AMD Unveils Carrizo APU With Excavator Core Architecture
MojoKid writes: AMD just unveiled new details about their upcoming Carrizo APU architecture. The company is claiming the processor, which is still built on Global Foundries' 28nm 28SHP node like its predecessor, will nonetheless deliver big advances in both performance and efficiency. When it was first announced, AMD detailed support for next generation Radeon Graphics (DX12, Mantle, and Dual Graphics support), H.265 decoding, full HSA 1.0 support, and ARM Trustzone compatibility. But perhaps one of the biggest advantages of Carrizo is the fact that the APU and Southbridge are now incorporated into the same die; not just two separates dies built into and MCM package.
This not only improves performance, but also allows the Southbridge to take advantage of the 28SHP process rather than older, more power-hungry 45nm or 65nm process nodes. In addition, the Excavator cores used in Carrizo have switched from a High Performance Library (HPL) to a High Density Library (HDL) design. This allows for a reduction in the die area taken up by the processing cores (23 percent, according to AMD). This allows Carrizo to pack in 29 percent more transistors (3.1 billion versus 2.3 billion in Kaveri) in a die size that is only marginally larger (250mm2 for Carrizo versus 245mm2 for Kaveri). When all is said and done, AMD is claiming a 5 percent IPC boost for Carrizo and a 40 percent overall reduction in power usage.

workin on the Linux drivers .. or atleast letting someone else work on them ..
I'm afraid you have been SCAMMED, as Intel has been bribing the benchmark software companies to rig their tests. there is currently a major investigation in the EU over this and it looks like Intel may get even more in fines than they had to shell out to AMD over their OEM bribery scandal. The latest one caught was Cinebench, if their software detected an AMD APU/APU it would drop ALL SSE optimizations and run ALL the math in X87 mode, a mode that has been depreciated since the P3. yes they were rigging THAT badly.
If you take the rigged benchmarks out of the equation? Then surprise surprise AMD chips trade blows with chips costing more than twice as much with several tests the AMD outright smoking and in others within a couple percentage points of the i5s. Again we are talking about $120-$150 chips against $300+ chips and when you figure up how much more powerful your hardware could be if you put that extra $150 into the GPU or more RAM? Its really easy to choose AMD over Intel in the sub $700 mainstream price point. Oh and the AMD wrecks your power bill bullshit is just that, with 17 years required to make Intel come out ahead on power savings versus the increased cost.
So DO NOT BUY THE LIES, Intel has been caught over and over AND OVER committing bribery and outright market rigging to insure they can get the press and benches to say what they want it to. The fact that they have risked so many fines and sunk so many hundreds of millions on bribes should make you ask yourself one simple question.....if they were REALLY so far ahead, why risk it? Why not simply stand on their merits and let the chips fall where they may? Maybe because they are NOT as far ahead as the rigged benches they paid for indicate and they are afraid of losing their jacked up premium if they have to compete in a fair market?
ACs don't waste your time replying, your posts are never seen by me.
Do you have a link for that? It's not that I disbelieve you, I strongly suspect that Intel would do that crap. I'd like to read more about it however if you hae a link handy, then stash the link for the next time this benchmark comes up.
Personally, I like the Phoronix Linux benchmarks. They're more meaningful for me since I use Linux and they're all based on GCC which is trustworthy.

The i7 4770 ocasionally blows away the FX8350 by a factor of 2, but in many benchmarks they're close, and Intel loses a fair fraction. The 4770 is the best overall performer, but not by all that much. It seems that the choice of CPU is fairly workload dependent.
For servers, I still prefer the supermicro 4s opteron boxes. 64 cores, 512G RAM, 1U. Nice.

The best evidence I know of is this one:

You can see how changing the ID string of the CPU will change the performance of the exact same hardware.
