Later yesterday, Intel's ARK database formally announced the first 10nm processor, i3-8121U main specifications information.
The i3-8121U uses the Cannon Lake architecture, which belongs to the 8-generation Core family, a dual-core, four-thread design with a base frequency of 2.2 GHz, thermal design power consumption of 15 W, and nuclear information is unknown.

The main improvement is that First, LPDDR4/X-2400 memory is supported for the first time. The bandwidth is increased from 34.1GB/s to 41.6GB/s. Second, the number of PCIe channels is expanded from 12 to 16. Third, the AVX-512 instruction set is added..
In fact, when I first appeared in the ARK yesterday, the i3-8121U only supported AVX2 (AVX-256). It instantly regretted many people. However, Twitter user InstLatX64 uses the CPUID dump command to find that the former actually supports AVX512 (F, CD, BW, DQ, VL, IFMA, VBMI), and even SHA (accelerated cryptographic operations).
This AVX is called the advanced vector extended instruction set and supports 512-bit integer arithmetic. It belongs to the third generation instruction set of AVX. Of course, the birth of AVX still has a history of contention with AMD. AMD's SSE5 failure eventually had to support AVX.
It may be that the composition of 'squeezing toothpaste' is quite obvious, Intel just released such a film, and no press release was even published.
The specific performance data comes from a vendor who sells the IdeaPad 330 notebook, claiming a 25% increase over the i3-6006U.
However, in fact, the information-integrated i3-8121U also appeared in the SiSoft Sandra database. The total multimedia performance score is 142.13 Mpix/s, which is basically the mean value downstream of the average.
