Radeon R7 250X 2GB vs Radeon RX 6600 XT

Intro

Compare that to the Radeon RX 6600 XT, which uses a 7 nm design. AMD has set the core speed at 1968 MHz. The GDDR6 RAM works at a speed of 2000 MHz on this model. It features 2048 SPUs as well as 128 TAUs and 64 ROPs.

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is superior to the Radeon R7 250X 2GB, by a large margin. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
Radeon R7 250X 2GB		16000 Mpixels/sec
	Difference: 109952 (687%)

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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
