AMD Athlon 64 & Athlon 64 FX - It's Judgment Day

Business Application Performance
When we use the term "business applications" we normally think about computer users sitting in cubicles using their PCs as a part of their daily jobs - checking email, editing documents, flipping through presentations and such. It turns out that a good number of users outside the workplace use their PCs in a "business" oriented fashion, basically using their systems for email, web browsing and document editing.
The Business Winstone 2002 benchmark suite has been with us for quite some time and stresses multitasking environments that incorporate actions such as checking email, browsing the web, editing Word documents, Excel spreadsheets and PowerPoint presentations.
The nature of these tasks predominantly stresses the integer execution units of modern day microprocessors as well as their load/store units for memory accesses. Given that we're dealing with mostly integer code, a good deal of it happens to be filled with conditional branches (read: if action A then do action B). As we've seen in previous investigations, architectures with shorter pipelines tend to do much better with branch-happy code. So let's look at the results:
Here the performance advantage is clearly AMD; the shorter pipeline of the Athlon 64 combined with the large L2 cache and the on-die memory controller make the Athlon 64 a very strong performer under business applications.

#43 is a bit 486 DX style with 20 stages of pipeline up his crápperhole.Anonymous User - Tuesday, September 23, 2003 - link
ROFL@#36Dude the Athlon64 is a 32bit processor?....lol
Hey everyone...the p4 is a 16bit cpu with 32bit extensions.
Your an idiot #36. And this is coming from an Intel fanboy, so you really know your in the wrong.

Price is more important for AMD because they've had their successes mainly on the price/performance front. If they are truly trying to match Intel on price, that advantage is essentially gone and it'll be an even harder battle to gain marketshare.Oh and some of you fanboys mustve missed the PM forum. What the industry sees is completely different from what fanboys see.

Maybe if the intel & AMD both ran at the EXACT same clock it'd be fairer eh?I'd like to see more on the Opteron as I'm going to order 6 of them in November, thank the gods it's not my money.

FYI, in the LAME 3.93 MP3 encoding 32-bit vs 64-bit benchmark, you claim that 64-bit is 34% quicker when actually the graph shows it as 2/3.07*100 = 65% quicker.dvinnen - Tuesday, September 23, 2003 - link
Haha, this thread makes me laugh.1) The only thing Intel has that can toach FX-51 is the XeonMP, errrr, P4:EE. This processor doesn't start shipping for 2 to 3 months. I can understand including it in the review, but there should be some sort of disclaimer stating that this is a sample and may or not be reflective of the final product. The EE's also will only be released to the OEMs, so expect to have to pay VooDoo or AlienWare there outragous prices if you want one.
2) The Intel fanboys ADMITT defeat. They are already rationlizing it by saying wait for Prescott to come out. All prescott is is a p4 clocked to 3.4 ghz with "improved hyperthreading." "The 11 new intruction sets" won't make any difference for a year or so (kind of like 64 bit goodness that you are bashing). But I guess the added bonus that you can heat a small house with it is something that AMD can't provide.
And I wish people would stop complaing about the price. All new processors cost this much when they are first released. They'll come down, but not to the price of XPs for a while to come. The mobo costs will also drop drastcaly (past nForce2 prices?) over the comeing months beause of no north bridge and only a 6 layer PCB.

64bit with 32bit compatibility would be what Itanium does. AMD64 is still native x86 with the ability to use 64-bit registers, thats why it can still run 32-bit programs as fast/faster than current CPUs.http://www.anandtech.com/cpu/showdoc.html?i=1815&a...

#36The Prescott is the next generation in the pentium family. It's not like it's a P4 with an increased multiplyer. AMD is in trouble when the Prescott comes rolling around.
