Intel Core Ultra 7 270K Plus vs Intel Core Ultra 9 285K: Comparison
Core Ultra 7 270K Plus vs Core Ultra 9 285K p-core boost clock compared
The first real difference is p-core boost clock: Core Ultra 7 270K Plus 5.4 GHz against Core Ultra 9 285K 5.5 GHz. Measured rather than claimed: in Blender Cycles (CPU) the Core Ultra 7 270K Plus returns 611 against 562 over 20 runs, a 8% lead.
Core Ultra 7 270K Plus vs Core Ultra 9 285K: which one fits your build
The Core Ultra 7 270K Plus is the one to take for users who want DDR5-7200 memory support and 24 PCIe lanes. The same goes for desktop builders on LGA 1851 wanting 24 cores (8 P-cores and 16 E-cores) and 36 MB of L3 cache. Avoid it for buyers on a tight power budget, as the base power is 125 W and max turbo reaches 250 W. Take the Core Ultra 9 285K for content creation and heavily multi-threaded productivity desktop builds wanting Intel's newest, most power-efficient flagship. It is not the one for buyers prioritizing maximum gaming frame rates, AMD's 3D V-Cache chips generally lead in gaming-specific benchmarks. Our rating of the Core Ultra 9 285K (8.5/10): the Intel Core Ultra 9 285K is a fast, more efficient flagship for multithreaded work, though its gaming speed trails the best AMD chips.
Where the two are identical
Where they agree, they agree completely, total cores, performance cores, efficiency cores, total threads and p-core base clock included, so the decision does not turn on any of those. They match on 11 further specifications as well.
Frequently asked questions
Do the Core Ultra 7 270K Plus and Core Ultra 9 285K differ on socket?
Yes. Socket reads LGA 1851 on the Core Ultra 7 270K Plus versus FCLGA1851 on the Core Ultra 9 285K.
Is the E-Core Base Clock the same on the Core Ultra 7 270K Plus and Core Ultra 9 285K?
It is. Both are listed at 3.2 GHz, so it is not a reason to pick one over the other.
