GeForce 8800 Ultra vs Radeon R7 360

Intro

Compare all that to the Radeon R7 360, which comes with core clock speeds of 1050 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 48 Texture Address Units and 16 ROPs.

The Radeon R7 360 will be a lot (about 29%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 11232 (29%)

Pixel Rate

The Radeon R7 360 should be a bit (approximately 14%) more effective at anti-aliasing than the GeForce 8800 Ultra, and able to handle higher screen resolutions without losing too much performance. (explain)

Radeon R7 360		16800 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 2112 (14%)

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 (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
