At the launch of the AMD Ryzen 4000 APUs, it was already possible to see on the benches that AMD provided a significant increase in performance compared to the second generation (Picasso). Both generations have some similarities Vega GPUs at 7 nm (The new generation was expected to already have RDNA2 footage), although Robert Hallock of AMD has already explained the reason for this decision.
Because the schedules did not match. But each Vega CU on 3rd Gen Mobile is 59% faster than 2nd Gen

The answer is that the opening agendas are inconsistent, and yet this third generation has 59% more performance than before. With all that in mind, we have to remember that Lisa Su, CEO of AMD, has already confirmed that we will see APUs powered by Navi GPUs next time

Let's move on to the benches. In the 3DMark database, some results obtained from the 4800U and 4700U APUs were damaged:
On 3DMark11, the Ryzen 7 4800U is a 10% faster than the Intel Core i7-1065G7 with Iris Pro graphics. Ryzen 7 4700U also exceeds Intel processor by 2%, though chip low leopard
In CPU physics testing the Ryzen 7 4800U is up to 30%, although this is due to the high processing speed and the sheer number of cores and process threads. However, on the other bench we see that only Intel Core i7-1075H surpasses Ryzen 7 4800U by 15% even though Intel's processor has more than 45% speed on its tracks, and looks at the data, your TDP tripled
We also have another benchmark showing two Ryzen 7 4800U performance results, showing an advantage over Intel processor of 20% in graphics and 7% in CPU performance, which could indicate that the processor has an I-25W cTDP architecture ( TDP).
Compared to the Ryzen 7 3700U procelsadaor, the 4800U has more than 25% performance and 65% CPU performance, all very well compared to previous Picasso APUs. Going back to the graphic benches, we can see the same effect as the integrated Vega GPUs that eliminate the Iris Plus graphics with a 34% more performance.
It's clear that AMD did a fantastic job with its upcoming Ryzen 4000 APUs, and that they still use second-generation Vega footage at 2 nm, so we can expect something good performance results when using the rDNA2 construct.
