GeForce GTX 650 Ti vs Radeon R9 M375

Intro

Compare all that to the Radeon R9 M375, which comes with clock speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti should theoretically be much faster than the Radeon R9 M375 in general. (explain)

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

Texel Rate

The GeForce GTX 650 Ti is quite a bit (approximately 46%) better at anisotropic filtering 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 should be just a bit (about 9%) better at anti-aliasing than the GeForce GTX 650 Ti, and should be able to handle higher resolutions better. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card 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 amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
