Our New 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
  • 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:

Power

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.

Memory

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.

Linux (when feasible)

When in full swing, we wish to return to running LinuxBench 1.0. This was in our 2016 test, but was ditched in 2017 as it added an extra complication layer to our automation. By popular request, we are going to run it again.

Integrated and CPU Gaming

We have recently automated around a dozen games at four different performance levels. A good number of games will have frame time data, however due to automation complications, some will not. The idea is that we get a good overview of a number of different genres and engines for testing. So far we have the following games automated:

For our CPU Gaming tests, we will be running on an NVIDIA GTX 1080. For the CPU benchmarks, we use an RX460 as we now have several units for concurrent testing.

In previous years we tested multiple GPUs on a small number of games – this time around, due to a Twitter poll I did which turned out exactly 50:50, we are doing it the other way around: more games, fewer GPUs.

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.

    It may just be me, but all of the links on the "Pages In This Review" at the bottom of the main page simply return me to the main page. Reply

    But the drop-down to the specific page works as expected. Reply

    It's definitely not just you. I spent a few tries wondering what I was doing wrong and re-read the start of the article until I tried the drop-down menu instead of the links. Reply

    That's my fault, as the hyperlinks need to be manually added. I had messed up the part of the URL after the /show/13945. It should be fixed now. Reply

    R5 2600 all day. These are nice processors for smaller machines, though. Reply

    Heck, even a 2600 can sit comfortably in a HTPC with low-profile cooling. Reply

    Thank you Ian for a good review.

    I completely agree with the conclusion that the 2300X makes perfect sense, but the 2500X is harder to place in the picture ...

    On the other hand, despite 2400G and the 2500X have the same TDP, if I look at the graph with full load power consumption, I can clearly see that the latter has a very generous thermal limit, compared with the 2400G where the thermal envelope seems to be very strictly limited.

    Meaning OEMs will probably be able to use the 2500X for cheaper gaming systems where auto-overclocking is used as a feature and AMD will thus be able to offer something better for a lower price.

    This also allows AMD to push AM4 harder on the market, giving itself the opportunity to future upgrades for AM4 buyers.

    So the 2500X will show considerably better performance than the 2400G despite the similar config (minus the iGPU) while not cannibalizing the 2600 nor the 2400G.

    If AMD manages to sell more 2500X through OEMs, AMD also builds a future upgrade market for itself, unlike Intel that will likely push buyers into purchasing new machines.

    ppl buying these CPUs are not the sort to be upgrading the CPU.. to most the computer is a closed box and is upgraded as a whole . I do wonder where all these cores are going .. I mean its great to have 4 6 8 cores with another 8 hyperthreads .. but who is using all that power ? Lets make 4 cores the absolute limit , unless you have a Govt permit to purchase more. Reply

    Browsers have been getting a lot better at using multiple cores, and websites surely do enough in the background nowadays to justify the effort. Reply
