GeForce 9800 GX2 vs GeForce GTX 1630

Intro

Compare that to the GeForce GTX 1630, which has GPU clock speed of 1740 MHz, and 4096 MB of GDDR6 RAM running at 1500 MHz through a 64-bit bus. It also is made up of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Texel Rate

The GeForce 9800 GX2 is quite a bit (approximately 38%) more effective at AF than the GeForce GTX 1630. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 21120 (38%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 1630 is the winner, and very much so. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 8640 (45%)

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 data (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range 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 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill 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.
