X570 vs X470

[Gerr]

I know what everyone says...if you don't need PCIe 4.0, no need to get X570.  However, I don't think it's that black & white.  Here are some of the areas I am wondering about...

 

Overall build quality:

Many reviewers say that OEM's didn't start to build high quality mobo's until the X570 line as AMD just wasn't popular enough compared to Intel.

 

Good VRM's:

The VRM's on many X570's are overbuilt while many are underbuilt on the X470's.

 

BIOS chip size:

Isn't there an issue with the size of the BIOS chips on X470 mobo's not being large enough to enable all features if you use a Ryzen 3000 CPU?  Not an issue on X570 Mobo's.

 

PBO & Auto-AC:

Are these any better on the newer X570's than the older X470's?

 

I am looking to buy a Ryzen 3700X in the near future for a gaming & H.265 transcoding system.  I have no need for PCIe 4.0, but am eyeing the Asus TUF Gaming X570 Plus or the Gigabyte X570 Aorus Elite mobo's.  For the same price, I could get the Asus RoG STRIX X470 mobo or save $50 and get the Asus Prime X470-Pro.  

 

Just looking for some INFORMED thoughts/suggestions.  Thanks!

Hardware unboxed shows(semi-speculates) that most of the differences are in the BIOS

 

The (currently) 85$ MSI b450 A-Pro runs with the best of them.

Just an FYI, many X470 and B450 motherboards can do PCIe 4.0 already with an appropriate CPU and GPU. My ASRock B450M Steel Legend does it with the 3600 and a 5700 XT.

The X570 motherboards are definitely better suited for the 12 and 16 core options. I mean look at it like this. The high end motherboards on the X470 platform were designed for the 8 core 16 thread 2700x maximum. There was no options higher than this, thus you have a situation where only two Asus motherboards in the X470 lineup able to comfortably handle 200 amps on the CPU. But why not? Because it's definitely not needed, not for 8 core, and 8 core was max.

 

With the 3000 series, AMD is doubling the core count. Previously, the highest quality power stage was the IR3555 60A on the X470 Crosshair VII Hero. Now, the lowest quality power stage is a SIC639 50A on the X570-P, but even then, there are two power stages per phase. The entry level X570-P can in fact handle the 3950x, comfortably. There is less comfort with overclocking compared to the most expensive X470 board, but it can handle it.

 

saying X570 only has PCI-E 4.0 is flat out wrong. Between MSI, Asus, Asrock and Gigabyte. There are only 3 motherboards i would absolutely not put a 3950x on. On the X470 platform, it's almost reversed, in that there are only a handful of boards that can handle a 3950x.

 

By the way, which Strix X470? The ATX sized F-Gaming is significantly better than the mITX I-gaming? The X470-pro is a good option as well for a 3700x.

 

 

TLDR: Because 3900x and 3950x exist. Almost all X570 motherboards comfortably supports them. Because 3900x and 3950x did not exist in 2018, few X470 boards comfortably supports them and only a couple have comfortable overclocking headroom.

who said X470 VRM's are "under built", just because X570 is overbuilt doesn't make X470 under built, it just means the entry level x570's are better then entry level x470, not that all x470 is crap. Shit there are x370 boards with VRM's just as capable, they where just higher priced.
