There are three main differences between dual-processor servers and single-processor servers. This article will explain these differences in detail.
Difference 1: CPU
As the names suggest, dual-processor servers have two CPU sockets on the motherboard, enabling the simultaneous operation of two CPUs. On the other hand, single-processor servers have only one CPU socket, allowing only one CPU to operate.
Difference 2: Execution Efficiency
Due to the difference in CPU quantity, the efficiency of the two types of servers varies. Dual-processor servers, being dual-socket, generally exhibit higher execution rates. In contrast, single-processor servers, operating with a single thread, tend to have lower execution efficiency. This is why many businesses nowadays prefer dual-processor servers.
Difference 3: Memory
On the Intel platform, single-processor servers can utilize ECC (Error-Correcting Code) and non-ECC memory, whereas dual-processor servers typically employ FB-DIMM (Fully Buffered DIMM) ECC memory.
On the AMD platform, single-processor servers can use ECC, non-ECC, and registered (REG) ECC memory, while dual-processor servers are limited to registered ECC memory.
Additionally, single-processor servers have only one processor, whereas dual-processor servers have two processors working simultaneously. Therefore, in a certain sense, dual-processor servers are considered true servers. Although single-processor servers may be cheaper in price, they cannot match the performance and stability offered by dual-processor servers. Dual-processor servers can also maximize cost savings for businesses, which is highly appreciated. They represent technological progress. Therefore, when selecting servers, enterprises should seriously consider dual-processor servers.
The above information explains the differences between dual-processor servers and single-processor servers. Hopefully, this article will be helpful in enhancing understanding of these two types of servers.
