2500k vs 6600k?

[Jumper118]

well z68 just had functionality to use the integrated graphics iirc

ok. i didn't know that. thinking about it i dont think i've ever used igpu on an intel cpu ever! i've always had the gt610

[LabRat]

In that review/test it seems the 6600K is at 4.5 while the rest are stock based on the wording.

 

5Ghz is easy on sandy

[iHardware Shelden]

Now that is a good looking motherboard, I think you will be happy with how it performs  

 

[Umeshwarnath]

I wouldnt be surprised if your 2500k hit 5ghz with little over stock voltage......show me one 6600k that can do that! its a great chip man! but as far as IPC goes the 6600k is much better.....shouldn't be a problem though...the 2500k is still great!

Looking to achieve around 4.2-4.5GHz and I'm happy

Yeah, just tested to see if it boots and everything is fine My brother found the motherboard on OC3D and the CPU around my area (how lucky) all for £80. BARGAIN! The owner didn't overclock the CPU at all as far as I know. No idea why he didn't tbh  :mellow:

 

2500k is still a beast. Upgrade your gpu and your system will be good for many years. As for your question 2500k vs 6600k? Depends on cost and what you can afford. Sounds like the 2500k was a gift? If so keep it and enjoy

GPU upgrade is out of the equation... for now at least. The GTX 670 is still amazing at 1080p and I'm not upgrading above 1080p anytime soon so I'm good Yeah, my brother gave it as an early christmas gift as we really needed a new computer as my current one is aging badly.

It actually is! Looks better in person! Was surprised at how big it is since I'm used to looking at a Micro-ATX board

 

 

 

Now time to go buy new RAM, case, cpu cooler and an SSD

nope. 4.6ghz minimum

[harrynowl]

nope. 4.6ghz minimum

ditto that

[SeanAngelo]

nope. 4.6ghz minimum

seriously?!

 

at what voltage?!

 

ditto that

[FireFox]

The Skylake i3 beats the 2500K according to Digital Foundry, but It's still a very decent chip.

 

Single threaded it will but I can't see it beating it in multi-threaded tests even though Mighty Sandy Bridge is getting old now.

[harrynowl]

seriously?!

 

at what voltage?!

32nm is fine with volts, it's just 22nm finfet that had issues.

 

1.4v isn't out of the ordinary.

[Jumper118]

seriously?!

 

at what voltage?!

i ran my 2550K@5ghz on 1.4v for ages. used to do 5ghz on 1.38v to start with. sandy ran so cool i was at 4.4ghz on 1.2v on the stock cooler

It is a shame the mighty architecture is getting old ehh

 

@OP - Gaming performance between the 2500K and 6600K is going to be barely noticeable, stick with Sandy Bridge mate and save your money.

[Dabombinable]

Sandy OCs like a beast - puts Maxwell and Vishera to shame

Pst, Netburst is the best overclocker if you have a decent cooler a cooler that would suit an FX 9590 running at 5.3GHz+.

[FellTheSky]

i would grab the 2500k over ANY other locked intel CPU, even i7's.....

[Keudn]

Stock its a bit slow since it is so old, but it overclocks like a champ and can still perform good then. I have mine at 4.9GHz with a 212 EVO

[Dabombinable]

But its a 6600K....and not the shitty APU made by AMD.

1.4v isn't out of the ordinary.

I'll try giving it 1.3v and see if it runs 4.6ghz maybe i'm underestimating the overclocking capability of this CPU too much  :lol:

That's my base then... 4.4ghz at 1.2v

Born in 2011, just going to 5 years old

 

Yeah, figured might aswell save money and buy a decent cooler for overclocking along with a new case, ram and ssd.

Seriously? I personally would get an i7 over the 2500k hahah  :lol:

What temps are you getting at load and idle?

[Keudn]

What temps are you getting at load and idle?

Mid 80s with Prime95, dont remember my idle its not above 40 though. I never see it above 80 though since you never really end up with the same load as Prime95, even while folding

Well I'd take a DC/SKL i7 over this but not Ivy or Haswell

 

Even sandy-E is boss

I'm guessing this is at 1.3v?

 

I'm getting a H100i GTX so the temps will be a bit better than yours I believe.

Uh don't remember, i think a bit above 1.3V

Other than the framerate difference, notice how frame times are much smoother and consistent with 6600K compared to all other CPUs tested.

[SteveGrabowski0]

Wow, that's a pretty sweet gift. The 2500k is a pretty good gaming CPU at stock, but it's also one of the greatest overclocking chips ever made. It certainly won't even come close to bottlenecking a GTX 670 and with even a mild overclock it should be awesome running games at ultra with any gpu you can find right now if you're targeting 60 fps.

 

Here's what Tom's Hardware has to say about the 2500k in its article about the most legendary overclocking chips ever made:

http://www.tomshardware.com/picturestory/636-15-best-overclocking-cpu.html

 

Intel Core i5-2500K

 

Intel introduced its Sandy Bridge-based chips in 2011, built on a 32 nm process. Compared to the top-end Core i7 CPUs, the Core i5s lacked 2 MB of shared L3 cache and Intel's Hyper-Threading feature. Neither of those nips made a huge performance difference, except in heavily-threaded workloads.

On the other hand, the Core i5-2500K included an unlocked ratio multiplier, making it possible to push the stock 3.3 GHz CPU up as high as 4.5 GHz using air cooling. We considered the $225 price tag reasonable, considering the chip's high potential performance. Even today, relatively meager gains from Ivy Bridge and Haswell make the -2500K a strong choice for mainstream enthusiasts.

[Cheddle]

So I just got surprised by a new cpu and motherboard, and it's the i5 2500k and Gigabyte Z68XP-UD3P.

 

Now I'm pleased about the surprise but is the 2500k bad compared to the current gen i5 6600k? Because that's what I was hoping to upgrade to but unfortunately not....

 

Are there any big differences?

 

My specs are in my profile, take the cpu, motherboard and ram away from that and replace it.

 

What is the performance increase from the ancient Intel Core 2 Quad Q8300 to the i5 2500k?

 

I was also surprised to see Z68 instead of Z77 because I though Sandy-Bridge is Z77? :huh: So, what is the difference between Z68 and Z77?

 

Thanks in advance,

Sean.

 

you will notice a difference going from a q8300 to an i5-2500k :-) after the i5-2500k the improvments on each CPU have been really quite small... some even preffer the 2500/2600k to the newer chips for their great overclocking

 

the gtx670 wont be held back by an i5-2500k.

 

While it is a little dated now the i5-2500k is certainly fine, and with a little overclocking it shouldn't impact your experience at all compared to a newer CPU even in new AAA titles. 

[Swndlr]

where the heck is he getting those numbers??

lol

its not as simple as "12% better"

every game and program will perform differently

just looks at game benchmarks and compare them

+1

And also, if I do remember correctly, upgrading from such an old chip to something new like a 6600K should increase frame times and consistency, making the game have less stuttering and frame dips. If I can find the video where someone tested it Ill bring it up, not sure if it was an LTT video or someone else like JayzTwoCents
