Intel Removes "Free" Overclocking From Standard Haswell CPUs
crookedvulture writes "With its Sandy Bridge and Ivy Bridge processors, Intel allowed standard Core i5 and i7 CPUs to be overclocked by up to 400MHz using Turbo multipliers. Reaching for higher speeds required pricier K-series chips, but everyone got access to a little "free" clock headroom. Haswell isn't quite so accommodating. Intel has disabled limited multiplier control for non-K CPUs, effectively limiting overclocking to the Core i7-4770K and i5-4670K. Those chips cost $20-30 more than their standard counterparts, and surprisingly, they're missing a few features. The K-series parts lack the support for transactional memory extensions and VT-d device virtualization included with standard Haswell CPUs. PC enthusiasts now have to choose between overclocking and support for certain features even when purchasing premium Intel processors. AMD also has overclocking-friendly K-series parts, but it offers more models at lower prices, and it doesn't remove features available on standard CPUs."
Guh. Premium, not primium! And annecessary = unnecessary. I suck.
It is also significantly slower buck for buck in real life workloads.
Buck for buck? Are you on crack?
AMD wins the price/performance comparison. Intel wins the peak performance comparison.
Looks to me like you are practicing the big lie for your masters at Intel.

Add to the list below rendering and those of us who compress and process video - of which I am one. Faster clock speeds can save me HOURS of time and is why I run an overclocked Sandy i7 at over 4ghz. It runs for hours at a time fully slammed with no problems.
So yeah, there are use cases for this outside of your sphere of knowledge.

In my experiences, they have always outperformed Intel's processors, and generally cost half as much.
That hasn't been the case for several generations of processor design, unfortunately. The top end of the AMD processor line can't compete with Intel on performance. That's why they've gotten so cheap -- so OEMs build systems on them. The 'Intel Tax' puts a lot of their mid-range and above stuff out of reach of the average consumer, and generally you're only finding them in laptops now because of the superior power usage and thermals...
If you want per-unit performance today, you buy Intel. If you want commodity, you buy AMD.
