GeForce GTX 1630 vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which has a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 RAM set to run at 999 MHz through a 448-bit bus. It also is comprised of 240 SPUs, 80 TAUs, and 28 Raster Operation Units.

GeForce GTX 1630		98304 MB/sec
	Difference: 125472 (128%)

Texel Rate

The GeForce GTX 295 is a lot (approximately 66%) faster with regards to AF than the GeForce GTX 1630. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 36480 (66%)

Pixel Rate

The GeForce GTX 295 is just a bit (about 16%) faster with regards to AA than the GeForce GTX 1630, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 4416 (16%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the 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 processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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