New data from Geekbench has surfaced for Intel's unannounced “Arrow Lake Refresh”, branding the upcoming performance bump as the “Plus” series. While these chips weren't mentioned during Intel's CES 2026 keynote, the new leaks suggest that both desktop (LGA-1851) and mobile (HX) refreshes are right around the corner.
The desktop flagship, the Core Ultra 9 290K Plus (via Benchleaks), appeared on a Gigabyte Z890 Aorus Tachyon Ice motherboard paired with 48 GB of DDR5-8000 memory. The benchmark results indicate a meaningful performance uplift over the existing 285K, achieved through clock-speed increase rather than architectural changes or core-count increases. The chip maintains the 24-core (8P + 16E) layout but has a reported maximum boost frequency of 5.8 GHz. In the single-core test, it scored 3,456 points, which makes it about 8% faster than the 285K. As for the multi-core score, the upcoming CPU saw a 9% increase over its predecessor, scoring 24,610 points.
The refresh also extends to high-performance laptops and small-form-factor systems. The Core Ultra 9 290HX Plus (via Benchleaks) has been spotted in an Acer Predator Helios 18 AI (model PHN18-I71). However, unlike the 290K Plus entry, this processor wasn't running at full power, reaching a max clock speed of around 841 MHz. That's quite a bit lower than the 5.x GHz we expect from this CPU. As one would expect, the scores were abysmally low and not worth comparing with other CPUs.
Despite no official announcement at CES 2026 last week, we're expecting these chips to still be announced relatively soon. The first entries of an Arrow Lake refresh CPU date back to October 2025, and since then, we've already seen other mentions of these CPUs here and there. So it's looking increasingly like just a matter of time before they become official.

KitGuru says: Even if these CPUs won't magically make Intel relevant again, they should still offer more performance than Intel currently has.
