AMD kept PC hobbyists waiting for the modern Ryzen 5000G “Cezanne” combination processors for a long time. Because the predecessor Ryzen 4000G with Zen-2 architecture was reserved for manufacturers of complete PCs, only the two quad-core Ryzen 3 3200G and 3400G with outdated Zen + technology remained for end customers. That is now changing with the six-core Ryzen 5 5600G for 220 euros and the eight-core Ryzen 7 5700G for 320 euros. We were able to buy the latter installed in a complete PC in advance and test it individually.
The two Ryzen types with integrated Radeon graphics are not intended as a separate second series parallel to the Ryzen 5000X without GPU, but also close some gaps in the offer. The eight-core Ryzen 7 5700G lies between the Ryzen 5 5600X (6 cores, 280 euros) and the Ryzen 5800X (8 cores, 380 euros). The six-core Ryzen 5 5600G rounds off the Zen 3 family at the bottom. The new combination CPUs run on an AM4 mainboard with an A520, B550, X570, B450 or X470 chipset and have a thermal design power of 65 watts.
The Ryzen 5000G processors for desktop PCs are closely related to the mobile processors of the Ryzen 5000U and 5000H series and use the identical 7-nanometer semiconductor die. The main innovation is the Zen 3 architecture of the CPU cores, which therefore calculate 17 percent faster with the same clock rate. Instead of two separate core complexes (CCX) with four cores each, there is now only one with eight. This eliminates the latency differences in core-to-core communication. The response times within a CCX are also significantly shorter than for a core in another CCX.
