LGA775 is not dead yet! Also, I'm wondering why the Core i5 680 is released when sources have reported that an unlocked Clarkdale would be coming soon?Intel introduced two new dual-core processors, the high-end Core i5 680, and the value-segment Pentium Dual-Core E5500. The former is an LGA1156 chip that runs on Intel P55, H55, H57, Q55, Q57 chipsets, while the latter is an LGA775 chip that works on most recent LGA775 motherboards. The Core i5 680 uses the 32 nm based Clarkdale core. At 3.60 GHz (27 x 133 MHz) with a Turbo Boost speed of 3.86 GHz, the i5 680 is expected to be the fastest dual-core processor ever made. Its embedded Intel HD Graphics controller is clocked at 733 MHz. It has L2 caches of 256 KB per core, and a shared L3 cache of 4 MB. It supports two channels of DDR3 memory. With HyperThreading enabled, the chip gives the OS four logical CPUs to deal with. It has a TDP of 73W. The Pentium Dual-Core E5500 is based on the 45 nm Wolfdale-2M core, it has a clock speed of 2.80 GHz (14 x 200 MHz), and FSB speed of 800 MHz. It has a shared L2 cache of 2 MB, and TDP of 65W. While the Core i5 680 is priced at US $294, the E5500 goes for $75. All prices are per-piece in 1000 unit tray quantities.
