GeForce GT 310 vs Radeon R5 M230

Intro

The GeForce GT 310 makes use of a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR2 RAM runs at a frequency of 1000 MHz on this model. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

Compare that to the Radeon R5 M230, which has GPU core speed of 780 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also features 320 SPUs, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should have the same performance. (explain)

Texel Rate

The Radeon R5 M230 will be a lot (more or less 231%) faster with regards to anisotropic 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 running with high levels of AA is important to you, then the Radeon R5 M230 is a better choice, by far. (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: Bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
