Leaked benchmarks of the Intel Core i9-11900K clocked at 5.3 GHz reveal PCIe issues and multi-threaded performance that falls behind AMD Ryzen.
Yesterday, benchmarks for an engineering sample of the Intel Core i9-11900K processor leaked online. Tech outlet ChaoWanKe got their hands on a pre-release version of the rare chip and tested it with a relatively weak GeForce GTX 1660 Ti graphics card. It's currently unclear whether this specific GPU is to blame for the processor's built-in PCIe controller running only at PCIe 1.1 instead of stepping up to the card's native PCIe 3.0:
There is a small chance the processor couldn't wake the PCIe controller from its idle state, leaving it stuck in a power-saving mode.
Either way, this issue could have severely impacted the gaming benchmarks, so take these results with a healthy dose of skepticism.
Fortunately, ChaoWanKe's testing of the Intel Core i9-11900K wasn't limited to games. Let's look at some application and synthetic benchmarks:
Running at 5,300 MHz, the new chip comfortably beat its predecessor, the 10900K, in CPU-Z's single-threaded test. However, due to the obvious core-count disadvantage (8 cores versus 10), it couldn't replicate that success in multi-threaded tests. Its single-thread lead over the Ryzen 9 5900X is also quite narrow, meaning we shouldn't expect Intel's new chip to completely dominate AMD's 8-core competitor.

⤢ ВІДКРИТИVideo encoding shows more of the same. The 11900K has only eight cores, making it tough to compete with its predecessor, the 10900K, let alone AMD's 12-core competitor, the Ryzen 9 5900X.
Finally, let's take a look at the gaming benchmarks:
The PCIe 1.1 limitation heavily skewed these results, so they don't reflect real-world performance at all.
