The base clock runs at 3.2 GHz, which is lower than the 9.9 GHz you mentioned.
It really doesn't matter. All CPUs tend to increase speed to near their maximum, and the 12900K has both P cores and E cores, so it's clear you're asking about the P cores.
Only the base clock spec exists to let OEMs market CPUs with inferior coolers
I thought it was due to them lowering RMAs. Only the poorest silicon from Intel operates at full capacity.
I kind of doubt that. I haven't had an Intel system or known of any that couldn't reach their default turbo boosts when adequately cooled. And they will run at max turbo (well, all-core max turbo anyway) out of the box if adequately cooled; no way to even know if something was ever overclocked if you don't tell them. And most people running their systems on default won't. The only times I've ever seen a chip run below their all-core turbo is after PL2 runs out or thermal throttling....in which case for OEMs is like most scenarios
I noticed they didn’t activate the turbo boost, but the issue lay with the motherboard rather than the CPU. This was my Hero X board. The i7 8086k was overclocked from the start and wasn’t tested with its original settings. After converting it to a productivity setup last month, I left it stock and it failed to reach its boost frequency. When I moved it to an Aorus Ultra Z390, everything worked fine. I’d have preferred more time on that but needed to keep the system operational for work. The Z390 was part of my bench setup with my older i7 8700k, which only handled its boost and didn’t impress me.
Well they're really not going to hit the single core boost, if that's what you mean. But 4.3ghz all-core is what you'd expect from an 8700k/8086k. Even the 8700 non-K will also do 4.3ghz all core. But they aren't going to be running at 3.7ghz. This is a motherboard issue as you noted, not the chip. I have my 10900K to do 5.3ghz on up to 4 active cores.....it rarely ever gets there. Sometimes in very lightly threaded tasks, and benchmarks, it will. But most of the time it chills at the 7+ core active turbo that I specified, which is 5.1ghz. Here's my desktop usage (current, minimum, maximum, average)
On standard configurations, many Asus boards align turbo power limits with the Intel TDP value—just 95W for the 8086K. Your Gigabyte board probably allows unlimited turbo settings to boost performance. This approach enhances the board’s appearance in reviews. Adjusting the BIOS to the highest limit, typically 4095W, ensures the CPU can utilize maximum turbo. The base clock of an Intel processor isn’t very useful, as the chip is built to leverage turbo boosts. When using Windows power plans like High Performance or Ultimate Performance, the CPU will run at full turbo speed even when idle, depending on your preference.
