Back in the Clarksfield days, Intel had the IGP and the memory controller on a separate die as something of a compromise.

HBM2 is probably the first time they've had a memory solution with enough speed and density to make a decent IGP practical with a multi-die setup that also didn't compromise the CPU performance.
what if they used a bigger cache L4? that would probably solve the problem partially

Broadwell C CPUs could have gotten better performance if probably they used current KBL iGPU?

later intel could use HMC(DDR5) based memory if bandwidth is a requirement

Yes and yes, but the L4 was there primarily to aid the GPU and was as separate eDRAM die of low density...there are 4GiB HBM2 stacks in production and they don't take up any more room than Intel's 128MiB eDRAM dies and offer better bandwidth.

Nothing preventing Intel from using an on package HBM stack as an L4 either.

HMC is less mature and has lower adoption. With JEDEC backing HBM and Intel not part of the HMC consortium, HBM is likely the way Intel will go...as this article suggests.

Big different between EMIB and Silicon inteposer Is Bandwidth.with EMIB , You have less bandwidth that is enough for iGPU.I really don't think AMD APU will benefit from high bandwidth more than 250GB/s.I believe AMD APU with 12 CU won't be more saturated above 250GB/s.limited always exists.

I am only interested in IPC and that doesnt show provide any indication that Intel is moving away from +5% IPC every year.


I have enough of the useless iGPU nonsense. Looks like Zen didnt give them a good wake up call.

i don't think zen gave them one at all
i don't see why zen would give them pause, even

As much as I hate to say it, yes I think you're right. Many of the non enthusiast people I've spoken with would still prefer to go with a lower performing Intel system because of trust in the brand. Here's to hoping that this new tech will be a larger than normal step forward.

Was hoping for a huge low latency on-die cache for CPU cores, oh well one can dream.

That might come later with jedec specifications.

i personally have gone with intel because it is better at doing the thing i like to do, which is play games at high fps at a high (overclocked) clock speed
unfortunately the "bonus cores" model of zen has hamstrung zen in basically every way. it's bulldozer light, of sorts
