It's not impressive at all to be honest. Airmont cores are half as good as a haswell i3 cores. So 72 Airmont cores translates to the raw power of 36 i3 cores clocked at 1GHz.
An i7-4960X is only $1,000 and probably outperforms this piece of shit.
Intel disappointing everyone, again.
>>51922215
Is intel just trolling us at this point?
>>51922687
Yeah it's pretty ironical, you'd think a GPU would be good at that stuff because of the ridiculous number of cores but a CPU still rekts it because of stronger less cores.
But this should be the middle sweet spot of multicore computing, this thing has a large number (72) of strong enough cores, so it should perform very well
>>51922731
Those are real physical cores you faggot, that thing probably eats your i5 for breakfast while fucking an i7 in the ass while whipping an i3 with a whip all at the same time because 72 cores
Sell it and buy a few beefy GPUs.

All those cores are clocked at ~1GHz and they're not even Haswell i3 cores. It's a piece of shit anon, accept it.

Wait, why didn't they use haswell cores? Is intel fucking trolling us?

>>51922903
You don't seem to understand the gravity of the problem that intel used airmont cores.
Wait so airmont cores have the same performance as AMD FX CPUs?
>>51922855
I'd imagine it to be a test run to see how many cores they can fit inside one unit
Once you think about it, this is 72 individual cores inside a single package, even if one core is 2W that makes the whole thing a whopping 72x2=144W CPU
Haswell cores consume even more, I'm not sure if a haswell core based CPU is even possible
>>51922935
You don't seem to understand what it's supposed to be used for either. It could be fucking ARM cores and it'd handle it's job relatively well.
>>51922731
>being completely retarded
>>51922974
the i7 4960x has a tdp of 130 watts. Even if you overclock it, it won't use more than 200 watts on load.
Knights landing is a fucking joke. It'll actually have a tdp of 200 watts most likely too.
>>51922974
>mfw one Haswell core eats like 13-15W
I'd love to see someone make a Haswell based 72 core CPU, I would just love to
>>51923017
How is he wrong? Airmont cores are a piece of shit, that's why they put 4 physical cores on the z8700 instead of just 2. 72 airmont cores most likely have the same performance if not less as the i7 5960x (8 haswell cores).
>>51923062
It wouldn't actually be that bad. A haswell core clocked at 1 ghz would probably eat less than 4 watts.
>>51923091
You're still missing the point you bumbling fucking moron. Raw power isn't what these are for, it's parallel processing. 288 meh cores > 8 good cores for that.
>>51923136
>cores
*threads
>>51923091
If the z8700 benchmark is extrapolated to 72 cores, it's more than double the i7 score. Of course it's not an accurate comparison and the usage cases are different, but it'll probably still be more powerful.
>>51923017
So 72 1ghz airmont cores would translate to less than 36 1ghz haswell i3 cores? It's that bad?

Transforms, motion analysis and things like that may be very easy on the GPU, but ultimately you need to arrange your data into a sequence of blocks or whatever and apply inter-block prediction, entropy coding, etc.
When each decision you make affects many later ones a GPU (with its high communication latency) is not going to be very useful at all; what you want is a fast single core or a specialized DSP.
>>51923692
by that logic so does your vanilla Skylake processor, because it has an integrated GPU.
>>51923741
sad but true. although imagine what kind of sweeet raytraced game you could write for that processor.
>>51924076
raytracers don't give a shit about whether or not you use FP, so obviously if FP is an option you choose FP.
Raytracers should go GPU all the way.
>>51924076
It would run just as fast if not faster on an i7-5960x which only costs 1 grand too.

Because Atom cores dont have the nifty hardware needed that help reduce pipeline bubbles and increase instruction level parallelism, so there's alot of holes in the execution pipeline.
Adding in 4-way hyperthreading (in theory) allows for much higher hardware utilization w/o a significant increase in power consumption or thermals.

To all the anons shitting on atom, at 72 cores the focus is obviously on multithreaded. Sure, something with 72 current gen high end 17 cores would be better, but perhaps unfeasible.
If someone knows how to program for 72 *4 threads then they're not gonna care each one isn't at (2015 intel ipc) 3GHz.

The point is knights landing is severely overpriced compared to the i7 5960X ($1000) and might even worse multi-core performance compared to it. I would pay $1000 for this chip max.
>>51928755
The problem here is price, this thing is massively overpriced and most likely was worse multi-core performance compared to the i7-5960x. Also this thing might consume more power than the i7 I mentioned because it has to feed 72 independent cores instead of just 8.
>>51923718
How can it benefit you? Like just having one in your PC?
>>51923718
Except Knights Landing is perfectly capable of acting as a normal, standalone CPU running an OS. Theres a couple images floating around of a prototype Knights Landing system running windows.
>>51928967
It can't. You need to program your code to take advantage of the 288 threads and not everything can run on 288 threads efficiently. It would be better to just build two desktops with i7-5960Xs for 3K. You get twice the performance (maybe more) of knights landing for the same price and you don't have to deal with efficiently using 288 threads.
I'd rather buy 3000$ worth of either Raspi or Xboxes and build a real beowulf cluster.

Yup. Actually, you think it would work in an older system? With like 2 cores/threads?
Alright /g/entooman, hypothetical question here.
Let's say you're in the market for a shitload of parallel processing power, and you have $3000 to spend. Do you:
>Buy one of these and use the software they make for it and following the proprietary standards they give you, basically limiting any options for the future of your computing needs

>Buy 500 RPI Zeros and use the remaining money on cabling to beowolf them with a linux distro centered around clustering. Future upgrades can be any ARM processor or virtualized ARM processor hooked into the cluster on the fly
Intel built a pointless machine designed for people who are too lazy or stupid to build decent hardware for their needs.
>>51929429
>>51929449
I think the pipes are ~17 stages deep, and 4-wide, if I'm interpreting the anandtech article on silvermont correctly.
>>51929449
Its probably a balanced mix of both, with some ILP extraction as part of the base architecture (Silvermont), but with some of the shinier stuff cut out and replaced with 4-way hyperthreading to keep a cap on power consumption and die size. A curry-ccf article estimated a die size at ~720mm^2
>>51929501
Knights Landing can natively run an OS if its in one of the socketed variants. See >>51929243
>>51922434
then he takes it apart and makes it his private NAS
>>51929530
Correction: 13-17 stages deep, 2 wide.
>>51929571
Ok yeah I stand by 4-way SMT being stupid.
>>51929677
It might make sense here though as they wanted to keep utilization as high as possible with so much of the ILP extraction and other goodies removed. Less ILP, a deep pipe, and more holes in the pipe makes it a bit of a bastard to keep it full, which was the entire point of HT in the first place: keep the pipe packed while other threads are waiting.
Sure, theres gonna be a performance penalty with running that many threads on a single core as diminishing returns hits with all the grace of a rocket propelled sledgehammer, but at least intel didnt go full retard like IBM did stuffing 8 threads on a single core on POWER8.
>>51922173
I'd sell that garbage and then save up or borrow enough money so that I could buy myself a nice Mac. Lol for the price of one of these so-called Beowulf clusters you'd think it would have an app store, run good software like Photoshop, Final Cut Pro, or Boot camp, and make you more popular. I'm an anarchist so being accepted and liked by my peers is highly crucial. It's like how can you expect to fix the world when you can't even fit in with your friends properly?
It's also great to know that my parents actually love me, and want only the very best for me. My ex-boyfriend's parents didn't even care enough about him to even buy him a fully working Windows PC, and he actually had to put it together like some sort of mechanic. I'm not racist or anything but it's obvious to me that African-Americans just don't love their sons like white people do.

ARM has lower (of all currently architecture) performance/Watt efficiency, RPI use a ancient 32-bit ARM11 (armv6) microarchitecture, better get an something with aarch64(armv8) such pine64, HiKey, Dragonboard 410C, etc. but you can just buy an x86 or cheap sparc64 and get much better performance.

That's not what I meant, I remember reading about them making something similar to what OP describes a number of years ago, and I was curious whether this was a continuation of that idea, because I was under the impression that particular project had been scrapped.
