UPDATE: A Beyond 3D web-site forum member has composed a better-looking image of the leaked block-diagram, which is added to the news-story.

A block diagram released by a Chinese web-site shows an ultra-high-performance system-on-chip from Advanced Micro Devices that should offer rather extreme general-purpose performance, very high integrated graphics performance and plenty of memory bandwidth. The drawing may easily be a fake, a new illustration of Xbox Infinity SoC, a block-diagram of upcoming Kaveri-like accelerated processing unit on steroids, or an all-new new graphics processor.

The chip, which block diagram was published by ChipHell web-site is claimed to be code-named Hawaii graphics processing unit that has sixteen serial processing units (and eight floating point units), 4096 stream processors, 256 texture units and 64 raster operating units. While installation of general-purpose/serial processing units into graphics processors seems to be a trend (since Nvidia Corp.’s Maxwell GPUs will have ARM-compatible Denver CPU cores), it does not seem that this is the case of this particular chip. In fact, it does not seem to be a GPU at all.

Although the image of the system-on-chip is extremely blurry, it is evident (if enlarge, sharpen, filter it and then add some logic) that it has all the blocks that the next-generation accelerated processing units are supposed to have. The SoC has security co-processor (ARM Cortex-A5), AMD-V, AMD-P blocks, unified northbridge (UNB), system controller hub (SCH), HyperTransport links, PCI Express 3.0 lanes, CrossFireX interface, eight 72-bit ECC DDR3 memory controllers, display controller, eight Steamroller-class x86 modules (with two integer/SPU cores, one FPU and L2 cache), unified L3 cache as well as a decent GCN architecture-based graphics processing unit.



The chip could easily be a next-generation Kaveri-like APU for high-end desktops as well as servers with 16 integer cores, 8 floating point units, L3 cache, graphics engine with 1024 stream processors as well as eight-channel DDR3 memory controller with ECC (which should actually support GDDR5 memory as well, based on previously published information). The default Kaveri APU should feature up to four Steamroller cores (1, 2). While the "APU on steroids" should be very large, even when made using 28nm process technology, such a chip could easily rival Intel Corp.’s Core i-series “Haswell” microprocessors in terms of performance thanks to vast general-purpose and graphics processing capabilities.

Given the fact that 512-bit bus is a clear overkill for desktop and even server applications, the chip could be the APU of Xbox Infinity. The probability of this is pretty low since the chip has HyperTransport link, CrossFireX multi-GPU interface as well as ECC support, neither of which are needed for game consoles. At the same time, the chip does not seem to feature eDRAM or eDRAM-related logic.

Even though the chip seems to have all the building blocks of a modern APU, it may easily be a complete fake.

AMD did not comment on the news-story.

If this is indeed kaveri this will change the entire landscape of next gen apu's.

Only a fool would believe that this is kaveri. There is not even 1% chance

Are you aware how big the die size would be with such specs ? Something like that can't be sold as cheap as trinity or Richland. It is either fake or a sever chip.

And you know this how again? I never said I believed this I said if this is indeed kaveri meaning if this is true.

Who said it would have to be in the same price range as all the other apu's This could be AMD's Extreme Edition version of an APU.

If this indeed Kaveri, TDP might reach 150watts maybe higher at 28nm.
1 3 [Posted by: kailrusha  | Date: 05/10/13 06:15:51 AM]
This is surely a fake. I guess it would consume upwards of 145 Watts. The market for these types of processors is very small now.... the general population of computer users only access Facecrap, Twidiot and YouTug. Having said that, I (and certainly most here beside Intel fanboys) would be in this APU's target market if it were true and welcome its development as a halo for the AMD brand.

tell that to intel they still produce 1,000 dollar core I extreme edition cpu's.

Yep, Intel core i7-990x is a halo product. Intel has lots of money to burn in the marketing department. But the actual consumer market for this type of processor would be very small indeed. It's not a matter of if AMD can do it technically - it is a matter of if they can afford to do it too. I hope so. It would fit in nicely with their strong rebranding as the place to go for gaming hardware.
4 2 [Posted by: linuxlowdown  | Date: 05/09/13 11:23:30 PM]
Well those days of burning through money with intel is about to end in that sector since they have lost 25% or earnings so far this year mostly due in part to slow pc sales which is why they are suddenly shifting gears and heavily updating the atom for small devices.

Steamroller CPU, with the same amount of stream processors as a Radeon 7850 but with GCN 2.0 = Kaveri with over 2 TFLOPS of Single Precision compute power

HSA apps will take off, no need to buy discrete GPUs anymore, no need to buy anything else other than these APUs

I only hope this is true, it seems as though AMD is trying to make a CPU to end all.

Well, if the re-hiring of Jim Keller as head of AMD's CPU division is the 'Return of the King', perhaps he's taking a page out of Sauron's book by forging a CPU to rule them all. Only thing is, I didn't know their were any massive volcanos in Sunnyvale, California.

Seriously though, I think this is either one of the game console CPUs, or it is a server chip. The 512bit bus could make sense if they are using some sort of 'ring bus' topology (kind of like the Radeon 29xx's memory bus). There is an outside possibility of it being Kaveri: if so, AMD will be suddenly stomping on Intel's throat, most especially if they have the TDP down below 100W.

It is impossible to have such specs on 28nm and sell it to consumers for good price. The die size would be extremely huge, probably bigger than anything we have seen.

If AMD makes such thing, then it will be very expensive and it will be sold for workstations or servers.

Just one of these would register as 16 cores (8 bulldozer x 2"cores". Theres no way a console would need more power than one of these chips. This is meant for servers or is a fake.

For a while now, GF has projected that 20/22nm will enter production in 2013. If they also deliver the high density T-RAM caches projected for 32/22nm, there could be some interesting surprises.

Doubling the core count might be possible. However, I'm skeptical that they could do so while also including a massive GPU and eight memory controllers.
2 1 [Posted by: x  | Date: 05/10/13 08:13:13 AM]

Kaveri most definitely will be a game changer for sure. That has been understood for months now.

I don't know what the diagram actually is but my sources are stating that AMD has really gotten their programs back on track in a big way and that people are going to be quite surprised what AMD delivers in the not to distant future.

Kaveri will be 28nm from GloFo.

Not really it's not designed for that! Bat the even regular gaming parts from amd are over killing Nv's workstation & server parts in terms of open CL based agpu computing. The Nv's open CL support sacks so they are overwriting it! There are a big latency problem's in use of the external gpus for efficient use of AGPU compute! This chip cud solve this problem elegantly! Wi cud expect the pci cards whit two of this chips & large amount of GDDR5! That cud be the dragon to kill the Knight!

The thing i really don't get is why the all super servers in the past year where upgraded whit Nv based solutions? The AMD had a 0 implementations bi now in this field! Whit this & code XXL AMD cud win a big time! The Code XXL should goopensource a moment it's fully developed if they want a success!

No, AMD won't skip Sea Islands (HD8000). This one is due to compete with Maxwell in Q4. This is likely the flagchip since it would crunch an HD7990.

This is not a SoC. This is Volcanic Islands flagchip, HD9970. The next step in GPGPU preemption, along with Kaveri. Excavator as you would imagine, will 'fuse this' with Kaveri.

I'm interested to know how you know this as fact.
1 3 [Posted by: linuxlowdown  | Date: 05/10/13 08:47:56 AM]

OK this is the info i have.

This leak is just a part of the 2013-2014 platform from AMD.
In all cases the GPU will accelerate the CPU.

1. It will be build on 20nm just like Radeon 9970.
2. There will be 3 kinds of products :

a) Steamroller CPU - eight x86 modules, you use this chip on a motherboard and put a discrete graphics card, just like now.

b) Kaveri APU (four x86 modules + some GPU under 9770), that works with a motherboard - dual graphics working great.

c) Steamroller APU, with eight x86 modules + 9770 GPU (around 7850-7870 in power, same GPU as PS4). All in one SOC. Comes with USB 3.0, SATA, Display, Audio chip OR can be mounted on special motherboards. (not decided yet)

Same as PS4 but Steamroller cores instead of cheaper jaguar. It will play all games for the next 5 years just like PS4 will do on 1080p. Steamroller CPU alone is around the same as Haswell, but with the GPU push it will be many timer over Haswell.

So you mean to say they're skipping 28nm and going straight to 20nm for Kaveri? That would make competitive sense because Intel are so far ahead in nodes now, going to 14nm in the not too distant future.
2 1 [Posted by: linuxlowdown  | Date: 05/10/13 09:22:47 PM]
20nm-LPM process in 2013.
20nm-SHP process maybe in 2014 refresh.

So 20nm almost for sure (kaveri, Radeon GPU, Steamroller)

They already talked about 14nm with 20nm underpinnings in 2012 :

Thanks for the links. This is interesting news. I thought AMD were going to step down to 28nm due to lower costs and good yields. If what you say is correct, then this leaked APU design makes sense at 20nm. Instead of being 145W+, it is more likely to come in under 125W. Combined with AMD's gaming push as the killer app, they stand an excellent chance at capturing the crown from Intel after nearly a decade of planning starting from the ATI purchase. Congratulations Rory Read and the team, including the original Bulldozer and Llano engineers.

I would love to see a modular system of embedding graphics and memory together. Put the processing (CPU/GPU) closer to it's own DRAM and then attach SSD. Use a filesystem and OS that supports a distributed file system and upgrade as you go. Individual CPU cores are becoming so small and consume a few watts that you could stack them with DRAM if you have enough air flow.
