GeForce 8300 GS (OEM) vs Radeon HD 6750

Intro

Compare that to the Radeon HD 6750, which comes with a GPU core clock speed of 725 MHz, and 512 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 720 Stream Processors, 36 TAUs, and 16 Raster Operation Units.

Radeon HD 6750		26100 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 24300 (1350%)

Pixel Rate

The Radeon HD 6750 will be quite a bit (approximately 1189%) more effective at FSAA than the GeForce 8300 GS (OEM), and able to handle higher resolutions without losing too much performance. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 10700 (1189%)

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 data (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
