Radeon RX 460 vs Radeon RX 5700

Intro

The Radeon RX 460 makes use of a 14 nm design. AMD has set the core speed at 1090 MHz. The GDDR5 RAM is set to run at a speed of 1750 MHz on this model. It features 896 SPUs as well as 56 TAUs and 16 ROPs.

Compare those specifications to the Radeon RX 5700, which comes with GPU clock speed of 1465 MHz, and 8096 MB of GDDR6 RAM running at 14000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 TAUs, and 64 ROPs.

Theoretically speaking, the Radeon RX 5700 should be 310% faster than the Radeon RX 460 overall, due to its higher data rate. (explain)

Radeon RX 5700 458752 MB/sec
Radeon RX 460 112000 MB/sec
Difference: 346752 (310%)

Texel Rate

The Radeon RX 5700 should be quite a bit (about 246%) more effective at AF than the Radeon RX 460. (explain)

Radeon RX 5700 210960 Mtexels/sec
Radeon RX 460 61040 Mtexels/sec
Difference: 149920 (246%)

Pixel Rate

The Radeon RX 5700 is quite a bit (approximately 438%) more effective at anti-aliasing than the Radeon RX 460, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5700 93760 Mpixels/sec
Radeon RX 460 17440 Mpixels/sec
Difference: 76320 (438%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
