GeForce GTX 280 vs Radeon R9 M375

Intro

Compare those specs to the Radeon R9 M375, which has GPU clock speed of 1015 MHz, and 4096 MB of DDR3 RAM running at 1100 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 280, in theory, should perform quite a bit faster than the Radeon R9 M375 in general. (explain)

GeForce GTX 280		141696 MB/sec
Radeon R9 M375		35200 MB/sec
	Difference: 106496 (303%)

Texel Rate

The GeForce GTX 280 should be a small bit (more or less 19%) faster with regards to texture filtering than the Radeon R9 M375. (explain)

GeForce GTX 280		48160 Mtexels/sec
Radeon R9 M375		40600 Mtexels/sec
	Difference: 7560 (19%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 280 is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 280		19264 Mpixels/sec
Radeon R9 M375		16240 Mpixels/sec
	Difference: 3024 (19%)

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 data (counted in megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of 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 applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
