AMD’s Ryzen Mobile APU
In 2017, Advanced Micro Devices (AMD) launched Zen CPUs (central processing units) and Vega GPUs (graphics processing units) on the 14nm (nanometer) node, marking a process node transition from its predecessor technologies that were built on the 28nm node.
While AMD’s Ryzen desktop CPUs were received well by customers, its Vega GPUs faced manufacturing issues due to HBM2 (high bandwidth memory) and failed to deliver significant performance improvement over NVIDIA’s (NVDA) products.
AMD is set to launch Ryzen Mobile APUs (application processing units) that would integrate Ryzen CPU and Vega GPU on one chip. These new APUs are based on Raven Ridge architecture. Raven Ridge APU would first appear in low-end and mid-range laptops by the end of 2017. This means mobile variants of Ryzen 5 and 3 would launch before mobile variants of Ryzen 7.
AMD claims that Raven Ridge APUs would deliver up to 50% more CPU performance and 40% more GPU performance while consuming only 50% power compared to its predecessor, Bristol Ridge APUs. Raven Ridge APU was tested on Geekbench and the leaked results show that AMD’s claims are true.
Leaked benchmarks testify AMD’s claims
AMD’s Ryzen 5 2500U Raven Ridge APU was tested against an HP Inc. (HPQ) Elitebook 745 G4 powered by the AMD Pro A12-9800B four-core Bristol Ridge APU on Geekbench. The benchmarks were leaked and were reported by wccftech.
The test showed that the AMD Ryzen 5 2500U was 56% faster on single-threaded workloads and 90% faster on multi-threaded workloads. These benchmarks testify AMD’s claims of 50% performance improvement.
The above benchmark is for four-core/eight-thread mid-range Ryzen 5 2500U APU. This means that the high-end eight-core/16-thread Ryzen 7 Mobile APU due to launch in early 2018 would be faster.
Next, we will look at AMD’s efforts in the data center market.
