Keep your Sandy Bridge!

[xVeinx]

Intel cuts IB's price before launching them, if true then its an admission of something(more reason to keep your SB?).

Not really. They will be better than anything else available, and the inability to overclock to 5 Ghz except on good water has little bearing to most of the market. They set the prices to what they think the market will pay.

This seems exact. My tipical 24/7 oc is around 4.2 to 4.4ghz but i like to bench sometime and being stuck at 4.6-4.8ghz with a high end air is bad VS a 2500/2600K that can reach 5ghz on air. Even Water dont seems to really help with IB, you need exotic cooling to get more mhz.

Wait wait wait, frequency isn't everything. If it was we'd all be on Cedar Mill and Bulldozer. 4.55 GHz on IB = 5.00 GHz on SB in 3DMark11 with Lucid OFF. 2D doesn't show the gains as well as 3D does.

oh yes but everybody at least wait for 5.0 ghz easily ivy clocks that make sounds like 5.5 sandy..that 's dissapointment!

Quick question here........

1.) Hasn't anyone besides the OBR tested these new Ivy's?.......maybe he received a lemon chip?

Fugger came in here on the first page and said his Ivy destroyed his sandy's. Besides these two guys......isn't there anyone else around that can confirm this?

Fwiw....I'm holding off to build my first i7 build until the Ivy's have been released to see what the performance and price is going to be. I may just stick with a 2500K - 2600K......prices have been great as of late anyways.


For a dumb noob like myself....the OP bummed me out with that report. I was hoping to see something along the lines of it completely smashing the hell out of a 2700K.

I don't have special knowledge or early access to the processors, but Anand, Tweaktown, and others here on the board seem to be telling a fairly consistent story: performance is good, better than SB, though they run hotter. Waiting isn't a bad idea, but you may just decide that SB is better for what you want. Frankly, you're not likely to go wrong with either processor. If you bench, Ivy is the way to go. If you are more into gaming, it may be a toss-up depending on how high you can clock your particular SB. If you live in a warmer climate, you may have a harder time maintaining clocks year round as well, so all that has to be factored in. We should know soon how things will shake out.

Well would be nice IF Charles said that the 24/7 speeds of his Ivy crushed his SB... but I think he was refering more about extreme cooled OCs and not air or water operations... Or he has received a lemon IB CPU handpicked by Francois :p

[Buckeye]

IMO the myth of running a SB @ 5.0ghz for gaming is a really not that big a deal. 4.6ghz - 4.8ghz will work just as well for most stuff I guess.
I am running a 990x @ 4.6 and I have setup machines with 2500K or 2600K/2700K @ 5.0ghz and I really don't see any difference. Maybe if you are running large screens I don't know. My screen rez is 1920x1200.

I see the new motherboards as more of an impovement and a graphics card upgrade.

Single threaded performance is more important imo. I don't know maybe depends on game really.

Yes, others have tested. FUGGER is indeed correct, IPC in 3D is killing Sandy Bridge. 2600K @ 5 GHz HT disabled 3DMark11 = 7991 3DMarks, 3570K @ 4.55 GHz = 8004 3DMarks. A 450 MHz deficiency and the same score (it's well within margin of error). Sorry I'm not going to show pictures yet, but you're welcome to wait and see for yourself. If you can reach 4.7 GHz on air, you'll be up there with a 5.2 GHz 2600K - a speed that not many (if any) can run 24/7. In that respect IB is indeed a lot better than SB. FUGGER also didn't give specifics, he could be talking about extreme overclocking with 6.5 GHz or more in which case SB can't hold a candle to IB as not only IPC is up slightly but clock speeds are in a different league.

If you have SB right now running upwards of 4.5 GHz, don't upgrade unless you need the bragging rights. If you're on anything pre-SB, wait for IB.

Honestly though, there's no need to take my word for it. The chips will be out soon and then you can see for yourself what IB can do. Since Feb I've been saying that clock speeds are going to be lower for 24/7, overall performance is going to be better and overclocking is going to be unholy - watch and see

[Leeghoofd]

There's more to life then 3DMARK11 and 3D. Plus as Buckeye said for gaming you don't even need a 4.5Ghz SB... le'ts talk about heat and consumption within a few weeks...

[[XC] Oj101]

2D performance is up a bit, as I said not enough to warrant an upgrade from SB especially considering it doesn't clock as high. /shrug

[Buckeye]

As I can only go by what I have been reading here and other places as I have no hands on with Ivy at all I don't see this new chip as being a bad thing.

We had QX9650, 920 and a whole host of other CPU's that had limits on Air Cooling/Water Cooling but could be pushed really hard on extreme cooling which is what this forum is all about. Thats great IMO

SB came out that really rocked on Air Cooling/Water Cooling but did not get any boost from extreme cooling really, plus hard multi locked chips. That was Bad for this forum unless you happened to find a really cherry CPU.

SB-E came out that gave us outstanding performance on Air/Water and could even use Extreme Cooling. Thats Great for this forum !

Now Ivy is coming out that appears to give great performance at lower clocks and stand back now... appears to Rock on Extreme. This forum now has a reason to pull out its phase/cascades/LN2 again, Yeah !

If you allready have a nice SB setup then yeah no real need to upgrade except maybe motherboard & gpu's. But new setups might as well go Ivy if the price is right. But then again there are plenty of people still using water cooled 920's and those machine's still perform well.

And even with dual cpu setups like SR-X at stock or slight BCLK increase using less power and heat which should give same performance as SR-2 and Westmeres highly overclocked.

It sounds to me like we are getting CPU's that will bring back the Extreme to this forum and we all should be happy

[AMD_Freak]

good to hear with so many rumors going around.

[Charles Wirth]

-40c (single stage) will be enough to topple the best.
-100c (cascade) and you will see numbers worthy of showing off.
-180c upper 6's
> -200c lower 7's

Anything warmer is purely speculation.

really?

[Leeghoofd]

really?

I'll correct myself Steven : There's more to life then 3Dmark11, 3D and Gigabyte :p
For gaming there's no need for 4.5Ghz CPUs unless you got some super duper extreme setup. If I read correctly you got a cherry IB sample, beating your 5.2 SB in raw clocks

The big misconcept in this thread is : people inquire for daily OC's or E-peen( they still want them magical 5ghz ). Not our Extreme OC's that got almost nothing to do with 24/7 stability If a legend as Charles drops in and says IB crushes his SB, it can be completely misinterpreted for the daily clockers, which is what I rather would avoid.

Buckeye's post sums it up quite nicely

[dejo]

I dont think single thread efficiency is up very much if any at all over SB. From the screens that I have seen, you also have to figure in the clock difference from an 3770k vs 2600k. I think for most that SB will be every bit as nice as Ivy, unless extreme cooling is used- then there seems to be a complete reversal of fortunes.

You are wrong the gain a nice amount in clock per clock vs SB.

[clubber_lang]

Thanks [XC]oj101 and xVeinx for the info! Been wanting to build a new rig for a couple years now....and just keep putting it off. This time....I'm going to wait and see what the Ivy cpu's will do and what thier prices are going to be like.....then make a decision on either and Ivy or SB and get the ball rolling.

which would you pick out of a 3770k or a 3820 please ? I'm upgrading from a Q6600 and I'm guessing that build price for mobo/cpu/ram is about the same for a 3820 and mid-range X79 motherboard or a 3770k and mid-range Z77 - as although the X79 motherboards are slightly more expensive - I'm guessing the 3820 is/will be around $70 or so cheaper than the 3770k ?

many thanks - just gaming and the odd bit of video encoding

also - as a footnote- the Sandy prices have started reducing in the UK - the 2700k can now be got for 5 dollars or so more than the 3820 - its come down quite a bit over the last week. I'm thinking that in reality another option would be 2700k + Z77 - the 2700k is not much more than the rumoured price of the 3550k and a lot less than the 3770k. 2700k aren't exactly shabby overclockers ...

That's excellant news to my ears.

I'm not a fan of the Core i7-3820. It has a locked multiplier which means you won't be doing much overclocking, and isn't very different from a 2600K. IPC is about the same, but you'll be paying more for the SB-E platform.

FUGGER you've got a nice chip there That'll be sub 5m spi32m and VERY low 5s spi1m Now combine that with some 3000+ MHz 6-11-7 loving please (if you know what I mean )

Same thoughts as Oj101 : Go with a V Gene, 16Gb of ram and a 3770K , don't even think about X79... too costly and most 3820's top around 4.8Ghz on air...

[Dumo]

Imo, Mostly if not all Ivy can do 6Ghz+ ln2'ed, but not all can scale up 2800+ mem (on air)...It probly needs binning
