AotS: Escalation & Civilization VI

Ashes of the Singularity: Escalation

Image 1 of 6

Running overclocked in Creator mode narrowly yields the best average frame rate during the Ashes of the Singularity: Escalation benchmark

Game mode reduces the core/thread count and available cache, which unsurprisingly results in low performance during this heavily threaded title. The benchmark does appear to favor physical cores over logical processors, as the Local/SMT Off configuration beats the Local/SMT option with all of the architecture's threads accessible.

Civilization VI AI Test

The stock Core i9-7900X is faster than AMD's Threadripper 1950X, regardless of how we configure it. Tuning up to 3.9 GHz at least makes the Threadripper chip competitive.

This benchmark tends to favor physical cores, but we see some jockeying between the stock and overclocked SMT on/off configurations. Notably, Game mode provides impressive performance once we overclock. But it falls to the bottom of our chart in the CPU's stock form.

Civilization VI Graphics Test

The Civilization VI graphics test finds the Local/SMT configuration leading narrowly at stock and overclocked settings. Considering the gulf between Creator mode and the NUMA-enabled configurations (Game mode, Local/SMT On, and Local/SMT), this test appears to favor localized memory access.

Intel's Core i9-7900X suffers due to some of the performance regressions associated with Skylake-X's mesh architecture.

    "extra cores could enable more performance in the future as software evolves to utilize them better"

    I can't believe we're still saying this in 2017. Developers suck at their job.

    "AMD aims Threadripper at content creators, heavy multitaskers, and gamers who stream simultaneously. It also says the processors are ideal for gaming at high resolutions. Ryzen Threadripper 1950X isn't intended for playing around at low resolutions, particularly in older, lightly-threaded titles. ____Still, we tested at 1920x1080____ ...."

    Thank you for being out there for us, Tom's, no other website has ever done that. The only other thing we can hope for is that you'll also do a 2S Epyc 7601 review playing Project Cars in 320x240.

    Each change requires a reboot, chewing up precious time as you save open projects, halt conversations, and try to remember which web browser tabs to relaunch.

    not if you're running the right browser with the right options active. Firefox can remember the last tabs you had open and reopen them upon startup... of course this is within the last Firefox window closed, and you have to properly exit. (no killing the thread(s).)

    When I go to pause the video (ad) your site takes me to another tab. Bye, bye.

    Since this CPU (and Intel's X and XE line) are aimed for big spenders, when are you guys going to test multi GPU in these CPUs?

    Also, you mentioned streaming as part of the big CPU charisma, but there was no actual test with it. Why not just run OBS with the same software encoding settings for each platform and run a game? It's not that hard to do, is it?

    Cheers!

    It's easy enough to disable the JW Player with ublock. Those videos are not considered ads but adblockers, but you can tell it to block anything that uses JW Player, then whitelist any other site that needs to use it for NON-ADs.

    Thanks for this investigation Toms, really thorough and interesting article.

    It's interesting and a little disappointing that an OC to 3.9Ghz seems to pretty consistently achieve a small but measurable bump in gaming. The 1950X can use XFR to get to 4.2Ghz on lightly threaded workloads. Obviously in well-threaded games the CPU isn't going to be able to sustain 4.2Ghz, but it's a bit disappointing it can't manage 3.9-4ghz across the 4-6 cores used in gaming workloads. In fact, judging from the results it seems to be sitting around 3.7-3.8Ghz or so in most games. That seems low to me. There should be plenty of thermal and power headroom available to to get 4-6 cores up to nice high clocks, which should be enough cores for pretty much every game in the suite (except perhaps AOTS). If that was happening we'd see the OC making no difference, or even perhaps causing a slight performance regression in games (like it does in synthetic single-threaded tests). But clearly that's not the case.

    It seems to me that AMD's power management implementation is resulting in some pretty conservative clock speeds in the 4-6 core workload range. That has implications outside of gaming as well, because 4-6 thread workloads are quite common even in the productivity and content creation space. It's hardly a deal breaker (we're only looking a couple of hundred mhz), but I'm curious whether others think AMD is giving up a little more performance than they should be here? Or am I missing something?

    Ryzen hits a certain point in return pretty darn fast for example CPU might only use 1.15V to get 3.6ghz stable but 3.9ghz needs like 1.3V way to much.

    Intel's billions had a lot to say in this.
