GeForce GTX 650 Ti vs Radeon R9 M375

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 Ti should be 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 quite a bit (about 46%) better at 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 just a bit (approximately 9%) faster with regards to FSAA than the GeForce GTX 650 Ti, and should be capable of handling higher resolutions without losing too much performance. (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 information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
