Intel Core i7-975 Extreme Edition Quad Core Processor

The Intel Core i7 is a new line of desktop processors based on the new Nehalem microarchitecture, which evolved from the Core microarchitecture which powered the highly successful Intel Core 2 line of microprocessors. Like its predecessors, the new Core i7 processors is manufactured using Intel's 45 nm fabrication process with high-k (hafnium) dielectric and metal gate technology. However, that is where the similarity ends.

Unlike the Core 2 processors, the new Core i7 processors have a monolithic design. That means the entire quad-core processor is fabricated on a single die. The quad-core version of the Core 2 processor, on the other hand, combines two dual-core dies in a multi-chip package (MCP). The Core i7 processor also introduces a slew of new technologies :

  • an integrated DDR3 memory controller
  • a three-tier cache design
  • QuickPath Interconnect
  • Intel Turbo Mode technology

Today, we will be taking a close look at the new Intel Core i7-975 Extreme Edition processor, which debuted on June 3, 2009. As Extreme Edition moniker hints, this processor comes with unlocked multipliers as well as a correspondingly hefty price tag.

But how fast is it really? After all, this is a high-end enthusiast-grade processor with a very, very hefty price tag. It had better be a couple of Mach numbers faster than the Core 2 processors! Well, this is what we will be looking into this review. Not only will we examine its performance in games, we will also take a look at its performance in 3D rendering and video encoding.

Our Review System

Tech ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a multi-tier review system.

This review system is designed to allow you to quickly receive information on the latest hardware or software. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
