Alienware 15 R4 vs Alienware 15 R3 – what are the differences?

After we covered briefly the specs sheet of the Alienware 15 R4 high-end gaming series, we thought you would want to find out if there are any major differences between this bad boy and its predecessor – the Alienware 15 R3.

The first contrast that stands out comes in the hardware department. While Alienware 15 R4 is powered by 8th gen Intel Core processors including the latest overclockable Core i9 one, Alienware 15 R3 sports only up to a 7th gen Intel Core i7-7820HK (@ 3.8GHz) one. However, when we take a look at the graphics options, both support up to an NVIDIA GeForce GTX 1080 Max-Q (8GB GDDR5X). But when it comes to memory, Alienware 15 R4 stands out with the support of Intel Optane PCIe 3.0 x2 [60/120GB]. What’s more, here we have an upgraded cooling system featuring the Alienware Cryo-Tech V2.0 thermal technology.

Moving on, both laptops are 15.6-inch and offer a choice between Full HD (1920 x 1080)/ 4K UHD (3840 x 2160) IPS and TN panels. We notice another similarity in terms of dimensions – 25.4 mm thickness and 3.49 kg (7.7 lbs) weight. There is also no difference in the battery capacity – 68Wh for both of them. In addition, the connectivity options are also almost identical except for the 1x USB 3.1 Type-C port in R4 as opposed to 1x USB 3.0 Type-C in R3.
