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.
Intel's Newest Panther Lake Chips Take a Lead Over AMD's Strix Halo 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 hardware reviewer on the Chinese platform Bilibili 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.
