Less than a year ago, the Toughpad 4K was wielding an Intel Core i7 3687U vPro processor, a dual-core part clocked at 2.1GHz to 3.3GHz with Hyper Threading support and 4MB of cache. But now that Broadwell-U is here, Panasonic swapped the CPU out with a Core i5 3437U processor, a slightly slower clocked part (1.9GHz to 2.9GHz) with less cache (3MB), but based on a newer microarchitecture. Like the CPU it's replacing, the Core i5 3437U is a dual-core chip with Hyper Threading support.
Panasonic also added an HDMI 2.0 input to the Toughpad 4K, which joins existing ports and options such as USB 3.0, 802.11ac Wi-Fi, Bluetooth 4.0, Ethernet, and mini DisplayPort. Other specs on the refreshed standard model include 8GB of DDR3-1333 RAM, 256GB solid state drive, NVIDIA GeForce GT 745M graphics, HD 720p front-facing camera with microphone, Windows 8.1 Pro 64-bit, and various other bits.
Of course, the real treat here is the 20-inch 4K (3840x2560) display with multitouch support and LED backlighting. That might be a little on the large side for most home consumers, but it's business users that Panasonic is truly targeting here. A tablet like this can be used in a number of different fields, such as video editing, architecture, design, photography, and healthcare.
Panasonic says the refreshed Toughpad 4K tablet will be available in July for $2,999.
