The cheapest of the group is the ProBook 455 G4 with a starting price of $500. This unit sports a 15.6-inch LED backlit screen with a choice of 1,366-by-768 and 1,920-by-1,080 resolutions. It comes with a discrete Nvidia GeForce 930MX graphics chip with its own dedicated 2GB of DDR3 VRAM while the laptop’s processor provides an additional integrated Radeon graphics component.
That said, this laptop offers options for the seventh-generation quad-core AMD A10-9600P APU (1.8GHz), the A9-9410 APU (1.8GHz), and the A6-9210 APU (1.8GHz). These chips are backed by up to 16GB of DDR4 system memory clocked at 2,133MHz, and various storage options spanning hard drives, solid state drives, and hybrid drives. The optical drive options consist of a DVD burner or just a standard DVD reader.
As for connectivity, this laptop includes two USB 2.0 ports, one USB 3.0 port, one USB 3.0 Type-C port, an Ethernet port, VGA output, a headphone/microphone combo jack, and an SD card reader. Other features include a built-in 720p HD webcam, a full-sized backlit keyboard with chiclet keys, and integrated stereo speakers.
The most expensive laptop of the group is the ProBook 470 G4 with a starting price of $750. This model is packed with a 17.3-inch LED backlit screen with a choice of 1,600-by-900 and 1,920-by-1,080 resolutions. There doesn’t appear to be a discrete graphics chip, so customers will have to rely on Intel’s integrated HD 620 graphics component supplied by the processor.
This time around, the CPUs are all seventh-generation dual-core Intel Core processors. The choices consist of the Core i3-7100U (2.4GHz), the Core i5-7200U (2.5GHz), and the Core i7-7500U (2.7GHz) processors. The “U” in the name is Intel’s way of saying that these processors consume very little power so the laptop’s battery isn’t eaten up within hours. The average power usage of all three processors is 15 watts whereas a desktop processor can consume up to 140 watts.
As with the previous laptop, this model provides two memory slots supporting up to 16GB of DDR4 system memory clocked at 2,133MHz. It also has a number of storage options spanning hard drives, SSDs, and hybrid drives along with the same two optical drive options. Everything else connectivity-wise appears to be the same as well.
