GeForce 9800 GX2 vs Radeon R9 M370X

Intro

Compare all that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory is set to run at a frequency of 1125 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9800 GX2 should be 78% faster than the Radeon R9 M370X in general, because of its greater data rate. (explain)

GeForce 9800 GX2		128000 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 56000 (78%)

Texel Rate

The GeForce 9800 GX2 should be a lot (more or less 140%) better at anisotropic filtering than the Radeon R9 M370X. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
Radeon R9 M370X		32000 Mtexels/sec
	Difference: 44800 (140%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9800 GX2 is a better choice, by far. (explain)

GeForce 9800 GX2		19200 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 6400 (50%)

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 megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
