GeForce 9500 GT 1GB GDDR3 vs Radeon HD 7750

Intro

Compare those specifications to the Radeon HD 7750, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this particular card. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

GeForce 9500 GT 1GB GDDR3		50 Watts
Radeon HD 7750		55 Watts
	Difference: 5 Watts (10%)

Memory Bandwidth

As far as performance goes, the Radeon HD 7750 should theoretically be a lot better than the GeForce 9500 GT 1GB GDDR3 overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9500 GT 1GB GDDR3		25600 MB/sec
	Difference: 46400 (181%)

Texel Rate

The Radeon HD 7750 should be quite a bit (about 191%) more effective at AF than the GeForce 9500 GT 1GB GDDR3. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 9500 GT 1GB 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 the winner, by a large margin. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9500 GT 1GB 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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
