Radeon HD 7850 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has a core clock speed of 1375 MHz and a GDDR6 memory speed of 1500 MHz. It also uses a 192-bit bus, and makes use of a 7 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon HD 7850		130 Watts
Radeon RX 5600		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 5600 will be 92% quicker than the Radeon HD 7850 overall, due to its greater bandwidth. (explain)

Radeon RX 5600		294912 MB/sec
Radeon HD 7850		153600 MB/sec
	Difference: 141312 (92%)

Texel Rate

The Radeon RX 5600 will be a lot (approximately 220%) more effective at AF than the Radeon HD 7850. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7850		55040 Mtexels/sec
	Difference: 120960 (220%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5600 is a better choice, by far. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7850		27520 Mpixels/sec
	Difference: 60480 (220%)

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 data (measured in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface 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 higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
