Radeon RX 460 vs Radeon RX 5700 XT 50th Anniversary Edition

Intro

Compare those specifications to the Radeon RX 5700 XT 50th Anniversary Edition, which makes use of a 7 nm design. AMD has clocked the core speed at 1680 MHz. The GDDR6 memory runs at a frequency of 1750 MHz on this specific card. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Radeon RX 5700 XT 50th Anniversary Edition		235 Watts
	Difference: 160 Watts (213%)

Memory Bandwidth

The Radeon RX 5700 XT 50th Anniversary Edition, in theory, should perform much faster than the Radeon RX 460 in general. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		458752 MB/sec
Radeon RX 460		112000 MB/sec
	Difference: 346752 (310%)

Texel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (more or less 340%) faster with regards to AF than the Radeon RX 460. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		268800 Mtexels/sec
Radeon RX 460		61040 Mtexels/sec
	Difference: 207760 (340%)

Pixel Rate

The Radeon RX 5700 XT 50th Anniversary Edition should be quite a bit (about 517%) more effective at full screen anti-aliasing than the Radeon RX 460, and also able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 5700 XT 50th Anniversary Edition		107520 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 90080 (517%)

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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must 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 AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many 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.
