Oh so some people at Best Buy thinks it's a real core so you assume everyone else would think that too? Like the others have said real CPU cores takes more space and more power while HT only requires a little more power and a little more space. And not to mention HT is one of the reasons why i7s are so effective against Thubans in highly threaded benches.Quote:

If I had more cores I could do even more work, be it running more threads from a small number of programs or running more single-threaded programs simultaneously.Quote:

Your last sentence is key there. The vast majority of apps are single threaded bound but end users will like been able to run multiple apps at once without them affecting each other, multi core is defenitly useful for that.
solus what browser? IE eg. has multiple processes but it is not multiple threaded. Firefox and opera are also both not multi threaded. Flash is not multi threaded.
Isn't google chrome multithreaded?
Each browser window, is it's own thread though... right? :dog:Quote:

Separate threads for each tab would help on dual core atom.Quote:

You're right, so why don't we compare Intel's 6 real cores plus 6 virtual cores to AMD's 6 real cores? :DQuote:

Whaaat?? That doesn't make any sense at all, why would anyone say that. Websites make those comparisons daily in their reviews. Especially the intel-centric sites like anandtech, as long as it works in intels favor. some might have a disclaimer of a couple obscure words in brackets aluding to some aspect of the fact, but the graphs are shown, and the data is presented. So the comparisons are made routinely. /Quote:

* hyperthreading is a trademark of intel corporation not to be confused with SMT
why you guys are even comparing it to the 9xx seriers... the 8xx seriers has the same performace, and consumes less (platform wise) and is even the same price range as thuban....
I myself am not a fan of the comparison, and I think it's perfectly valid to compare the power consumption of the those different processors.Quote:

i agree.maximumpc did a quick review and the i7-800 series is very competitive vs the 1090T.Quote:

I know the stupidest thing I have ever done with chrome is before going on a vacation I preloaded 100 youtube videos of a tv series on my laptop so I wasn't bored during the drive. Yea not a good idea to load 100 Chrome tabs ever.
Yup, no tab overflow and the fact that Chrome uses quite a bit of memory. But that latter part is pretty much a result of each tab being its own process.Quote:

Saw that review too, but how can they say it's a better value on platform cost? Can't use DDR2 or cheaper mobos with the i7-875k. Anyways I'll stick back to the topic.Quote:

silicon available earlier then predicted??? :D would be fun
Except when it comes to the benchmarks there would be complaints of DDR3 vs. DDR2. Anyway you slice the pie, there would be complaints.Quote:

or it will only use 1 core.
Some high res flash videos used to saturate my core2duo, I would have frame stuttering whilst my 2nd core was idle and available but first core at 100%. Some web pages also capable of saturating cpu as content heavy again, not stressing entire cpu just one core.
So to be clear I mean one tab in a browser will only fully utilise one core at a time.
my i5 handles things much better as heavy pages cause it to trigger turbo mode.
task manager doesnt accurately measure utilization, especially with HT. a performance profiler would tell you whats truly going on during runtime. i.e. if an app has 4 threads 50% w/HT is the same performance as 100% w/o HT on my i7. i have observed and measured this before.
How do you measure "total throughput" ?Quote:

Should we think of it as both int & fp independently? Their average? Sum? Minimum? Maximum?
operations per second, possibly in some abstraction.Quote:

no. they are just data types that should be completely transparent to the user. the kinds of benches you run should reflect what applications you use so you will already choose the best processor.Quote:
