In a recent development, Intel’s Core Ultra “Meteor Lake” processors have exhibited substantial performance and efficiency improvements through the deployment of updated BIOS firmware. Initial reviews by UltrabookReview revealed that the pre-release BIOS firmware equipped with Meteor Lake laptops inadvertently led to performance bottlenecks due to inefficiencies in power delivery.
Acknowledging the issue, Intel is actively collaborating with its partners to rectify the situation. ASUS has promptly responded by releasing a UEFI firmware update (version 203), resulting in noticeable enhancements in both performance and efficiency.
Benchmark results provided by UltrabookReview’s Andrei Girbea demonstrate a noteworthy 12.5% increase in Cinebench testing performance when upgrading from BIOS version 201 to the latest version 203. The author indicated ongoing efforts to compile data for various other applications.
Girbea’s observations on the Cinebench R23 scores are as follows:
- BIOS 201: CPU 12357 pts (best run), CPU 11342 pts (10 min loop test), CPU Single Core 1751 pts (best run)
- BIOS 203: CPU 13873 pts (best run), CPU 12132 pts (10 min loop test), CPU Single Core 1761 pts (best run)
These findings align with a previous review by renowned hardware leaker Golden Pig Upgrade, which also identified an “inefficient power delivery” system. The review noted a scheduling problem related to early power measurement, with significant improvements observed in power draw and overall performance after applying the latest firmware update.
Given that Intel’s Core Ultra “Meteor Lake” CPUs represent a novel chiplet design, ongoing BIOS firmware updates are anticipated to introduce further tuning and optimizations. Intel is reportedly working on a new driver addressing CPU/GPU performance in lower power modes, expected to be rolled out gradually in Q1 2024 as Meteor Lake laptops become more widely accessible to consumers.
