Forums - Nintendo Discussion - Wiiu RAM 43% slower than PS360 RAM

PCPer did a teardown. Great stuff... they actually read off the RAM chip (SMRT!). There's only 4 chips.

Samsung K4W4G1646B -> DDR3 4Gbit, 1.5V, 800/933/1066 speed bins -> I'm pretty sure that means "DDR3-1600/1866/2133" data rate.

256Mx16 would imply 16-bit I/O per DRAM... So... 17GB/s at most for main memory bandwidth. They didn't mention the rest of the numbers on the DRAM, but they ought to have high res photos later.

Wii U: 12.8 GB/s, separate eDRAM pool
 360: 22.4 GB/s, eDRAM for framebuffer
 PS3: 25.6 GB/s main memory BW, 22.4 GB/s graphics memory BW, no eDRAM

So does that mean the WiiU is worse? can't understand this sorry, didn't pay much attention in my hardware class lol

yes...well at least that's what I understood from reading the discussion over at gaf

It's slower than the 360/PS3 RAM but probably covers up for it by having more eDRAM.

:/ so if this is not as good as the ps3/360 now then how far behind will it be when the nextbox and ps4 are out? or is this not really a big deal?



No wonder they invested in such a large eDRAM cache, that is pretty slow especially for a unified RAM pool.

keep in mind I'm no tech guy..so zarx or gaf would be a better resource for you on the subject. From what I understand however this is pretty bad. If the cpu related rumors are also true then this system truly can be on par or maybe slightly more powerful than the ps360. PS4/720 won't have to do much in order to get a significant leap over this.

Also graphic comparisons are coming out now for games like batman. I saw one comparison image that...I hope is doctored to bait others, cuz it looked pretty bad for wiiu.

This may also explain why so few games seem to be using anti-aliasing or 1080p ... from the Beyond3D thread Quaz51 posted this:

i don't think nintendo use the max chip frequency (because more failure and heat).
probably use intermediate 1866mhz data rate = 15Go/s.
X360 have 50% more bandwith (22.4Go/s). it's a bottleneck, WiiU game probably need max use of eDRAM for map and not just frame buffer. it will be difficult to use MSAA or 1080p...

Looks like Nintendo went for cheap + low power (they're obsessed with energy savings apparently, lol, can't have the system eat more electricty than an Edison light bulb for some reason).
