Radeon R7 250X vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has GPU core speed of 1626 MHz, and 8192 MB of GDDR6 memory running at 1750 MHz through a 128-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 64 Raster Operation Units.

Radeon R7 250X		95 Watts
Radeon RX 6600		132 Watts
	Difference: 37 Watts (39%)

Memory Bandwidth

As far as performance goes, the Radeon RX 6600 should in theory be much superior to the Radeon R7 250X overall. (explain)

Radeon RX 6600		229376 MB/sec
Radeon R7 250X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 6600 will be quite a bit (about 355%) more effective at AF than the Radeon R7 250X. (explain)

Radeon RX 6600		182112 Mtexels/sec
Radeon R7 250X		40000 Mtexels/sec
	Difference: 142112 (355%)

Pixel Rate

The Radeon RX 6600 should be a lot (more or less 550%) faster with regards to FSAA than the Radeon R7 250X, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 6600		104064 Mpixels/sec
Radeon R7 250X		16000 Mpixels/sec
	Difference: 88064 (550%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
