GeForce 9800 GX2 vs Radeon R9 M375X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9800 GX2 should theoretically be a lot superior to the Radeon R9 M375X in general. (explain)

GeForce 9800 GX2		128000 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 56000 (78%)

Texel Rate

The GeForce 9800 GX2 should be a lot (about 89%) better at AF than the Radeon R9 M375X. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 36200 (89%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GX2 is a better choice, not by a very large margin though. (explain)

GeForce 9800 GX2		19200 Mpixels/sec
Radeon R9 M375X		16240 Mpixels/sec
	Difference: 2960 (18%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
