Intel Core i5 12400 "Alder Lake": A Great ~$200 CPU For Linux Users

Formally announced at CES, the Core i5 12400 and other Alder Lake non-K desktop CPUs are beginning to appear in retail channels. Last week I was able to buy an Intel Core i5 12400 "Alder Lake" from a major Internet retailer for $209 USD -- and one week later there remains availability during these turbulent supply chain times. The i5-12400 has wound up being a very nice processor for Linux use that exceeded my initial expectations.

Intel Core i9 12900K "Alder Lake" AVX-512 On Linux

While it was initially communicated by Intel that Alder Lake's Golden Cove P-Cores has AVX-512 "fused off", that has turned out not to be the case at least with the initial batch of processors and current BIOS/firmware configurations. If disabling the power-efficient Gracemont E-Cores, it's possible to enable AVX-512 and make use of it. Here are some initial AVX-512 benchmarks in such a configuration under Linux with the Core i9 12900K.

Linux's P-State Performance Governor Shows Unexpectedly Big Boosts For The Intel Core i9-11900K

The P-State and CPUFreq "performance" governors on Linux with desktop Intel/AMD processors can be of help for gaming and other select workloads by tending to keep the CPU clock frequencies higher than the default ondemand (CPUFreq) or powersave (P-State) governors used by nearly all Linux distributions. But with Intel's new Core i9 11900K "Rocket Lake" is a dramatic difference in power and performance between the Intel P-State performance and powersave governors than what we have seen over the years with prior generations of Intel Core processors.
