So is the eDRAM used for CPU as well or only gaming IGPU?

Used to speed up CPU calculations, if you're using a dedicated GPU. Anandtech previously tested this on a Haswell version with Iris Pro, it provided roughly 10% more performance compared to without it.

Even more pleased grabbed my 4970K for 170 from MM

I don't see any issue or point to bother to upgrade it its silly fast even at defaults 4ghz.

My next upgrades will be a decent 1440p IPS 120/140hertz panel or 4K, and Nvidias or ATIs proper next gen GPU with proper 4K support ability and support over the next year or 2 no doubt!

£170 wish I could get one at that price would forget about broadwell which seems not to be worth waiting for.

Seems that getting a 4790k back in September was a good move, should still last me a fair bit considering the glacial development of mainstream desktop CPUs;p

setter · 27 Mar 2015 at 19:29

Ill likely just hold on to my 4790k too, been through far too many cpu's lately. Setup in sig should tide me over till skylake providing nothing breaks.

altrewin · 27 Mar 2015 at 20:16

I think I'll be sticking with my 4790K as well, at least until Sky/Cannonlake or their X-series equivalents. May add another 8GB of RAM down the line, and if the CPU starts to become a bottleneck I can always overclock it a bit.

Supernova · 28 Mar 2015 at 09:15

I currently have an i7 860 (so just over 5 years old) and I was waiting for Skylake before upgrading. Should I continue to wait given these Broadwell specs, and Skylake supposedly not far away?

I think the i7 860 will just about hang on for playing Project Cars with. Watch Dogs and Project Cars both require an i7 3770 according to the developer, and Watch Dogs runs well with high/ultra settings on my PC.

I think that it will run better with a Broadwell CPU, but I am urged to wait for Skylake to appear.

Edit: I don't want to overclock or anything. I just want to put the new motherboard/cpu/RAM in and go

R3X · 28 Mar 2015 at 14:00

There are many guys out there with X58 and 920s overclocked to 4ghz and all is running smooth and fast, even in gaming.

Really don't see much point in upgrading, maybe when they get to 5ghz stock speeds in a few years time lol

Till then next gen gpus and 1440p or 4K panels seems to be the way forward I think!

Looks very disappointing for anyone who was waiting for these

Was there anyone waiting for these though? I think the vast majority of us had come to the consensus that it would be wise to skip Broadwell and hope that Skylake has more to offer.

All the more reason to stay on sandybridge for another year

Agreed, at this rate my 2500 K will outlast my Q6600!

opethdisciple · 29 Mar 2015 at 23:48

I *might* upgrade my mobo and cpu this year.

I’m rocking a 3570k @ 4.5Ghz, which I’m sure will be fast enough to get decent performance out of my 970 at 1200p when DX12 launches. But I might change my mind if DX12 scales well accross multiple cores.

I am tempted by a 5820k build. But think I should wait and see what Intel do this year.

Can some one enlighten me as to when the 5770k is rumoured to launch? What about AMD this year?

I think I will wait untill after Win 10 and DX12 launches to see what is needed to get the most out of it at an affordable price.

rare · 30 Mar 2015 at 00:00

I really think my 4790k will still be relivent in 3-5 years at this rate. Happy days.

Dave2150 · 5 Apr 2015 at 16:35

We should be engineering samples of these soon, if they release date is correct.

Hopefully there will be benchmarks to look at, so we can see how much of a difference the 128MB L4 cache (Iris pro) makes.

Mal X · 5 Apr 2015 at 17:43

i'l stick with what i have, i'll just get more RAM for next week

smilertoo · 5 Apr 2015 at 18:16

It's almost as if Intel have given up on faster cpus since there's no real competition from AMD.

MrAnthony · 5 Apr 2015 at 18:25

I'm really interested to see how these new processors perform. I've been forced into an upgrade up to Z97 after my Z77 board failed and I definitely want to jump up to an i7. Will be interesting to see if there are any significant performance gains firstly over my i5 3570k, and then obviously over the i7 4790k. If not, then I know what I'll be buying.

Any chances Broadwell will be any cheaper than Haswell? Especially since it's looking to offer less performance.

Yeh, I'm also very curious to see the performance data.

I guess the main issue is how well these new CPU's will overclock. This will be our first socketed 14nm CPU to overclock, so we're treading new water here.

It may very well be that the 14nm process is a better overclocker than the 22nm haswell process - as these new CPU's may have been simply limited to these clocks due to them being aimed at small factor/mini PC's, so the 65W may have been the maximum TDP they wanted to release.

Or it may be a terrible overclocker, we'll have to wait and see.

Loosing 2MB L3 cache over the 4790k should affect some apps/games quite a bit, though the performance implications of the 128MB l4 cache remains to be seen - Anandtech claimed roughly 10% performance improvement from the Haswell CPU's that had this 128MB cache.

WTB some engineering sample leaks!

eddiew · 9 Apr 2015 at 10:29

I like the TDP figures... but will it offer enough performance to prise my ageing 2500k out of my clammy little hands?

(I hope so, it's getting silly with how long I've had the core of this rig now!)

Bluntwrapped · 10 Apr 2015 at 13:12

Was tempted to pick one of these up on release and have a wee play with a cheap Z97 mobo but then thinking about it now I don't think I'll bother lol.

mikeo · 10 Apr 2015 at 18:42

I'm just going to wait and see what the reviews say when they finally arrive. Only then will we truly know how they perform both at stock and OC'd. Everything else is really just speculation at the moment.

C64 · 11 Apr 2015 at 01:48

gutted not to see a budget ish 8 threaded or 6 threaded cpu looks like even second hand they going to remain £200 + better off selling up z97 and haswell and going 2700k.
