GeForce GTX 275 vs Radeon R9 M370X

Intro

Compare all of that to the Radeon R9 M370X, which uses a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 memory runs at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Radeon R9 M370X		32000 Mtexels/sec
	Difference: 18640 (58%)

Pixel Rate

The GeForce GTX 275 should be a lot (about 38%) better at FSAA than the Radeon R9 M370X, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon R9 M370X		12800 Mpixels/sec
	Difference: 4924 (38%)

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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
