3570k vs 2500k

[BonzaiDuck]

If I really feel the need to have the latest and greatest, I can always wait for a revised IB stepping......or something.


To sum it up, just because it doesn't pertain to everyone doesn't make it an irrelevant consideration.

That's what I was thinking. ShintaiDK or somebody had posted an Intel chart per planned chipsets over the next few years -- the skt-2011 seems to be a dead-end. I was thinking that we could see newer IB's and steppings for skt-1155 soon.

There will most likely not be any new IB steppings. No need for it. And by most likely I mean 95%+. Unless a new IB stepping is already in progress you wont see any. Its simply too late. And not sure what you expect from a new stepping? There is nothing wrong with IB.

LGA1155 is deadend too. Haswell and Broadwell is LGA1150 (Due to ondie VRM.) with the 8 and 9 series chipsets. Last chipset on the mobile and desktop btw. Skylake will have the chipset integrated. Some Haswell and Broadwell mobile chips will have the chipset onpackage.

I'm afraid that integrating everything on the CPU like they plan will make them run 100c temps. Wait and see though.

Mostly speculating on the basis of past history -- without looking more carefully at the already-unfolding lifecycle for SB and IB. There were improved steppings for Wolfdale around '08, and we saw it earlier with a G0 release of the Kentsfield.

Stop saying "easier to cool." Ivy Bridge runs hotter than Sandy Bridge, and it is perfectly okay for it to run hotter! Just because your 2500K runs at 60C full load doesn't mean that a 3570K needs to do the same to run at a "safe" temperature.

I understand your point, but here is mine.

2500k @ 4.5 GHz will run almost equal to a 3570k @ 4.3 GHz, and temperatures will more than likely be easier to control with the 2500k, while being cheaper to purchase, and can run on the same Platform.

This point is valid unless you are spending more on cooling and upping that O/C on the 3570k which is even more of a cost. (H100 or so needed). I also state both are fine.

Why spend $50 + for IVB? Just so you can say I have the "newest tech?" I think this is a valid point for many users.

 

[Phynaz]

Get the 3570K, OC to 4GHz (default vcore) and you should be fine for every game. HD7850 will be the limiting factor most of the times.

This.

How to overclock a 3570K:
1. Enter bios.
2. Set Multiplier to 40
3. Profit

Temps are no more difficult to "control" with IB.

Around here IB costs $20 more than SB, and gets you the new Quicksync engine, PCI 3.0, higher memory speed support.

Yeah, cause Quicksync, PCI 3.0 and high memory speed is really changing the game.

I'm not arguing, I'm just stating the 2500k is a better value right now for majority of people out there. Nothing more!

 

[Phynaz]

Who said it's changing the game? I said those items, along with the higher IPC, are worth $20.

 

[cmdrdredd]

People talk about value but neither of these CPUs are exactly value parts at all.

 

[aayjaay]

People talk about value but neither of these CPUs are exactly value parts at all.

What do you mean? Value as in 'cheap' or value as in 'value for money'? I'm guessing the former.

Also, as for overclocking the 3570k, I've read that many people can get it to ~4.3, maybe more, with only a 212 CPU cooler, pretty good as it only costs ~£30. Don't know if all of those reports are true but it doesn't seem too challenging to get a 3570k to the mid 4ghz range. What would load temps be like for an overclocked 2500k vs 3570k by the way? I may have asked this before, I'm not sure. Oh yeah, I also wanted to ask, if there was an improved version of the IB coming out, what would it be and when would it come out? Would all the IB models be improved?

Ivy runs hot but improving your cooling does little for it. You're probably going to do as well with a cheap aftermarket cooler as with top-end water. Only sub-ambient cooling makes any difference.

 

[santilmo]

If you're running IGP (who does with a K CPU, lol), or running stock speeds (Again, WHY with a K series CPU!?!?), then the Ivy will be a little better. The IGP still sucks, but less so to some degree.

Well, I am one of them...

1.) I use IGP (for now) and always prefer to have an IGP just in case my discrete GPU gets fried or something I could still use my damn PC... 😉 Also, If ever I am in dire need of an emergency cash, I can sell my discrete GPU and still be able to use my PC.

2.) I bought "K" though I don't overclock (yet) because it has a better IGP and I would always prefer to have these options at my disposal anytime I would want to overclock so in that case, there's no reason for me to upgrade anymore... 😉

Bottomline, I prefer not to OC (for now) because of power consumption and heat issues... Besides, the stock power of 3570K is more than enough for me (again, for now)... ^_^

There is nothing to "control" why would you need to run IB at the same temp as SB? You don't. So they'll perform equally at the speeds you mentioned, IB may run warmer but you dont need to do any form of extra "control". But it will STILL produce less heat, consume less power, have a better IGP and PCI 3. At those speeds there is zero reason not to go IB.

depends on your mindset.
a 2500k a z68 board a hd6870 is 200 dollars maybe 250 less then a 3570k a z77 board and a hd7850 gpu and in a year or 16 months you could decide on has well cpu with a new mobo.

the op could get into the hobby at a better price point. while learning.

if you are not over clocking the op can find a good z68 board from 85 bucks . drops him down to 470

What do you mean exactly? If you're saying that I should wait around a year for prices to drop, there wouldn't be much point here in England. As of now, the 3570k is ~£10 more expensive, a Z77 like the Gigabyte DH3 (I've read you can overclock pretty well with it) is ~£5 more than a Z68 and yes, the 7850 is ~£60 more than the 6870, however isn't it a much better graphics card?

EDIT: Thanks for that thread by the way Yuriman, pretty useful. ~70 degrees (maybe a little higher with air as I'm guessing you're using liquid?) is pretty manageable for a 4.3ghz OC which I'd be pretty happy with.

 

[philipma1957]

if the price spreads are that close my idea does not work for you. at 470 vs 657 usd it makes sense.
you could use the 180 to get a nice ssd.



At 15 pounds difference not counting the gpu you should get the new gear.

I used the 6870 vs the 7850 because they are closer in performance then the price increase ratio.

see ratings below

http://www.anandtech.com/bench/Product/540?vs=549


the 7850 is 20 percent better and cost 35-50 percent more. All usa prices which don't mean much if they are far different in the UK!

A lot of times price vs performance can cloud the choice. If I built the two machines I could hunt for a week and the older gear I could find for under 400 the newer build would be 625 at best.

For most users at that price point the older build is better. As long as they are not tooo crazy about winning head to head gaming and try to beat personal best scores.



I sometime forget this site has many countries reading it and prices vary a lot from place to place. So value assessment can be difficult.

I'm talking about the processors. You can use the same board and mem with either one so no need to compare anything but CPU. You can also get a Z77-D3H for less than $120

 

[Hatisherrif]

If you were a maximum overclocker with appropriately powerful cooling I would strongly recommend SB. The maximum 2500k overclocks can overcome the IPC disadvantage if you're willing to push it. For mild 4.0-4.6 overclocks the 3570k is the better option. Or neither and wait for a revised IB stepping..

Wow, you really consider 4.6 to be a mild overclock? I can't hit more than 4.5 on my i5 2500K.

Is 1.315V the fully-loaded and drooped voltage (for whatever LLC you're using)?

I was able to get my 2600K to 4.7, but I run it at 4.6. I'm not sure -- in that range between 4.4 to 4.7 -- that it matters too much.

The IB sports PCI-E 3.0, and despite using the same memory controller as the Sandy, has an ability to use memory clocked higher than 2133 to advantage. Even there, the advantage is still a sliver of improvement. As for PCI-E 3.0 and the more powerful iGPU, it can't matter too much to me unless I were adding a twin GTX 570 for SLI. And -- correction -- that would make the Intel 4000 iGPU of little consequence.

If I were building a system this year, I'd get the Ivy Bridge. But I built it last year, and I'm still able to wring a few more performance improvements out of it to feel pretty good about a year-old SB system . . .

 

[buklau]

I would just get a 3570k as it has PCI-E 3.0 and higher memory (> 2133 for sandy).

The 3570 has a 200-300Mhz lead on the 2500k with it's IPC improvement and is not limited in OCing like people seem to think. You can hit 4.5 - 4.6 with a good air cooler and have reasonable temps. Using a good thermal compound like liquid metal pro will also help temps quite a bit. I popped the IHS off my Ivy Bridge CPU and re-applied good thermal paste instead of the cheap stuff it ships with and dropped my temps by 10c.

 

[BonzaiDuck]

Yup . . . Maybe the first thing in any forum-member's mind before the release of IB was the same thing we always hoped for -- higher achievable CPU speeds. No such luck, but now the RAM-overclocking possibiities are opened up a bit.

Just makes more sense to buy the Ivy now.

 

[felang]

Stop saying "easier to cool." Ivy Bridge runs hotter than Sandy Bridge, and it is perfectly okay for it to run hotter! Just because your 2500K runs at 60C full load doesn't mean that a 3570K needs to do the same to run at a "safe" temperature.

Also, even though IB runs hotter, it releases less heat overall and is more power efficient. Really no reason to go with 2500K IMO.

With those components I would go with 3570K and lower PS from 600w to around 500w.

 

[santilmo]

400W PSU will suffice for an IB system along with current generation GPUs (provided that you don't do multi-GPU)... At 500W, you already have a headroom.

My IB rig only consumes around 60watts for a typical usage scenario and around 130watts when loaded (no GPU yet as I am still using HD 4000). Say, let's add about 200watts for a discrete GPU and another 50watts for all other components...

By the way, that's just the CPU alone (no monitor)...
