Core i7-3820 Sandy Bridge-E Starts Selling in Japan

Intel's most affordable processor in the LGA2011 package, the Core i7-3820, surfaced on Japanese stores in the Akihabara electronics shopping district of Tokyo. It is priced around 25,000 JPY (US $322). The retail box of this chip, carrying the S-Spec code "SR0LD", appears to be as big as those of the Core i7-3930K and Core i7-3960X Extreme Edition, its shape indicates that it lacks a bundled cooling solution, and so users should still rely on compatible third-party coolers, or use Intel's RTS2011LC, purchased separately.

The Core i7-3820 is a quad-core part carved out of the Sandy Bridge-E silicon. It has four cores, and eight logical CPUs enabled with HyperThreading Technology. The chip is clocked at 3.60 GHz. Caches include 256 KB L2 per core, and 10 MB shared L3. The chip retains the quad-channel DDR3 IMC present on the more expensive six-core parts. It is also said to be "limited unlocked", meaning it allows multiplier-assisted overclocking to a certain limit. The Core i7-3820 is not officially launched, though it should be unofficially supported by most socket LGA2011 motherboards based on the X79 chipset.

I'd rather pay half the price for a motherboard so I vote for the 2700k. I'm not into the higher latency and unneeded pci lanes. With that said you couldn't go wrong with either.

It's not that different, I find. The sad part is that the boost given by the extra cores for daily use by X79/SKT2011 is kinda a worthwhile offset for some users, but this chip lacks that advantage.

Not that that will stop me from getting one.:laugh:

It seems to me that this is a little bit more expensive than going 2700K. The main difference being the price in boards. You can start with a very cheap SB board, and go all the way to almost as expensive as the top end SB-E boards.

It would seem to me that you should choose the board that you're happy with, between SB-E and SB and if you don't feel you're paying over the odds for a SB-E board then the 3820 is the one to go for.

Having said that I think in the vast majority of cases the 2700K wins it.

Why? Because the features on motherboards now, in my opinion, are not worth it.

Extra PCI-E lanes are only useful for the minority that run multiple graphics cards, and even then the extra lanes don't deliver cost effective performance - although if you're going for high end then you're already happy to sacrifice bang for buck.

The build in sound I've never found to be as good as a proper discrete card. Which makes me say who is going to drop hundreds on a motherboard (and likely change it in 2-3 years tops) but not prepared to drop money on a decent sound card?

USB slots... needed? Really? Isn't a couple of USB 3 ports enough? The USB 2 ports can be expanded with dirt cheap hubs.

Overclocking? First of all the higher end boards provide more stable power, usually, but other than that there's not a great deal of difference, you're going to maybe get 100 mhz more, or 200 tops... is that worth dropping an extra couple of hundred on? And it seems that board designers across the market have one basic design and they add/remove built in features to it, that would seem to indicate that overclocking performance isn't going to be greatly different across the ranges.

Memory advantages? Really? Anyone who's looked into it knows that with a discrete graphics card memory speeds don't make much of a difference at all... certainly it's the worst area to spend extra money on a build.

So.. if you can justify a SB-E motherboard then go for it.. but I seem to be seeing right through the high end motherboards so I think the 2700K is the right one for now.

Personally I'm holding off to Ivy Bridge and I'll possibly grab the top end CPU there and a dirt cheap cougar point board to pair it up with. I now suspect I'll have no regrets.

To me, the 3820 is obviously better for ME. But what bothers me is that Ivy Bridge will probably be better than the 3820 and at a lower price. An i7 920 was top dog for a super long time, even SB was barely any better, so the i7 920 was beat only now, when the 3820 came out, and still, not by a big margin. Sadly, the 3820 isn't really the next i7 920 at all. i7 920 lasted over 3 years, the 3820 will last less than 3 months

Intel is obviously looking to make more money by having their top dog change as fast as possible. I'm not counting the hexacores because of their price of course

Well, they may be aiming to do that n-ster, but I don't see them making a great success of it. My requirements are different to yours by the looks of things, however I don't think either of us would relish paying for a -E type CPU when within 6 months the non-E CPU comes out and equals it, broadly speaking, in performance, on a cheaper platform for a much cheaper price.

Perhaps the SB-E will have more longevity for productivity type stuff - rendering etc. But for general purpose use you could justify the X58 platform in a pinch, but if the -E is beaten by the next release of the standard platform then the -E is going to only go where money is of little object.
