A new review by 9 to 5 Mac. He doesn't appear to know that the I/O is on a separate Thunderbolt controller or the Asix ethernet driver. People in comments correct him. One commenter says you can use the Razer Core X in a vertical position because there is no air intake from the front, so you don't need to buy a longer cable if you want to place the eGPU on the floor under your desk.

He’s kind right actually, you’re right  because it has dual TB3 controller, putting high bandwidth io will not effect gpu performance but will ruin gaming experience once you hit bandwidth limitation because of pheriperals may dis and reconnect. Yes you can put it vertical but it’s not designed for so and i think i never see pcie slot mobo with Vertical Position, it has to be some meaning like in long term usage.

Yes, true. If you are constantly consuming the GPU and I/O bandwidth at the same time then naturally bandwidth becomes an issue. However, this is rarely the case. Most the time content (games, apps, files) will first load from the I/O or storage and then the GPU/CPU accesses the data from memory (RAM or VRAM).

It won't make difference to temperature or long term usage if you put the Razer Core X in vertical position. In any position the slot and screw keeps the GPU stable. Originally PCI/PCIE slots were designed for pizza box form factor computers. The slots have been reinforced ever since we started using tower cases and heavy GPU designs. There was a Gigabyte vertical eGPU chassis

Obviously if there was an air intake at the front of the Razer Core X then we would have better cooling and it would have to be used horizontal only.

A vertically mounted GPU works just fine. It helps reducing the Core X footprint for sure. I have used one in a Phanteks Evolv Shift in the past year. Cooling should not be an issue with air intake on the left side and exhaust on the right side and rear. You may want some rubber padding to absorb vibration if it's placed on a hard surface.

I’m not talking about thermal, but other like design wise, it’s for horizontal use not vertical and there’s also foot downside like other core models, of course users can use as they want. I even see user put it in a case lay down with its vent grill on the top. But it’s kind weird to me, since Core has also good aesthetic value. Just like using monitor vertical, for some it’s weird but for some users it has its own function. From components it’s also designed for horizontal use, those enclosure you guys showed is designed for vertical, so probably it’ll hold well, but we don’t know on Razer Core unless someone tried using it on vertical position on long usage.

I haven't got my Radeon VII yet as I'm waiting for the 10.14.5 to be released.

My Core X Chroma arrived a few days ago. I installed a GTX 1660 (Gigabyte's OC G6) and have been doing setup/testing on my 2017 HP Spectre x360 15 (i7-8550U, MX150, 16GB RAM, 512gb SSD). The installation process was pretty straightforward. I experienced consistent hiccups in all games before disabling the dGPU in Device Manager, which solved that issue. The laptop’s CPU has a -.100v undervolt. So far I’ve overclocked the GPU’s core to 2055MHz and it has been very stable. I have a mouse/keyboard plugged in, as well as an Ethernet cable. A few quick thoughts:

1. My main use case for this eGPU is running Adobe Lightroom. The improvements to performance are kind of interesting. Applying edits has become totally seamless no matter what I do to an image, whereas before there was perceptible lag in heavier edits. However, cycling through 24MP images at full resolution and loading them on a 4K screen is still not a smooth process, even with a good PCIe NVME SSD. This makes sense as cycling high res images can be a CPU-bound task from what I’ve read. Am assuming (but haven’t yet gathered data to show) that the CPU is able to hold higher clock speeds under load because the MX150’s thermals are now offloaded externally. Overall I'm pretty happy with the performance improvement for this use case and don't believe a higher tier GPU would offer further improvement. 

2. A lot of people are curious about volume under load. The case itself is very quiet and its fans spin at a low speed. Hence your overall noise level will depend on the GPU. Gigabyte's OC G6 1660 is a cool/quiet card to begin with, and it includes a silent idle mode that turns the fans off. Even with a mild overlock and at max fan spin, it doesn't output all that much noise (or let the card rise above 73 degrees even during a FurMark stress test). I definitely couldn’t hear the card over my laptop's fans. Will defer to those with more powerful GPUs about how much noise is generated in those cases.

3. It's irritating that you have to run Razer Central to disable the lights. I wish the default profile were configurable (as with Logitech's lighted peripherals) so that I could have one less piece of software running. The lights are nice enough but not a good fit in most office environments. 

4. Build quality is excellent, but be wary of the size/weight. I suggest you measure out your space in advance to be sure it will fit wherever you intend to keep it. 

Below are a few preliminary results on Windows 10.0.17763 with Nvidia Drivers R430.39: 

Deus Ex: Mankind Divided benchmark
- DX11, 1080p, High Preset: Average 50.7 FPS, Minimum 38.1 FPS, Maximum 66.0 FPS.
- DX11, 1080p, Medium Preset: Average 61.5 FPS, Minimum 46.3 FPS, Maximum 82.5 FPS.
- DX12, 1080p, Medium Preset: Average 45.2 FPS, Minimum 32.1 FPS, Maximum 61.9 FPS.

FurMark v1.20.5.0
- 4K Preset: 1529
- 1080p Preset: 3577

GFX Bench (All tests run in offscreen mode)
OpenGL:

- 1080p Aztec Ruins (Normal Tier): 13,144.7 frames
- 1440p Aztec Ruins (High Tier): 6,812.91 frames
- 1440p Manhattan 3.1.1: 12,365.2 frames
- 1080p Manhattan 3.1: 17,338.8 frames
DX11:
- 1080p Aztec Ruins (Normal Tier): 18,886.9 frames
- 1440p Aztec Ruins (High Tier): 7,475.31 frames
- 1080p Manhattan: 27,564.4 frames
DX12:

- 1080p Aztec Ruins (Normal Tier): 19,968.8 frames
- 1440p Aztec Ruins (High Tier): 8,129.59 frames

Let me know if there’s anything I can clarify or any other tests you’d like me to run.

has anyone compared any performance differences between the "normal" razer core x compared to the chroma version?
For about € 60 I could make the change, but I would like to understand if even small improvements could be made with the new version.

It's very unlikely, all TB3 eGPU enclosures perform about the same.

Thanks for the reply.
Reading the specifications on the razer website, the core x chroma is not for me and I stay with my core x "normal".
The internal dimensions are slightly different. The core x has a width of 60mm, the core x chroma has a width of 57mm.
I know they are minimal, but my gpu has a width of 59mm!

Are you sure that USB bus is just 5gbps? The specification on Razer's website it's show as USB 3.1 so it should be 10gbps.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
