It has been known for months that Intel will launch a new breed of Haswell processors known as Haswell Refresh but until this moment the actual release date was unknown. Well, now everything is official and Intel has confirmed the day – May 10.
The new chips will be accompanied by a large number of Z97 chipset-based motherboards that will fully support the new processors. As expected both the new mainboards and chips will support the popular LGA 1150 socket. Do not expect huge performance gains though – the new processors will come with increased clock speeds (between 100-200 MHz depending on the model) and will be represented by Core i7, Core i5, Core i3, Pentium and Celeron models.
As to the Z97 chipset the only new thing that it will bring is support for M.2 SSDs, which on the other hand will increase SSD speed as the M.2 form factor allows data transfer rates of up to 1000 MB/sec which is twice as much when compared to the fastest current SSDs.
