GeForce 9800 GTX vs Radeon R9 M365X

Intro

Compare those specs to the Radeon R9 M365X, which features clock speeds of 925 MHz on the GPU, and 1125 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R9 M365X 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 is a little bit (approximately 17%) more effective at AF than the Radeon R9 M365X. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 6200 (17%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 M365X is the winner, by far. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 9800 GTX		10800 Mpixels/sec
	Difference: 4000 (37%)

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 data (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling 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 that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
