GeForce GT 1030 vs GeForce GTS 450

Intro

Compare those specs to the GeForce GTS 450, which comes with a GPU core clock speed of 783 MHz, and 512 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

GeForce GT 1030		30 Watts
GeForce GTS 450		106 Watts
	Difference: 76 Watts (253%)

Memory Bandwidth

Theoretically, the GeForce GTS 450 should perform just a bit faster than the GeForce GT 1030 in general. (explain)

GeForce GTS 450		57728 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 8576 (17%)

Texel Rate

The GeForce GT 1030 is much (more or less 62%) more effective at anisotropic filtering than the GeForce GTS 450. (explain)

GeForce GT 1030		40480 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 15424 (62%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 1030 is a better choice, by a large margin. (explain)

GeForce GT 1030		20240 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 7712 (62%)

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 largest amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
