Question On 2500k at 4.6ghz

[Mussels]

well an overclocked 2500K will trash anything AMD has, so it certainly 'beats modern chips' quite soundly - it's a tad silly to compare it to the best of the best

 

[trt740]

Here is a good comparison of a top end chip overclocked equally, and the 6700k is faster but the 2500k is very playable and still very fast considering it cost $70.00-100.00 currently on eBay. Per price point it is a beast to this day. If it were still being produced, I would bet it would still be selling like crazy.

Remember this is a top end i7 skylake against a Sandbridge i5 both at 4.5 GHz. I would have liked to see a 2600k but it did not happen

you could match a relative performance with your sandy, which is normal stuff, but the new processor incluides new instructions, higher memory badnwith and controller, performance does benefit with clock speeds and frequencies, but there are moar tasks involved to match or beat bro,

which new amd chips? people have been waiting for zen, other amd are still older chips on a dead socket...

Still, the real world performance increases are still not as great as you might think.

perhaps might be something to avoid due real world situation, im pretty sure that your i5 still pretty capable to reach 4.5GHZ or beyond which is also a great OC and could handle another couple of years of service

I picked up a i7 3770k just because I got a deal. It cost me about $140.00. So after I sell my 2500k, it will be a very cheap upgrade. I'm betting I see zero difference. It was most likely a waste, but it was cheap, and if newer games support hyperthreading , then it may be a boost. I most likely will drop $89.00 on some DDR3 2400, and I will be done for a year or two more. I looked at other upgrades but combined with the pain in the rear rebuild and cost this was a cheap and quick upgrade. Frankly, I really like my current set up. I might just skip the ram upgrade my current kit overclocks up to DDR3 2133, but if I sell my current kit that would end up being a $20.00 upgrade. Again, I'm convinced this was a waste but we will see. It will give me a few boosts since I have rev. 3 mother board in the graphic area and USB 3.0

try it out, will be boosted

I don't know... I guess I feel it isn't terribly fair to compare it against a highly overclocked CPU not allowing it to flex its own muscle. I happen to disagree that nobody would buy a new CPU if it didn't beat out the old. but, to get get into that (other features), distracts from the point of this thread, so I digress.

It was a waste... outside of the HT, agreed. You'd have been better off getting haswell. Rebuilding a pc is nothing when done right (both hardware and software wise).

From what I read there is zero performance increase from Ivybridge to Haswell at the same overclocked. I just read one where a i7 3770k beat a i7 4770k sometimes at the same overclock and equals it at other times. I'm trying to find it now.

Here are two I read . They are a bit old 2600k , 3770k and 4770k in the fist one. The second one is 3770k verses 4770k

Just read the anandtech skylake review. I think i linked it in one of your threads.

Edit: http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/9

This graph shows that:

Sandy Bridge to Ivy Bridge: Average ~5.8% Up
Ivy Bridge to Haswell: Average ~11.2% Up
Haswell to Broadwell: Average ~3.3% Up
Broadwell to Skylake (DDR3): Average ~2.4% Up
Broadwell to Skylake (DDR4): Average ~2.7% Up

I'm not seeing chips overclock and compared , and I'm most certainly not comparing Skylake to Ivybridge. Your killing me here. Im not interested in a $1000.00 upgrade. Of course Skylake is faster. I'm looking at a $60.00 cost out of pocket to go from i5 2500k with DDR3 1600 to a i7 3770k and DDR 3 2400. I'm not sure where that came from but I did not post that Anandtech review.

I do see a comparable Haswell here

[EarthDog]

I guess im confused...

You said there wasn't a performance gain between IB and Haswell. I posted a link to the anand skylake review which shows the IPC difference between IB and haswell at nearly 12%. I saod NOTHING of skylake in the post above. You made a move where, in general, IB doesn't clock as far as SB did so you gained nothing unless you IB can hit very similar clocks. But, you did gain some threads. So when used, that will be helpful.

So, I think I see it now.. you are looking at performance only through the (myopic) lens of gaming. Missed that!!

I think you are a bit confused but that's okay it happens.

Na im looking at not spending a large amount of money for a new systems that gains 12 percent by intel changing some very minor things on a chip and changing the multiplier (overclocking basically a Haswell) when I can overclock an Ivybridge and save money and get the exact same performance. At the same clock there is almost zero gain.

However, the review does say this. But newer chips are generally a bit faster.


"Having a closer look at test results conducted with high resolutions, shows the same surprise we already found with quad core parts without HT, which means that Ivy Bridge is a tiny little bit faster than Haswell. The only thing that actually went different than expected was the Core i7-2600K being slower than the other CPUs. In case of lower resolutions, or in other words open the VGA bottleneck, we measured three percent performance difference between the Core i7-2600K and the Core i7-3770K as well as another four percent between the Core i7-3770K and the Core i7-4770K."


And then there is this from the review you posted

" When you scale up to a 4.5 GHz Skylake against a 4.7 GHz Sandy Bridge, the 4% frequency difference is only a tiny portion of that. "


However, Skylake does add other things to its arsenal, but again I'm not up for that upgrade at this point.

I'm still not talking about skylake.. this is too difficult for me right now...lol.

Good luck to you.

as someone who owns both those chips: the RAM speed increase is the winner there. 2400MHz (or higher if you're adventurous) kicks up the performance a lot in certain uses (fallout 4, for example)

Hey thanks Mussels, I currently have a kit that hits 2133 and a 2400 kit on the way. I will sell the 2133 kit and see where we go. The 3770k I received is a total beast (runs hot as heck but they all do). I'm selling my I5 so the upgrade should cost about $40.00 . I'm sure glad I didn't not upgrade to Skylake or Haswell. I had an entire systems in my newegg basket and almost pulled the trigger. I saved about $850.00 and I will be good for a few more years. Do not get me wrong I like the new chips, but I like money as well.

i de-lidded my 3770k and put a liquid metal TIM under the IHS and between IHS and waterblock, took about 30C off my OC temps.

2400mhz 1.5v is totally stable for me, but i cant get 2600 to even POST, dunno if thats a CPU thing or my ram - but my oh my is it glorious to OC and outperform newer hardware

all ivy bridge i7's tend to be quite hot, since they replaced sandies, which were the last soldered IHS to Die processors, so ivy's have started the process with thermal paste, i have delidded my processor and at least 5 ivy's more, mostly i7's locked and unlocked, its a quite great alternative to reduce temps! beware that its a ultra risky method, without a delid tool,

My 2400 runs fast. I Have not tired to overclock it yet but it is supposed to do DDR 3 3000+. Im going to plat with a bit and tighten it up.

Congrats on the purchase mate, I think you've done very well if it will roughly cost you $40 for the 3770K.

Ivy's are nice CPU's, you just need to cool them...

Have fun

 

[trt740]

I am geting the exact same results. My ram will boot at 2400 1.5v (down from 1.65v) but will not go one ounce higher. Not that it needs too. FYI ram was $90.00 not sure what you payed. Selling my DDr3 1600 that does 2133. Good stuff but not as fast, but it was $20.00 cheaper. Also, I put some better thermal paste on my cpu, remounted my heatsink, added higher CF fans to my heatsink, and my temps dropped about 5c underload. I still cannot get truely stable at 4.5ghz without 1.3v and the temps just go crazy. It seems at 4.2 to 4.4 ghz this chip is fast enough anyways. It benches on par with the newer chips. I have noticed at DDR3 2400 it takes more voltage to overclock my cpu. Not a giant amount but that is to be expected since this board orginally only supported DDR3 1866.

I bought a SSD and some quicker ram as well so now my system is completely upgraded for about $500.00 less than a complete rebuild after I sold my old stuff. However, if prices drop this week, I'm not above a sell off and a completing a rebuild. If I did, it would just be because my motherboard, as great as it is, is getting a bit long in the tooth. However, that secnario is very unlikely. My systems is hammering and is performing nearly as fast as anything out there.

 

[Kursah]

All that talk about OC-ing DDR3, and I've decided to push the Crucial DDR3 1866 4x4GB kit I have in my main rig. As-much-as I'd like to buy 16GB of 2400, I just can't at the moment.

But, I had been stable at 2133 for some-time, pushed and got 2200 without too much more work. Right now I'm pushing 1.65v and 11-13-13-31 timings...not stable at 2400...well bench stable. Boots to Windows fine-ish.

I figure 2400 might be asking too much out of these sticks...but 2133 was pretty damn easy to achieve...mostly just relax timings a little bit, and a small voltage bump to 1.55v.

And before I finished this post, I talked myself into grabbing those Corsair Dominator Pro's from Newegg for $96 shipped for 16GB (2x8) 2400 CL11....until they arrive, challenge accepted on my current RAM without smoking em...as I may sell them to recoup some losses or better yet...cover it up before the wife notices!

Also, after reading you were able to achieve 2400 @ 1.5v, that has my interest as I love to run undervolted at high speeds with stability...you know air cooling and all, it helps plus it adds a good challenge. My CPU voltage tuning took forever...I first undervolted at stock (4.0, and 4.4 turbo)...then once I found that stable...started OC-ing. The Z87 board I use has an adaptive feature which will only add voltage on the turbo clock voltage. In short I add an extra offset to compensate for the undervoltage using the adaptive so I have the voltage I need for being in the turbo clock range...yet can idle nice and low. I also noticed that setting the ring/bus min. multi to 8X from 40X (default 40 min/max), drops idle power consumption...I was able to notice this from my UPS even. Not that any of this helps you or this topic...more-so you inspired me to tune further even though I was content! That's what TPU is about!

Glad you're happy with your upgrade path @trt740 , the one issue I have with these budget SB and IB builds is the mainboards. Getting more expensive to find the good ones...but when you already have a good board, why not? I still think you should delid your 3770K. I want to delid my 4790, see if I can get 5GHz on air... but I'm gonna wait until the warranty expires.

Regardless, looking at the 7700K reviews, I don't think we're missing much if we're not taking advantage of the newer features that Z1xx and Z2xx boards bring to the table or are worried about decoding 4K videos.
