GeForce GTS 250 512MB vs Radeon HD 5750 1GB

Intro

The GeForce GTS 250 512MB features a clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare those specifications to the Radeon HD 5750 1GB, which makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 memory is set to run at a frequency of 1150 MHz on this model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 ROPs.

Radeon HD 5750 1GB 73600 MB/sec
GeForce GTS 250 512MB 70400 MB/sec
Difference: 3200 (5%)

Texel Rate

The GeForce GTS 250 512MB is quite a bit (more or less 87%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTS 250 512MB 47232 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 22032 (87%)

Pixel Rate

The GeForce GTS 250 512MB should be a bit (more or less 5%) more effective at full screen anti-aliasing than the Radeon HD 5750 1GB, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTS 250 512MB 11808 Mpixels/sec
Radeon HD 5750 1GB 11200 Mpixels/sec
Difference: 608 (5%)

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 largest amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
