Today sees AMD unveil its Ryzen PRO 4000 chips, the world’s first x86 7nm commercial notebook processors aimed at business users who demand security-centric features and enterprise-grade reliability.
AMD is pitching its new Ryzen PRO 4000 processors as “the new standard for modern business PCs” offering what is claimed to be the best performing processor, the most advanced technology, and, perhaps more significant for business, the most modern security.
Three U-series mobile chips have been announced.
AMD Ryzen 7 PRO 4750U
- 8 cores/16 threads
- Up to 4.1GHz/1.7GHz
- 12MB cache
- 7 graphics cores
- 1600MHz graphics frequency
- 15W TDP.
AMD Ryzen 5 PRO 4650U
- 6 cores/12 threads
- Up to 4.0GHz/2.1GHz
- 11MB cache
- 6 graphics cores
- 1500MHz graphics frequency
- 15W TDP.
AMD Ryzen 3 PRO 4550U
- 4 cores/8 threads
- Up to 3.7GHz/2.5GHz
- 6MB cache
- 5 graphics cores
- 1400MHz graphics frequency
- 15W TDP.
All these chips are based on AMD’s 7-nanometer Zen 2 architecture are “Power Optimized” for work from home, in the office, or on the go.
These chips offer a significant upgrade over the AMD Ryzen 7 PRO 3000 line, which topped out at 4 cores/8 threads and 6MB cache.
Pitching the Ryzen 7 Pro 4750U against its predecessor, the Ryzen 7 PRO 3700U, single thread, multi thread, and graphics performance is up 29 percent, 132 percent, and 13 percent respectively.
In real-world benchmarks using the likes of Microsoft Word, PowerPoint, Edge, and Excel, performance compared to the previous-generation silicon is up 19 percent, 27 percent, 39 percent, and 77 percent respectively.
