GeForce 9600 GSO 512MB vs Radeon HD 4770

Intro

The GeForce 9600 GSO 512MB uses a 65/55 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 48 TAUs and 16 ROPs.

Compare all that to the Radeon HD 4770, which uses a 40 nm design. AMD has set the core frequency at 750 MHz. The GDDR5 memory is set to run at a speed of 800 MHz on this specific model. It features 640(128x5) SPUs along with 32 TAUs and 16 Rasterization Operator Units.

GeForce 9600 GSO 512MB 57600 MB/sec
Radeon HD 4770 51200 MB/sec
Difference: 6400 (13%)

Texel Rate

The GeForce 9600 GSO 512MB should be quite a bit (approximately 30%) more effective at texture filtering than the Radeon HD 4770. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
Radeon HD 4770 24000 Mtexels/sec
Difference: 7200 (30%)

Pixel Rate

The Radeon HD 4770 should be just a bit (more or less 15%) more effective at full screen anti-aliasing than the GeForce 9600 GSO 512MB, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 4770 12000 Mpixels/sec
GeForce 9600 GSO 512MB 10400 Mpixels/sec
Difference: 1600 (15%)

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 max amount of data (in units of MB per second) that can be transported across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
