GeForce GT 1030 vs GeForce GTX 275

Intro

Compare all that to the GeForce GTX 275, which comes with GPU clock speed of 633 MHz, and 896 MB of GDDR3 memory set to run at 1134 MHz through a 448-bit bus. It also is comprised of 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

GeForce GT 1030		49152 MB/sec
	Difference: 77856 (158%)

Texel Rate

The GeForce GTX 275 will be quite a bit (more or less 25%) more effective at texture filtering than the GeForce GT 1030. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 10160 (25%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GT 1030 is the winner, though not by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 2516 (14%)

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 information (measured in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed 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. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
