Back at its Architecture Day 2021 event, Intel announced that its upcoming Alder Lake processors will not only support next-gen DDR5 DRAM, but it'll also be compatible with the current DDR4 kits too. And a recent purported leak has suggested that the Alder Lake Integrated Memory Controller (IMC) will be capable enough to handle some hefty DDR5 overclocks too as the flagship Core i9-12900K is seen running an unreleased Gigabyte AORUS DDR5-6200 kit at 8008 MT/s.
And for those wondering how the performance of the 12th gen Intel processors will be on a DDR4 platform, there is some good news as the performance of the Core i7-12700K has leaked. The Alder Lake-S Core i7-12700K is rumored to be a 12-core, 20-thread part carrying an (8+4) configuration.
The benchmarks were dug up by renowned Twitter leakster APISAK from the PugetBench database. Later, it was collected and shared by Twitter user Dylan Patel alongside other competing processors from both Intel and AMD. Click on the image below to enlarge.
Interestingly the performance for the i7-12700K here seems pretty much on par with the leaked Core i9-12900K numbers recently as both the CPUs' overall score in After Effects is around ~1570. The i7 however is running on a DDR4 platform as noted earlier compared to the reported DDR5-4800 on the i9's and there isn't much of a difference. But then again, After Effects isn't really affected much by memory speeds so it's possible we will see more noticeable gains in other more memory speed-sensitive tests.
And we will probably know this and much more sooner rather than later as Intel's Gregory M Bryant says that the 12th Gen Alder Lake processors are "coming soon to PCs globally".
