Before the Raptor Lake (RPL) 13th generation Core was released, news of the Meteor Lake (MTL) 14th generation Core has been constant. It will be upgraded to the new Intel 4 process (the original 7nm), and for the first time, multiple small chip designs with separate CPU cores, GPU cores, and IO cores. Today, Igor’sLAB published the architecture diagram of the 14th generation Core Mobile, including the three series of H, P and U.
Different small chips are very obvious
The 12th and 13th generation Cores are hybrid architecture designs, commonly known as the large core P-core/performance core, plus the small core E core/efficiency core, while the 14th generation Core will add a new “small core” called LP E core, or low-power E core.
However, this low-power E core is separated from the P and E cores, not integrated in the computing chip, but still in the IO chip, so its main role should not be to provide computing power, but to manage the scheduling in standby, hibernation and other low-power states, so that the P and E cores can be completely shut down.
The 14th generation Core H and P series are up to 14 cores, while the U series is up to 12 cores, but this labeling does not seem to include low-power E cores, but 6P+8E, 6P+6E, no clear statement here, and the three-level cache is increased to a maximum of 24MB.
GPU core display, architecture from the current Xe LP upgrade to Xe LPG, still low-power, although it is not clear from Alchemist or the next generation Battlemage, but necessarily stronger graphics performance, the maximum number of execution units from 96 to 128, and the addition of expanded game mode, four-way video decoding mode.
Video output is a pleasant surprise, after the debut of the Arc A series graphics cards DP 2.0, and then upgraded to DP 2.1, also supports HDMI 2.1, eDP 1.4b, HBR3.
The memory supports DDR5-5600, LPDDR5/LPDDR5X-7467, with a maximum capacity of 96GB and 64GB respectively.
For expansion, PCIe 5.0 x8 is allocated to discrete graphics cards, which is of course limited to the H series, three PCIe 4.0 x4 is allocated to SSDs, and twelve PCIe 4.0 is allocated to various peripherals.
Up to four Thunderbolt 4 interfaces are compatible with PCIe 3.0, DP 1.4a, USB4, and USB 3.x at the same time.
Independent USB ports up to 3 USB 3.x, 10 USB 2.0.
The package is still 50×25×1.3mm BGA Type3, and will also integrate IPU 6 image enhancement processing unit, VPU/GNA 3.0 AI acceleration unit.
The 14th generation Core will be released in the second half of 2023.
