GeForce GT 310 vs Radeon R5 M230

Intro

The GeForce GT 310 features clock speeds of 589 MHz on the GPU, and 1000 MHz on the 512 MB of DDR2 memory. It features 16 SPUs along with 8 TAUs and 4 ROPs.

Compare all of that to the Radeon R5 M230, which makes use of a 28 nm design. AMD has clocked the core speed at 780 MHz. The DDR3 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 320 SPUs along with 20 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The Radeon R5 M230 will be a lot (more or less 231%) more effective at texture filtering than the GeForce GT 310. (explain)

Radeon R5 M230 15600 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 10888 (231%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R5 M230 is the winner, and very much so. (explain)

Radeon R5 M230 3120 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 764 (32%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
