GeForce 8800 GTX vs Radeon R7 360

Intro

Compare all of that to the Radeon R7 360, which features a GPU core clock speed of 1050 MHz, and 2048 MB of GDDR5 memory set to run at 1625 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 16 ROPs.

GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 13600 (37%)

Pixel Rate

The Radeon R7 360 will be a lot (approximately 22%) more effective at anti-aliasing than the GeForce 8800 GTX, and capable of handling higher screen resolutions more effectively. (explain)

Radeon R7 360		16800 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 3000 (22%)

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 (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, the result 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount 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 per second.

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