The VIA Centaur CHA was a server/workstation processor with 8 cores, that was never released. It is part of the CHA lineup, using the CNS architecture with VIA Socket 2084. To further increase overall system performance, up to two Centaur CHA CPUs can link up in a multi-processor (SMP) configuration. Centaur CHA has 16 MB of L3 cache and operates at 1200 MHz by default, but can boost up to 2.5 GHz, depending on the workload. VIA is building the Centaur CHA on a 16 nm production process, the transistor count is unknown. The silicon die of the chip is not fabricated at VIA, but at the foundry of TSMC. You may freely adjust the unlocked multiplier on Centaur CHA, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 70 W, the Centaur CHA consumes typical power levels for a modern PC. VIA's processor supports DDR4 memory with a quad-channel interface. The highest officially supported memory speed is 3200 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Centaur CHA uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card.
Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, VIA has added support for the newer AVX2 and AVX-512 instructions, too.
