In an editorial, Kevin Krewell claims that there is no customer demand for Sledgehammer.
He said he though AMD was placing engineering resources on the wrong opportunity and although he thinks Clawhammer will rapidly find a place, multiprocessing systems using 4-8 Sledgehammers may not do so well.
He asks whether any major OEM will actually build server systems using Sledgehammer, or whether any AMD customers asked the firm to build it.
He claims that the top five server companies have already committed to Itanium, or in Sun and IBM's case, to Sparc and to Power 4.
That, he said, is likely to squeeze Cray in attempting to target Cray, Fujitsu Siemens, SGI and Unisys. ยต
