KabyLakeDie

Last calendar week, nosotros reviewed Intel'due south Core i7-7700K and discussed the details on the Kaby Lake refresh bicycle, including Intel's new Cadre i3, i5, and i7 processors. Intel, yet, appears to accept had one more fox up its sleeve. The CPU giant appear multiple new Pentium-class CPUs based on Kaby Lake, including the first Pentium SKUs to feature Hyper-Threading since Intel retired the Pentium iv.

E'er since Intel transitioned to its Core compages in 2006, the Pentium brand has been used for lower-stop processors with lower clock speeds and fewer features. Hyper-Threading wasn't initially a differentiating factor because the Core and Core 2 families didn't apply it. By 2022 Intel had introduced Westmere-derived Pentium processors and (mostly) used the following formula for its desktop processors (those wanting a more detailed breakdown on Intel's SKUs should consult our buying guide for the Core i5/i7 families):

  • Core i7: Four (or more) cores. All CPUs take Hyper-Threading
  • Cadre i5: Four cores, no Hyper-Threading
  • Cadre i3: Two cores + Hyper-Threading
  • Pentium & Celeron: Two cores, no Hyper-Threading

With Kaby Lake, Intel is irresolute up its characteristic ready. In that location are at present multiple Pentium SKUs that back up Hyper-Threading, as shown in the chart below:

All of the new Kaby Lake CPUs take full HT support, whereas no Pentium chip previously carried that selection. This is not the merely improvement to the CPU core, though information technology's likely to exist the one users intendance the most most. Compared with the older G4520, Intel's top Skylake-derived Pentium core, the G4620 is 100MHz faster and offers support for Intel'south TSX-NI instructions, Retention Protection Extensions (MPX), and Intel'southward OS Guard platform protection technology. These are more often than not enterprise and developer features unlikely to interest a Pentium customer, but the 100MHz speed boost and HT support are both pregnant at this toll bespeak. The price, meanwhile, hasn't increased at all — both fries sell for $86 – $93 in one-1000 unit quantities. The major differentiation point betwixt the Pentium and the Core i3 is now the Core i3's support for AVX and AVX2, not Hyper-Threading.

AMD's upcoming Ryzen may accept given the Pentium an astute case of Hyper-Threading

It's not difficult to connect the dots on this 1. For half-dozen years, Intel has had a stable set of product families with clearly delineated features and little overlap between them. For 5 of those years, AMD'south ability to compete with Intel on the desktop has ranged from "not great" in 2022 to "pretty terrible" in 2022. Now, for the start fourth dimension in over half a decade, AMD believes it has a microprocessor that will let it to go toe-to-toe with Intel across at least some of the desktop market place, and Intel has suddenly discovered Pentium buyers might enjoy the creamy smoothness of Hyper-Threading.

Frankly, it'due south a smart movement for Intel to make. If information technology waited for AMD to launch Ryzen first, it risks initial negative publicity if AMD debuts a low-end knockout blow. Adding Hyper-Threading now gives Intel its own positive story to tell. The gains from HT should exist noticeable, since information technology typically improves operation by xv-xx% and there'south no shortage of desktop workloads with back up for dual cores with Hyper-Threading, since that's the virtually mutual laptop CPU configuration and the laptop market is significantly larger than the desktop space these days.

Prior to Ryzen, the weak CPU performance offered past AMD's APUs and low-end desktop CPUs gave Intel fiddling reason to push Hyper-Threading farther downwards its stack. With each AMD Bulldozer-derived CPU core worth roughly 60% of 1 Intel CPU cadre, AMD was forced to apply quad-cores to compete against Intel's Pentium and Celeron chips. AMD now has six-and-eight-core chips price against the Core i3, to give you an thought just how lopsided the comparisons have gotten. Only with Zen, in that location was a risk AMD would launch a dual-cadre + SMT CPU that mopped up the Pentium and Celeron, especially if AMD'due south Ryzen cores in this price bracket include AVX and AVX2 support.

Competition is a beautiful matter. Hopefully Ryzen is a strong enough chip that we won't merely run across Intel improving its cheapest CPUs.
