GeForce GT 1030 vs GeForce GT 320

Intro

The GeForce GT 1030 uses a 16 nm design. nVidia has clocked the core frequency at 1265 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this particular card. It features 384 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the GeForce GT 320, which has a GPU core clock speed of 540 MHz, and 1024 MB of GDDR3 memory running at 790 MHz through a 128-bit bus. It also features 72 SPUs, 24 Texture Address Units, and 8 ROPs.

GeForce GT 320 25280 MB/sec
Difference: 23872 (94%)

Texel Rate

The GeForce GT 1030 should be quite a bit (more or less 212%) better at texture filtering than the GeForce GT 320. (explain)

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

Pixel Rate

The GeForce GT 1030 is much (about 369%) faster with regards to AA than the GeForce GT 320, and also should be capable of handling higher screen resolutions without slowing down too much. (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 maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels 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 amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
