Intel will unveil its 13th Gen Raptor Lake CPUs in the next few months, but rumors are already talking about 14th Gen Meteor Lake and 15th Gen Arrow Lake CPUs, which will be available in new desktop models using the LGA 2551 socket Launched on the CPU platform.
The latest details come from MILD, which says that Intel expects to launch its 14th-generation Meteor Lake CPUs in 2023 and 15th-generation Arrow Lake CPUs in 2024. Both products are now confirmed by Intel themselves. The key detail in the latest footage is that both series will use a brand new slot called the LGA 2551.
The Intel LGA 2551 socket will replace the LGA 1700/1800 sockets currently supporting 12th Gen Alder Lake and 13th Gen Raptor Lake CPUs. Intel is known to transition to newer sockets every 2 generations. The LGA 1200 socket also supports 10th Gen Comet Lake and 11th Gen Rocket Lake CPUs. While the sockets remain the same, each CPU gets a ton of improvements to I/O that come with newer chips. AMD and Intel use the same philosophy as we’ve seen multiple chipset modifications and updates on the same socket.
According to the detailed information, the exact dimensions of the Intel LGA 2551 socket for Meteor Lake and Arrow Lake CPUs are 38mm x 46mm, which is only slightly larger than the existing LGA 1700/1800 socket, which means that the socket is in Doesn’t take up a lot of space on mainstream platforms. This would make the Intel LGA 2551 socket the largest for mainstream desktops, with 751 more pins than Intel’s current mainstream socket and 833 more pins than AMD’s AM5 socket (LGA 1718). So let’s take a quick look at the Meteor Lake and Arrow Lake CPU families.
The 14th Gen Meteor Lake CPUs will change gamers as they will take on a whole new approach to tiled architecture. Using the Intel4 process, the new CPU will increase the performance per W by 20% through EUV technology, and is planned to be Tape out (manufacturing ready) before 2H 2022. The first Meteor Lake CPUs are scheduled to launch by 1H 2023 and are expected to be available later in the same year. Rumor has it that the desktop version will hit shelves in the second half of 2023.
According to Intel, the 14th Gen Meteor Lake CPUs will feature a brand new tiled architecture, which basically means the company has decided to go all-in with small chips. There are 4 main tiles on Meteor Lake CPUs. There are IO Tile, SOC Tile, GFX Tile and Compute Tile. Compute Tile includes CPU Tile and GFX Tile. The CPU Tile will use a new hybrid core design consisting of Redwood Cove P-Cores and Crestmont E-Cores to deliver higher performance throughput at lower power consumption, while the GFX tile will be unlike anything we’ve seen before. The TDP of CPUs will range from 5W to 125W, from ultra-low TDP mobile to high-end desktops.
As Raja Koduri said, Meteor Lake CPUs will use tiled Arc display-driven GPUs, which will make it an all-new wafer-level display. It is neither an iGPU nor a dGPU and is currently considered a tGPU (Tiled GPU/Next-Gen Graphics Engine). The Meteor Lake CPUs will feature a new Xe-HPG display architecture that will boost performance at the same level of energy efficiency as existing integrated GPUs. This will also enhance support for DirectX 12 Ultimate and XeSS.
The successor to Meteor Lake is Arrow Lake, and the 15th generation brings a lot of changes. While it will be socket compatible with Meteor Lake, the Redwood Cove and Crestmont cores will be upgraded to the brand new Lion Cove and Skymont cores. These are expected to bring major advantages as the new model (8 P-Cores + 32 E-Cores) has an increased core count.
Previous leaks have confirmed the mainstream of the desktop K-series. Performance is said to be on par with AMD and Apple processors, which means these processors will offer double-digit gains. No word yet on the GFX Tile, but it should have an updated architecture or an added Xe core. The I/O tiles will be fused with the Neural Engine (VPU), similar to the Neural Engine on Meteor Lake, which will use low-power Atom cores.
Surprisingly, Intel will skip its Intel 4 process and go straight to 20A for Arrow Lake CPUs. One thing about the Meteor Lake and Arrow Lake wafers is that they will keep their N3 (TSMC) process for additional core IP, presumably Arc GPU cores. The Intel 20A process will leverage next-generation RibbonFET and PowerVia technologies to deliver a 15% performance-per-watt improvement, with plans to execute the first IP test wafers in the fab in the second half of 2022.
In addition, Arrow Lake will also use a four-chip design, the same as Meteor Lake, but with more cores and IO functions. The 20A process itself will improve performance per watt by 15% and bring RibbonFET and PowerVia technology to the desktop.
