GeForce 9800 GX2 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 memory works at a frequency of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 175104 (228%)

Pixel Rate

The Radeon RX 6600 XT is much (about 556%) better at anti-aliasing than the GeForce 9800 GX2, and also able to handle higher resolutions while still performing well. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 106752 (556%)

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 maximum amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
