The AM4 socket, which AMD has been using in mainstream processors for five years, is slowly becoming a successor. Leaked executable It revealed information about the first batch of motherboards and processors that should arrive next year.
The new platform will now be supported DDR5 It maintains two-channel access. Compared to DDR4, it will reach twice the frequency and four times the capacity.
The AM5 will initially only support interfaces PCI Express 4.0, Twice as fast as PCIe 5.0 to be the domain of Genoa server chips. However, an upgrade is likely to occur during the life of this platform. After all, AM4 also started with PCIe 3.0 and later published the fourth version of AMD Bus.
For graphics cards, PCIe 4.0 shouldn’t act as a brake, but four-line SSDs have already reached theoretical throughput limits. Intel will deploy PCIe 5.0 on the next generation of processors (Alder Lake).
ExecutableFix also revealed that the first chipset for the AM5 will be the 600 series And that processors retain physical Dimensions 40 x 40 mm As a pioneer. However, the processor connection changes from PGA (Peripheral Network Array) to LGA (Ground Grid Set) and the number of pins increases from 1331 to 1718.
With LGA, there are only contact pads on the processor and pins (bent) on the board. This has the advantage that the processor, which can be several times more expensive than the board, is not easily damaged. On the other hand, classic PGA vertical nails are relatively easy to straighten, while LGA oblique nails require more precision when repairing.
Intel LGA has been in mainstream since 2004 (LGA-775 / Socket T), and until now AMD has only used it on HPC and server processors like Opteron, Threadripper or Epyc.
