GeForce GTX 650 vs Radeon R9 M375

Intro

Compare those specifications to the Radeon R9 M375, which makes use of a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The DDR3 RAM is set to run at a speed of 1100 MHz on this card. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650, in theory, should be a lot faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 44800 (127%)

Texel Rate

The Radeon R9 M375 is a little bit (about 20%) faster with regards to anisotropic filtering than the GeForce GTX 650. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 650		33856 Mtexels/sec
	Difference: 6744 (20%)

Pixel Rate

The GeForce GTX 650 is a bit (about 4%) better at full screen anti-aliasing than the Radeon R9 M375, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 688 (4%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
