GeForce 8800 GT 1GB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which has clock speeds of 800 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R9 M370X should theoretically be a lot superior to the GeForce 8800 GT 1GB overall. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 8800 GT 1GB should be just a bit (more or less 5%) more effective at texture filtering than the Radeon R9 M370X. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

The Radeon R9 M370X will be a lot (about 33%) more effective at anti-aliasing than the GeForce 8800 GT 1GB, and will be able to handle higher resolutions better. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 3200 (33%)

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 (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
