Radeon R7 260X vs Radeon RX 6500 XT

Intro

Compare that to the Radeon RX 6500 XT, which has a GPU core clock speed of 2200 MHz, and 4096 MB of GDDR6 memory set to run at 2250 MHz through a 64-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
Radeon R7 260X		115 Watts
	Difference: 8 Watts (7%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT is 42% quicker than the Radeon R7 260X in general, because of its higher data rate. (explain)

Radeon RX 6500 XT		147456 MB/sec
Radeon R7 260X		104000 MB/sec
	Difference: 43456 (42%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (more or less 129%) more effective at anisotropic filtering than the Radeon R7 260X. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R7 260X		61600 Mtexels/sec
	Difference: 79200 (129%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6500 XT is a better choice, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R7 260X		17600 Mpixels/sec
	Difference: 52800 (300%)

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 largest amount of data (counted in megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, 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 number is worked out by multiplying the total texture units by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
