Reviewers Didn't Like

  • Limited GPU performance
  • No dedicated GPU memory
  • Still only 16 PCIE lanes
  • Early production stepping doesn't overclock as well as current Sandy Bridge
  • Not a huge step up from Sandy Bridge, Average overclocking potential on air
  • Offers only minor performance improvements on highest-end last-generation CPU, Graphics still not comparable to what you get with a discrete video card

Although I didn't spend much time playing Batman: Arkham Origins, I remember the game rather well after testing it on no less than 30 graphics cards and 20 CPUs. Arkham Origins appeared to take full advantage of Unreal Engine 3, it ran smoothly on...

When put to the test we see that the Ivy Bridge architecture isn’t greatly different to Sandy Bridge, but we were expecting that. Many of our real-world application tests such as Excel 2010, WinRAR, and Photoshop CS5 saw very little difference in perf...

The advantage of Hyper-Threading makes the Intel Core i7-3770K the most powerful processor of the Ivy Bridge series. With its larger cache and Hyper-Threading, it was able to win this comparison against its smaller brother. It also ran cooler than our...

If you’ve been looking at building a new PC lately, then chances are you’ve heard of Intel’s latest range of CPUs, codenamed Ivy Bridge. The Core i7-3770K is one of the first products in that range, and this month we had the opportunity to take one...

The Ivy Bridge Core i7-3770K doesn't make a giant leap ahead of the previous generation of Core i7 chippery. It’s more of gentle step forward. But the die shrink down to 22nm does make for a far more power efficient chip than the previous generation...

Intel has confirmed its status as leader in the market for desktop computer CPUs with a new generation of processors that are faster and less power-hungry than their predecessors. Although the gain in performance isn't enormous, it's certainly still...

The 3rd generation Core CPU is a step up from the 2nd generation Core and builds on the success of its predecessor. Through new technology and a smaller manufacturing process, it provides faster performance, a marked improvement in integrated graphics...

When it comes to productivity, it’s clear that Intel’s processors are the best choice. While some argue it’s not the best bang for buck, just consider the performance-upgrade time frame. Users who have purchased one of the the last two Intel...

If you already own a Sandy Bridge PC then it makes little sense to upgrade your existing processor but if you're buying or a building a new PC we have no doubt that Ivy Bridge is the only game in town. Pros: Superb power efficiency, excellent...

The launch of Ivy Bridge has hardly been discrete. Intel has had arguably had one of its most disorganised product unveilings ever, with dozens of reviewers leaking information early, overclockers posting benchmark scores and Intel themselves changing...

Interestingly, Intel's own literature suggests the biggest beneficiaries of its 22nm process node will be server and smartphone processors. What Intel is saying is that its 22nm processors will bring lower power consumption and enable it to finally...
