Multiple leakers on Twitter/X have posted screenshots or pictures of Intel's upcoming Core i5-14600K CPU and it appears that some earlier rumours about this specific SKU weren't entirely accurate. It was believed that the Core i5-14600K was to get a core bump over the Core i5-13600K, but apparently this isn't the case, if the new leaks hold true. However, it also appears that the CPU will boost higher than expected, as earlier rumours suggested 5.3 GHz max boost clock and now it appears it'll go all the way up to 5.5 GHz, which is still lower than its Core i7 and Core i9 peers. The i5 also lacks Intel Turbo Boost Max Technology 3.0, so it won't be possible to squeeze some extra performance out of this chip without overclocking it the good old fashioned way.

@9550pro posted a screenshot of CPU-Z in Chinese showing the Core i5-14600K running in a Gigabyte Z790 Gaming X AX motherboard, but it's unknown what the rest of the system configuration was. However, it does show the CPU having a clock multiplier ranging from 8 to 55, confirming the 5.5 GHz max CPU clock speed. @wxnod posted a picture of an MSI Z690 Edge TI WiFi DDR4 motherboard with a Core i7-14700K paired with 16 GB of DDR4 memory running at 4600 MHz on Gear 1, which in itself is a feat, although it's unknown if this was stable. The CPU was shown as running at 6.3 GHz, which is most likely a manual overclock of the CPU, as the Core i7-14700K isn't expected to be a 6 GHz plus part. We're getting close to the launch of Intel's 14th gen Core processors, so we won't have to wait too long to find out the full specs of these CPUs.

Update 07:17 UTC: Twitter/X bot Benchleaks has found some Geekbench results for the Core i5-14600K which @harukaze5719 made a nice graph of that we've added below. This suggests that Intel has managed to eke out quite a bit of extra performance from these "refreshed" CPUs.
