Intel Core i7-4770K Review – Haswell on Desktop

4770K Review

Intel Haswell Lineup & Core i7-4770K:

As yet, Intel has only launched quad-core Haswell parts. The dual-core, low voltage, low end parts will be launched later this year. The desktop quad core parts are classified into Core i7 and Core i5 families. Both families have 6 members each.

Starting from the top of the product stack, we see six Core i7 parts. These feature four physical cores with HyperThreading technology resulting in four more virtual cores. This family is leaded by the Core i7-4770K. It’s an unlocked processor mainly focused on the enthusiast community. It is followed by the slightly slower Core i7-4770 which is basically a locked version of its bigger brother with 100 MHz slower base clock. Both the chips have 84W TDP. We are provided with the top-dog 4770K for evaluation. It looks pretty much like all other Intel processors, nothing new here.

Then we’ve the Core i7-4770S and 4770T. These are slower and low power versions of their bigger brothers. The 4770S has a TDP of 65W while the 4770T sits at 45W. These are followed by the 4760T, which is a 35W part.

All of the Core i7 Haswell chips have HD Graphics 4600 apart from the 4770R which has GT3e class Iris Pro graphics. It is also the only Core i7 chip to be using the BGA design.

Next up are the six Core i5 models. There is nothing surprising here apart from the absence of HyperThreading and one unlocked Core i5-4670K chip. TDP of Core i5 chips range from 84W to 45W.
