GeForce 8800 GTX vs Radeon R7 360

Intro

Compare all of that to the Radeon R7 360, which has a clock frequency of 1050 MHz and a GDDR5 memory speed of 1625 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 768 SPUs, 48 Texture Address Units, and 16 ROPs.

Radeon R7 360		100 Watts
GeForce 8800 GTX		155 Watts
	Difference: 55 Watts (55%)

Memory Bandwidth

In theory, the Radeon R7 360 should be 20% quicker than the GeForce 8800 GTX overall, due to its higher bandwidth. (explain)

Radeon R7 360		104000 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 17600 (20%)

Texel Rate

The Radeon R7 360 will be much (approximately 37%) more effective at texture filtering than the GeForce 8800 GTX. (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 13600 (37%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R7 360 is the winner, by far. (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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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