Wii U has 2GB of DDR3 RAM, [Up: RAM 43% slower than 360/PS3 RAM]

Those same density limitations present themselves to Sony and MS as well. While Sony was rumored to be using 2 gigs of GDDR5 that'd be 8 chips. The largest amount of chips a system has had is the 8 chips of GDDR3 the 360 launched with. Getting more than 2 gigs of GDDR5 unified (unless launching after 2013 when higher density chips are available) is going to take anywhere from 12-16 chips.

That's a pretty damn busy board.

So either Sony and MS go with DDR3 in massive quantities, or they go with a smaller amount of much much faster.

The 360 has 8 chips? somehow I thought it was only 4 there as well. So that means it's using 16bit chips as well?

How much of gain in transfer speeds can you actually get from having more chips in a real life situation?

You know, this situation now kinda reminds me of those low-end to midrange graphics cards with far more (slow)VRAM than they really need:

But even this card has around 25GB/sec of peak bandwidth...
 
From what I can find the 360 has 10MB of eDRAM with 32GB/s bandwidth?

What are expectations of the Wii U's eDRAM. I've seen 32MB floated a lot. Any mooted speed?

The eDRAM on the 360 was on a separate die, whereas the rumour is the Wii U's isn't. So as well as there being more of it it also has much more bandwidth.

I'm thinking I mussed something up there.

No it started at 8 RAM chips, capacity doubled in a few years time and newer models only feature 4 chips.

You'll probably get a much better answer from someone else on speed differences.

So...I understand some of this stuff floating around in this thread, but with memory AND processing power being weaker than the current HD twins this really is just a Wii HD but with a tablet controller.

I was expecting at least a console that can stand up to the current consoles, not barely meet neck and neck. This is kinda disheartening. I'm not a specs whore in the slightest bit, but even this is making the nintendo fanboy in me is slowly die. Maybe Smash Bros or 3D Mario or Zelda or whatever Retro is cooking can revive that :(

What is Nintendo thinking nowadays?

Is it common to use different vendors for the ram when building a console? Please correct me if I'm wrong, but in the 2 teardowns that I have seen, one has had Samsung memory and one has had Hynix memory. Are they the same?

12.8

17 was a guess based on the maximum speed of the Samsung RAM (1066Mhz vs. 800Mhz). Anandtech unit had slower Hynix RAM.

At the time, PCPer didn't give the complete chip model number. 800/933/1066MHz were the listed available products in the manufacturer's document.

Now that PCPer's article is up, the photos indicate that their Samsung chips are HC12 speed grade i.e. 800MHz.

Yep. It's par for the course (PC graphics cards and DIMMs, of course).

And yes, they have the same specs.

We still don't really know anything about processor power.

I thought with the other impressions from before the release stated that the CPU would be a little slower? Even then...just damn. I guess I wasn't expecting the RAM to be this slow :/

I might wait til after Jan to pick a Wii U up tbh.

i know this has probably been answered countless times already, but why quadruple the ram amount when you halve the speed?

Well, it still gives you more space to work with.

If you design your technology such that you are mostly bulk loading your games (like say a Zelda dungeon or platformer level) this could still work fine.

So, if you had a very particular use case for how you tended to make your games, you might feel this is a fine solution even if it doesn't work that great for everyone.

becuz.

and why does the wii u OS need a 1GB of RAM, anyway? It's really inexplicable. The Wii U is starting to look like some really terrible hardware design. And according to Nintendo they're not even profiting on it.

Process shrinks allow higher density chips, but you're ultimately limited by the physical I/O ports of each chip. "Half-the-speed" is just a symptom of Nintendo choosing a 64-bit memory channel.

And ultimately, a larger bus just increases board complexity via increased trace wiring.

In 2005, GDDR3 had a max density of 512Mb, and each chip used an x16 bus (and clocks, but GDDR3 and DDR3 have the same throughput per clock anyway). In 2009, 1Gbit density chips were available for GDDR3, and each of those sported an x32 bus width.

8 chips x 16 = 4 chips x 32 = 128-bit bus connected to the GPU (512MB)
Actually, for dev kits, MS kept the same RAM config until the 1Gbit chips rolled around, so post-2010 kits were using 1Gbit GDDR3 with x16 width (1GB, 8 chips x16 = 128-bit)

Bus size does impose a minimum physical chip perimeter though (both DRAM and the IC it's connecting to). They could technically create higher density GDDR3, but keep in mind for consoles that you're staying to a fixed memory size in the end. A single 4Gbit GDDR3 chip would satisfy the 512MB of 360, but then the chip itself would need a 128-bit bus (lots of wiring in small area). The technology roadmap for GDDR3 ended ages ago anyway.

Oh, you were talking about purpose. Nevermind.

ah thanks. at least there won't be a whole lot of 'why doesn't the wii u get watch dogs/bge2/half-life3/mirror's edge 2/star wars 1313/bioshock infinite/atelier ayesha' threads.

There was a good post about this yesterday, but it sounds like Nintendo conceded way back in the GC days that the hardware arms race between Microsoft and Sony could only end in disaster for Nintendo, so they decided to do their own thing separate from the competition. Honestly from a financial stand-point it was and still is a good idea, I don't know how Sony is going to fare if they put out another high end money sink.

Yes but more sales ≠ more good games
look at the wii by your logic i should've been the console with an huge number of great games second only to ps2 and yet...

Well, and the PS1.

Hey the PS1 and 2 were pretty good, maybe there's some logic to this. 2/3 ain't bad.

The OS footprint needs to be cut down. It would help performance for newer games.
 
But that's factually incorrect

Take away the whole sending video to the controller thing and I'm not seeing any major selling points over the 360. Custom soundtracks? Party chat? On screen notifications? Streaming video and audio from your PC? Can I connect to the console with my iPhone or iPad? Can I queue up game downloads on the web?

I actually expect the CPU to be a bit faster*. Not that I think it's going to be super-powerful or anything. More that people under-estimate how terrible the PPEs on the PS360 are.

*in real-world use. It will have a slower clockspeed.

Ah well I guess I heard wrong then. I'm letting all these specs get to me I guess. It will still have great 1st party games as usual and a few great 3rd party ones like Rayman and Bayonetta 2 and etc.

I've had this thought that this is where they've been going since the Wii, which is like you said smart, but I don't think the success will be as easy as "woo Wii Sports!" like it was at launch 6 years ago. I've always had this thought that maybe Nextbox or PS4 would be too high-end systems for the regular gamer to buy that it would be better off anyway to get a PC since it'll surpass them by the time they come out anyway. I'm not sure, but It'll be interesting to see.

Don't forget achievements! And working multimedia apps!

And I don't think there's a photo viewer or MP3 player, either. Could be wrong though!

PC, plus a console of your choice depending on whose first-party titles you favour, is a pretty great combination to go with.

Actually, he's not. I mean, there are certainly a few new things here such as Miiverse that don't quite have an equivalent on the other two HD consoles, but other than those, Wii U isn't at parity with either one of them.

Just a few months ago I was thinking of going Wii U/PC for the next gen of gaming, but ever since getting Halo 4 and seeing how well 343i handled that, I may just get the Nextbox after all. Damn decisions! lol

My verdict is that unless you're a super duper hardcore Nintendo fanboy the Wii U cannot be your standalone system for the next gen, but I'm sure most of us knew that.

Umm, that is not how it works.

This is RAM to CPU/GPU bandwidth, data has to be loaded to the CPU and GPU many times a frame. This have nothing to do with loading data into RAM from the disc drive and being able to load more things into RAM does not make up for bandwidth.

That's good to hear. And honestly, if it doesn't hamper the next Zelda, 3D Mario and SSB, that's all I really care about, personally. Third party games are cool and all, but what's the point if they'll wind up being compromised?

Yeah. I'll get first party games and the random third party games that interest me. (Like Monster Hunter) but I'll have two consoles anyways .

Nintendo designed this system around their wants.

If any games are going to play to the systems strengths and hide deficiencies it is theirs.

Full stop, simply put.
