How do vPro, VT-d, Trust Execution, and TSX Help me? 4770 vs 4770K

I'm leaning towards the non-K version, but do these features help in parallels or fusion. What do they do and what situations would they be useful to have in?
 
I asked myself the same thing, I tried to read some articles but I couldn't convert that explanations to daily use situation.
 
While I am not qualified to answer, I take an educated guess and say that these have something to do with visualization. Thats all I got.
 
TSX from what I have read could end up giving you 40% increase in performance in software that has been coded for it!!! down the road.

all the virtualization stuff I can't comment on, but if you do run multiple OSes and such my guess is it will be worth it to you to get a non K version, as the K only allows Overclocking and IMO is worthless on Haswell as it runs so dam hot... I would rather have features and extensions that help speed up my code and not a few hundred extra Mhz that don't translate into much of a speed gain IMO... now if the Overclock would help say 20% then yeah be a harder decision to make...

TSX is not worth worrying about for at least a couple of years. If you want to OC, go ahead and get the K. VT-D is more security related.

It depends extremely alot of the code. I doubt TSX will bring much for most of the typical desktop loads. As Intel also writes:

Intel said:
Intel TSX targets a certain class of shared-memory multi-threaded applications; specifically multi-threaded applications that actively share data. Intel TSX is about allowing programs to achieve fine-grain lock performance without requiring the complexity of reasoning about fine-grain locking.

However, if there is high data contention the algorithm would need to change in order to have an opportunity for high scalability. There are no magic bullets that can solve the problem, since true high data contention implies that the algorithm is effectively serialized.

I definitely agree. It might be even more than 2 years given that Intel was stupid enough to fuse off TSX from many of its chips so that many developers won't bother even investigating it. I bought 4770K, I'll let others investigate the benefits of TSX.
 
Forget TSX ... just compare it to the situation of AVX ... AVX is in the market since SandyBridge and how many applications are coded for it?

Haven't all the finest devs migrated to the mobile market? Who cares about desktop, really.

I think, I will keep my Conroe box for another year. The new extensions seem like a joke to me. I am fine with SSE2/SSE3 for now.
