After numerous delays faced by Intel"s Pentium 4 "Prescott" and "Dothan" processors, it is not really big news that Intel is pushing code-named Tejas processor into the second quarter of 2005, about half a year later than according to the original schedule.
Intel"s code-named Tejas microprocessor, the fourth-generation NetBurst CPUs, will have core-speeds at around 4.0GHz – 4.20GHz, probably a faster Quad Pumped Bus, tangibly enlarged caches (24KB L1 cache, 16K uOps Trace Cache, 1MB L2 cache [probably 2MB for 65nm version]), a more efficient branch prediction mechanism, a new set of instructions known as "Tejas New Instructions" as well as improved Hyper-Threading organization. In addition, the Tejas may enable long-awaited 64-bit enhancements to x86 architecture or may increase the number of executive units.
