GeForce 8800 GTX vs Radeon R9 M365X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 8800 GTX should perform a little bit faster 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 (about 1%) more effective at anisotropic filtering 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 will be a little bit (more or less 7%) more effective at full screen anti-aliasing than the GeForce 8800 GTX, and also capable of handling higher screen resolutions without losing too much performance. (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: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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