Physics, Ivy Bridge, and the slow death of overclocking
"Focusing on the chip’s thermal paste obscures the larger trends. With bus-based overclocking having largely gone the way of the dodo and AMD unable to offer an enthusiast challenge to Intel, the days of buying a low-end chip and ramping the clock 30-50% to compensate are well and truly gone."
"Will Haswell change things? It’s not impossible, but it’s also not where Intel’s energy is focused. All of Intel’s manufacturing prowess is turned towards building smaller chips that draw less power, not ultra-high-performing chips that sacrifice efficiency to hit skyrocketing performance targets."
