Well, the latest benchmarks of Intel's Core i9-11900K 8 Core Rocket Lake CPU have just leaked out by a Chinese TechTuber and the results are a mixed bag for the 11th Gen flagship. The difference between these and the earlier benchmarks is that the previous results were evaluated using an ES chip while the latest benchmarks are performed on a QS chip which should be close to the retail unit.
Intel Core i9-11900K vs Core i9-10900K 5.2 GHz Overclock Benchmarks Leak Out - 8 Core Rocket Lake Flagship Only Faster In Single-Core Apps, Lacks in Gaming & Multi-Threaded Performance
The Intel Core i9-11900K is now confirmed as the flagship 11th Gen CPU. The company showed off some gaming performance numbers where it was outpacing an AMD Ryzen 9 5900X CPU by up to 8% but we always advise to take official performance metrics with a grain of salt. So here we are with the latest results that were done with a QS chip that gets rid of the stuck PCIe bug that was an issue on the ES chips. As such, the gaming performance you are looking at here should be close to the real thing.
Intel Core i9-11900K 8 Core & 16 Thread Rocket Lake Desktop CPU Specifications
The Intel Core i9-11900K will be the flagship 11th Gen Rocket Lake Desktop CPU. The chip is going to feature 8 cores and 16 threads. This will result in 16 MB of L3 cache (2 MB per core) and 4 MB of L2 cache (512 KB per core). The CPU has a base clock of 3.50 GHz and a boost clock of up to 5.2GHz (1-core) & 4.80 GHz (all-core).
The chip will also feature Thermal Velocity Boost which should deliver a 100 MHz jump in the max clock frequency. This should lead to a single-core boost clock of 5.3 GHz making it the first CPU to ever hit such a high frequency out of the box. However, do remember that regardless of using the Cypress Cove cores, the Core i9-11900K will feature lower cores and threads than the Intel Core i9-10900K. This is partially due to the backporting of Cypress Cove on the refined 14nm process node.
The CPU is said to feature a 1st stage power limit of 125W which is standard for a flagship Intel SKU and the 2nd stage power limit or PL2 is rated at 250W. This means that when hitting its maximum advertised clock speeds, the CPU could indeed be pulling the said amount of wattage from the PSU making it one of the most power-hungry 8-core chips ever produced. This might also explain why Intel didn't go 10 cores and 20 threads on its 11th Gen lineup since it would've turned out to be a power-hungry monster of a chip breaking even past the 250W power limit.
