AMD Working on 16-Core Processor with Integrated PCI Express 3.0 Controller
In a document published by AMD some new information surfaced. It seems that AMD is working on a new 16-core processor, and that is a true 16 cores, thus not a an 12 CPU cores and 4 GPU cores combo or anything. And no it is not the existing AMD Opteron 6200 Series either. This is something new. Obviously such a processor would see a launch in the server segment first hence we think the processor will be an Opteron. The developer documents list the 16-core unit under Family 15h Models 30h – 3fh.
This 16-core processor will have a full uncore, which is terminology for the functions of a microprocessor that are not in the Core like QPI controllers, L3 cache, on-die memory controller and so on. The PCI Express and SPI are typically merged into the the chipset, not the Uncore.
There is no confirmed information available on what technology or family (Piledriver etc) the CPU cores are architectured but the Family 15h Models 30h – 3fh indicate SteamRoller CPU cores as previously released in AMD's Kaveri APUs; yet in this case with eight dual-core processor modules on a single die. Have a peek at the document right here.

Assuming this is gunna be a monolithic die for server applications, though if they did export do desktop...

By the time they integrate PCI-E 3.0, Intel will be on 4.0 lol.

I would hope so. As far as I'm aware, we haven't even saturated 2.0 yet. Aside from some SSDs, I don't really understand the point of releasing PCIe 3.0.
AMD already has several 16 core Opterons. I'm guessing their current generation is Steamroller based, and I figure this new 16 core will also only be an Opteron. AMD has stated before they're not targeting the high-end/enthusiast desktop PC market anymore and that's exactly what a 16 core would be classified as. I don't see a reason for a 16 core entering the desktop market anyway - most people still can't put good use to an i7. But, Opterons are still relatively cheap. You could probably make a pretty good desktop computer out of an Opteron system as long as you expect the motherboard you get likely lack Crossfire/SLi support, built-in audio, and a slew of USB ports.

Exactly. The current 16-core Opterons are a bit like the Pentium-D and Core2-Quads, though, dual 8-core Bulldozer/Piledriver dies on one chip, so having this as a monolithic CPU would be a big step up for AMD. Saying that, looking at Kaveri on the new 28 nm CPU has really shrunk the die size down quite a bit from what you'd expect, so assuming it'd be on the same process is reasonable. We might even see something that can complete with Haswell-E's 8-core if we're lucky. If I were aiming for a cheap server though, it would be AMD based, the intel Xeons are horrendously expensive, Opterons, not so much.

Mantle + 16 core gaming can be good. Crop some L3, add 4 more cores(which means more L1(and even L2)), add two more channels for memory, add some pipeline depth, decrease frequency and increase efficiency, increase working temperature so it works okay even over 75°C, make L2 or L3 caches addressable by APIs like CUDA and OPENCL and .... so better game physics, all these can be even better.

I think you mean releasing PCIe 4.0. We've had 3.0 for a few years now, and I'm running 3.0 x8/x8 in SLI now. Intel has plans on releasing 4.0 this year or next. I thought I read somewhere by 2015 at the latest.
I saw 780's running in a x8/x8 2.0 rig and were slower in benches and gaming.
4.0 may be needed for the super enthusiasts looking to push all that bandwidth. There are already bigger and badder cards than Maxwell planned. I myself am not upgrading though.

PCI Express 4 ??

There is still no graphics card can bottleneck a PCI-E x16 v2.0 then why you need v4 ??
I think you dont have any idea about PCI-E and its bandwidth......

apparently skylake is getting pci-e 4.0
since AMD has removed the CF bridge for R9 an made them bridgeless apparently they can now saturate pci-e 3.0 @ 16x since they talk over the pci-e now

...Things might change this year, but I won't be upgrading anything because I expect Mantle to supplement my CPU well enough that I'll be able to ride my i7 920 (& R9 290) for two more years

I remember reading some benches a year ago about PCI-e 2.0 vs 3.0, and if memory serves me right, there was only a 3% degradation when using 2.0 (instead of 3.0).

Ummmm...huh? L1, L2 and L3 aren't addressable by APIs because it would cause problems for the processor.
Increasing pipeline depth would be very bad. Decreasing frequency, while increasing pipeline depth would be suicide for AMD. To increase efficiency, you have to shorten the pipeline.
AMD can't do anything that affects CUDA because they have no rights to it...also, allowing CUDA to access cache, wouldn't improve PhysX in the least as the system would be too unstable to be usable.

Why increasing the pipeline depth cannot increase instructions per cycle?
How can we increase total performance of CPU then? Increasing clock frequency versus increasing IPC?. Which one is more future-proof? Which one is more efficient in terms of "instructions per Joule"?

It would be good if available for desktop and not costing an arm, leg, and left teste. I'm guessing Excavator based? Since it would make sense to be on 20 nm or even 16/14 nm.
