Thunderbolt spec has PD specs for up to 15w for Thunderbolt accessories. For USB devices, the USB standard for power is utilized, typically up to 7.5w. So yes, all part of the Thunderbolt spec as far as how the PD behaves.

@@justme0098 Thanks for the info!

USB-C to HDMI. You can buy adapters or full length cables

You can daisy chain storage devices, yes. Always make sure to the put the most power hungry devices at the start of the daisy chain.

And even support dual 5K, 6K, and 8K!

Thunderbolt 5 will be able to transfer up to 80gbps of bandwidth for eGPUs

Did you use an active Thunderbolt 4 cable when connecting them and plugged it into the Thunderbolt 4 port?

@@GetThunderbolt Yes, I used active cable and pluged it on my tb4 port, but still no display. Is it because my processor didn't have integrated gpu?

@@GanJosie If that's the case, you can disable the integrated graphics in the BIOS settings of your system. This can be useful if you want to use the Thunderbolt port for display output and your processor doesn't have an integrated GPU. However, you should be aware that disabling the integrated graphics can lead to issues if you don't have a dedicated GPU.

@@GetThunderbolt The problem is otherwise, I actually used rtx 4070 Ti, but my processor didn't have integrated gpu, and I already used active thunderbolt 4 canle, but my thunderbolt 4 ports didn't show any display.

Any of the docks we reviewed in the video are great choices, but it really comes down to preference and budget. You can find all the certified Thunderbolt 4 docks and products here: thunderbolttechnology.net/products.

I have found there to be an issue with the handshake between the Windows and the thunderbolt card. I find that if I have all connected devices switched off on boot, there is a better chance of the ports showing up in the thunderbolt control centre, although this is still hit and miss. I would be interested to hear what other people's work arounds for this is.

@@nickyjay2009 Even with my devices that actually show up in device manager, you’re absolutely right - I have to have them turned on and plugged in before I even turn on the computer! Otherwise the thunderbolt chip on the host disables itself and goes to sleep and won’t wake up. What a joke. I guess this tech really does suck unless you’re using a Mac. I swear I’ve never had any issues using Intel or Apple silicon Macs with Thunderbolt. Nothing like what I’m seeing on a PC! This is downright embarassing for Intel.

You're still limited to 160Gbps in total with 80Gbps for data and 80Gbps for video. So when you use the bandwidth boost for 120Gbps on a monitor, that only leaves 40Gbps for the eGPU to utilize, so your speeds will be more limited versus using a monitor setup that doesn't require bandwidth boost allowing you the full 80Gbps of bandwidth for the eGPU.

Thunderbolt 5 products are on the way soon too!

That's a ways away, but we'll keep that in mind!

@@GetThunderboltmeaning? Sounds like you are confirming it for thunderbolt 7 at least.

Areca has a Thunderbolt 3 SAN solution that allows up to 9 users to be connected to the central storage, all through locally attached Thunderbolt network that provides block-level access to storage.

More details: By the way, I was planning to get a laptop with the latest CPU and have a Thunderbolt 4 port and then put in an external graphics card like a 4090 but they say it will cause a bottleneck. Will a Thunderbolt 5 cable solve this problem or should I get a laptop that has a Thunderbolt 5 port?

Yes it will work with Thunderbolt 4, but to get the benefits from Thunderbolt 5, you'll need to use Thunderbolt 5 devices.

@@sohaibsohaib8180 Thunderbolt 5 would absolutely help with this because it can drive double the bandwidth for your eGPU. If you want to utilize a solution like this, your best bet may be to wait for 2024 products to launch.

​​​@@GetThunderboltThank you very much for answering my questions. I don't think I can wait until 2024. I will buy a laptop that has Thunderbolt 4, and when Thunderbolt 5 release, I will try its cable(Thunderbolt 5 cable and device in Thunderbolt 4 Port), and if it can run the eGPU with a great FPS, I will not need to change it, but if it is not good, then I will think about buying either a desktop or a laptop that has Thunderbolt 5 port.

There could be issues with the monitor, in this case Thunderbolt isn't the problem. It's likely the laptop, cable, or monitor. I would try using it with a different cable first, then with another laptop, and finally contacting the company that makes the monitor to troubleshoot.

Thank you for looking at this. Embarrassingly, it was a driver issue. Apparently (as it turns out) you need a 2nd video driver for onboard video in addition to the dedicated GPU driver. Live and learn!@@GetThunderbolt

We're glad you got it all figured out!@@HikingWithCooper

Thunderbolt will support up to 240W

Assuming you purchased a Thunderbolt device, you should get a Thunderbolt cable with it, otherwise you can order a Thunderbolt cable. It's only necessary for a Thunderbolt device, otherwise you can still use USBC. You can use a splitter, adapter, or dock to facilitate that.

The only option currently that I'm aware of is using any Thunderbolt 4 laptop with the Plugable Thunderbolt 4 Quad display docking station.

@@GetThunderbolt In theory, how much data will be pushing through that thunderbolt 4 port on the laptop to the Plugable docket to run 4x4K at 60Hz? Isn't a 4k at 60Hz will required ~18Gb/s of bandwidth? Do you have a good article for me to read all about this HDMI 1.4 & 2.0, DP 1.2 & 1.4 and TB4/USB4 etc?

@@julyzerg1 given this is the only dock that supports it I would refer to this: plugable.com/en-ca/products/tbt4-udz So, while Thunderbolt 4 can deliver up to 40Gbps of data, the Plugable docking station can support 4x4K at 60Hz by distributing the data across multiple USB-C ports, each providing the necessary data bandwidth for each monitor. It is important to note that Thunderbolt 4 only guarantees a minimum requirement of dual 4K monitors at 60hz, but can go beyond that. You can also read these materials: www.intel.com/content/www/us/en/architecture-and-technology/thunderbolt/overview.html#tab-blade-1-1 www.thunderbolttechnology.net/sites/default/files/intel-thunderbolt4-announcement-press-deck.pdf www.intel.com/content/www/us/en/gaming/resources/upgrade-gaming-accessories-thunderbolt-4.html

There are several differences, most notably fixing DMCA security and upgrading minimum requirements, but they do not differ in bandwidth.

It's up to you and depends on what your laptop needs are. Thunderbolt 5 products will start to release in early 2024!

The main use case is for laptop users, but yes you can also achieve similar speeds in other ways. However, Thunderbolt also carries video bandwidth and can connect to your monitors too.

Yes absolutely. Thunderbolt is backward compatible with USB-C!

The bandwidth requirement for rendering images depends on the screen resolution and refresh rate. Higher resolutions and refresh rates require more bandwidth to transfer the necessary data to the GPU for processing. For example, 4K@120Hz requires approximately 2.7Gbps of bandwidth, but if you increase the resolution or refresh rate, the bandwidth requirement will also increase. This is because more data needs to be transferred between the CPU and GPU to render the images at higher quality and smoother motion. The bandwidth is also important for communication between the CPU and GPU. The GPU needs to receive data from the CPU and send back the processed frames to be displayed on the screen. If the bandwidth is not sufficient, it can lead to bottlenecks and performance issues. The Thunderbolt 5 (TB5) technology has the potential to address this problem by providing higher bandwidth and faster data transfer rates. However, it's important to note that the performance of the eGPU is not solely dependent on the bandwidth; other factors like the CPU, GPU, and software optimization also play a significant role. The role of the controller in eGPUs is to manage the data transfer between the CPU, GPU, and other components. It acts as an intermediary between the host system and the external GPU. While the controller does introduce some overhead, modern eGPU implementations have become more efficient, minimizing the performance impact. With the introduction of TB5, which offers higher bandwidth, it is expected that the controller's impact on performance will be further reduced.

@@GetThunderbolt Thank you so much for taking the time to reply to me! Regarding 1 & 2. But that's only if we use the laptop's built-in monitor, right? As far as I know, if we use an external monitor connected directly to the eGPU, then in this case the bandwidth will be used only for one way data transfer from CPU -> TB4 => GPU -> external monitor.

@@trysometech52 4K @ 120 Hz is not extremely performance heavy so I don't see sharing the bandwidth as being an issue. It's just important to keep in mind that your most performance hungry device should be first in the daisy chain for optimal results.
