GeForce GTX 1630 vs GeForce GTX 650 Ti 2GB

Intro

Compare all of that to the GeForce GTX 650 Ti 2GB, which has GPU core speed of 928 MHz, and 2048 MB of GDDR5 memory running at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

	Difference: 3712 (7%)

Pixel Rate

The GeForce GTX 1630 should be much (about 88%) faster with regards to full screen anti-aliasing than the GeForce GTX 650 Ti 2GB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 12992 (88%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
