AMD’s Zen 2 CPU samples reportedly run at around 4.5GHz “generally”
Sadly, this claim does not say whether or not this means a 15% raw performance boost, a 15% increase in average IPC (performance per clock). Even so, the power consumption and heat generation of AMD’s new processors were said to be “well received”, which means that there could be plenty of thermal/power headroom for overclocking.Â
It is worth noting that this data is said to come from early CPU samples, which means that clock speeds are likely to be lower than their final retail counterparts. Even so, the 4.5GHz “general” clock speed of AMD’s first AM4 Zen 2 samples are encouraging, as this data suggests that AMD’s upcoming processors can boost beyond 4.5GHz. Improvements to AMD’s memory controller are claimed not to be as large as expected, though any positive movement in this direction is welcome.Â
AMD’s upcoming X570 series of motherboards are rumoured to release with 40 total PCIe lanes, which are shared between PCIe slots, I/O connectivity and storage interfaces (M.2/NVMe, SATA etc). X570 motherboards are also rumoured to support a large number of USB 3.1 Gen 2 ports.

Zen 2 will improve several aspects of AMD’s Zen architecture in significant ways, with the architecture doubling their floating point performance thanks to stronger AVX support. This change will allow AMD to deliver much higher performance in specific workloads, though many tasks will be unaffected by the change.Â
Generalised ??% IPC increase claims are useful when considering processors with a wide brush, but ultimately it is useless when real-world performance is always workload specific. AMD’s Ryzen 2nd Generation processors were marketed with 3% IPC gains, but in reality, the improved memory/cache latencies of AMD’s Zen architecture could deliver PC users up to 20% performance gains under the right circumstances.Â
According to Bilibili’s report, AMD’s B550 series motherboards will release two months after X570, which is rumoured to launch in July.Â
