piledriver - Official AMD FX4300,FX6300 and FX8350 review thread

We'll have to wait for the Windows benchmarks. If it can maintain or exceed the gaming performance of my PII x4 but with the expected increased multithreading performance I'm sold.

Hurray, logic!

Pretty good price/performance there. Will be interesting to see more reviews.

To be fair, the FX8120 represented unmatched price/performance in some instances.
 
The power consumption figures look interesting, 20W less under load despite higher base and turbo frequency. They must've had some serious leakage issues with the BD transistors.
 
They'd added the energy recycling feature to Piledriver cores:
http://hexus.net/tech/news/cpu/35877-piledriver-surpass-4ghz-barrier-resonant-clock-mesh/

The Resonant Clock Mesh functions by employing a mesh throughout the clock circuitry that, with the aid of Cyclos inductors, interacts with the signal's magnetic field, absorbing wasted energy, storing it in the mesh and subsequently, injecting the energy back into the system. The end result is simple, less wasted energy that would otherwise require dissipating as heat.

Pretty cool technology, it's probably the only major difference between Bulldozer & Piledriver as pointed out in the article:

The technology, developed by Cyclos Semiconductor, enables AMD to either, reduce chip-wide power consumption by 10 per cent, or increase clock-speed by 10 per cent with no impact on TDP, allowing the firm to reach new highs in speed and performance or new lows in power consumption for silicon bound for portables, all without the need of moving to a new manufacturing process.

Yes, hopefully they've included some process refinements too as there was a pretty big difference between the C2 and C3 stepping 45nm chips in terms of power consumption (at least 10%).

So, from what I can see, it's a great CPU for the price....unless you play games a lot.

depends on the games.

games like bf3 that can use multiple cores it competes well with intels.

Games that don't (the majority out atm) it doesn't.

Its better than older AMD's and an improvement in most cases to Phenom II's now.

Brilliant if your rendering and using programs that use multiple threads etc.

If it is going to be £124 like stated then yeh good value to me. Especially if I can sell my phenom 2.
