[QUOTE="osan0"]i dont necessarily agree with everything in the article (the choice of resistive screen has its advantages in terms of responsiveness. the controller is not a tablet..its a controller built for gaming not browsing dinternet) but nintendo do seem to have made some very odd decisions. also the stuff about extending the wireless range using Wifi is just wishful thinking on the authors part. its certainly technically possible but it would bring in more latency. the only legit complaint on the controller front imho is the poor battery. at least there seems to be plenty of room for a bigger battery...im sure 3rd party addons wont be long in their making. OS responsiveness should be fixable (i think there is a patch due in dec). neither the 360 nor PS3 OSs were ultra slim, responsive and reliable at launch. they have had 5-6 years of work done in them to improve them. however what on earth is in the OS to make it take up 5GB? That is truly massive. also why does it need 1GB of ram? I hope that requirement is also reduced over time. and on that note nintendos decision to stick with flash instead of a HDD that is easy to replace is also very odd and failing to provide enough power through the USB ports for external HDDs is a very poor oversight by nintendo. essentially the wiiu needs 3 wall sockets now. it should only need 1. I know nintendo were focusing on making the wiiu a low power (in terms of electricity usage) device but surely it would have been more efficent to have any external HDD and controller take power from the console rather than from extra plug sockets. from what we know of the internals i was initally critical of the use of DDR3L over GDDR5. however further research has made me rethink that as GDDR5 would have introduced a lot more latency. i also dont ever recall a dev complaining about memory bandwidth on any platform...they complain mainly about the amount. so the lower bandwidth compared to the other consoles may be a non issue. however whatever they have done to the CPU they seem to have really hacked it up. it looks like the design philosophy of the wiiu will be "do it on the GPU". not necessarily a bad thing but it will lead to some games having PS3 type multiplats as devs get their head around that. but did they really have to cut down on the CPU as much as they have?nameless12345
Overall, GDDR5 is faster e.g. Radeon HD 7730M GDDR3 (e.g. Dell Inspiron 15R) vs 7750M GDDR5 (e.g. HP Envy 15t-3209 TX).
Wii U has eDRAM to mitigate 64bit GDDR3 issue, but Xbox 360 also has eDRAM with faster GDDR3.
From http://www.youtube.com/watch?v=zruKwU_OrkE the results of BOps2 running similar spec as my laptop i.e. AMD Radeon HD 5730M/6570M with GDDR3 and 128bit wide VRAM beats both Xbox 360 and Wii U.
Wii U has only 64-bit memory interface?
If so, that may be the reason why it's underperforming in the multiplats (besides the slow CPU, of course).
I'm not liking what I'm hearing.
I thought Wii U will be a balanced and efficient system but it now seems it's full of bottlenecks.
Could be the N64 all over again...
From PC tech sites, Wii U looks to have 64bit GDDR3 i.e. four 16bit Samsung/Hynix DDR3 SDRAM modules, but there are other issues e.g. IBM's multi-core PowerPCs. http://www.anandtech.com/show/6465/nintendo-wii-u-teardown
To workout the CPU vs GPU VRAM issue, I plan to test CoD BOps2 with half of video memory bandwidth i.e. downclock GDDR3 to 400Mhz/800Mhz which simulates Wii U's primary VRAM bandwidth.
128bit GDDR3 @ 400Mhz/800Mhz ~= 64bit DDR3 @ 800Mhz/1600Mhz.
Also, Radeon HD 7570M (rename 5730M/6570M, 400 stream processors) has 64bit GDDR5/GDDR3/DDR3 memory. Treat Nintendo as any other PC OEM vendor.
Radeon HD 5730M = Radeon HD 6570M ~= Geforce GT540M = Geforce GT 630M
Remember, we haven't factored in Wii U's eDRAM.
