AMD outs Ryzen 4000 PRO Lineup for Mobile Workstations: More Cores, Higher IPC and Longer Battery Life

AMD today announced the arrival of the Ryzen 4000 PRO series of mobile APUs. The Ryzen 4000 PRO series is built for productivity and business use cases, with an added focus on security. The new PRO series APUs include the Ryzen 7 PRO 4750U, the Ryzen 5 PRO 4650U, and the Ryzen 3 PRO 4450U.

All three of these parts have a 15W TDP, making them well suited to business laptops and ultrabooks. The Ryzen 7 PRO 4750U is the flagship and features 8 core and 16 threads, clocked up to 4.1 GHz, and 12 MB of L3 cache. The Ryzen 5 PRO 4650U features 6 cores and 12 threads, clocks up to 4 GHz, and features 11 MB of cache. The Ryzen 3 PRO 4450U, the entry-level offering in this lineup, features 4 cores and 8 threads at up to 3.7 GHz, and 6MB of cache. 

The new Ryzen 4000 PRO lineup directly succeeds Zen+ based AMD’s Ryzen 7 PRO 3700, Ryzen 5 PRO 4500U, and Ryzen 3 PRO 3300U, offering more cores and threads at every price point. AMD claims that the top-end Ryzen 7 PRO 4750U delivers 30% higher single-threaded performance and 130% greater multi-threaded performance, compared to preceding Picasso parts thanks to the use of 7nm Zen 2 cores.

AMD also claims up to 20 hours of battery life with the new chips, making all-day business use a possibility. Both HP and Lenovo will be offering Ryzen 7 PRO laptops shortly. These include the HP ProBook x360 435 G7, and the Lenovo ThinkPad T14 Gen 1, among others.
