AMD's AM5 platform is set to erupt onto the desktop in the fall, and not only can we expect X670 and B650 motherboards to arrive with the company's Zen 4 processors at that time, but also a brand new X670E (the 'E' stands for 'Extreme') chipset. This chipset will find its way into the biggest and baddest motherboards from AMD; delivering maximum overclockability, massive VRMs, and PCIe 5.0 all over.
To understand what X670E can deliver we have to first look at the AM5 socket. This is an entirely new design for AMD and one that will see the company ditch its pin-grid array (PGA) chips in favour of land-grid array (LGA) ones. The switch will see AMD more like Intel's existing lineup with the contact pins located on the motherboard—1,718 of them in AM5's case.
AMD's David McAfee says the change to LGA also helps «to drive more power and greater signal integrity for all of those high-speed IOs.»
That also means you'll have to be extremely careful not to jam your thumbs into your X670E, X670, or B650 motherboard in a few months' time.
A few other key points about AM5: AMD's designed the socket to deliver up to 170W natively, which should see a decent amount of headroom for overclocking without any extra juice, though it's likely some motherboard manufacturers will over-spec at least a handful of high-end models.
«The socket AM5 ecosystem also features an all-new SVI3 power infrastructure. This brings multiple advantages to the platform, such as support for additional power phases, for that higher power delivery into the motherboard, finegrain power control, and significantly faster voltage response capabilities,» McAfee says.
PCIe 5.0 has also made the cut, though the exact amount of PCIe slots/M.2 slots will differ between
