Intel's new laptop chip just embarrassed desktop CPUs

Okay so I saw this benchmark and had to share. Intel's upcoming Core Ultra 9 290HX Plus just showed up on PassMark, and honestly? This laptop chip is making desktop processors look bad. We're talking single-threaded performance that's basically matching Intel's flagship Core Ultra 9 285K desktop CPU. In a laptop chip. That's wild.

Here's what struck me about these numbers. This mobile processor isn't just beating other laptop chips – it's crushing them. But the real kicker is how it stacks up against desktop parts. When a chip designed for laptops can nearly match the single-threaded grunt of Intel's top desktop CPU, you know something interesting is happening. The 290HX Plus posted scores that would make most desktop builds from even a year ago look dated.

Now I'm really curious about the full Arrow Lake mobile lineup coming later in 2026. If this is what the high-end mobile chip can do, Intel might actually have something special brewing. The desktop Arrow Lake parts we've been testing have been solid, but nothing that made me go "wow" like this.

What I really want to know is how this translates to real-world performance. Benchmarks are one thing, but can this chip maintain these speeds when it's crammed into an actual laptop dealing with thermal limits? And more importantly – what's the battery life going to look like? Because if Intel managed to deliver desktop-level performance without turning laptops into three-hour paperweights, that's the real story here.

For now though, color me impressed. The 290HX Plus looks like it could shake up the whole "desktop replacement" laptop category in 2027.
