Intel 12th Gen Alder Lake CPUs will replace LGA 1200 for LGA 1700 socket

Intel Alder Lake CPUs which is expected to be out by 2020. Interestingly,  it will be using a different socket- the LGA 1700. The information is sourced from a Taiwanese based company ‘Lit-Tech‘. The organization is responsible for manufacturing voltage regulator tools. Most likely, it was creating tools for Intel Asia Pacific division. It identified some Alder Lake-S SKUs.

About the LGA 1200 sockets…

The LGA 1200 would just end up housing two architectures, the 10th gen Comet Lake and its successor Rocket Lake. Both will work on the Intel B460 and the Z490 chipset motherboards, with the 11th generation coming later this year with PCIe 4.0 support. The Z490 is said to have PCIe 4.0 but will work only with Rocket Lake CPUs due to the sub-components on these motherboards.

It is assumed that the 500 series chipsets accompanying the Rocket Lake lineup will have a full PCIe 4.0 native support. At this point, Intel is trying to catch up with AMD by releasing 10th generation now and 11th generation by end of this year. By 2022, the new chipset and CPUs will use the new LGA socket.

What do we know about Alder Lake?

What’s interesting about Intel Alder Lake CPUs are made on 10nm++ process. 12th generation platform is also expected to have PCIe 5.0 support and DDR5. Unlike the square-shaped mainstream CPUs by Intel, these are more rectangular shaped. The LGA 1200 CPUs are 37.5mm x 37.5 mm. It is also the reason why it has the same mounting holes as the LGA 115x CPU socket. Because of this, the lifespan of the LGA 115x aftermarket coolers has expanded. The Alder Lake’s LGA 1700 socket is rectangular shaped, measuring at 45mm x 37.5mm. It is safe to say that LGA 1700 won’t be able to retain aftermarket CPU coolers made for the LGA 115x and hence the LGA 1200 CPUs.

But this can be a good sign. The requirement for having a broader mainstream CPU could imply a significantly different architecture and even better power delivery system. This socket is expected to support three CPU generations.

The reasoning behind this jump

The changes between the LGA 1151 to LGA 1200 is minuscule Though Intel did enable overclocking for its mid-end B460 chipset, which was traditionally disabled. Intel must have felt a blow in its mid-range offerings against AMD counterparts. One of AMD B series offerings is the overclocking function. Intel has a lot of catching up to do against AMD whose B550 with PCIe 4.0 is expected to be out soon. Clearly it needed to do something radical. Alder Lake is probably Intel’s solution.

Some of Intel Alder Lake’s variant will use an ARM’s big.LITTLE architecture with 8+8+1 core. This means there will be eight high powered cores, eight low-powered cores and one on-chip graphics core.
