Xeon™ processors with Intel
®
EM64T requires a computer system with a processor, chipset, BIOS, OS, device drivers and
applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance
will vary depending on your hardware and software configurations. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be
available. Check with your vendor for more information.
Execute Disable Bit requires operating system support. See
http://www.intel.com/business/bss/infrastructure/security/xdbit.htm
for more
information on how to implement this feature.
The 64-bit Intel
®
Xeon™ processor MP with up to 8MB L3 cache is designed for high-performance multi-
processor server applications for mid-tier enterprise serving and server consolidation. Based on the Intel NetBurst
®
microarchitecture and the new Hyper-Threading Technology, it is binary compatible with previous Intel
Architecture (IA-32) processors. The addition of Intel
®
EM64T provides 64-bit computing and 40-bit addressing
provides up to 1 Terabyte of direct memory addressability. The 64-bit Intel
®
Xeon™ processor MP with 4MB L3
cache is scalable to four processors and beyond in a multiprocessor system providing exceptional performance for
applications running on advanced operating systems such as Microsoft Windows* 2003 Server, and Linux*
operating systems. The 64-bit Intel
®
Xeon™ processor MP with 8MB L3 cache delivers compute power at
unparalleled value and flexibility for internet infrastructure and departmental server applications, including
application servers, databases, and business intelligence. The Intel NetBurst microarchitecture with
Hyper-Threading technology and Intel EM64T deliver outstanding performance and headroom for peak internet
server workloads, resulting in faster response times, support for more users, and improved scalability.
