GeForce GTX 470 vs Radeon HD 5770


Intro

The GeForce GTX 470 has a GPU core clock speed of 607 MHz, and the 1280 MB of GDDR5 memory is set to run at 837 MHz through a 320-bit bus. It also features 448 SPUs, 56 TAUs, and 40 ROPs.

Compare all of that to the Radeon HD 5770, which uses a 40 nm design. AMD has clocked the core speed at 850 MHz. The GDDR5 memory is set to run at a frequency of 1200 MHz on this model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Radeon HD 5770 76800 MB/sec
Difference: 57120 (74%)

Texel Rate

The Radeon HD 5770 should be a small bit (more or less 0%) better at AF than the GeForce GTX 470. (explain)

Radeon HD 5770 34000 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 8 (0%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 470 is the winner, by far. (explain)

GeForce GTX 470 24280 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 10680 (79%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
