Opteron, Athlon 64 and Athlon 64 FX processors
Disable/No Execute (NX)
Technologies for 2004
in November: Nothing major to report except that the 64
bit AMD processors now go up to 3800 (that still not a
Opteron, FX51, Athlon 64 etc have now become fairly established.
Please read this
article we posted a few months ago on the latest
of today Athlon 64s start at the 3000 and go up to 3400. Note
though that these aren't clock speeds. FX-51s are currently the
fastest of AMD's 64 bit processors but they use motherboards
different to the ones required for other Athlon 64 CPUs.
Technologies for 2003

developments at AMD
processors now go all the way up to AMD's XP 3200+, and their
dual-processor CPUs go all the way to the Athlon MP 2800+.
However, there is some unrest in the IT press about AMD's
numbering system. In the earlier days an XP 2000+ did compare with
Intel's Pentium 4, 2.0 GHz in performance. With the faster AMD
processors the "Intel Equivalency Numbering" is looking
unrealistic. The XP 3200+ seems to perform on par with the Intel
3.06 GHz Pentium 4, or below. It does not compare with an Intel
Pentium 4 3.2 GHz processor.
it's Intel's faster bus speed or the new technology - hyped under
today's new buzz word: "hyperthreading" - the fact is
that Intel is moving ahead. Intel's dropping their insistence on
the more expensive RD RAM and allowing motherboard manufacturers
to build boards that support the Pentium 4 using cheaper DDR SDRAM
memory modules has also made Intel the preferred option of most
technical/review websites. AMD though does remain the lower cost
option, and speed isn't everything.
course, the only constant in this business is change. There is the
new AMD processor called the Opteron on the horizon. It promises
64 bit processing (as opposed to 32 bit at the moment). While
hardware that handled 64 bit applications has been around for a
while this is the first time that a platform supports both 32 bit
and 64 bit processing and will be targeted at the SOHO market.
Most home users won't benefit for a long while as there aren't any
64 bit applications for the domestic/small business market. In due
course that will change. And Opteron will be available for
purchase. And Intel will be on the verge of announcing another new
technology/advantage in the leapfrog game to have the fastest

Front Side Bus (FSB)
our last update nothing much has happened. Oh, yes, there have
been some new processors, like the XP2400+, XP2600+ and XP2700+.
But not much else. Except that some of the newer processors will
be shipping in a 333 FSB (not 266 anymore) so you need to ensure
that your motherboard supports that. Of course most of our PCs
already support 333 MHz, any many of them support even the 400 MHz
FSB (for future upgrades) via the VIA KT400 chipset, nForce2

the release of Windows XP there has been a rush to cash in on the
"XP" bandwagon, and AMD is no exception. They've named
their new processors the "Athlon XPs". (Note though that
there is no connection between the XP processors and Windows XP.
You can run Windows XP on an older AMD processor and you can run
older versions of Windows on an Athlon XP processor). These XP
versions of the standard Athlon processor offer little difference
in technological advancement, but a big difference in marketing.
The Athlon XP processor, unlike all previous AMD processors, are
numbered strangely. It's unofficially called the "Intel
equivalence numbering". For example an Athlon XP 1800+
processor is really a 1.53 GHz (the 1800+ is meant to signify what
Intel Pentium processor you would need to compare it with). An
Athlon XP 1600+ is a 1.4 GHz processor. This numbering system
still has the potential to mislead, so be careful. An 1.8 GHz
processor is obviously a lot faster than an Athlon XP 1800+.
motherboards that take the standard Athlon processors also take
the Athlon XPs as they are the same shape and have the same number
of pins. The XPs still work on a 266 MHz FSB, and still use DDR
SDRAM. Newer motherboards for the Athlon support a 333 MHz FSB...
and RAM is now available that runs at this speed. It's commonly
referred to as DDR SDRAM PC 2700. At time of writing this article
the fastest AMD processor was the XP 2200+. AMD don't seem to be
planning any 333 FSB processors in the immediate future.

motherboards like the Asus A7V do not support the latest type of
Athlon Thunderbird processors and the latest fast DDR SDRAM. It's
not just a matter of speed. Please note that if you buy a PC with
the Asus A7V motherboard we do not guarantee that, outside of the
warranty period, you will be able to get replacement parts or
upgrades. For example if the processor goes faulty, or you wish to
upgrade it, it is not a simple job. You would need to throw away a
perfectly decent motherboard and RAM and buy a new motherboard and
new RAM to support the replacement processor. This could make
potential upgrades/repairs very expensive.
MHz Frontside bus:
intentions seem to be to move all Athlon Thunderbird production to
the 266 MHz Front Side Bus (FSB) i.e. a 1 GHz processor
will run at 133 MHz FSB x 7.5 multiplier (133 x 7.5 = 1000),
rather than the older 100 x 10. And it will run faster even though
it is still a 1 GHz processor. The physical shape of the processor
will still be the Socket A format. All production of standard 200
MHz FSB Athlon/Thunderbird processors will cease.
motherboards like the Asus A7M266, the Gigabytes GA 7DX etc will
support the newer FSB. The three new motherboard chipsets (as of
29/01/01) supporting the 266 MHz FSB are Via's KT133A, AMD's 760
and Ali's Magik 1. Other motherboard manufacturers are bringing
out motherboards based on these new chipsets.
If you bought an Athlon PC last year based on
Slot A motherboards like the Gigabytes GA71X, you can't now
upgrade the processor because all Athlon processors are in the
Socket A format, and not Slot A. Similarly, if you buy a PC today
based on the Socket A 200 MHz FSB (like the Asus A7V) you will not be able to upgrade
the processor if AMD moves all their Athlon processors to a 266 MHz FSB,
as they intend to. Today's latest technology for motherboards is a
motherboard that supports the 266 MHz FSB and DDR SDRAM, like
the Asus A7M266.
Anything else and you may find, in the future, than you can
upgrade neither the processor nor the RAM.
from the obvious advantage of a 266 MHz FSB some of the newer
motherboards support the new 184 pin DDR (Double Date Rate/Double
Density) SDRAM. This RAM
offers speeds of PC1600 and PC2100 as opposed to the older SDRAM
speeds of PC100 (800 Mb/sec maximum bandwidth) and PC 133 (1050
Mb/sec max bandwidth). With the speed of RAM being the major
bottleneck in today's PCs based on very high speed processors, we
welcome the arrival of DDR SDRAM. It is going to be a vital
component that will allow us to get a lot more performance out of
more technical news we've compiled a list of sites worth visiting:
new motherboards for the Athlon Thunderbirds will now also support
UDMA 100 for the IDE Hard Disk as an integral part of the
motherboard chipset functions and without the requirement of an
additional controller (like the Promise Controller on the Asus
A7V) or additional PCI card.
look out in our products section for announcements of new models
of PCs based on the new motherboards/processors.
