The P1000 is equipped with a 640 CUDA core Pascal GPU, 4GB GDDR5 of onboard memory and advanced display technologies, all of which are tightly packed inside a low-profile form factor. In addition, it supports up to for four 4K displays with a native resolution of 4096x2160 (60Hz) and does not require any additional power connector, as its maximum consumption is quoted at just 47W--less than half of what the P4000 pulls out.
