[citation][nom]stm1185[/nom]I am doubtful about that since its not that huge of a departure from Bulldozer. I wish they'd scrap the architecture and work up a new CPU based around performance per core not packing as many cores as possible. Which with the increasing use of GPU power and their APU line would have made a lot more since for them to begin with.They need to do what Intel did after the Netburst failure, and come up with their own Core![/citation]
Bulldozer actually isn't a bad architecture. Most of it's problems aren't the CPU's architecture, but poor design methods and poor cache. Sure, the Bulldozer architecture needs a little work, but most of the work needs to be done on how the CPUs were designed. For example, one of the top engineers from Bulldozer said that the CPU's were completely computer designed. This is a problem because purely computer generated designes are known to be inferior to hand-made designs. Some performance critical parts of the CPU have always been hand-designed, but FX was not. Supposedly, this decreased performance by about 20% whilst increasing size and power usage by about 20%.
Fixing that and the cache alone (way to high latency) could result in a a large power usage reduction and an even larger performance increase, making it rival Nehalem in IPC, but being a little more power efficient. FX is also capable of remarkably high clock rates and with these improvements, it should be able to go pretty far up. It seems to scale power usage with increased clock rates a lot better than Sandy Bridge (but starts off with more power usage so the scaling isn't enough to catch SB in efficiency) so it could have very high clock rates, helping to counteract it's still slightly inferior IPC.
The best part of this is that it shouldn't be too hard to fix these problems in comparison with making a new architecture. AMD doesn't even need to do a die shrink yet, they just need to fix the major problems first. The question that remains to be asked is whether or not Piledriver has such enhancements, or if it is a more architectural improvement. Either way, it has a lot of potential, but what remains to be seen is if AMD manages to do it or not. I hope so, but I find it hard to have much faith given the current situation of the company. The last time they had a decent CPU architecture come out was the start of Phenom II, but since Sandy Bridge came out, there has been little to say for going with AMD. With Ivy right around the corner, AMD may need to really drop the ball on Intel with Piledriver to make a dent in the market.
