GeForce GTX 650 Ti 2GB vs Radeon R9 M365X

Intro

Compare all that to the Radeon R9 M365X, which makes use of 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 model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti 2GB, in theory, should perform a small bit faster than the Radeon R9 M365X in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB will be much (about 61%) more effective at texture filtering than the Radeon R9 M365X. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M365X		37000 Mtexels/sec
	Difference: 22392 (61%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti 2GB is superior to the Radeon R9 M365X, not by a very large margin though. (explain)

GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 48 (0%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 can be processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better 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 number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
