I just wanted to clear up some things regarding K10 MPU(Barcelona,Budapest,Phenom).
First of all,
Barcelona is a K10 server part that fits in both Socket F and SocketF+(split power planes) with only the
BIOS update(info directly from AMD!!).So it's backwards compatible with
ANY socket F motherboard for dual core Opterons currently shipping(RevF stepping).Second ,Barcelona is K10 chip with HyperTransport 1.0 support,not HT3.0.Barcelona is coming in August
with speeds up to 2Ghz,with Tier 1 suppliers having the systems in September.Both standard and HE(low power ,68W) versions will be available.
The HT3.0 K10 chip is codenamed Budapest and will come in late Q3,early Q4 and will be a workstation MPU,for uniprocessor systems( UP).It will fit in
ANY AM2 or AM2+(split power planes) with only a BIOS update!!So it's not a desktop CPU,but will work regardless of that in any
desktop mobo(provided the BIOS is available).
Phenom is Ht3.0 desktop part which comes in November and is basically identical to Budapest and Barcelona(only the Barcelona has HT1.0).Chip has all the features of K10 core arch(improved OoO,32 byte instruction fetch ,L3 cache,improved mem. contrl with prefetch function,L1 direct prefetching,doubled L1 bandwidth,128bit FPU/SSE,SSE4A instruction set,increased number of fast path(direct path) instructions etc.)
Phenom will wit in
ANY AM2 or
AM2+(split power planes) with only a BIOS update needed.
All K10 CPUs have DDR2 integrated mem. controller with support for DDR2 memory(rumor has it that they do support DDR3 also,but still just a rumor).All K10 CPus,when ran in AM2+ mobo can clock independently the mem. controller from the CPU cores.So meme .controller has it's own PLL and can work on higher or lower freq.This will have a large impact on OCing,since the mem. controller has its own voltage plane and can work on less volts and less freq. than the cores themselves.
All K10 CPUs have much better power saving features than K8(and Conroe,Penryn).This will allow K10
to be the most power efficient CPU on the market.
All K10 CPUs will receive a die shrink to 45nm with some arch. improvements in Q3 2008,and will be a competitors to intels Nehalem.All this K10.5(shrank) CPUs will have increased L2&L3 caches,SSE4(full subset) and other improvements to SSE and ALU engines(to help them compete better with nehalem)
I just wanted to post this information since i saw that too many people on this board really don't have correct informations about K10 and motherboard support for it,so i wanted to clear up some things.
I must say that these specs are correct and
not just some speculation.
Hope this info helps clear the confusion around the
mighty K10
