Radeon RX 6600 XT vs Radeon RX 6650 XT

Intro

The Radeon RX 6600 XT uses a 7 nm design. AMD has clocked the core frequency at 1968 MHz. The GDDR6 memory is set to run at a speed of 2000 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Compare those specs to the Radeon RX 6650 XT, which uses a 7 nm design. AMD has set the core frequency at 2055 MHz. The GDDR6 RAM works at a speed of 2190 MHz on this particular model. It features 2048 SPUs as well as 128 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600 XT 160 Watts
Radeon RX 6650 XT 176 Watts
Difference: 16 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6650 XT should be 10% faster than the Radeon RX 6600 XT overall, because of its greater data rate. (explain)

Radeon RX 6650 XT 287072 MB/sec
Radeon RX 6600 XT 262144 MB/sec
Difference: 24928 (10%)

Texel Rate

The Radeon RX 6650 XT is a little bit (about 4%) faster with regards to AF than the Radeon RX 6600 XT. (explain)

Radeon RX 6650 XT 263040 Mtexels/sec
Radeon RX 6600 XT 251904 Mtexels/sec
Difference: 11136 (4%)

Pixel Rate

The Radeon RX 6650 XT will be just a bit (about 4%) better at full screen anti-aliasing than the Radeon RX 6600 XT, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT 131520 Mpixels/sec
Radeon RX 6600 XT 125952 Mpixels/sec
Difference: 5568 (4%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
