GeForce 8300 GS (OEM) vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which has clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 RAM. It features 512 SPUs along with 32 TAUs and 16 ROPs.

GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 65600 (1025%)

Texel Rate

The Radeon HD 7750 will be a lot (approximately 1322%) more effective at anisotropic filtering than the GeForce 8300 GS (OEM). (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 23800 (1322%)

Pixel Rate

If using a high resolution is important to you, then the Radeon HD 7750 is the winner, by far. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 11900 (1322%)

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 maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one 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 speed of the card. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
