Our Testing Suite for 2018 and 2019

Spectre and Meltdown Hardened

In order to keep up to date with our testing, we have to update our software every so often to stay relevant. In our updates we typically implement the latest operating system, the latest patches, the latest software revisions, the newest graphics drivers, as well as add new tests or remove old ones. As regular readers will know, our CPU testing revolves an automated test suite, and depending on how the newest software works, the suite either needs to change, be updated, have tests removed, or be rewritten completely. Last time we did a full re-write, it took the best part of a month, including regression testing (testing older processors).

One of the key elements of our testing update for 2018 (and 2019) is the fact that our scripts and systems are designed to be hardened for Spectre and Meltdown. This means making sure that all of our BIOSes are updated with the latest microcode, and all the steps are in place with our operating system with updates. In this case we are using Windows 10 x64 Enterprise 1709 with April security updates which enforces Smeltdown (our combined name) mitigations. Uses might ask why we are not running Windows 10 x64 RS4, the latest major update – this is due to some new features which are giving uneven results. Rather than spend a few weeks learning to disable them, we’re going ahead with RS3 which has been widely used.

Our previous benchmark suite was split into several segments depending on how the test is usually perceived. Our new test suite follows similar lines, and we run the tests based on:

  • Power
  • Memory
  • SPEC2006 Speed
  • Office
  • System
  • Render
  • Encoding
  • Web
  • Legacy
  • Integrated Gaming
  • CPU Gaming

Depending on the focus of the review, the order of these benchmarks might change, or some left out of the main review. All of our data will reside in our benchmark database, Bench, for which there is a new ‘CPU 2019’ section for all of our new tests.

Within each section, we will have the following tests:


Our power tests consist of running a substantial workload for every thread in the system, and then probing the power registers on the chip to find out details such as core power, package power, DRAM power, IO power, and per-core power. This all depends on how much information is given by the manufacturer of the chip: sometimes a lot, sometimes not at all.

We are currently running POV-Ray as our main test for Power, as it seems to hit deep into the system and is very consistent. In order to limit the number of cores for power, we use an affinity mask driven from the command line.


These tests involve disabling all turbo modes in the system, forcing it to run at base frequency, and them implementing both a memory latency checker (Intel’s Memory Latency Checker works equally well for both platforms) and AIDA64 to probe cache bandwidth.

Scale Up vs Scale Out: Benefits of Automation

One comment we get every now and again is that automation isn’t the best way of testing – there’s a higher barrier to entry, and it limits the tests that can be done. From our perspective, despite taking a little while to program properly (and get it right), automation means we can do several things:

  1. Guarantee consistent breaks between tests for cooldown to occur, rather than variable cooldown times based on ‘if I’m looking at the screen’
  2. It allows us to simultaneously test several systems at once. I currently run five systems in my office (limited by the number of 4K monitors, and space) which means we can process more hardware at the same time
  3. We can leave tests to run overnight, very useful for a deadline
  4. With a good enough script, tests can be added very easily

Our benchmark suite collates all the results and spits out data as the tests are running to a central storage platform, which I can probe mid-run to update data as it comes through. This also acts as a mental check in case any of the data might be abnormal.

We do have one major limitation, and that rests on the side of our gaming tests. We are running multiple tests through one Steam account, some of which (like GTA) are online only. As Steam only lets one system play on an account at once, our gaming script probes Steam’s own APIs to determine if we are ‘online’ or not, and to run offline tests until the account is free to be logged in on that system. Depending on the number of games we test that absolutely require online mode, it can be a bit of a bottleneck.

Benchmark Suite Updates

As always, we do take requests. It helps us understand the workloads that everyone is running and plan accordingly.

A side note on software packages: we have had requests for tests on software such as ANSYS, or other professional grade software. The downside of testing this software is licensing and scale. Most of these companies do not particularly care about us running tests, and state it’s not part of their goals. Others, like Agisoft, are more than willing to help. If you are involved in these software packages, the best way to see us benchmark them is to reach out. We have special versions of software for some of our tests, and if we can get something that works, and relevant to the audience, then we shouldn’t have too much difficulty adding it to the suite.

    Intel ice Lake for performance laptops should be out by 2019 christmas. Then we will see if there are any IPC improvements in this new architecture. Probably not much... Reply

    I think that Intel need 10nm for Data-centers for higher core count and profit, and their production focus will be on this area and not consumer desktop PC's.
    I don't see 9700K/9900K 10nm competitor until 2020.

    Sunny Cove and Willow Cove are intermediate designs until the release of Ocean Cove, the "brand new" CPU architecture Jim Keller was hired to lead the design of. Since Ocean Cove has not yet appeared in Intel's schedule it either means that it will not be ready before at least 2022 or Intel is just being secretive.

    Or it might just be Golden Cove. Since Golden Cove will apparently be Intel's next new design, if the it is not actually Ocean Cove, then Ocean Cove will not be released until 2023 at the earliest (at 7nm). That's because Intel has never released two new designs one after the other without an optimization in-between. It's also possible that Intel will just "pull a Skylake" and rather than use a new design for Golden Cove they will just.. re-optimize it. In that case Ocean Cove should be released in 2022, right after Golden Cove.

    For intel's sake (and ours), I hope they're working furiously on quantum CPU's. Reply
  • peevee - Monday, February 4, 2019 - link

    So far, quantum is looking like a dead end. Maybe for specialized coprocessors in cryo environments in 10 years, but not for general-purpose computing AT ALL.

    There are much better, actually realistic directions for general-purpose computing on non-Von Neumann architectures, and that is where the future lies now that Moore's law is firmly dead and buried.

    There is not release information about desktops on Ice Lake. But I would not doubt that Ice Lake on desktop at that time. It going to be fun to compare new laptops and even desktops at that time.

    But keep in minor to Intel desktop market is a minor market and once performance is up, I would not doubt we will not see any difference in desktop vs mobile chips
  • Santoval - Monday, January 28, 2019 - link

    We don't know how well Ice Lake / Sunny Cove will perform, but no matter how good it performs AMD will still have a market lead of 6 to 7 months (assuming a release of Zen 2 based Ryzen CPUs in May or June and an Intel HVM release of Sunny Cove in December).
    This assumes that Intel does not screw up again and moves back the launch of Sunny Cove into 2H 2020, which would be frankly catastrophic, at least for their client wing. Their 14nm process has been milked dry, they can no longer extract any more performance from it.

    "This is an M.2 module, which means it could be upgraded at a later date fairly easily."

    No, you can't. Lenovo only lets wifi/bluetooth cards with their custom firmware in their systems. If you boot the system with a standard (say Intel) wifi card, it refuses to boot.

    That's the reason I stopped buying lenovo laptops despite liking their build and design.

    They've stopped doing that since about ~2 years ago. Reply
