You don't need a tech blog article to illustrate the obvious. You only have to shop for AMD OEM systems and to know something of the industry's relationship with intel.
In the UK you can get a reasonable number of Carrizo based laptops now.
But the problem is that the article indicates that probably ALL the Carrizo systems are probably gimped with the memory controllers which is not the case,which means the one advantage they have,ie, light gaming is more or less gone.
Even the people who I know wouldn't mind buying an AMD laptop,would probably look at the article and not bother.
The reality is that websites like notebookcheck have shown the memory controllers are fine,even at lower TDPs,as they can be run in dual channel.
So,what the heck somebody is smoking at AMD,I have no clue - firstly sampling bugged laptops which have memory controller problems not seen in production laptops people can buy and then using a Kaveri based laptop running in dual channel to compare to Carizzo systems running in single channel. FFS,how can you have faith in a company which doesn't even seem to realise the laptops in its own HQ are not even fully functional.
AMD has a problem of concentrating too much on the future.
They need to concentrate on the present first so they can actually sell their products,and then that way they can probably stop making the amateurish mistakes they have made with so many of their CPU and GPU launches.
Then its another quarter when they will take a "charge" for inventory write downs.
Even if Bristol Ridge is a decent update and Zen is good,this is the problem with AMD - their marketing just fails massively nowadays and seems very disconnected and disorganised. It lacks coherent focus and misses on important details during launches.
Since AMD is a combined CPU/GPU vendor they need to even more vigilant as any screw-up on both sides affects the AMD brand as a whole. Plus their competitors are ruthless and will make sure any missteps are taken advantage of.
Companies like Nvidia and Intel have released poor products too or hit some big problems too,but in the end their marketing seems to be more in tune with the companies as a whole and have tended to help and not hinder the companies in the long term.
