They are used in OEM systems however. Although OEMs tend to limit motherboard features.

I'd be more concerned about bugs with the first generation motherboards than I would the CPU.
As of this morning you can't buy an AM4 motherboard off newegg. Maybe I'm missing something but to me that doesn't exactly spell out widespread adoption and testing.
Hoping for the best.
If the Ryzen dies are indeed smaller (or even the same saize) as 4C8T Ivy Bridge or later, then that would rule out a soldered IHS. It will be interesting to see how close AMD are willing to place the IHS bottom to the die top: Intel's 0.06mm is conservative, trading off thermal performance for robustness. If AMD go for a finer tolerance they may gain some thermal headroom, at the risk of damage from direct die contact. Personally I'd expect the gap to if anything be slightly larger, as AMD's stock thermal solution requires the heatsink to be clamped on one side and then the other (giving a huge off-axis load to the IHS), while the LGA11xx design progressively tightens around the corners (as long as you follow the instructions).Also revealed that Ryzen chips dies are smaller then skylake dies.

"Its also worth pointing out that Intel has a double precision IPC of 16 FLOPs per Clock with Skylake as well as 2x 256 bit FMA whereas Zen only has 8 FLOPs per clock and 2* 128 bit FMA."
This disappoints me:

I wouldn't call that competitive. I really, really wanted AMD to have good floating point power and no glaring weaknesses, but here we go....

Using info from middle of last year.
That doesn't make it wrong tho since those they copied from is correct.

You are reading into it wrong.That image makes zen look it'll be half as fast as skylake

Why even post this? Can you guys at least keep your bickering to one thread and not just bash on each other in every new Ryzen thread that pops up?Anything to attempt to put AMD in a bad light, eh? No surprise there though, this is par for the course.
AMD isn't an embattled politician, an oppressed historical figure, a refugee, or an underdog baseball team, they're not David and intel isn't Goliath. Why anyone is emotionally attached to AMD or intel makes no sense to me. They make chips and sell them to you. You don't get a pat on the back. You don't get a personal letter thanking you. They each just try to do things to stay relevant and appease shareholders and stay in business. So why the hell are people emotionally invested in the underdog story of AMD? Just choose whatever works for you and your budget and quit trying to convince someone if they choose intel they should be choosing AMD and vice versa.Anything to attempt to put AMD in a bad light, eh? No surprise there though, this is par for the course.

In 256bit AVX/FMA loads? Yes. For everything else? No.
That's all you can conclude from it.
The TIM in Ivy Bridge and onward is just fine, it's the clearance gap between the die and the IHS that causes the 'issue':It doesn't even need to be soldered, they could just use a better TIM.
[...]the only functional differences in these two test conditions is the CPU TIM. Notice that the Intel stock CPU TIM outperforms the NT-H1 replacement TIM once the CPU-to-IHS gap is identical
Right, the AVX throughput is half that of Skylake. But how many consumer or server applications need that kind of AVX throughput? Only h.265 encoding (with the much larger blocks) and rendering/machine learning really benefit.
But the normal integer/float throughput is more competitive, and you get more cores at a lower power point as a result.
Basically, this is what Bulldozer SHOULD have been: not a clunky shared FPU/front-end unit, but instead a smaller split 2x128-bit dedicated FPU per-core, using HT to get the most out of it.
That load/store bandwidth advantage only comes into play when you have something embarrassingly parallelizable, and they're hoping you'll use a GPU for that. We'll have to wait and see how much this harms performance, but I'm betting it will be mostly transparent in real-world (like the Pentium Kaby Lake with AVX disabled is similar to i3 in most games, office and pro applications).
The most important thing you can conclude from that diagram is HOW CLOSE in performance Haswell is to Sandy Bridge, even though one has twice the bandwidth.
Because NERD.
IPC wise Zen is legitimately strong even told that it takes a highly overclocked 2600K to keep up.
They are comparing mobile SKUs, maybe even ultra mobile SKUs, in which case Intel's words are most likely legitimate.Intel also says that Kaby lake is 15% faster than Sky lake. I think whoever is in charge of metrics has been drinking a little. I wouldn't invest too much into this.
You are not wrong. CPU's often have erratum that can be pretty scary but microcode updates and common BIOS workarounds employed by all manufacturers can usually resolve those things. What's more difficult to deal with are integrated features, chipset level problems and the various firmware(s) that come together on a motherboard.
If this is the case, given anecdotally Intel hasn't had a lot of luck convincing people with overclocked 2600K's to upgrade to their latest and greatest, what's going to be the draw here to get those people to move away from their 5-6 year old processors, let alone those released since then? I know chipset features are often cited as reason to, but that applies to both AMD and Intel so... extra cores? Lower pricing? Those looking for a means to stick it to Intel, "side-grade" or not? If its primarily going draw those that are already brand loyal, not sure that's going to help build up market share.
15% with clockspeed * (IPC/SmT)Intel announcing new CPUs and already promising Canon Lake to be 15% faster (in one bench at least) truly shows that panic is in order. When Ryzen isn't even out yet and they are already scrambling is evidence in itself. I have never seen intel trying to move so quick on something lol..
In certain workloads***.M
15% with clockspeed * (IPC/SmT)
It's probably like how Kaby Lake is faster than Skylake in certain media related things but for general purpose computing the only thing that makes it faster is the clock bump
According to Intel's marketing, Kaby Lake is 20% faster then Skylake, so Canon Lake will be an even more minuscule performance improvement:
