Small but significan­t upgrades

AMD Ryzen 7 2700X

- By Koh Wanzi

AMD’s secondgene­ration Ryzen processors are an iterative upgrade, but they do a good job shoring up the key weaknesses of the rstgenerat­ion chips. The Ryzen 7 2700X sits at the top of the new mainstream, boasting 8-cores/16-threads and a 4.3GHz boost clock (up from 4.0GHz on the Ryzen 7 1800X.

It uses GlobalFoun­dries’ 12nm LP process, which can o er 10 to 15 percent better transistor performanc­e than preceding nodes. This allows AMD to extend the clock speed range and reduce the current required at all frequencie­s, resulting in higher overall clock speeds. One of the key weaknesses of the rst generation Ryzen processors was its relatively weak performanc­e in games at 1080p, so higher overall clock speeds definitely help alleviate that.

The other big feature is Precision Boost 2, an improved frequency-boosting algorithm that lets each core run at the highest possible frequency. It no longer distinguis­hes between dual-core and all-core boost frequencie­s.

Instead, it’s more opportunis­tic, relying on

Dynamic Voltage Frequency

Scaling (DVFS) technology and using data on CPU temperatur­e, current, and load to determine boost speeds.

Overall, the frequency curve is smoother, and there’s no longer a steep drop-o when moving from a dual-core boost to an all-core boost.

Zen+ also features design optimizati­ons to speed up access to cache and memory, which can help boost performanc­e in latency-sensitive tasks. In addition, the Ryzen 7 2700X also supports DDR4-2933 memory now, up from DDR4-2667 before.

All told, AMD has done a commendabl­e job with its second-generation Ryzen to close the gap in IPC performanc­e, as evinced by single-threaded Cinebench scores. Intel’s Core i7-8700K is around 12 percent faster than the Ryzen 7 2700X, but the 2700X is further ahead in multi-threaded performanc­e, with a whopping 24 percent advantage.

Furthermor­e, the Ryzen 7 2700X is a big step up from the 2700, especially since the latter’s low 3.2GHz base clock hurts it in certain workloads that are sensitive to clock speeds. The 2700X is also just $40 more expensive, so it makes plenty of sense to just pony up for it. It comes bundled the Wraith Prism cooler as well, an impressive specimen of a stock cooler that boasts RGB lighting and fairly robust cooling capabiliti­es.

A capable all-rounder to handle just about everything from gaming to video encoding and streaming.
