GeForce 8800 GTS (G92) vs Radeon R9 M270X

Intro

Compare all that to the Radeon R9 M270X, which has a GPU core clock speed of 725 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M270X should perform just a bit faster than the GeForce 8800 GTS (G92) overall. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 9920 (16%)

Texel Rate

The GeForce 8800 GTS (G92) should be much (more or less 43%) faster with regards to anisotropic filtering than the Radeon R9 M270X. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon R9 M270X		29000 Mtexels/sec
	Difference: 12600 (43%)

Pixel Rate

The Radeon R9 M270X should be a bit (approximately 12%) better at anti-aliasing than the GeForce 8800 GTS (G92), and capable of handling higher screen resolutions while still performing well. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 1200 (12%)

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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are applied per second. This is calculated by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
