Radeon R9 295X2 vs Radeon RX 6650 XT

Intro

Compare those specifications to the Radeon RX 6650 XT, which makes use of a 7 nm design. AMD has set the core speed at 2055 MHz. The GDDR6 RAM is set to run at a frequency of 2190 MHz on this specific card. It features 2048 SPUs as well as 128 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
Radeon R9 295X2		500 Watts
	Difference: 324 Watts (184%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 295X2 should be quite a bit faster than the Radeon RX 6650 XT overall. (explain)

Radeon R9 295X2		640000 MB/sec
Radeon RX 6650 XT		287072 MB/sec
	Difference: 352928 (123%)

Texel Rate

The Radeon R9 295X2 should be quite a bit (about 36%) more effective at AF than the Radeon RX 6650 XT. (explain)

Radeon R9 295X2		358336 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 95296 (36%)

Pixel Rate

The Radeon RX 6650 XT should be a small bit (about 1%) better at AA than the Radeon R9 295X2, and will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
Radeon R9 295X2		130304 Mpixels/sec
	Difference: 1216 (1%)

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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the 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 the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
