Upcoming Intel Core i5-12400 processor may be an energy-efficient powerhouse

The upcoming Intel Core i5-12400 processor was benchmarked ahead of its January 2022 launch, and the results are very promising for this midrange CPU.

The benchmarks show that the new Intel Alder Lake release can stand its ground in terms of performance while also providing great energy efficiency.

Igor’s Lab tested the processor for gaming purposes, and the testing returned good results. The new CPU is based on a smaller version of Intel’s new Alder Lake-S silicon, called H0. Unlike many other Alder Lake processors, this one comes with only six Golden Cove (performance) CPU cores — it doesn’t feature any Gracemont (efficiency) cores. The CPU has a base clock speed of 2.5GHz and can be boosted up to 4.4GHz in turbo mode.

Intel Core i5-12400 has a base power of 65 watts and reaches up to 117W in turbo mode — this value is referred to as maximum turbo power (MTP). Testing revealed that the processor should offer fantastic energy efficiency while performing well in gaming.

In the benchmarks, Intel’s new Core i5-12400 was tested in several games and then compared to currently existing CPUs. It performed similarly to the AMD Ryzen 5 5600X in several titles, but it also outmatched the Ryzen in more than one test.

It also offered better gaming performance than the previous generation of Intel processors. Compared to the Rocket Lake Core i7-11700K CPU, the new Alder Lake chip offered greater numbers at a significantly lower power usage. It’s worth noting that the Rocket Lake CPU is an 8-core, 16-thread chip.

The benchmark was performed by Igor’s Lab on an emulated CPU. Using the already existing Core i5-12600K, Igor adjusted the base clock and turbo clock to match the specs of the upcoming Core i5-12400. In addition to that, he disabled the E-cores to accurately recreate the unreleased processor. It’s possible that he also used other CPUs to recreate the i5-12400, as he mentions the Intel Core i9-12900K in his hardware lineup.

In addition to the processor, the system was running DDR4 memory, and it was based on the MSI MAG Z690 Edge motherboard. Interestingly enough, based on the testing, Igor’s Lab states that DDR4 memory was the more optimal option for this processor, so it didn’t use the new DDR5 RAM.

These tests certainly bode well for the Core i5-12400, but it’s important to remember that this is not just unreleased hardware: The benchmark was done on a simulated system based on C0 silicon. While Igor’s Lab was able to accurately recreate the new CPU, there are still differences in L3 cache sizes, and the chips themselves may also differ in some ways. We can expect to see up-to-date benchmarks when the CPU is officially released in January.

AMD Ryzen 9 7950X3D vs. Intel Core i9-13900K: only one choice for PC gamers
AMD's Ryzen 9 7950X3D inside of its packaging.

The AMD Ryzen 9 7950X3D and Intel Core i9-13900K are undoubtedly two of the best processors you can buy, but they aren't equal. We threw both of the CPUs on the test bench to answer the age-old question: is AMD or Intel better?

Based on our testing, the Ryzen 9 7950X3D wins this bout, mostly on the back of the excellent gaming performance AMD's 3D V-Cache technology brings. Intel's Core i9-13900K still holds up, particularly in productivity apps, but Team Red takes the win this time around.

Intel’s Core i9-13900KS hits 6GHz out of the box, but there’s a catch
Intel Core i9-13900K held between fingertips.

Intel has just launched the Core i9-13900KS, a CPU to end all CPUs -- at least in this generation. This is Intel's most powerful chip right now, fully poised to top the list of the best processors on the market.

This doesn't just mark yet another entry into Intel's impressive CPU arsenal. The Core i9-13900KS stands out as the first consumer processor to hit 6GHz out of the box without extra overclocking. To hit that peak, however, it's going to consume a whole lot of power.

Intel’s 24-core laptop CPU might outclass desktop i9 processors
A render of Intel's H-series mobile processors.

Intel is pushing laptop CPU core counts to places they've never been before. The company announced its 13th-gen Raptor Lake mobile processors at CES 2023, including the flagship Core i9-13980HX which includes a massive 24 cores that could top the list of the best Intel processors.

That sounds insane considering even AMD's desktop Ryzen 9 7950X only comes with 16 cores. But Intel's cores aren't all built equally. Like the previous generation, 13th-gen mobile Raptor Lake processors include a combination of performance (P) cores and efficient (E) cores. The most powerful chips in the range come with 24 cores, but they're split across eight P-cores and 16 E-cores.
