[IT World] Intel cancels Broadwell-C **Article corrected to say it meant Skylake-C**

[Vesku]

Intel did confirm to me that the part was cancelled but would not give an official reason. It's a shame because that chip had all the makings of a big seller. What remains to be seen is whether eDRAM will be used again and if there will be a Skylake-C.

IMO, one of the effects of lack of competition. When a company competes with only itself it has a lot more leeway to do things like this.

They're probably holding desktop eDRAM back until Kabylake, to make the refresh a bit more enticing, and also to kick AMD where it hurts when Zen eventually shows up.

Don't we have the Broadwell 5xxxC chips already released in other countries, except for the US?

 

[cbn]

I think the CPU part is too strong relative to the iGPU.

Most spending that kind of money would pair with dGPU.

A better balanced chip would be a dual core GT3.75e for desktop. This made from die harvested 4C GT4 dies.

Yes,they are available, here in europe at least.

Yield is so bad they need to cut back on die sizes.

4C GT3 Broadwell die is only 169mm2.

Considering how poor Skylake-K's yield looks like, the extra 30% or so Broadwell-C would only make things worse.

 

[Vesku]

I don't think it would have reached this stage of release, i.e. partial, if it was all about yields. They would have just gone straight to Skylake or released a desktop broadwell without L4.

Xeon-D was 160mm2 on 14nm and that launched back in March 2015.

So I think something else is going on.

Most likely demand for a low end iGPU like GT3e paired with powerful quad core is not strong enough on desktop.

 

[jpiniero]

Xeon-D was 160mm2 on 14nm and that launched back in March 2015.

Xeon-D has a cut version available though (4 cores), so salvaging would be much easier. Plus it's on the low power process and low clock speeds.

Intel never got a chance to see how the sales would be versus something like the 6700K.

 

[AtenRa]

The fact that Intel doesnt want an inside competitor to the new Skylake Platform (chipsets) and CPUs has occurred to anyone ??

Why sell a bigger CPU die (Broadwell-C) at lower margins when you can sell both a new chipset (Socket 1151) and a smaller CPU die (Skylake) at higher margins (no Heat-Sink).

 

[mikk]

Intel cancels Broadwell-C sounds odd considering that in my country this CPU is widely available, although it doesn't seem to be selling that well. Skylake-K sells much better. I think there is no demand for Broadwell-C, maybe that's why Intel doesn't plan 4+4e SKL for LGA.

Yeah, that is a problem of the 4C GT3 Broadwell die. How do the potential harvested die variants (4C GT2.75e, 2C GT 2.75e) fit various niches?

This, in contrast, to a high volume 4C GT4e Skylake or Kabylake die where I think there should be good potential for using harvested parts like 4C GT3.75e at 45w, 28w, 15w and maybe even 10w levels. Then the least desirable dies (2C GT3.75e) become the 65W (or greater) BGA desktop processors.

Its selling all over Europe and Asia. Nor is its product status changed.

Honestly, Broadwell-C is a niche product that is eclipsed by Skylake-K.

With Skylake-K, you get a newer platform with a LOT of extra goodies, and a newer CPU core at a higher base frequency.

You give up the eDRAM, but I don't think most buyers would care.

 

[ShintaiDK]

One also has to remember that Broadwell-C will slow down if computational challenged. The 3.3Ghz+eDRAM only works as long as the main bottleneck is somewhere else.

It's just not as good a product as 6700K, plain and simple. Broadwell-C is looking like a failed attempt on Intel's part to cobble together "something" to try to sell to desktop buyers because its management made the silly decision to not invest in rolling out mainstream desktop-oriented Broadwell chips.

However, thanks to the lousy 14nm yield situation as well as the fact that this part was probably very low as far as Intel's priorities go, the thing ended up so badly delayed to the point that it was made obsolete before it hit the shelves by Skylake.

I think you forget IGP and 65W. While we can argue if LGA or BGA matters. Its still a product with its place. A BGA version with 4+4e will be its successor.

 

[jpiniero]

There's no reason to recall the product. Intel will just sell the remaining inventory plus any in process. They just won't make any more.

If anything, the 6700K was cobbled together at the last second. Intel wasn't even going to sell Skylake-K and was going to roll with just Broadwell-C to push the high perf graphics and compute. That's why there is no fan because there was no time to validate one. It was only going to be the locked quads.

Skylake-K have been on the roadmaps for ages.

I doubt it. From The Tech Report just a month ago:

As for the Core i7-5775C, Intel says it's experiencing strong demand for that chip, as well, and that we should expect desktop Broadwell to become more widely available "as Q3 progresses."

It also doesn't make sense to cancel it and keep Xeon E3-1200 v4 on sale.
And Apple is expected to use this chips in their next iMacs.

Kind of have a feeling that it's going to get cancelled and that Broadwell-E/EP/EX won't really be available until June or cancelled entirely. Intel's had 14 nm products since last year and they are still having real bad yield problems for anything not tiny and Broadwell-C's cancellation is a signal of that. It's not panic time but Intel needs to get more conservative about die size.

It does sound like a made up article. No surprise.

I have a feeling the freelancer writer simply looked at US stock and then made his conclusion that way.

If that is true, then I don't see Intel being able to increase iGPU size in the near future.

So maybe GT4e becomes the max for a while (allowing Intel to integrate lower power logic (southbridge, etc) on die) before advanced process tech allows more high power xtors.
