Even less improvement than expected
By CRT
Quick Review:
While the i7-4770 is a solid processor for desktop users seeking power and bang for the buck and not concerned about the highest clock speed, it is not worth the upgrade if you are on a Sandy Bridge or newer CPU. I upgraded from a much older platform and I would have waited for the 2014 Haswell-e/Haswell refresh chips if the capacitors in my old motherboard had hung in a little longer.
Pros:
+ Supports Intel's Transaction Synchronization Extensions (TSX): This is not supported by the initial K series Haswell offerings and represents a capability that, as an executive responsible for software development, I would leverage in any effort where I could not justify the investment in fine-grained thread synchronization. I expect that game, CAD and multimedia developers are going to be looking to leverage this. As of this writing, this is the fastest consumer chip that supports it.
+ Good performance relative to current offerings: Stock i7-4770 chips do well on benchmark and real world tests. As of this writing (July 10,2013), cpubenchmark.net reports an average CPU Mark of 10,126. That is higher than any stock chip under 580USD, even beating the 4770k at stock speeds.
Cons:
- Surprisingly high retail price at introduction for what it is, I paid 310USD with an Intel box price of 312USD - expect prices to drop as initial fervor dies down and the Haswell line matures.
- Potentially superseded quickly by the i7-4771 (same capabilities with higher speed, possibly driven by improvements in binning with process maturity).
- Surprisingly disappointing performance improvement over previous generations (particularly memory operations).
- Extremely limited overclocking.
Neutral:
o Requires an LGA1150 motherboard - you can't reuse your old one if you wanted to, but LGA1150 chipsets natively have greater peripheral support
BACKGROUND
If you are reading this than I expect you either typically build your own PCs, are considering your first build or are considering upgrading an existing LGA1150 PC (assuming you are reading this in 2014 or later). In each of these cases, you are not the typical user so I will not waste time on basics or information that is available elsewhere. I will give you my opinions and the reasoning behind them and hope they will help you making your own informed decision.
I have been building and tweaking PCs since the early 1990's, but I have only done a half dozen builds for personal or family use. For my primary desktop I tend to build 1 tier from the top (enthusiast, high bang for the buck) and keep it for a long time. It takes me about a day to build a machine and get the OS to boot, but it seems like it takes months before I have the applications fully configured. This build replaced a late 2003 Pentium 4 3.2GHz Northwood Socket 478 build. Yep - almost 10 years. And I actually use my machine - Catia, heat transfer simulations, photoshop CS, HDTV video capture and editing, large MS project plans, various SW development environments and the standard Office applications. I do occasionally game, but not a lot of FPSs. The Socket 478 machine performed as needed until late 2012 when the lack of 64bit and being limited to 2 concurrent threads became an issue (I have access to other hardware, so it was never a road block).
While the new i7-4770 based machine is faster, I am surprised by how little improved it is in real world applications. The most conservative general application of Moore's law says that the new machine should be able to process about 30 times as much information (double every 2 years over 10 years). Having lived with the new machine for few weeks now I am convinced that it is not that much faster. I have used PassMark's Performance Test to benchmark and maintain my personal machines since 2001 so I can provide some objective comparisons in addition to a thumb in the wind estimate...
Using Performance Test v5 with the 4770 machine running 8 threads vs. 2 threads on my old 3.2GHz P4
CPU Mark: 7146.7(i7-4770) vs 665.0(P4) - about 10.75 times the CPU Mark of the old machine
With the 4770 machine running only 2 threads its rating drops to 3343.3 (~5x)
With regards to the built in 4600 graphics - the P4 at the time of testing was sporting a Radeon HD 3800 AGP 8X...
3D Graphics Mark: 2415.0 vs 2358.8 (almost no change)
2D Graphics Mark: 260.8 vs 114.3 (2.25x)
This is a bit of an unfair comparison as a midrange modern dedicated graphics card would likely improve the new machine's performance by an order of magnitude, but it does put Intel's onboard GPU in perspective.
And the real disappointment - memory...
Memory Mark: 992.7 vs 564.9 (~1.75x)
The new machine has much more memory and PerformanceTest 5.0 is 32bit so the new machine has considerable addressing overhead handicapping it, but this really shows how little difference there is between ancient low latency DDR-440 and comparatively high latency modern DDR3-1866.
There is one category where we see the type of improvement we would hope for after 10 years - storage performance. Disk access has always been a bottle neck for me so the P4 was loaded with two Raptors in a RAID0 configuration for the primary boot and application drive. The 4770 machine has a single SSD. The result:
Disk Mark: 19406.6 vs 418.2 (~46x)
The overall PassMark rating of the new system in PerformanceTest v5 (running 8 threads) is 6322.9 versus 677.3 or slightly over 9 times the performance of the old P4 machine.
These numbers back up the way the new machine feels - much faster, but not shockingly so. In fact, shockingly disappointing would be more accurate.
Did I get a bad 4770? Bad motherboard? Bad memory? Should I give up my job as an engineering executive and go back to playing with Legos because I can't even build a PC? To answer that, let's see how the new machine compares against modern machines. Using the current version of Performance Test (v8.0) yields the following results...
PassMark Rating: 3,227
CPU Mark: 11,114
2D Graphics: 1,120
3D Graphics: 559
Memory Mark: 2,961
Disk Mark: 4,266
These numbers are solid. In fact, with the exception of the 3D Graphics, this machine outperforms the other 71 i7-4770 based systems on cpubenchmark.net as of this writing. And the i7-4770 is arguably the fastest stock chip you can get for under 580USD. This makes the lack of progress over the past 10 years even more clear.
My take is:
Unless you have to have a new desktop now, you really should sit this round out altogether - Intel did. The lack of TSX support on the K-series takes them out of play. I am doubtful of the real world improvements of the Ivy Bridge-e as well. If you have a Sandy Bridge, or a Sandy Bridge-e - in my opinion you built at the right time. We have two 2600K based machines and they will serve in their roles well for many years. My plan for my personal desktop is to take a good look at the Haswell-e chips after the prices stabilize (along with DDR4) - maybe sometime in 2015. If I like what I see, the i7-4770 will be transitioned to our HTPC and I will build a new desktop then. That will give me 2 years with this hardware on my desk - about 1/5 of what I got out of my last desktop build.

Solid Processor, Modest jump from Gen 3, Not for overclocking
By Amadeus B. Klein
This is Intel's 4th Generation i7, the 4770 is a direct replacement of the 3770. This CPU is not meant for overclocking (does not have an unlocked multiplier), you want the Intel Core i7-4770K Quad-Core Desktop Processor BX80646I74770K for that.
That said you will need a new motherboard to upgrade from any of the earlier generation CPUs as this generation uses the 1150 socket while the other 3 used different ones. One nice thing here is aftermarket CPU coolers that fit 1155/1156 sockets will work on this CPU.
This CPU is a Quad Core, 8 thread running at 3.4GHz with boost to 3.9GHz as needed.
It is an 84 Watt CPU. The only currently available faster Intel 4th Gen CPU is the 4770K running at 3.5Ghz (and able to be overclocked thanks to the unlocked multiplier).
It comes with HD 4600 integrated graphics which is an upgrade over the HD 4000 in the 3rd Generation 3770.
Depending on what site you read for technical reviews this processor will give an improvement of 1%-20% over a 3rd generation CPU. Personally it seems about a 5%-10% increase in performance in most bench tests I have seen...
When looking at this consider some of the following things:
1) This will require a new motherboard ($100+)so budget that in
2) This does not have an unlocked multiplier, so overclocking is out.
3) With a $300+ price tag and a minimum $100 for a motherboard you will be spending at least $400+ to upgrade so even assuming the best performance increase that's $20 per % of increased performance.
If the price fits what you are looking for and you have no desire to overclock then this might be a solid choice of CPU...
I personally decided on the i7-4770K because if I ever choose to I can overclock it. I upgraded from a 3770K (not overclocked) and didn't really see any real world performance increase (Not overclocked).
I am using it in my media center PC which serves 6-8 TVs, streams music and maintains my media collection. so I am not pushing it with extreme gaming, but I do have it running without a hitch while streaming 1080p 3D movies to 6 TVs at the same time...
If you absolutely must have a 4th Gen i7 Processor and price is a major concern then this might be a good fit, but if top performance is more what you're looking for go with the 4770K... The performance bump over the 1st/2nd gen CPUs does seem worth the price.
If you are happy with your 3rd Gen i7 I would skip the upgrade since it's not that large of a performance boost overall...
Components in my personal Build:
Silverstone Tek GD-08 Case
ASUS Z87-PRO Intel Z87 4DIMM ATX
Corsair Enthusiast Series TX850 V2 850W 80+ Bronze
SAMSUNG 840 250GB 2.5 SATA III
Intel Core i7-4770K 3.50 GHz LGA1150
Kingston XMP 16GB 1866MHz DDR3 CL9 (Kit of 4) XMP
Blu-ray Optical Drive
5 Western Digital Red 3 TB NAS Hard Drive: 3.5 Inch, SATA III (12TB Usable with Raid Config)
ARCTIC Freezer 7 Pro Rev. 2, CPU Cooler
EVGA GeForce GTX 650 1024MB GDDR5 DVI mHDMI Graphics Card

A better deal than the i7-4770K
By coder
This processor is fully featured, unlike the i7-4770K which lacks support for TSX and costs more. The TSX instruction set extension will make multi-threaded applications faster, so despite the i7-4770K's extra overclocking abilities (which are not guaranteed), it may not be the faster processor in all cases.
So just get this i7-4770 instead and get what you pay for. You can also save money on a cheaper motherboard. This processor offers a lot of bang for the buck and still has untapped potential thanks to the AVX2 and TSX features which will be used by future software and thus extend its longevity.
I've observed a fairly consistent 20% higher performance in multi-threaded applications over an i7-2600 so far. AVX2's doubled vector processing power should increase that gap even more once multimedia applications and games make use of it.
