It's more than enough. It's in fact at the cutting edge for what's feasible on these devices.
It's almost 3-4 times the performances, actually. 512 Gigaflops versus 2 Teraflops.

Aya Neo and GPD Win 3 are nice devices, but they run $900-1200, and I'm expecting the Steam Deck to be more powerful than either. A reasonable expectation would be something like Xbox One/PS4 settings at 720p. If you're so worried, don't buy it.

It's the biggest problem for Switch as well. Don't care about a handheld PC as there's no unique games for it, but I do hope Nintendo comes up with a solution for memory bandwidth next gen. At a minimum, an 128 bit bus will be needed. Split memory isn't ideal, but perhaps 2 separate pools of memory both with 128 bit bus width (like ps3). That or eDRAM, but that's getting too expensive nowadays.

The point of the discussion in this thread is that the 1.6TFlop GPU and 4c Zen 2 CPU is going to be severely gimped with only 44GB/s memory bandwidth provided the OP's suspicions prove true and the device does indeed only have a 64bit memory interface.
There is nothing, and I mean absolutely nothing cutting edge or "more than enough" about a system with only 44GB/s total memory bandwidth.
The PS4 which is 1.8TF (polaris) has 176GB/s total BW shared between GPU and CPU, and its CPU is weaker and will use much less bandwidth than the one on the Steam Deck.
The Nintendo Switch uses a max. 393GFlops GPU but with 25GB/s total memory bandwidth. The Steam Deck boast 4x the GPU performance but has (potentially) only 1.76x the total memory bandwidth.
I can't see how it can work.
At this point, I think i'm with
thicc_girls_are_teh_best
. They MUST be using a 128-bit bus. So maybe they have some chip configuration supplied by Micron or someone.

Switch games are made for the switch though. there is a big difference there. Witcher 3 will be a neat comparison as the switch is mainly hindered by is RAM there where as this thing has plenty.
I am betting this thing will produce performance slightly below a PS4 in real world use for most games. ANd that is mainly because of my experience with a laptop that has a Ryzen 5 4500U. Its not a great gaming experience and this handheld will have an even lower TDP to work with.
The key is that you get the scalibilty of PC gaming so even if say RED DEAD 2 doesnt look as good as the ps4 version you should be able to make it run better.

The 4500U has a GPU that is 2 generations older than the one in the Deck.

Well if your gonna play that game neither does the switch with its 32 or 64gb of storage included. Oh wait, there's sd cards for both, it's a wash in that regard.

The Deck GPU has a 25% better IPC thought... it is basically that old generation with 2TFs.
You can find bechmarks with AMD APUs way stronger than Deck playing games at low 720p, low 480p, low 360p... some not even reaching 60fps.

It's apples to oranges.
The Switch is a dedicated portable with games designed by developers with the device storage limit in mind. It also uses game cards that don't need a separate install on the internal storage.
The Steam Deck is a portable PC with no games designed specifically for it. It uses no physical media, so every game needs to be installed. Unless you're only playing smaller indie stuff, good luck storing more than one game on that 64GB internal storage. A huge swathe of PS4/XB1/PC games routinely weigh in at far more than that.

I've ordered the 64gb one. But I don't need aaa games on it. I've got series x and ps5 for that.
This is my easy way to play oldies and sort of new ish content without all the big clobber a desktop pc brings. I've already got 2 work laptops and a Perry one already. It doesn't need to have the balls deep nvme drive for me. So that option saves me a few quid.

Yeah, I didn’t even think twice, I have 200+ games on Steam alone, then 100+ on GOG and 10+ on Epic and a bunch I’ve forgot about on Origin and UPlay or whatever they’re called now, and finally 300+ on Gamepass, plus emulators. I could literally sell all other gaming systems and only play what I currently have on PC and never get out of games to play for the rest of my life.

Valve will have to to pay to get those company's to care and valve is known to not pay jack shit ever so yea gg on that front.

It can happen but that is not the ideia behind Desk... it is to play what you have on PC already... so games will target all PC hardware that include Deck.

Totally agree, the raw power is nothing, Switch is a console that has ports very well optimized for the fact of being a real platform. These notebook PCs, shaped like a portable console, are a frankenstein that doesn't make any sense, I really don't understand Valve with these weird experiments.

OK, I'm going to disagree here. I understand why you think that, but you're only focusing on the heavy games. There are SO MANY games that are not that large (new and old). Case in point, I'm currently playing Blood: Fresh Supply; Battle Brothers; Darkest Dungeon; Elder Scrolls III: Morrowind; Children of Morta; Banner of the Maid. All there are less than 5 GB. I mean, I would love to play Blood anywhere. Same with Battle Brothers. And then there are slightly bigger games I can install on a 64 GB version: Divinity Original Sin (10 GB); Disco Elysium (17 GB). I can have all of these games installed at one time on that version. Honestly, that is what I would want to do. If there is a game that is bigger, I'll either play it on PC or expand the storage. It's not that big of a deal.
This is fantastic device. I cannot wait and see what people will do with it in terms of emulators. Would love to play PS1, PS2, N64, Gamecube games on it. And the sizes of those games are not that big either. Exciting stuff really.

Depends on how popular it becomes. If it becomes a success it’s not an impossible scenario that devs make sure minimum requirements sits where the Deck is, just to get extra sales, but I wouldn’t bet on it. I think we need to accept that sooner or later we’ll bump into games that won’t run or even install and we’ll need Valve to release a more powerful Deck. But this is the norm so I don’t think much about it.

The performance is like Series X at 4K
Or so I heard. It must be true.

No. Valve only included a low quality SD port in this thing, that doesn't go any faster than 100MB/s. It is literally going to run at HDD speeds off the SD card.

Not really, likely half the people who own switch use it digital only. So 50%+ of the market still has the same small storage issue.

Does the 64 GB version have an m.2 slot? Apparently Gabe himself has said the internal storage is expandable, but the 64 GB one uses eMMC. If it has an m.2 slot, a 2230 style SSD can theoretically be installed to expand the storage that way.
Whether that will actually work or not (for any Steam Deck version) is unknown and depends on how they've configured SteamOS to do that.

It is 128bits... 88GB/s.
It is still low but twice better than OP 44GB/s.
Where is the source? Because Steamdeck official page says dual-channel.

I doubt you have any meaningful real-world data points to support your use case estimate.
Regardless, it's pretty irrelevant. On the Switch user have the option not to expand storage and they will be able to play pretty much every game.
On the Steam Deck 64GB version, expanding the storage is a necessity.
The website technical info seems to suggest so but it's not end-user replaceable:

They updated it... yesterday it was:
That confirms 88GB/s.

64 GB eMMC vs 256/512 GB SSD? The former is a slower standard, and drives below 256 GB get slower on top of that.

The GPD Win 3 uses LPDDR4X at 4266MT/s, but using a 128bit width.
That means the Win 3 has 4.266 × (128/8bytes) = 68.2GB/s.
That's 154% the bandwidth of the Deck.

Deck has 88GB/s.
It is a bit better than Win 3.

Agreed. If I was under 12 with no job and my parents decided to get me a Nintendo Switch Oled model over the Steam Deck. I would report them to a local child abuse authority.

Just out of curiosity I installed some games on my 10 year old SD. It can only read maximum 21MB/s. Sure, the load times weren't the best, kinda similar to HDD. But the games played perfectly fine after the initial loading. I'm sure 100-150 MB/s SD will be fine for most games.
Although Steamdeck is unmatched as a portable. There will be limitations folks and keep in mind this is just the first iteration. Since they are not mandating developers code for the specs of the first Steam Deck, Valve is free to release updated hardware at any time.
I fully expect a Series S caliber portable in a couple years (from Valve or MS). That's when I will likely join the party.

The whole point of DirectStorage is that it doesn't need coprocessors. The GPUs themselves do the decompression. I see no reason why SteamDeck shouldn't be able to take advantage if it's the SSD version.

Direct Storage reduces CPU use but it still uses the CPU... not the GPU.

Both Switch and GPD Win 3 uses LPDDR4, so that shouldn't be a problem.

There's no PS5 Pro unless... you time-traveled back from the future and slipped up...
