Exactly Why Is The Intel Core I7 Processor So Much In Demand

You probably seen new computer systems from Dell, Gateway and others using a brand new, bizarre-sounding chip from Intel: the Core i7 processor. You may have also noticed some benchmarks and features showing that this is a real beast of processor. Okay, we're really excited about the Core i7 processor, so here's an easy guide to why it's so amazing:

Fine, so the way Intel develops chips is on what it calls the "tick-tock cycle". The "tick" is the improvement of its present micro-architecture, typically shrinking it down to make it more power efficient, with the other tweaks. As you now may guess, the "tock" indicates the launch of a completely new micro-architecture.

Penryn, for instance, was the tick to the Core 2's tock, minimizing it down from a 65-nanometer process to 45nm. Core i7 is a tock, making use of a completely new micro-architecture codenamed Nehalem. Core i7 Nehalem is certainly an impressive step ahead, remedying several lingering Intel architecture inadequacies that AMD actually had them outrank on years back. So, here are 4 factors that particularly make the new chip awesome:

Bye Bye Front-Side Bus

The early front-side bus setup has always been a lug on Intel's chips, and they're finally ditching it. The FSB generally transported computer data between the CPU and memory controller hub, but that didn't work so well when you started discussing buckets of cores. Rather is a new technology known as QuickPath Interconnect that'll make the older bottlenecks history and running a lot of cores even better.

QPI uses immediate point-to-point contacts that have a bandwidth of roughly 25GB/s, way quicker compared to what FSB could offer. The drawback is that it requires a brand new QPI-friendly motherboard. This idea is kind of cribbed from AMD, whose Hyper-Transport continues to be doing something alike for years.

Integrated Memory Controller and Triple-Channel Memory

Before, with Intel chips, communication had to take place across the front-side bus, making stuff slow. The last memory bonus is Core i7 sustains triple-channel memory.

Right now, you're possibly on a computer with dual-channel memory (in English, I denote that it uses RAM sticks in sets of two). Core i7 will make three sticks of RAM the new standard-so keep an eye out for a good amount of 6GB and 12GB systems operating around.

The Return of Hyper-Threading

Intel abandoned Hyper-Threading after the Pentium 4, however it's back into Core i7 (and Atom, but actually, psh). Basically, it's a parallel-processing tech that runs multiple threads at the same time. In English, it divvies up jobs so they can be crunched by a processor at the same time, rather than one after the other. It short, it helps make video encoding and other parallel-friendly processes operate faster.

We're planning to see what type of gains this will generate in conjunction with applications coded to take advantage of threading, not to mention the next great operating systems, Snow Leopard and Windows 7, which will apparently make better use of numerous cores and parallel processing than current OSes. The i7 2600K Processor is just one which will surprise you.

So yeah, this i7 processor review gets our engines running, and we're not even chip nerds. (Frank!) Sadly though, now there are simply a few Core i7 chips accessible, and they're all for desktop computers. There's little of a downside for portables-save for the need for new motherboards and the DDR3 RAM already used by premium laptops-but before you observe it in a Dell XPS notebook or MacBook Pro, you're going to notice it in lots of desktop gaming and graphics-intensive systems. Laptops possibly won't emerge until way into up coming year, but we think they'll be well worth the wait.
