4770k or 4820k?

[Cuntlicker]

What is the difference in the two? They are the same price but would either one have a benefit to the other? I've never seen anyone pick the 4820k for a build.

[Unhelpful]

You don't really choose the 4820k for the cpu difference, they are very similar, you choose it for the motherboard, it is 2011 as opposed to 1150. So if you want to go 2011 but don't want to spend at least $500 on a CPU the 4820k is the cpu to go for. I would just go 1150 unless you need a TON of PCI-E slots.

[Izaya Orihara]

That is because the 4820k is a 2011 socket CPU. LGA 2011 only has expensive Motherboards which are pretty outdated by now. Go for the 4770k. Also the 4770k is a Haswell over Ivy. Also welcome to the forum enjoy your stay.

I think the best person suited that I know to answer your question is @TheProfosist . He can tell you the benefits of going with a 4820K appose to the 4770K.

[tryphaa]

The 4770k hands down. Odds are you don't need the 2011 features, and Haswell is up to a 10% improvement over Ivy clock for clock.

[SparkySamZa]

at least with the 4820k you do not have to delit it to overclock it and with thr 4820k you get more ram and more bandwidth

That would be like telling the difference between my farts in real world performance

Pretty much this.

 

Or if you want to go with three video cards, as there are 40 PCI lanes available.

Honestly though, not a huge deal.

I'd go with the 4770k if you're on a budget. The CPU's are similarity priced, but the 2011 motherboards are usually more expensive.

It's pretty pointless to get an mATX LGA 2011 board.

[harrynowl]

I'd just get a 4770K.

 

Newer architechture and chipsets.

[SpaceSquid]

4820k mobos are expensive, get a 4770k and spend the savings on your gpu or a ssd.

[Suika]

The difference in gaming power favors the 4770k if I recall the benchmarks, the biggest difference is the socket and chipset that goes with a processor like the 4820k. In most cases, a standard gamer wouldn't need things like extra slots for RAM and PCI. One thing I've heard is that it overclocks like butter (not literally), but I have no first hand experience.

 

The 4820k makes no sense for a gamer.

well i went with my 4930k for video converting and just having the convenience of not deliding ,

Sorry about the late reply I was trying to find the other threads that I had already written a bunch of stuff in.

This one is probably pretty good as its pretty in depth and I link to other threads as well. http://linustechtips.com/main/topic/118482-x79-with-i7-4820k-or-regular-z87-with-i7-4770k/?p=1606485

Video cards are not the only think that uses PCI-E lanes. Once big thing that may start using them considerably will be PCI-E SSDs because as far as what has been leaked about intel's latest chipsets there is no support for sata express.

And yes it is unless you need the 6 core processor and the 64GB of ram in something more portable. Or maybe you have a bunch of high bandwidth single slot devices.

I'd just get a 4770K.

ever since sandy bridge architecture doesnt really mean all that much processing power wise as for teh chipset I myself prefer X79.

4820k mobos are expensive, get a 4770k and spend the savings on your gpu or a ssd.

What do you consider expensive? If your looking at a $200 or even $150 Z87 board you can look into a X79 one fairly easily.

That would be at stock the 4770k is slightly better on OC the 4820K is usually ahead unless you get one of those amazing 4770K's that some of the reviewers and OCer's have.

I guess if your solely gaming but then you could easily go with a 4670K with mATX Z87 board or a 1230v3 and a B85 board if you dont plan to SLI/Crossfire.

Which isn't true. There's an IPC difference of up to 20% in games: http://www.pcgameshardware.de/screenshots/original/2013/09/SC2HotS-pcgh.png

Haswell at 4.3GHz is somewhat IB@5.1GHz..

Most mATX boards only have enough DIMM slots for 32gb of RAM, and lack enough PCI slots to bottleneck the 4770k.

The cores would be the main benefit. Unless you found 16gb sticks.

I can't wait for Kingston's Predator SSD. Should be insane. Though, sadly, I think my next PC is going to be m-ITX due to space restrictions.

You can't bottleneck the cpu really except your network card/storage drives can.

IPC improvement doesnt change per game or anything that would be improvement in that program. IPC is raw clock per clock performance increase when fully utilized. There are a few different ways to find thing but a game is definitely not one. IPC improvement from ivy to haswell is at max 10% but has been shown to be slightly less in a few reviews that I have read.

Also generally IPC improvement is ~15% or less. Since Sandy Bridge its been less since the focus is on power consumption.

Yeah your IPC doesnt change at all but your end result like in a benchmark can. Here's some clock for clock comparisons (http://vr-zone.com/articles/haswell-4770k-vs-ivy-bridge-4770k-4-6ghz/32838.html) although it would have made more sense if both were at stock since Haswells performance/clock ratio is higher but pretty sure we're above 10% in many tests.

People pulled their conclusions from cinebench that only showed a 10% gain but cinebench is irrelevant for gamers under us, we're interested in how much of a difference we can see in games and I've given you an example that we see since sandy bridge to haswell everytime a gain of up to 20% increase with a newer generation.

Neither makes sense if all it's going to be used for is gaming.

tom's hardware http://www.tomshardware.com/reviews/core-i7-4770k-haswell-review,3521.html (they have a few pages so I didnt want to link them)

many of those seem lower than 10% on the highly threaded stuff or right around there.

Well its not the PCI-E slots its the lanes. Many Z87 boards ahave tons of slots but barely any operate at full speed if another one is filled or even if you have some onboard stuff the manufacture decided to add on in use.

[Ryan Leech]

I would personally buy the 4820k

Like I said those synthetic cpu benchmarks dont mean much other than being a basic indicator to compare cpu's like if you're struggling between the 8350 & i5 and if youre aware of games being lightthreaded. Here you see a 15% gain: http://www.pcgameshardware.de/screenshots/original/2013/10/Battlefield-4-Beta-CPU-Benchmarks-pcgh.png and here another 20% difference between a 4770K & 3770K: http://be.hardware.info/reviews/5109/27/amd-fx-9590--fx-9370-review-amds-rentree-in-de-high-end-markt-benchmarks-hd-7970-crysis-3-1920x1080-high
