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.

Intel Core i9-13900K vs. Core i9-12900K: Is it worth the upgrade?
Intel Core i9-12900K in a motherboard.

Intel Raptor Lake is finally here, and although there's a handful of CPUs in this first wave of 13th-generation CPUs, it's hard not to focus on the flagship, the Intel Core i9-13900K. Equipped with a seemingly endless number of cores, capable of hitting those ultra-high clock speeds, and socket-compatible with Alder Lake, it checks most of the boxes as far as the top-shelf CPUs are concerned.

But the 13900K is mostly just a refinement of the 12900K with extra cores. Is getting a Core i9-13900K worth the splurge, or should you keep things more budget-friendly with a 12th-gen CPU? Below, we'll compare the two Intel flagships and help you choose a winner.

AMD Ryzen 9 7950X vs. Intel Core i9-12900K: Two flagships face off
A hand holding the Ryzen 9 7950X in front of a green light.

When the Intel Core i9-12900K came out in late 2021, it was Intel's first true flagship CPU since its 2018 Core i9-9900K. It actually beat AMD's flagship Ryzen 9 5950X in both single- and multi-threaded performance, and the 12900K remains the fastest mainstream desktop CPU to this day and one of the best CPUs in general.

But AMD now has its Ryzen 9 7950X. It blows past AMD's previous-generation offerings, there's no doubt about that. Even against Intel's most powerful CPU to date, however, AMD's latest processor shows a big jump in performance.

Ryzen 7 7700X vs. Intel Core i7-12700K
The Ryzen 7 7700X CPU.

Looking for a CPU upgrade for your gaming machine? We’ve got some good news: AMD's Ryzen 7000 Zen 4 CPUs are set to deliver significant boosts in performance compared to the previous generation and long-awaited support upgrades for the latest connections.

The Ryzen 7 7700X chip, in particular, looks like an excellent combination between a performance upgrade and affordability. But that also sets it against the similarly priced Intel Core i7 12700K -- a chip from the 12th-generation Alder Lake series Intel released in late 2021. Just how do these processors stack up, especially for gamers? Let’s take a look at what we know.
