GeForce 8800 GTS (G80) 320MB vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X should theoretically perform a small bit faster than the GeForce 8800 GTS (G80) 320MB in general. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 8800 GTS (G80) 320MB		63360 MB/sec
	Difference: 8640 (14%)

Texel Rate

The Radeon R9 M365X should be much (more or less 50%) more effective at AF than the GeForce 8800 GTS (G80) 320MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 12376 (50%)

Pixel Rate

The Radeon R9 M365X should be quite a bit (about 44%) better at anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 4540 (44%)

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 (measured in megabytes per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
