GeForce GT 315 vs GeForce GTX 460 (OEM)

Intro

Compare those specs to the GeForce GTX 460 (OEM), which makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this specific card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 315		52 Watts
GeForce GTX 460 (OEM)		150 Watts
	Difference: 98 Watts (188%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 (OEM) should be 330% faster than the GeForce GT 315 in general, because of its higher data rate. (explain)

GeForce GTX 460 (OEM)		108800 MB/sec
GeForce GT 315		25280 MB/sec
	Difference: 83520 (330%)

Texel Rate

The GeForce GTX 460 (OEM) will be quite a bit (approximately 264%) better at texture filtering than the GeForce GT 315. (explain)

GeForce GTX 460 (OEM)		36400 Mtexels/sec
GeForce GT 315		10000 Mtexels/sec
	Difference: 26400 (264%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 (OEM) is a better choice, and very much so. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce GT 315		5000 Mpixels/sec
	Difference: 15800 (316%)

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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high 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 by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
