Order Entry Results
Our Vendor test has received quite a bit of interest from certain processor vendors; rightfully so, as the workload is quite difficult to recreate.As you can see from the results below, there are some interesting conclusions that you can draw:
- The Dual Opteron 875 took the lead by 18% over the fastest Quad Intel. This should come as no surprise as we have seen in the past that the memory bandwidth limitation of the Intel FSB architecture does not allow the quads to really stretch their legs. On the other hand, the Integrated Memory Controller of the Opterons allow them to pull ahead.
- The additional L3 cache of the Quad Xeon 3.3GHz allows it to outperform the Quad Xeon 3.6GHz by 16%.
- The Quad Xeon 3.6GHz with the 667MHz FSB is only able to outperform the Dual Xeon 3.6GHz 800MHz FSB by 5%.
- The dual Xeons are able to outpace the dual 252's by 2%, and the single 875 by 5%. The Xeons success here can be attributed to the additional L2 cache.
- The Dual Opteron 875 demonstrated nice scalability by servicing 52% more requests in the same period as the single Opteron 875.

Sounds like computing could change a lot in the next 6 months.I can't wait to get my hands on a dual core chip - that type of multitasking gaming performance is what I've been waiting for... 92% of unfettered performance during Doom3? That's unbelievable.

Another thing to consider is that the 939, and 940 Dual Cores work with old mobos. so that saves upgraders ~$100 for the mobo (I have no clue what PD mobo's are going to cost) plus the cost of DDR2 ~$100 for 512MB, not true if you're going with the PD. So if you own a 939 a 2.8 PD will realy cost you ~$441, 3.0 -$516, 3.2 ~$730.Throw that out the window if you're starting from scratch however.

Great review very detailed, I have one caveat, and I should preface it with the fact that I own 4 systems, and all of them have Athlon 64's or XP's.That being said your "Multitasking Scenario 2: File Compression" Seems to be misleading, and identifies the A64 as the processor of choice in the 2nd portion of the analysis.
Maybe I'm wrong but from what I understand with how the test was performed you archived the file, got the amount of time it took to archive the file "x" for instance, and then figured out how many emails got imported in time "x" now because some processors took longer to create the archive than others they had more time to import emails. so in order to make this data more reflective of the performance of each processor you need to divide the number of emails imported by "x", and get e/s. The modified graph should be
PD 3.2 =19124/5.08 or 3764.57 e/s
A64 X2 =21687/6.25 or 3469.92 e/s
PEE 3.2 =16875/6.65 or 2537.59 e/s
AFX 55 = 3800/5.88 or 646.26 e/s
These corrected numbers show that at least in this test the PD 3.2 is the winner by ~8%

At that prices, most of the users really won't need their current mainboards for new dual core processors. I would prefer to have lower priced single core than that prices on dual core.blckgrffn - Thursday, April 21, 2005 - link
We are talking about by this fall, folks. And a 90nm Dual core still uses LESS die than 2 2800+ put together because it is on a manufacturing smaller process, especially if they stick to a 512k cache which is obviously the sweet spot. By this fall I expect that we will see sub $200 dual cores from Intel to squeeze AMD on the desktop market. What is a real shame is that AMD doesn't have suffcient fabs to handle potential demand.For those of you who got all hot in your pants and said I can't buy a sub $200 dual core Intel right now, it is just as true that I can't buy one it all! ;P Chill!

Am I mistaken in thinking that AMD was throwing out their desktop dualcore line (A64 X2) in 2006? What prompted their earlier release of them? Was it the demand for desktop dualcore, pressure from Intel stealing desktop dualcore market, or excellent manufacturing at the AMD plants?KeithDust2000 - Thursday, April 21, 2005 - link
blckgrffn, "so if they can't bring anything out under $200 I will probably have to go with Intel. Boo for that ;) "INTEL doesn´t have one under $200 either.

#14... all socket 939 motherboards will support the X2 with a BIOS upgdate.Zebo - Thursday, April 21, 2005 - link
#9 They'd have to release a 1.6 @ $240 to accurately compete with Intels slowness in Pentium D's starting at $241. Sorry not gonna happen. AMD not for budget shoppers anymore but those interested in performance. Want the best? Pay the price. Or substandard CPU at a discount?I can see a 1.8 for about $250 though however no way you're going to get into DC for less than $200.
