Leaks suggest 19% boost for AMD’s Zen 5 Ryzen 9000 CPUs in test

Leaker claims that AMD’s CPUs have “changed a lot” with Zen 5 – “Non-x3d easily takes out zen4’s x3d”

Thanks to @9550pro, we have caught wind of some new AMD CPU leaks from baidu. If these leaks are true, gamers should prepare to be impressed by AMD’s Zen 5 based Ryzen 9000 series processor, as “Non-x3d [reportedly] easily takes out zen4’s x3d”.

With a 5,8 GHz boost clock, AMD’s Zen 5 CPUs can reportedly deliver a single-threaded score of around 910 in CPU-Z. For context, AMD’s Ryzen 9 7950X can achieve a score of around 760 in this test. That gives AMD’s Zen 5 CPU a performance boost of almost 20% in this workload. Not a bad result from team Ryzen.

Today’s leak has also stated that AMD’s “IF bus has changed a lot”, and that “the memory is very interesting”. This backs up older rumours that AMD has made major changes to its L3 cache and ring bus for their Zen 5/Ryzen 9000 series processors. These rumours suggest that AMD’s Zen 5 CPUs will feature a larger L1 cache, and faster DDR5 memory support. Additionally, Zen 5 reportedly features an L3 “Ladder Cache”, which replaces the ring-bus style cache of older Zen processors.

With AMD’s new “ladder cache”, AMD appears to be reducing core-to-core latencies and L3 cache latencies for their Zen 5 CCDs. This should result in notable performance gains in memory and cache sensitive workloads.

Another Zen 3-like moment for AMD?

If this leak is legitimate, AMD’s Zen 5 processors will likely deliver significant performance gains over their predecessors. Many are suggesting that this will be another “Zen 3-like” generation from AMD. For context, AMD’s Zen 3 architecture delivered major performance gains for AMD across a wide range of workloads. If AMD can repeat this success with Zen 5, the Ryzen 900 series will be a huge hit.
