Two months after launching a processor line that put it on much better competitive footing in the notebook market, AMD (AMD) is adding a couple of additional high-end parts to it.
On Monday -- a day on which AMD's stock fell 11.8% amid a market plunge -- AMD unveiled the Ryzen 9 4900H and 4900HS, a pair of 8-core notebook CPUs with integrated GPUs. The 4900H has a 45-watt thermal envelope (TDP) and is now the most powerful processor within AMD's Ryzen Mobile 4000 line, which was unveiled in January. The 4900HS is the most powerful Ryzen Mobile 4000 processor to have a 35-watt TDP.
Like other Ryzen Mobile 4000 processors, the 4900H and 4900HS rely on AMD's Zen 2 CPU core microarchitecture and are made using Taiwan Semiconductor's (TSM) 7-nanometer (7nm) manufacturing process node. And like various other AMD and Intel (INTC) notebook processors sporting 35W or 45W TDPs, the chips are aimed at gamers and content-creators (systems targeting notebook buyers with less demanding needs typically have 15W or lower TDPs).
Whereas AMD's Ryzen 7 4800H processor (previously its top-of-the-line notebook processor) has a base clock speed of 2.9GHz and a boost speed of 4.2 GHz, the 4900H's base and boost speeds are respectively at 3.3GHz and 4.4GHz. The 4900HS respectively has base and boost speeds of 3GHz and 4.3GHz, beating the Ryzen 7 4800HS' speeds by 100MHz.
Those clock speed improvements, together with the improvements that the Ryzen Mobile 4000 line more broadly delivers in terms of instructions per clock (IPC) and power efficiency, put AMD on better footing against Intel's H-series high-end notebook processor line at a time when AMD has been more broadly gaining notebook (and desktop) CPU share.
While AMD claimed in January that the Ryzen 7 4800H outperformed Intel's 6-core, Core i7-9750H processor by up to 5% in single-threaded workloads and up to 46% in multi-threaded workloads, Intel also offers 8-core H-series chips. Also, Intel appears set to launch a new line of H-series processors (based on a CPU platform known as Comet Lake) that deliver meaningful performance gains. Both the existing and upcoming H-series chips are based on Intel's relatively old 14nm process node.
As Nvidia (NVDA) can attest, systems aimed at gamers and content-creators have been a strong point for the notebook market in recent years. The 4900H and 4900HS launches are a sign that AMD, whose desktop CPUs already claim a healthy chunk of the high-end consumer desktop market, is also taking the high-end notebook processor market seriously at a time when Intel is prepping a counterattack.
