GeForce GT 320 vs Geforce GTX 760

Intro

The GeForce GT 320 has a clock speed of 540 MHz and a GDDR3 memory frequency of 790 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Geforce GTX 760, which features core clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320 43 Watts
Geforce GTX 760 170 Watts
Difference: 127 Watts (295%)

Memory Bandwidth

In theory, the Geforce GTX 760 should be 661% quicker than the GeForce GT 320 in general, because of its higher data rate. (explain)

Geforce GTX 760 192256 MB/sec
GeForce GT 320 25280 MB/sec
Difference: 166976 (661%)

Texel Rate

The Geforce GTX 760 should be a lot (about 626%) more effective at AF than the GeForce GT 320. (explain)

Geforce GTX 760 94080 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 81120 (626%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, by a large margin. (explain)

Geforce GTX 760 31360 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 27040 (626%)

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 data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
