CES 2020: AMD Announces Zen 2 Ryzen 4000 Mobile Processors
Up to 8 cores and 16 threads in a thin and light form factor
As expected, AMD used its CES keynote Monday afternoon to announce updates to its Ryzen mobile lineup, including what AMD CEO Dr. Lisa Su called “the best laptop processor ever.”
The new Zen 2-based Ryzen 4000-series mobile processors will offer up to 8 cores and 16 threads in both the H (45W) and U (15W) device categories, providing a gen-over-gen increase that is “above the industry’s historical curve.” At these base TDPs and performance levels, the 7nm Ryzen 4000-series mobile lineup will target Intel’s 14nm Comet Lake and 10nm Ice Lake mobile parts.
As for integrated graphics, the new Ryzen 4000 mobile processors are still using Vega-based graphics, but with additional optimizations to offer up to 59 percent better performance. That’s enough to take back the performance crown from Intel’s Ice Lake Gen11 graphics, according to AMD.
In terms of battery life, which has been an area where AMD has trailed Intel, AMD claims that Ryzen 4000 offers almost double the power efficiency over its predecessor in terms of performance per watt, which should result in significant battery life gains. In fact, AMD claims that its performance efficiency gains are so large that the 45W Ryzen 4800H can outperform the 95W Intel i7-9700K desktop processor in some workloads.
Another area where AMD trailed Intel in Ryzen 3000-mobile era is OEM adoption. There were simply fewer Ryzen-based laptops on the market compared to their Intel counterparts. That is set to change with Ryzen 4000, with AMD claiming that Ryzen 4000 Mobile will appear in the first systems in Q1 2020, and in more than 100 systems total this year. Specifically, AMD announced upcoming Ryzen 4000 laptops from Lenovo, ASUS, Acer, and Dell, with more to follow.

As the saying goes, I’ll believe it when I see independantly verified tests. But, if those are anything like the slides, these chips are going to be awesome.
Wonder why they went with older gen graphics when they already had a 7nm implementation of the new stuff and they didn’t have one of the old stuff.
Do we know if these are multi chip modules with a compute die and an I/O die? Maybe the I/O die is on 12/14 nm and the graphics are on there instead of the 7nm CPU die? (gross speculation)
AMD has been crushing Intel in all other categories but wasn’t able to in mobile processors specifically single thread performance and power efficiency was behind Intel’s.
Now since both of these issues have been resolved, as said by the AMD, this should be great thing for customers as they have choice in laptops for getting AMD or Intel.
