Today, we at Sun had a server announcement, and so did IBM. Get yer hot links & pix here.
If you want the official story, there’s Scale More With Less on the Sun site, and it’s perfectly harmless. But fortunately, the engineers organized a blog flurry with linkage aggregated by Allen Packer in Sun’s CMT goes multi-chip which has as much geek-level detail as you can possibly handle.
I’m in California today in meetings on the Sun campus, so for the first time I wandered by an actual launch event, which involves free food and beer. Sun’s campus is usually mostly pretty quiet, with the engineers holed up either in meeting rooms or behind their screens, but the launch drew a crowd:
I was amused that the food, and beer even, was lightly patronized, but the Sunnies had their hands all over the hot iron:
That’s 16 8-thread cores at 1.2GHz in 1U (or at 1.4GHz in 2U), which is to say a whole butt-load o’ cycles in not much space.
Wow, those T2 Plus processors are supposed to be about low-wattage, high-efficiency, but that’s a lot of copper glommed onto each of ’em. Which brings me to the competition. You gotta give IBM credit for independent thinking. Resolutely ignoring the many-core low-GHz trend exemplified by the new T2 Plus, they’re shipping a 5GHz part. Yeah, water-cooled, no shit; I’m wondering what all the pumpage and pipeage and so on must look like, and how many watts one of these suckers pulls. I totally think that’s a dead end in processor architecture, but still, it’s heroic engineering.
