Broadwell vs Skylake: moving from Lynnfield I5-760

[stateofmind]

Hi all

1. My PC still works well, so no hurry
2. Uses are mainly crap like facebook, but also considerably amount of photo editing and sometimes video editing (mainly photoshop + premiere)

So, is there a good reason to pick Skylake over Broadwell? And, is there a sense in upgrading at all?

It would be nice to cut filter processing times in photoshop, but it's not something I want to pour money on.

Thanks all

Well, if you live in the USA, then you pretty much don't have a choice. I believe that skylake will be able to be purchased in another week or so after IDF. Broadwell doesn't look like it will be offered in the USA outside of a few pre-built systems. I preferred broadwell because I have a SFF system and wanted a 65watt max CPU. Guess I will be waiting until this winter when the 65watt Skylake CPUs are available.

If time isnt a concern then no.

But else it would be huge improvements to the 2, specially for the i7 version (Skylake).

going by memory...

1) facebook - no, even a phone can run that well enough so any 1Ghz + cpu is over kill
2) photo editing, unless doing batches, I think that is generally effected by the amount of RAM you have / the effects you are looking to implement.
3) what effects do you do with the video? if very basic ones, then the drive speeds matter more, so getting some ssd's or newer spining drives would be a good spend of money. If using a lot of effects, then a faster CPU might help out, but without knowing a lot more details, I do not think you will see anything like a halving of processing time.

Might be easier to just buy an i7 for your existing motherboard. An i7-870 or 880 has slightly higher clockspeeds, but the big improvement is Hyperthreading- the extra threads will help for video editing.

The benchs don't show huge improvement for the same class (I5/I7). Also, some Broadwell CPU come with much more powerful GPU

Mainly photoshop - motion blur and stuff like that takes a lot of time in my current system

but a lot more heat and power


I think that I'll wait to see what Zen has to offer

Frankly, there's no reason to upgrade from Lynnfield.

It's really hard to justify it indeed. I'm using an external GPU anyway, for Premiere and Photoshop (GTX 750 2GB used for $70) and besides saving 20-30W/h which are not that significant

Why didn't you include a comparison to Skylake?

Yes there is a sense on upgrading if you want better performance on photo editing and video editing.

Also skylake its faster then broadwell, overclocks better, costs less so it doesnt make sense buying a broadwell cpu unless you want a strong igpu

Broadwell has a big fat L4 cache, which could help in certain memory intensive workloads.

Going with the uses you mentioned where you can use more processing power is in hot and video editing, but you said that you don't want to throw money in that, so if you don't do it for a living don't waste the money.

It entirely depends upon what your time is worth. How many minutes / hours per week do you spend waiting on your computer? Is it worth $400 - $500 to cut that number in about half?

It was not necessary to make my point that Lynnfield is well and truly outclassed now.

I wasn't even going to include Broadwell...I dithered and then added it at the last moment, but it also was not necessary.

Broadwell is likely a no go due to lack of availability.

The new builds will be Skylake as far as I can see.

Well, first of all, yes, they are faster, but remember that it comes a lot from the much higher clocks (which is legitimate) and the other stuff from the faster iGPU (no iGPU for I5-760) and specific functionality added to those CPU. But still, they are probably much faster
I guess it could save some time when doing effects, but I still going to wait for ZEN and also, see what's going around with Windows 10, Skylake pricing, ZEN, HSA efficiency and all that

EDIT: forgot to say thanks!!

Can, but it costs money. I'm trying to wrap my head around the cost efficiency. I tend to buy a 2 generations old CPU usually.
I guess that anyway waiting for AMD ZEN might prove worthy

 

[Phynaz]

If you want to wait that's good, but don't get your hopes up for Zen. AMD's history of execution problems doesn't bode well.

I currently have an i5-760 as well and I am itching to upgrade.
Sadly Skylake doesn't seem to be the awesome upgrade I was hoping it would be, considering I plan on keeping this chip for another 5 years.

How do you think a new Skylake i5 or i7 would compare to an i5-760 running at 4.2 GHz?

I'd say a 6700K would be a big upgrade. You get hyperthreading, which boosts MT performance. Additionally, the IPC increase from Nehalem to Skylake in aggregate should be quite nice.

You also get PCIe 3.0, a much better platform, etc.

Skylake is a solid upgrade from Lynnfield, but you should only upgrade if you need to and/or want to.

Really depends on the use. For gaming, you'd be probably limited by the GPU, if your system is balanced (sounds strange, but still)

I think it would be better to wait another round for gamers

I'm not too sure if it's balanced.
I have a 290x right now.

Guess I'll just wait and see until Skylake is actually available here.

i5 version was in stock at Newegg not long ago.

That's pre-order. The release date is 08-14-2015. BTW, does anyone have any idea why the 6700k is absent, even for pre-orders?
