Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M365X will be 25% faster than the GeForce 9600 GT 512MB overall, because of its greater data rate. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X is a lot (about 78%) more effective at AF than the GeForce 9600 GT 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 16200 (78%)

Pixel Rate

The Radeon R9 M365X should be much (about 42%) faster with regards to FSAA than the GeForce 9600 GT 512MB, and able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 4400 (42%)

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 information (in units of MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
