Radeon R9 M265X vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core frequency at 1670 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this particular model. It features 1408 SPUs along with 88 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon RX 5500 should theoretically be much faster than the Radeon R9 M265X in general. (explain)

Radeon RX 5500		229376 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 157376 (219%)

Texel Rate

The Radeon RX 5500 will be a lot (about 539%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon RX 5500		146960 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 123960 (539%)

Pixel Rate

The Radeon RX 5500 should be much (more or less 481%) faster with regards to full screen anti-aliasing than the Radeon R9 M265X, and should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 44240 (481%)

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 maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
