AMD plots an end run round Intel with SeaMicro's 'Freedom'


Meteoric rise ?!

SeaMicro was in trouble. They had a hard time selling their boxes for $250K a pop. No IT manager wants to make such a large commitment in one shot - they are used to an incremental scaleable approach. This is a good outcome for them, the alternative was a fire sale.

AMD did acquire them for their technology which is interesting - however this only works in the scale-out big-data space which is small considering the rest of the market where Intel servers play. AMD might recover their investment in this acquisition but this hardly helps them compete against Intel in the other segments.

Sounds to me more a story for Rory Read and Lisa Su to show their board that they are doing something.

Tilera routs Intel, AMD in Facebook bakeoff



It says it is a VLIW core, so it cannot be MIPS - some custom stuff.


Not a fair comparison

So I decided to read the published paper. It is not a fair comparison - a customized and highly modified version of Memcached running on the Tilera vs. the out of the box version running on the x86 boxes. One key modification on the tilera memcached code was to get the code to run on multiple cores without need for a single synchronizing point - the same optimization would help the x86 multi-core processors as well. The paper claims that they had to try our 100 different experiments on the Tilera to get the best performance. Imagine porting your code over to this architecture..!

And these are with old x86 processors - wonder how the comparison would be against the latest 4 socket 80 thread westmere processors..

SeaMicro pushes 'Atom smasher' to 768 cores in 10U box


Smaller and lower power but at what performance reduction?

Web servers, hadoop sure seem like the sweet spot - that would mean the Googles, Facebooks would be the target customers. Both of these however have standardized on Xeons/Opterons across the board. It remains to be seen if they would take the trouble of deploying SM in a few targetted portions of their datacenters. It would make sense if the performance and cost was substantial . Notice they mention 1/4 the power and 1/6 the space both of which relate to cost but I am curious to see what the performance reduction is. In the end it is all about TCO..



768 nodes is very impressive indeed. Although how many useful applications there are for such a large set of cpus with each cpu of which is a N570 which isn't very powerful. Webservers maybe but not anything else?

Having to think twice about what applications to run on an atom based server almost makes me think I'd be better off with a regular xeon based servers - at least I can throw anything at it and it is guaranteed to not come to a crawl because of single threaded performance not being up to par (?). I'd be curious to see any benchmark or performance data on the SM10000.
