The first tests of the new Ryzen 4000

AMD’s new generation of mobile processors is still under development, but the first results have already appeared in the 3DMark and User Benchmark benchmark databases.

Datamainers TUM_apisak and rogame managed to find references and test results for new AMD crystals before release. According to the information received, the transition to the new 7 nm process technology allowed us to achieve a serious leap in the performance of the integrated graphics of the Ryzen 7‑4800U and Ryzen 7‑4700U mobile processors.

These are energy-efficient systems-on-a-chip with a claimed heat output of only 15 watts, designed for use in compact and thin laptops. They are equipped with a second-generation Vega graphics accelerator, the performance of which for each core was raised by 59%. At least that is what Robert Hallock of AMD reports in response to a question about why the new processors use the old Vega cores rather than the more modern Navi.

We did not agree on [production] schedules. But each Vega computing unit in the 3rd generation models is 59% faster than in the 2nd.

When comparing the integrated graphics of the new Ryzen 7 and Intel Iris Pro in User Benchmark , AMD is superior to 34% in the overall standings.

Moreover, the new integrated Radeon graphics is comparable and even slightly ahead of the discrete chip for compact notebooks GeForce MX250. In tests of Notebookcheck, a laptop with such a video card proved to be the best option for Dota 2 (63 fps at maximum settings) and produced a playable 38 fps in The Witcher 3 on Medium (albeit in HD resolution). This level of performance was previously unattainable for integrated graphics.

When comparing the two top-end Ryzen 7 mobiles with the flagship Intel Core i7‑1065G7, the results were in favor of the “red ones” even though formally the Ryzen 7‑4700U is considered a lower-level chip. The biggest differences are observed in the video subsystem, Vega confidently bypasses Intel Iris Pro.

Compared to the more powerful 45-watt i7-10750H, the lag of the Ryzen 7-4800U was only about 15%, although formally the difference between U and H chips should be very significant.

Among the 3DMark 11 data, we found different Ryzen 7‑4800U test results. Since the difference between them is up to 20.6%, it can be assumed that this chip will have two revisions with a heat packet of 15 W and 25 W at the discretion of the manufacturer of a particular device.

Compared to the current generation Ryzen 7‑3700U, the difference with the 4800U is 25% in the graphics subsystem and up to 65% in the overall performance rating. The reason for this is a larger number of cores / threads.

We remind you that the results of synthetic benchmarks and a comparison of the characteristics allow us to draw only approximate preliminary conclusions about the real performance of the devices. Announcements and the release of the first laptops with the new Ryzen 7 processors 4000 series are expected until the end of the 1st quarter of 2020.

We will be happy to hear your thoughts
