Not sure if somebody mentioned it, but:

435$ in 10k quantity, 600Mhz-1Ghz frequency, 64 cores.

Anybody know instruction compatibility? x86? mips? ppc?
Sheet mentions "ansi C" and custom iLib API to program. ( no OpenMP? )
Looks like the SDK is Linux based, cannot see any Windows screenshot.

But i'm not sure if is targeted only to the embedded market or also for the PC.. I can see a PCI-X accelerator card too in the web page.

ps: Ouch, I think posted in bad forum.. wanted Hardware & Software Talk , feel free to move if you want, sorry!

Huh, is this a disguised GPU with CPU set of features? :LOL:
You can find a pack of 64 units/cores already in a GPU like R600, for the sake of counting.

Looks like a pretty close competition for SUN T2.
 
Barf @ VLIW MIMD. Gonna be hard to extract that 192 GIP/s peak rate... Gotta love that on-chip bandwidth though. Nice SOC approach. I wonder how this thing compares to Niagara II.

We should be seeing chips from Intel and AMD that look quite similar before the decade's out. Of course those chips will have ALUs that can handle floating point math and will be targeted at entirely different markets, but this is still a nice glimpse into the many-core future.

Unfortunately, it has no FPUs. Maybe v2...

I thought it had FPUs, but then read this.

Update: I originally speculated that the processors cores each had two ALUs and an FPU, but that's incorrect. A Tilera rep has informed me that each core has two ALUs. I've also briefly updated the relevant parts of the article with some new, post-launch information about the processor, and I look forward to posting a follow-up that goes into a little more detail on the microarchitectural and software aspects of TILE.

the Intel 80-core looks much like it and Larrabee probably will. it's becoming a bit boring.. why not use hexagonal tiles instead :)

Larrabee uses a ring bus, not a mesh. But yeah, as I said in my article, this looks just like Polars (80-core Terascale prototype). But the cores are general purpose.

Also, it's not really at all like a GPU, though there is a set of stream processing libraries for it so you could use it like GPGPU.
