On February 23 (US Pacific time), Intel announced that among the 12th generation Core processors for mobile (development code name: Alder Lake), the basic power consumption (PBP, * 1) is 24W "P processor" and 15W or 9W announced that it is expected that PCs equipped with the "U processor" will be released sequentially from March. More than 200 new models from Acer, ASUSTek, Dell Technologies, Fujitsu Client Computing, HP, Lenovo, LG, MSI, NEC Personal Computers, Samsung Electronics, etc. In this article, we will explain the details of the P processor / U processor and the 3rd generation "Intel Evo platform" based on the contents of the briefing held by Intel for the press. Some of the content that has already been announced is included, but I hope it will be helpful. (*1) Processor Base Power: Power consumption equivalent to the conventional "TDP (Thermal Design Power)" and "PL1 (Power Limit 1)" ● Overview of CPU specifications 　The 12th generation Core processor emphasizes processing performance The core (P core)" and the "efficiency core (E core)" that emphasizes processing efficiency (power saving) are mixed. Mobile products are provided as "SoC (System-On-a-Chip)" that integrates a chipset (south bridge) in addition to a CPU and GPU. The package (chip mounting size) is "BGA Type 3 (50 x 25 x 1.3 mm)" for the P processor and PBP 15 W U processor, and "BGA Type 4 HDI (28.5 x 19 x 1.1 mm)" for the PBP 9 W U processor. becomes. Processor functionality varies from package to package. P processor/U processor (15W) The main specifications of the 15W models of the P processor and U processor, which use the BGA Type3 package, are similar to the high-end "H processor" (PBP is 45W) that was introduced earlier. However, the PCI Express 4.0 bus for the external (independent) GPU is reduced.・CPU core (P core supports hyper-threading) ・P processor has a maximum of 12 cores and 24 threads (6 P cores + 8 E cores) ・U processor has a maximum of 10 cores and 12 threads (2 P cores + 8 E cores) GPU Core (Xe-LP architecture, maximum operating clock varies by model) ・Core i7 processor has 96 EUs (execution units) ・Core i5 processor has 80 EUs ・Core i3 processor has 64 EUs ・Pentium/Celeron Processor EU has 48 units Main memory (maximum 2 channels) Supports DDR5-4800, DDR4-3200, LPDDR5-5200, LPDDR4x-4267 standards PCI Express/Serial ATA PCI Express 4.0 bus: total 8 lanes (storage device) ・PCI Express 3.0 bus: 12 lanes in total ・Serial ATA 3.0 port: 2 ports Thunderbolt/USB ・Thunderbolt 4 (USB4) port x 4 ・USB 3.1 port x 4 ・USB 2.0 port x 10 video output ・eDP (Embedded DisplayPort) 1.4b (HBR3 compatible), MIPI Display Serial Interface (DSI) 2.0, HDMI 2.0b Other ports/functions, Wi-Fi 6E (IEEE 802.11ax) standard wireless LAN (*2), 1000BASE-T standard Wired LAN, ISH (Integrated Sensor Hub), SPI (Serial Peripheral Interface) / eSPI (Enhanced SPI) (*2) Wi-Fi 6E is available only in some countries/regions. Can be used as "Wi-Fi 6" without using the 6GHz band in countries/regions where it is not available U processor (9W)　U processor 9W model is 15W of P processor and U processor to reduce mounting area and power consumption Some features have been reduced from the model. The main memory was also made to support only the low power standard.・CPU core (P core supports hyperthreading) ・Up to 10 cores 12 threads (2 P cores + 8 E cores) GPU core (Xe-LP architecture, maximum operating clock varies depending on model) ・Core i7 processor EU 96 EUs for Core i5 processors 80 EUs for Core i3 processors 64 EUs for Pentium/Celeron processors 48 EUs Main memory (up to 2 channels) Supports LPDDR5-5200 and LPDDR4x-4267 standards PCI Express/PCI Express 4.0 bus: total 4 lanes (for storage devices)/PCI Express 3.0 bus: total 10 lanes Thunderbolt/USB/Thunderbolt 4 (USB4) port x 2/USB 3.1 port x 4/USB 2.0 port x 6 video Output ・eDP 1.4b (HBR3 compatible) ・MIPI Display Serial Interface 2.0 ・HDMI 2.0b Other ports/functions ・Wi-Fi 6E standard wireless LAN ・1000BASE-T standard wired LAN ・ISH ・SPI/eSPI P processor "Enthusiast level" performance The PBP and turbo power (TP: maximum power consumption) of the P processor and U processor are set as follows. · P processor · PBP: 24W · TP: 64WU processor (15W model) · PBP: 15W · TP: 55WU processor (9W model) · PBP: 9W · TP: 29W　The name of the power mode is the predecessor (development code name: Tiger Lake ), but it should be understood that PBP corresponds to PL1 and TP to PL2, as mentioned in the previous note. However, since the maximum power consumption of the CPU in each PC is set within the range of "PBP or more and TP or less", it is the same as the predecessor that even the same CPU can have some performance difference depending on the manufacturer (or model). According to Intel, the Core i7-1265U (2 P cores + 8 E cores), which is the highest U processor with a PBP of 15 W, is the Core i7-1195G7 (2.
