Intel (NASDAQ: INTC) has announced its full line-up of 11th Gen 'Rocket Lake' processors, which include models such as the Core i9-11900K, Core i7-11700K and Core i5-11600K. Sadly, the performance is still under embargo for a few more weeks, but today we can run through the pricing, specifications and models that will be released and reviewed shortly. Rocket Lake and its underlying microarchitecture, Cypress Cove, is the company's first new desktop CPU architecture in five years. Of particular interest to enthusiasts and gamers are the three key K-series unlocked models and the the Core i9-11900K will retail for $539, the Core i7-11700K for $399 and Core i5-11600K for $262. Starting with the flagship, the Core i9-11900K has eight cores and 16 threads, which is two fewer cores than the Core i9-10900K. The reason for this is that the Cypress Cove architecture used in the new CPUs is based upon the new Sunny Cove architecture used in its 11th Gen mobile 10nm CPUs, but scaling this up to more powerful desktop parts didn't quite work out, requiring some tweaking and a backport of the design to a 14nm process. Apart from higher power consumption than a 10nm part, a side effect was that a 10-core part proved to be unviable in a more powerful desktop CPU format, so the company was forced to reign things in to eight cores instead. This will likely hand an advantage to AMD, which offers up to 16 cores on the mainstream desktop, at least in multi-threaded workloads, but Intel is pushing some very high performance increase claims for Rocket Lake, with up to 16 percent better performance in games and a 19 percent IPC improvement, which aren't far off the gains AMD claimed for Zen 3 over Zen 2 Ryzen CPUs. The pricing appears to be competitive too. The Core i5-11600K will have a launch price (USD 1K units) of $262, which nearly identical to the launch price of its predecessor, the Core i5-10600K and around $40 cheaper than the Ryzen 5 5600X. The Core i7-11700K is also an eight-core, 16-thread part, but with lower frequencies than the flagship and could offer similar performance for less cash, with a launch price of $399, which is just $20 more than the launch price of its predecessor, the Core i7-10700K. Finally, the Core i9-11900K, which will have a peak boost frequency of 5.3GHz and all-core frequency of 4.8GHz, will have a launch price of $539, which is around $60 more than the Core i9-10900K. The Core i9-11900K is interesting as it has two fewer cores than the Core i9-10900K, which means that it will need to offer significantly more performance per core to offer similar value, especially when it comes to multi-threaded applications. It's also likely that the Core i9-11900K is a highly-binned CPU that's capable of higher frequencies than the Core i7-11700K, so might be a favorite for overclockers or those looking for the absolute best performance in games. It's also worth noting the inclusion of 'KF' models.
