GeForce GT 1030 vs GeForce GTS 450

Intro

Compare all of that to the GeForce GTS 450, which comes with a clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 16 Raster Operation Units.

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

Memory Bandwidth

The GeForce GTS 450, in theory, should be a little bit faster than the GeForce GT 1030 overall. (explain)

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

Texel Rate

The GeForce GT 1030 should be a lot (approximately 62%) more effective at AF 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 screen resolution is important to you, then the GeForce GT 1030 is superior to the GeForce GTS 450, and very much so. (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: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
