Intel Haswell: here’s what you need to know

Intel Haswell

Intel Haswell Mobile lineup:

Mobile devices are what Intel is really targeting with Haswell. Mobile chips mostly come with low TDPs and faster iGPUs. The chip maker hasn’t released the ultra-low power ‘U’ series SKUs and SoC style ‘Y’ series SKUs right now but we’ve ‘H’ series and ‘M’ series processors. Current, mobile Haswell lineup only includes Core i7 models and no Core i5 or Core i3 models. There is a total of ten of these mobile processors which are equally divided into H and M series.

All the M-series SKUs come with Intel HD 4600 graphics including a 1000 USD Core i7-4930MX CPU. This series hits a lowest of 37W TDP. In mobile systems, the maximum TDP is never touched in real life implementations. Notebook designers usually use a fraction of the actual TDP of these chips.

The H-series mobile SKUs have slightly lower base clocks but three of them come with Iris Pro 5200 graphics making them perfect for workstation-type notebooks. Intel is basically targeting the NVIDIA GeForce GT650M’s performance with their Iris Pro so anything with the Iris Pro 5200 should be good enough for light professional tasks.
