Intel Core 2 Extreme QX6850 review
26 June 2008
Conclusion: However, there are still a few concerns I have with an Intel quad-core "Kentsfield" processor clocked at 3.0GHz, which I did not get a chance to fully investigate over the weekend. First of all the Core 2 Extreme QX6850 does have a thermal design rating of 130 watt, just like the QX6700. However while benchmarking this new quad-core processor we noticed that it ran extremely hot at all times.
Excerpt: What goes faster than a Core 2 Quad processor at 3GHz? Unfortunately, or fortunately depending on your perspective, nothing from AMD at the moment. Thankfully Intel has a few more "MHz in the can", or so to speak. Actually, it appears they may have a lot more, as you'll see in the pages that follow. Let's not get too far ahead of ourselves though. First, Intel had to lay the platform foundation to support higher performance.
Pros: More system bandwidth, Better multithreading performance, New lower power die stepping, Fantastic overclocking, The fastest processor we've tested to date.
Summary: So, we've seen an awful lot of interesting performance data, but it all boils down to this: the Core 2 Extreme QX6850 doesn't change much. The QX6800 was the fastest desktop processor before it, and the QX6850 brings slightly higher performance in the same power envelope. The faster 1333MHz bus doesn't pay huge dividends, even for this quad-core part, but we did see reasonable gains in certain memory-bandwidth-limited tests.
Would I recommend buying this product?
Conclusion: With its quad processing cores running at 3.0GHz, the Core 2 Extreme QX6850 is the fastest processor we’ve tested. In general the 1333MHz FSB in particular buys the QX6850 an additional 3-5% in performance in games. As we mentioned in the E6750 article, this may not sound like a lot at first, but actually this is roughly the equivalent of a 200MHz speed boost in clock speed. That’s a pretty nice improvement in our opinion.
Excerpt: Just a couple of weeks ago I first reviewed and tested the new 1333 MHz front-side bus Intel Core 2 processors; it was in the form of the Core 2 Duo E6750 CPU . When that review was posted Intel had not yet officially unveiled or announced the part but instead they allowed us to give a brief overview of performance on a somewhat slower part.
Intel Core 2 Extreme QX6850 and Massive Price Cuts
16 July 2007
Conclusion: Despite theoretical showings on paper, the 1333MHz FSB appears to do very little for performance even when feeding four of Intel's fastest cores. The Core 2 Extreme QX6850's performance is nothing to scoff at, but given its price tag we'd strongly recommend one of the cheaper quad-core offerings. With the Q6600 coming in at $266, it's tough to resist.
Excerpt: To boil it down, this processor will blow you mind if you ever personally witness it ripping through data and information like an F5 tornado through a Oklahoma trailer park. It is equally as awe-inspiring and you might just lose your house paying for it.
Conclusion: Earlier this month, AMD had finally made announcements on the projected retail availability of its next generation native quad-core processors and as far as AMD officials are concerned, they expect revenue shipping parts by end of August 2007 while AMD platform partners are expected to ship their solutions in September 2007. These are still projections, but the time is definitely drawing near AMD's much awaited processor refresh.
