AMD unveils Ryzen 4000G desktop processors

LONDON: AMD’s desktop APUs lagged behind the mobile offerings and were still using Zen+ cores. That is changing as of today with the announcement of the Ryzen 4000G series, which upgrade to the 7 nm Zen 2 chiplets that we’ve seen in the new mobile APUs.

The CPUs range from quad-core setups to octa-core, all with hyper threading. Note that for each Ryzen 4000G APU there is a “GE” version that has a 35 W TDP instead of 65 W (at the cost of reduced base and turbo clock speeds, of course).

The move from Zen+ to Zen 2 is massive – based on Cinebench tests, the 4000G series offers up to 2.5x better multi-threaded performance compared to the 3200G and 3400G. Against an Intel Core i7-9700, the new Ryzens offer up to 5% better single-threaded and up to 31% multi-threaded performance (again, going by Cinebench scores).

The new Radeon GPU is much faster than the basic Intel offerings too, up to 202% than the UHD Graphics 630 inside the i7-9700 (based on 3DMark Time Spy). Compared to the 3400G, however, GPU performance is up only 6%.
Like their mobile counterparts, these APUs have eight PCIe 3.0 lanes.
