Athlon X2...with shared L1? here she be folks(taken from AMD website): AMD Athlon 64 X2 Dual-core Details Processor AMD Athlon 64 X2 Dual-core Model 4400+ Ordering P/N (Tray) ADV4400DAA6CD Ordering P/N (PIB) ADA4400CDBOX Operating Mode 32/64 Stepping E6 Frequency 2200Mhz HT Speed 2000 Voltage 1.35-1.40 V Max Temp 71°C Thermal Power 89W L1 Cache 128KB L2 Cache 1MB x2 CMOS Technology 90nm SOI Socket Socket 939 please note the standard X2 listings for the same cpu on AMD website: AMD Athlon 64 X2 Dual-core Details Processor AMD Athlon 64 X2 Dual-core Model 4400+ Ordering P/N (Tray) ADA4400DAA6CD Ordering P/N (PIB) ADA4400CDBOX Operating Mode 32/64 Stepping E6 Frequency 2200Mhz HT Speed 2000 Voltage 1.35-1.40 V Max Temp 65°C Thermal Power 110W L1 Cache 128KB + 128KB L2 Cache 1MB x2 CMOS Technology 90nm SOI Socket Socket 939 Did you spot the difference? ADV4400DAA6CD =128k L1 ADA4400DAA6CD =128k + 128K L1 AMD site compare I'm attempting to get my hands on one right now. more to follow... ![]()

I dunno. Shared L2 cache might make sense. But shared L1? It is quite unlikely in most situations that the two cores are going to be running enough of the same code to make shared L1 worthwhile. At least, it would seem that way to me. |

you got a good point, giz, however i think the missing cache would make for a dualcore tha had lower power requirements, and then might go further in clocking. It gives you almost hte same thing as a hyperthreaded P4, but with one heck of a lot more functionality.

Deal is these aren't in retail yet in force...but they will be. less power requirements but higher max temps....you know what's holding the X2's back from scaling. ![]()

I think it's either a typo (IE, shared L1, shared L2) or a typo (IE, seperate L1, seperate L2). Or AMD moved to harvard architecture, but I think we'd realise that very quickly!

Darn, there I was hoping that AMD had seen the light and decided that they were moving to a Harvard architecture. That would be awesome for speeding up data processing operations!
