GeForce 8800 GTX vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which features a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTX is 20% quicker than the Radeon R9 M370X in general, due to its greater bandwidth. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce 8800 GTX will be a bit (about 15%) faster with regards to texture filtering than the Radeon R9 M370X. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 4800 (15%)

Pixel Rate

The GeForce 8800 GTX will be a small bit (about 8%) more effective at anti-aliasing than the Radeon R9 M370X, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 1000 (8%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
