That is the thing about AM3+ and HEDT, with AMD getting control over the software development in games (indirectly), they don't have to release new hardware to get massive gains out of their existing hardware lineup. Meaning their product line-up will look a lot better simply by changing the software, as opposed to changing hardware.
Even if AMD kept with the same AM3+ and PD Vishera platform until late 2014, with the change in game engine design I wouldn't be surprised if a lot of people who said PD sucked changed their minds.
FX CPUs are not exactly a cash cow for AMD. They could be just putting the platform on hold in the hopes that the new consoles will push Vishera sales, so they end up with more sales without R&D dropped on a new platform.
Bear with me here, there's a lot of ifs, but...
if AMD can get SR to scale like they are claiming (roughly 30% over BD, 20% over PD)
if game engines continue to scale on AMD hardware like the latest BF4 Beta benchmark
if AMD Keeps 300mm^2 die CPUs around the $200 mark
They could completely dominate the gaming PC market when it comes to CPUs.
I do think Intel knows something we don't, they're coming with 6 core and 8 core Enthusiast parts next year. 4930k is only 257mm^2, smaller than Vishera yet Intel is still asking $500+ for it. haswell-e should be around the same size for a 6 core and I see no reason why Intel would change their game of selling 257mm^2 chips for $500+ as the margins must be massive on those chips other than having a good reason from competition.
I've been advocating Intel killing off what they refer to as the mainstream market for gaming PCs for a while, and it's going to happen when Intel doesn't release anything beyond quad core on their mainstream socket and enthusiast starts as hex-core. The next gen of games, if BF4 Beta continues to scale how it has been, will mean going mainstream Intel socket will be a far cry from optimal and will be more of a budget system. It's going to anger a lot of Intel kiddos who are used to buying mainstream parts for cheap.
Anyways, I find it odd that there are 8 core IB chips out there, yet HEDT doesn't get it for Intel. Yet suddenly Intel is going to add two more cores to their enthusiast lineup on the same node? This is more than likely going to force Hex core prices down for Haswell-E while still keeping the die size the same. Which is absolutely what you don't want to do to maximize profits. Intel is reaping ridiculous profits off of 4930k, 2600k was 215mm^2 chip and sold for like $320. 4930k is 257mm^2 and goes for $580.
I don't see why Intel would just throw away their massive profits on such a small die by adding to the die size. Unless you think they're going to make their entire enthusiast lineup start at $580?
But regardless, I am asking the question: "if AMD is going to bail on the HEDT market, why is Intel doing something that would more than likely reduce their profits when they have a really, really profitable thing going on with the status quo?"
IMO Intel knows what we don't and they're scared, so they're going to increase die size, decrease profits, in order to stay competitive.
