Is buying a Haswell laptop worth it?

Haswell (microarchitecture) - Wikipedia

Compared to Ivy Bridge:

Approximately 8% better vector processing performance.[9]
Up to 6% faster single-threaded performance.
6% faster multi-threaded performance.
Desktop variants of Haswell draw between 8% and 23% more power under load than Ivy Bridge.[9][10][11]
A 6% increase in sequential CPU performance (eight execution ports per core versus six).[9]
Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000).[9]
Total performance improvement on average is about 3%.[9]
Around 15 °C hotter than Ivy Bridge, while clock frequencies of over 4.6 GHz are achievable.[12][13][14][15][16][17]

According to this, there’s not much difference in Haswell. Is it worth paying $70 or more for laptop with one, compared to Ivy Bridge?

Haswell dates from 2011. Skylake was released just this past August.

Just what are you planning to do?

In general I’ve found that notebooks that tend to run hot often have shorter lifetimes. It usually pays to go for newer, lower wattage power CPUs in notebooks.

I don’t push the laptop very hard, I guess. I don’t ask great game performance, and even cheap laptops have graphics chips now that rival the mid-tier cards from 10 years ago, so many games work. I think I probably have to get over myself and either go with the slower Haswell, or get an Ivy Bridge, which will be more in the price range I wanted, I think.

About the cooler CPUs, do I read the article above correctly, that Haswell is actually hotter?

Just for the record, if this thread is found again, I’m told by my IT friend that Haswell is a good jump in power management, especially when it’s essentially idle, and it’s not to be judged just on the numbers I posted.

Here’s a great comparison of the Haswell and newer Broadwell CPU architecture-
