I am building a workstation for modeling/animation, and I am not sure whether to wait for the new Istanbul processors or just stick with the current quads. I have done some research, but some questions remain.

1) Does anybody have any take on what the projected cost on an Istanbul CPU will be.

2) Will it support HT v3.1, and if so, will that help to lower the cost per Ghz due to its stock support of higher frequencies than HT 3.0? (i.e. higher stock frequency support = less overclocking = we pay less for higher clocked chips.)

3) If Istanbul is meant to be a drop-in for socket F, does that mean it will support DDR2 and DDR3 memories, unlike the Intel Nehalem architecture?

4) Is it worth dropping into a socket F, or are vendors going to make new chipsets with better support for Istanbul?

Any opinions will be appreciated.

This is what has been said about Istanbul so far:

1. Fits in existing Socket 1207 (Socket F)
2. Motherboard requires split plane (dual dynamic power management)
3. Should be about 30%+ faster than shanghai

It really boils down to how threaded your app is. If it is very threaded, it should do great in Istanbul. If your app is less threaded, then you may have better performance with shanghai because it will have higher clock speed.

Why would the number of threads matter if Istanbul is not multithreaded, and likewise, how would a higher clock speed be benificial for less threaded apps if Istanbul has more cores and may support a higher bandwidth?

well people I went for Dual Shanghai 2380's these are great for converting Avi to HD DivX,as playing games like Crysis and simulators like Flight Simulator X Deluxe Edition in all highest settings possible, FSX loves Opterons hehe

So here it is, a Dual Opty 2380 up and runn'n lads

Here's my results with Cinebench 10 @ 1x 2500 Mhz & 8x 2500Mhz.

Oke here it is will the Dual ASUS Triton 70 coolers mounted

That are these

Here's a vid of this Dual Shanghai 2380 C2 in action

Anyways what will the Instanbuls carry L1 / 2 / 3 cache wise?

6x 64KB L1 Data
6x 64KB L1 Instruction
6x 512KB L2
1x 6MB L3

Or

6x 64KB L1 Data
6x 64KB L1 Instruction
6x 1MB L2
1x 6MB L3

As for model numbers would the Istanbul CPU's be the Opteron 2400 series? if so could be 4th Generation Opterons, heh Opteron 2200 series were the Santa Rosa's the 2200 series as in 2 way CPU's 2nd Generation Opterons and 00 for model number

2300 series 2-way CPU's , 3rd generation Opterons and 00 for model number

so 2400 series could be like so:
2-way CPU's, 4th Genration opterons and 00 for the model number right?

same idea for 8200 / 8300 as 8400 series, just a deep thought there
