IBM says it's 32-Bit

http://raidenii.net/files/datasheets/cpu/ppc_broadway.pdf

I suppose you think that the Pentium 3 is a 128-Bit CPU because it has a SIMD 128-bit Floating point register lol

http://www.ehow.com/list_7446473_pentium-3-specifications.html

 

The instruction set of the Broadway is 32-Bit it's a 32-Bit CPU


Why would I think something that I've stated otherwise many times?


Broadway has a 32-bit address bus and a 64-bit data bus.

You can't issue 64 bity instructions on a 32 bit processor.


CPU bits reffers to address space, not the floating point size/data size. Broadway is a 32-Bit CPU with a 64-Bit FPU, not a true 64-Bit CPU.

From the PDF I linked

Broadway implements the 32-bit portion of the PowerPC Architecture,
which provides 32-bit effective addresses, integer data types of 8, 16, and 32 bits, and floating-point
data types of single and double-precision.

 

From Wikipedia:

In computer architecture, 64-bit computing is the use of processors that have datapath widths, integer size, and memory addresses of 64 bits (8 octets) wide.

Without further qualification, a 64-bit computer architecture generally has integer and addressing registers that are 64 bits wide, allowing direct support for 64-bit data types and addresses. However, a CPU might have external data buses or address buses with different sizes from the registers, even larger (the 32-bit Pentium had a 64-bit data bus, for instance)

http://en.wikipedia.org/wiki/64-bit_computing

 

Claiming that Broadway is a 64Bit CPU is disingenuous as it does not have an 64-bit instruction set, does not have a 64-bit address space and does not have a 64-bit intiger unit. Lots of 32-Bit CPUs have 64-Bit data bus and or a 64-Bit FPU.

 

if i remeber right the core in the wii is a 3rd generation custom build off the 740/50  seires of chips         looks like i shuld have said 750CXe  were in G3 powerpc from apple back in 98-02   2001 and imac  it was a 32 bit chip with a 128 bit vector core ripped out and a few other changes, i dont remember ever reading that they moved it to a newer family of chips so it stands to reason if its still based on the 740/750 and just a 3rd revision custom it would still be 32 bit.... though i dont know why they would not go after a new core alnog the lines of what ms/sony has or  a newer member of the power family the 740/750 the made very good strides in low power is quite antiquated 

 

edit 2 altivec is in the cell damn did not know that, i wonder how many games have used it

I'm still of the opinion that "three Broadways" outs this as fake.

Why in the world would they beef up a CPU based on 1990s technology when it would be much simpler to just to use a modern one, even if it's not the most powerful one money can buy? (Easy backwards compatibility I suppose, but really, doesn't seem worth it) It's like tying three horses together and feeding them steroids instead of just buying a damn car.


Well to be fair it says 3 "enhanced Broadway" cores, enhanced could mean anything including TBH including adding some Power 7 tech to it. Not to say it is real, but IBM did say that it was a custom CPU with tech from Whatson/Power 7. It could be that Nintendo got IBM to create a custom CPU derived from Power 7 but with Broadway feature parity for hardware backwards compatability. If the enhanced Broadway stuff is tru I don't think it would literally mean 3 Broadway cores. 

I guy on GAF who had aparently been mod verified as having access to a Wii U dev kitt said that the term "enhanced Broadway" was used in technical documents from Nintendo. http://www.neogaf.com/forum/showpost.php?p=41438117&postcount=195

Could it still be considered a Broadway, enhanced or not, if they aded POWER 7 tech to it? I mean, we're talking about a chip effectively built in 1998 here. Even with 3, wouldn't you have to virtually rebuild it to get it to run a game like Assassin's Creed 3? To stick with the three horses analogy, no matter how many steroids you feed them, they couldn't tow a semitrailer.


Likely they would be closer to power 7 I would think, it's definately got the Power 7 cache and likely the added SMT capabilities, out-of-orderinstruction execution etc. Just with the Broadband's custom instruction set extentions, DMA, etc for backwards compatability. At a wild guess anyway IBM said it was a custom CPU bassed on Power 7 tech so it makes sense for Nintendo to have had it customised to support all the features of Broadway for backwards compatability. While also adding the advanced features of the more modern CPU. 


Looks like Neogaf guy is a fake because most of what he said on there contradicted a lot of what was said on direct.

I believe there using a Power7 like IBM said but has properies of Broadway to have backwared capiabilities.

Uh, no. What the neogaf guy said was pretty much the same thing said by Iwata.

1GB main system memory for games. GPGPU.

The source for that leak even went into that thread and said the info was incomplete (they left out memory for the OS).

According to the Japanese Nintendo Direct 1GB FOR THE OS!!!???

And people said 512MB was absurdly high.
W...T...F...


Probably Nintendo over compensating for the multitasking and whatever else the system will be doing.

2GB total RAm makes me happy, cause I have no doubt they will eventually free up some of that 1GB for the OS towards gaming software.

And Iwata confirmed GPGPU. YEAH!


You realise that the Xenos in the X360has GPGPU capabilities right?

Shitty GPGPU capabilities. =p

And the reason why this is good news is that when it was suggested that WiiU would have a GPGPU people were like, 'lol, no Nintendo sucks'. So yeah...

Oh did you just compare 2003-4 GPGPU to todays one....

Doesn't take rocket scientist.

 

If you notice when people press questions on him he gives a very vage answer.

The guy isn't legit he is a guy trolling.

 

People know him for this and PEOPLE EVEN COMMENT ON It yet you still believe he legit? 

 

shhh

I'm just pointing out it's not really surprising, only people who had no idea about tech thought that the Wii U GPU wouldn't have some GPGPU capabilities. And GPGPU doesn't realy mean much on it's own.

No I am pointing out that GPGPU capabilities have been arround since last gen so it's not surprising a more modern GPU would have those features as they have been standard for 6 years.

I thought 512MB was reasonable because I believe that all (non-game) applications will be run in OS memory and these can probably run as background processes ... 1GB does seem extreme to me but I expect they're over-estimating and may scale that back 12 to 18 months from now.
