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

What "other half"? From the quote in the OP, that's it. 4 * 4Gbit = 2 GB.

What we don't know yet is how fast the eDRAM is.

... either I am confused or the majority of people in this thread are. Wii U does not have split memory pools, except for the eDRAM.
Ah, should've figured that, looked at the tl;dr version without even trying to put it together in my head.

Well, I kind of expect having MORE can, when used appropriately, balance out being a bit slower, but it will almost certainly not be much help against the next Xbox/PS.

I don't think he mean literally half in terms of capacity, like those in the speculation thread who thought there would be physically separate memory buses for games (GDDR5) and the OS (DDR3). I think he's just saying the main memory bus is only half the story when you consider the embedded memory's contribution to the overall design.

interesting, because i thought nintendo was big into having fast parts in their console even if they weren't the most powerful. kind of harkening back to the n64 and the supposed reason of choosing carts over discs due to load times.

it is "gDDR3," note the lower case 'g' -- I'm not sure what that means.
It's listed under gDDR3, there's a seperate category for GDDR3. What's the difference?
It just means it's DDR3 for graphics board integration (i.e. 1:1 tracing from DRAM to processor) rather than DIMMs. There are PC graphics cards that use DDR3, which would actually be considered "gDDR3", but hey... there's the naming confusion and all.

"GDDR3" is a separate technology altogether.

Let's hope they haven't cheapened out on their eDRAM and that it's more flexible than the type in the 360.

The setup's also important but yeah, odd choice of RAM.

We'll have to see what they are doing with the edram, as this is a fairly different choice for them as far as RAM is concerned.

The eDRAM will only be large enough to store the render buffers (frame buffer, some textures, vertex buffers, etc), 99% of the game will be on this slow as hell main memory.
Like many people said already, the difference to whatever Sony and Microsoft put into their new consoles will be brutal.

If this is correct. And the rumours on the CPU speed are also correct. Basically the only thing saving WiiU is the GPU.

The Xbox360 and PS3 out performs it otherwise.

So what effect does RAM speed have exactly? Faster texture loading?
First of all, there are 2 separate metrics of interest for memory (well, there are even more, but these are the most important): bandwidth and latency. Both of those impact a huge variety of algorithms and general things a CPU or GPU might do. Generally, bandwidth mostly affects the speed of streaming computations (like those you might find on a GPU or n a CPU using SIMD), while latency mostly affects code that traverses data structures in memory (e.g. lists or trees) -- which is a lot of what any program does. Basically, almost everything is affected to some degree by memory speed.

How much data can be used by game for example textures and how fast can it display.

For example Gta4 without mods on high with 1600x900 resolution takes more than 1GB of Vram.

What this mean is that Wii U can't play GTA4 on very high settings and games like Crysis2 on high is also out of question.

Nope. Textures don't require much bandwidth. Regular setups need fast RAM for shit like render targets, but those should be stored in eDRAM on Wii U as far as we know, so I don't think the bandwidth will be an issue. If developers use it correctly that is.

Ah, thanks.
