But wait, hold the press.....


Level 1 cache size ? 4 x 32 KB instruction caches
4 x 32 KB data caches
Level 2 cache size ? 4 x 256 KB
Level 3 cache size 10 MB


More CACHE is good yes?

yes it does... but it doesn't help it.... google a few reviews thumb.gif

Hmm...this interests me.

Kind of lowers the initial build cost of a X79 machine. Get this CPU and then swap in a 3930 or some other better, but more expensive, CPU when you have the budget to to do so. Though I really doubt you could really tell the difference between them out side of a benchmark for the time being and the near future anyway.

Doesn't this chip have more CACHE than the i7-2600k?? YES / NO ???

Yes, 10MB vs 8MB.

Doesn't matter though, there ain't much of a difference between the 2.
http://www.tomshardware.com/reviews/core-i7-3930k-3820-test-benchmark,3090-13.html

Only reason to go 3820 is if you plan on going IB-E, or a 3930K or something later.

Although the Core i7-3820 does enjoy its high points against Gulftown and the Sandy Bridge-based Core i7-2600K, its pricey platform, locked multiplier, and quad-channel memory requirement don’t seem to deliver any more value than a Core i7-2600K on an inexpensive Z68-based board—and that platform gets you Quick Sync support.

So I was looking at the X79 boards and they all state Quad Channel RAM. What is this witchcraft?

I think it means that they didn't hold a press conference or demo for it...just released it is all.

It's a bit cheaper than a 2600k right, but the boards for x79 are way more expensive, so I should think the 1155 platform is still cheaper in the end. And I'm unsure of the advantages of the x79 over the 1155 platform, doesn't really seem to justify the cost, especially when we know how awesome the 2600k chip can OC...I think I'll keep my money and keep waiting...

Advantages of LGA 2011:

  1. More PCIe Lanes, more native Sata Ports better memory controller (quad channel and natively supports higher frequencies) [it also has the siliconpower to take advantage of more memory bandwidth if OC'd]
  2. Larger cache and extra CPU based features like virtualisation
  3. Better OCing due to Baseclock access and lots of other things, also the boards are better quality.

EDIT: OH LAWDY, I FOWGAWT E-PEEN.


Advantages of LGA 1155 compared to Sandy Bridge E:

  1. Cheaper - you can get a fully unlocked (top of the socket) cpu for the same prices of the semi unlocked 3820 with similar "real world" performance and much higher OCability.
  2. Wider range of products available in mobo's and cpu's so prices and availability will be higher.
  3. The socket is aimed at everyone, not only enthusiasts, so a wider variety of coolers, motherboard features/sizes (by stretch cases etc) will be available. This means that it'll have a (relatively [ ie percentage wise]) better resale value to this after intel's new "enthusiast" platform is released. This also promises more updates and revisions (such as the CONFIRMED ivy bridge), while Socket 2011 has no factual update/upgrade path.

1) Who cares about more PCIe 3.0 lanes? If you can afford to fully saturate 2.0 and put a load on 3.0, you're not going to be going for a budget CPU, you're going to spend the extra money on a more powreful CPU.

2) Larger cache for this chip is meaningless, from what other people have said and shown (obviously i don't have first-hand knowledge of it) the larger cache size of this chip compared against a 2600k is meaningless.
3) Better overclocking capability than what? the 1155 platform is a beast, have you seen how many 2600k chips around here have stupid high overclocks? the 2011 platform isn't a better platform than the 1155 as far as I can tell, both seem to have very nice overclocking capabilities. And you can't tell me that the 2011 has "better" boards than 1155. There might be more higher-quality boards for the 2011 platform, but it doesn't mean that most 2011 boards are better than all 1155 boards...

So going back to my original point, I don't see anything in regards to this chip as being worth the cost. You don't get the performance/price, and if you're worried about budget you're not going to spend a ton of money on a 2011 board. Really, this chip to me is insignificant. People who want the best of the best go with the 3930 or 3960k chips, people looking to save some money but still have excellent performance will be going with the 1155 platform. I see the differences between the two platforms, I just think this chip is a waste and has zero customer base...
