GeForce 8800 GTX vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which features a clock speed of 925 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 8800 GTX should in theory be a little bit better than the Radeon R9 M365X in general. (explain)

GeForce 8800 GTX		86400 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The Radeon R9 M365X will be a small bit (more or less 1%) better at AF than the GeForce 8800 GTX. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 200 (1%)

Pixel Rate

The Radeon R9 M365X is just a bit (approximately 7%) better at FSAA than the GeForce 8800 GTX, and also should be able to handle higher screen resolutions better. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 1000 (7%)

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 MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
