Intel's flagship Core i9-12900K costs $589, 16C/24T at up to 5.2GHz

Intel's new flagship Core i9-12900K 'Alder Lake' CPU has 19% IPC increase over last-gen, and drags Intel up and away from 14nm.

Can you believe the day is here? Intel has launched its next-gen Alder Lake CPU architecture, the largest shift in Intel CPU architecture in over 10 years -- a shift into hybrid architecture, and a shift away from the problematic 14nm process node and onto Intel 7.

Intel's new 12th Gen Core "Alder Lake" range of CPUs is led by the flagship Core i9-12900K processor, which packs 16 cores and 24 threads of CPU power under its hood. We have 19% IPC improvement over the current-gen 11th Gen Core "Rocket Lake" CPUs, new hybrid-based Performance and Efficiency cores, DDR5 memory support, PCIe 5.0 support, and Intel Smart Cache architecture which shares its L3 cache with the p and e cores.

If we go from pure gaming benchmarks on the new Intel Core i9-12900K, which Intel has compared against its Core i9-11900K and AMD Ryzen 9 5950X processor -- the new Alder Lake flagship Core i9-12900K beats everything across the board in a decent spread of games including Far Cry 6, F1 2021, Crysis: Remastered, and Troy: A Total War Saga.

One of the bigger areas of improvement is in the power consumption side of things, with MT performance on the new Core i9-12900K "Alder Lake" CPU beating the pants off of the Intel Core i9-11900K. We're looking at PAR performance on the Core i9-12900K using just 65W, while the Core i9-11900K uses 250W.

That is crazy, and shows two things: the shift away from the 14nm process node to Intel's new 'Intel 7' node which is equivalent to TSMC's 7nm process node that it has had for a few years now. But when power is unleashed, so too is the performance -- with 125W pushing 30% more performance, and 241W delivering +50% more performance... and yet it still uses less power than the previous-gen Core i9-11900K processor.
