Intel has launched the Xeon 7300 platform codenamed "Caneland" and the Core micro-architecture Xeon MP Processor codenamed "Tigerton". Since AMD is set to launch "Barcelona" quad-core Opterons next week and DailyTech leaked the Barcelona price list, we can now compare the prices for the new MP (multi-processor platform) CPUs.
*Note that all the unit prices listed below are for quantities of 1000 ** IBM X3950 M2 X4 chipset (DDR2-based) *** Unisys 32-socket chipset
|Intel Tigerton XEON MP price list (4, 8-16**, 32*** socket)|
|X7350 quad-core 8MB cache||2.93 GHz||130W||$2301|
|L7345 quad-core 8MB cache||1.86 GHz||50W||$2301|
|E7340 quad-core 8MB cache||2.4 GHz||80W||$1980|
|E7330 quad-core 6MB cache||2.4 GHz||80W||$1391|
|E7320 quad-core 4MB cache||2.13 GHz||80W||$1177|
|E7220 dual-core 8MB cache||2.93 GHz||80W||$1177|
|E7310 quad-core 4MB cache||1.6 GHz||80W||$856|
|E7210 dual-core 8MB cache||2.4 GHz||80W||$856|
|AMD Barcelona Opteron quad-core price list (4 and 8 socket)|
|8347 HE||1.9 GHz||68W||$861|
|8346 HE||1.8 GHz||68W||$688|
[update 5:07PM - I should clarify this "win" I'm granting AMD on energy efficiency against is at the low-end. When you get to Intel's 80W E7340 2.4 GHz 8MB Cache model, you get a lot more work done which offsets the small power differential which changes the performance/watt metric significantly. [UPDATE 9/8/2007 -
Furthermore, Sun's engineer explained that the Barcelona processors only support 4 DDR2-667 memory DIMMs because that's a limit of DDR2 technology UNLESS you're willing to drop down to DDR2-533 memory which Sun is not willing to do. This is why Sun's next 4-socket Intel server will have double the memory capacity of Sun's 4-socket AMD server so it isn't a black and white argument on DDR2 versus FBDIMM. This information I got isn't correct. Each Opteron chip has two channels which means any 4-socket Opteron server will natively support 32 DDR2-533 or 667 DIMMs. I could have sworn 2-socket servers had 16 DIMM slots which they do so I thought the info I got from the Sun engineer sounded funny at the time but I figured he would know better.] IBM went to a very expensive and exotic design with their X4 chipset to be able to utilize DDR2 at high capacities.
We also need to recognize the fact that the 4-socket market cares about performance and memory capacity first and foremost. Customers of 4-socket servers are willing to pay 4x the money for 2x the performance. Someone willing to pay a $10K to $20K premium up-front for just a little more performance isn't that worried about saving $100-$200 on power per year.]
We will not know exact performance numbers for Barcelona Opteron quad-core until hopefully next week. Of course when they do release performance numbers, I'll do a detailed price, watt, and performance shootout. AMD by all estimates will dominate memory-intensive HPC (High Performance Computing) but they will not likely threaten anything above the Intel E7320 on mainstream server performance until AMD can ramp the clock frequencies on Barcelona.
