[Intel](https://www.intel.com/content/www/us/en/homepage.html)‘s comeback story just got a lot more interesting. The new **Panther Lake (Core Ultra Series 3)** chip, built on Intel’s 18A process, has come jaw-droppingly close to matching Apple’s [M5](https://technosports.co.in/?s=M5) in a real-world battery endurance test — and the Windows world is buzzing.

## Panther Lake vs Apple M5: Battery Test Results

A hands-on test by tech reviewer Vadim Yuryev pitted the **Asus 14-inch ExpertBook Ultra** (Panther Lake) against the **14-inch MacBook Pro (M5)** — both running at max 600 nits brightness for 2.5 hours of continuous heavy benchmarking.

| Device | Chip | Battery Left After 2.5 Hrs |
| --- | --- | --- |
| Asus 14″ ExpertBook Ultra | Intel Panther Lake (18A) | **38%** |
| Apple MacBook Pro 14″ | Apple M5 | **40%** |

Just a **2% gap**. That’s not a typo.

For context, Intel laptops were notorious for draining fast. PCWorld’s review of the Asus Zenbook Duo found up to **22–28 hours** of real-world battery on a single screen — a first for Windows laptops at this performance level.

## Why This Is a Big Deal

Apple’s M-series chips have been the gold standard in power efficiency since the M1 in 2020. For Intel — running the x86 architecture, which has historically consumed more power — to nearly match ARM-based Apple silicon is genuinely remarkable.

According to Tom’s Guide, Intel has essentially made an x86 chip behave like an ARM chip, without sacrificing Windows app compatibility. That’s a tradeoff Apple can’t offer.

Also worth noting: Panther Lake leads in **integrated GPU gaming performance** — the Xe3 GPU scored 5,883 vs the M5’s 5,077 in 3DMark Steel Nomad Light — making these laptops surprisingly capable for light gaming.
