The tray version of highly anticipated flagship of Intel's next generation Haswell processors, the i7-4770k has surfaced on the webstore of two Dutch stores, MaxICT and TakeItNow. The Core i7-4770K is unsurprisingly currently out of stock and is priced at €330 ($424.88) on MaxICT and €350 ($450.63) on TakeItNow which is of course higher than its predecessor, i7-3770K that currently retails for €316 ($406.85) in the Netherlands.
It is anyone's guess as to whether this price represents confirmation that Haswell will retail with a higher retail cost or if the two stores have simply inflated the price due to the early release date.
The product pages further indicate that the Core i7-4770K is a socket 1150 processor and will have a standard clock of 3.5 GHz. Screengrabs from Hardware.Info.
