GeForce GT 310 vs Geforce GTX 770

Intro

Compare all that to the Geforce GTX 770, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1046 MHz. The GDDR5 RAM runs at a frequency of 1753 MHz on this model. It features 1536 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310		31 Watts
Geforce GTX 770		230 Watts
	Difference: 199 Watts (642%)

Memory Bandwidth

In theory, the Geforce GTX 770 is 1302% faster than the GeForce GT 310 in general, due to its higher bandwidth. (explain)

Geforce GTX 770		224384 MB/sec
GeForce GT 310		16000 MB/sec
	Difference: 208384 (1302%)

Texel Rate

The Geforce GTX 770 should be quite a bit (approximately 2741%) more effective at AF than the GeForce GT 310. (explain)

Geforce GTX 770		133888 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 129176 (2741%)

Pixel Rate

The Geforce GTX 770 is a lot (approximately 1321%) better at FSAA than the GeForce GT 310, and also should be capable of handling higher resolutions while still performing well. (explain)

Geforce GTX 770		33472 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 31116 (1321%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
