> So they introduced a new socket/platform for supporting up to 64 cores, yet still restricted memory to 256GB UDIMMs, instead of switching over to LRDIMM and allowing up to 4TB of RAM. The only reason all desktops don't support RDIMMs in addition to UDIMMs is market segmentation. The Athlon XP supported both because they were really the same die with the same memory controller as the Athlon MP. They're playing the same stupid game as Intel now but it's nothing new with TR3. They've been doing it since the Athlon 64 or so. Though it's especially annoying because the "workstation" models (FX/TR) have higher clocks than Opteron/Epyc, so there is no way to combine the higher clocked processors with the higher memory capacity boards. > And the whole platform is dead the moment DDR5 shows up (2021?). That happens either way. You're regarding this as a whole new platform they had to design just for this, but it's more like a little tweak on the existing design with the unfortunate side effect of breaking compatibility. > Also, no single TRX40 board has more than 4 PCIe slots... There are boards with four real x16 slots, which is 64 lanes. The other 8 are needed for the on-board devices.
