The supposed performance of AMD’s Ryzen 9 9950X is reportedly 8% faster than the Intel Core i9-15900K/Core Ultra 9 285K.

The alleged Ryzen 9 9950X’s performance is purportedly 8% swifter than the Intel Core i9-15900K/Core Ultra 9 285K.

The leaked Cinebench scores of Intel’s flagship Arrow Lake-S model are rather lackluster. These results are based on engineering samples from a late stage, and thus the final product is anticipated to exhibit slightly superior performance. The data has been effectively compiled by 포시포시, giving us insights into the performance comparison of various flagship processors, including the Core i9-13900K, the supposed Core i9-15900K/Core Ultra 9 285K, Ryzen 9 7950X, and the 9950X.

Based on the aforementioned results, the Arrow Lake-S sample surpasses the Core i9-13900K and 14900K in performance but falls short compared to the Ryzen 9 9950X. The leading Granite Ridge flagship outpaces the Core Ultra 9 285K by an estimated 8-9% in the multi-core benchmark. Given the absence of hyperthreading, this outcome appears reasonable. Additionally, it is interesting to note that the Intel Core Ultra 9 285K demonstrates an 11% performance boost over the 14900K in the same benchmark, despite lacking hyperthreading capabilities.

Historically, Cinebench results have favored AMD processors, suggesting that the retail version may fall short by approximately 10% in comparison to the Ryzen 9 9950X. Notably, Jaykihn reveals that the Core Ultra 9 285K (ES2) exhibits a 3% lead over the corresponding Raptor Lake component in single-threaded operations and an impressive 15% advantage in multi-threaded workloads (considering performance, not IPC).

The marginal 3% improvement in single-threaded performance for Intel’s processors may pose challenges in areas like gaming and other lightly-threaded tasks. If the Core Ultra 9 fails to bridge the gap with a significant 15% boost in multi-threaded performance compared to the Ryzen 9 9950X, its prospects in the single-threaded domain seem bleak, especially with only a modest 3% gain. Both SKUs were evaluated with a 250W PL2 power restriction.

The upcoming Lunar Lake mobile processors, featuring the “Lion Cove” P-core, are projected to deliver a remarkable 14% increase in IPC over Redwood Cove (Meteor Lake). Consequently, the desktop implementation of Arrow Lake-S is expected to exhibit an approximate 20% IPC enhancement when compared to its predecessors. It’s crucial to bear in mind that the Redwood Cove core in Meteor Lake was primarily a node shrink with minimal architectural modifications, essentially placing it in a comparison with Raptor Cove/Golden Cove.
