GeForce 9500 GT 512MB GDDR3 vs Radeon HD 7750

Intro

The GeForce 9500 GT 512MB GDDR3 comes with a GPU core clock speed of 550 MHz, and the 512 MB of GDDR3 memory is set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 Texture Address Units, and 8 ROPs.

Compare those specs to the Radeon HD 7750, which features a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also features 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9500 GT 512MB GDDR3 50 Watts
Radeon HD 7750 55 Watts
Difference: 5 Watts (10%)

Memory Bandwidth

In theory, the Radeon HD 7750 will be 181% quicker than the GeForce 9500 GT 512MB GDDR3 overall, due to its higher bandwidth. (explain)

Radeon HD 7750 72000 MB/sec
GeForce 9500 GT 512MB GDDR3 25600 MB/sec
Difference: 46400 (181%)

Texel Rate

The Radeon HD 7750 is quite a bit (about 191%) better at AF than the GeForce 9500 GT 512MB GDDR3. (explain)

Radeon HD 7750 25600 Mtexels/sec
GeForce 9500 GT 512MB GDDR3 8800 Mtexels/sec
Difference: 16800 (191%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is a better choice, and very much so. (explain)

Radeon HD 7750 12800 Mpixels/sec
GeForce 9500 GT 512MB GDDR3 4400 Mpixels/sec
Difference: 8400 (191%)

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 max amount of information (measured in megabytes per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
