AMD Ryzen 2 @ Ryzen 2 Key Features Part 1
2nd Gen Ryzen @ Ryzen 2 Key Features Part 1
The AMD Ryzen 2 processors are based on an improved Zen microarchitecture, what AMD calls the Zen+ microarchitecture. Let’s take a closer look at what’s new with the 2nd Gen Ryzen processors!
2nd Gen Ryzen @ Ryzen 2 Tech Briefings
This time, we have not one, but TWO, tech briefings on the 2nd Gen Ryzen processors. This one was recorded at the March preview event in Bangkok, featuring Kevin Lensing (AMD Corporate Vice President and General Manager, Client Business Unit) and James Prior (AMD Senior Product Manager).
And here is an online tech briefing by Robert Hallock, AMD Head of Global Technical Marketing.
AMD Zen+ Microarchitecture
The 2nd Gen Ryzen processors are based on the improved AMD Zen+ microarchitecture, which delivers slightly better performance, with lower cache and memory latencies :
- 3% more 1T IPC (instructions per second)
- 13% lower L1 cache latency
- 34% lower L2 cache latency
- 16% lower L3 cache latency
- 11% lower memory latency
- Official support for JEDEC DDR4-2933
12LP Process Technology
The 2nd Gen Ryzen processors are fabricated using the 12LP (12 nm Leading Performance) process technology from GlobalFoundries.
This is really a 14 nm process, with improvements and a tighter pitch, so the die size and transistor count remain the same. However, the improved process allows for these improvements :
- top clock speed increased by 250 MHz
- “all core” now overclock around 4.2 GHz
- CPU voltage is reduced by about 50 mV at all clock speeds
- up to 11% lower power consumption, compared to 14 nm
- up to 16% better performance per watt, compared to 14 nm
Precision Boost 2
Precision Boost 2 is one of the biggest improvements in AMD SenseMI. It replaces the old 2-core boost model, with a linear boost model. This allows for much greater performance for games and applications that use more than 2 cores.
Precision Boost Overdrive
James Prior revealed that AMD will introduce a feature called Precision Boost Overdrive in the future. The motherboard will be able to communicate its actual capabilities to the 2nd Gen Ryzen processor, allowing for better boost profiles and a relaxed vcore limiter with better motherboards.
Extended Frequency Range 2 (XFR 2)
XFR 2 boosts the 2nd Gen Ryzen processor’s performance by 4-7%, depending on the performance of the installed CPU cooler.
