Intel Core i9-11900K vs Core i9-10900K 5.2 GHz Overclock Benchmarks Leak Out – 8 Core Rocket Lake Flagship Solely Quicker In Single-Core Apps, Lacks in Gaming & Multi-Threaded Efficiency

The Intel Core i9-11900K is now confirmed because the flagship eleventh Gen CPU. The corporate confirmed off some gaming performance numbers the place it was outpacing an AMD Ryzen 9 5900X CPU by as much as 8% however we all the time advise to take official efficiency metrics with a grain of salt. So right here we’re with the newest outcomes that had been carried out with a QS chip that eliminates the caught PCIe bug that was a problem on the ES chips. As such, the gaming efficiency you’re looking at right here must be near the actual factor.

The Intel Core i9-11900K would be the flagship eleventh Gen Rocket Lake Desktop CPU. The chip goes to function 8 cores and 16 threads. This may end 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 three.50 GHz and a lift clock of as much as 5.2GHz (1-core) & 4.80 GHz (all-core).

The chip may even function Thermal Velocity Increase which ought to ship a 100 MHz bounce within the max clock frequency. This could result in a single-core increase clock of 5.3 GHz making it the primary CPU to ever hit such a excessive frequency out of the field. Nevertheless, do do not forget that no matter utilizing the Cypress Cove cores, the Core i9-11900K will function decrease cores and threads than the Intel Core i9-10900K. That is partially as a result of backporting of Cypress Cove on the refined 14nm course of node.

The CPU is alleged to function a 1st stage energy restrict of 125W which is normal for a flagship Intel SKU and the 2nd stage energy restrict or PL2 is rated at 250W. Because of this when hitting its most marketed clock speeds, the CPU may certainly be pulling the mentioned quantity of wattage from the PSU making it one of the vital power-hungry 8-core chips ever produced. This may additionally clarify why Intel did not go 10 cores and 20 threads on its eleventh Gen lineup since it might’ve turned out to be a power-hungry monster of a chip breaking even previous the 250W energy restrict.
