what spec for intel's 45nm chips in Q3/Q4?

[nyker96]

I'm curious about Intel's upcoming 45nm chips rumored to be in Q3/Q4. few questions:
0. both dual and/or quad on 45nm or just quad?
1. native quad?
2. 775 chips or new pin count
3. they do DDR3/DD2?
4. new architecture or just C2D architecture?
5. what type of FSB speed?
6. supporting chipset?

0. dual (Wolfdale) and quad (Yorkfield).
1. yes native quad with 12MB of shared L2 cache (yorkfield)
2. 775 chips
3. both DDR3 and DDR2 (depending which chipset you will use)
4. Core 2 architecture. Just a 45nm shrink + some new SSE4 instructions
5. both 1066 and 1333
6. New revision of Intel 965 (1066/1333 FSB + DDR2)
New revision of 680i (1066/1333 FSB + DDR2)
Intel Bearlake (1333 FSB + DDR3)

1. From what I understand Yorkfield is actually just two Wolfdales in one package. I know for sure that there are two 6MB L2 caches each one shared by two of the dies. I believe Nehalem will be Intel's first "native" quad core CPU.

hey JAG thanks for reply that 12MB L2 Yorkfield sounds like a real monster chip. but I guess that's shared comes out to like 3MB/core even less than kensfield. All that gonna make things a lot more interesting come Q3/Q4.

less than kentsfield?

kentsfield has 8MB shared between 4 cores, how is 12MB less...

anyways, furen, I may be wrong about yorkfield, i dont remember exactly. it may be a glue job.

I believe that is correct. Intel will continue using the MCM approach to quad core until Nehalem.

thought kens has 4mb/core, my bad.
