AMD Ryzen 7 2700X/Ryzen 5 2600 review posted ahead of launch

Published: Mar 16th 2018, 19:06 GMT   Comments

A review posted at SiSoftware website was quickly removed, but here’s a copy of all important bits.

Sorry, no gaming benchmark here.

AMD Ryzen 7 2700X & Ryzen 5 2600

The review focuses on R7 2700X vs R7 1700X comparison. The most significant change in the architecture is obviously a new smaller node (12nm vs 14nm), but AMD also brings DDR4-2933 MHz memory support to Ryzen family, which should improve compatibility and overall performance.

The specs chart posted by SiSoftware provides a confirmation to TDP and clocks.

Memory Speed (MHz) Max
2400 / 29332400 / 29332400 / 26662533 / 2400Ryzen2 how supports up to 2933MHz (officially) which should improve its performance quite a bit – unfortunately fast DDR4 is very expensive right now.
Cores (CU) / Threads (SP)8C / 16T6C / 12T8C / 16T4C / 8TRyzen2 like its predecessor has the most cores and threads; it thus be down to IPC and clock speeds for performance improvements.
Speed (Min / Max / Turbo)2.2-3.7-4.2GHz (22x-37x-42x) [+9% rated, +11% turbo]1.55-3.4-3.9GHz (15x-34x-39x)2.2-3.3-3.8GHz (22x-34x-38x)0.8-4.0-4.2GHz (8x-40x-42x)Ryzen2 base clock is 9% higher while Turbo/Boost/XFR is 11% higher; we thus expect at least about 10% improvement in CPU benchmarks.
Power (TDP)105W65W95W91WRyzen2 also increases TDP by 11% (105W vs 95) which may require a bit more cooling especially when overclocking.

AMD Ryzen 7 2700X & Ryzen 5 2600 benchmarks


According to SiSoftware reviewer Ryzen 2000 brings welcome improvements in bandwidth and latency, which should further improve with new BIOSes.

Ryzen 2000 supports 2933 MHz DDR4 memory out of the box, which should provide an overall improvement and better experience (in gaming).


Ryzen2 is a great update that will not disappoint upgraders and is likely to increase AMD’s market share. AMD is here to stay!
