B550 Aorus Master - 14x 70amps Direct Phases ! 980a Vcore...insane

More phases, the better the power delivery for either high number of cores or very high overclocked with voltage or both ! Less chances of CPU speed throttling down .

More layers normally equals more complex engineering to minimise interference in the circuitry.

For gaming and more applications, your not going to see a difference between PCIe 3.0 and 4.0 ssd.
Flagship b550 match mid range x570 for having 3x m.2 slots are slightly cheaper prices so sorted in storage front

THIS!

I don't have any new info on B550 so I can't give specifics and I don't yet know price points. However, I just wanted to touch on a couple of things mentioned here.

B450 Tomahawk pricing, along with most other circa £100-200 boards has risen due to an increase in component costs...capacitors mainly..along with a weakening of the pound. The more aggressively priced the boards were (generally cheaper boards) the less able the manufacturers were to swallow this price increase themselves.

Unfortunately, you can't just look at the number of phases to judge the likelihood of power delivery limitations. I've seen boards from the same range, same manufacturer and the same number of phases perform considerably differently. The quality of the VRM's along with the cooling will have a big impact. @orbitalwalsh mentioned the current differences, this is a really good way to judge these factors.

PCI-E Gen 4 is a good "tickbox", a great "headline" but in real world performance numbers it's never going to be a deciding factor for me. Currently, you'd have to get your stopwatch out to have any chance of measuring any difference vs gen3. Personally I'd suggest that you look at the number of lanes/slots made available on the boards when making a decision on which to buy. Future expandability has always been a major consideration for me personally.
Also, early word was that the B550 chipset would not support Gen4, this would explain the lack of a chipset fan... so I'm left wondering if something was changed or whether third party controllers are being used. Currently I don't have an answer.

Where is A520 though

We've had absolutely no word on A520 yet.

& yes, GODDAMN some of those boards are pretty!

On B550 PCIe4.0 is the responsibility of the CPU, not the chipset.
i.e. GPU 16x and CPU-driven NVME 4x

Unlike X570, B550 doesn't support gen 4 from the chipset as those will be gen 3 hence not needing a chipset fan.

what are the actual implications of this? Will there be a negative or positive performance impact? Specifically with reference to the likely development path of games

Watch the upcoming GPUs start pushing PCIE 3.0 to become a bottleneck. If you're thinking of keeping your motherboard for Ampere/RDNA2 and their successors I would be buying a PCIE 4.0 compatible motherboard if I was buying today.

vis-a-vis X570 - where everything is PCIe4?

not much. the important thing is the game storage drive and the gpu, so as long as you have one of each (and use them), then you should be good to go.

the big benefit/problem is looking downward at B450 (rather than upward at x570), because I think the limited number of PCIe 2.0 peripheral lanes from the chipset would start to be a real problem has high-bandwidth I/O proliferates:

It just means that you can only run 1 NVME at gen 4 speeds and all the rest will be gen 3 and if your planning to go SLI with GPUs you may get a small benefit as they will run PCIE 4 x8 which is essentially the same as a PCIe 3 X16 providing of course you have a gen4 GPU.

No impact on games. Gen4 will have no influence on that side of things.

Not having Gen4 on the chipset means that the lanes will be limited to 24 and may be shared depending on what is fitted to the board.

i understood that future games development was leaning towards loading textures on the fly owing to the super fast speeds now available on SSD storage? E.G. The Unreal / Playstation 5 demo.

I appreciate it will make no difference now.

I'm yet to see any evidence that there's a significant difference between data transfer rates of Gen3 & Gen4 in the real world. The evidence that I've seen is quite to the contrary. Theoretical or even benchmarked peak speeds don't appear to be sustainable enough.

Besides which, game developers rarely limit their audience with forced, next gen hardware requirements
 
So... I was completely wrong. Not 50/55amps as found in the recently released Z490 but then went 70amps !!!!!

14 direct 70 Amos phases... No doublers !

In terms of VRM capabilities, it looks like AORUS has some impressive options lineup up with the B550 AORUS Master offering a 14+2 phase Infineon Digital PWM (70A), the B550 AORUS PRO offering a 12+2 Intersil Digital PWM with 50A DrMOS stages, B550I AORUS PRO AX offering a 6+2 phase Intersil Digital PWM with 90A Dr.MOS stages and finally, the B550 Vision D which packs a 12+2 phase Intersil 50A PWM design. The lineup consists of the following models which will be available at launch:

That's key to the PS5 and XB platforms, I think its fair to say you can't see it right now but then we don't have the new Samsung range yet and the games to take advantage of this new storage performance

Consoles are a single standard, everyone's PC is so different it would be harder to implement such a change. Also bear in mind most PC gamers don't even use an SSD for a game drive.
