Intel expects to show the 14th generation meteor lake-p CPU during the IEEE VLSI technology and circuit seminar, but it seems that the kernel photos and details have been leaked a few days before the event The PowerPoint slides planned to be displayed in this event have been leaked by twitter user @phobiaphilia, but he then deleted these pictures. Fortunately, computerbase managed to obtain these slides
These slides discuss the Intel next generation process node, called Intel 4, which is essentially a renamed 7Nm technology. The 14th generation meteor Lake CPU will utilize the "Intel 4" process node, and provide twice the HPL (high performance Library) scaling, EUV for simplifying the process, ISO 20% higher frequency than Intel 7 nodes (by alder lake and Raptor Lake CPU), and provide compatibility with advanced packaging technologies such as emib and foveros.
In general, the functions of the "Intel 4" process node include:
● 2x high performance library area scaling
● extensive use of EUV to simplify process
● 20% higher frequency than Intel 7 (for alder lake and Raptor Lake)
● technology compatible with advanced packaging options such as emib and foveros
Intel also talked about the power frequency scaling of its "Intel 4" nodes. Although it is reported that the 14th generation meteor Lake CPU will have clock regression compared with the chips based on "Intel 7", the slide shows that the frequency jump will be higher than "Intel 7" under the same power. It may not be reflected in the entire 7Nm product family, but this is at least Intel's goal. Therefore, in terms of clock, we can expect to increase the clock rate by 20% at the same power level.
In addition, the slide details the 2x HPL extension of the Intel 4 node for the 14th generation meteor Lake CPU. The next generation CPU will have:
● contact polysilicon spacing (nm):54/60 and 50 (0.93x/0.83x scaling)
● fin spacing (nm):34 to 30 (0.88x scaling)
● M0 spacing (nm):40 to 30 (0.75x scaling)
● HP library height (nm):408 and 240 (0.59x scaling)
● library Height x CCP (Nm2):24.4k and 12K (0.49x scaling)
