Radeon R7 250X vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which has core speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs along with 112 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Performance-wise, the Radeon RX 6600 should in theory be a lot superior to the Radeon R7 250X in general. (explain)

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

Texel Rate

The Radeon RX 6600 should 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

If running with a high resolution is important to you, then the Radeon RX 6600 is a better choice, and very much so. (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: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
