Refresh Done Right? Intel Comet Lake Packs Up to 10 Cores

[coreboot], an open source project to replace the BIOS and UEFI, has some vital information on Comet Lakes. According to the Github page, Comet Lake-U (CML-U) processors, which are primarily aimed at laptops, carry up to six cores, while the Comet Lake-H (CFL-H) and Comet Lake-S (CMT-S) chips feature up to 10 cores.

Rumors on the street are that AMD's forthcoming Ryzen 3000-series desktop processors could purportedly pack a whopping 16 cores on a single chip. During AMD's presentation at the CES 2019 tech show in January, an eight-core, 16-thread Ryzen 3000-series chip was trading blows with Intel's Core i9-9900K, which could have pressured the Santa Clara chipmaker to cranking Comet Lake's core count to 10 cores for safe measure.

Intel is expected to launch its Comet Lake processors around the middle of the year. It's possible Intel could announce the chips at Computex 2019, which starts May 28.

AMD Announces Radeon VII GPU, Teases Third-Generation Ryzen CPU 15 comments

At AMD's CES 2019 keynote, CEO Lisa Su revealed the Radeon VII, a $700 GPU built on TSMC's "7nm" process. The GPU should have around the same performance and price as Nvidia's already-released RTX 2080. While it does not have any dedicated ray-tracing capabilities, it includes 16 GB of High Bandwidth Memory.

Nvidia's CEO has trashed his competitor's new GPU, calling it "underwhelming" and "lousy". Meanwhile, Nvidia has announced that it will support Adaptive Sync, the standardized version of AMD's FreeSync dynamic refresh rate and anti-screen tearing technology. Lisa Su also says that AMD is working on supporting ray tracing in future GPUs, but that the ecosystem is not ready yet.

Su also showed off a third-generation Ryzen CPU at the CES keynote, but did not announce a release date or lineup details. Like the second generation of Epyc server CPUs, the new Ryzen CPUs will be primarily built on TSMC's "7nm" process, but will include a "14nm" GlobalFoundries I/O part that includes the memory controllers and PCIe lanes. The CPUs will support PCIe 4.0.

The Ryzen 3000-series ("Matisse") should provide a roughly 15% single-threaded performance increase while significantly lowering power consumption. However, it has been speculated that the chips could include up to 16 cores or 8 cores with a separate graphics chiplet. AMD has denied that there will be a variant with integrated graphics, but Lisa Su has left the door open for 12- or 16-core versions of Ryzen, saying that "There is some extra room on that package, and I think you might expect we'll have more than eight cores". Here's "that package".

AMD and Intel at Computex 2019: First Ryzen 3000-Series CPUs and Navi GPU Announced 20 comments

At Computex 2019 in Taipei, AMD CEO Lisa Su gave a keynote presentation announcing the first "7nm" Navi GPU and Ryzen 3000-series CPUs. All of the products will support PCI Express 4.0.

Contrary to recent reports, AMD says that the Navi microarchitecture is not based on Graphics Core Next (GCN), but rather a new "RDNA" macroarchitecture ('R' for Radeon), although the extent of the difference is not clear. There is also no conflict with Nvidia's naming scheme; the 5000-series naming is a reference to the company's 50th anniversary.

AMD claims that Navi GPUs will have 25% better performance/clock and 50% better performance/Watt vs. Vega GPUs. AMD Radeon RX 5700 is the first "7nm" Navi GPU to be announced. It was compared with Nvidia's GeForce RTX 2070, with the RX 5700 outperforming the RTX 2070 by 10% in the AMD-favorable game Strange Brigade. Pricing and other launch details will be revealed on June 10.

AMD also announced the first five Ryzen 3000-series CPUs, all of which will be released on July 7:

CPUCores / ThreadsFrequencyTDPPrice
Ryzen 9 3900X12 / 243.8 - 4.6 GHz105 W$499
Ryzen 7 3800X8 / 163.9 - 4.5 GHz105 W$399
Ryzen 7 3700X8 / 163.6 - 4.4 GHz65 W$329
Ryzen 5 3600X6 / 123.8 - 4.4 GHz95 W$249
Ryzen 5 36006 / 123.6 - 4.2 GHz65 W$199

The Ryzen 9 3900X is the only CPU in the list using two core chiplets, each with 6 of 8 cores enabled. AMD has held back on releasing a 16-core monster for now. AMD compared the Ryzen 9 3900X to the $1,189 Intel Core i9-9920X, the Ryzen 7 3800X to the $499 Intel Core i9-9900K, and the Ryzen 7 3700X to the Intel Core i7-9700K, with the AMD chips outperforming the Intel chips in certain single and multi-threaded benchmarks (wait for the reviews before drawing any definitive conclusions). All five of the processors will come with a bundled cooler, as seen in this list.

    It's finally happening!

    I've been wanting to see more and more cores for at least ten years.

    I had expected that clock speed would quit increasing, and mostly it has. The next adolescent bragging rights would be "well my system has 16 cores!", "oh yeah, well my system has 24 cores, so there! And with lights and orange juice cooling!"

    We are at a point where developers in higher level languages are able to effectively use more cores as long as they can structure their problems in certain ways. The more you think about restructuring problems to run on multiple cores, the better at it you get -- I think. I had completely re-thought one problem. (previously described on SN once)

    With modern TVs you don't have to worry about braking the yolk on the back of the picture tube.

      If that was said during the Bulldozer "module" era, then it would have been appropriate. If that was 2015-2016 pre-Zen, then sure.

          I'm eager to see 8-16 cores become mainstream, but there will be cases when the core count is overkill or most cores are idling most of the time.

          What was great about Ryzen (the original) is that it delivered up to 8 real cores (not 4x 2 "core" modules, which led to a lawsuit), along with a huge ~52% IPC gain to bridge the gap with Intel. This even beat their marketing, which had only been promising about a 40% improvement. It looks like Ryzen 3000-series (Zen 2) will boost IPC and clock speeds by just enough to almost match or slightly exceed Intel's latest 14nm++++++ yawner.

          So Intel fanbois (disgusting) were correct to shit on AMD's Bulldozer modules. And in response, AMD did what had become unexpected and became competitive with Intel in multiple dimensions (it's unclear to me whether Bulldozer and successors were ever broadly competitive with Intel on $/performance, when ignoring things like integrated graphics).

          Single-threaded performance is still important. It's a reason why I'm interested in Intel's big.LITTLE-inspired x86 core configuration that was revealed in December.

    While it's great that they're continuing to push hardware advancement I was wondering if any of the new CPU's from Intel or AMD solved the flaws involving Spectre and Meltdown? I realize the companies themselves might not want to bring them up again as they still affect the older chips but I haven't found anything confirming they fixed it on newer ones either.

      Meltdown was a major oversight on Intel's part and should be rectifiable (I don't know if they fixed it or not though). Spectre, though, attacks systems that are fundamental to modern processors (note that all of the major players are susceptible to Spectre) and I don't know if there is any fix that wouldn't severely hurt instruction throughput. Nobody is getting rid of speculative execution and branch prediction.

    Look at a list of processor FLOPS per core and you'll see that the average mark has barely budged over the past decade. Only very new high end CPUs and the odd few elderly server CPUs are significantly above the baseline. 10 cores is 1x better than 4 for the vast majority of software that remains bounded to a single process.
    I mean I'll gladly accept more cores... but I'd yield max_n cores for significantly more OPS per core for a general use desktop.
