I was wondering if I should buy a i7 2700k now or wait for Ivy Bridge i7 3770k, which is expected to come out in a couple of weeks.
Rumor has it that the Ivy Bridge processors will be terrible overclockers due to extremely high temperatures. Source
I have my build ready except for mobo/processor. Got a 620w Seasonic PSU, 8gig DDR3 2133 ram, and an Corsair H60 CPU cooler with 2 Scythe Gentle Typhoons for the radiator. Still havent bought the GPU yet. Still trying to decide if I should go mid-range Kepler or just get a 560ti 448 now. Anyone opinions on this as well?
I am looking to stream with little to no FPS drop so the 10% increase in CPU performance from the Ivy Bridge processors would help. I also plan to overclock to 4.3-4.5 ghz.
Thank you very much in advance.

I would get an ivy bridge motherboard and if you really need to overclock, a sandy bridge processor. getting an ivy bridge motherboard leaves your upgrade path open while still allowing you to use a sandy bridge processor.
Also it doesn't matter what system you have, you will have fps drop. Unless the game you plan to play is extremely GPU limited (almost none are fyi) you'll be limited on the processor side which is what is mostly used for streaming.
|
I don't know about the whole "3770k is hotter thing. Maybe they just got a bad test chip or something. From what I've heard is you get better and cooler overclocks. But then I ask you, why get a 2700k y not a 2600K? You can acheive pretty much same overclocks as the 2700k for $20 cheaper. Even with an H60 you can get decent overclocking temps, 4.3 ghz is really just a multiplier increase. I would say if you can't wait, just get a 2600k, and if you have the patience then get the 3770k.
Depending on what games your playing, if your just playing sc2, then get the 560, if your thinking about other games that are more GPU demanding then go with a 680 or 7970

afaik, ivy bridge and sandybridge are backwards compatible, both 1155 socket.

I'd get the 2700k. If you want to upgrade to ivy bridge in the future you can sell the 2700k and upgrade to ivy. Both use the socket 1155. Also the 2700k is a cherry picked cpu made for overclocking. It's an excellent choice and I use it. I haven't had the need to overclock it yet, so I can't tell you the results. However reviews I've read about ocing it, all have said it ocs amazingly and preforms very well. Also the ivy bridge rumors... rumors are rumors, it could totally blow sandy bridge out of the water, but nobody will know until it's out and benchmarks are available. Choice is yours!

Even at stock freqency it should be more than enough for streaming.
|
About a month ago I bought a 2700K and did not regret it. Ivy Bridge will – at least at launch – not provide a significant performance upgrade, so you would need to wait even longer for higher-clocked models. I can overclock my 2700K with no effort to 4.4 GHz (higher frequencies would require more voltage on my model but I am too lazy to check that out.) Currently I use my computer to play SC2 and stream or make HD casts with stock clock. The CPU can handle it.
With GPUs, it doesn't make sense to wait either. The technology advances, there will always be a better GPU on the horizon.

I dunno seems like everybody posting benchmarks right now has crazy high temps up above 4,5k
@ OP: another thing to consider is that i7-2600ks are $200 at microcenter right now.

wait for reviews
I think IB is 1-2 weeks from release
reports are that IB is hot though and will not OC as well as desired, but wait for reviews

I don't know what you're thinking if you'd not buy a 2600k for $200...
The Ivy bridge seems to be 7%-10% better than the 2600k stock temps, and it probably doesn't OC as well, and for $100-$150 bucks cheaper you'd be crazy not to buy the SB instead.

I don't even have a lga1155 setup yet and *I* bought one, because FUCK that's like a 35%++ discount. Also I need a new computer anyways. 6 year old athlons are good, yes?

It makes me sad that I bought a 2500k for that a couple months back now for $10 more than that D;
|
Or you can do like ghetto old me and if you live near a computer store, go buy the 2600k from there and then return it when you have enough for the 3770k

They're all sold out T_T
i5 2500k is still in stock at the Microcenter near me for dirt cheap though. $180. Like the i7, instore only.

That's a 3570k. But yes, what you said is likely true as well.
|
Isnt a 2700k just a more expensive 2600k with higher stock speeds.
|
Yeah i doubt the core is cherry picked for even higher overclocking as well. pretty sure its just tested to run at its 100mhz gain and off it goes.

Oops, fixed.

I'd go for the i7-2600k - I just recently upgraded my computer and the processor alone will be able to handle pretty much everything for the new few years alone with a low oc.
I Currently run my 2600k at 4.6ghz on air sitting roughly at 60c max on prime95.
- Also whenever deciding should I upgrade or not to, upgrade imo.
Future tip: If you want to wait for the next best thing to release in a month or two you'll never get your computer upgraded.
There will always be better stuff around the corner, buy for what you need now and the next year or 2.
2600k will easily handle that.
For gpu, I dunno if your budget can handle it but a 680gtx can handle anything on ultra high settings w/ 1 monitor currently. That or pick up a 580gtx, a ton of people selling 580's upgrading to 680. You can buy a used one for 300~ or less.
|
If you are going to overclock (a lot), get the 2600K. Ivy Bridge will not be good at heavy overclocking if ES reviews are correct. I don't really see the need for overclocking over 4GHz (which Ivy Bridge should do well) other than flaunting your e-penis :D
So I would go with Ivy Bridge since it will use less power and save you money in the long run.

Welcome to buying technology ^^ That's how it always is.
|
if you can afford it. Go with the 2700k over the 2600k. Higher clock speed, overclocks better being cherry picked like I said. If budget is an issue, go with 2500k.
|
2700k is only cherrypicked for 3.9GHz lol. Just because it satisfies Intel at 3.9GHz, it does not mean it can overclock better than a 2600k lol.
|
As I said. Not cherrypicked to any degree that is meaningful to anyone thats interested in overclocking.
|
lol @ 3.9 That's really awkward.I suppose if you want to overclock exactly to that though :D. haha
|
Why would you buy a 2700k that turbos to 3.9GHz to overclock to 3.9GHz..? Talk about a stupid way to waste money.
|
ANYWAYS, i7 2600k, i7 2700k, or i7 3770k for streaming?
|
Did you not read your own thread...?
|
ಠ_ಠ
Its a little funny actually.

This was the recommendation made on the first page. >.< It still stands.

Note, the $200 2600k deal is over I think. Looks to be $280 online now (still in-store pick up only).
|
Ivy will clock better than sandy IFF you can solve the heat dissipation issue, if you want super high clocks on air without modifying the IHS, go w/ sandy.

This is a matter of personal choice.
The 2600K would do fine. If you want to OC, you could spend some bucks more for a small chance of better OC results on the 2700K. Both are "proven technology". The 3770K is based on that, but still new technology. It has been tested at Intel and should work as intended – some % faster than the 2700K. I myself needed a new CPU a month ago for streaming and did not wait for Ivy Bridge, I rather put my money on that "proven technology" with the 2700K. But maybe you are a person who doesn't want to buy a CPU which will gets phased out and surpassed by a new series within mere weeks. Then you know that you rather wait for the 3770K.
The important thing to know it, that neither of the three CPUs is really a wrong choice. Any CPU delivers what you pay for, and any CPU gets you enough CPU power to stream with good settings (so that you can have good quality without using too much upstream bandwidth.)

Yes. I agree with udgnim. Wait for the reviews. That way you won't kick yourself if you buy the wrong one.
Only a couple of weeks for a lot less pain.

I have recently bought the 2600k and with a h100 pull/push setup.
And i have a awesome OC i am running @ 4.8 Ghz stable for a couple of months now.
Temps under full load are in the range of 70c to 80c i am quite happy.
For the 2700k they are higher binned CPU's so you are certain that it will reach my OC and quite possible higher think about x52 multi. BUT your H60 would probably not be able to keep it cool.
So in conclusion if you are going to wait, wait and see the reviews but if you are going to buy a i7 you might as well buy a 2600k IF you are going for a low OC OR invest in a better cooling solution and buy a i7 and go for the big 5 Ghz
PS: i am able to stream 1080p sc2 with my setup FPS games at 720p

What is wrong with you people's logic? Do you think Intel tests at 5GHz for every chip and than bin according to that? /facepalm

70c-80c is quite high for a 4.8ghz OC.
I also have a 2600k and even at 5.0ghz and 1.52vcore with an H100 (Only pull), I max at about 70c in Prime95.
This is with ambient of about 30c.
The only reason people should buy a 2700k is because they're stupid and don't know how to overclock, or they got tricked into thinking it's easier to overclock.
A 2700k is just a 2600k that they tested at 3.9ghz and it was a some arbitrary low enough voltage or something. This does not carry over to higher clock speeds.

2700K are just slightly better binned 2600K, still on the average the slightly better selected processors. That doesn't mean that the 2700K will outperform the 2600K noticeably.

i7-3770k will outperform the i7-2600k/2700k unless you're aiming for well beyond 4.5Ghz.

No, they're not better binned. Intel tests the chips if they can run at 3.9. If so, they'll be labeled as a 2700k, if not as a 2600k. That's the theory at least. In practice every Sandy Bridge chip will do 3.9 without breaking a sweat, so Intel has to down-label a lot of chips to create the supply of 2600k chips. Which means that in practice the 2600k's and 2700k's come from exactly the same batch of chips and the only difference is the default clock speed they report to the BIOS.

Actuly im not sure if it was tomshardware or anandtech but i read (something along the lines of) they had to pull OC's down to 4.5 on two of their three test rigs for stability. With the almost unnoticable performance per clock gains, it seems 2600k/2700k will actuly outperform ivy i7's by a decent margin if you are pushing overclocking far (>~4.7ghz?)

4.5Ghz is like the practical limit with Ivybridge with most air coolers, as soon as you pass 4.5Ghz holy shit sticks it gets hot. You get around 5% more out of it (speed-wise) and 20% less power consumption. I think it's also only around 10% hotter.
If you're going for like 5Ghz, you need like a water loop most definately ( for 90% of the Ivybridge anyway), and the Ivybridge is like 45% hotter or something at 5Ghz...
So imo, Ivybridge is a great chip for anyone not aiming to overclock over 4.5Ghz, which to be honest is a lot of us.

I dont really see the point of getting it though. Sure, it has better integrated graphics, but that is irrelevant to PC enthusiast crowd (those overclocking i7's atleast) and you wont actuly gain any performance out of it unless you run it at the same clock as sandy. There is no reason to, as if you are limiting by temperature or ease of overclocking, sandy will give you a higher clock speed and thus equal if not more performance. By 4.7ghz, 2600k will have overtaken the 3770k @4.5, and aparantly also have lower temperatures.

The Ivybridge wasn't built to satisfy the PC enthusiast to be honest, it was more of a platform to deliver and test the 22nm manufactoring process. Ivybridge brings gains to everyone who doesn't want to overclock their chips over 4.5Ghz which my guesstimate will be more than 99% of the market considering prebuilt machines, laptops, people who don't overclock/have chips that can't be overclocked and people that overclock under 4.5Ghz.
One could also argue that a PC enthusiast should have a likewise cooling kit which would let their Ivybridge run at 5Ghz.

No CPU is really designed for the PC enthusiast in mind. Intel would be happier if their chip was better than it actually is for any market segment, but it's not.
Regardless, I'd still take an Ivy Bridge over a Sandy Bridge, even for streaming.
By the way, aren't there reports of Sandy Bridge on 4.7 GHz or more degrading after a couple months of 24/7 load? I'm sure some chips can handle that fine because they can do it on a lower voltage, but not every sample. Well anyway, maybe if we were looking at 4.5 GHz on Sandy vs. 4.3 GHz on Ivy (being more conservative), that's not much different than looking at 4.7 GHz vs. 4.5 GHz.

I dislike having to ask the question of which is better and have a discussion about it though, had hoped for ivy to simply be an obvious (if only slight) step up.
