GeForce 9800 GTX vs Radeon HD 3870 1GB

Intro

The GeForce 9800 GTX features a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specifications to the Radeon HD 3870 1GB, which comes with GPU clock speed of 775 MHz, and 1024 MB of GDDR4 memory set to run at 1125 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 3870 1GB 106 Watts
GeForce 9800 GTX 140 Watts
Difference: 34 Watts (32%)

Memory Bandwidth

The Radeon HD 3870 1GB should in theory be a small bit faster than the GeForce 9800 GTX in general. (explain)

Radeon HD 3870 1GB 72000 MB/sec
GeForce 9800 GTX 70400 MB/sec
Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX should be a lot (approximately 248%) more effective at AF than the Radeon HD 3870 1GB. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon HD 3870 1GB 12400 Mtexels/sec
Difference: 30800 (248%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 3870 1GB is the winner, but it probably won't make a huge difference. (explain)

Radeon HD 3870 1GB 12400 Mpixels/sec
GeForce 9800 GTX 10800 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better 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 are processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the 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 the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
