GeForce GTX 1630 vs GeForce GTX 260

Intro

Compare those specifications to the GeForce GTX 260, which makes use of a 65 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this particular card. It features 192 SPUs as well as 64 TAUs and 28 ROPs.

GeForce GTX 1630		75 Watts
GeForce GTX 260		182 Watts
	Difference: 107 Watts (143%)

Memory Bandwidth

In theory, the GeForce GTX 260 should perform a small bit faster than the GeForce GTX 1630 in general. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 13584 (14%)

Texel Rate

The GeForce GTX 1630 should 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 quite a bit (more or less 73%) faster with regards to AA than the GeForce GTX 260, and should be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 can be applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
