GeForce 9600 GSO 512MB vs Radeon HD 3870 512MB

Intro

The GeForce 9600 GSO 512MB has a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 96 SPUs, 48 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 3870 512MB, which features GPU clock speed of 775 MHz, and 512 MB of GDDR3 memory set to run at 900 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 512MB 90 Watts
Radeon HD 3870 512MB 106 Watts
Difference: 16 Watts (18%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce 9600 GSO 512MB should be a lot (more or less 152%) faster with regards to texture filtering than the Radeon HD 3870 512MB. (explain)

GeForce 9600 GSO 512MB 31200 Mtexels/sec
Radeon HD 3870 512MB 12400 Mtexels/sec
Difference: 18800 (152%)

Pixel Rate

The Radeon HD 3870 512MB is a small bit (about 19%) better at anti-aliasing than the GeForce 9600 GSO 512MB, and also capable of handling higher resolutions more effectively. (explain)

Radeon HD 3870 512MB 12400 Mpixels/sec
GeForce 9600 GSO 512MB 10400 Mpixels/sec
Difference: 2000 (19%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
