![]() ![]() This is the first significantly-improved Intel microarchitecture in quite a few years, as very well explained in this article at Anandtech, and results in a combined 19% IPC increase over Cypress Cove as per Intel’s claims (not compared to Willow Cove -Tiger Lake, though), based on measurements in several workloads and benchmarks such as SPECviewperf, PCMark, WebXPRT or Geekbench. The P-Performance cores are based on Intel’s Golden Cove architecture, a follow-up of the Willow Cove cores in the Tiger Lake processors. Let’s quickly dive into the P and E Cores that form this hybrid design. IPC per-core performance was never a problem for the 11th gen Tiger Lake chips over Ryzen 5000 platforms, but because of the increased power demands, Intel were only able to squeeze in fewer cores than AMD could within a given power envelope on their processors, and thus Tiger Lake Core U CPUs only topped at 4C/8T SKUs, and were trumped as a result in multi-thread performance by the up to 8C/16T AMD SKUs. In theory, this approach would primarily address efficiency, one of the known issues of the recent Intel platforms in comparison to the AMD Ryzen options, while also helping out the overall performance is sustained loads. At the same time, the Little cores are active all the time and either in charge of efficiently running everyday demands, or helping out the Big cores with the taxing chores, based on the requirement. ![]() The Big cores are meant to fire when demanding loads require increased processing power, and rest dormant otherwise. In simple words, Big.Little means that bigger and higher performance cores are paired with smaller and more efficient cores in a single processor. ![]() Unlike with Tiger Lake and previous mobile platforms, Alder Lake is Intel’s first take of a Big.Little platform, an approach common in recent years for smartphones and tablets, as well as something implemented on recent Apple products built on Apple M1/M2 silicon. I’m going to take you through what we know so far, and add in my own thoughts, to help you decide whether you should get an Alder Lake laptop at this point, or rather wait for the next-iteration of Intel 13th-gen Rocket Lake products to be available in stores somewhere next year. ![]()
