GeForce GT 315 vs Radeon R9 M375X

Intro

Compare that to the Radeon R9 M375X, which uses a 28 nm design. AMD has clocked the core frequency at 1015 MHz. The GDDR5 memory works at a speed of 1125 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M375X, in theory, should perform quite a bit 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 much (approximately 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

The Radeon R9 M375X is quite a bit (about 225%) faster with regards to FSAA than the GeForce GT 315, and will be capable of handling higher screen resolutions without losing too much performance. (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 data (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
