GeForce GTX 1630 vs GeForce GTX 550 Ti

Intro

Compare all that to the GeForce GTX 550 Ti, which comes with a core clock speed of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit memory bus, and uses a 40 nm design. It features 192 SPUs, 32 TAUs, and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 41 Watts (55%)

Memory Bandwidth

In theory, the GeForce GTX 550 Ti should be 0% faster than the GeForce GTX 1630 in general, because of its higher bandwidth. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 192 (0%)

Texel Rate

The GeForce GTX 1630 is a lot (approximately 93%) better at AF than the GeForce GTX 550 Ti. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 26880 (93%)

Pixel Rate

The GeForce GTX 1630 will be much (approximately 29%) more effective at full screen anti-aliasing than the GeForce GTX 550 Ti, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 6240 (29%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling 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 video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
