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. And we bring to you the sneak-peak of the Core i series CPUs belonging to the Haswell refresh lineup.

 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 was 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 Haswells 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 exactly 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 1st part and 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.

Haswell Refresh Core i series lineup 

Name Base clock Boost clock Shared cache # of cores # of threads Max. TDP Compatible chipset
I7-4790 3.6 GHz 4.0 GHz 8 MB 4 8 84W 8 series/9 series
I7-4770 3.5 GHz 3.9 GHz 8 MB 4 8 84W 8 series/9 series
I5-4690 3.5 GHz 3.9 GHz 6 MB 4 4 84W 8 series/9 series
I5-4670 3.4 GHz 3.8 GHz 6 MB 4 4 84W 8 series/9 series
I5-4590 3.3 GHz 3.7 GHz 6 MB 4 4 84W 8 series/9 series
I5-4570 3.2 GHz 3.6 GHz 6 MB 4 4 84W 8 series/9 series
I5-4460 3.2 GHz 3.4 GHz 6 MB 4 4 84W 8 series/9 series
I5-4440 3.1 GHz 3.3 GHz 6 MB 4 4 84W 8 series/9 series



The Core i7-4790 would dethrone the i7-4770 and features a +100 MHz boost in base and boost clocks. The Shared level 3 cache and # of cores remain same. And the i7 would have a single replacement.


This i5 CPU would be the replacement for the flagship non K Haswell i5-4670 and has +100 MHz bump in base and boost frequencies as well. Other specs remain unchanged, but the base and boost clocks do match the i7-4770K’s stock clocks.


The i5-4950 would be directly replace the choice of non over-clocking gamers, the i5-4570 and features same +100 MHz base & boost clock increment.


This baby i5 would be replacing the 4430 and would prove to be a potential upgrade over the 3330 or the 4430 since the base and boost clocks are 200 MHz higher. And prove to be the best choice for guys on a budget.

Happily concluding

The fact that Intel did improve the performance of the Haswell lineup, though it was after 9 months from the launch, but still it is remarkable considering they are charging no extra premium for the higher clocks though, just a mere 100 MHzMHz, but it’s a hint that Broadwell may have some potential upgrades that would really make the Ivy-Bridge users to think about an upgrade. Therefore, we can expect that along with a die shrink one may get blessed with higher clocks in codenamed Broadwell CPU core i CPUs. What’s your opinion of the Haswell refresh lineup guys? Worth it or just a marketing gimmick? Tell us in the comments below.
