The Onboard GPU
The x1.small is the "I Can See My House From Here" server - built for the Edge, but with a twist.
In addition to a solid 32 GB of RAM, and a fast SSD, we've boosted the networking setup to 10 Gbps NIC's (thanks to Intel X710 NICs) and replaced the processor with a flexible 4 core (8 hyperthreaded core) E3-1578L, which can burst to 3.4Ghz and includes an integrated graphics accelerator (the Intel® Iris™ Pro Graphics P580).
The Iris Pro Graphics P580 is an integrated graphics processor introduced by Intel for high-end Skylake-based processors. This GPU is Skylake's highest tier GPU incorporating 72 execution units as well as a large 128 MiB eDRAM of cache.
