GeForce GT 1030 vs GeForce GT 320

Intro

The GeForce GT 1030 makes use of a 16 nm design. nVidia has clocked the core speed at 1265 MHz. The GDDR5 memory runs at a speed of 1502 MHz on this particular card. It features 384 SPUs as well as 32 TAUs and 16 ROPs.

Compare all of that to the GeForce GT 320, which comes with a GPU core clock speed of 540 MHz, and 1024 MB of GDDR3 RAM set to run at 790 MHz through a 128-bit bus. It also features 72 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

GeForce GT 1030 40480 Mtexels/sec
GeForce GT 320 12960 Mtexels/sec
Difference: 27520 (212%)

Pixel Rate

The GeForce GT 1030 is much (approximately 369%) more effective at FSAA than the GeForce GT 320, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 1030 20240 Mpixels/sec
GeForce GT 320 4320 Mpixels/sec
Difference: 15920 (369%)

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 (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
