@ZeDestructor you are probably right looking at the bottom side again transistor array screams single die

 

[alucasa]

Been watching prices. You can pick up a 6800K for $380 right now...

My current CPU (which I picked off ebay for 350 usd) beats hell out of 6800k for my purpose (rendering).

I was just going off the fact that the full 72-core KNL chip is a single die.

(the 4 empty pads on the package are for HMC stacks (Intel+Micron's competitor to HBM))

I would rather love for that to be true just so we could see what Intel has been hiding behind closed doors. Guaranteed those clowns have the next great thing ready and waiting for a reason to actually release it.

I don't think Intel is hiding very much behind their doors for any instructions that aren't AVX1 or newer. The reality is that they've already tuned base x86+MMX+SSE to the absolute limit, and that's why the improvements have stopped.

Is kind of unrealistic. I mean they are pumping billions each year for R&D, surely they must have done something in the past 5 years; I don't want to believe that all those billions just got to waste...

 

[huguberhart]

Looks like Pentium Pro was larger still... such a good memories. My first dual board and NT4...

Do you remember Project Keifer? The video seems to be gone, but it was crazy, with the manufacturing process that these processors had. The efficiency helped get to these - just 5 years later...

There's always a hard cap on how much you can speed up an instruction before clockspeed or power becomes the limiting factor. Clockspeed itself is limited by power and reliability, so the overall limiting is power² and reliability. That's pretty much where Intel is now: right at the limit of power and reliability for the existing old instructions. What you instead see is much more R&D spent in making shiny new instructions (AVX in particular for example) because that's much more feasible and effective. And before you say games are never gonna use em, look again, cause SSE4.1 is gradually becoming the base requirement, while really good devs (like Grinding Gear Games) are using AVX already!

Another thing that you're ignoring is that the R&D billions also includes SSDs, networking, switches, wireless, GPUs, co-processors (Xeon Phi, QuickAssist, etc.), software, I/O (PCIe, DMI, QPI/UPI, OmniPath, protocols like NVMe) and fabrication tech, not just CPU cores.

 

[xorbe]

r&d goes to drm encryption probably, yay

 

[Aquinus]

Dat socket... 3647 pins is a lot of pins. That can't all be power delivery. There must be a lot more of other things like DRAM channels, PCI-E lanes, or QuickPath.

 

[ratirt]

Knowing that AMD has increased the DRAM channels and PCI-E lanes as well ( I think) Intel does the same. It also goes with the core count. Now it will be 32 for intel too which was 22-28 as I remember correctly. Now it has changed. That's good. The question is here now if Intel tries to reach same performance AMD's Napels or just the core count as a counter proposal for the server market.

Oh I'm sure it does, I was just commenting on the fact that it looks like Broadwell-E CPUs are being cut in price aggressively already.

I'm sure they have something good in a back room.

Yeah, a 10ghz pentium 4

They blew all the cpu money on fabs, which is why they're slowing it down. There's no extra cash to be made when upgrading (and wafers) cost more than the profits from increased dies per wafer.

I'm pretty sure Zen is a lot better than you think it is, but you just love to crap on anything AMD.

They must, I mean they dropped, or will be - unless I misunderstood things, 6 core on us peasants recently and now this behemoth. They must be preparing for something, why else would they make those moves? It aint out of the goodness of their heart/s LoLoL

 

[Nordic]

I don't think intel has any magical architecture or instruction set that they are hiding. I don't think it is in their best interest to hold on to something like that.

I do think intel is holding back in more obvious ways. I think if intel had actual competition we would start seeing overclocking enabled across the line. We might also see features from the HEDT platform come into the mainstream platform. Those could be more cores, more pci lanes, or other.

Not sure about that one. I don't think too many people overclock their PC in the face of number of CPUs sold... what are we, like 1% maybe? .1%? I really don't think they're trying to bleed out enthusiasts when we don't matter in the grand scheme of things.

...Buuuuut, it's rather strange to see locked, unoverclockable chips and "k" unlocked, overclocker friendly chips appear right after Intel gained dominance in CPU performance. But even Sandy and Ivy were overclockable +400MHz, at least. After that, they totally shut it down with Haswell (unless, of course, you bought the shiny K edition). Given the timing and the way they cut overclocking down to crap, and then nothing at all, it seems rather deliberate.

1% with much higher margins, though. Crooks are going to make profit if it's worth doing. OEMs get CPUs for dirt, comparatively.

Yeah like Iris Pro Ultra with 64 Gb of EDRAM coming in at 4000 dollars a pop, and performing like an RX480.

Or an IoT device nobody knows they want yet.

No honestly, it is very clear from the past five years and Intel's movements that they're still searching for the next big thing and haven't found it. They do some hardware, they do some IoT, some VR, and none of it really sticks. They did ultrabook and all we can say about that is that they're flat, weak and overpriced laptops. They retried GPU and all they could provide was a Broadwell proc that never really got traction and is mainly found in gaming systems WITH a dedicated GPU (the irony), in the meantime the regular CPUs still have slow IGP and it won't be changing anytime soon.

I don't think it would be the first thing they would use to be competitive, but if faced with enough competition I am sure they would bring overclocking out across the line.

Correct. We already know that Purley is pushing 6-channel DDR4, and some leaks from OCP suggest 44+ PCIe lanes per chip. On top of that, QPI is being replaced by UPI, and they're probably fully pinning-out all UPI links and all PCIe this time round, unlike Socket R where the third QPI being populated meat eating 8 PCIe lanes (hence LGA2011-1). The new OmniPath interconnect on the other hand will be on a lip that extends directly from the package past the socket area.

I don't think it would be the first thing they would use to be competitive, but if faced with enough competition I am sure they would bring overclocking out across the line.

I highly doubt that Intel will open up overclocking more than the rumoured unlocked KBL i3. TBH, I expect AMD to also lock down overclocking in this round for the higher-end chips.
