CMT = paperOriginally Posted by Mechromancer
CMT = paper
AMD didn't choose multi-threading like Intel did for their Pentium 4 in the Athlon 64 and their realized that it is a mistake. So they won't do this again!!!
Main Rig:
Processor & Motherboard:AMD Ryzen5 1400 ' Gigabyte B450M-DS3H
Random Access Memory Module:Adata XPG DDR4 3000 MHz 2x8GB
Graphic Card:XFX RX 580 4GB
Power Supply Unit:FSP AURUM 92+ Series PT-650M
Storage Unit:Crucial MX 500 240GB SATA III SSD
Processor Heatsink Fan:AMD Wraith Spire RGB
Chasis:Thermaltake Level 10GTS Black
I don't think that's accurate. Since CMT isn't something they're likely to just tack on at the end and AMD is likely to be experimenting with pieces on silicon at this point, I think it's rather more likely that it isn't just some neat concept paper. At the very least, its physical implementation has probably been designed.
Particle's First Rule of Online Technical Discussion:
As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.
Rule 1A:
Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.
Rule 2:
When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.
Rule 2A:
When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.
Rule 3:
When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.
Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!
Random Tip o' the Whatever
You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.
Particle is correct since Mr Bergman stated in the Q&A session of the Analyst day that they are twiddling around with the first samples at this moment in time and that they will be shipping the product to their partners (for evaluation and testing purposes ) in first half of 2010,just by the time the whole range of Magny Cours and Lisbon product is launched.
Didn't AMD say SMT was nothing for them and they focused on CMP?
At that time of spoke, there were less than 0.1% of software supporting this and VMwares are only used on servers
Now, VMwares are entering desktop level and more and more softwares are taking the advantage of multi-core and multi-threading.
Things change and so do trend, Intel once thought their CPU would reach 10GHz in a few years. Aren't they were right at that time of speaking??
Do not just take a paragraph out of context

i would not make any claims about performance based only on patents even though i am still excited about bulldozer. sure they probably changed the architecture (more specifically out of order engine) for CMT but only AMD knows how effective it is. its a little annoying to see the blogs and threads on bulldozer discredit intel's architectures. they either do it wrong or amd does it better.
prescott needed SMT badly. now with more multithreaded apps and >4 cores it provides a benefit to all cpu's.
