GeForce GTX 650 Ti 2GB vs Radeon R9 M375X

Intro

Compare all of that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The GDDR5 RAM runs at a speed of 1125 MHz on this particular card. 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 should theoretically be just a bit faster than the Radeon R9 M375X in general. (explain)

GeForce GTX 650 Ti 2GB		86400 MB/sec
Radeon R9 M375X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 650 Ti 2GB is a lot (about 46%) faster with regards to texture filtering than the Radeon R9 M375X. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon R9 M375X		40600 Mtexels/sec
	Difference: 18792 (46%)

Pixel Rate

The Radeon R9 M375X is a small bit (more or less 9%) faster with regards to anti-aliasing than the GeForce GTX 650 Ti 2GB, and also should be capable of handling higher screen resolutions better. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1392 (9%)

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 (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
