Intel Atom

Intel Atom processors are very economical processors that are used in netbooks, smaller notebooks and mini servers. Atom processors starting with an E are intended for private use and have an internal graphics card. They have 1-4 physical cores and mostly support low-voltage RAM, for example LPDDR4, as well as normal modules.

The new Atom C series, on the other hand, is intended for use in mini servers or web servers. Intel Atom C processors can provide up to 8 physical CPU cores, but like the E series for private use, all Intel Atom processors do not have these Hyper-Threading Technology. The fastest 8-core Intel Atom C2750 should be about half as fast as an Intel Xeon 1220 v3 with a quarter of the energy consumption.

For the first time, the Intel Atom C series supports up to 4 modules with 16GB each, i.e. a total of 64GB DDR3-1333 RAM, which results in a memory bandwidth of 25.3GB/s. Intel Atom processors are often advertised with a maximum RAM support of only 8 GB. In reality, however, these systems can also get by with 16 GB, sometimes even 32 GB of RAM. However, since the Intel Atom processors form the entry-level segment of Intel processors, the official amount of main memory is usually reported as low on purpose.

Contrary to Intel Celeron and Intel Pentium processors, which are mostly based on the current Intel Core i series, the Intel Atom processors are independent developments. These are characterized by an even better energy consumption and the capability also in systems that are passively cooled (i.e. without a CPU fan and only with a heat sink). Modern Intel Atom processors do not have to be slow and are usually also suitable for office PCs and NAS systems.
