GeForce 9800 GTX+ vs Radeon HD 5750 1GB

Intro

The GeForce 9800 GTX+ comes with a GPU clock speed of 738 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 5750 1GB, which features a core clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It features 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 1GB 86 Watts
GeForce 9800 GTX+ 145 Watts
Difference: 59 Watts (69%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5750 1GB should perform a little 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+ should be quite a bit (about 87%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce 9800 GTX+ 47232 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 22032 (87%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce 9800 GTX+ is a better choice, though not by far. (explain)

GeForce 9800 GTX+ 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 maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is 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 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

9800 GTX+ for 50 bucks need some opinion - Overclock.net - Overclocking.net says:
