Theo đó có 4 phiên bản gồm Core i5-8250U/8350U và Core i7-8550U/8650U và đều 4 nhân 8 luồng. Thuộc dòng U nên TDP của các phiên bản CPU này vẫn ở mức 15 W. Điều đáng chú ý là xung nhịp, mặc dù xung cơ bản thấp nhưng xung Turbo Boost vẫn ngang ngửa với các phiên bản thế hệ Kaby Lake. Chẳng hạn như với phiên bản Core i5-8250U, xung cơ bản 1,6 GHz và Turbo Boost được 3,4 GHz. So với Core i5-7260U 2 nhân 4 luồng thì xung cơ bản đã là 2,2 GHz nhưng vẫn cùng mức Turbo Boost 3,4 GHz. Ngoài ra, bộ đệm L3 còn được tăng thêm rất đáng kể, i5 và i7 dòng U thế hệ Kaby Lake vốn chỉ có 3 MB và 4 MB bộ đệm L3 thì giờ tăng gấp đôi thành 6 MB và 8 MB. Show
 Chưa hết, thông tin trên xuất hiện trong bảng giá được Intel gởi đến các OEM. Mức giá đề nghị cho 4 phiên bản này đều tương đương với 4 phiên bản mà nó thay thế thuộc thế hệ Kaby Lake, chẳng hạn như Core i5-8250U/8350U đều có giá $297 trong khi Core i5-7260U/7360U có giá $304, tương tự Core i7-8550U/8560U đều có giá $409, vẫn rẻ hơn so với Core i7-7560U/7660U là $415. Điều này có nghĩa giá của những chiếc laptop chạy Core i5/i7 dòng U thế hệ Coffee Lake sẽ tương đương với thế hệ Kaby Lake hoặc có thể rẻ hơn. Trang LaptopMedia cũng đã có được một mẫu máy chạy Core i7-8550U và họ đã tiến hành benchmark hiệu năng. Sơ lược Core i7-8550U có 4 nhân 8 luồng, xung nhịp 1,8 > 4 GHz, 8 MB Cache L3. Họ đã so sánh kết quả này với 3 phiên bản CPU khác gồm Intel Core i7-7500U (Kaby Lake, 2/4, 2,7 > 3,5 GHz, 4 MB Cache L3) và Core i5-6300HQ (Skylake, 4/4, 2,3 > 3,2 GHz, 6 MB Cache L3) và Core i5-7300HQ (Kaby Lake, 4/4, 2,5 > 3,5 GHz, 6 MB Cache L3). Đây đều là những dòng CPU phổ biến trên laptop và kết quả là: Hiệu năng của Core i7-8550U có thể nói là ngang ngửa với Core i5 dòng HQ trên laptop. Theo nhận định của LaptopMedia thì dòng CPU mới này sẽ thay đổi quan niệm của chúng ta về việc một chiếc laptop chạy CPU tiết kiệm điện thì không thể chơi game tốt hay phải đánh đổi giữa hiệu năng và mức tiêu thụ điện năng. Không chỉ chơi game, dòng CPU này có thể đáp ứng được các tác vụ nặng, chẳng hạn như Photoshop. LaptopMedia cũng đã test Adobe Photoshop Action và đo thời gian hoàn thành tác vụ. Core i7-8550U mất 10,5 giây, ngang ngửa với Core i7-7700HQ vốn thường thấy trên những dòng laptop chơi game cao cấp. P/S: Mình được một anh bên Acer gởi cho hình chụp cấu hình của một chiếc laptop chạy Core i5-8250U, 8 GB RAM. Được biết máy đã về Việt Nam, hy vọng sẽ sớm mượn được để đánh giá nhanh cho anh em.
