In order to perform at such high
levels without sucking up massive amounts of energy, IBM has designed a way to improve the energy
efficiency and cooling requirements of the 1,024 quad -
core Intel Xeon processors.
CPU performance is especially good from the 64 - bit octa -
core array, and although the GPU is slightly weaker in Samsung's SoC, better
efficiency and lower
levels of throttling see it win overall.
