GeForce GT 310 vs GeForce GTX 470

Intro

The GeForce GT 310 features a GPU clock speed of 589 MHz, and the 512 MB of DDR2 RAM is set to run at 1000 MHz through a 64-bit bus. It also is made up of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Compare those specifications to the GeForce GTX 470, which uses a 40 nm design. nVidia has set the core speed at 607 MHz. The GDDR5 memory works at a speed of 837 MHz on this specific model. It features 448 SPUs as well as 56 TAUs and 40 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 310 31 Watts
GeForce GTX 470 215 Watts
Difference: 184 Watts (594%)

Memory Bandwidth

In theory, the GeForce GTX 470 should be 737% faster than the GeForce GT 310 in general, due to its greater data rate. (explain)

GeForce GTX 470 133920 MB/sec
GeForce GT 310 16000 MB/sec
Difference: 117920 (737%)

Texel Rate

The GeForce GTX 470 will be much (more or less 621%) more effective at texture filtering than the GeForce GT 310. (explain)

GeForce GTX 470 33992 Mtexels/sec
GeForce GT 310 4712 Mtexels/sec
Difference: 29280 (621%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 470 is the winner, by a large margin. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GT 310 2356 Mpixels/sec
Difference: 21924 (931%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
