The AMD Ryzen 9 4900HS is a high-performance mobile SoC for big and relatively heavy laptops that consumes less power. This mobile CPU, like all other Ryzen 4000 APUs (Accelerated Processing Units), is based on the Zen 2 architecture and is built using TSMC’s 7nm processing technology which greatly improves its performance and power efficiency per Watt. The CPU has a default TDP of 35W for higher performance per watt with a maximum operating temperature of 105oC.
The Ryzen 9 4900HS processor features a total amount of 4MB for L2 cache and 8MB for L3 cache per core. It supports PCIe version 3.0 connectivity which is used to communicate between the chipset and storage devices or other components. The chip also supports a dual DDR4 memory channel that operates up to 3200MHz as well as an LPDDR4 memory controller that runs up to 4266MHz RAM thus saving on power consumption for laptops. Likewise, the AMD Ryzen 9 4900HS comes with Windows 10 operating system (OS) pre-installed and supports multiplicity (x86) in software like Ubuntu and other OS like Linux. Otherwise, support for various operating systems varies depending on the manufacturer.
Furthermore, the processor supports up to 8 cores with SMT (Simultaneous multithreading) Technology, allowing it to have up to 16 threads running simultaneously. The cores operate at a base clock speed of 3.0GHz with turbo boost up to 4.3GHz (with a locked multiplier), which is 0.3GHz and 0.1GHz higher than the base clock and turbo frequencies of the Ryzen 9 4900H respectively.
Both the Ryzen 9 4900HS and the 4900H feature an integrated AMD Radeon Vega 8 Mobile GPU on their monolithic die, with 8 compute units operating at a similar maximum clock speed of 1750MHz. Unlike the AMD Ryzen 7 4800H, the Ryzen 9 4900HS is slightly faster with 150MHz in GPU clock speed and Vega 8 graphics. All these features make the Ryzen 9 4900HS better than average with the ability to handle very demanding tasks like content creation and gaming.
According to Cinebench R20 results, the Ryzen 4900HS is not only the fastest in multicore performance but also in its single-core performance when compared against Intel Core i9-9880H processor with an 8-core design. The 4900HS is 35% faster than Intel Core i9-9880H in multithreaded tests, 7% faster in single-threaded tests, and a 30.43% processor speed. The chip is also more efficient with a higher performance per watt of power used. Similarly, the Ryzen 9 4900HS crushes Intel Core i9-9750H, which is popular with ultrathin laptops.
