AMD has been very proud about keeping to its CPU roadmap and if you’ve been following it closely, you’ll know that its 5nm Zen 4 architecture is very nearly upon us. On that note, new and interesting rumours surrounding the upcoming CPU lineup have emerged.
According to a tweet by a well-known leaker, ExecutableFix (@ExecuFix), AMD could be planning on shifting from using a Pin Grid Array (PGA) design to the Land Grid Array (LGA) format for its upcoming AM5 socket. On top of that, the socket size could be an LGA1718, which is obviously bigger than the current PGA1331 socket that AMD has been using in all Ryzen CPUs, since the launch of the very first processor back in 2017.
In addition, ExecutableFix also tweeted that the new chipset will, like Intel’s own upcoming Alder Lake-S, support dual-channel DDR5 memory, but seemingly sticks to the current PCIe 4.0 interface, which is a little surprising. Moreover, it seems that AMD will continue its current naming convention with the 600 series moniker.
– Dual-channel DDR5
– PCI-e 4.0
– 600 series chipset

To be fair, this wouldn’t be the first time AMD has opted to use LGA over PGA. As many of you know, the company’s Threadripper series CPU, TR40 and TRX40, are based on the LGA format. As for the alleged decision to stick to PCIe 4.0 instead of PCIe 5.0, the interface is still relatively new, having only launched less than a couple of years ago.
On top of that, it can be argued that platforms today are still not making full use of the interface. For that matter, Intel only just began supporting PCIe 4.0, so if anything, having PCIe 5.0 support on Alder Lake-S is simply bragging rights.
