Intel Core i7-4770K Haswell

Some of the boards seem a bit expensive though. E.g. the Asrock Z77-Extreme4 is only 115€, while the new Asrock Z87-Extreme4 is 185€. But MSI have some nice boards that aren't too expensive. Asus-boards are just so ugly, that I can't make myself buy one. Gigabyte boards are a bit costly too, the Z87X-UD3, which used to be lower-end, now costs 170€.

 

- New power saving states (SOi1-2, C6-7)
- Doubled L2 cache bandwidth
- Uncore (Independent Ringbus speed is back like how it was with Nehalem)
- New compute instructions (AVX2 inc FMA3, Gather, improved bit-manipulations, etc )
- 11-16% larger architecture buffer sizes
- More security features
- More ALU and execution ports
- TSX
- Faster and better Virtualization
- Not much faster, but a finally scalable GPU architecture (edram, better CS, MJpeg, Collage)
- New better chipset
- etc...

"not being any different" really?

 

Oh very good to know I have a buyer lined up for my old hardware! Haswell here I come! Now I just have to figure out which motherboard I want.

 

Use better cooler and use same OC , when test who faster , who better .

 

How much difference would be noticed between an i7 860 and a i7-4770K (at stock clocks).

 

I had i7 870, moved to 2600K, was a great boost. So you'd get an even bigger boost. Most notably when gaming and such, same VGA will get more performance. I cannot quantify an exact percentage, but I want to say maybe 25%, if not more, way more. It'll depend on the app too, of course...

 

Wow, OK. I mean, it's still an i7 so even losing 25% is no biggie. But that is quite a difference. I'll still be bottlenecked by a GTX 550Ti though so I guess GTA IV won't notice

 

When I got rid of my 2600K's(I had two), I traded them to users that had AMD rigs running stock, and they were pretty amazed by the difference, so I know that the difference I felt wasn't just a placebo thing.

An I7 860 is only 2.8 GHz, with 3.46 GHZ turbo.

The 4770K is 3.5 GHZ, with 3.9 GHz Turbo.

That is about a 20% non-turbo clock increase, and 12% with turbo. Add in IPC gains, and gains from memory bandwidth, and there's some decent performance improvements to be had when moving up from older platforms. The clock speed alone should see a 10% improvement, at stock.

Once you add in power savings, better USB 3.0 and SATA 6 Gb/s drive performance, I think you'll be pretty happy with that upgrade.

 

Sorry if I'm cluttering up the i7-4770K thread but I'll explain what I'm doing...
I'm building a new secondary PC (currently a Celeron G540 with a GTX295) using some parts I got for cheap off another member here... a really nice Gigabyte motherboard and the i7 860.
Since I'm upgrading the RAM in my main (AMD FX-8350 computer) I'll use the "old" (well not really but you know what I mean) 16GB (2x8GB) DDR3-1333 RAM from that in the i7. I'm also upgrading the graphics in my main (AMD) computer, from a GTX 550 Ti 2GB to a Radeon HD 7850 2GB. I'm going to put the GTX 550 Ti, along with a second one I just ordered off eBay, into the i7 860 build, for SLI.

Since the GTX 550 Ti isn't particularly great, but it's also not horrible, it should be a balanced build. Would you agree?

 

You will feel next to nothing with the 550ti imo. Sooner or later you will eventually swap your CPU of course, but (if you want to game) I suggest you spend your money on a better GPU first.

 

Hell, Nehalem is a good upgrade to those on Phenom 2s.

 

Not much of an uprgade for me

 

How does the load and idle power compare with the 3770k?

 

Idle is comparable or lower than IVB. Load is a bit higher, due to the iVR, but actual CPU consumption is roughly less. I measure power for board reviews via the 8-pin EPS connector only, while I see some sites reporting full system numbers of ES CPUs that match my retail CPU figures via the 8-pin, and since they did not reach higher overclocks than I did(which a CPU with better power consumption should, based on my own samples), I have to question their results.

I have had three chips, two I still have in my possession, and both are retail.

Review using ES are kinda BS, in my books. I don't have any NDA with Intel, so I could tell you the differences between retail and ES, and they are quite big differences, but I'll leave that up to sites that used ES chips for review. All of TPUs reviews were done with retail chips.

 

Do you think a 450 W PSU (this: http://www.hardwaresecrets.com/fullimage.php?image=42969) would be adequate for an overclocked 4770K + overclocked GTX 760?

 

I am not sure. The split 12V rail has me a bit worried, honestly. Personally, I won't build a rig with less than 650W with a mid-high-grade GPU, 850W for dual GPU, 1000W for triple, and 1200+ for quad VGA. I also suggest nothing less than a GOLD-rated unit. I use a 860W Platinum-rated unit supplied by Seasonic for my motherboard reviews. That said, I am a bit over-zealous when it comes to PSUs.

 

What cpu cooler was used in the review?

 

here is the answer

 

Yeah that's the problem I have right now. Built a Nehalem based machine in 2009 and I still can't justify upgrading...

 

Seems we're all waiting for Intel to create a better [performance rather than power efficient] processor. It's ok Intel tacked on a 3+ old gpu... huzzah!!

 

I've been using AMD cpu for the past 15 years, my last buy was 5 yrs ago AMD 4 cores 945 BE.

Last night bought these, i'm sure the diff between my current pc with this new speed pc will be like Ferrari vs family car 1.5cc.

i7-4770k - USD337
ASUS Z87-A LGA 1150
60 GB SDD
1 TB SATA HDD
GTX 670
650W 80 bronze power supply
8GB Kingston 1600Mhz DDR3 RAM
Cooler Master 202 hyper air cooler ( if $$$ avaiable im going to get the corsiar 100i later for overclocking, and use this cooler master for my older system)

Now waiting 2-3 days for the pc to come Yehaaa...

 

Its gonna be more like a cycle to a sr71

 

...and I can completely understand why. I've seen too many bad PSUs. If you have the money to invest in a nice PSU, you should and Seasonic makes excellent units. The last 2 PSUs I've bought were Seasonic and before that was a Corsair and since I haven't had a problem with all 3.

 

I went to wiki to find out the meaning of sr71 lol...

The store where i bought run out of 202 and give me free upgrade to 412s. 2 more days for my 4770k to be tested.

 

This CPU is far better suited for laptops/tablets etc and not desktops.

I'm a bit pissed off that they killed PCI support completely with Haswell -- if they're going to kill support for PCI, at least give people enough PCI-E lanes for all their other peripherals first, x16 lanes is a bad joke, they might as well make all of their enthusiast boards mini ITX.
