Intel's Panther Lake SoCs have been a promising launch for gaming and professional workloads, but here's how the lineup stacks up in IPC performance.

Team Blue's newest CPU offering has been a highlight this year, at least in the consumer PC segment, as Panther Lake has shown us how capable the 18A platform has become. In our exclusive review of PTL , we dived deep into how the chip performs across synthetic and gaming workloads, but data on how P-Cores and E-Cores are stacking up wasn't available. However, a has tested out Cougar Cove and Darkmont, and the results are surely surprising.

The testing was done using SPEC CPU 2017, the go-to benchmarking suite for integer performance and widely recognized for testing factors such as branch prediction and memory latency. The reviewer uses the LPDDR5 platform on board, with WSL 2 and multiple P/E core offerings sourced from lineups like Arrow Lake and Panther Lake. On the AMD side, PTL was compared with Strix Halo Zen 5 and Zen 5c offerings, and here's how the performance stacks up:

The metric on the left is "int_rate", which measures raw throughput performance, and this is the baseline measurement for IPC performance, while the data on the right is IPC/GHz, which is relative to a baseline core and focuses on microarchitecture efficiency, which is a more effective parameter if we want to conclude PTL's core configuration performance. The results indicate that, relative to Zen 5 and Zen 5c cores, Cougar Cove delivers a 10% higher IPC, while Darkmont provides around 6%.

Intel has completely revamped its microarchitecture with Panther Lake , integrating P-Cores alongside E/LP-E cores to cater to heavy workloads where power efficiency is a priority. When we talk about IPC performance alone, sure, it isn't a huge metric to conclude on Zen 5 vs Panther Lake, but it defintely shows that microarchitectures and the advancements within them have paved the way for Team Blue to put up a solid platform.
