Tejas: The Way IA64 Should Go Mass
The code-named Tejas processor was meant to be a late incarnation of Intel Pentium 4 product featuring a massively-redesigned NetBurst architecture. The IA64 functionality and out-of-order execution that were meant to be featured by the part might be a signal for software developers for migration to the 64-bit chips with a kind of EPIC architecture.
After the Tejas, Intel planned to roll-out some more powerful offerings, including dual-core products, that should inherit all the capabilities of their father; but at the end the company decided to trim the IA64 capabilities and then killed the projects code-named Tejas and Jayhawk, a server version of Tejas.
Ace’s Hardware web-site has found some comments made by an ex-Intel engineer Andy Glew on a news-group, commenting the abandonment of the Tejas and Jayhawk:
“The Tejas project has been in trouble for years – in my humble opinion, beginning with when they decided not to make an out-of-order x86 chip that could also run Itanium code (by converting the Itanium VLIW to uops that could run out-of-order)...”
