MacBook Pro Lightning Bridge GTX 780 TI play games

Notebook video cards have always been weak, external display appears to be a good idea, there are many manufacturers to try, but because of various constraints, especially the lack of uniform standards and short-lived. Intel 2011 introduced the Lightning high-speed interface, bandwidth doubled, from the initial 10Gbps to the second generation of 20Gbps, next year will upgrade to 40Gbps, plus it is essentially the PCI, DisplayPort fusion together, It seems to be the only place to get a standalone video card to your notebook. In fact, MSI, Silver Hin also demonstrated such a scheme, unfortunately can not solve the performance, hot plug problem, not to become a retail product. Even worse are system and driver support, especially as lightning devices are now mostly from Apple, and Apple is very demanding on driving. Since the manufacturers can't do it, we'll come to diy!. The squinks of the Tech Inferno Forum made a daring experiment and finally succeeded in using sonnet Echo Express iii-d chassis and pirate ship RM450 power to graft a powerful GeForce GTX 780 ti into a MacBook Pro Notebook, the channel is Lightning 2. The result is exciting: 1, full support hot plug. Install through bootcamp standard mode, boot into Windows, install drive, fix. 2, performance can play a 85–90%. Considering that the 2 bandwidth of the Thunderbolt is only 20Gbps, and less than One-sixth of the PCI 3.0 x16, this is entirely acceptable. For example, 3DMark Fire Strike, when the external running points 10410, in the general system running points 11096, the proportion of about 93%. Again for example Unigine Valley, the achievement is 60.2fps/2520, 73.1fps/3057,82% respectively. 3, the game speed is basically very fluent, can stabilize in 60+fps, but physx physical effect basically wants to close. For example, "Call of Duty: Ghost" the highest quality/1080p/2xaa 60+fps, "Tomb Raider" the highest quality/1080p/tressfx close 60-100fps, "Crysis" the highest quality/1080p/2xaa 80-90fps, "Biochemical surprise: Unlimited "Highest quality 108FPS. 4, external display system costs, depending on the graphics card is about 1500-2000 dollars. However, the notebook's own display graphics performance will be affected, loss of about 5-20%, such as Unigine heaven frame rate from 63FPS to 53FPS, "No Land" will drop frame led.
