GeForce GTX 965M vs Radeon R9 M365X

Intro

Compare all of that to the Radeon R9 M365X, which uses a 28 nm design. AMD has clocked the core speed at 925 MHz. The GDDR5 memory is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M365X should theoretically be just a bit superior to the GeForce GTX 965M overall. (explain)

Radeon R9 M365X		72000 MB/sec
GeForce GTX 965M		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The GeForce GTX 965M should be quite a bit (about 63%) better at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 965M		60416 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 23416 (63%)

Pixel Rate

The GeForce GTX 965M will be a lot (more or less 104%) more effective at full screen anti-aliasing than the Radeon R9 M365X, and capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 965M		30208 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 15408 (104%)

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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
