hey vortigern_red:
I read most of ur reponse and must of the response are from u.
I guess you can say i'm a new PC geek. I just bought me a new Super
Alien turbo case and i don't know what motherboard and processer to
get. I'm thinking about getting one of the AMD 64 family. either the
51,34,32,30, but after reading all these peoples review. I have a
hard time choseing. Any help me plz. I'm so fustrated with this very
old comp. Thank you

M8 that is the most crap i have herd in a long time, Yeh sure almost
everyone has badmouthed the amd.
CRAP Y Have u LOT EVEN USED IT????!!
The amd 64-fx kicks P4 3.2 and is about equal with the p4 EE, so
that is something u lot should respect. UT2003 has proven a worthy
benchmark for the amd 64-fx as it whooped p4 3.2 and the p4 EE by at
the most around 18% meaning that the athlon has the slight gameing
advantage, which if I had the money I would be quick to jump on!!
Think xp +3200 *3 which totaly rules.
1mb l2 cach, 2gb 3200 ram avaliable and so on.
Lets just hope things get better!

Remember when the Pentium 4 was released...hmmm, it was slow and not
much faster than the Pentium III. The Athlon was really a lot
faster at that time. However, the Pentium 4 core was ready for
speed and look at the chip now. All you guys trashing the AMD chip
should wait with your comments until we see what the chip can really
do in the near future. It is obviously much faster than any Barton
chip and is equal to any Intel chip on windows. Remember this is
the first release and there may be many more tricks AMD has for this
chip like clockspeed and hyperthreading in the future.

I agree on the disapointment, the 64 wins some and loses some. Not
the kind of performer you'd need to get back to top. In the glory
days of Athlon, It left the Pentium clearly behind in all
benchmarks. Now it only got from worse to competitive. And that's
only with the FX version which costs like #@#!.
Luckily this doesnt concern me. I buy in the mid range category and
the desision is clear as day. I wont be paying 1/3 more for a
Pentium that is lot less faster than it is more expencive. Plus the
FSB800 Mobos for Pentium (need this FSB if u want the winner
Pentium) are more expencive than Athlon mobos (FSB400).

what kind of multitasking are you talking about? surfin the net and
checking your email? i hope not. Unless you actually run a
process, like a batch file, calculations, or any kind of work in the
background, it will not help you much. I hope you don't mean that
multitasking for you is having more than one application open, like
word and IE.

Do these new 64's have some sort of HypterThreading technology? I
find that highly useful since I'm always multi-tasking.

Gandley: What on EARTH makes you think the FX-51 outputs 90 watts?
AMD designed the heatsink with a max, WORTST-CASE dissipation of 89
watts, and that INCLUDES future, higher-clocked processors. The 51
outputs much, much less. Think 60 watts here compared to the P4ee 94
watts.

Somewhat disappointing, but if amd can scale up production/clock
speed and reduce their prices they'll be in good shape. The p4
extreme does win most tests at 3.6ghz 3200+(2.2ghz) clawhammer bc of
its huge 2mb l3 chache, but it seems imo to just be a xeon for the
house hold paper launch, since it came out of the blue and no real
details of its release are out.

I still see a huge problem that hasn't been addressed by AMD yet.
The L2 cache bus, is very obsolete and has been a problem for AMD
for 5 years. You see intel has an eight way associative 256-bit
advanced transfer cache. AMD's cache is good because it is 16 way
associative but it only has a 64-bit path. This worked well back in
the days of the P4 Willemette chip and even the old northwood
because Intel had an inefficient Quad data rate memory path which
didn't work too well with Rambus, SDRAM and early DDR memory because
the path wasn't efficient enough to handle the memory of the day.
Fast forward to 2003, intel has finally been able to optimize its
data path and fill its L2 cache effectively. AMD is still using a
64-bit path to connect the L1 and L2 together. The memory
controller is filling the L2 cache with more than enough data but
the L2 cache still doesn't deliver the data to the L1 fast enough.
Here is what AMD needs to do and has needed to do for sometime.
Make the data path atleast 128-bit if not 256-bit. If data path had
been 128, the Athlon XP would have crushed the P4 northwoods, HT or
no HT. Because it would have taken care of a bottleneck and had
double the rate of data to the level one cache. The CPU die would
have been a little bit larger but still small compared to the die
size of a northwood. As it stands right now they have a great
memory delievry system to the L2 cache but the L2 cache can't get it
fast enough to L1 to be processed. I estimate even by double this
width you'd see a 2 fold or more increase in memory performance.
All AMD needs to do is double the bandwidth between L1 and L2 and
thats what enthusi
