It might have been a long four year development cycle but AMD is finally back to reclaim the throne as the leader of the CPU market with the all-new Ryzen processors. AMD says that Ryzen is capable of delivering the same performances as Intel’s most expensive champions at half the price. We're going to test those claims today by looking at the AMD Ryzen 7 1800X Summit Ridge, AMD's fastest 8-core processor till date.
Architecture and Specifications
These past years have been harsh for AMD. Even their best FX processor couldn't match up to Intel's mid range offerings. Which allowed Intel to get away with new CPU launches with moderate performance gains. AMD’s latest Ryzen processors are based on the 14nm FinFET fabrication process, which is one of the reasons why this powerful chip has an impressive TDP of just 95W.
The new Ryzen 7 8-core processor portfolio consist of the Ryzen 7 1800X, the Ryzen 7 1700X and the Ryzen 7 1700 – all are unlocked for your overclocking needs. There are no non-overclockable processors like Intel's “K” codenames, however, the “X” at the end of a Ryzen processor represents XFR mode which means the chip is capable of going beyond the “Precision Boost” clock limits, provided that you have fitted the rig with liquid cooling. Precision Boost is basically AMD’s version of Intel’s Turbo Boost mode. The AMD Ryzen 7 1800X is designed to provide base speeds of 3.6 GHz and top up to 4GHz in Precision Boost. Each core on the Ryzen handles two threads for a total of 16 computing threads- far more than what the previous AMD FX-8370 offered.
For those who are looking to upgrade, keep in mind that the new AMD Ryzen processors are based on the new AMD AM4 CPU sockets - which means that you will need to invest on new motherboards. Additionally, the new Summit Ridge processors will only support DDR4 memory modules. The new platform also brings support for existing PCIe 3.0, USB 3.1 Gen2, NVMe and SATA Express.
AMD has stuffed some interesting technologies on the new Ryzen that helps bring out the best. For example, Ryzen comes embedded with sensors to monitor CPU temperature, speed, and voltage, and, adaptively control the processor in real time. The process is dubbed “Pure Power” and helps enabling lower power consumption for lower loads while maintaining the same performance.
Next is Neural Net Prediction, which AMD claims is a true artificial network inside every “Zen" and capable of modeling decisions that are based on software code executions. The network can anticipate future decisions and pre-load the CPU instructions for faster executions.
If you’re an engineer, you can easily guess what this is. Smart Prefetch is capable of anticipating the location of future data access points, depending on the access codes. This process then prefetches vital data into the cache for immediate use. BThe Ryzen 7 1800X features 16MB L3 Cache and 4MB L2 Cache.
We tried out AMD's new Ryzen Master application that provides information on temperatures, clock speeds, CPU voltage, RAM voltage, RAM clock speeds and more. You can disable some of the cores on the Ryzen within the app itself, and tweak the speeds according to your will. As for the temperatures, the Ryzen 7 1800X stayed between 55 to 65 degrees for normal workloads. Stress testing the CPU with RealBench, we recorded temperatures of up to 82-degrees using Ryzen Master.
