Core2 can do macro-op fusion only in 16-bit and 32-bit mode. Core Nehalem can also do this in 64-bit mode.
"Time and again, processor architects have looked at the inelegant x86 architecture and declared it cannot be stretched to accommodate the latest innovations," said Nathan Brookwood, principal analyst, Insight 64.
A 2-bit index consisting of PCD and PWT bits of the page table entry is used to select one of four PAT register fields when PAE (page address extensions) is enabled, or when the PDE doesn't describe a large page.
The FNSTSW AX form of the instruction is used primarily in conditional branching...
Despite the dominance of x86 in the datacentre it is difficult to ignore the noise vendors have been making over the past couple of years around non-x86 architectures like ARM...
Once touted by Intel as a replacement for the x86 product line, expectations for Itanium have been throttled well back.

Figures 5, 6 and 7 also show the 32-bit version of WAS runs applications at full native hardware performance on the POWER and x86-64 platforms. Unlike some 64-bit processor architectures, the POWER and x86-64 hardware does not emulate 32-bit mode. Therefore applications that do not benefit from 64-bit features can run with full performance on the 32-bit version of WebSphere running on the above mentioned 64-bit platforms.
