Intel's Alder Lake Reviewed: 12th Gen Core Processors Bring Fight Back To AMD

MojoKid writes: After months of speculation and early look teases, Intel's 12th Gen Core processors are finally ready for prime time. Today marks the embargo lift for independent reviews of Alder Lake and it's clear Chipzilla is back and bringing the fight again versus chief rival AMD. Intel 12th Gen Core processors incorporate two new CPU core designs, dubbed Efficiency (E-core) and Performance (P-core). In addition to this new hybrid core architecture, 12th Gen Core processors and the Z690 motherboard chipset platform also feature support for the latest memory and IO technologies, including PCI Express Gen 5, DDR5, Thunderbolt 4 and Wi-Fi 6E. The new Core i9-12900K features a monolithic, 16-core (24-thread) die with 8 Performance cores and 8 Efficiency cores, while the Core i5-12600K has 10 cores/16-threads, comprised of 6 P-cores and 4 E-cores. Alder Lake E-cores don't support HyperThreading but P-cores can process two threads simultaneously while E-cores can manage only one, hence the asymmetric core counts.

In the benchmarks, the 16-core Core i9-12900K doesn't sweep AMD's 16-core Ryzen 9 5950X across the board in multi-threaded tests, but it certainly competes very well and notches plenty of victories. In the lightly-threaded tests though, it's a much clearer win for Intel and gaming is an obvious strong point as well. Alder Lake's performance cores are as fast as they come. The $589 (MSRP) 16-core Core i9-12900K competes well with the $750 16-core Ryzen 9 5950X, and the $289 10-core Core i5-12600K has a lower MSRP than a $299 6-core Ryzen 5 5600X. The new Core i5's power and performance look great too, especially when you consider this $289 chip outruns Intel's previous-gen flagship Core i9-11900K more often than not, and it smokes a Ryzen 5 5600X.
