GeForce 9800 GTX+ vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which comes with core clock speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M375X is 2% faster than the GeForce 9800 GTX+ in general, because of its higher bandwidth. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ should be a bit (about 16%) more effective at texture filtering than the Radeon R9 M375X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 6632 (16%)

Pixel Rate

The Radeon R9 M375X should be much (approximately 38%) more effective at FSAA than the GeForce 9800 GTX+, and also will be capable of handling higher resolutions more effectively. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 4432 (38%)

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 moved across the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
