Intel Launches 16 and 18-Core Core i9 Desktop Chips To Take On AMD Threadripper (hothardware.com)

Posted by BeauHD on from the more-the-merrier dept.

MojoKid writes: Intel has officially launched its Skylake-X processor offering in response to AMD's Ryzen Threadripper series of desktop CPUs. The new Core i9-7980XE and Core i9-7960X are 18 and 16-core configurations respectively, with 2.6GHz and 2.8GHz base clocks and 4.4GHz max boost clocks. Both chips support Intel HyperThreading, with 36 threads of processing for the 7980XE and 32 for the 7960X, while both also have 44 lanes of PCI Express connectivity and support for DDR4-2666MHz memory. Both chips also utilize Intel's X299 chipset platform and are LGA 2066 socket compatible. The Core i9-7980XE has 24.75MB of shared L3 cache, 1MB of L2 cache per core, and a TDP of 165W. The Core i9-7960X's details are essentially same, though two processor cores and the cache associated with them have been lopped off. The Core i9-7960X has a couple of advantages, however, in that its base clock is 200MHz higher than the flagship Core i9-7980XE and it has higher all-core frequency boost to 3.6GHz, while the 7908XE tops out at 3.4GHz on all cores. The new chips are multi-threaded beasts in the benchmarks, posting the highest scores seen to date in heavily threaded workloads. They also offer strong single-threaded performance that outpaces AMD's Ryzen processors. Power consumption is surprisingly good as well and only marginally higher than the 10-core Core i9-7900X. However, at $1999 for the Core i9-7980XE and $1699 for the Core i9-7960X, as usual with Intel high-end chips, they're certainly not cheap.

    So, it's a Xeon that can't do ECC. Seems totally worth it.

      The advantage of ECC RAM is NOT about "oh, the system has been up for 2 years without a glitch, see, ECC RAM was a waste of time".

      The whole point is that you you can see that there were no errors.

      Just finished a 2 month compute task? No memory errors? Great, the code worked and any abnormal results are due to coding mistakes. Otherwise, you might be tempted to run the whole thing again on the off-chance it might have been a memory error.

      I've had rigs up for > 5 years without a single ECC error, but I do not for one second believe ECC to be a waste of money.

  2. Re:165W by Mad+Merlin · · Score: 5, Insightful

    The Pentium 4 was also only a single core (or dual core if you count the short lived Pentium D line, which was based on Pentium 4 cores glued together) with vastly worse IPC. These have up to 18 cores and will chew through multithreaded workloads something like 50x faster than the fastest Pentium 4, while using comfortably less than double the power at full tilt (the i9-7980XE uses more than it's TDP at full load, around 195W, but recall that the Pentium 4 had a 115W TDP). Also, the idle and lightly loaded power usage on the i9-7980XE is dramatically lower than any Pentium 4. Unless you're running the CPU in part of a render farm that works 24/7 or something, it's going to be drastically quieter and use less power overall than any Pentium 4, not to mention absolutely obliterate it on performance.

    Having said that, I'd still opt for a Threadripper over one of these if I was building a computer today. The extra raw performance from the i9-7980XE over the 1950X (between low single digit %s to around 40%, depending on the test) is nice, but when you consider the weaker X299 platform (fewer PCIe lanes, no ECC) and the toothpaste under the IHS in the Intel (meaning it's impossible to properly cool it without delidding and potentially destroying the CPU, not to mention the runaway power usage even with a mild overclock) for double the cost, Threadripper seems like the obvious pick.

  3. 44 lanes! by darkain · · Score: 3, Insightful

    44 lanes of PCIe? That is only four more lanes than my first generation Xeon E5 workstation that I'm using right now, which is only a quad-core chip. Granted though, this machine is pretty maxed out with that tho, even with just one GPU, thanks to PCIe SSD, dedicated sound card, and 10gbe networking.

    Depends on what you are doing. Is single-threaded? Multi-threaded? Needs ECC, Memory bound? Computer bound? etc.

    For gaming? Nope. An i7-7700K is still faster then the iCore 9. LOL.

    For rendering? Yep 2:07 vs 7:19

    However, it is important to point out:

    * Intel CPU's are the fastest CPU's around but you literally PAY through the nose 2x- 5x for a measly ~10% increase in performance.
    * AMD's Ryzen and Threadripper CPUs have WAY better bang/buck. i.e. In Blender 2.78c AMD's Theadripper 1950X ($999) is faster then the Xeon E5 2699 v4 ($4,115). LOL.

    Conclusion:

    Is the i9-7960X worth a whopping $700 more then Threadripper 1950X?

    For many people, the answer is no. That is money that could be spent into a better GPU or more RAM/SSD.

    What CPU is "best" depends on your workload.

  5. AMD - Job well done by Lady+Galadriel · · Score: 5, Insightful

    Competition is a good thing. Without AMD, and all the people who helped keep them alive, Intel would have sat on things like this.

    In the long run, Intel parts are likely going to be better. They have more money, more chip desigers, and un-fortunantly more customers, (some that will pay outragous prices).
