Ok... But new IGP is still shitty :P

omg wth ,, intel joking !! 8.9 >>>>>9.1 ???!!!!!

I don't see how the Haswell i7 won. The benchmarks were extremely close: there have been other comparisons where benchmarks were "too close to call" before and no winner picked. seems inconsistent to declare winners on things so close and no calls on others with identical closeness.

in the end of page the gpu values are written wrong order: GPU clock speed 350 MHz 650 MHz but it must be GPU clock speed 650 MHz 350 MHz

77/88W is TDP not the power consumption.

3770K 77W 4770K 87W where do you get 65/115? thios test is a big fake

Intel HD4600 is nearly 2x more powerful than the HD4000 on the 3770k. Chill. The gpu frequency boosts under load.
Constantin (09:47 AM, July 22, 2013)
what to do? fu i had already bought mother motherboard and it only support 4th gen. i hope dual processing will do his to benefit 3770. ill overclock it at 4.5 with water cooling for stability. i hated 4770's gpu clock speed. wtf im going to use integrated memory for first months with 2 monitors :(
