GeForce GTS 450 vs GeForce GTX 1630

Intro

Compare all that to the GeForce GTX 1630, which comes with GPU clock speed of 1740 MHz, and 4096 MB of GDDR6 RAM set to run at 1500 MHz through a 64-bit bus. It also is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTS 450		106 Watts
	Difference: 31 Watts (41%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1630 will be 70% faster than the GeForce GTS 450 overall, due to its higher data rate. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTS 450		57728 MB/sec
	Difference: 40576 (70%)

Texel Rate

The GeForce GTX 1630 will be a lot (about 122%) better at texture filtering than the GeForce GTS 450. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 30624 (122%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 1630 is superior to the GeForce GTS 450, and very much so. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTS 450		12528 Mpixels/sec
	Difference: 15312 (122%)

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 data (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
