Some of our highest tier Dedicated servers are dual-socket and have 2 of the same CPUs installed; these servers are great for very computationally intensive tasks.  On our Dedicated Servers page, the available dual processor/socket servers are listed with a "2x" or "Dual(2)" in front of the CPU model's name, for example, "Dual(2) E5-2670 v2". For clarity, these dual systems are not shown above. However, the total number of cores and threads would obviously be double the value listed in the table.

AES-NI extensions, to speed up encryption calculations, are available on all CPUs released in 2010 or later.

Cores and Threads:

Most of our CPUs include Hyper-threading technology which can divide a physical processor (core) into 2 logical ones (threads). This can help improve performance by allowing a single core to process two separate tasks simultaneously. In addition, having more cores allows your server to do more things at once.

L3 Cache:

An L3 cache is a small amount of high-speed memory stored on the CPU chip itself. The CPU uses this cache to store instructions that are being processed by multiple cores to provide quicker lookups for the processor. As this cache is much faster than RAM, it can help reduce bottlenecks and improve processing performance.

Base Frequency vs. Turbo:

The Base Frequency is the normal clock speed at which the CPU will operate. However, when conditions are right, the CPU will automatically scale up to the faster Turbo clock speed. These conditions are determined by the number of threads or processes, as well as the type of workload the CPU is being asked to do. For example, servers used to host games usually benefit from having a faster clock speed versus having more cores.
