But CPU z says its an e1 stepping. Aren't those only retail?? I though es was e0

Not really, most reviewers also got E1 stepping. Some people got chips that did not show the revision at all. but thats about it. They are also most certainly E1.
 
Core i7 3770k and Core i5 3570K are available for purchase from newegg.

Hope they come to India soon.

This is Hyper-Threading, Intel tried to implement it in earlier iterations of Intel Pentium D's and Intel Pentium 4's to combat AMD's march towards the x86 64-bit architecture. It wasn't optimised in any ways for those days and neither were applications made with HT in mind it ended up as contributing to longer pipelines and was said to be a major caveat in Intel's thought process.

Co-incidentally initial iterations of the Conroe architecture and its predecessors did not have HT, until release of Nehalem where Intel released a new more optimised format of HT.

HT doesn't help if -- ??
  • a really threaded application, like rendering operations.
  • day-to-day computing.
  • games neither benefit, nor loose if HT is supported by the CPUs.
  • Benchmark runs, may OR may-not benefit solely from a HT enabled processor.

Hope this answers your queries, Cheers!!

I didn't get this.

Well these are how I perceive HT, now I haven't used it a lot on my personal RIG [because it is AMD K10 based], but on friends competing Nehalem systems I did not notice a great advantage in the areas listed --
  • Rendering in Autodesk MAYA 2010 / 2012 and Autodesk MAYA.
  • playing a game of the class of The Witcher 2, Battlefield 3 et al.
  • day-to-day computing, word-processing and just listening to music OR watching a movie on MPC / VLC.
  • Benchmark performance varied, because he had a HT enabled processor, whilst me had a quad-core.

Hope this helps clarify the answer, Cheers!!

ohh. Hope someone else helps me understand HT.

Bikey read here, in a gaming scenario the Core i5 2400 which lacks HT comfortably runs neck-to-neck with the Intel Core i7 950.

HT has little OR no advantage, atleast strictly from the point-of-view of gaming.

Hope this clears the air, Cheers!!

Maybe no point comparing at a level where anything higher will not make a difference?

Results might also be game specific?

Okay here is is then, a modest Core i5 2400 duels it out with the top-of-the line Ivy-Bridge processor.

Being a -k marked processor, the i7 3770k easily puts the Core i5 2400 to shame, apart from that it supports HT and is a quad-core design.

Lets also compare a Core i3 2100 vis-a-vis the Core i5 2400, please note the Core i3 processor has exactly half the L3 and L2 cache memory compared to its elder cousin but shares the exact same clock speed --

Hope this helps, Cheers!!
 
Single threaded performance difference is hardly much , from the above pasted links even between the i5 and i3 sandy , same might be true of ivy . Normally for any kind of multi tasking 4 cores are enough I guess .

So for unless people who use HT , i7 might be a waste .

First I used to think the single threaded performance of i5 and i7 differ by a considerable margin , but they are pretty comparable .

So this is my personal feeling , that for most people who are not into animation or abode users who really use the HT , i7 is absolutely not worth the penny .

i5 is the sweet spot .

Also one thing to notice is that the TDP is listed as 77W instead of the rumours which speculated 95W .
