A few days after the official launch, the first independent tests arrive on the web on the new AMD Ryzen 4000G APUs, desktop solutions based on Zen 2 architecture – like the Ryzen 3000 presented last year – with the addition of an integrated Radeon Vega graphics chip . In detail, the benchmarks come from the twitter channel ExecutableFix who managed to get their hands on a Ryzen 5 4650G, a 6 core / 12 thread chip that basically resumes the configuration of a Ryzen 5 3600.
The test in question, which sees Ryzen 5 4650G and Ryzen 5 3600 challenge each other, is mainly focused on gaming and the ability of the two chips to better manage the GeForce RTX 2080 Ti, a graphics card that can easily highlight any bottlenecks produced by the CPU.
From the graphs made available, you can see how the Ryzen 5 4650G is an excellent option for gaming too; however, we can not help but notice that on several occasions the new AMD APU does not succeed in achieving the performance of the Ryzen 5 3600, this despite having practically identical clock frequencies.
In the test the two processors were tested with factory settings and subsequently with 4.3 GHz overclocking; the Ryzen 5 4650G should also benefit from support for DDR4 4400 memories, while the more mature Ryzen 5 3600 stops at only 3600 MHz (settings maintained also in the various benchmarks).
In essence, with the data emerging from this test session, the new Ryzen 4000G APUs seem to offer average performance slightly lower than the Ryzen 3000 line with the same core / frequency. The motivation could be sought in the different approach practiced by AMD for the two generations of chips: the Ryzen 3000 use a solution with independent CCX for the cores, the Ryzen 4000G provide a monolithic chip and at the same time a clear cut of the L3 cache, which it drops from 32MB of a Ryzen 5 3600 to 8MB of a Ryzen 5 4650G.
These at the moment the first tests, the availability of APU Ryzen 4000G is still low and consequently we will have to wait for further tests (also on other models) to give a final judgment.
