GeForce GT 320 vs GeForce GTX 960

Intro

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

Compare all that to the GeForce GTX 960, which has GPU core speed of 1127 MHz, and 2048 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

GeForce GTX 960 112000 MB/sec
GeForce GT 320 25280 MB/sec
Difference: 86720 (343%)

Texel Rate

The GeForce GTX 960 is much (approximately 457%) more effective at AF than the GeForce GT 320. (explain)

GeForce GTX 960 72128 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 59168 (457%)

Pixel Rate

The GeForce GTX 960 should be quite a bit (more or less 735%) more effective at anti-aliasing than the GeForce GT 320, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 960 36064 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 31744 (735%)

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 largest amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
