K8L , K10 , K10.5 or ... something else ?

But, do you have any proof that Barcelona and Budapest cores are really called so? No. !

K8L is Charlie Demerian scrap "invention". K10 not in 2007, nor 2008? Perhaps dead? Haha.
What he could hear about is only Griffin mobile processor.
K10 is AMD's marketing baloon
K10.5 is an scholar example of FUD.

So what is the truth?. We desperately need it. Well, all of it and nothing of it.

K8L name is correct in indication that it is not true K10 design. Everything else is wrong.
K10 name is correct on its future persepctives, but not on its current architecture state of the art.
K10.5 is actually what K10 is initially intended for. In 45nm technology. But,
AMD is late in technology, behind Intel, and suddenly crippled original design
became christened at AMD marketing as K10.
Alas, that design lacks integrated DDR3 memory controller, SSE4, and due to backward
comaptibility uses for now only 2GHT per second FSB. Why faster FSB without SSE4?. Why
SSE4 support without faster FSB?. Beside, old 65nm technology doesn't allow clock scaling
up too much, at least in 4 Core implementation. And, why it should? 45nm comes in 2H2008. Why to bother?
Lets announce it as low power design architecture and wait for 2H2008.
Revision C in 45nm will encounter all what is missing now.
Thus, K10.5 should be real
K10.
AND WHAT ABOUT CURRENT K10?
My suggestion is that it should be called (the most appropriately): K10_
;)
Beside, do you know any application package that supports SSE4 instruction set now?
But would be at disposal ina year, when 45nm will be ready at AMD. Does it mean AMD will always lack behind Intel in SSE support. Well , no. SSE4 seems is the last SSE sequel.
What will happen after? look at the accelerators boxes below. Definitely, AMD has a future.


Real K10 is a real monster and Intel killer. However,
Intel hopes Nehalem will save its future in 2008/9 .

EDIT: Someone from Russia posted this important link (with love) as a comment.
Oh, by the way, seems that Digitimes confirms my humble reasoning.

AMD intends to modify its process technology to increase the yield rate and frequencies of Phenom processors in order to improve the competitiveness of the CPUs against Intel's Penryn family, said the sources. AMD has already notified several motherboard makers that Phenom will now begin test-production in November or December, and will launch in first quarter of 2008, noted the sources.
