Introducing Arbico Computers' new line of Intel Haswell CPU based custom built PCs
Haswell is the name of Intel's new processor microarchitecture which is the successor to the Ivy Bridge architecture. Haswell processors are expected to have at least a 10% performance increase and up to double the performance of the integrated GPU compared to Ivy Bridge CPUs.
However the main difference with the Haswell processors will be a new socket (LGA 1150). This will mean that if you have an Ivy Bridge CPU, and you wish to upgrade, you will need to by a new motherboard to support the new Haswell processor instead of just swapping out the CPU like previous models.
The new Haswell chips are also able to support Thunderbolt technology (the latest and fastest connectivity platform).
