T.

You forgot to mention that x86-64 support will require a new OS specifically written for that architecture, not to mention recompiled applications to take advantage of the x86-64 expanded register files, etc.

Windows OS is very important, applications are not as important. The bulk of apps will not be recompiled for 64bit target for a very long time, some will never be recompiled, because they don't need to be. This is a point I think you are very confused about.

But it takes just a handful of apps to make the demand for x86-64 machines explode. SQL Server and Quake.

Ten - re: 'Heh, and to think that the AMDroids said that no one will ever want to recompile applications."

What the Droids meant is that no one will ever want to recompile applications for a new Intel CPU - but EVERYONE will stay awake nights recompiling everything under the sun for a new AMD architecture.

Ten - Re: "we still haven't heard whether Clawhammer already taped out or not. You'd think that even the YUK Register would hear about it the moment the base layers are sent to the fabs?"

According to the YUK Wretchedster, Sledgehammer first silicon arrived last year and AMD has been sampling it since July or August of 2000.

AMD Sledgehammer samples ship By: Mike Magee Posted: 24/07/2000 at 10:31 GMT

Sources close to AMD have reported that first real silicon is expected for its 64-bit microprocessor, codenamed Sledgehammer, as early as next month. Engineering samples of the chip are already with large PC customers.

That news is likely to horrify Intel executives who were forced to admit last week that delivery of its Itanium processor slipped a quarter, due to unspecified difficulties.

One source said that AMD's "lightning data transport" (LDT) is the real key to the performance advantages expected when silicon samples ship.

AMD's 64-bit processor, which maybe should be codenamed Iceberg if Intel's chip does turn out to be the Itanic, will not require massive operating system and application software porting exercises.

According to rumours, and we stress there is no hard evidence for this as yet, within the community of chip architects in Silicon Valley last week, Intel is readying an alternative 64-bit platform in case it is forced by circumstances to follow AMD's strategy.

That work may be carried out by the group of Intel architects in Oregon who worked on the Willamette platform. As we have reported here previously, there is little love lost between that team and the Santa Clara based team which developed the Merced-Itanium platform.

One chip architect working for a third party firm said that if Intel decided to take this action, it resembled the i432 project the firm eventually canned, after it saw some light which made it invent the 8086 microprocessor. Two engineers at Intel managed to cobble together the 8086 in a mere three weeks. The rest is history...
