Intel Core i7-4770K Review: Haswell Has Landed

Article Index:   

As you probably expect, Intel’s got a host of Haswell-based 4th Generation Core processors coming down the pipe. We’ll have more new to share with you soon regarding mobile and dual-core parts, but here’s a breakdown of the desktop quad-core parts that are on the immediate horizon.

This first batch of Core i5 processors all offer the same max Turbo frequency of 3.6GHz and feature the same on-die Intel HD 4600 series graphics as the Core i7-4770K we’ll be showing you here. Note, however, that the maximum graphics frequency of these Core i5 parts of 1150MHz is a full 100MHz below the 4770K. HyperThreading is not supported on the true quad-core chips, but it is on the dual-core Core i5-4570T (far right). TDPs range from 35w to 84w.

This next batch of Core i5 processors are all quad-core parts, with the same cache and graphics configurations. The only differences between these chips are their base and max Turbo frequencies and their test TDPs. The K-SKU is also fully unlocked for easier and more flexible overclocking. These processors also feature Intel HD 4600 series graphics, but with a maximum GPU frequency of 1200MHz.

And here we have Intel’s 4th Generation Core i7 processor line-up at launch. All of these processors are quad-core parts with support for HyperThreading. The Core i7-4770K is the enthusiast targeted product with unlocked multipliers, and for some inexplicable reason, vPro features disabled. Also note that the Core i7-4770R is the only chip here with Iris-branded graphics. The Core i7-4770R features Intel Iris Pro 5200 series graphics with a max GPU frequency of 1300MHz. The rest of the i7 desktop processors have Intel HD 4600 series graphics with support for max frequencies in the 1200MHz -1250MHz.

The Single-Chip Intel 4th Gen Y-Processor

Intel will also be offering a single-chip 4th Generation Core processor with the CPU and PCH integrated into single BGA package. The 4th Gen Core Y-Processor line as it’ll be known will include 15W and 28W TDPs, with S0ix support, and supports LPDDR3 and DDR3L memory. These chips are designed for Ultra-Thin devices smaller form factors.

Looks like you could use this CPU as a room heater. Yikes!

Lmao XD

just because it runs at a high temperature doesn't mean it heats more than the previous CPUs. in fact, it doesn't. it only runs at a high temp because the heat spreader isn't soldered to the die. there is a bad heat transfer medium betweem them: the thermal paste.

What makes you say that? A full system under load barely pulled over 100w.

Ill stay on budget pc im not really more on heavy work loads :v

This looks like a very worthy successor to Ivy Bridge for sure, however I was expecting (And so was everyone else I can safely say at this point) to get a little more juice out of this TOCK level CPU.

It's still a freaking wonderful thing, but I'm just a little sad we didn't see much more raw performance gains.

Oh well, it's still amazing, and I certainly would not mind getting a rig built with this as its heart, no sign of that happening ever though :P

Intel is mainly pushing Haswell for better mobile solutions and this review is of the desktop chip!

Features like the Iris Pro GMA 5100/5200 will only be available for the mobile versions and support for the full range of S0ix power states will only be supported on the mobile chips for maximum battery life potential.

So expect more bang for your buck with tablets, hybrids, and laptops that use Haswel than the desktop/server versions...

I'm building a Haswell based computer right now! I just got all my parts yesterday!

I'll be replacing the computer in my sig.

Intel Core i7 4770k

2x 120GB Kingston HyperX 3K SSDs in a RAID 0 (Atto bench results show 1.1GB+ read AND write speeds)

2x 4GB G. Skill DDR3 2400Mhz 10-12-12-31 timings

ASRock x87 Extreme6 MB

Corsair TX850M psu

4x 1.5TB HDD in a raid 10

A lite-on Blu-Ray drive

I will be moving my 660 Ti over to do a couple ot benches to see what improvements the new system has over my last one with the same GPU. I want to wait for the 760 Ti to come out to see how it performs, but if I get impatient, I might just buy a 770.

The system is already assembled except for the 4x 1.5TB drives and I haven't moved the 660ti over yet. I'm on igp right now. i also decided to go with Windows 8. I like it so far, but it is taking a little getting used to.

Nice review, Marco and Dave. Very good information. I have to get a new PC for work and school. Plan on building one, and trying to decide the CPU.

I still have my 980x, no reason to change yet.

I came into computer building a firm believer in AMD... mainly due to my lack of funds (what with being a teenager with a part-time job). Still a lack of funds, but the more time I invest into looking at benchmarks and reviews, the more Intel looks like the leader of the pack. How this might change in the future with them investing so much less in the desktop side of things and pursuing the mobile market I don't know, but I plan on Intel being part of my next build. The 8350 is only so good, and with more and more programs taking full advantage of all 8 cores, it's getting better and better... if I was rendering and doing more soft work. Thanks for this very informative review. I look forward to Intel's next "TICK" for desktops.

Dying to get this proc, I have the Asus Z87 Sabertooth still NIB

Ive have this Asus Z87 Sabertooth sitting here for so long waiting to put this 4770K, the board is still new in the box, just cant afford to get a proc, haha. Maybe one day

It's probably not worth upgrading to this from a Core i7-3770k yeah? I think I'll save up for the next generation of Intel cpu
