AMD announces Ryzen 4000 mobile series
AMD today introduces AMD Ryzen 4000 Mobile series featuring H-(high power) and U-(low power) series. The former feature two SKUs right now and both are 45W. They feature clocks up to 4.2 GHz and up to 8 cores (4800H).
The U-Series are all 15W and feature between 8 and 5 graphics cores. The series is divided into SMT-enabled and SMT- disabled parts, for instance, the Ryzen 7 4800U has 8 cores and 16-threads while the Ryzen 7 4700U has only 8 threads enabled.
AMD claims that Ryzen 4000 mobile series is up to 2x more power efficient per watt compared to Ryzen 3000 mobile series. They also feature LPDDR4x support.
With Renoir, AMD is also introducing a ‘smarter platform control’ known as SmartShift. This is basically the same technology (as a principle) as NVIDIA Optimus (to divert power between integrated and discrete GPUs).
