Lenovo's ThinkPad series just got a little bigger. The company unveiled the new ThinkPad P50 and P70 mobile workstations at SIGGRAPH 2015 in Los Angeles Monday. Even though these new models bear the ThinkPad name, it looks like they're going to try to take that well-known line of laptops to the next level.

That's because the P50 and the P70 are the first to come with the new Intel Xeon Processor E3-1500M v5 to give the machines lots of speed. Both laptops also have Nvidia Quadro GPUs for graphics and X-Rite Pantone color calibration to make sure the colors on the screen look the way they should throughout the lifespan of your device. The P50 and P70 also come with a new Flex Performance Cooling system designed to keep your machine cool and running smoothly for however long you use it.

Getting down to the individual laptops, the P70 comes with a 17-inch screen. With up to 64 GB of DDR4 ECC memory and up to a terabyte of SSD storage, the P70 has the most memory and storage on a mobile workstation ever, according to Lenovo. The P70 can also support up to four storage devices, comes with two Intel Thunderbolt 3 ports and has a 4K UHD display or optional FHD touch. You also have the option of adding a DVD-RW drive to the device, according to The Verge.

The P50 is the thinner and the lighter of the two with a 15.6-inch UHD 4K display. In fact, it's the thinnest and lightest full-function mobile workstation Lenovo has ever released, according to the company's announcement. The P50 doesn't come with the optical drive option, and only has one Intel Thunderbolt 3 port, but other than that, it's basically the same as the P70, according to Ars Technica.

The P50 begins at a price of $1,599, and the P70 begins at $1,999. They are both scheduled to go on sale sometime in the fourth quarter of this year.
