VS

GeForce 9800 GTX vs Radeon HD 5750 1GB

Intro

The GeForce 9800 GTX has core 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 Rasterization Operator Units.

Compare that to the Radeon HD 5750 1GB, which has GPU core speed of 700 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

GeForce 9800 GTX 70400 MB/sec
Difference: 3200 (5%)

Texel Rate

The GeForce 9800 GTX will be a lot (more or less 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 using a high screen resolution is important to you, then the Radeon HD 5750 1GB is superior to the GeForce 9800 GTX, but only just. (explain)

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
