GeForce GT 315 vs GeForce GTX Titan Black

Intro

Compare that to the GeForce GTX Titan Black, which comes with a core clock frequency of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It is made up of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
GeForce GTX Titan Black		250 Watts
	Difference: 198 Watts (381%)

Memory Bandwidth

The GeForce GTX Titan Black, in theory, should perform quite a bit faster than the GeForce GT 315 overall. (explain)

GeForce GTX Titan Black		336000 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 310720 (1229%)

Texel Rate

The GeForce GTX Titan Black is much (about 2034%) more effective at anisotropic filtering than the GeForce GT 315. (explain)

GeForce GTX Titan Black		213360 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 203360 (2034%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX Titan Black is superior to the GeForce GT 315, and very much so. (explain)

GeForce GTX Titan Black		42672 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 37672 (753%)

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 information (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high 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 amount of texture units by the core speed of the chip. The higher the texel rate, 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 could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
