Intel caught using cheap thermal paste in Ivy Bridge?
For all the good stuff it brings, Ivy Bridge has also been running a little hotter than reviewers and overclockers might have liked -- and that's putting it mildly. A few weeks back, Overclockers discovered a possible culprit: regular thermal paste that sits between the CPU die and the outwardly-visible heatspreader plate. By contrast, Intel splashed out on fluxless solder in this position in its Sandy Bridge processors, which is known have much greater thermal conductivity. Now, Japanese site PC Watch has taken the next logical step, by replacing the stock thermal paste in a Core i7-3770K with a pricier aftermarket alternative to see what would happen. Just like that, stock clock temperatures dropped by 18 percent, while overclocked temperatures (4GHz at 1.2V) fell by 23 percent. Better thermals allowed the chip to sustain higher core voltages and core clock speeds and thereby deliver greater performance. It goes to show, you can't cut corners -- even 22nm ones -- without someone noticing, but then Apple could have told you that.
Intel Core i7-3770K CPU review roundup: crossing the Ivy Bridge
Today is officially Ivy Bridge day, in case you didn't already know. Intel took the wraps off the latest member of its processor family and the internet wasted no time putting the flagship Core i7-3770K through its paces. The 3.5GHz quad-core desktop chip comes packing not only some architectural tweaks, but a brand new integrated GPU in the form of the HD 4000. Oh, and it does all this using a brand new 22nm manufacturing process and 3D "Tri-Gate" transistors. What does that mean for you, the user? Lower power consumption, better performance and, surprisingly, unbelievably fast media transcoding. When AnandTech turned its eyes towards Quick Sync, the on-die media transcode engine introduced with Sandy Bridge, the 3770K practically buried the competition. Using Cyberlink Media Espresso the new chip turned a DRM-stripped Blu-ray of Harry Potter (130 minutes of 1080p video) into an iPad friendly format in just seven minutes without taxing the CPU. At idle, power consumption hasn't changed much, but when TechSpot put the pedal to the metal things looked quite a bit different. The new i7-3770K sucked down just 147 watts, which was even four watts less than lower clocked i5-2500K. And, of course, it delivered much better performance. In fact, in Bit-Tech's tests, the only chip that was able to routinely best it was the hexa-core 3960X Extreme Edition -- and even that CPU barely eked out its victories. While AMD's offerings simply can't compete with Intel's on pure performance or power consumption, it does still outrun run Chipzilla's GPU. The HD 4000 is, undeniably, a huge step forward for the Core line, but it falls just short of matching the A8's integrated Radeon on Tech Report's tests.

Intel puts Ivy Bridge on the map: first 22nm product, decent official benchmarks, desktop quad-cores from $174
We hear that pilgrims have already started flocking to the town of Ivybridge (population 12,056) in the forested depths of southwest England. Very soon though, you'll be able to pay homage to Moore's law without travelling further than your favorite online retailer, because the third generation of Intel Core processors has just launched and should be available to buy before the end of this month. These include eight different variants of Core i7 for desktops and notebooks (including Ultrabooks of course), plus five types of Core i5 destined for desktops only. Those watching out for cheaper dual-core i5, i3 and Pentium-branded options will have to wait a little longer, because today's launch is all about the high-end. And just how high is 'high'? Judging from the gossip we've heard, and from benchmarks of leaked desktop and notebook chips, we're looking a significant improvement over Sandy Bridge. But if you want the first official boasts, then read on.
