i5 vs i7 (well i did search!)
its not very easy to search i5 and i7 as two letters... stupid intel...
anyway... as far as i see.. i5 and i6 at same class are not big different... right?
but someone says it...
do you agree?
anyway... please someone tells me the summary of this... thanks...
the price difference on these cpu will be mainly on the cost of the entire system. socket 1366 motherboards are more expensive, and a 3 channel memory kit is more expensive then a dual channel kit of the same ram. Also, i'm not sure about where they got that info about the ram speed... both platforms can use ddr3 up to way faster speeds than 1333... I myself use ddr3 1600 and you can use ddr3 2000 on a 1366 motherboard if you want to. you need to look at what your motherboard can take..
So the i7 860 (for exemple) on the socket 1156 should perform as well as an I7 930 on the 1366 platform, beside the fact it has less ram.
Belong to me, it's all on what you intend to use your build for and all about the budget. If you plan to SLI or CrossFireX, I'dd go with 1366... but for a basic gaming build with only one GPU (or 2 lower end GPU that won't go over PCI-e bandwidth) 1156 should do it. and 4Gb ram is plenty for a normal gaming build.
so i will grab i7 then... thank you ;]
It's all in the hyperthreading if you are compareing CPU's only. i7's have it, i5 Quad Cores don't.
yes,what are you going to use it for? email, anything or almost can do lol
check my build plan... ;p
Differences between Bloomfield (9xx chips) and Lynnfield (7-8xx chips) go a little deeper than that.
If you're looking for details, I'd suggest Intel's website. They list processor specs in lists by i7, i5 and i3, etc. Bus speed goes from 4.8 to 2.5 GT/s in i7 when dropping from Bloomfield to Lynnfield. Lynnfield and Clarkdale (i5-6xx and i3) use the same 2.5 GT/s bus speed, but the cache size drops from 8GB to 4GB -- which makes sense because Clarkdale i5 use only two cores.
That said, Hyperthreading actually does exist on Clarkdale i5 chips. All i5 chips run four threads -- Lynnfield does it with four cores, while Clarkdale does it with two cores and Hyperthreading. For that matter, i3 chips use Hyperthreading.
i7: 4 or 6 cores (8 or 12GB cache), with Hyperthreading and Turbo Boost (Bloomfield OCs better but Lynnfield has better Turbo)
i5: Turbo Boost, 2 cores (4GB) with Hyperthreading (Clarkdale, i5-6xx) or 4 cores (8GB) without HT (Lynnfield i5-7xx)
i3: 2 cores (4GB), HT, no Turbo
Pentium: 2 core (4GB), no HT, no Turbo, small caches
i5 vs i7
8-12gb cache? Wow, plenty of space!!! must be built in ram for those puppies. Slight typo, no big deal. No offence buddy. I have my fair share of Homer moments. That's right, I said HOMER moments.
Since ive personally owned an i5 750, i7 860, and an i7 920 setup I can say this much. Depending on your tasks, these setups can seem marginally different in terms of how fast it is. Gaming and day to day apps the i5 750 is overkill at stock, and they oc like crazy and the heat output isnt too bad due to lack of hyperthreading. The i7 860 wasnt much different at all in terms of speed until I ran GAITsim that require an extreme amount of cpu power, where the hyperthreading kicked in. i7 920 wasnt too much faster in terms of speed, but I did require the extra pci express lanes that the p55/h55 series lacked.(with the exception of NF200 p55 boards)
