More cores, more cache, DDR5-5600 support but PCIe Gen 5 M.2 missing

Details of the 13th Gen Intel Raptor Lake Desktop CPU platform were leaked during a Presentation ‘NAS Workshop’ in Shenzhen, China. The slide gives us a good overview of the features one should expect from upcoming processors, but one crucial feature is also missing.

Intel Raptor Lake desktop processor platform details leaked: DDR5-5600 support confirmed but no word on PCIe Gen 5 M.2 support

On paper, the 13th Gen Intel Raptor Lake processors appear to be an optimized version of the 12th Gen Alder Lake processors. They will be based on the same ‘Intel 7’ 10nm ESF process node, use the same P-Core and E-Core design and will be supported on existing motherboards. But there’s a lot changing with Raptor Lake and we’re going to detail everything from official details to the rumors we know about Alder Lake so far and what you can expect from the next line of desktops. from Intel which will be opposed to the next Ryzen from AMD. Range of processors for desktop computers as well.

Expected Features of 13th Generation Intel Raptor Lake Desktop Processors:

  • Up to 24 cores and 32 threads
  • New Raptor Cove processor cores (Higher P-Core IPC)
  • Based on 10nm ESF ‘Intel 7’ process node
  • Supported on existing LGA 1700 motherboards
  • DDR5-5600 dual channel memory support
  • 20 PCIe Gen 5 lanes
  • Improved overclocking functions
  • 125W PL1 TDP (flagship references)

Intel is sticking with its LGA 1700 platform for at least one other line of processors and that’s Raptor Lake. Chipzilla has confirmed that Raptor Lake processors will be compatible with existing LGA 1700 motherboards based on the 600 series chipset. the 700 series which will come with higher I/O lanes. On top of that, the Raptor Lake chips will support DDR5-5600 speeds, which is a nice step up from the native DDR5-5200 speeds supported by Alder Lake. The processors will also continue to support DDR4-3200 on D4 series motherboards.

This provides a good upgrade path for users who are currently using a mainstream Core i3 or Core i5 CPU and want to upgrade to a high-end chip. They can simply replace their existing 12th Gen processor with a high-end Core i7 or Core i9 SKU which will increase the overall performance of their PC.

The 13th generation processor will also offer improved overclocking capabilities. Alder Lake is currently clocking up to 5.5GHz with the upcoming Core i9-12900KS SKU which is rated at a maximum rated power of 260W, the highest ever on the mainstream platform. On top of that, the Raptor Lake CPUs will also offer 16 PCIe Gen 5.0 lanes, 4 PCIe 4.0 lanes, and an x8 (Gen 4) interconnect for DMI. The PCH will carry additional PCI Gen 4.0 lanes in addition to increased USB 3.2 Gen 2×2 (20G) ports, PCIe 3.0 and SATA III connections.

There is also new AI M.2 module support which is supported by Raptor Lake processors, but the slide does not mention PCIe Gen 5 support for M.2 anywhere, which is a bit odd. Recently there have been rumors of Intel having Z790 motherboards with PCIe Gen 5, but given that AMD is moving to Gen 5 with their 600 series platform, Intel is very likely to offer the support for Gen 5 M.2 SSD on its newer motherboards, but those x16 Gen 5 CPU lanes are going to be split between dGPU and M.2 SSDs.
