I also doubt they'll be rolling around laughing, they've just lost their only leading performance area, as it stands AMD are now second with IGP's, regardless of the downfalls of GT3.
The IGP area alone is 165MM2,which is bigger than the chip used in an HD7770 and HD7790,and it needs another 84MM2 of expensive L4 cache to make it viable. The L4 cache is made on a more expensive low power version of the 22NM process. The IGP and eDRAM have more transistors and greater die area than the entire Trinity chip alone. To put it in context the GT650M that Anandtech tested is 123MM2 including additonal logic like the memory controller and uses cheaper GDDR5 RAM and is faster in all metrics.The only thing which looks good compared to the GT650M is the power consumption(the test was at a maximum of 69W TDP though for the CPU),but it comes at the expense of using a metric ton of die area and billions of transistors. If it was not faster than what AMD has it would be an epic fail. Moreover technically AMD still has the lead over everyone else when it comes to IGPs,since the SOCs in the XBox One and PS4 are IGPs and use shared RAM!!
The PS4 actually uses stacked GDDR5 as AMD worked with a company called Amkor. There,was a lot of noise about Kaveri using a similar setup,but ultimately whether it happens is another thing,as cost might be an issue,and due to the weaker CPU performance of the AMD APUs relative to the Core i7 quad cores,they cannot get away with high pricing either.
This is why the GT3e is over $500. It is an expensive,low volume part using brute force. This is why Intel will not price it low.
The lower end SKUs lack eDRAM and so are going to hit the same issues AMD is hitting,as they won't have enough bandwidth,plus Intel is most likely to price them at a premium,looking at past pricing,sadly since they want decent margins.
Ultimately it does not compete with anything AMD has out there in price,so in reality it is the CPUs with HD4600 which are the thing they need to be worried about,which any AMD Richland and Kaveri laptops will be price comparable too.
If anything Intel's need to maintain decent margins due to their high capital investments and their extensive product segmentation in support of this,makes me think AMD is perfectly fine as long as they can compete well with Intel's mainstream low end and midrange offerings,which is bascially where they have been for years anyway with mobile CPUs.
