Intel Core Ultra 5 235HX, mid-range engine in a high-end chassis

The Intel Core Ultra 5 235HX is Intel’s latest mid-range offering in the mobile high-performance processor segment – embedded in the HX series, the very platform on which Intel usually unloads its brute notebook behemoths. But anyone expecting a tiger here is more likely to get a hefty hangover – at least in terms of overall performance in relation to power consumption.

The chip is based on Intel’s new modular architecture codenamed “Arrow Lake-HX”, manufactured with a mix of TSMC and Intel’s own nodes. At its heart is a 14-core design, divided into 6 performance cores (P-cores) and 8 efficiency cores (E-cores). Depending on the load scenario, these clock up to 5.1 GHz (P) or 4.5 GHz (E), which sounds quite impressive in the notebook segment – on the data sheet. Under real thermal conditions, things naturally look more different. The L3 cache is 26 MB, the L2 cache is 24 MB – that’s decent and supports fast load changes in multi-threading mode.

The design also comes with a dedicated NPU, which can be interpreted as “AI-ready” – or simply as Intel marketing vocabulary that is written into the data sheet so as not to look completely empty against AMD’s Ryzen AI series. The iGPU? A slimmed-down version with 3 Xe cores. That’s enough for office work, but no more than a placebo entry for gaming on integrated graphics. Benchmarks show a mixed picture. In Geekbench 6.4, the Core Ultra 5 235HX achieves around 4708 points in single-core and 40122 points in multi-core – a typical value for the upper mid-range. The comparison with its predecessor is more interesting: According to unofficial PassMark figures, the 235HX outperforms the Core i5-14500HX by up to 38% in multi-core – that sounds like progress, but is quickly put into perspective in view of the full TDP of 55 watts base and a maximum boost consumption of up to 160 watts. For a mid-range chip, this is a pretty high power consumption, which quickly turns it into a hot air cannon in thermally poorly designed notebooks.

What does this mean for the market? Intel places the 235HX significantly below the i7 and i9 offshoots of the HX series, but still in a thermal corset that is actually intended for top models. Here, the Ultra 5 235HX almost looks like a compact diesel in an off-road vehicle – solid, but with exaggerated expectations and a consumption that does not match the mid-range positioning. AMD counters with more efficient Phoenix or Hawk Point chips, which offer similar performance with better energy efficiency – a clear indication of Intel’s ongoing struggle to regain ground in the mobile segment. Strategically, the Core Ultra 5 235HX is a signal process: Intel is showing that the Arrow Lake platform is scalable – with advanced manufacturing, chiplet designs, Foveros packaging and AI integration. However, the cost structure, thermal performance and GPU weaknesses also show that this chip is not a jack of all trades, but a bridge between old strengths and new hopes. Not a disaster, but not a liberation either.
