GeForce GTX 1630 vs GeForce GTX 260

Intro

Compare that to the GeForce GTX 260, which comes with a core clock frequency of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and uses a 65 nm design. It is comprised of 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 13584 (14%)

Texel Rate

The GeForce GTX 1630 will be quite a bit (about 51%) more effective at texture filtering than the GeForce GTX 260. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTX 260		36864 Mtexels/sec
	Difference: 18816 (51%)

Pixel Rate

The GeForce GTX 1630 should be a lot (about 73%) faster with regards to AA than the GeForce GTX 260, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTX 260		16128 Mpixels/sec
	Difference: 11712 (73%)

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 (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
