Intel Broadwell Thread

[DrMrLordX]

Was it an ES or retail chip?

If you are referring to Fugger's chip, I think it was retail.

so can you overclock the IGP or not? all results I see on hwbot are with the stock IGP

Fugger couldn't get it running faster than 1300 mhz.

 

[crashtech]

I'm somewhat disillusioned at this point. I see some prebuilt systems with these DT chips, but enthusiasts have clearly been left out in the cold. Need to find a new hobby.

If Intel comes with their own version of HBM... no one would need nVIDIA anymore too 😀

Well NVidia doesn't have a HBM card out....only AMD does. It performs about equivalent to a GTX 980 but slightly less than a GTX 980 Ti.

The CrystalWell embedded DRAM (128 MB) also doubles as an L4 Cache for the CPU.

I'm really convinced with this type of performance we might see a console from Intel for the 9th generation - and it could potentially be backwards compatible with PS4 / XBOX One.

Better performance and efficiency, plus if I'm building HTPC, I want small & no discreet card..

Yes, if you have an absolute criteria that there should be no discrete graphics card and you still want decent GPU performance and don't care about price, then I can see the Broadwell 5675C being a good option. Maybe the 65 W TDP is a bit high though, I myself would preferred 35 W or less if to be used for HTPC. Anyway, I think that's one of the few cases this CPU makes sense.

Otherwise e.g. a combo like frozentundra123456 mentioned here would be a better option, i.e. a i7-860k + 260x combo for around $175. But that's just one example, there are lots of other options that are better than the 5675C.

He was refering to AMD 860K :biggrin:

Core i5 6600K will not have an easy time beating Core i5 5675C in CPU limited games that benefit from eDRAM:

Overall

www.hardware.fr/focus/112/core-i5-5675c-broadwell-cote-cpu-test.html

Definitely a viable upgrade path for LGA1150 users, I just hope availability (and retail prices) improve. Too bad Broadwell-K's launch was so close to Skylake-S, I feel like this chip is underrated. The CPU performance it provides for dGPU gaming alone justifies the MSRP (Intel ARK) price, then there's the best in class Iris Pro iGPU and much better efficiency than Haswell (something many reviewers could testify).

If Intel keeps 65W Skylake 4C+GT4e (64MB eDRAM) clocks high enough next year then this might be a better gaming chip than 91W 4C Kabylake-K (assuming Kabylake packs higher-clocked Skylake cores, not a 14nm version of Cannonlake cores).

Ahhh, of course! It wasn't clear from his post. How confusing for Intel and AMD to have the same model number like that. But I was too quick to jump the gun, and Intel's 860 is in fact really old (from 2009). 😳 Anyway, with the AMD 860K the point is still valid though.

Good eye, I missed that.

R390X performs about the same as GTX980, Fury and especially Fury X are way above that performance level.

some PCLab.pl tests

power efficiency and performance is really weak compared to the 750 on Witcher 3
http://pclab.pl/art64766-3.html


in some other games, it looks better, but Witcher 3 is playable with a $100 card and not playable with Iris pro 6200; something to consider.

 

[dark zero]

Lol! And even Godavari manages to beat Broadwell (with low margin).... with a process 3 generations behind!

If AMD could move Bristol Ridge on 22 nm SOI.... only to make time to squash Intel with their HBM Zen APU on GPU (remember that the GPU is really strong... they need dedicated RAM... I am wondering what happens if that GPU has 128 Mb eDRAM)

You might want to check the other tests, Broadwell-K beat Kaveri in all of them. 🙂
They probably need some drivers work in The Witcher 3 and some other titles.
Also better get used to Intel's lead cause all AMD has planned for next year in terms of APUs is another 28nm rehash.

Two new reviews guys, Techspot and Guru3D

Techspot's Core i7 5775C Review

- iGPU Gaming

Much better performance in Crysis 3 and Tomb Raider, interesting.

- Clock per Clock Comparison

- Power Consumption

- OC Performance

Where the 5775C shines is in its 3D performance, and we hope AMD has been taking note. The Iris Pro 6200 makes the 5775C the fastest socketed processor available when it comes to 3D rendering. AMD’s A10-7870K was simply no match for the i7-5775C in any of the games we tested.

The 128MB of eDRAM which acts a bit like a L4 cache was the key to the 5775C’s amazing 3D performance. That said, we suspect it came in handy on the CPU side of things when running a few of our application tests, where the 5775C was surprisingly fast.

Guru3D's Intel Core i7 5775C Broadwell-H Review

The GT3e GPU that is embedded alongside the L4 cache chip is powerful opposed to what Intel has been releasing for years now. I mean to date there hasn't been a desktop processor from Intel that was capable beating AMD APUs. Broadwell-H Desktop processors come with a very feisty solution, and if you stick to mid-range quality settings, you can actually play games at 1080 reasonably well. Truth of course remains, everybody that purchases a flag-ship quad-core processor, will likely already have a dedicated graphics card. But yeah the GT3e IGP is good, really good. We also need to separate gaming from the graphics core, realize that it is a multipurpose graphics processor. You'll have no issues with Blu-ray playback, heck it can even deal with 3D TV, post-process your media files and help out with video en/trans and decoding. The GPU is compatible with HDMI 1.4 and Display Port 1.2 next to the regular DSUB and DVI connectors of course. Unfortunately HDMI 2.0 is not supported meaning 60Hz on an Ultra HDTV will max out at 30Hz.

The biggest benefits for Broadwell-H are twofold: impressive integrated graphics performance and a notch gained in power efficiency. Somehow I have the feeling that Broadwell-H for desktop is sort of a initial tryout to see how 14nm is behaving. As a result the performance is good, but relatively clocked low. And then overclocking results are a bit dull. The performance increment overall is close to NIL. So with that said, if you already are on Sandy-Bridge, Ivy-Bridge or Haswell, we would not recommend you to upgrade. See, what you want to wait for is Skylake, which is launching very soon already. That desktop processor series promises new motherboards platforms with new features and a processor that will get you a fair bit more in performance and tweakability as well. In retrospect I do have to mention that the maximum turbo allowance for the 5775C is 3.7 GHz, and it can keep up with say a 4790 really well. So in that respect the per core performance has increased a bit.

Hardware.fr Core i5 5675C Review


Their efficiency test also puts Broadwell-K largely ahead of any previous chip.

www.hardware.fr/focus/112/core-i5-5675c-broadwell-cote-cpu-test.html

13.5% better efficency on average than Haswell at iso conditions, totaly in line with my 10-15% estimation for the mobile parts...

Certainly more (than said 13.5%) in the two archivers tests but less in FP and in other integer apps..

Holy crap that thing just crushes any CPU from AMD.

For the price, it dang well better.

 

[Phynaz]

Eh, it's the fastest mainstream CPU ever produced. It's going to be relatively expensive for a while.

For now, but Broadwell-K and the new line of Iris Pro desktop chips is here to stay.
If this week's leaked roadmap is correct higher clocked Broadwell-K arrives in Q3. Skylake GT4e should follow next year.

It is available in Germany.

Looks like you don't understand Intels Roadmap. Intel might look into a higher clocking variant option but there is no definite hint from the >= sign that it comes. In the past we didn't see higher clocking variants even with this sign in a Roadmap.

Since Skylake GT4 is H2/2016 they most likely will release higher clocked variants, doesn't matter if it's Q3 or later. I still stand by what I said, availability should improve in the coming months and desktop Iris Pro is here to stay.

What you are saying implies that there's not much of a performance gap between a 980 and a 980Ti but there is. 980Ti at stock is faster than 980 at stock by about 30%. 390X performs about on par with 980. Fury/FuryX are at a (heavily) overclocked 980 level. OCed 980Ti is in a league of its own. Overclocking 980Ti gives more of a performance jump then the one you get from stepping up to 980ti from 980.

http://www.3dmark.com/fs/5396318

my results practically matches that of my ex SLI Titans and that is without node-shrink, back in the days such improvements were only possible with both new architecture and die shrink, this time sacrificing DP64 performance and optimization of the architecture sufficed to provide nearly the same jump.

I can buy you the first 100 if you like. Just because its not on Newegg doesnt mean its not there.
