Anything? It is an upcoming CPU from AMD. All discussions from this point on should only discuss this fact and this fact alone. I will start.
Did you guys hear about the Piledriver CPU from AMD? It's coming out in the future.
OK. Your turn.
What's the point of this? Everything that can be discussed has already been discussed.
Piledriver will be faster and a better performer per watt than Bulldozer (as proven by the Trinity reviews), but it's not going to suddenly put AMD on even ground with Intel. In the very best case scenario, AMD might be able to return as a viable budget alternative.
Meanwhile, many of Bulldozer's fatal flaws will remain, and won't be addressed until 2014 at the earliest in the "high end" space (and depending who you ask, never).
There's not much more to say until more information surfaces.
At any rate, Haswell is looking to be far more interesting as far as pure CPU peformance and features go. There's next to no information on what Kaveri is bringing to the table, but it's likely that Vishera will only be appetizing to people that already own an AM3 board. Given how long Vishera will have to weather against Ivy Bridge and Haswell, I only see Vishera being considerably enticing in the scenario that it scaled all the way down to inexpensive dual core parts.
The total energy savings achieved by this technology in integrated circuit chip design dependent and is estimated between 5 and 30%, although the specific case of Piledriver gets reduced to a range between 5 and 10%.
"Cyclos resonant clock mesh technology employs on-chip inductors to create an electric pendulum, or 'tank circuit', formed by the large capacitance of the clock mesh in parallel with the Cyclos inductors," Cyclos explains. "The Cyclos inductors and clock control circuits 'recycle' the clock power instead of dissipating it on every clock cycle like in a clock tree implementation, which results in a reduction in total IC power consumption of up to 10 percent."
Cyclos and AMD didn't go into too much detail about Piledriver, though they did say it will consist of a 4GHz+ x86-64 core built on a 32nm CMOS process.
From what I remember, there were two things that Bulldozer got right: idle power draw - which was lower than the 1100T, and thread scaling - the 2nd integer core adds about 60-80% more parallel performance per module, depending on the app. But there were two things Bulldozer got wrong: lower IPC, and load power draw. I've accepted the fact that Piledriver's IPC improvements will likely not catch up to Sandy/Ivy Bridge, since apparently, lower IPC was by design. But I would like to see clocks increased so that IPS is at a respectable level. And I would like to see the load power consumption lowered. If Vishera/Piledriver can meet these improvements, then AMD will have something worth talking about. Oh, and I wouldn't mind having moar cores. I like playing with moar cores and seeing how many tasks I can parallelize. I'll take an 8M/16C Vishera to play with.

Okay? Do you have anything intelligent to say?"What's the point of this?"
