Intel Xeon Scalable Xeon Silver 4210R
The Intel Xeon Silver 4210R is a high-volume 10-core, 20-thread entry server processor from the 2nd Generation Intel Xeon Scalable (Cascade Lake Refresh) family. Operating at a 2.40 GHz base clock and boosting up to 3.20 GHz with a 13.75MB L3 cache and a low 100W TDP on Socket LGA 3647, it replaced the original 4210 with higher clock frequencies at a lower cost. It supported 6 channels of DDR4-2400 memory and 48 lanes of PCIe 3.0, making it one of the most widely sold CPUs in budget dual-socket rack and tower servers (such as Lenovo SR650, SR630, ST550, and Dell R740/R640). Widely available on the second-hand market, buyers should inspect LGA 3647 gold pads.
