What are you talking about? The FX series is known to run hot, even above tdp at stock clocks like theres minimal binning going on, probably because the company is sliding under the waves. And because of that, theres the problem of motherboard throttling at stock settings because vrm's are stressed out.
Its the other way around with Intel. Very conservative and no problems with heat that they even had the cheek to substitute paste for solder underneath the heatspreader.
No problems with heat? There are some who complain that their Haswells aren't stable running Prime95 28.5 at stock. While hardly scandalous, it isn't entirely accurate to say that Intel chips are always running cooler thanks to their lower TDPs.
FX operates at lower temperatures than Intel CPUs, you clearly have this the other way around. And TDP is not power or energy consumption.
Also the VRM throttling on some motherboards is not the FX fault but the Motherboards design.
They controlling the VRMs through temperature, other motherboards give you the choice to control the VRMs through Current(I).
What you are saying sort of plays into one of my previous comments in this thread (and serves to highlight why FX price cuts alone may not be enough).
From an enthusiast's point-of-view, the only reason to get an FX is to overclock it to 9590 levels of performance so as to mitigate Piledriver's single-threaded performance problems. So, that means getting an 8320 or 8350 (or 8320SE/8370SE after Sept. 1) and pushing it to 4.5-4.7 ghz at least, depending on what is allowed by the silicon lottery.
Now you have to deal with the fact that only a few motherboards out there reliably support the kind of power draw that Vishera can muster at such speeds. Assuming your overclocked chip is pulling over 200W (which is not outside the realm of possibility), you do not want to be caught with a 4+1 phase board, period.
If you are going to stop at the 4.5-4.7 ghz range, the Gigabyte UD3 is probably the sweet spot with a 6+2 phase design. There are reportedly some folks that have run the 9590 (often with a bit of undervolting) on this board.
If you want your FX to shine in all its glory by shooting for 5 ghz or higher, then it's pretty much the Sabertooth. There are other options, but most of the good ones cost more.
So, just looking at the board, you can expect to pay at least ~$110 for the UD3, or $170 (or more) for the Sabertooth. And that doesn't even include cooling for the chip, which will almost certainly have to be a strong aftermarket HSF or better. Some of us are fortunate enough to already have big HSFs sitting around, but even those might not be enough for the 5 ghz club.
And since neither the UD3 nor Sabertooth have onboard video, you're going to need a vid card too.
Alternatively, if you are just looking for WCG points, you could probably get a cheap 4+1 board and run an 8320 undervolted (or maybe one of the new 8370SEs) for much, much less money.
But, I digress.
For those of us determined to make the most of the FX in a wide variety of tasks, overclocking is a must, and when overclocking comes into play, the need for excellent cooling and solid boards rears its ugly head.
I realize that Kaveri does not offer the kind of multithreaded power of an overclocked FX, but for my money, I would much rather see an A8-7600 on an Asus A88x Plus. Allegedly, the Asus Plus and Pro boards can be made stable at 129 mhz blck in IDE mode, allowing for the 7600 to hit 4257 mhz. You probably wouldn't need much of an HSF to pull that off, either, AND you wouldn't even need dGPU unless you really wanted one.
And all that for maybe $200-$220 for CPU + board.
FX ownership is expensive even before taking utility bills into account.
If board costs can come down somehow, then the prospect of AM3+ being a discount overclocking platform might seem more realistic. As it stands, there are too many other interesting budget overclock options going on right now (G3258, maybe the A8-7600, the 860k) for octal-core FX to fit in, even with a healthy price cut.
