Beg your pardon' it would nice if you knew what you are talking about . The piledriver is 15% faster on IPC than bulldozer. That is Not chump change. Wait until actual official benchmarks are run after release date. The OBR benches are fraudulent and he has a track history of deception as a shill for Intel. I fully expect this chip to give the I7 2600k a run for the money definitely wiping it out for multithreaded apps like Photoshop and holding its own for gaming apps.
Call me ignorant all you like. Do you know what changes they made to the core? I would suggest you look it up. If you think piledriver is going to have 15% more ipc then i'm sorry just not going to happen. Amd Promised 10-15% more performance. Its like 5% better IPC the other 10% coming from clock speed.
There are actually a few benchmarks floating around other than OBR now.
Pile-Driver is a tweaked Bulldozer core, the only differences are TLB overflow, some better branch prediction, and lastly clock resonant mesh which reduces power requirements by 10% or 10% more clock speed for the same TDP. Hate to bust your bubble.
If you looking for big improvements Pile Driver is not the answer, you have to look at the next Generation of Bulldozer core, aka Steam Roller, before they will get alot faster. Due to AMD going in and fixing major architectural bottlenecks. One of those is the decoder, currently 2 integer cores and 1 fpu share a decoder. This bottle neck is addressed, and combined with a node shrink 28nm. Steam Roller might actually flatten Intel, might being the key word as it will be positioned against Intel Haswell.
