AGENA and KUMA details...

[hmammen]

Dont know if this has been posted yet-


Core Enchancements:

128 Bit floating point:

• Applies only to Agena & Kuma

New SSE4A instructions:

• Advanced Bit manipulation
• MWAIT & MONITOR instructions
• Misaligned SSE Mode

Additional Features:

• Power management state invariant time stamp counter (TSC)
• increased number of TLB Page entries
• 1GB large paging support
• Physical address space increased to 48 bits

IMC Enhancements

DDR2 Dimms in products variations:

• Socket AM2+: Dual Channel unbuffered 1066 support
• Socket 1207+ Dual Channel unbuffered 1066 support

Memory Controller enhancements

• Write Burst & DRAM prefetching performance improovements
• DRAM writes can be buffered in the memory controller before being opportunistically bursted into DRAM controler to improve DRAM interface efficiency
• Read prefetcher detects stride paterns and issues prefetch requests based on confidence level
• Channel Interleaving

Roadmap:

Agena FX:

Q3 2007:
2.7-2.9GHz
2MB L2 total L2 cache for the CPU (quad core so 512KB each core)
2MB shared L3

Mmmmm... AMD goodness.

Time to go back to AMD.

 

[hmammen]

This is the main reason I havent gone over to C2D....im waiting for these beasts.....i wonder how the 2mb cache will compare to my 1 md cache with my opty....maybe it will be a noticable difference.

 

[Nagasama]

pardon me, did you say...
4000 MHz hypertransport bus....?
woot ****** woot!!

 

[Phantom118]

I might go the amd route for once....

 

[hmammen]

pardon me, did you say...
4000 MHz hypertransport bus....?
woot ****** woot!!

exactly what i was thinking....

 

[darksideleader]

wow hope these CPUS will be at good prices, is AM2+ a whole different socket?

 

[b1gapl]

Nope...they will be compatible with socket AM2.

 

[hmammen]

It says it will be compatible with socket am2 and 1207, well what is socket 1207 then??
