GeForce 8300 GS (OEM) vs Radeon HD 6850

Intro

Compare all of that to the Radeon HD 6850, which makes use of a 40 nm design. AMD has set the core speed at 775 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this specific card. It features 960 SPUs along with 48 Texture Address Units and 32 ROPs.

GeForce 8300 GS (OEM)		40 Watts
Radeon HD 6850		127 Watts
	Difference: 87 Watts (218%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6850 will be 1900% quicker than the GeForce 8300 GS (OEM) overall, because of its greater data rate. (explain)

Radeon HD 6850		128000 MB/sec
GeForce 8300 GS (OEM)		6400 MB/sec
	Difference: 121600 (1900%)

Texel Rate

The Radeon HD 6850 is a lot (about 1967%) more effective at texture filtering than the GeForce 8300 GS (OEM). (explain)

Radeon HD 6850		37200 Mtexels/sec
GeForce 8300 GS (OEM)		1800 Mtexels/sec
	Difference: 35400 (1967%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 6850 is superior to the GeForce 8300 GS (OEM), and very much so. (explain)

Radeon HD 6850		24800 Mpixels/sec
GeForce 8300 GS (OEM)		900 Mpixels/sec
	Difference: 23900 (2656%)

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 transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
