GeForce GT 310 vs Radeon R7 240

Intro

Compare those specs to the Radeon R7 240, which has GPU clock speed of 730 MHz, and 2048 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is comprised of 320 SPUs, 20 Texture Address Units, and 8 ROPs.

Radeon R7 240		30 Watts
GeForce GT 310		31 Watts
	Difference: 1 Watts (3%)

Memory Bandwidth

As far as performance goes, the Radeon R7 240 should in theory be quite a bit better than the GeForce GT 310 in general. (explain)

Radeon R7 240		28800 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 12800 (80%)

Texel Rate

The Radeon R7 240 should be much (approximately 210%) better at texture filtering than the GeForce GT 310. (explain)

Radeon R7 240		14600 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 9888 (210%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon R7 240 is superior to the GeForce GT 310, by far. (explain)

Radeon R7 240		5840 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 3484 (148%)

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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If it uses 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
