GeForce GTX 650 Ti vs Radeon R9 M375

Intro

Compare that to the Radeon R9 M375, which uses a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 RAM is set to run at a speed of 1100 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti should in theory perform much faster than the Radeon R9 M375 overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 51200 (145%)

Texel Rate

The GeForce GTX 650 Ti should be much (approximately 46%) faster with regards to AF than the Radeon R9 M375. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 18792 (46%)

Pixel Rate

The Radeon R9 M375 will be a small bit (more or less 9%) faster with regards to FSAA than the GeForce GTX 650 Ti, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon R9 M375		16240 Mpixels/sec
GeForce GTX 650 Ti		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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should 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 AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
