GeForce GTX 460 1GB vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core frequency at 1015 MHz. The DDR3 memory runs at a frequency of 1100 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 460 1GB should in theory be quite a bit better than the Radeon R9 M375 in general. (explain)

GeForce GTX 460 1GB		115200 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 80000 (227%)

Texel Rate

The Radeon R9 M375 should be just a bit (more or less 7%) better at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 2800 (7%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 1GB is superior to the Radeon R9 M375, and very much so. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 5360 (33%)

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 max amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the 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 amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
