If you’re planning on getting yourself one of Intel’s Core Ultra 200 LGA1851, also known as Arrow Lake, desktop CPUs, you may want to hold off for a while after its launch, on account of a supposed and newly discovered problem. Specifically, it’s the location of the hot spot of the new processors.
The issue was brought up over at the Overclock3D forum by none other than renowned overclocker, Roman “Der8auer” Hartung, who said that the hot spot for the new LGA1851 processors was “a bit further North” on the die than it was on the LGA1700 chipset.
“The hot spot on LGA1851 is quite a bit further north than it was on 1700. This means for ideal cooling a shift of the cooling center is required to fight the hot spot. It also means that rotating the block 180° would harm the performance. For us it would be the easiest to have the in port north and out in the south orientation.”
For the uninitiated, desktop CPUs over several generations tend to have different hot spot placements. This is due to the position of the most compute-intensive elements, which again, is the prime suspect of where these hot spots occur. For example, AMD’s AM5 chipsets have their hot spots situation south of the chip, primarily due to location of their CCDs.
Another reason for the hot spot’s shift up north is because Intel’s LGA1851 or rather, Arrow Lake architecture, marks the chipmaker’s departure from its monolithic design and its embrace of its own Foveros packaging, with the utilisation of a multi-tile design.
