GeForce GTX 470 vs Radeon HD 6970


Intro

The GeForce GTX 470 features a clock speed of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It features 448 SPUs, 56 TAUs, and 40 ROPs.

Compare those specs to the Radeon HD 6970, which has clock speeds of 880 MHz on the GPU, and 1375 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth

The Radeon HD 6970 should in theory perform quite a bit faster than the GeForce GTX 470 in general. (explain)

Radeon HD 6970 176000 MB/sec
GeForce GTX 470 133920 MB/sec
Difference: 42080 (31%)

Texel Rate

The Radeon HD 6970 is much (about 149%) more effective at anisotropic filtering than the GeForce GTX 470. (explain)

Radeon HD 6970 84480 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 50488 (149%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 6970 is superior to the GeForce GTX 470, but it probably won't make a huge difference. (explain)

Radeon HD 6970 28160 Mpixels/sec
GeForce GTX 470 24280 Mpixels/sec
Difference: 3880 (16%)

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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.

Just a tip to all guys who wrote HD 6970 VS GTX 470.....WHY THE FUCK DID U ASK SO IDIOT QUESTIONS???....HD 6970 is much better than GTX 470,and even it was just a bit all we know GTX 470 can reach about 105-110+
thing which isn't cool!!!!

Hell what are you talking about? not everyone knows all the manufacturers designations by heart!

Also, try to write in understandable english when posting on the web, or just stop it, because your comments aren't productive in any way
