They are saying €440, which is roughly £400 for this model... OCUK has raised prices on the 8700k to £390 and the 8086K to £420...the 8600K is £120 less at £270... so even if you was to say the difference between the HT and non HT variants was £100 being generous, that would put the 9900k at £500, again i wouldnt be surprised to see it £550+
Yeah these prices have been rumoured for a while now, its typical about how someone like Intel reacts to competition, they are selling a lot less retail CPU's because AMD are now chewing up about half the sales with Ryzen so the reaction is not just to match AMD 'for now' on core counts but also push the prices up to make up the difference in the sales revenue they are losing to AMD.
