AMD Debuts Ryzen 5 2500X and Ryzen 3 2300X For Prebuilt PCs (techreport.com)
AMD announced two new second-generation Ryzen CPUs this morning. From a report: The Ryzen 5 2500X and Ryzen 3 2300X bring Precision Boost 2 and XFR 2 to quad-core Ryzens without integrated graphics, but there's a catch: these chips appear to be available exclusively to system integrators and OEMs for use in prebuilt systems. AMD is debuting the Ryzen 5 2500X in cooperation with Acer in the form of the Nitro 50 desktop PC. AMD says the Ryzen 5 2500X and Ryzen 3 2300X each use a single enabled core complex (or CCX) from the two available on Pinnacle Ridge Zeppelin dies to get their four cores. Recall that the Ryzen 5 1500X instead used two cores from each CCX to get its core count. A consequence of this architectural change versus the Ryzen 5 1500X is that the Ryzen 5 2500X now has 8 MB of L3 cache, down from 16 MB. That puts both the Ryzen 5 2500X and Ryzen 3 2300X on par with the Ryzen 3 1300X and Ryzen 3 1200 on a cache-capacity basis.
So AMD found a defect and had to bin the part. But instead of throwing to the trash they decided to disable to broken silicon and sell the part for cheap - for computers that will also probably be cheap. Both Intel and AMD have done the exact same thing for years. This is news because? New part numbers one needs to remember to avoid?
Binning, as you say has been going on for years and is actually planned from the beginning.
It is almost guaranteed that whatever the hell chip you used to post this, it was likewise binned with either something on it disabled, or at less than the possible performance level because it wasn't up to snuff.
Telling people to avoid these chips is borderline retarded.
