Intel has finally announced the launch of Nehalem microarchitecture into mainstream PCs with the release of its first Core i5 chip a couple of days back.
The Core i5-750 is the first chip based on the Nehalem design. It runs at 2.66GHz and has 8MB of cache. It consumes 95 watts of power. It comes with a memory controller onto the chip that provides a faster access path to memory. Further, this Nehalem offers a faster pipe for the CPU to communicate with system components.
The new Intel Core i5 processor series, two new Intel Core i7 processors introduced last November and the Intel Xeon processor 3400 series are all based on this new Nehalem technology. They also support Intel Exclusive Turbo Boost Technology. They deliver high performance and are faster and more power-efficient.
The Core i7 processors also support Intel Hyper-Threading Technology. The new Core i7 and i5 processors are among the first Intel processors that integrate both a 16-lane PCI Express 2 graphics port and two-channel memory controller, so that all input/output functions can be handled easily by the single-chip Intel P55 Express Chipset. Interestingly, this new line of processors supports new Land Grid Array (LGA) 1156 package and socket technology.
Intel has also released the Uber Gamer Championship along with Zapak to mark the launch of the new Core i5 and i7 processors. The newly launched, the Core i7-870 processor runs at 2.93GHz, while the Core i7-860, which runs at 2.8GHz. Both of the processors have 8MB caches.
