Today's equivalent of I5 3570

[s-h-a-w-n]

Hi, I'm looking todays equivalent of last year's I5 3570 in Haswell (or better).

Thats just a starting point, but it can be better. I would like to know the most popular performance-price Intel processor.

Additionnal infos:

Budget: Lower then 300$, good deals are appreciated.
Compagny: Intel, money is not the issue, efficiency is.
It could be an I7, but tell me what would be the performance gain.
No overclocking needed.

Thank you for your help, I trust your expert oppinion.

I5 4670K!

The i5-4670 is the "Haswell equivalent" to the i5-3570. Both are clocked at 3.4GHz and both have Turbo Boost speeds of 3.8GHz.

However, benchmarks have shown that the average overall performance increase from Ivy Bridge to Haswell is from 6% - 9% depending on which review site benchmarks you are looking at.

If you feel that 6% - 9% average boost in performance is worth buying a new CPU and motherboard, then go right ahead.

I5 4670K!

Thanks for the quick response.

So, considering I do not plan to overclock it, what would be the reasons to buy a 4670K instead of a 4670 (it's 20$ more)?
Call me silly, but I am also considering the i5-4670S (since the turbo frequency is also 3.8GHz), I like power efficiency...

I would prefer a Haswell or Ivy Bridge Xeon E3. They carry i7 features ( like HT ) at i5 prices. If OC isn't needed , get a Xeon E3-1230V2/V3 along with a Z77/Z87 mobo.

None.

On newegg 3570 and 4670 have 10$ difference, so I will take the newest. I will be upgrading from a Core 2 duo T9400... It is time for a major upgrade.

And about the Intel Xeon E3-1230V3, I don't know anything about server processors. I am open to learn more.

The Xeon is like the i5-3570 with hyperthreading capability of an i7. It also has no integrated graphics chip so it uses less power and runs cooler.

If you got the money might as well get the newer i5-4670 (non k since you don't overclock)
Newer processor and board will cost more but ultimately you still save when you upgrade just the CPU in the future. (More lga 1150 chips will be made, not so for lga 1155)

Ok I see, interesting.

I was tinking of using the integrating GPU for browsing, I think now we can switch between a card and integreted GPU when you dont need much power.
So what do you think of the I7-4770, is it worth the 90$ more then the I5-4670, what kind of applications would benefit fron hyperthreading?

 

[Lessthannil]

Discrete GPUs use around 15w on idle load.

 

[huilun02]

You'll benefit from hyperthreading when extreme multitasking, video editing and encoding, 3d rendering, all those productivity software.

If you just want to game and don't do all that stuff much then you don't need hyperthreading.

Shawn, for non-K chips Ivy Bridge's are still great overall, as Intel removed the +400Mhz bins limited OC from Haswell non-K's, so Haswell's maximum Turbo Boost is around 400Mhz slower than their equivalent Ivy bridge's.

I know you said "no OC", but if energy efficiency is priority, there's usually enough "headroom" on a 3570 chip to achieve both a simultaneous 4GHz mild OC (+17% performance boost) with a mild -0.05v undervolt. (At stock you can also often undervolt it by -0.1v).

Eg, I have an i5-3570 (non K) and I can do 4Ghz on just 0.968v load (and idles at just 0.668v - a crazy low voltage & power figures). At 4.2GHz (max possible speed for non-K), voltage is still only 1.064v load. At those voltages & speed, it maxes out at around 49-53w 4T Prime and often just 35-47w quad-core gaming / video encoding. At stock 3.4GHz speeds, it's virtually a 32-40w CPU in reality on 0.9v with 4 cores loaded. That's even more power efficient as some previous gen stock i3's. Of course, YMMV depending on chip binning.

It's also possible to mimic an "S" chip by tweaking the Power Control (Speedstep) options in Windows to 90% max load, which uses the second highest SpeedStep which on mine would "fix" the load at 3.0GHz @ 0.832v (roughly what a 4T loaded 3570S chip would get stock without Turbo Boost).

Just some food for thought, as you don't actually need to buy an S chip for low power consumption, whilst non-S (regular) chips still give you the option of overclocking to extend its lifespan in future. To "Overclock" often gives people the impression of searingly hot 5GHz chips & noisy fans, but with a mild OC to around 4.0Ghz + mild undervolt, that doesn't have to be the case at all.

 

[s-h-a-w-n]

Interesting, but are you suggesting a 3570 over a 4670? If its for the price difference, it was only 10$ on newegg and I need to buy a motherboard anyway.

Do you think it is better to mimic a S version with a K? Why would it be better since S is cheaper then K?

I am interested by your method, but I don't think I want do to much trial and error.

 

[CommentariesAnd More]

IMHO the i5-3350P or i5-3330 if you want iGPU. These CPUs perform as good as the i5-3570K.

There's simply no point getting a K if you're not going to OC it, as that's the whole point of the K chips - to achieve +4.2GHz speeds. With Haswell 4670 (non-K) you're limited to 3.8Ghz max Turbo Boost. With Ivy Bridge 3570 (non-K), you can go up to 4.2GHz (3.8GHz Turbo Boost +400MHz extra with a Z77 board). If you're not bothered about +3.8GHz speeds, then get the Haswell 4670, though you could go for a cheaper i5-3470 and simply upp the multiplier by 2 notches which would be cheaper still.

It's still worth getting a "Z" motherboard anyway even if you aren't overclocking (Z77 for IB, Z87 for Haswell), since that gives you the ability to undervolt which can easily knock off 10-15w TDP at the same clock speeds and makes much more of a difference than clock speeds alone. You might even be able to undervolt an S chip for extremely low TDP's.

If the price premium on S chips isn't too bad (over regular non-K chips) then go for that, but if they're much more than regular chips, you can achieve low TDP's with the SpeedStep tweak. I suggested this mainly in case the markup on S chips was high (they were at one point in the past and I honestly haven't looked at them since).

 

[s-h-a-w-n]

Ok, good, the S version is actually the same price as the ordinary, I just want it to work as intended without too much tweaking, some is good, but I may not want to do trial and error.

Thank you everyone, especially "BSim500" for your answers.

Thank you you to all your suggestions!
I got the 4670, I like it, and QuickSync H264 encoder is so fast!
