RadioActive Posted October 25, 2009 Share Posted October 25, 2009 These benchmarks doesn't tell the whole story but still it should give a pretty good idea, enjoy 8) Note: I picked the 920 because it has the same clock/cache as the 750.Although the i5 isn't meant to compete with the i7 the results are pretty amazing especially considering the price difference, don't you think? :coolwink: Link to comment Share on other sites More sharing options...
kartikjos Posted October 25, 2009 Share Posted October 25, 2009 Yeah, I'm surprised how similar they are.Over here the price difference isn't that great, but seeing as I use laptops quite a bit, the power savings are significant.Thanks for sharing Link to comment Share on other sites More sharing options...
Toshiro Posted October 25, 2009 Share Posted October 25, 2009 Almost 100€ difference here in Holland.. And they perform almost identical.. lolThnx for the post :) Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted October 25, 2009 Administrator Share Posted October 25, 2009 Well, that makes me think more about i5.Can someone tell me what exactly is a core speed? i5 is ahead than i7 in core speed. :think:And what does hyper-threading really means?

I believe i5 is much better (in terms of cost-to-benefit). Link to comment Share on other sites More sharing options...
SokraT Posted October 25, 2009 Share Posted October 25, 2009 hyper-threading, if i remember right , is a feature in CPUs that enable it to emulate multiple virtual PCs to the applications. Link to comment Share on other sites More sharing options...
i-con Posted October 25, 2009 Share Posted October 25, 2009 Going for i5. It's cheaper and delivers almost the same performance as i7. Link to comment Share on other sites More sharing options...

RadioActive Posted October 25, 2009 Author Share Posted October 25, 2009 Thanx for the info. Well I still have 4 months to decide which one to get. :DSame here, I might upgrade within 4~6 months, and so far i5 seems the only real choice. Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted October 25, 2009 Administrator Share Posted October 25, 2009 Well here is the price here - Rs. 16,045 for i7.vsRs. 10,925 for i5.BTW can a normal DDR3 RAM work with any of the above processors? Or only specified RAM work here? :unsure: Link to comment Share on other sites More sharing options...

Or only specified RAM work here? :unsure:ummm...yeah, there only specific RAM that would work with those processors and guess what? it's called DDR3 :POk, PEOPLE LISTEN UP, something most tend to to forget, when you compare i7 vs i5 you MUST keep in mind the TOTAL cost of the system (CPU + MoBo + RAM) not just the price of the CPU, because the CPU vs CPU in price might not be THAT much but when you compare System vs. System only then you'll feel the difference :bruce: Link to comment Share on other sites More sharing options...
Administrator DKT27 Posted October 25, 2009 Administrator Share Posted October 25, 2009 Well to be honest, I have not found a mobo that supports i5 to look for it's price. Can you tell what is the price for a i5 mobo there in US$? Link to comment Share on other sites More sharing options...

Can you tell what is the price for a i5 mobo there in US$?Well, I believe the average price of a P55 (LGA 1156) MoBo is around 150$ or so. and don't forget that i5 is dual-channel unline i7 which is triple-channel, which means in i5 you'll only need 2 RAM chips instead of 3.

Administrator DKT27 Posted October 25, 2009 Administrator Share Posted October 25, 2009 Well that $150 makes me feel it's very much affordable to me, the whole PC.What chips are you talkin about? You mean the chips that are on the RAM? Link to comment Share on other sites More sharing options...
WaKa WaKa Posted October 25, 2009 Share Posted October 25, 2009 If you are an overclocker and you buy a P55 mobo, check the socket.Sockets made by Foxconn = fail :fear: http://www.anandtech.com/mb/showdoc.aspx?i=3661 Link to comment Share on other sites More sharing options...

Infinite_Vision Posted November 19, 2009 Share Posted November 19, 2009 Lohengrin,I am thinking about building my own computer and after reading your article, I think I will go with the i5 even though it is dual-channel than Tri-channel Ram. This will be my first attempt at building a barebone computer because I want to create a mini studio in my room. I'm looking to build now because we will get a tax credit for buying a new computer this year. :) Link to comment Share on other sites More sharing options...

karachidude Posted November 19, 2009 Share Posted November 19, 2009 triple channel is faster than dual chanell B),i will buy an i5 ;) Link to comment Share on other sites More sharing options...
Night Owl Posted November 19, 2009 Share Posted November 19, 2009 Wow, the i5 and the i7 shown here are so close in performance. Yet the i5 gives you 28% in power savings — great for notebook users. Link to comment Share on other sites More sharing options...
RadioActive Posted November 23, 2009 Author Share Posted November 23, 2009 Well I'm still confused. What is meant by dual-channel than Tri-channel RAM? :unsure:triple channel is faster than dual chanell B),i will buy an i5 ;)After all these tests you need to ask yourself: What the heck is that triple channel mode useful for anyway, when it is obvious that is doesn’t provide performance boost that is expected? Maybe in the future and with some new versions of memory controllers, triple channel mode will provide better performances so transition to this platform will make more sense. Until that moment triple channel mode will be just another nice sticker on LGA 1366 motherboards and memory packages. Of course memory manufacturers already have triple channel DDR3 kits that are intended to be used on Intel Core i7 platform. Since these are triple channel kits they have three DDR3 modules with total capacity of 3GB or 6GB. Since prices for DDR3 memory are still pretty high it is obvious who will profit the most from this situation where (uninformed) users will go for triple channel kits with intention to use up potentials of their new platform.Source: http://www.insidehw.com/Reviews/Memory/Intel-Core-i7-Dual-Channel-vs.-Triple-Channel-Memory-Mode.html Link to comment Share on other sites More sharing options...
Patrick Posted November 23, 2009 Share Posted November 23, 2009 wait for AMD to come with 8cpu or 12cpu qaud and sse5.........Bulldozer is 2011. By that time Intel might have a new one, unless AMD Fusion or whatever new chip they have beats it. Link to comment Share on other sites More sharing options...
