In a promising advancement for Intel’s restructured chip manufacturing techniques, the new Panther Lake System on Chip (SoC) has demonstrated the ability to closely rival Apple’s M5 processor found in the MacBook Pro during a comprehensive battery evaluation.
Intel Panther Lake Versus Apple’s M5: A Comparative Analysis
It’s essential to mention that the battery test in question set Intel’s top mobile chipset, the 18A-based Panther Lake, against the entry-level M5 processor from Apple. Despite the disparity in their respective market tiers, any progress made by Intel holds significance, especially when considering the rigorous optimizations inherent to Apple’s ecosystem.
The testing was also conducted on the new Asus 14-inch ExpertBook Ultra, an impressive addition to the Windows laptop market, which likely helped mitigate some of Apple’s advantages derived from its software-hardware synergy.
Benchmark Comparison: Key Specifications
Before delving into the battery performance test results, let’s examine how these two devices compare across crucial benchmarks:
- The Asus 14-inch ExpertBook Ultra features 32GB of RAM and a 1TB SSD, while the M5 MacBook Pro includes 16GB of RAM and a 512GB SSD.
- In terms of SSD performance, the Asus boasts read speeds of 13, 980MB/s compared to the 6, 797MB/s of the M5 MacBook Pro, based on Blackmagic speed tests.
- The ExpertBook Ultra achieved a Geekbench 6 CPU single-core score of 2, 823 and a multi-core score of 15, 449.
- Conversely, the M5 MacBook Pro recorded a single-core score of 4, 328 and a multi-core score of 17, 987 in Geekbench 6.
- For graphics performance, the Intel Arc B390 GPU in the Asus yields an OpenCL score of 50, 072.
- In comparison, the M5 MacBook Pro’s GPU scored significantly higher at 76, 601 in OpenCL tests.
Battery Test Results
Turning to the findings from the critical battery test, it took 2.5 hours of intensive usage at maximum screen brightness for the two devices to show significant results. The M5 MacBook Pro retained a residual battery charge of 40 percent, while the Asus ExpertBook Ultra had 38 percent remaining.
