Out of those sites, I tend to go for Eurogamer.
And they said this
In terms of available power, R700 scales up from anything from a low-power Radeon HD 4350 with 80 streaming processing units all the way to the HD 4890 that utilises 10 times as many. Optimistic speculation zeroes in on the HD 4770 as the most likely candidate for inclusion in Cafe, but our sources suggest that the overall profile of the GPU is much closer to the Xbox 360 - and we've even heard that in some applications it may even operate at a deficit compared to Xenos.
While this may come as a disappointment to many, it's important to remember that Nintendo has achieved incredible success in recent years through a combination of factors: new concepts that appeal to a mainstream audience, a price point that's "right" straight from launch, per-unit profitability from day one and not getting involved in spec wars with rival manufacturers. Wii - and perhaps Project Cafe - aren't consoles with 10-year lifecycles in the way that Xbox 360 and PS3 need to be in order to recoup their costs.

I hope that doesn't mean the Nintendo GPU lacks high-bandwidth emedded RAM. If it does, it won't match Xenos' 256 GB/sec internal EDRAM chip bandwidth. Would be very disappointed.
