GeForce 8800 GT 256MB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X will be 61% faster than the GeForce 8800 GT 256MB overall, because of its higher data rate. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 8800 GT 256MB		44800 MB/sec
	Difference: 27200 (61%)

Texel Rate

The Radeon R9 M375X will be a lot (approximately 21%) more effective at AF than the GeForce 8800 GT 256MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 8800 GT 256MB		33600 Mtexels/sec
	Difference: 7000 (21%)

Pixel Rate

The Radeon R9 M375X will be quite a bit (about 69%) faster with regards to anti-aliasing than the GeForce 8800 GT 256MB, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 8800 GT 256MB		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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
