Sandy Bridge-E Model Numbers, Clock Speeds Surface
Here are details of the first three models of Intel's "Sandy Bridge-E" Core i7 processors in the LGA2011 package. Some of these details were made public as early as mid-April. It was then analyzed that Intel was driving two distinct lines of LGA2011 client processors: Enthusiast and Performance, and within Performance, there were BClk multiplier-unlocked six-core, and locked quad-core chips. With the new series, Intel will move to the 3000 series of processor model numbering, indicating that the new processors will be part of Intel's 3rd generation Core processors, even though they're based on the Sandy Bridge architecture.
Before we move to the model numbers, here's a quick run up of the brand extenders. "X" denotes Extreme Edition, "K" denotes "Unlocked" (BClk multipler unlocked). Leading the pack will be Core i7-3960X Extreme Edition. This six-core (6 cores, 12 threads with HTT) chip has a nominal clock speed of 3.30 GHz, Turbo Boost speed of up to 3.90 GHz, and features the full 15 MB of L3 cache present on the Sandy Bridge-E silicon. Expect this chip to have a four figure price-tag.
Next up, is the Core i7-3930K, with 6 cores, 12 threads, a nominal clock speed of 3.20 GHz, and Turbo Boost speed of 3.80 GHz; but 12 MB of L3 cache compared to 15 MB on the Extreme Edition chip. This chip features an unlocked BClk multiplier, making overclocking it possible.
The most affordable LGA2011 chip will be Core i7-3820, with 4 cores, 8 threads, nominal clock speed of 3.60 GHz, Turbo speed of 3.90 GHz, and just 10 MB of L3 cache. Unlike the other two, this one has its BClk multiplier locked. All three models feature quad-channel DDR3 memory controllers, but it is likely that the lower-end models could also have lower DRAM multiplier limits. All three chips will have other features in common, including a PCI-Express 3.0 root complex that gives out two x16 links to drive graphics.

Considering your gaming resolution(s) I'm not even going to discuss if it's worth the upgrade or not, price wise.
$500 i7 3930K 6c/12t
Use your math to figure it out
For you it is a $20 premium
For my math it is a $90 premiumAt the higher resolution the more GPU dependent the system becomes(Games)
Video work = More cores equals more power(Video,Photo)
Depending on the resolution of the work the more ram also helps(Video,Photo)
Anway, sorry to say it so bluntly, but your math regarding % sucks. 6 is 50% more than 4. OR if you prefer 4 is 33% less than 6 or also 4 is 66% of 6. You have to choose which method to use, you cannot do what you did. Using the second method (substractive) for calculating the core count and then using the other (additive) for calculating price: since 4 is 66% of 6, then 66% of $500 is, $335, so once again you'd be paying for what you get, more or less.
:(
Sorry
I am getting jumbled with other math formulas
You have to hope for other people to correct you lol
I'm hoping to be getting two 3Gb 580's one for each rig, but when I can afford to do so, I'll buy the newer 6xx series or whatever ATI are throwing out at the time (depending on performance and memory size) for the other rig which I might put in three or four cards in, depends if three will be enough to run all three screens :)
Video work I havent done in ages, so I'm not overly worried if it takes a minute or two longer in honesty :) Well most of the videos I put together will be at least 720P and as for the photo, that just depends on what my Canon 40D manages to be honest.
As i had stated lastnight. When i went from Bloomfield to Westmere the 4Mb of L3 cache bump that westmere has did nothing for performance. What i was trying to say is that i doubt the cache increase on SB-E is going to make a huge difference at all. What will make a difference is the increased memory bandwidth of quad channel memory over SB's Dual channel.
I was hoping the 6 core had 20 megs of L3. :(

They expect the same pricing as todays corresponding 1366 cpu classes, $299, $550 and $999. I hope they are wrong, i'd like an eight core cpu, but i guess there's no room until next die shrink.
I hope they can come back soon and bring a pricing war with them!!
And, just like a few others have asked, where are the unlocked 8c/16t cpus Intel? I'm not moving to SB-E until you make it happen. It's just not a worthy upgrade to those of us that already have a 6c/12t cpu.
whats the point of releasing expensive products when only a few people can buy it?
i can barely afford a $300 CPU.
i would be very happy if Intel reports their loss in revenue. if it will ever happen........
I can't afford a Bugatti Veyron, and yes, Bugatti must be making profits at 1.7m euros each and 100K euros per tire.
High end isn't meant for you, stop bitching about it and blaming it on the company! BooHoo they want to price their CPUs at the market price instead of undercutting everyone including themselves! Also note that they didn't even release anything about prices, this is all speculation!
no wonder why you act like an ignorant person. Because you are a typical bloody high end user.
