Radeon HD 7770 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which makes use of a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 memory runs at a speed of 1500 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7770		80 Watts
Radeon RX 5600		150 Watts
	Difference: 70 Watts (88%)

Memory Bandwidth

In theory, the Radeon RX 5600 will be 310% quicker than the Radeon HD 7770 in general, because of its greater bandwidth. (explain)

Radeon RX 5600		294912 MB/sec
Radeon HD 7770		72000 MB/sec
	Difference: 222912 (310%)

Texel Rate

The Radeon RX 5600 will be much (approximately 340%) more effective at AF than the Radeon HD 7770. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7770		40000 Mtexels/sec
	Difference: 136000 (340%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5600 is superior to the Radeon HD 7770, and very much so. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7770		16000 Mpixels/sec
	Difference: 72000 (450%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, 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 worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
