Dan, You responded by posting scores from IBM's proprietary 64mb L3 box.
That´s why I said you don´t know what you´re talking about. The main feat of X3 is the significant cost reduction IBM has achieved over older platforms, while still offering a very high level of performance. There is no 64MB L4 chipset cache anymore (it was designed out), not even L3 on the Xeons because it performs best with the cheap version of Xeon without any L3 cache (that costs less than 1K even in the fastest version, significantly cheaper than the 852 Opterons). I called it a sea change for 4-way INTEL platforms because it´s hitting very comparable price points to current 4-way Opteron systems, while outperforming it on many high-profile server apps.
Your claim You can buy 3 of the HP Opteron 4-ways for the price of 1 IBM 4-way. is simply wrong.
You've got to pick one or the other to hold a meaningful discussion. Either similar systems with similar costs, in which case Opteron beats Xeon, or stacking up a very expensive OEM cache added proprietary platform, in which case Opteron dual core boxes will still win, while still costing a lot less.
Dan, I said Xeon DP 2M @ 3.6Ghz is very performance competitive with Opteron 252. That´s the discussion we were having. Pete brought up all sorts of nonsense, posted wrong scores, made numbers up etc. just to avoid admitting that it is indeed not just competitive, but even faster in many (important) cases. I was just pointing that out. But this is the discussion I brought up:

Perhaps you look up what Xeon DP 3.6Ghz 2M scores on SPECint_rate, since you brought it up. You will find that even there, Xeon has caught up.
And make sure you update your cost picture. X3/Xeon will be the
biggest competitor for 4P Opteron going forward, especially once INTEL´s DC is out. It´s an amazing piece of work, I wished they´d adapt it to Opteron. |
