Radeon R7 M265 vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which features a clock frequency of 1825 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 256-bit bus, and makes use of a 7 nm design. It is comprised of 5120 SPUs, 320 TAUs, and 128 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 6900 XT should in theory perform much faster than the Radeon R7 M265 overall. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 492288 (1538%)

Texel Rate

The Radeon RX 6900 XT will be quite a bit (approximately 3256%) better at texture filtering than the Radeon R7 M265. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 566600 (3256%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6900 XT is superior to the Radeon R7 M265, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 227800 (3928%)

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 (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
