GeForce 9500 GT DDR2 vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which uses a 28 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this specific card. It features 512 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

GeForce 9500 GT DDR2		16000 MB/sec
	Difference: 56000 (350%)

Texel Rate

The Radeon HD 7750 is much (approximately 191%) better at anisotropic filtering than the GeForce 9500 GT DDR2. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 16800 (191%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 7750 is a better choice, by a large margin. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9500 GT DDR2		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: Memory bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
