Announced at IFA 2019, Lenovo's Yoga C640 is the entry level to the company's Yoga lineup. The model that the company sent me costs $599, which isn't bad for a 13.3-inch convertible PC with pen support.
That price gets you a Full HD display, 8GB RAM, and a 128GB SSD. The CPU that it comes with is an Intel Core i3-10110U, which is from the firm's Comet Lake lineup. The 14nm chip is still dual-core with four threads, and it uses UHD Graphics. If you want something a little better, Lenovo.com actually has one with a Core i5-10210U and a 256GB SSD.
Another big change, however, is that it has an Intel processor at all. 2018's Yoga C630 WOS actually had a Qualcomm Snapdragon 850 chipset. Aside from being a Windows on ARM PC, there were no USB Type-A ports, and it charged via USB Type-C. The C640 is different though, packing two USB 3.1 Gen 1 Type-A ports, and while it has a USB 3.1 Gen 1 Type-C port, it doesn't support charging.
