GeForce 9800 GX2 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which comes with core speeds of 1015 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9800 GX2, in theory, should perform quite a bit faster than 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 will be quite a bit (about 89%) faster with regards to anisotropic filtering than the Radeon R9 M375X. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is a better choice, but only just. (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 data (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
