AMD’s Ryzen offerings

Advanced Micro Devices (AMD) is looking to boost its CG (Computing and Graphics) segment’s earnings with its Ryzen and Vega offerings. AMD’s 14nm (nanometer) Ryzen CPUs[1. central processing units] would compete with Intel’s (INTC) 14nm CPUs. 

AMD is launching three series of Ryzen CPUs for high-end, mid-end, and low-end desktops and notebooks:

  • High-end Ryzen 7 desktop processors built on AM4 X370 motherboards were launched on March 2, 2017. This series includes three processors priced between $329–$499 that compete with Intel’s i7 Broadwell processors priced between $349–$1,050.
  • Mid-end Ryzen 5 desktop processors built on AM4 B350 motherboards were launched on April 11, 2017. This series includes four processors priced between $169–$249 that compete with Intel’s i5 Kaby Lake processors priced between $168–$242.
  • Low-end Ryzen 3 desktop processors built on AM4 A320 motherboards would be launched later in 2017. The series is expected to be priced below $169 and would compete with Intel’s budget offerings.

Advanced Micro Devices (AMD) expects to launch the notebook versions of these three CPUs in 2H17.

How has the Ryzen 7 series performed so far?

All three Ryzen 7 CPUs—1800x, 1700x, and 1700—comprise eight cores and 16 threads. These CPUs deliver better performance than Intel’s i7 Broadwell-E CPUs in multithreaded tasks. This makes Ryzen 7 well-suited for workstation and professional applications.

However, Ryzen 7 underperforms Intel in single-threaded tasks such as gaming. According to third-party reviews, Intel’s cheaper i7-7700k, which is priced at $349, outperformed AMD’s most expensive Ryzen 1800x, which is priced at $499, in almost every gaming benchmark.

More than 300 developers are optimizing Ryzen’s performance, which could improve the CPU’s performance, particularly in gaming.

AMD’s balanced power plan improves Ryzen 7’s performance

Ryzen 7’s gaming performance was better on Microsoft’s (MSFT) Windows 7 than on Windows 10. The performance difference occurred because Windows 7 kept all physical cores awake and put the virtual cores to sleep. On the other hand, Windows 10 kept one physical core and one virtual core awake, putting the rest to sleep until they were needed.

Advanced Micro Devices (AMD) resolved this issue with its new balanced power plan, which changes Windows 10’s treatment of virtual and physical cores by keeping all physical cores awake. This would improve gaming performance for an average gamer.

In a blog post, AMD stated that the balanced power plan improved Ryzen 7’s gaming performance on Windows 10 from 3% to 21% in many popular games. According to AMD’s test results, the biggest performance improvement of 21.6% occurred in Crysis 3.

AMD recently launched its Ryzen 5 series. Next, we’ll see what early reviews say about Ryzen 5.
