*Update on Wii U eDRAM Speed* Wii U can produce same graphics as PS4/XB1?




I like this guy's video and explanation and while he is definitely wrong on the eDRAM part, the rest of it is pretty much the truth. The Wii U can do all the effects of the PS4/XB1 if the code is optimized and developed from the ground up for the system. Xbox 360 vs PC is a great example of console ports running badly or requiring a ton of overhead power on the PC in order to get those games running well.

Now about that eDRAM speed:

Basically the Wii U eDRAM is decently fast and could range from 51GB/s to 102GB/s (most likely the lower) but no where near 1000 GB/s. The 12.8 GB/s for the DDR3 memory combined with the fast eDRAM speed gives the Wii U at the lowest/worst case scenario a 64 GB/s bandwidth.

Nate in the video above seemed to only be referring to the theoretical performance of 1000 GB/s that the Playstation 4 could have been clocked at if Sony decided to put eDRAM in that console; nothing about the eDRAM that he mentions has anything to do with the Wii U only the fact that it has 32MB of it and that it's fast for what it is.

For more information on the Wii U eDRAM speed and details I just shared, you read up on it here: Link

of course it can the only reason there saying otherwise is XBONE AND PS4 CANNOT COMPETE WITH WIIU AS A GAMING DEVICE

so they start the dersnged nonsense of under powered LOL @ THESE MONGS

wiiu is doing 120 frames a second gaming 60 per screen mario 3d world destroys knack

mario kart 8 is on par with ps4s best looking games

this is not rocket science trying to hide behind power nonsense because your console is a joke with a silly camera or a dualshock LOL

wiiu has more fast catch memory n its gpu than any other on the planet and 1080p with 2x AA is 32mb exacly the size of wiius buffer memory

wiiu gpu has 35mb on there

ps4 has no such memory and a small cpu catch and 200ns latency main memory

wiiu is sub 5ns thts 40 x faster

ps4 is a pc and has the slowest memory of all 3 systems

wiiu is a highly optermized custom video gaming box with the fatest memory

gddr5 has only half the cpu performance of ddr3 in benchmarks

wiius cpu has as much catch to one core that ps4 has to 4 cores and its also directly linked to the gpu edram

wiiu renders ad processes from catch speed processor embedded memory AT LIGHTNING SPEED

ps4 has to read in and out to gddr5 at 200ns

wiiu off sets its AA to the edram and its post processing and its over draw

GFLOPS HYPE IS POINTLESS

you will hesr a ps4 fanboy say it has 4 x more main memory than wiiu

but you never hear them say wiiu has 9.5 x more catch fast processor memory

LOL

Nintendo made the right decision with their hardware as it can produce great looking games, just like ps4 and xbox one. Fanboys are having a hard time accepting that nintendo deserves a spot next to the other consoles.

NINTENDO DOENT DESERVE A SPOT THEY DESERVE TOTALY HUMILIATION AND DESTRUCTIONOF THE OTHER IDIOT SYSTEMS THAT ARE TO ANY NORMAL MINED PERSON NOT - NEXT -GEN


THERE BRANDS THERE NOT NEXT GEN GAMING THATS THE OBVIOUS POINT

EVERY SINGLE SO CALLED COUGH CORE GAME THEY HAVE WOULD BE BETTER WHEN OPTIMIZED FOR WIIU

THEY DON'T DO WHAT WIIU DOES SO THEY FAIL AS NEXT GEN SYSTEMS

THATS OBVIOUS ITS ALSO OBVIOUS THERE HOLDING GAMING BACK AND I FIND THAT DISGUSTING AND UN FORGIVABLE

PES PS1-2-3 -4 VE PES WII A FINE EXAMPLE OF CONTROLLER REVOLUTION AND EVOLUTION

fps again a fine example of controller evolution and revolution

ps4 is going backwards not forwards at all

i make it
70 minimum not lol 50 BIT RATE TO CLOCK SPEED DOESNT = 50 ISH AT ALL THATS BULL SHIT

AGAIN PEOPLE ARE MAKING UP THE NUMBERS

WHAT ABOUT COMPRESSION RATIOS AND HOW FAST THE OTHER POOLS ARE LIKE THE 2 MB EDRAM AND THE 1MB SRAM AND WHAT DO THEY ALL DO

THESE FIGURES ARE BASED ON HORSE SHIT AND NO ACTUAL EVIDENCE

this all sounds good but no one will believe you until we see games on the same level as ps4 and xb1. Seriously name one game on Wii U that has the texture detail as the characters in RYSE. i am not doubting what you are saying becuase i know Nintendo knows how to make great powerful hardware when they want to... but as of right now even though we have some great looking games on Wii U the console is just not performing on the same level as ps4/xb1.

Look WiiU is a beast in textures Shinen are using 4k/8k textures on Fast racing neo enough said google 8k textures and WiiU is the only console using them ???? plus this uses 16x the memory to use these textures on wiiu so please tell me a ps4 game using hyper real textures at 8k ???? google it and ps4 and xbox1 don't show up meaning no1 has entertained these textures on ps4 or xbox1 yet so stop making things up WiiU gpgpu does 8k textures and at 1080p native 60fps work it out so we have Donkeykong and Fast racing neo to add to the 1080p native games wiiu has already....and 1 uses 4k/8k textures.....

it cant be just 64GB/s, thats very low and ports wouldnt even work cause 360 has 256GB/s available ofr the rops since are in the same die with the edram

the only bottleneck is the return of data processed by the edram logic like the rops to the gpu, which stands for 32gb/s

just do the math and you see it doesnt work

imagine we have two people running from point a to point bm do some work and then return

at the beginning person 1can run at 32GB/s and person 2at 64GB/s, person 2 arrives 2x faster but must do a work that takes about 4x more time than person 2, so when returning both should get at point a at the same time. But, this is only if wii u is usion the whole bunch of 32MB of edram, which in ports clearly arent using all the edram, must likely they are using just 10MB cause ports come from 360, so wii u doesnt achieve maxium speed, just 3 times less the maxium speed, so you are limited to about 22GB/s of those 64GB/s


so no, it doesnt woprk thatway cause that bandwidth you tal about is for the entire 32MB of edram

remebertat must ports dont even squeeze the edram as shinen says cause when you port fro 360 you only have availble 10MB of edram, so obviously the bandwidth is even less. This could be solved iof the developers made a ground up game or at least rework the port to chnage thingin the code, but that takes time and money and effort

besides, shinen says that can achieve 720p with double buffering with just 7MBof edram with sigle pass, where is the 360 you need the whole 10MMB for this and use multippasses , meaning that 7MB of edram fior wii u should provide atleast the same bandwidth that 360 has for its 10MB to achieve the 720p

you shouldnt be surprised if has a bandwith of 500GB/s to 1 teraflop

gamecube flipper edram had a bandwidth of 10GB/s and that was only for 1MB of edram and a technology of 2000

http://www.segatech.com/gamecube/overview/flipper%20datapath.gif

the proble is that must third parties dont take profit of it cause is easier to programm for the main ram insteadof the edram and thats something that even sony confirmed and thats why doesnt use edram

besides, when doing ports is even ore unlike developers take profitof the edram

again i said show me a game i can "SEE" not something a developer has "SAID". it is what it is

Hey Metaldave,

I just read this new article this morning concerning WiiU hardware/power:
