Default New 'Leak' on Volcanic Islands

Apparently there is a new leak on

HTML Code:
http://wccftech.com/rumoramd-volcanic-islands-20nm-hawaii-gpu-architecture-leaked-512bit-memory-4096-stream-processors/
It reminds me of a photo I saw last year a long time ago which looked exactly the same

By idle.man5216 and he is on chiphelll too

So I say its fake, but the layout is very general anyway, and most of it is all known announced features of future processors. Also PCM's (Parallel Compute Module) and SMP's (Serial Processing Modules, which are supposed to be called LCU's and TCU's now (Latency Compute Unit and Throughput Compute Unit) according to HSA)

Also it looks a lot like Kaveri rather than Volcanic Islands (the DDR3 at the top), the small CU's and many Serial Cores, but you never know!

Yeah wow, it's the same picture, I did wonder why the 4096 shader GPU would only have 16 compute units compared to the 32 on Tahiti, seems like a wierd change of things. What's most telling to me is the fact that it's the same picture, just with inverted colors and turned 90 degrees.

This is obviously a hype. I wonder why people are devoted to these rumours, while the site has failed many times already as I remember. 28nm Richland, eh? Oland XT, eh? Venus XTX, eh? Rage3D seems the source, but the VI word is not from the quotes of the AMD executives. That is from the author's own words, and the author didn't tell whether this is a personal codename speculation, or the information told during the interview. Well, I feel a random codename picker was used when reading the conclusion.

As a reminder, by the way, the ACEs themselves are already a microcontroller configured to do the kernel dispatching and GPU managing works sufficiently - with their own set of special-purpose instructions. The CU itself carries a programmable scheduler to do their local wavefront scheduling.

Shall we stop day-dreaming, or saying things like every picture hides a tip of the fact? Period.

the image is an Opteron chip, or a HPC layout...

have 16 "bulldozer like" cores (or 8 modules if you like)
1024 shaders
ARM-A5 security chip
Trinity's UNB

strange things: (GCN 2.0 features?)
4 ACEs
UVD 3.2
VCE 2.0

Maybe this is Kyoto. With CFX, UVD, VCE and SAMU enabled on some versions? ex. Kaveri.

whats the meaning of this?

Doesn't look anything like a graphics card. 16CU of 64 cores each makes 1024. If this thing is real, it looks like its a HPC card maybe a competitor to what intel is making.

The DDR3 ECC memory kind of precludes a consumer GPU diagram, does it not? Honestly, why do people go to such lengths and why do others pore over every detail? Madness!
