GeForce GT 320 vs GeForce GTX Titan X

Intro

Compare those specifications to the GeForce GTX Titan X, which comes with a clock speed of 1000 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 384-bit memory bus, and uses a 28 nm design. It features 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX Titan X		250 Watts
	Difference: 207 Watts (481%)

Memory Bandwidth

The GeForce GTX Titan X should in theory be a lot faster than the GeForce GT 320 overall. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 310720 (1229%)

Texel Rate

The GeForce GTX Titan X will be quite a bit (more or less 1381%) more effective at AF than the GeForce GT 320. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 179040 (1381%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan X is a better choice, and very much so. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 91680 (2122%)

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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
