GeForce GT 315 vs Radeon R9 M375X

Intro

Compare all that to the Radeon R9 M375X, which has a clock speed of 1015 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375X should in theory be a lot better 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 is quite a bit (about 306%) more effective at anisotropic filtering than the GeForce GT 315. (explain)

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

Pixel Rate

If using a high resolution 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: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
