GeForce GT 310 vs Radeon R5 M230

Intro

Compare those specifications to the Radeon R5 M230, which features a GPU core clock speed of 780 MHz, and 2048 MB of DDR3 RAM set to run at 1000 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

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

Texel Rate

The Radeon R5 M230 should be quite a bit (approximately 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

The Radeon R5 M230 is a lot (about 32%) more effective at FSAA than the GeForce GT 310, and also will be capable of handling higher screen resolutions more effectively. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number 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 graphics 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
