There is a lot of fo excitement around the up and coming Ryzen 3000, with the help of the reduced fabrication process size, down to 7nm. There have been many claims of a dramatic IPC increase as well as core count, going up to the Ryzen 9 3800X with 16 cores and 32 threads.
In one of the last performance leaks, it was claimed that the AMD demo showing the 3rd gen Ryzen chips vs the Intel i9-9900K was power limited by 30-40% and if it was not there would have been a performance advantage of around 10-20%.
A new leak from a Chinese site Bilibili, claims that motherboard manufacturers have engineering samples of mainstream Ryzen 3000 processors in the four to eight core territory. With a launch date in less than three months I would have said this part is a given.
The user then goes on to state that while final clock speeds haven’t been established, the CPUs reliably run at 4.5 GHz and outperform previous parts by 15%, while having impressively low thermal output and power requirements.
The architectural shift has seen a vastly improved execution pipeline, double the core density, improvements to floating point bandwidth, better branch prediction, improvements to instruction pre-fetching etc.
In general, this leak doesn't reveal anything new, but is another source confirming the performance of the new Ryzen 3000 is going to be fantastic.
Many of the new X570 motherboards that are arriving in July have either been leaked, or teased directly by motherboard manufacturers. The new X570 will likely feature up to 40 PCIe 4.0 lanes, powering eight USB 3.1 Gen2 ports in addition to the regular expansion slots, SATA, and USB 2.0.
The affordable B550 motherboards will likely launch a few months later with cut down specs and it is unclear if these will support PCie 4.0 or now.
