GeForce GT 315 vs Radeon R9 295X2

Intro

Compare all of that to the Radeon R9 295X2, which makes use of a 28 nm design. AMD has clocked the core speed at 1018 MHz. The GDDR5 RAM works at a frequency of 1250 MHz on this specific model. It features 2816 SPUs along with 176 Texture Address Units and 64 ROPs.

GeForce GT 315		10000 Mtexels/sec
	Difference: 348336 (3483%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 295X2 is superior to the GeForce GT 315, by far. (explain)

Radeon R9 295X2		130304 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 125304 (2506%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
