AMD Brings Ryzen 4000 Series Mobile Processors: CES 2020

Along with the world’s most powerful desktop processor, AMD is also bringing its most powerful 7nm mobile processors in the market. At CES 2020, the company announced AMD Ryzen 4000 series mobile laptop processors as an update to the 3000 series.

Now with Zen 2 7nm architecture, the new AMD 4000 series laptop processors offer more speed and performance with up to 8 cores. Following the same naming scheme as Intel, these CPUs come in two flavors, “H” and “U”. Processors with “H” suffix are rated at 45W TDP and features high performance for gaming and content creation. Whereas the “U” series processors are more energy efficient with a TDP of 15W.

Except for AMD Ryzen 3 4300U, all of the 4000 15W processors can reach boost clocks up to 4GHz or more. However, the base clocks of these CPUs are lower than the 45W processors. Some of the processors such as 4300U, 4500U, and 4700U sacrifice two threads per core in order to gain reasonable base clocks.

LPDDRX4 Support

All of the CPUs come with support for DDR4 at 3200MHz speeds. What’s more exciting is the introduction of LPDDR4X RAM that offers memory speeds of 4266MHz. All of the 4000 series Ryzen mobile processors will support this new memory with a capacity of up to 64GB.

More Performance Per Watt

Due to the new architecture, the new AMD 4000 series laptop processors boast up to 2x performance per watt improvement. As a result, with minimal power, the laptop can run for even longer periods at even better performance.

In the presentation, AMD also showed the performance of its new processor 4800U against the closest Intel Competitor. Compared to the Intel’s 10th gen Core-i7 1065G7 CPU, Ryzen 7 4800U is up to 4% faster in a single thread and almost 90% faster in multi-thread performance. Additionally, it also defeats the i7-1065G7 by 28% in terms of graphics performance.

Instead of PCIe 4.0, all of these Ryzen 4000 series mobile laptop processors support the older PCIe 3.0 interface.


UPDATE: AMD introduced 2 more Ryzen 4000 series mobile processors to the lineup.
