GeForce GT 315 vs Radeon R5 M230

Intro

Compare all that to the Radeon R5 M230, which features GPU clock speed of 780 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GT 315 should be 58% quicker than the Radeon R5 M230 in general, due to its greater data rate. (explain)

GeForce GT 315		25280 MB/sec
Radeon R5 M230		16000 MB/sec
	Difference: 9280 (58%)

Texel Rate

The Radeon R5 M230 should be quite a bit (about 56%) faster with regards to anisotropic filtering than the GeForce GT 315. (explain)

Radeon R5 M230		15600 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 5600 (56%)

Pixel Rate

The GeForce GT 315 will be a lot (more or less 60%) faster with regards to FSAA than the Radeon R5 M230, and should be able to handle higher resolutions better. (explain)

GeForce GT 315		5000 Mpixels/sec
Radeon R5 M230		3120 Mpixels/sec
	Difference: 1880 (60%)

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 transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
