Ryzen 2 Pre-Test: X370 & X470 Memory Scaling on R7 2700X, 1700X

2018-04-13
so any of these has a rise in two series unboxing embargo lifts going live today we're gonna cut all the and get straight to it so I have a couple of numbers to share with you all so all the more specs you'll hear from everyone else we'll put that at the end some of it is some preliminary preconditions for testing that we need to talk about because rise in 2000 series 2700 X the 2600 X 2600 and the 2700 all which I have here in front of me have some interesting things that we need to take into consideration when benchmarking CPUs they're a little bit different from the original Rison series and so we found a couple of things in the past month of testing where we need to lay a bit of it out on the table and show what are we looking at going into the benchmarking how are we normalizing for variables things like that so today we're gonna be talking about the rise in 2000 series I have a couple of caveats I'll share with you after this ad break this video is brought to you by thermal takes view 37 case the view 37 focuses on highlighting custom PC builds with its full panoramic window and tinted front acrylic and our thermal testing the view 37 performed reasonably well when considering its looks focus build which is partly thanks to the airflow design and the removal of a bottom power supply shroud for a balance of looks and performance check the link in the description below for the view 37 coalminers Andy didn't sample us for this one technically we're not under their embargo for the CPUs we could have posted two reviews quite a while ago we're not doing it for a few reasons one of them is out of respect for other reviewers and the other one is because just working with AMD for the threader for launch we talked with them and said hey this special embargo is for some media Thane is not cool and they gave us their word they wouldn't do it again so provided that remains true we will show some trust and hold the review until embargo lifts so even though we can post it today stick around because April 19th I think at 9:00 a.m. Eastern is when the official review embargo lifts that's when we'll post all the performance numbers as opposed to just a couple of short things today but either way a couple big things I'll just get straight into it the boards the motherboards are a big change x4 seventy boards so far we have a couple of them and they are much stronger in the motherboard BIOS Department than the original rise and launch there are some memory timing issues I'll be showing you in a moment with some charts but overall the boards are better with heatsink design in some cases as you saw at CES they are more stable overall we've only had a few blue screens I'd like that to be 0 blue screens but so far all the blue screens we've had have been entirely related to memory timings and that can be adjusted for as EFI matures which the board vendors will do as they always do post launch so really overall it's a lot more stable than Rison one was at launch we're pretty happy with what we've seen thus far it's looking like it'll shape up to be a good launch in general but again we need to finish up the review and see if there's anything else to discover boards are also shipping with some interesting toggles so xfr 2 and precision boots are things to keep in mind now with testing XFR is extended frequency range it gives Andy an extra couple hundred megahertz and best cases for limited thread applications so if you're using one or two threads you get some extended frequency range as the name implies on top of the the advertised base and boost clocks so XFR is boosted now with acts of r2 they have a couple of new parameters we'll be talking on the review precision boost has changed as well and these are configured in a way that some of the board's shipping stock that we've tested with no modifications all auto will push the CPUs in a way that exits TDP so you start increasing the power consumption by dozens of watts in some cases over TDP but you get more performance it's a bit of a question of what's the correct way to test it and so rather than asking that existential question we tested both and then we'll let you decide in the review but that's something to keep an eye on because it's similar in some ways to how MCE pushes Intel CPUs outside of their specification the difference is XFR is an advertised actual feature of AMD CPUs as opposed to a motherboard vendor prio ver clock so philosophically they're a bit different in terms of if you look at one as fair but not the other then again though if it exits the TDP specification that's another debate entirely and we'll get into that in the review so something to keep in mind when the reviews go live is was XFR to enable those precision reviews to enabled or any other sort of overclocking features enabled whether or not you consider them to be overclocking features so yeah that's that's something to keep an eye on something that we had to take into account because we noticed really high power consumption in some cases but not others and then performance was impacted as well other considerations for testing outside of these we need to talk about relative performance scaling on memory this is something we've talked about a lot with Rison we talked about it with the AP use and it comes down to memory kits and the motherboard timings and their ability to interact with those kids so Rison has been more sensitive to memory kits than Intel CPUs and it's not I should say then Intel platforms because this isn't a matter of necessarily rising as an architecture cares more or in toss an architecture cares less it's more about the motherboard timings and the tuning and bios and whether or not it's been optimized for the specific kit of memory you're using because Rison is still a relatively immature platform and I don't mean that in a derogatory way I mean it's literally a year old in terms of market consumption whereas Intel has been on the same platform for eons at this point so that's something that all that that will become better with age and it's not that bad these days anyway but there is an important thing to look at and that's memory scaling so we can talk about that for a bit this is important for test planning because memory kit heavily impacts performance in some scenarios and it's a bit of a balancing act we can throw the best kit we have at the cpu but it doesn't mean it'll perform well it comes down to the motherboard and how the timings are on the motherboard and how their BIOS is for those tertiary and lower-level timings some of our best kits strictly for my timings in frequency perspective actually don't perform that well whereas some of the moderate kits perform great just because the motherboard happens support that kit better out of box and the pre-release version of BIOS what I'm going to do now is show a chart I will wait till I'm done talking here but we'll put a chart on the screen technically if you're under the am the embargo I think you probably can't do this but we're not showing full performance we're not going into a review we're not using absolute numbers we're using relative numbers I'm allowed to do it because I didn't get the CPU from AMD but like I said we're holding the rest of it out of respect for other reviewers and hopefully and these sticks to their word do not do special thread Ripper style and Barbie was this time for four reviewers that they favor so under those conditions we're just gonna show some relative performance scaling because I can to demonstrate the memory kit impact and why we chose one kit versus another and also a bit of discussion on X 370 versus X 470 scaling with rise in 1000 series CPUs I'm not going to go into detail on which motherboards were using today we have most of the board's but I'll talk about the board's more post-launch so again these are relative numbers percent offsets from a baseline 100% which will be established with our Corsair Vengeance lpx thirty-two hundred megahertz kit last year some time we began using a guille thirty-two hundred megahertz CL 16 memory kit and this was provided by Andy with the r5 CPUs so we stuck with it because we I mean they sent it and it performed pretty well at the time now we've kind of learned just from working with rising to and the new BIOS and motherboards that that's not the best kit to use so we did some testing here and looking at some brief numbers starting with an X 470 board of an unspecified make and model we ended up at about 93 percent of the corsair kits performance when using guile meaning that guile performed at about 93 percent of the Corsairs baseline 100 percent performance this is for gaming only and is more latency intensive than applications like blender where memory kit matters a lot less than capacity our range of scaling as you see here is anywhere from seventy nine percent to ninety nine point seven percent of total performance of the corsair baseline kit depending on which game is being used so there's a bit of room here so d nine percent is it's quite a bit lower and show us some of the weaknesses in this kit with the motherboards that we were testing on but comparing the a 1700 X on X 370 versus X 470 same CPU different platforms we noticed that the earliest EFI revision which has since been replaced you'll did poor memory timing on the X 470 platform with the 1700 X it was bad enough that even 1440p testing which should almost always become a GPU benchmark by proxy but it said 85% of baseline performance the X 370 board under the same conditions would post 91% to 99% of baseline performance and the difference comes primarily from timing and tuning settings and other issues in general just with the early BIOS revisions of X 470 as we're just applying X and P for this simple test but improves a point and for that first chart it was a 2700 X stock but again you don't have any absolute numbers to work off yet so things to consider memory kit matters a lot EF 5 revision matters a lot there have already been a couple of them and the earliest versions of BIOS that we used before kind of the the more rise into proper biases were pushed those had issues with things like XF are to behavior and memory timings in general just potentially causing blue screens or being loose enough that performance is impacted that's being corrected which means that we've been basically iterating on our testing and retesting stuff as new revisions have come out to make sure that we have the latest data that reflects something close to what the consumer gets so there may be a 0 our BIOS change there normally is with all these platforms Intel or AMD what we're doing our best to account for those so we'll keep the rest the details under wraps until I review again out of respect of other reviewers and Andy's show of trust to move away from special embargoes but for now this is information provided to illustrate what we've spent the last couple weeks doing researching fair testing conditions basically so check back for more scathing information our review now as for other stuff oh one more thing I guess ashes of the singularity was one of the games in those charts that proves very sensitive to performance scaling a hyper sensitive sometimes that's also a matter of looking into why a specific game performs a specific way and ash as we talked about with an Threat thread Ripper launched about the way it interacts with Numa versus uma for example for the memory access stuff like that so let's get on to the Restless stuff now and I said you have the earlier this is basically that part but it's still important information there are five 2609 x $200 for that part 6 cores 12 threads and frequency listed on the screen $230 there are 5 2600 X 6 cores 12 threads a bit faster in the frequency Department the r7 2700 where it gets interesting so the 1700 is the CPU that we gate we gave it an Editors Choice Award we called it rise ins champion basically said this is the r7 to get forget the 1800 X it's waste of money 1700 ex-con in between them and there are valid reasons to buy those but when I say it's a waste of money I mean from our perspective as people who would just buy the $200 cheaper at the time of launch 1700 and then overclock it in 5 minutes and have something very close to an 800 X anyway that point aside the 2700 is 300 bucks so that's 30 lower than the 1700 which we heavily endorsed and really likes at $330 so performance remains good and the platform remains good then $300 for 2700 is extremely competitive and that's something we want to see the 2700 X which is presumably the replacement to the 1700 X is $330 and and that one like the 2700 they're both 8 cores 16 thread the frequency is 3.7 the three to four point three gigahertz with exif r2 on the 2700 X and as 3.2 to 4.1 on the 2700 9x you can obviously overclock they're all unlocks just like before so I think that's most the basics here we have some extra things I'd like to show but like I said we're gonna hold it what you really need to know is there's core counts they're basically same core and thread counts as the preceding 1 X 0 0 numbers so 1 6 0 0 1 6 0 0 X same idea to the 2000 series same for the 2700 C's so what we're left with then is waiting april 19th is when you should check back we're posting our review when all the others go live at 9:00 a.m. Eastern on April 19th and we'll have a ton of extra testing this by the way as an aside here as kind of a statement on the industry this of going through a side channel for a part has taught me and us as a team a lot because it's allowed us to get way more hands-on with something way before launch and the parts are still more or less retail ready so hardware side they haven't changed EFI stuff like that yes it updates we have to iterate our testing it's extra work in that department but the important thing is that having this extra time when these companies typically give you about a week to test stuff has proven extremely useful and valuable because it's allowed us to troubleshoot issues things like blue screens stuff like that before we're a zero hour on review day you're still not sure why something's crashing or perform badly or crap or any kind of bad behavior with performance and what you're left with is having to make a judgement call of do I mentioned this in the review and if I do how much emphasis do I put on it being the platform's fault versus how much emphasis do I put on it being maybe the CPU the motherboard or tester error because maybe we don't understand something out of zero hour and it's hard to get in contact with the right people who actually know things so this has given us time now that we've had several weeks to do testing for once to look into all that and eliminate any question at all of what's going on so I feel much more confident in the review then most other reviews which is a great feeling it's unfortunate that you have to go through backchannels to do it basically and of course they don't want to give you the parts too early partially because they're trying to prevent things like leaks and all these companies partially because they're trying to control the media cycle things like that limit how much digging you can really do on a product but what we've seen so far with rising to is looking good so expect a reasonable review it actually looks like how much stronger launch than last year so I'm pretty happy about it it's it's just kind of enlightening to me that going through this back channel for once for this specific type of product has given us a much more comprehensive review and not in a way that's negative towards the product just in a way that's overall positive because it teaches everybody about what's going on how something works you can really dig in the hack so far to work stuff like that stuff we'd never have time for normally so yeah I don't really know what my plan is going forward because obviously you work on building a relationship with the companies like I am the Erie building that relationship after arguing over the thread repair embargoes but at the same time I really like understanding how stuff works ahead of launch so it's kind of weird we have to make that balancing act now either way though check back April 19 subscribe for more as always gonna patreon.com slash gamers and stop site directly I'll have an article in the description below with the specs table maybe some other basics if you want to click that and read more go for it and as mentioned store that game is Nexus 9 at to pick up a mod mat like this one I'll see you all next time
