Our legacy tests represent benchmarks that were once at the height of their time. Some of these are industry standard synthetics, and we have data going back over 10 years. All of the data here has been rerun on Windows 10, and we plan to go back several generations of components to see how performance has evolved.

The Ryzen 1600X has the same theoretical frequencies as 1800X (on paper) minus 2 cores. Both Ryzen 1700X and 1700 have lower frequencies than 1600X. As to why the 1600X shows slightly better results than 1800X in some single-core tests it's probably due to a combination of lower power consumption(less heat) XFR and binning.Read this: http://www.anandtech.com/show/11244/the-amd-ryzen-...

All, I have come across something interesting and wondering if it is only me. I just received my 7820x and was playing around with overclocking and I have to question Intel's claim that the CPUs are "Fully Unlocked". Using an Asus Strix-E X299 MB I adjusted my overclock to 4.6Ghz and then booted successfully and started my stress testing. I noticed my clock speed was bouncing between 4.3 and 4.6 so I thought maybe speedstep was interfering and went into BIOS and turned off SpeedStep, TurboBoost and C-states. When I booted back up I received an error for the TurboBoost utility (expected) but my speed was at the stock 3.6Ghz and the Intel Extreme Utility showed the same but also showed my multiplier should be set at 46. I went back into BIOS and enabled "TurboBoost" and upon reboot CPUz/Intel utility both showed speed at 4.6Ghz. My issue with the "Fully Unlocked" claim is that an OC should not be dependent on a software driver. I have confimed this by the fact that when I boot Linux the OC is not applied.leeymcj - Sunday, September 3, 2017 - link
I have a question, so all the cores are equipped with dedicated AVX register? (cost ~15% of area for each of them)gogi95 - Wednesday, September 27, 2017 - link
what is replacement algorithm used in Intel core i9?
