Reviews - Intel Core i5-3570K (22nm Ivy Bridge)

[Phage]

Let me know when you sell the 2600k.

Interesting could mean a lot of people stick with their current desktop until a suitably powered tablet comes out or a reasonably priced ultrabook or something like that.

At least that's how I look at it.

Potentially but it's worth noting that Haswell is going back up to 95w parts, where I expect there will be a shift back to performance enhancements. This was just a die shrink mostly and a particularly unique one at that which follows rather different rules. Usually at a die shrink they would bump up the performance more but the nature of ivy bridge's 22nm process seems to lend itself to simply reducing consumption

Haswell is more about improving GPU performance,and I expect more effiency improvements to the CPU so that more of the TDP can be spent for the GPU.

Anybody know what the deal is with Speedstep? What I mean is what frequency will the chip idle at with SpeedStep enabled.
If say it is overclocked at 4.5Ghz (45*100) with about 1.1v. Can SpeedStep still be enabled, and will the low clocked frequency still be the same?

My current Q6600 offers a low state of 2.4Ghz (6*400), would just like to know how the i5's (2500k or 3570k) work.

I'm not sure about the idle frequency, but yeah it should still be the same as stock and work fine when overclocked. There's more to power saving features than dropping the clock though, voltage will be reduced and now power gating plays a large part by disabling idle parts of the chip to get idle power consumption of the CPU to just a few watts.

I can't remember off hand but my 2500k is at 4.6GHz using the auto oc features in the bios and as such it still idles down to about 1.1GHz I think. Vcore varies from 1-1.35 ish.

[Scainer]

I just read that the 2500K is 16 - 33 meaning 1.6GHz, so now i'm off to find any info on the 3570k
I'm interested because I am thinking about the heat issues and seeing that efficiency is word for IB its strange nowhere mentions it.


I'm going to assume its 16 - 34. If retail reviews show 4.5Ghz is safe and stable I think it will convince me to visit the bank.
Also waiting on the reviews of the Dark Rock 2 / Pro 2 (nudge nudge, wink wink)

Just fired up cpuz and ibt and it's running at 1149 MHz idle at ~ 1v and ramps up to 3.3GHz at 1.34v when not ocing. Thats everything on auto.

Edit: Scratch that just put her back up to 4.6 GHz and took cpuz from 1.6 to 1.61 as it was misreporting stuff. 1602MHz 16 x100 @ ~ 1.04v and then 4.6GHz @ ~ 1.4v, 35 - 77c (ibt makes it hotter than most situations). That's running an H60 cooler. These newer processors have a lot of good power saving features in and temperature is a big deal to me as well.

[watercooled]

I wouldn't let it bother you, it's not mentioned a lot because it's largely irrelevant; idle clock speed tells you nothing about power consumption. In fact, clock speed itself doesn't have much of an impact on power draw, the reason it's reduced is mostly because the transistors can't switch as quickly when operated at a lower voltage; when the voltage supply to the CPU is dropped, it would become very unstable if the clock wasn't also dropped - like how you can't OC a CPU to 5GHz at stock voltage.

well im getting this cpu when they are release it for sell ive been waiting for sometime now for the i5 2570k

[watercooled]

What are you upgrading from? If it's just a CPU upgrade from SNB I'd save the money for at least the next gen or to upgrade a different area. Not having a pop at IVB, just jumping a single gen usually won't give you a noticeable increase in performance.

[steve210]

well im building my first computer so im going to have this in it
CPU: Intel i5 3570k 3.4 turbo boost 3.8 GHZ GPU: nvidia gtx 670ti: MEMORY 8GB G.Skill ripjaws 2133 ghz MOTHERBOARD: gigabyte z77x-ud3h HDD: western digital re4 500g SSD: Mushkin Enhanced Chronos 120g COOLING: CM Hyper evo 212 PSU: cosair hx750w MONITOR: asus 22in. 1080p LED CASE: COOLER MASTER RC-692-KKN2 CM690 II KEYBOARD: logitech k360 MOUSE: Microsoft Wireless Mouse 3500 OS: Windows 7 64bit

[watercooled]

Good choice of components. But if you're after advice, I'd replace the WD re4 (an enterprise drive) with a 7200 desktop drive and save a bit of money in the process. I'd also consider a lower wattage power supply, unless you're planning on overclocking, even a quality 450w would be fine for that build, or to be safe and allow for upgrades, I'd go for ~550w - of course I don't know what power consumption is for the 670 but it's pretty safe to assume it will be lower than the 680, and a 680 and SNB-E CPU doesn't break 400w when gaming.

[Methanoid]

What a pity the reviewer didnt think to overclock the IGP... the one thing I have yet to see from any Ivy review. Missed a trick there Hexus :-(

[bigdaz84]

I hope that the almost endless amount of people suggesting that others waited for ivy bridge for their new builds now shut up. I doubt it though.

[Wolfsbane2k]

Well that's a shame. Finally have the money for a new computer as an upgrade from my aging Phenom X3 720 (at 940 speeds and core unlocked) and i think i'm going to back a year in terms of tech, hoping that the 2500k's reduce in price on the second hand market as people swap to the 3* series....
