Hello, I am wondering if you upgrade the cpu from 2500k to 2700k make any difference in fsx?

Thanks

Hello

Not really, until you push the 2700K past 4.6Ghz and upwards

Makes no difference specifically for FSX because it does not use HyperThreading. Other wise they are the same chip and both equally capable of overclocking. I have my 2500k working very comfortably at 4.9 GHz. so save your money and buy the 2500k

NickN said there is a noticable difference in performance with the 2600K/2700K because of the 2MB extra cash. I can't find that thread now but it was on simforums. Better overclocking capabilities will also work. I can't judge myself, but according to NickN it's slightly better clock-for-clock.

What I would do, is wait until Q1 2013 and upgrade to Z87 + Intel Haswell. Not sure if it'll overclock or perform well, but if it does it should be a noticable difference from the 2500K.

 

EDIT: found it: http://www.simforums.com/forums/nickn-i5-2500k-or-i7-2600k-solved_topic38910.html

Scroll down until NickN's post and he says not to believe the nonsense about extra cache not being beneficial for FSX. The majority of the people might tell extra cache is not beneficial, but many people just accompany other's statements without even knowing what they say or without having tested it.

You would be wasting your money

so save your money and buy the 2500k

 

He already has it: he thinks about upgrading. ^_^

I am sure NickN is right but... how much performance gain will you actually see due to cache only...? Imho those cache differences may give nice results in benchmarks, but I wonder how much fps you will gain in FSX. The same goes for the 2500 vs the 2700. Yes, you may get better performance but how much? Probably a bit more then only a cache difference would give you but still, If you are getting 25 fps now and an CPU upgrade would give you a whopping 10% gain, that would be 2,5 fps extra... I would keep the 2500K and spend the money saved (which wouldn't be the price difference but the total price of the CPU, I suppose) on nice FSX addons. ^_^

 

People often think a faster CPU will give you something like twice the performance: that isn't so. Also because when you DO get a faster CPU and better performance, you are likely to up the setting a few notches (human nature...) and you end up with the same performance (though nicer graphics, if you look very closely).

If there were two systems side by side running exactly the same FSX install but one with the 2500 and the other with the 2700 I wonder how many could see that the 2700 was running more smoothly or whether they would appear to perform the same

The 2700k have 3 major plus to a 2500k, much stronger memcontroller clocks 300mhz higer and the extra cash.

Its difference 1-2fps in FSMark11 think its bigger difference going from a2700k to a 3770k but that is not a bigstep either.

How the "extra cash" is a plus when the 2500K is cheaper?

Stock frequencies shouldn't count either considering that if you pick a K series it's because you gonna OC it.

He's talking about the cache.

 

lol ok

My Bad ENG, Dont speek about stock Freq , a medium 2700K clock 300-400mhz higher than a medium 2500K,

2500k @4.8-5.1ghz 2700k @5.1-5.4ghz no problem to run my @5.4ghz before a migrated to IB 3770K

Lol I accidently also wrote cache as "cash". Because I think cache is pronounced as "cash", or isn't it? :Big Grin:

I have to disagree here Hasse.

 

much stronger memcontroller? for all I know it's exactly the same IMC for both the 2500K, & 2700K. remember they're both SB, not IB

It doesn't clock 300mhz higher in average, maybe 100MHz

Also the extra 2MB of L3 cache is a non factor, even in most synthetic benchmarks

I have to disagree here Hasse.

 

Me to my friend i disagree to booth ^_^

It can be more difference inside the 2500k D1 D2 than 2500k D2 2700k D2.

D2 has a stronger memcontroller and clocks better with lower voltage.

 

The extra 2MB of L3 cache , Nick N think that but its like the BP=0 tweak he dont seems to like " rude to Word Not Allowed" i tested booth prefer Kostas tweaks on my system.

 

If we all have the same thoughts it would be boring, this is very close its our own reverence to what average is OK!! we put it to 200mhz Dazz is it Ok for you? ^_^

Do you have a link to back that up? Not challenging you or anything, just curious. Even if it was true, what are we talking about here? another 100-200MHz for the 2700K and a wopping 2% performance boost?

I wonder why Nick recommends IB over SB-E considering the extra L3 they come with. Personally I don't buy the L3 cache thing. It doesn't even make a difference in most benchmarks let alone FSX

Well, I'm basing it on this

Funny how 6 out of the top 7 are 2500K.

Some time ago Corey plotted that spreadsheet and the 2700K was 100MHz above the 2500K at the same volts, but the sample of 2700K was too small back then, anyone care to plot it again?
