AMD Top-End CPU For Laptops Benchmarks Leak: 8C/16T AMD Ryzen 7 4800HS And AMD Ryzen 9 4900U

AMD Ryzen 4000 Renoir APUs, the 7nm processors based on the ZEN 2 Architecture, have been regularly appearing in the new for quite some time now. The latest to appear online is the AMD Ryzen 7 4800HS and AMD Ryzen 9 4900U. These two CPUs, headed for the premium, AMD-based gaming laptops and notebooks offer desktop-grade performance and yet manage to conform to the strictest of power efficiency parameters.

AMD APUs with Radeon Vega onboard graphics have appeared online previously. These powerful processors have shown to outpace not just Intel’s equivalent products in the mobility segment, but also some desktop variants as well. Now details and benchmarks of two new AMD Ryzen 4000 CPUs have appeared online, and they further confirm that AMD is planning to dominate the mobile computing space. While the AMD Ryzen 7 4700HS is a 35W CPU, the AMD Ryzen 9 4900U is a 15W CPU that outperforms several of its competitors easily.

8 Core 16 Thread 35W Mobility AMD Ryzen 7 4700HS CPU Specifications, Benchmarks, and Features:

The AMD Ryzen 7 4800HS is reportedly the fastest mobility processor in the 7nm ZEN 2 Architecture-based Renoir family. The CPU appears to be similar to the AMD Ryzen 7 4800H. The primary difference between the two is the power draw. While the AMD Ryzen 7 4800H is a 45W CPU, the AMD Ryzen 7 4700HS is a 35W CPU.

The AMD Ryzen 7 4700HS features a base clock of 2.9 GHz and a boost clock of 4.2 GHz along with 16 MB of L3 cache. It comes with 8 Cores and 16 Threads as well as a 7nm Vega GPU with 8 CUs or 512 stream processors.

It is interesting to note just how powerful the upcoming AMD Mobility CPU is in the real world. Reports strongly indicate the AMD Ryzen 7 4800H comes super close to desktop-grade processors. In fact, it reportedly outperformed the Core i7-9700K in the 3DMark Time Spy CPU test. According to a leak on Twitter, the Ryzen 7 4800HS features a Time Spy CPU score of 8730 points which makes it much faster than the Core i7-9700K and should outperform the Ryzen 7 2700X as well.

AMD Ryzen 9 4900U CPU Specifications, Benchmarks, and Features:

While the AMD Ryzen 7 4700HS with Radeon Vega Graphics will power the premium gaming laptops, the AMD Ryzen 9 4900U could be embedded in high-end sleek notebooks where battery life and quite possibly passive cooling, are as important as performance. AMD appears to be leading in the lower end of the power draw segment as well.

The AMD’s lineup of 15W CPUs includes the Ryzen 5 4500U and the Ryzen 7 4800U. However, Lenovo’s latest laptop includes a new, even higher variant, known as the AMD Ryzen 9 4900U. Incidentally, the Ryzen 7 4800U features 8 cores and 16 threads with a base clock of 1.8 GHz and a boost clock of 4.2 GHz. It is quite possible that the Ryzen 9 4900U may feature the same Core and Thread count. However, the CPU would feature even higher clock speeds. Experts indicate the AMD Ryzen 9 4900U may sport a base clock of 2.0 GHz base and 4.4 GHz boost in a 15-25W (cTDP) design.

It is interesting to note that AMD’s Mobility CPUs are increasingly being compared to the desktop processors from Intel. This is because Intel’s upcoming Mobility CPU lineup could be based on the 10nm fabrication node or even the much older 14nm node. These Intel CPUs are quite far behind AMD’s new Ryzen 4000 Renoir Mobility lineup.
