GeForce GTX 650 Ti vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which features GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti will be 20% faster than the Radeon R9 M365X in general, due to its higher data rate. (explain)

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

Texel Rate

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

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 650 Ti is a better choice, though only just barely. (explain)

GeForce GTX 650 Ti		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 data (counted in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount 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 better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
