AMD's Phenom II X4 TWKR: We Give It The LN2 Treatment
Two AMD Phenom II X4 42 Black Edition TWKR (whew, that's a mouthful) CPUs, side by side. This is a picture that you'll likely not see anywhere else. After all, these are pretty rare chips. The TWKR-edition CPUs are currently the most sought-after and coveted AMD processors in the world, at least if you're a hardcore overclocker. Ever since pictures of the TWKR CPUs were leaked a few weeks back, enthusiasts everywhere have been buzzing about them. What hidden superpower do these chips have? What makes these processors so special? Tom's Hardware, along with Team IRONMODS, will put these two chips to the test to see what really makes them tick. But first, here's a bit of background on these unique offerings.
According to AMD, there are approximately 100 TWKR processors in the world. These chips were created especially for the extreme overclocking community to operate beyond the specification of typical production-level processors. What makes these chips special is the fact that they are considered “high leakage” parts. In this context, high leakage means that the processors "leak" more current than a normal Phenom II CPU and consequently run hotter, which actually turns out to be a positive for the overclocking crowd (even if it means they're more likely to die an early death). They can take on more voltage and generally tend to scale higher when cooled with extreme methods, such as liquid nitrogen or liquid helium.
