Alder Lake processors will support DDR5 memory

Extensive information on the Rocket Lake and Alder Lake processors disclosed, including the early TDPs.

Intel’s 10th generation desktop processors, Comet Lake-S are not out yet, but we still have information on the sequel, namely Rocket Lake and Alder Lake. We start with the most distant chips, Alder Lake, engraved in 10 nm if we rely on Intel’s roadmap. These will take place on an LGA1700 socket and will manage DDR5 memory.

This is what emerges from a report published by PTT, which also provides a wealth of data on TDPs for Rocket Lake chips, reported below. As for DDR5 memory, we’ve heard a lot about it in recent weeks, Cadence qualifying squarely 2020 of the year of DDR5. On the SK Hynix side, the company offered a detailed comparison between DDR5 and DDR4 memory.

AMD: support for DDR5 memory and PCIe 5.0 in 2022?

TDPs for Rocket Lake-S chips

We continue with the Rocket Lake-S processors, engraved in 14 nm. Also according to the PTT report, these funds will exploit the LGA1200 socket of the Comet Lake-S. For the TDP, they will be 95W for the 8 cores and 80W or 65W for the 6 and 4 core models.

More specifically, processors with a TDP of 95W (PL1) will have a PL2 power level of 173W and PL4 of 251W. Their value Tau, the variable which determines the time given to a chip outside of its PL1 stage, will be 56 seconds. For processors with a TDP of 80W, the PL2 power level will be 146W, the PL3 of 191W and the PL4 of 251W. Finally, for processors with a TDP of 65W, the PL2 will reach 128W, the PL3 177W and the PL4 251W. In the latter two cases, the Tau value will be 28 seconds.

Eight hearts maximum for Rocket Lake?

Reading the data above, some of you should be surprised by the mention of armed chips with a maximum of eight cores, while in the Comet Lake-S family, the Core i9 goes up to ten cores. No mistake, we just suspect that for its Rocket Lake-S processors, Intel is limited to eight cores. The idea would be to offer chips with high frequencies and CPIs to essentially target the video game market.

You will agree, this is a rather surprising choice, at a time when certain titles are proving more and more greedy in hearts, in particular GRID 2019 and Detroit: Become Human, and with next-generation consoles with eight cores looming on the horizon. Especially since on the AMD side, the standard bearer of the Ryzen 4000 would carry 32 cores and 64 threads… Anyway, we’ll see if the future proves Intel right. Furthermore, since the end of March, we also know that Rocket Lake-S will be synonymous with PCIe 4.0.
