Will B450m bottleneck Ryzen 7 2700

[starcaptainSI]

Hi, new builder here

I’m building a system for video editing, gaming, and CADing. I plan on using:

 

Ryzen 7 2700

B450m DS3H (gigabyte)

RX580

16gb ram 3200

1TB HDD (will upgrade to SDD)

650 watt PSU

H15 Thermatake case

 

Will the B450 bottleneck the CPU and GPU? I’m using this B450 because I plan on upgrading the ram to 32gb later on, so I need the 4 dimms. This excludes ITX, so mATX is the next best thing. Should I chose a different B450 or another chipset completely?

If you plan to overclock then I personally would choose another board ATX form factor.

Your problem on the board is not the chipset, but the board itself being quite bad (weak power delivery, and as I heard not good at handlng 32gb memory at higher frequencies). MSI's B450M Mortar is a much better choice if you can't go all out for an ATX board.

 

for CAD use, make sure what GPU your application prefers first. For example. Solidworks prefers Quadro specifically, Geforce do bad, Radeon do bad, Radeon Pro also do bad (but not as bad as the gaming cards).

The VRMs, man. Think of the VRMs. 8-core CPUs draw a lot of power and that creates a lot of heat through those circuits. If you're planning on running stock, look into a much higher-end B450 board with better power delivery and heatsinks on the VRMs. If you plan to overclock an eight-core processor, start looking into midrange X470 boards instead. The power delivery on those is much better than what you'll find on most B450 boards.

No, that's just wrong. You can't generalize this. Yes, the high end X470 boards can (!) have beefier VRM circuits but that's about it. People should just stop choosing their boards solely by the chipsets when shopping for a Ryzen system. The differences between B450 and X470 are not that big and it usually affects only stuff like SLI capabilities, additional ports and so on. There are shitty X470 boards and good B450 ones out there and vice versa.

 

The issue with mATX on Ryzen is: there's hardly any good board out there. There are great ones for mITX and ATX but not so much mATX. The MSI B450m Mortar is considered as having the best VRM design for mATX - still surpassed by several mITX boards.

Would the Aorus B450 pro WiFi ITX work any better since it’s a higher quality board?

I did a lot of research on ITX b450 boards a couple of months ago.

 

MSI and Gigabyte B450 ITX boards are to be avoided: 4 phase VRM and bad cooling. Both these boards get very mediocre / bad reviews. (temps on the VRMS are out of control on the Gigabyte). Not saying they would "bottleneck" the CPU, but the temps are not good, and the features you get not great.

 

The Asus Strix ITX and Asrock Fatality ITX boards both have 6+2 phase VRM, which is good. The Asus has a true 6-phase, and the Asrock a doubled 3-phase. For the sake of temperature and overheating, they should perform about the same from what I understand.

 

I went with the Asrock board myself, no regrets. It is a very well reviewed board. It has very good feature set, good performance, and is reasonably priced. The Asrock board performs really really well. The advice that B450 would bottleneck a 2700 is B/S. My 2700X runs perfectly fine with PBO (automatic OC with overvolting) enabled. I get really good benchmark scores with it.

 

The Asus board has only these benefits over the Asrock:

- True 6-phase VRM

- Slightly better Wifi chip (dual band)

- M.2 slot on the front instead of on the back with the Asrock (more convenient)

- Looks better in my opinion.

 

The Asus board is WAY more expensive, so for me it was not worth the extra cost. Really happy with the Asrock.

 

Again, B450 does NOT bottleneck a Ryzen 2700(X), and you DONT need an X470 motherboard to get the most out of your Ryzen CPU.

 

Good luck!

Correct me if I'm wrong, But the B450 boards will only support a memory frequency of 3200 MHz if the RAM is overclocked. So maybe pickup a 3000 MHz stick then overclock to 3200.

[bowrilla]

The ASUS ROG Strix B450-I (and X470-I, both are identical) have 2 M.2 ports (one on the back, one on the front). They are indeed true 6 phase and can be regulated to up to 600kHz switching frequency (adding more heat!) for cleaner power. The MSI B450I Gaming Plus packs true 6 phases as well but has better Mosfets than the ASUS boards: 6xIR3555 instead of 6x3553. Gigabyte's B450I Aorus Pro WiFi comes with 4x IR3556. They are better to my understanding but it's just 4 phase. It's okay for 2700X OC but don't expect too much. AsRock's B450 Fatal1ty Gaming-ITX/ac and it's basically twin the X470 Fatal1ty Gaming-ITX/ac both double their 3 phases, the B450 version is apparently produced with either SM7341EH or just like its sibling board with the slightly better FDPC5030. Probably cost savings.

 

The best ITX board VRM-wise is the MSI B450I Gaming Plus, it's in the same league as the Asus Strix X470-F. There are only 4 ATX boards out there, that are even beefier (AsRock X470 Taichi with 2x 6 phases, Asus Crosshair VII Hero with 2x 5 phases, Gigabyte X470 Aorus Gaming 7 with 2x 5 phases and the MSI X470 Gaming M7 AC with 2x 6 phases).

 

VRM-Ranking for the ITX-boards is as follows:

1) MSI B450I Gaming Plus

2) ASUS ROG Strix B450-I & X470-I

3) Gigabyte B450I Aorus Pro WiFi

4) AsRock B450 & X470 Fatal1ty-ITX/ac

 

None of the boards is bad but VRM thermals will be potentially a bit higher on the AsRock and Gigabyte boards. If you want to OC your 8-core Ryzen2 (or even Ryzen 3 with higher core counts) I'd go with the MSI or ASUS boards. They're close and additional features may make a difference: 2 vs 1 M.2 ports and DRGB + RGB header on the ASUS board for example.

From personal experience:

For anyone out there with the ASUS board: I'd be careful with the latest BIOS update. I had to flash it back to the previous version because it sometimes just froze the system and the power button didn't work. I had to unplug the whole system to shut it down. And for the love of everything that's holy in the damn universe: stay clear of ASUS' AI Suite. That piece of software is terribly crappy and buggy leading to my fans revving up even though I'm at 30°C on the core or just shutting down the pump in my custom loop for no reason. Without the software it works reasonably well, but I haven't figured out how to increase critical temperature above 75°C in BIOS. Chose the board for the additional M.2 port, Intel vs Realtek Gigabit LAN and the DRGB header. Pretty fed up with the software hiccups to the point at which a friend and myself are actually considering to design a proper fan and drgb controller with USB interface to get rid of the software clutter and to have reliable control. MSI wouldn't be a better choice though I assume.

Well, anything above DDR4 2133 is an overclock. There's no difference between B450 and X470.

I've attached a build that I did for my friend in the Spring of last year for the exact work load you are considering:

 

AMD Ryzen 2700X w/ Stock Cooler

ASRock X470 Master SLI/AC Motherboard

G. SKILL Ripjaws V Series 16GB DDR4 3200 (2x8GB)

Samsung 970 Pro NVME 512GB M.2

EVGA Geforce GTX 1060 SC Gaming 3GB

EDGA SuperNOVA 650W 80+ Gold PSU

 

He's been more than happy with the performance he is pulling for the entire Adobe Cloud Suite including After Effects.

 

I would recommend getting the 2700X for the Wraith Prism cooler as he sits around 4.1ghz without an issue while he is working. The 2700X really doesn't need to be overclocked which is an added benefit to you.

 

The Samsung 970 Pro, at the time, was the best NVME to get for content creation for consumers. He does a lot of 4K content creation and he drops all of his current project data onto that drive along with it being his Windows and Application drive. He stores his other data on an external, as he already had that and needed to conserve money.

 

I ultimately pushed him to a Geforce because Adobe fully supports CUDA for hardware acceleration. I wish prices weren't insane at the time, as I would have rathered he have more VRAM as these apps benefit from more VRAM, but he is getting the performance he wants which worked out. If it were today, I would have pushed him towards a GTX 1060 6GB or even a GTX 1070 if possible. At the time, the GTX 1070 was the best card to drop into a content creation rig for price/performance, as diminishing returns are seen once you move onto the faster cards for content creation. Sure, Quadros and Fire Pros are certified for CAD and Content Creation, but you don't want to game with them. I think a Geforce is a perfect blend for both gaming and content creation. Though I love the Polaris GPUs, in this instance, you really want to cater to the software you are running.

 

So with all of that said, I agree with everyone else when it comes to motherboard choices.

 

Build to cater to your software. Sadly, CAD puts a wrench in that as @Jurruniosays, but I am not sure it'd be terrible when running it with a GTX 1060/1070.

Solidworks do much better with 1060 than with Intel iGPU, but that's about it.

2nd gen Ryzen start at 2666MHz for 4 sticks I believe, supporting up to 2933 on 2 sticks

No, it's no better in quality and a big shrink in feature set. If you dont have enough budget for a better board, get check 1st gen Ryzen 7s. losing 10% speed but can have a noticeable price discount.
