GeForce 9800 GTX vs Radeon HD 5750 1GB

Intro

The GeForce 9800 GTX features clock speeds of 675 MHz on the GPU, and 1100 MHz on the 512 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Compare those specs to the Radeon HD 5750 1GB, which comes with clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB 86 Watts
GeForce 9800 GTX 140 Watts
Difference: 54 Watts (63%)

Memory Bandwidth

The Radeon HD 5750 1GB should theoretically perform a small bit faster than the GeForce 9800 GTX overall. (explain)

Radeon HD 5750 1GB 73600 MB/sec
GeForce 9800 GTX 70400 MB/sec
Difference: 3200 (5%)

Texel Rate

The GeForce 9800 GTX will be quite a bit (approximately 71%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 18000 (71%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is the winner, though not by far. (explain)

Radeon HD 5750 1GB 11200 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 400 (4%)

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 transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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