GeForce GT 315 vs Radeon R9 M375X

Intro

Compare those specifications to the Radeon R9 M375X, which comes with a GPU core clock speed of 1015 MHz, and 4096 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X should theoretically perform a lot faster than the GeForce GT 315 overall. (explain)

Radeon R9 M375X		72000 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 46720 (185%)

Texel Rate

The Radeon R9 M375X will be quite a bit (approximately 306%) more effective at AF than the GeForce GT 315. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 30600 (306%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M375X is superior to the GeForce GT 315, by far. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 11240 (225%)

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 largest amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
