GeForce 8800 GT 256MB vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X should be 61% quicker than the GeForce 8800 GT 256MB in general, due to its higher bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
GeForce 8800 GT 256MB		44800 MB/sec
	Difference: 27200 (61%)

Texel Rate

The GeForce 8800 GT 256MB is a little bit (about 5%) more effective at AF than the Radeon R9 M370X. (explain)

GeForce 8800 GT 256MB		33600 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 1600 (5%)

Pixel Rate

The Radeon R9 M370X should be a lot (more or less 33%) better at FSAA than the GeForce 8800 GT 256MB, and also will be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M370X		12800 Mpixels/sec
GeForce 8800 GT 256MB		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 information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
