Hardware reviewer and leaker Golden Pig Upgrade claims Intel has set two separate embargoes for the new Core Ultra 300 series. Intel has already confirmed that laptops featuring Core Ultra 300 will launch on January 27.
The leak says the first review embargo will lift for the Core Ultra X9 388H on January 26. One day later, on January 27, reviews for the remaining Panther Lake chips would follow.

The Core Ultra X9 388H is the flagship SKU, with higher clocks and the most capable iGPU configuration, Arc B390, also running at the highest clocks. Intel has not explained the split, and it is unclear how many laptops will ship with the 388H at launch.
January is also packed with other embargoes. Ryzen AI 400 laptops are set to launch on January 22. The month should end with Ryzen 7 9850X3D reviews and sales.
Upcoming Product Embargoes
January 22nd: Ryzen AI 400 laptop sales (China)
January 26th: Core Ultra X9 388H Laptop Reviews
January 27th: Other Core Ultra Laptop Reviews & Core Ultra 300 Laptops Sales
January 28th: AMD Ryzen 7 9850X3D Reviews
January 29th: AMD Ryzen 7 9850X3D Sales
Graphics aside, the X9 388H sits at the top of the lineup with 16 CPU cores, support for LPDDR5X-9600 memory, and a maximum power limit of up to 80W.
Based on what we saw at CES, these CPUs are expected to appear in higher-end systems such as the MSI Prestige 16 Flip AI+, Acer Swift 16 AI, GMKtec Evo-T2 mini PC, and the ASUS ROG Zephyrus G14, which was reportedly canceled shortly before CES.
