The Penryn microarchitecture, a shrink of the former, introduced SSE4.1. With a maximum thermal design power (TDP) of 65 W, the Core 2 Duo Conroe dissipates half the power of the less capable contemporary Pentium D-branded desktop chips that have a max TDP of 130 W.
The Penryn microarchitecture, which is an improved version of its predecessor, includes SSE4.1. With a maximum thermal design power (TDP) of 65 W, the Core 2 Duo Conroe dissipates half as much energy as less capable contemporary Pentium D-branded desktop chips with a max TDP of 130 W.
