Mainstream Haswell Processors

Intel successfully launched 4th Generation 'Haswell' processors for desktop and mobile PCs in June of this year. The new architecture heralds better performance, especially with respect to graphics, and lower energy usage: a win-win situation for anyone contemplating a new PC. But with plenty of 3rd Generation 'Ivy Bridge' stock still in the channel, Intel, somewhat sensibly, launched premium Haswell chips first, promising mainstream parts in the near future.

That near future is now, September 1, as the chip giant is rolling out a comprehensive number of new chips in one fell swoop. Most are destined for the desktop, and the purpose of this TekSpek is to explain how the new models fit into the existing CPU structure. The table below lists the majority of new processors.

Desktop analysis

What's immediately apparent is that Intel is delivering on its intent of providing mainstream Haswell 4th Generation processors. At launch, Intel limited supply to premium chips that touted four cores. A single Core i7-4771 and two Core i5s continue to flesh out this part of the product portfolio, and the top-of-the-line 4771 is now frequency-identical to the overclockers' favourite, the existing Core i7-4770K. The only difference is that the new chip is multiplier-locked.

But the real news rests with the availability of Haswell-based Core i3 and Pentium-class chips. These processors offer two cores and up to four-thread processing ability, thus making them a good choice for mainstream PCs. There are at least five new Core i3 additions, differentiated on the basis of frequency and power ratings. All naturally use the LGA1150 form factor which also debuted in June.

Intel hasn't forgotten about last-gen Ivy Bridge, either, as two new chips make an appearance today - the Core i5-3340 and low-power Core i5-3340S. Potential purchasers who are looking for a 4th Gen Haswell Core processor need to ensure that their chosen chip's model number begins with a '4' - Ivy Bridge parts begin with a '3,' denoting 3rd Gen status.

Yet even Core i3 chips are sometimes deemed to be too expensive for budget machines, so this is why Intel is also introducing five Pentium-designated processors that also leverage Haswell technology. Limited to two cores and without the hyperthreading present on the Core i3s, these Pentiums are a very good fit for inexpensive systems that have no problem in offering excellent everyday performance for a wide variety of tasks.

Much like the new Core i3 range, Pentium processors are sub-divided via frequency and power ratings, with those suffixed with a 'T' designed for low-power usage. Historically T- and S-class Intel chips have been ideal choices for home-theatre PCs and we see no reason why this shouldn't continue.

The introduction of at least 15 additional desktop CPUs further cements Intel's desire to move its product stack over to the best Haswell architecture. Those purchasing any of the above-listed chips will be safe in the knowledge that they all feature cutting-edge technology inside.

Mobile analysis

The situation for new Haswell-based mobile chips - those that go inside laptops and Ultrabooks - is somewhat different. Intel focussed on delivering a wide range of mobile processors in June, with lower-end models very much to the fore, and this means the mobile update certainly isn't as robust as the desktop's.

That said, at least a trio of new mobile processors are launching alongside the glut of desktop-bound chips. Using two cores and also taking advantage of hyperthreading, the new Core i7 and Core i5 parts provide laptop manufacturers with even more choice when specifying a new range of machines. Scan expects Intel to roll out a slew of further mobile processors in the next few months, thereby adding to the 20-plus model range that is currently available in either tray or box (retail) form.

In summary, Intel is finally harnessing its best-ever microarchitecture for both the mainstream desktop and mobile markets. This is certainly good news for those looking to build mid-range PCs in the run-up to the holiday season as it provides consumers with more choice than ever before. Combined with the widespread availability of supporting motherboards based around a number of Intel chipsets, specifying an ideal build just became that much easier.

As always, Scan Computers is a premier Intel partner and will be stocking a comprehensive selection of retail processors. Please head on over to here to see our updated list.
