Rumour: AMD AM4 Socket to be as Big as FM2+, Summit Ridge to Natively Support DDR4 2400/2933 MHz
Yesterday, we reported that AMD AM4 socket will use μOPGA to increase pin count to 1,331 – around 33 per cent increase over the 950 pins used in previous AM and FM sockets – and support up to 140W chips.
Now according to a new leak, it has been revealed that the AM4 socket will be square and 40mm in length which is almost as large as the FM2+ socket.
As suggested earlier, although AMD is using more number of pins in the AMD AM4 socket, enlarging the current design is entirely out of question. To tackle the issue, the company has used the μOPGA instead of normal OPGA that essentially reduces the pin diameter, allowing for more pins to be fitted in the pretty much same space.
Aside from this, the leak also states that the memory controller on some of the earlier AM4 chips like AMD Summit Ridge will support DDR4 2,400MHz and DDR4 2,933MHz when overclocked.
Moreover, in order to save some money, AMD has used a standard IMC designed by Synopsys and due to low bandwidth DDR4, users can probably expect to see Zen APUs with HBM on Package.
Set to replace AM3+ which houses the FX line, AMD AM4 motherboards are scheduled to release sometime during the second quarter of this year!
