Why do you purchase i5 and i7?

[WaterFlex]

I can`t understand you at all.
I5. 2-way ram.
i7. 3 way ram. Performs a little better than i5.

Why can`t u wait a half of year and buy i9 ??? The best of the best?

[[XC] Hicks121]

I have been scratchn my head on this one too.

[Bojamijams]

ugh .. i7 is not 3 way ram.. i7 860 and 870 are still P55... terminology is way off

i9 won't do anything for years.. we're just barely putting all 4 cores to use and HT is just beggining to trickle in, regardless, there is nothing that needs more then 8 threads

So x58 is and was overkill for most things.. p55 is just as fast if not faster in games, for less heat, less money and better o/cing ability.

If you're still on S775 as I am, then P55 makes more sense then x58.

Oh and fyi.. since P55 has better memory performance (excess of 20k easily in everest) its quite up there in terms of bandwidth verses any x58 thats still at DDR-1333 or 1600... not to mention that most things still don't benefit from the 3rd memory channel

[kerberos]

I think X58 is better for SLI, 2*16x slots vs. 2*8x on P55. But I like the enhanced turbo mode and optimized temps on the P55 systems. Gulftown (i9) will probably be very expensive.

[Hondacity]

its a cheap upgrade for those running q6xxx and e8xxx and some e7xxx

i for sure won't buy these...the i870 is 5xx$ LOL

[Splave]

I have both, figure that :banana::banana::banana::banana: out ;)

Not everyone is a strict gamer, I have them both because I enjoy tinkering with them. Understanding minor nuances etc. This is xtremesystems isnt it?

so your question why not wait?
why not wait for i10 or i20 or i60, because who wants to wait? Doesnt work that way with comps, you pay to play today. Sitting on your hands is useless unless you enjoy your own stink

I can`t understand you at all.
I5. 2-way ram.
i7. 3 way ram. Performs a little better than i5.

Why can`t u wait a half of year and buy i9 ??? The best of the best?

1. I prefer 2-way RAM cuz of the overclockability ratio advantage
2. 3-way ram => more likely to get a RAM stick failure => RMA (require all sticks to be sent in) => PITA
3. i9 ridiculously fast and ridiculously expensive for the 5% of apps/usage scenarios where it actually can show a huge benefit in the near future with the 2 extra cores (crunching especially which isn't my cup of power bill/tea).

And let's extend the list what personally applies for at least me:

4. Never intend to use SLI/CF with whatever card at whatever price with whatever power consumption.
5. P55 motherboard design overall is damn nice. I've never had the pleasure of picking a board of so many nice choices. For example Gigabyte's P55 clearly beat the X58 in this category in design/feature offering IMO. BioStar offers better OC software support. MSI finally got around to design a decent mobo in ages and even ASRock doesn't look too shabby! etc. I'm particularly interested in Gigabyte UD5 at 164 EUR, a true highend board for just above the typical midrange price level, or more like just between mid and high level price segment.
6. No updates after Gulftown in near future (Clarksdale, 2 cores...) which was already a no-no option, might as well grab a mature current gen tech especially as my micron DDR2 RAMs are dying and NEED an upgrade now and can't wait like 10 months+ for next gen.
7. Perfect replacement for a Socket 775 P35/P45 mobo and poor OC old E8xxx dual core stepping C0 CPU from Penryn launch.
8. If all or most of the above applies, the performance/cost ratio is a benefit as well, although relatively small still, but a win is always a win.

Hope that makes sense, going most likely for a i7-860 & Gigabyte UD5 which will be kept for a long time, probably along the lines until successor of initial launching true next gen will arrive unless there will be a relatively cheap/nice overclocking die shrinked S1156 option (compare Conroe -> Penryn).

love computers, always funny to sit down with new hardware:up:

[Eldonko]

Couldnt have said it better. :up:

[afireinside]

Not everyone wants to wait, and not everyone waits 1+ year between upgrades. I'm sure a lot of the people here are buying i5/i7 now and will buy i9 in the future as well.

[ajaidev]

Well because i9 is not the best of the best, when i9 does get out in q2 2010 sandy bridge will be in route by q1 2011 and frankly AVX alone is more exciting than all the enhancements westmere has to offer.

But this does not mean i would not try and go for the i9/AMDs six core, if i do get a x58+i7/AM3+PhII instead of the P55+i5. The sad part of the whole thing is Sandy Bridge is suppose to have a new socket 1155, that means x58 goes bye bye in 2011 and same is the fate of AM3 "most likely"

[oggie]

Its nice to test yourself how the technology is improving ;)

[scottsche]

People who are on Pentium IV's?

The cost is a factor, MoBo's are a little cheaper and i5 is same price as good 775 processors.

But I don't understand i7 860 for over $300, though. That makes no sense. And i7 870 for same price as i7 950? Double no sense.

I'll wait for 32nm in the winter/spring.

+1, if you wait then you'll wait forever. I can get i7 + X58 for just a bit more than i5 + P55 so I don't see why not. And some said earlier, X58 is good for multi GPU due to the whole PCI-E dual x16 rather than P55. In term of overclocking, I haven't seen how i5 or i7 860 or 870 better than i7 920, 950 in any way, maybe just a small margin but not significant or a whole lot as most people can squeeze their 920 to 4.0Ghz easiy. One more reason? I'm safe down the road when Core i9 release. :cool: Last but not least, welcome to XS forum.

[Earzz]

Im not upgrading towards anything, my rig can still handle everything i throw at it.
Still really wondering what these new CPU's/Chipsets really ad, ok they are great for benching and folding but is it really faster in normal use and gaming?
Im gonna wait for one more year and see how my PC will perform, then and then ill consider upgrading.

"Not everyone is a strict gamer, I have them both because I enjoy tinkering with them. Understanding minor nuances etc. This is xtremesystems isnt it?"

yes its extremesystems.but after its clocked up enjoy it by gaming vs finding whats wrong with them(minor nuances).its like smashing your face into a wall,yes u will get a headache(rma time??).everything has a limit.u will go crazy trying to push your hardware every single day for minimal increase compared to the next guy.pick a game being thats what these were pcs are built for and enjoy it...i dunno...no more real gamers out there anymore.mabye when my reflexes are snail speed i will get into benching when i can barely move my arms,fingers.will never uderstand why guys buy my same $500 Gaming video card to run loops of 3dmark all day....cool for like a hour tops...now if there were real money in it,diff story.

man u cant pass up on ati 4870x2(so0n 5870x2!) or a gtx 295(so0n gtx 300!).plus these cards are using the same space or less then 2 cards.u can also upgrade to quad sli -quad xfire easily,amazing cooling options(air or water) + twice the gaming/crunching power and only use 1 slot...win/win/win

these are thee days were we have AMAZING firepower in single slot solutions..were lucky.we used to have the dual pcb crap designs for years.

did u see this thread comparing intel cpus?? i will not buy intel until its a 32nm(futureproofing),but there is a good improvement on this multithreaded game benchmark shown below no doubt.

mabye in the next year or 2 games,but not now.and if so..by a small amount.good point earz.benching is cool for like 5 min...gaming is were its important.

nice setup u got btw earz...that runs games good,i know it does.

dam right..32nm upgrade can be justified.gonna be a really long time before they go smaller then 32nm...futureproofing at its best there.32nm ftw in 2010!!

the only issue i can see upgrading to a 32nm part is sandy bridge would be so close and then blow those old nehalem chips away.

"Clarkdale/Arrandale have 32nm CPUs but their on-package GPUs are still built on Intel’s 45nm process; these are the GPUs that were supposed to be used for Havendale!

It won’t be until 2010 with Sandy Bridge that we see a 32nm CPU and 32nm GPU on the same package."

"At the very high end, Core i7 users have little reason to worry. While Intel is expected to bump i7 up to 3.33GHz in the near future, nothing below i7 looks threatening in 2009. Moving into 2010, the 6-core 32nm i7 successor should be extremely powerful. Intel’s strategy with LGA-1366 makes a lot of sense: if you want more cores, this is the platform you’re going to have to be on.

Now although I said that nothing will threaten Core i7 this year, you may be able to get i7-like performance out of Lynnfield in the second half. A quad-core Lynnfield running near 3GHz, should offer much of the performance of an i7 with a lower platform cost. Remember back to our original i7 review; we didn’t find a big performance benefit from three channels of DDR3 versus two."

No I haven't seen it, pls give me the link so I can see how they're OC better than the 920.

Because Core i7 920 is the best bang for buck? Plus nearly all go beyond 4GHz easily. 4 cores, 8 threads, 3-channel, 4GHz+ clocks. I don't think i'll be buying new CPU for next 5 years minimum lol. I'll rather change gfx cards instead if needed.

i never siad they clock better,slight performance boost in that multithreaded game...


Core i7-860 Tested: Faster than Core i7-920 ----- very slim tho....

"According to the test run by the Turkish website Donanimhaber, Core i7-860 outperforms Core i7-920 in almost all the benchmarks, especially winning a great vitory in power consumption section.The Core i7-860 has a clock speed of 2.8GHz and a TDP of 95W, while Core i7-920 operates at 2.66GHz with a TDP of 130W."

see im not sure if this is fair..the 920 is at 2.6 and the 860 is at 2.8 .....i dunno... 32nm only here.

[zanzabar]

the p55 is faster than the x58 in almost everything with 2 or less gpus, 16x16 pci-e2 has almost no advantage over 8x8 so its not like that matters and there is lower lattency so its got an advantage in latency and little to no loss in usable IO

[koksy]

I'm sorry, is this the wrong forum? Nope, still XTREME SYSTEMS. We get the newest technology as soon as it's out. We test it to it's limits, and then push it even further.
Why not wait for i9? Because i9 will run on socket 1366 just like i7, so we can just upgrade when they release it.

[WaterFlex]

I just have not got a lot of money to afford e8400-->i5-->i7-->i9 upgrade. So, my question borned coz of it :)

I can`t belive rig on P55+2way ram+i5 (i7 860 and i7 870 also) runs faster X58 with 3way ram!

I know. Intel made this step to earn a lot of money. They gave us i7 and then i5. They also helped RAM manufacters to earn a lot of money by doing so, making you to buy more expensive 3 stick kits.
Thats it.

[zanzabar]

the 1366 and 1156 are different, the 1366 has an on cpu memory controller but from what i understand the 1156 has a more intergrated memory controller and lower latency, then the 1366 has the x58 for pci-e (32 lanes) and ich10r for drive IO/pci but the 1156 has the cpu on die pci-e controller (only 16x) but being on cpu it runs lower latency.

once we get the 32nm 1366 i would expect the memory controller improvements that are on the 1156 so then i would expect it to take the lead back, and clock better


and dont forget that the parts are designed for jdec ram, and jdec ddr3 is 1066 cas9/7 and 1333 cas9 but the normal minimum here is 1600mhz cas8 and most people have ram well faster than that

Thats it.

If you dont have the money just wait ;), ask yourself that you really need a faster CPU.
I bet you dont have any problems running anything on your rig, ok its cool if you have a i5 or i7 but do you really need it?
Upgrade you graphics card and buy some SSD's and you will have a future-proof rig again for a year or so.

[fatguy1992]

The reason why I went i7 is so I could help my hwbot points/ranking's up :) I don't game or do anything that needs a fast PC apart from benching.

[messerchmidt]

i got the i7 920 because there was no i5s (or 1156s i7s) available when I bought my stuff. Otherwise I would go i5 on 1156 (or maybe an i7 860, I like HT...).

right now the 1366 platform makes sense if you run multiple videocards and/or plan on getting an 6 core i9 when they become available. otherwise i5/i7 on p55...
