GeForce 8800 GT 1GB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which features GPU core speed of 1015 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375X should be quite a bit faster than the GeForce 8800 GT 1GB overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M375X will be much (more or less 21%) more effective at AF than the GeForce 8800 GT 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X is a lot (approximately 69%) better at full screen anti-aliasing than the GeForce 8800 GT 1GB, and will be capable of handling higher screen resolutions better. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 6640 (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: Memory bandwidth is the maximum amount of information (measured 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 interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
