GeForce 8800 GTS (G92) vs Radeon R9 M385X

Intro

Compare all of that to the Radeon R9 M385X, which comes with a GPU core clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M385X should in theory perform a lot faster than the GeForce 8800 GTS (G92) in general. (explain)

Radeon R9 M385X		96000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 33920 (55%)

Texel Rate

The Radeon R9 M385X is much (more or less 48%) better at texture filtering than the GeForce 8800 GTS (G92). (explain)

Radeon R9 M385X		61600 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 20000 (48%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M385X is the winner, and very much so. (explain)

Radeon R9 M385X		17600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 7200 (69%)

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 data (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
