Intel Core i9-9900K 8 Core Flagship CPU’s Cinebench R15 Benchmark Leaks Out – Overclocked To 5 GHz Across All Cores, Massive Multi-Thread Performance
Intel Core i9-9900K 8 Core Flagship CPU’s Cinebench R15 Benchmark Leaks Out – Overclocked To 5 GHz Across All Cores, Massive Multi-Thread Performance-November 2024

The first performance results of the Intel Core i9-9900K in one of the most popular benchmarks for CPU performance have leaked out. I am talking about Cinebench R15 and the Intel 9th Generation flagship just crushes it with its top of the line multi-core performance with 8 cores and 16 threads.

Intel Core i9-9900K Flagship 8 Core CPU Tested in Cinebench R15, Scores Over 2000 in Multi-Core Test at 5 GHz Without Even Breaking a Sweat

Just a few days ago we got to see the 3DMarkTimespy score of the Intel Core i9-9900K and a day before that, we saw manyGeekbench 4 benchmarksof the entire unlocked 9th Gen processor lineup. The CPUs are still some time away from their official launch and many reviewers and overclockers already have their hands on the processors and Z390 motherboards. Some of the earlier benchmarks we got to see were posted by motherboard manufacturers themselves who forgot to pull the plug from the internet where the results got listed (accidentally).

Before we talk about the performance results, we should take a look at the Core i9-9900K CPU and its specifications.

Intel Core i9-9900K, Intel’s First 8 Core Mainstream CPU With 4.7 GHz All 8 Core Boost Frequency, Faster Than Intel’s 8086K Anniversary Edition In All Possible Ways

The Intel Core i9-9900K is the flagship SKU of the 9th Generation Core family. This will be the first mainstream desktop Core i9 part and also the first Intel chip to boast 8 cores and 16 threads. In terms of cache, the chip will feature 16 MB of L3 and will come with an Intel UHD 620 graphics chip.

The clock speeds are something to check out here, we are going to get a 3.6 GHz base clock out of the box and a 5.0 GHz boost clock in single and dual core operations. 4 core boost is rated at 4.8 GHz while 6/8 core boost is rated at 4.7 GHz. This is the highest frequency we have seen on an 8 core part across all cores. All of this is done under a 95W package so we can expect some hefty cooling solutions to go along with this chip.
