With the launch of the new GeForce 30 series, PCI Express 4.0 performance has come up into the discussion. To find out exactly what we're talking about, we've taken a deeper look.
Without attaching additional power cables, how much can a PCIe x16 graphics card draw from the motherboard's slot?
Is it 25W, 75W, 150W or up to 300W?
Last year, we briefly looked at external GPUs when we reviewed the Aorus GTX 1070 Gaming Box attached to a Kaby Lake-powered ultraportable. Now that Intel's 8th gen CPUs are widely available in a range of ultrabooks, with significant performance gains in hand, it's the perfect time to revisit eGPUs and determine whether the hard CPU bottleneck still exists in most games.
With the new Alienware 13 you get a gaming-class portable machine with the added benefit of connecting the Graphics Amplifier. The Amplifier houses a standard desktop GPU and power supply. When it’s plugged in, the mobile GPU in the laptop is disabled, and all the graphics power comes from the Amplifier, improving graphics performance substantially.
