GeForce GT 1030 vs GeForce GTX 275

Intro

Compare all of that to the GeForce GTX 275, which uses a 55 nm design. nVidia has set the core frequency at 633 MHz. The GDDR3 RAM is set to run at a frequency of 1134 MHz on this specific model. It features 240 SPUs along with 80 TAUs and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GTX 275		219 Watts
	Difference: 189 Watts (630%)

Memory Bandwidth

The GeForce GTX 275, in theory, should perform a lot faster than the GeForce GT 1030 in general. (explain)

GeForce GTX 275		127008 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 77856 (158%)

Texel Rate

The GeForce GTX 275 will be quite a bit (more or less 25%) faster with regards to AF than the GeForce GT 1030. (explain)

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

Pixel Rate

The GeForce GT 1030 is a little bit (about 14%) better at anti-aliasing than the GeForce GTX 275, and also should be able to handle higher screen resolutions without slowing down too much. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
