GeForce GTX 460 (OEM) vs Radeon R9 M375

Intro

Compare all that to the Radeon R9 M375, which makes use of a 28 nm design. AMD has set the core speed at 1015 MHz. The DDR3 memory runs at a speed of 1100 MHz on this particular card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

GeForce GTX 460 (OEM)		108800 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 73600 (209%)

Texel Rate

The Radeon R9 M375 should be just a bit (approximately 12%) faster with regards to texture filtering than the GeForce GTX 460 (OEM). (explain)

Radeon R9 M375		40600 Mtexels/sec
GeForce GTX 460 (OEM)		36400 Mtexels/sec
	Difference: 4200 (12%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 460 (OEM) is the winner, by far. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 4560 (28%)

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 (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at 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 per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
