HI all:

 My name is John, I am a developer of Thunderbolt 3 related products.

Here's my study result & opinion.

1. I did tons of tests in Games ( Far Cry Primal , Witchers, COD,) & Benchmark Utility ( Heaven, Valley, 3Dmark & Compubench  ), I see no FPS & Performance Gap between the what so called 2200MB and 1100MB. If there's anyway or method that you guys can provide to proof, let me know, I'll do the test again. and In this case , in the real world, w/o the gap, what will be the purpose to provide the solution as mentioned above?  A solution is to fix the problems and I found there's actually no problems no gaps between these C2D Bandwidth.

2. TI82 were the old design which had been caused ghost key, USB devices lost & not comply with the latest power delivery 2.0, 3.0 requirement. According to this, TI 65983 were suggested by Intel and mainly to solve those issues. I strongly do not suggest to buy the TI82 model. I am not the only one, Intel request all players to adapt the 65983 and more over Apple simply Block 65982 by their MBP Late 2016 model. To cause the 2200mb /1100 mb is FW. while Launching TI82 Model was attached the Old FW, now since 83 is current model, it attached the latest FW, Old/NEW FW caused this difference. ( ** but for our real tests, just Numbers , again, No performance & FPS gap )

3. Intel 22GB Bandwidth, it is accurate Bandwidth,  32GB is the electrical bandwidth. Please don't mix it.  Thunderbolt 3 provide the 40GB bandwidth with  DATA 22GB ( Max ) + DP signal remained  or DP signal ( 32GB ) + Remained Data ( 8G ). in this case, you may say, PCIe x 4 32GB ( Electrical ) Go through the Thunderbolt 3 switch & Thunderbolt 3 Cables, the accurate real  Data will be 22GB. I can cook the FW, Even I setup to PCI-e Bandwidth to 40G, but actually the alpine Ridge & Cable width is only afford 22G in the end. 

4. Intel may update the FW, I had no idea after updated what the CUDA Z # is going to be. But again, I tried the 2200mb/1100MB and I see no difference. If I got the FW updated, I'll let everybody know here and I'll do the tests again to compared with the recent data. or Intel will not update the FW in the end.

The reaction.... when you have Thunderbolt 2  eGPU:

ϟ AKiTiO Thunder2 + EVGA GTX 1060 6GB SC Gaming (macOS Sierra 10.12.4 and Windows 10)
MacBook Pro (Retina, 15-inch, Later 2013) 3.2GHz Quad Core Intel i7-4750HQ / 8 GB 1600 MHz DDR3 / 256GB SSD + 1TB
mini eGPUPCI Express vs. ThunderboltMac CAN gameGaming Laptops vs. MacBook Pro with eGPU

HI all:

Here's my study result & opinion.

You should repeat again your test focusing on  demanding benchmark/games scenes. You will notice the difference in the daily usage if you constantly ask your setup to run full capability. Check again the minimum FPS in these scenes and compare the results. Also you should focus on benchmarking the FrameTime instead only max/min/average fps!

After that TBE is under constant upgrade pressure, it did not surprise me to Intel and manufacturer force the upgrade blocking the firmware. As same as Win10 forced people to upgrade, not only the os but also the hardware!!!

HI:

1.  Thanks for your valuable suggestion, guide me to have a deeper test or any test value  you would like to see. I have many Hosts & Cards may support to clarify this issues.

2. FW divided to 2 types, one is eGPU and  the other is PCI-E. I have both, I can make Ti83 Board to be an PCI-E box and running CUDAZ to be 2200mb. But the side effect is the "Unstable Hotplug & Play ". and once during the application running, suddenly remove the connection will cause the system Hang or reboot request.  I do not see any real world performance drop and enjoy the stable hot plug & play.

3. Intel Thunderbolt 3 certification is like this. If you submit the device is an eGPU, you have to use the eGPU FW, and during the certification process, Lab will exam the design, circuit & VGA compatibility. If I submit my device as an PCI-e Box and I have to choose the PCI-e FW and the device will be attached with an PCI-e Card ( Not GFX ). Certificaiton protocol is different than the eGPU's. 

4. Considering the stability & no performance gap ( or not apparently gap , at least not 50% drop ) and more over we are actually running a GFX externally, I have to set the device to be a eGPU FW.

I had tested Razer Core 2200mb which is similar result with the 1100mb one, don't understand why I need to have Thunderbolt 2 eGPU? even I have thunderbolt2 eGPU, how will I have the same test condition to compared with TB2 & TB3 performance by using different Hosts? TB2 has to be link with a TB2 Hosts, such as MBP2015. compared with MBP2016 different CPU, UEFI, is it a meaningful comparison? If I lost something or concept goes wrong, kindly teach me.
