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.

#10 Without XP64 only Linux apps can give great performance boost over 32 bits apps. Yes, I'm not a gamer, I don't care about UT2K3 or DX9 benchmarks.Anonymous User - Tuesday, September 23, 2003 - link
#19i agree. good review, and how anyone could see an AMD bias in that article, i have no idea. he fvcking said repeatedly that AMD isn't really cutting it with the A64/FX. the worst type of fanboy is one that cant read.
its sad to see AMD lagging like this... if they fall too far behind, they wont be able to compete with Intel on a high-end level at all - which sucks for competition.

That was a well written review.Anonymous User - Tuesday, September 23, 2003 - link
#15, doesn't the fact that you can buy an FX51 along with an Athlon64 3200+ at a variety of stores now contradict that statement? I mean someone even said they sighted them in retail stores and the sort across the world before even launch.Anonymous User - Tuesday, September 23, 2003 - link
For the non-fanboys out there, I have a couple questions.1. Is dual-channel really necessary for the Athlon 64? What is the bandwidth of the Hypertransport bus?
2. Anand contends: "Ignoring the performance boost Intel gains by going to dual-channel, OEMs demanded a dual-channel solution from AMD simply as a checkbox feature." Do you buy this? I thought CPU manufacturers pushed the mobo guys around, not vice versa.
3. After launching on two different Sockets (754 & 940) - is AMD going to convert everything over to 939 in '04, or are we going to see high-end on 940 and low-end on 754?
4. Where are the UT2K3 64-bit version benches?
5. I know it's kind of hard to judge, but how is the driver support for 64-bit coming along? (As a measure, does anyone know if nvidia and/or ATI will be ready with 64-bit drivers by the new WinXP64 launch?)
6. This is more of a mobo/chipset questions, but where does PCI Express/3GIO fit into AMD's hypertransport plans?

What i really dont understand is this: "AMD has lost a considerable amount of credibility" and again : "AMD has also priced the Athlon 64 and Athlon 64 FX very much like the Pentium 4s they compete with, which is a mistake for a company that has lost so much credibility"What exactly do you mean by that Anand?

#13The FX-51 will not be avaiable in any reasonable quanitities until next year. The availability of any succeeding products is pure speculation.

I think we'll see the athlon 64 outpacing the p4's in divx encoding once we see a 64bit enabled codec.Anonymous User - Tuesday, September 23, 2003 - link
All reviews (with exception of Toms Hardware and x86secret, go figure) show the FX51 outpacing the P4 Emergency Edition in the gross majority of benches. That's not even counting the fact the P4EE isn't even going to be available until November (making this a paper launch) and by it's availability the FX53 and Athlon64 3400+ will have already been out in the market with us looking forward to the FX55 in late 2003 or early 2004.Anonymous User - Tuesday, September 23, 2003 - link
#4 & #7. Please give me a couple of URLs (not thg) so i can validate your inspired response.
