AMD Ryzen AI 9 300 Posts a 20% Performance Upgrade with Both Graphics and CPU Over Previous Gen
The top-spec AMD Ryzen AI 9 300 series "Strix Point" processor, the Ryzen AI 9 HX 370, is expected to post a 20% performance improvement over both the CPU and integrated graphics fronts, over its predecessor, the Ryzen 9 8945HS "Hawk Point," according to leak by Golden Pig Upgrade. On the CPU front, the HX 370 packs a 12-core/24-thread CPU based on a combination of four "Zen 5" and eight "Zen 5c" cores. The single-thread performance gains on the basis of the "Zen 5" microarchitecture's generational IPC increase, besides higher clock speeds; while the multithreaded performance increases on account on more cores. This performance increase isn't linearly scaling with the 50% increase in core-count.
On "Hawk Point," all eight cores are "Zen 4," capable of boosting to high frequencies, with two of them being marked as CPPC preferred cores, capable of boosting the highest. On "Strix Point," however, only four cores are based on the "Zen 5" architecture and capable of boosting to high frequency bands; while the other eight are "Zen 5c," which don't boost as high. While the IPC of "Zen 5c" is identical to "Zen 5," the fact that it doesn't boost as high, means that the generational multithreaded performance gain from the core-count increase is expected to be closer to 20%, with Golden Pig Upgrade talking about a Cinebench R23 nT score of over 20000 points, with "Hawk Point" scoring around 16000 points.
