New leaks and reports are coming before the launch of AMD Ryzen 3rd 3000 series CPUs. AMD Ryzen 3000 series CPUs will have the 7nm Zen2 architecture. AMD Ryzen 3000 series CPUs are expected to launch in Computex 2019. According to many sources, Motherboard manufacturers are already doing their test with these new CPUs from Q1 2019 for their upcoming products. These CPUs were early samples which were only supplied for internal testing and not necessarily indicate final retail performance or clock speeds.
According to data given by the Motherboard manufacturer shows that the Ryzen 3000 series CPUs will see 15 percent IPC increase over 2000 series CPUs. It is also reported that the boost frequency for these samples is reported at up to 4.5 GHz which should scale better with higher core and higher TDP parts. The newer 7nm process and other architectural improvements should allow clocks as high as 5GHz, more or less on par with Intel’s i9 processors.
It is also reported that the 3rd generation B-series Motherboard will not support PCIe 4.0 but the expensive X570 Motherboard will feature PCIe 4.0. It is expected that the AMD Ryzen 3000 series CPUs will have 40 PCIe lens but some of those lens are shared with SATA interface. X570 Motherboard will have many USB 3.1 gen 2 ports.
AMD Ryzen 3000 series CPUs will support old motherboard from B350. But it will not support A320. Any Motherboard older then B550 or X570 will need a BIOS update for new CPUs to support. The X570 motherboards will launch in July and the B550 motherboards are delayed by two months.
