GeForce GT 1030 vs GeForce GT 320

Intro

Compare all of that to the GeForce GT 320, which features clock speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 memory. It features 72 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GT 320		43 Watts
	Difference: 13 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 1030 should be 94% quicker than the GeForce GT 320 overall, because of its greater data rate. (explain)

GeForce GT 1030		49152 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 23872 (94%)

Texel Rate

The GeForce GT 1030 should be much (approximately 212%) better at anisotropic 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 should be a lot (about 369%) faster with regards to full screen anti-aliasing than the GeForce GT 320, and also able to handle higher resolutions without losing too much performance. (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
