Radeon HD 3850 X2 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which makes use of a 7 nm design. AMD has set the core frequency at 1626 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this particular model. It features 1792 SPUs along with 112 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 6600 should in theory be a lot faster than the Radeon HD 3850 X2 in general. (explain)

Radeon RX 6600		229376 MB/sec
Radeon HD 3850 X2		105984 MB/sec
	Difference: 123392 (116%)

Texel Rate

The Radeon RX 6600 will be quite a bit (more or less 752%) faster with regards to AF than the Radeon HD 3850 X2. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon HD 3850 X2		21376 Mtexels/sec
	Difference: 160736 (752%)

Pixel Rate

The Radeon RX 6600 is much (about 387%) better at FSAA than the Radeon HD 3850 X2, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon HD 3850 X2		21376 Mpixels/sec
	Difference: 82688 (387%)

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 transferred past the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
