Intel Releases Final Core i9 Specs and Release Dates -- And Threadripper Is Faster (Sometimes) (pcworld.com)

Posted by msmash on from the footprints dept.

On Monday, Intel took the wraps of final details of its Core i9 microprocessors. From a report: Remember that Intel's Core X-series family (also called the Core i9) was announced with several key omissions: namely the clock speeds of the 12-core Core i9-7920X and above, as well as the thermal design power, or TDP. On Monday, Intel filled those in. The 12-core Core i9-7920X launches Aug. 28 while the 14-, 16-, and 18-core Core i9 chips ship on Sept. 25. Perhaps most important, though, is that we now know how fast Intel's Core i9s will run. When Intel inadvertently revealed that its 12-core Core i9-7920X was 2.9-GHz -- slower than the comparable AMD Threadripper -- a subset of the internet had a small freakout. We now know that that will be true for the remaining Core i9s as well, but with a big caveat. Here are the remaining speeds and feeds for the high-end Core i9 chips:
Core i9-7980XE (18 cores, 36 threads): 2.6GHz; Boost, 4.2GHz to 4.4 GHz.
Core i9-7960X (16 cores, 32 threads): 2.8GHz; Boost, 4.2GHz to 4.4 GHz.
Core i9-7940X 14 cores, 28 threads: 3.1GHz; Boost: 4.3GHz to 4.4GHz.
Core i9-7920X (12 cores, 24 threads): 2.9-GHz; Boost: 4.3-GHz to 4.4GHz.

Note that the boost speeds refer to both Intel's Turbo Boost Technology 2.0 and 3.0. [...] Essentially, both Intel and AMD can claim the title of fastest processor. Threadripper's base clock speeds are faster, but Intel's boost speeds climb higher than Threadripper can. It's also important to note that while Threadripper consumes 180 watts, even the fastest Core i9 chips Intel has announced have a lower TDP of 165 watts.

      There's not too many workloads that require 32 threads at full capacity all the time. Many single task workloads have serious diminishing returns above 10 threads. They'll be great for rendering. Video encoding is often used as an example use case, but I really have to wonder why this is being down on a CPU and not a DSP or GPU.

      Even in a heavy VM environment, it's unlikely that maximizing thread count is worth optimising over higher per thread IPC, as most VM workloads are I/O limited as core count increases, and higher IPC tends to optimise for better overall power usage. I'd wait and see what the full benchmarks look like. There's still NDAs in effect for benchmarking atm (Aug 10th), so the only benchmarks we're seeing obviously show TR strengths.

      TR has 64 PCIe lanes yes, but 4 lanes are reserved for the CPU to chipset, so there's really only 60 CPU PCIe lanes (Disappointingly misleading marketing by AMD here, you guys used to be the more trustworthy option), where the chipset (X390) provides an extra 5 lanes (one x1 and one x4) for a total of 65 lanes.

      The i9 provides 44 lanes with none used for chipset communication (Uses DMI3), and 24 lanes via the X299 chipset, for a total of 68 lanes. And yes those 24 chipset lanes use the equivalent of 4 lanes to the CPU, but not all use is simultaneous, and devices can communicate directly with each other, so real world performance difference may depend on the application.

    4. Re:Core i9 is just too dam hot by MrFlibbs · · Score: 3, Informative

      Data centers don't care about noise or heating like an oven, they have massive power supplies and massive cooling. At worst you'll replace one 4P server with one 2P server with 2x the cores. Or two 2P VM platforms with one 2P VM platform with the same number of cores. I very much doubt they'll ever feel it's too much processing power in one place.

      This is just plain wrong -- data centers care very deeply about power consumption. Since data centers pack thousands of CPUs into warehouse-size rooms, even a single extra watt per CPU is a big deal. Higher power consumption means a greater power delivery requirement for the room, more cooling, a bigger UPS requirement, and a bigger power bill. Operating costs are driven by transactions per second per watt.

      High performance computing and high-end desktops are pretty much the only remaining markets where power consumption is a secondary concern. This has not been true for data centers in a long time.

    (Those are settings in WINDOWS you can adjust to take advantage of added cores as you upgrade to CPUs w/ more cores, for example).

As I've previously written, my Ryzen Linux boxes have been working out great except in cases of intentional torture testing with these heavy parallel compilation tasks. Even when carrying out other heavy, non-compilation (GCC or Clang) parallel workloads in recent days, from server tasks to scientific processing, my Ryzen test boxes have been stable. I'm still using Ryzen 5 on my main desktop system without any faults in day-to-day use on Fedora 26 Linux."

    "Ryzen customers believe to be affected by the problem can contact AMD Customer Care. Some of those who have contacted customer care about the segmentation faults have in turn been affected by thermal, power, or other problems, but AMD says they are committed to working with those encountering this performance marginality issue under Linux. AMD will also be stepping up their Linux testing/QA for future consumer products."
