Question Intel Q2: 7 nm in bad shape

Those unfamiliar with the Intel organization may be confused, because the title of "Principal Engineer" is often handed out for non-technical contributions. Francois Piednol was never an Intel Engineer in any technical sense. Piednol was a marketing employee in the retail/direct-to-consumer...

Discussion Intel current and future Lakes & Rapids thread

Tiger Lake, Willow Cove, whatever you want to call it. It could be a great product if Intel cared enough to make desktop CPUs, but all they care about is laptop. Fact is, only AMD makes a desktop-first CPU (RyZen, lots of cores, no iGPU crap). If Tiger Lake is so great, why won't Intel make...

3DPM is a useless benchmark that does nothing but division. CNL/ICL has some special acceleration for divide. It's not happening... Next two years of roadmap is already confirmed, and it's Skylake Skylake Skylake. Only AMD releases desktop processors today, whereas Intel dumps rejected laptop...

Massive security hole in CPU's incoming?Official Meltdown/Spectre Discussion Thread

Yet again, AMD not affected, but sure, 9% performance decrease will surely not be "noticeable." Ryzen was tied with Intel at launch, and now between Meltdown, Spectre, L1TF, and this new Zombie(!) exploit, Ryzen is 30% higher IPC than Coffee or whatever Lake.

Discussion Intel current and future Lakes & Rapids thread

To everyone complaining about the "missing" 10 nm desktop parts, how can you still be unaware that Intel couldn't give a rat's ass about desktop? The last time Intel made a desktop CPU was the Pentium 4 (which was terrible). Everything since then has been an overclocked laptop processor. The...

【Maxon】Cinebench R20 Benchmark Thread

Even though Maxon claims that R20 is an "AVX" application, there are no 256-bit instructions in it. And that's great news for Zen and Zen2! This is the most costly function (ray-triangle intersection). It contains some FMAs, which theoretically penalize Zen, but the ratio of FMA to load is too...

Discussion Intel current and future Lakes & Rapids thread

Pretty much goes to show that Ice Lake is a paper product. They can barely produce enough for two super-niche products, and meanwhile the bread and butter is still on the "well-aged" 14 nm variants (Whiskey, Coffee, Vodka...). The "improving" 10 nm yields are a slight of hand, and meanwhile we...

Coffeelake thread, benchmarks, reviews, input, everything.

As I noted, Intel makes no effort to provide tight bounds on the power consumption of "desktop" (overclocked laptop) parts. If you try this on mobile or server, you will see it approach the base frequency, with maybe 2-3 bins of margin on most parts. Actually, if you look at the reviews for the...

Coffeelake thread, benchmarks, reviews, input, everything.

Of course the base frequency exists. TDP is the worst-case non-AVX power at the base frequency, which directly implies that the base frequency is the minimum frequency the processor runs at when limited to TDP by PL1. If you run a power virus, I'm sure you'll see the frequency approach base...

Coffeelake thread, benchmarks, reviews, input, everything.

The "leak" could very well be fake, but the TDP is defined for the base frequency, which is also suspect. The turbo frequency is not constrained by TDP at all, but only by the VR specification (ICCmax) and circuit timing. So we'll see "95 W" chips that run at 300-500 W out of box, similar to...

Coffeelake thread, benchmarks, reviews, input, everything.

If you search for AIDA64 screenshots, you will see that L3 latency essentially did not change when going from the 7700K to the 8700K. At worst, Broadwell-EP AIDA64 screenshots show 16 ns latency on LCC chips at the factory 2.8 GHz frequency. Overclocked screenshots show the latency back down to...

Intel Confirms Skylake Xeon D in Early 2018

How would Cannonlake-DE be any more interesting than Skylake-DE? Broadwell-DE was interesting because it integrated a higher level of connectivity than was available in Grantley in a compact and low-cost platform. Skylake-DE is disappointing because its connectivity capabilities were already...

Intel Confirms Skylake Xeon D in Early 2018

Let us look at the leading "cloud" provider, Amazon. Who knows, maybe you work for Amazon, since you claim to have so much "cloud" knowledge. Every month, they announce a new, bigger, faster, etc. machine shape. If nobody wants anything but 1-core oversubscribed commodity hosting, why is Amazon...

Intel Confirms Skylake Xeon D in Early 2018

No? If you have 4x 8 core nodes, you can only fit 4x 5 core VMs. Sure, you can also pack 4x 3 core VMs to make the difference, but at the margins your efficiency will go down, because you can not always find the right mix of jobs. Before you try to hand-wave this away by claiming most VMs are...

Intel Confirms Skylake Xeon D in Early 2018

It sounds like you are talking about the "ultracheap" segment. The fact of the matter is, as soon as you need a 5 or more core VM, you have serious packing issues on EPYC which reduce the value proposition. This is on top of the fact that Skylake-SP is dirt cheap for "cloud" companies, but I am...

Intel Confirms Skylake Xeon D in Early 2018

That is actually not clear at all. Leaks have shown that Zen2 will reach 16 cores/die and 64 cores/package, but the Icelake leaks only reveal up to 38 cores. It may well be that second-generation EPYCs consume much more power than the current SKUs, but increased density has a value of its own...

Intel Confirms Skylake Xeon D in Early 2018

This is true, but we are talking about tens of dollars of savings here for any significant customer. Given the expanded TDP of the D-2100, the main advantage remaining is physical size. This does matter on the "edge," but it is not going to be a dealbreaker if EPYC were already competitive. Even...

Intel Confirms Skylake Xeon D in Early 2018

I do not see Skylake-DE making much difference either way in terms of EPYC competitiveness. The new generation of Xeon D is not exactly a revolutionary product the way the original Xeon D was. Given that the new processors are just Skylake-SP with on-package PCH, the only real difference is form...

Intel Confirms Skylake Xeon D in Early 2018

EPYC has only 42 GB/s bandwidth per domain. Having "more" bandwidth through 8-way NUMA is meaningless if that bandwidth is unavailable when it is needed. The most important server workload, the database, performs exceedingly poorly on EPYC. The Anandtech site benchmarks are a full of obsolete...
