7 nm AMD Ryzen 7 4800U is as fast as the 14 nm Core i9-9880H and at half the TDP, but there's a huge catch (Image source: AMD)
7 nm AMD Ryzen 7 4800U is as quick because the 14 nm Core i9-9880H and at half of the TDP, nonetheless there would possibly be a massive rep (Characterize source: AMD)

Can an 8-core 25 W cTDP Ryzen 7 4800U outperform the liked 8-core 45 W Core i9-9880H? They’re mighty closer than what you can well judge as a minimum until you originate up stressing the Ryzen processor over very long classes.

The crown to AMD’s most up-to-date Zen 2 U-sequence lineup is the Ryzen 7 4800U. Now not like every other processor in its stack, the octa-core Ryzen 7 4800U is valuable for integrating 16 simultaneous execution threads within a 15 W to 25 W power envelope in comparison with simplest 8 threads on most other U-sequence processors. Intel within the intervening time has no equal in this regard until you originate up shifting up to its 45 W Core H sequence CPUs like the Ninth gen Core i9-9880H or 10th gen Core i7-10875H. This begs the ask: How does the Ryzen 7 4800U compare to the more power-hungry Core i9-9880H?

It seems, the Ryzen CPU can originate plenty closer to the Core i9-9880H than on the origin expected based on our time with the 14-plod Lenovo IdeaPad 14 Ultrabook. All examined benchmarks like CineBench, Blender, 7-Zip, GeekBench, HWBOT, and LibreOffice ticket single-digit proportion facets between the Ryzen 7 4800U in our Lenovo and the moderate Core i9-9880H in our database. Irrespective of the method you decrease it, these consistent outcomes are spectacular for AMD especially when pondering the mighty bigger efficiency-per-watt at play.

Or no longer it is no longer a dwelling bustle for AMD, nonetheless, because the limits of the Ryzen 7 4800U are published when running extreme loads for long classes with out a cooldown length in between. When running CineBench R15 xT in a loop, as an instance, the initial excessive come by of 1620 facets would fall and stabilize to about 1210 facets by the fifth or 6th loop. This 25 p.c dip in efficiency is steeper than on any Core i9-9880H computer computer we own now examined to this level.

The CPU efficiency fall would possibly well maybe also be observed in further detail when running Prime95 as smartly. Clock rates would enhance to three.5 GHz to 4.3 GHz for simplest the first few seconds earlier than step by step falling and indirectly stabilizing at 2.3 GHz and at a core temperature of 60 C to 65 C. In another case, core temperature would be smartly over 90 C based on HWiNFO to counsel that the processor would possibly well maybe potentially bustle faster on bigger computer computer designs.

For the reason that Ryzen 7 4800U is so original, we are going to own to wait and glimpse what other OEMs can finish with the processor originate air of Lenovo. Its configurable TDP ought to permit for a wide vary of appropriate chassis designs and thus a wide vary of efficiency variations between items.

After graduating with a B.S. in environmental hydrodynamics from the College of California, I studied reactor physics to change into licensed by the U.S. NRC to operate nuclear reactors. There is a striking stage of appreciation you set aside for day to day shopper electronics after working with contemporary nuclear reactivity systems astonishingly powered by computers from the 80s. After I’m no longer managing day-to-day activities and US review articles on Notebookcheck, you are going to be ready to rep me following the eSports scene and the most up-to-date gaming data.
