Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M370X should theoretically be quite a bit better than the GeForce 8800 GT 512MB in general. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 8800 GT 512MB should be a bit (about 5%) more effective at AF than the Radeon R9 M370X. (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

The Radeon R9 M370X is much (approximately 33%) faster with regards to anti-aliasing than the GeForce 8800 GT 512MB, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 8800 GT 512MB		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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
