radeon HD 7970

Intro

The GeForce GTX Titan uses a 28 nm design. nVidia has clocked the core frequency at 837 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific card. It features 2688 SPUs as well as 224 TAUs and 48 Rasterization Operator Units.

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 speed of 1375 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan will be 9% quicker than the Radeon HD 7970 in general, because of its greater bandwidth. (explain)

GeForce GTX Titan 288384 MB/sec
Radeon HD 7970 264000 MB/sec
Difference: 24384 (9%)

Texel Rate

The GeForce GTX Titan is quite a bit (approximately 58%) better at anisotropic filtering than the Radeon HD 7970. (explain)

GeForce GTX Titan 187488 Mtexels/sec
Radeon HD 7970 118400 Mtexels/sec
Difference: 69088 (58%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX Titan is a better choice, and very much so. (explain)

GeForce GTX Titan 40176 Mpixels/sec
Radeon HD 7970 29600 Mpixels/sec
Difference: 10576 (36%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.

Performance of titan is not worth the price... 7970 is 25% cheaper....

Tommy says:

ups... sorry... 7970 is 75% cheaper then titan :/ OMG!

Tom says:

both same ish, but this only shows AMD last gen gpu vs NVidia new gen gpu, if u put ATI/AMD HD 7990 vs titan u will see amd wins again, AMD always win in the GPU race, AMD for my GFX and INTEL for my CPU, ati ein again, but each month both ati/amd and nvidia will out do each other so for an amount of time each will be on top

Dillon says:

Just get 2 7970s, and there's something that would pack a punch. Maybe even harder than the titan, and save 200$.. Always have been a AMD fan, and always will be. AMD FTW.

David says:

Ok, TITAN's price is worth it, having in mind that its technologies are much more advanced than those of AMD, also it has lots of power at lower power conssumption than AMD. After that, for that who said that AMD 7990 beats TITAN, of course it does, but because it has 2 processors, while TITAN just has 1 and still competes against it, blabber mouth. Anyways 7990 6GB's can't beat TITAN also because of its single CrossFire mode for up to 12GB on 2 GPUs, while TITAN beats that with ease at 24GB on Quad-SLI configuraction and can beat any GPU nowadays also due to this and much more. And a final detail, AMD just works on gaming, while nVidia works on gaming and also for more demanding design software, like Adobe and AutoDesk, due to the integration of kepler technology as on its industrial GPUs, Quadro and Tesla.

James Adkins says:

two 7970s are about $500 used on ebay right now, that is about half the price of a titan and almost 175% performance
