AMD Zen5 CPUs Claimed To Feature 10% IPC Increase

In a post on Weibo (spotted by Wccftech), Lenovo China’s manager has hinted at AMD’s upcoming processor’s performance. He has gone on the record and claimed that Zen5 will see a modest 10% increase in instructions per clock (IPC), which is a fairly typical figure on every new CPU iteration.

Simply put, instructions per clock describe how much processing can be done on every clock cycle – the higher a processor’s IPC is, the better the overall performance on a fixed clock speed. This is also why comparing different CPU architectures, even under the same brand, is rarely useful.

Previously, Kepler_L2 (known for GPU leaks) has claimed that Zen5 is over 40% faster on single-core on SPEC workstation tests, though this can mean a single workload that is hard to represent in an all-encompassing IPC figure. While the Lenovo manager says the IPC improvement is 10%, the figures seen on Cinebench R23 are slightly higher than the value suggests. This means that some workloads may see a smaller improvement which averages the overall figure as described.

This will be the smallest IPC improvement for Zen architecture since Zen to Zen+, which only provided a minuscule 3% bump on IPC. Previous iterations have managed to achieve bigger IPC increases, with Zen4 featuring a 13% increase over Zen3, followed by 19% on the prior generation (Zen2), and 15% before that. The original Zen architecture, introduced in 2017, scored a massive 52% IPC increase over the Excavator architecture, the final generation of the infamous Bulldozer lineage of CPU architectures.

In any case, we’ll know more when AMD formally introduces the new architecture, and we expect Computex later in June this year will be where Zen5 gets revealed for the first time as an architecture.

Pokdepinion: Fairly small bump, we’ll have to see if other elements like clock speeds are improved as well.
