Intel Xeon E3-1280 v5

The Xeon E3-1280 v5 is a high-end quad-core desktop processor based on the Skylake architecture, which was announced in August 2015. The CPU, which is manufactured in a 14 nm process, runs at 3.7 up to 4.0 GHz and can execute up to 8 threads simultaneously thanks to Hyperthreading. Contrary to the consumer Core i7 Skylake CPUs, the E3-1280v5 has no integrated graphics card.

Architecture

Intel uses Skylake to replace both Broadwell and Haswell and therefore once again uses one core design for all TDP classes. Several improvements of the Skylake architecture include bigger Out-to-Order-Buffer, optimizations for pre-fetching as well as bigger gains by Hyperthreading. However, the changes are small for a "Tock" – a new micro architecture – in general, so the per-MHz performance is only between 5-10 % (compared to Haswell) or less than 5 % higher (compared to Broadwell), respectively.

Performance

The performance is between the Intel Core i7-6700 (3.4 - 4 GHz) and Core i7-6700K (4 - 4.2 GHz). Even the most demanding applications and games are no problem for the high-end CPU.

Power Consumption

Intel specifies the TDP with 80 Watts due to the dedicated integrated GPU.
