GeForce 8300 GS (OEM) vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which features core speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 720 SPUs as well as 36 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8300 GS (OEM)		40 Watts
Radeon HD 6750 1GB		86 Watts
	Difference: 46 Watts (115%)

Memory Bandwidth

In theory, the Radeon HD 6750 1GB will be 900% quicker than the GeForce 8300 GS (OEM) in general, because of its higher data rate. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 57600 (900%)

Texel Rate

The Radeon HD 6750 1GB will be much (approximately 1350%) more effective at AF than the GeForce 8300 GS (OEM). (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 24300 (1350%)

Pixel Rate

The Radeon HD 6750 1GB is quite a bit (approximately 1189%) more effective at FSAA than the GeForce 8300 GS (OEM), and also should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 6750 1GB		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: Bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
