Zen 5 to bring 19% IPC improvement over Zen 4 according to new leak

AMD is expected to unveil its Zen 5-powered Strix Point laptop processors in June. In the meantime, the performance capabilities of an unnamed Granite Ridge chip, a high-performance desktop part powered by Zen 5, have been leaked on X by @9550pro.

The processor in question runs at up to 5.8 GHz and eats 170 W, and from this alone it becomes obvious that this could be the successor to the mighty Ryzen 9 7950X. While many fields are blurred out in the screenshot below, we can see the processor makes use of the AM5 socket just like the current 7000-series desktop Ryzen chips do.

More importantly, @9550pro appears to have unearthed this yet-to-be-announced chip's single-thread performance numbers. According to the serial leaker, the chip gets 910 points in CPU-Z's built-in single-thread benchmark. The Ryzen 9 7950X is good for around 767 points so if adjusted for the clock speed difference (up to 5.8 GHz vs up to 5.7 GHz), the new chip delivers an almost 19% higher performance per clock cycle, usually referred to as IPC. For a 16-core, 32-thread chip, an IPC uplift of that kind means a massive multi-thread performance improvement.

An earlier leak claimed that an almost 40 percentage points IPC improvement is to be expected from the new microarchitecture. That was later revealed to be an April Fool's joke. An even earlier leak mentioned the 40% figure, too.

For comparison, Zen 4 brought a ~13% IPC improvement over Zen 3.

Those still rocking an AM4 motherboard can currently get the 12-core, 24-thread Ryzen 5 5900X for $278 on Amazon.com
