GeForce GT 1030 vs GeForce GT 320

Intro

The GeForce GT 1030 comes with clock speeds of 1265 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 memory. It features 384 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

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

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to 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 potential to reach the max fill rate.
