Haswell has been a part of the CPU market for quite a time from now and now when it is about to complete one full year of its life span, we have got some new refreshed CPUs based on same 22nm Haswell micro-architecture. The Part-I of this article covered the i5s and i7s of the Haswell refresh base and we bring to you the sneak-peak of the rest of the Core i series CPUs belonging to the Haswell refresh lineup in this second part.

Why Haswell got a refresh?


The first wave of the Haswell micro-architecture based CPUs were launched at the Computex 2013 held in Taipei, Taiwan. And being based on a completely new architecture, it has been highly anticipated just like the Sandy-Bridge CPUs which succeeded the LGA 1156 Processors based on Clarkdale and Lynnfield architectures. But unfortunately, unlike Sandy-Bridge, Desktop Haswell’s failed to impress the enthusiasts as well as end users since the desktop CPUs didn’t prove to be a potential upgrade compared to previous Ivy-bridge chips and users seeking an upgrade from their Ivy-Bridge based CPUs passed on the Haswell since the lack of features worth a new motherboard (featuring LGA 1150 socket) and the CPU as well. The mobile CPUs did impress since it claimed to improve the battery life and the 45% faster Integrated GPU dubbed HD 4600/Iris®/ Iris Pro® compared to older HD 4000 did give a boost in performance for Ultrabooks® which can’t afford to house in a dedicated GPU for the sake of dimensions, heat emission and battery life. The mainstream i5s belonging to the Haswell lineup had exact same specs as the Ivy-Bridge alternative barring the iGPU. And the i7s had the same story. Neither the shared level 3 cache, nor the clock frequencies were boosted. Though the top variants of the i3s featuring Haswell micro-architecture did have an extra MB of Level 3 cache and a +200 MHz boost in base clock. But the inflated price tag left least to be bothered. Therefore, Intel decided to launch to launch some tweaked Haswell CPUs along with 5th Generation core processors based on 14nm nodes and codenamed “Broadwell” but the 5th Gen cores were unfortunately postponed to be launched Q2 this year and the month which was scheduled to mark the launch of the Broadwell along with Haswell “Refresh” CPUs will now witness the launch of Haswell “Refresh” alone.

The “Refreshed” lineup

Since the launch of Haswell Refresh is around the corner, we bring to you the quick preview of the Core i series CPUs that will be part of the Haswell refresh lineup in a two part series. Here’s the 2nd Part preceding the 1st One in which we included the flagship i7 and i5 replacing the older flagship i7-4770 and i5-4670. The K series CPUs aren’t declared by Intel yet, therefore we haven’t included the K SKU CPUs in the preview. This time we bring to you the rest of the core i series lineup, which are part of the Haswell refresh SKUs.

Intel Haswell Refresh Core i Series Desktop Chips Specifications:

Name Base clock Boost clock Shared cache # of cores # of threads Max. TDP Compatible chipset
I3-4150 3.5 GHz 3 MB 2 4 54W 8 series/9 series
I3-4130 3.4 GHz 3 MB 2 4 54W 8 series/9 series
I3-4350 3.6 GHz 4 MB 2 4 54W 8 series/9 series
I3-4330 3.5 GHz 4 MB 2 4 54W 8 series/9 series
I3-4360 3.7 GHz 4 MB 2 4 54W 8 series/9 series
I3-4340 3.6 GHz 4 MB 2 4 54W 8 series/9 series
I5-4460T 1.9 GHz 2.7 GHz 6 MB 4 4 35W 8 series/9 series

Just like the results in Part-I of this article, each variant replaces a particular Haswell variant and features 100 MHz higher clocks. To sum here we go,


This Haswell refresh i3 features +100 MHz frequency boost over the older i3 in this range which was the i3-4130. Same 3 MB shared Level 3 cache, and same two cores with Intel’s Hyper Threading tech which enables each core to execute two threads therefore making a total of 4 threads from the two cores. The TDP remains same as i3-4130 i.e. 54W and would be compatible with 8 series and 9 series chipsets.


Though i3-4330 is the CPU which the i3-4350 would replace, but the former was the first CPU in the Haswell lineup and since the Sandy Bridge architecture to have a larger 4 MB of L3 cache versus the older legacy 3 MB for the top end Ivy-Bridge based i3-3250. Same +0.1 GHz boost and rest all same specs.


This flagship i3 of the Haswell refresh lineup would replace the older flagship i3 of the Haswell lineup, which was the i3-4340, i3-4340 had 100 MHz higher base frequency over the second in command of the i3 lineup, the i3-4330. Likewise, the i3-4360 (which would replace the i3-4340) would have a 100 MHz higher base frequency over i3-4330 (3.5GHz) replace which is the i3-4350 (3.6 GHz). Rest all remains same just as expected.


The i5-4460 (which is the replacement for the i5-4440 clocked at 3.1 GHz and turbo frequency of 3.3 GHz) has a 3.2 GHz base which is boosted up to 3.4 GHz and matches the base clock of the flagship i5, the i5-4670K. The “T” variant is a low TDP variant of the i5-4460 which has a mere 35W of TDP which is ideal for office PCs which are meant to be efficient as well as zippy enough. The base frequency is clocked at 1.9 GHz and Turbo boost 2.0 dynamically boosts it up to 2.7 GHz. But except the lower TDP and base and boost clocks, the i5-4460T doesn’t have any less features than its 84W sibling, the i5-4460. But it would be not right to compare them since they both aim to target different sectors and usage. The i5-4460 is aimed for power users who have a tight budget but want to invest in a monstrous dedicated GPU and want a CPU that doesn’t bottleneck their Graphics card yet be in their budget. While the i5-4460T would provide low powered performance for home and office use.


The story remains same, +100 MHz boost over the previous CPU and keep the prices same. Though the Broadwell CPUs would provide better features over Haswell and Haswell refresh, but since they are delayed to be launched therefore people who want to get a new build based on Haswell micro-architecture should definitely look into the Haswell refresh lineup since the mere performance boost in clock frequencies won’t be dominant over the older Haswell counterpart but definitely be more value for money. Not to mention Intel tightened the restrictions on non-K CPUs over-clocking in Haswell architecture, therefore one may consider to wait and invest in Haswell refresh. But at last, the consumer opinions matter, so what is your opinion ? Do tell us in the comments.
