日本电子维修技术 主板AlphaC有话想说 点评当前Z390主板

绘制Z370、Z390主板天梯图的大神AlphaC最近在OCN顺便点评了当前各主流Z390主板

Godlike is using top tier VRM but it simply isn't worth the cost (16x 60A TDA21462 Powerstages via doublers) unless you plan on using it as a WIFI accesspoint. It's the same as Aorus Xtreme but with a worse heatsink , no backplate , no 10GBps LAN (easily $70-100), and lack of Thunderbolt (worth $60-100 easily). Similarly I'd find it hard to rationalize the Aorus Xtreme Waterforce since the Xtreme already runs incredibly cool as shown by hicookie (Gigabyte's inhouse overclocker) : it's more of a Veblen good at $900.  The Aorus Xtreme's backplate also uses heatpipes, so it isn't only dissipating heat to the air but also via phase change of the working fluid.

The ROG Maximus XI Extreme is using 10x IR3555 60A powerstages and per elmor there's no doublers. Functionally I would buy the Apex over the Extreme. If you look at the memory overclocking done, it's higher on Apex and Gene. The backplate on the Extreme is only aesthetic, it doesn't cover the back of the VRM section and has no thermal properties.

The ROG Maximus XI Formula is essentially verbatim from the Hero (8x Sic639 50A powerstages) , you're paying for the VRM block + backplate and fluff features.
      
Other than putting Gigabyte Z390 M non gaming (likely 4 phase board with 4 sets of mosfets or doubled low side) in the red section , there's nothing of note that is worth changing. If there's more information on the MSI Tomahawk & Phantom Gaming 6 I'll move them around a bit if necessary. Until there's more definitive information I will leave it as is.

The recent video by der8auer and the testing done by Hwinfo NL suggests Godlike / Extreme / Gene are better for situations where the power draw exceeds that of air/AIO level water (> 250W) but worse than the well heatsinked Aorus Master in real situations. I saw a recent zero airflow test on xfastest where the Aorus Pro hit 90°C with a Asetek style closed loop water cooler only at 260W , it was below 80°C at ~210W. It just happens that the CPU will likely roast (on ambient) before the Aorus Master becomes a concern , as 90% efficiency is maintained up until 25A per powerstage which is ~300A for that board as it uses 12 of them. Keep in mind that the Intel spec is 193A for 8 cores and 138A for 6 cores. The testing by a user on OCN with a reworked z370 Gaming 7 using 8x ISL9927B powerstages ($7 each versus <$2 each)  as opposed to the 12x SiC634 used on the Aorus Pro performed similarly.

For the ROG Extreme/Gene the IR3555 is likely 90% efficient up to 40-45A per powerstage (~400-450A for the whole power delivery) based off IR3550 numbers, but the contention comes from the weaker heatsinking and the lack of doubling scheme. Even if peak power it is capable of is higher, the heat density is higher due to fewer powerstages in addition to the worse heatsinking. In addition, you would need to exceed Intel spec for that to be relevant (likely over 300W to the CPU) and require immense cooling either subzero or a ridiculous custom water loop just for the CPU. Most users hitting 200W or so already reach ~95°C on the CPU and multiple instances I have seen people exceed 105°C (the default TJMax) on the CPU with 250W.

The thing to remember is that any weak cooler will heat the board higher due to the CPU heat also going into the PCB. You're combating both the excess heat from the CPU as well as that from the power delivery to it.  As you scale your CPU cooling you also relieve heat from the power delivery. The conduction of the copper in the PCB is massively higher than the fluid in a loop , the liquid cooler's radiator to the air, or from an air cooler to the air. That is what makes the Aorus Master's backplate effective.

I'm pretty impressed by the increase in overall featureset & power delivery on the Aorus Xtreme (~$550), Aorus Master ($250-300 typically), and Pro (~$180-200) at their respective pricepoints. There's minor differences noted such as PCB layers or whatnot, but for the average user with 1 GPU and one or two M.2 the Pro is already capable of doing what they need to do , short of > 4 GHz memory which is extremely niche and CPU quality dependent. The Aorus Master has been seen clocking memory to 4500MHz, so that's definitely possible and for people that actually intend to extensively finetune overclock their memory the "single BIOS" switch is more of a necessity.
* There's a $10-15 premium from the Aorus Elite to the Aorus Pro. The Aorus Elite lacks a heatpipe at the VRM heatsink, is using Apaq Taiwanese capacitors rather than Japanese FP caps, has lower number of fan headers, and also lacks USB 3.1 gen 2 type C at the rear panel. I don't feel that going $10-15 cheaper is worth it for this reason.

ASUS has sort of a PR crisis with the ROG series this time around but for most people the difference is minor to what was implemented on Z370 especially with the older slower Vishay ZF906 powerblock variant. PCBs were reworked and measurement of voltage was reworked but ultimately overall the boards haven't been as thoroughly overhauled.

The Taichi was reworked a slight bit from Sinopower/Fairchild variants to only TI NexFET powerblocks with doublers. This means a higher peak efficiency as the switch times are quicker ; the RDS(on) is relatively similar.

Not really sure of the reasoning that MSI had to keep using Onsemi  powerpaks on their $300 MSI MEG Ace. It was a poor decision and has led  to a price drop early on to ~$260. They sort of get away with it due to  the ASUS PR fiasco and the larger VRM heatsink. There's room to cut the  price further due to the cost of making it and as the Taichi and Aorus  Ultra are both performing roughly on par and have 3 M.2 and debug code  LEDs.

That's not to say the midrange Asus Z390-E STRIX , Asrock Phantom Gaming 6, or the MSI Edge AC (ATX version) are terrible. The Z390-E is a rework from Z370 , eschewing the 8 sets of low RDS(on) mosfets for 8x 45A Onsemi powerstages (some have the Vishay 50A ones too), despite retaining 5K hour Taiwanese Apaq capacitors. I just don't find the value proposition as strong for these three midrange boards because they don't exist in a vacuum. The MSI Pro Carbon is an anomaly in that it is worse thermally than the MSI Edge as shown on multiple sites, with the only notable upgrade being the WIFI speed. Asrock dropped the IR35201 from Z370 K6 in favor of UPI semi's UPI9521 , albeit retaining the same 2 variants of powerblocks. As it (the UPI PWM) is used on the midrange MSI edge and pro carbon there's no reason to believe it's superior to the IR35201 which are used on the higher end boards.

The Asrock Extreme4 has the issue of not having any debug features whatsoever other than the dual BIOS. If it retained the Debug Code LED from the Phantom Gaming 6 it'd be a far better board. Another odd design choice it and the Phantom Gaming 6 have is the lack of extra USB on the rear panel (6 total only , although all are USB 3.0 and 3.1) and the inclusion of D-sub display output on a Z390 board.

While non Aorus boards from Gigabyte such as the Gaming SLI , Gaming X, and M Gaming are adequate, you'd be well advised to pay attention to the featuresets.

Lower than that in the product stacks you're looking at boards that are iffy if you intend to run any AVX workloads (such as Handbrake x264 or Blender) while overclocked. The Z390 Edge mATX and Tomahawk from MSI aren't proven yet , I've only seen one or two reviews. The STRIX Z390-H is an outright cash grab based on its specs vs its naming, the Z390 Phantom SLI/ac has been shown to throttle even in AIDA64. TUF boards carry an ASUS premium but otherwise aren't noteworthy.

For ITX however, the Asrock Z390 Phantom ITX is definitely the board to get : it's the only one with Thunderbolt and the only one with a power delivery that truly won't limit you on ambient. Stepping down from mATX to ITX means the audio is typically slimmed down in footprint , which is meaningless to the people that claim USB DAC is the only way to truly isolate audio. The 2nd M.2 slot is retained on all Z390 ITX (ASUS STRIX, Gigabyte Aorus ITX, MSI edge). USB count at the rear panel between mATX and ITX is relatively the same (except the ROG Gene) and worst case with the Phantom ITX you can use the Thunderbolt with a hub for more USB ports.


机翻
Godlike正在使用顶级VRM，但它不值得花费（16x 60A TDA21462 Powererstages via doublers），除非你打算将它用作WIFI接入点。它与Aorus Xtreme相同，但散热器更差，没有背板，没有10GBps LAN（容易70-100美元），而且没有Thunderbolt（价值60-100美元）。同样地，我发现难以合理化Aorus Xtreme Waterforce，因为Xtreme已经运行得非常酷，如hicookie（技嘉的内部超频玩家）所示：它更像是一个900美元的Veblen。 Aorus Xtreme的背板也使用热管，因此它不仅可以散热到空气中，还可以通过工作液的相变来实现。

ROG Maximus XI Extreme使用10x IR3555 60A电源，每个elmor没有倍增器。从功能上来说，我会在Extreme上购买Apex。如果你看看内存超频完成，它在Apex和Gene上更高。 Extreme上的背板仅美观，不覆盖VRM部分的背面，没有热性能。

ROG Maximus XI Formula基本上是Hero（8x Sic639 50A powertages）的逐字记录，你需要支付VRM模块+背板和绒毛功能。

除了在红色部分放置Gigabyte Z390 M非游戏（可能是4相板，4组mosfet或加倍低侧），没有任何值得注意的变化。如果有更多关于MSI Tomahawk和Phantom Gaming 6的信息，我会在必要时将它们移动一下。除非有更明确的信息，否则我将保留原样。

der8auer最近的视频和Hwinfo NL的测试结果显示Godlike / Extreme / Gene在功率消耗超过空气/ AIO水位（> 250W）的情况下更好，但在实际情况下比散热良好的Aorus Master更差。我在xfastest上看到了最近的零气流测试，其中Aorus Pro在温度为260W时使用Asetek型闭环水冷却器达到90°C，在210W时低于80°C。恰好在Aorus Master成为关注点之前，CPU可能会在环境中进行烘烤，因为90％的效率一直保持到每个功率计25A，因为它使用了12个，因此该板的功率为300A。请记住，英特尔规格为8核193A，6核138A。用户在OCN上使用8x ISL9927B电源重新设计z370 Gaming 7进行测试（每个7美元，每个<2美元），而Aorus Pro上使用的12x SiC634则相似。

根据IR3550的数据，对于ROG Extreme / Gene而言，IR3555的效率可能高达80-50A，每个功率级为40-45A（整个功率输出约为400-450A），但争议来自较弱的散热和缺少双倍的方案。即使能够达到的峰值功率更高，由于除了较差的散热之外的较少的功率值，热密度也较高。此外，您需要超出英特尔规范才能获得相关性（CPU可能超过300W），并且需要对零度进行大量冷却，或者仅针对CPU进行荒谬的自定义水循环。大多数达到200W左右的用户已经达到了~95°C的CPU和多个实例我看到人们在250W的CPU上超过105°C（默认的TJMax）。

需要记住的是，由于CPU热量也进入PCB，任何弱冷却器都会使电路板升温。你正在对抗来自CPU的多余热量以及从供电到它的热量。在扩展CPU散热时，您还可以减少电力供应的热量。 PCB中铜的传导大大高于回路中的流体，液体冷却器的散热器到空气，或从空气冷却器到空气。这就是Aorus Master的背板有效的原因。

Aorus Xtreme（约550美元），Aorus Master（通常250-300美元）和Pro（约180-200美元）各自的价格点上的整体功能集和功率输出的增加令我印象深刻。有一些细微差别，例如PCB层或诸如此类的东西，但对于拥有1个GPU和一个或两个M.2的普通用户，Pro已经能够做他们需要做的事情，缺少> 4 GHz内存，这是非常小众的CPU质量依赖。 Aorus Master已经看到内存达到4500MHz，所以这绝对是可能的，对于那些真正打算对其内存进行大量微调的人来说，“单BIOS”开关更为必要。
*从Aorus Elite到Aorus Pro有10-15美元的溢价。 Aorus Elite在VRM散热器上没有热管，使用的是Apaq台湾电容而不是日本FP电容，风扇接头数量较少，后面板上也没有USB 3.1 gen 2 C型。因为这个原因，我不认为价格低10-15美元是值得的。

这一次，华硕与ROG系列产生了一场公关危机，但对于大多数人而言，这与Z370上的实施情况相差甚远，尤其是老款。

总结看来就是master强无敌？无主动散热情况下温度表现比旗舰还强

作者很挺大雕

作者也喜欢让mos跑在效率高的状态下来推断主板的负载能力，50A的那个啥sic634  mos，负载25A时候效率90%，负载再大供电效率降低了，主板散热什么的就会恶化了。所以实际负载只当25A*12项算，囧


看上去只比极限玩家4高100块钱的PG6也获得作者的好评，这100块钱买到了额外的频率发生器，数字检测灯，开关和重启键，黑化的底座，额外的网卡（把极限玩家4PCB 上缺的都补齐了），本来我很看好，但是实际拆解用的mos还是7341 EH，而非作者写的仙童的那个啥，这个玩意在我的z370极限玩家4上表现不太好啊，功耗和发热。

看了前几段，后面文长不看。总结：

Godlike牛逼，但是贵的不值。M11F用着和M11H一样的供电，不值。M11E好东西，但是我更推荐M11A(没发布)。M11G供电和M11E一样，挺不错。超频大牛用Godlike、M11E、M11G这仨。

有些媒体很矛盾,喜欢评测最好的主板,但CPU都是小超,如果只是5.0 5.1这种频率根本没有必要用到旗舰主板.

评论

媒体评测主板是为了恰饭，没有任何一家媒体能给你评测超频能力

评论

八九百的不是Intel原装卡吧，I350原装卡都七百多呢

评论

为了糊口而评测,参考价值就不大了.如果是中立评测其实可以这样,
首先,看着主板说明书读一遍元器件的评测方式一定要摒除.评测供电只需要做两件事情,
1)跑烧机看哪张板子的供电温度先到保护降频.
2)测试CPU和供电温度升高后电信号的波动幅度.
我从来没有看到有人评测主板的时候测试过这两项数据,但恰恰是超频最重要的东西.

评论

你这两项控制变量也太难了。。。而且测试结果在你的平台上可能几乎没有参考价值，比如有没有风吹散热片，区别就很大

评论

不好分辨哪个是原厂的，价格一千七的，2000多的都有，都声称是原厂。。。

评论
ITX单M.2不能接受，双M.2供电能力很失望，看来要等十代ITX了。
