For years, Intel processors have been shrouded in a confusing code – a jumble of letters that only the most dedicated tech enthusiasts could decipher. The “Y” chips, the “H” chips, a seemingly endless alphabet soup of suffixes meant to signal performance and power. Now, Intel is dramatically simplifying things with its new Core Ultra Series 3 “Panther Lake” chips, aiming to finally shed that legacy of complexity.
The change isn’t without a twist, however. While most of the confusing suffixes are gone, Intel has introduced a new designation: the “X.” What was once a Core Ultra 9 chip is now a “Core Ultra X9,” a subtle but significant shift tied to the underlying architecture of these new processors.
The new lineup of fourteen mobile processors largely abandons suffixes altogether, retaining only the “H” for high-performance mobile chips. But the “X” designation isn’t arbitrary. It highlights a key feature: a powerful graphics engine boasting 12 Xe3 Arc cores, which Intel collectively calls the Intel Arc B390.
This emphasis on graphics power wasn’t Intel’s initial plan. Retailers specifically requested a way to easily identify these high-performing chips for customers. They recognized the 12 Xe3 core configuration as a standout feature, demanding a clear visual cue on the packaging.
Beneath the surface, the Panther Lake chips initially divided into 8- and 16-core designs. Intel is intentionally remaining vague about the specific roles of each core – performance, efficiency, or low-power efficiency – mirroring the broader move away from granular specifications. All chips operate at a base thermal design power of 25W, ensuring consistent performance across the range.
The “H” series chips, however, push the boundaries further, with maximum thermal design power reaching 65 or even 80 watts for increased performance headroom. This allows for a significant boost in capability when needed.
Despite this simplification, Intel isn’t abandoning specialized chips entirely. A dedicated Core Ultra Series 3 chip for gaming is still on the horizon, bringing back the familiar “HX” suffix to signal its high-performance capabilities.
