GeForce 9800 GTX+ vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which features a core clock frequency of 925 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M365X, in theory, should be a bit faster than the GeForce 9800 GTX+ overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 9800 GTX+		70400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The GeForce 9800 GTX+ will be a lot (about 28%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 10232 (28%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M365X is superior to the GeForce 9800 GTX+, by a large margin. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 2992 (25%)

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 largest amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the bus 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 bandwidth is, 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 per second. This number is worked out by multiplying the total number of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 potential to get to the max fill rate.
