eGPU PCIe 4.0.0 is a newer version of the PCI Express (PCIe) interface, which is a standard for connecting components to a computer’s motherboard. It is used to transfer data between devices, such as graphics cards, hard drives, and network cards.

Best eGPU PCIE 4.0 

Here a list of the best eGPU PCIE 4.0 to buy for better external graphics card performance:

Razer Core X Chroma

1- Razer Core X Chroma (The Best eGPU PCIE 4.0 Overall)

  • Port: Thunderbolt 3
  • Power: 700W + 100W
  • Compatibility: Windows / Mac
  • Pros: Design – Quality – Speed
  • Cons: USB port – Mac

Razer’s first model is a great example of their commitment to detail in design, construction, and performance. It’s a very solid machine and has an attractive RGB display that you can configure with Razer’s famous and user-friendly Synapse program. Its fast Thunderbolt 3 connectivity has been praised by many users. Unfortunately, some have reported that it doesn’t perform as well on Macs, limiting its compatibility. Additionally, for the price, it would have been nice to include a couple more USB ports for a more complete experience. Despite this, the model has a satisfaction rate of over 90%.

Sonnet eGPU Breakaway Box

2- Sonnet eGPU Breakaway Box

  • Port: Thunderbolt 3
  • Power: 550W + 87W
  • Compatibility: Windows / Mac
  • Pros: Power – Transfer speed – Compatibility
  • Cons: Compatibility with some GPUs – Noise

Sonnet is a well-known manufacturer for its high quality products at reasonable prices. The external box has enough power to accommodate GPUs up to 375W, although there may be issues with certain graphics cards being too large.

Be sure to check this before purchasing! Thunderbolt 3 boasts an impressive speed of 40Gb/s. It is worth noting that the GPU can become quite noisy when under heavy load.

Alienware Graphics Amplifier (9R7XN)

3- Alienware Graphics Amplifier (9R7XN)

  • Port: USB 3.0
  • Power: 460W
  • Compatibility: AlienWare PC
  • Pros: Plug’n’Play – Speed – Peripherals
  • Cons: Compatibility – Noise

This external GPU case is only compatible with AlienWare PCs, so you won’t be able to use it with your Windows or MacOS systems. This proprietary hardware choice allows the manufacturer to have a perfect control of its compatibility. Installation and connection of the machine is quick and easy, and up to 4 devices can be connected, as the four HyperSpeed USB 3.0 ports provide a blazing transfer rate.

Some users however have reported a considerable noise, and unfortunately it is not possible to modify the fan speed to reduce this. Some consumers are also not convinced by the characterful design, which is quite heavy (3.5 kg) and large in size. However, this is a matter of taste! All in all, if you have an AlienWare PC, this external GPU case seems very interesting, especially given its affordable price.

Final Words

In summary, while eGPU PCIe 4.0 may offer some performance improvements over previous versions, the impact may not be significant in all cases and will depend on the specific hardware and use case.


Does eGPU PCIE 4.0 Make a Difference with External HD/GPU?

Yes. It is make a difference:

  • Faster data transfer rates for external hard drives
  • Increased graphics performance from PCIe 4.0.0 graphics cards
  • Access to high-performance GPU processing power in a compact and mobile form factor
  • Thunderbolt 3 provides a high-speed I/O connection
  • Ability to connect up to six devices to the host system via a single Thunderbolt 3 cable
  • Access to external bus of the laptop for connecting PCIe-using components
  • Faster data transfer speeds compared to previous versions of PCIe

What are the Differences Between PCIe 3.0 and eGPU PCIe 4.0?

  • eGPU PCIe 4.0 allows for faster data transfer rates compared to PCIe 3.0
  • Thunderbolt 3 uses a USB-C connector, but not all host connections, cables and USB-C devices support Thunderbolt 3
  • Most eGPU docking stations require the host computer to have a Thunderbolt™ 3 port to connect to an external graphics docking station
  • Thunderbolt 3 (TB3) is Intel’s high-speed external I/O connection, capable of speeds up to 40 gigabytes per second (Gbps) via a compatible USB-C port
  • With the advent of USB-C and Intel Thunderbolt, external graphics cards are now the logical choice for users who need high-performance GPU processing power in a compact and mobile form factor
  • eGPU PCIe 4.0.0 is the latest version of the PCIe standard, which offers faster data transfer speeds than previous versions
  • In terms of external hard drives, eGPU PCIe 4.0.0 may potentially offer faster data transfer speeds when used with compatible hardware
  • In terms of graphics cards, eGPU PCIe 4.0.0 may offer slightly faster data transfer speeds compared to previous versions of PCIe

What are the best GPU enclosure brands?

We especially value Razer and SoNNet, as they are recognized for their placement on computer equipment and high quality standards.

How much does an eGPU cost?

Prices can vary depending on the number of ports, Thunderbolt 2 or 3 technology, OS compatibility and whether an external graphics card is on board or not. Prices range from $150 to more than $700.

How do I know if the graphics card fits in the case?

Manufacturers normally indicate compatible graphics cards. You can also check the max supported power for the GPU (eg 375W) and the dimensions.

AMD or NVIDIA for the graphics card?

AMD stands out above all on the entry-level and intermediate ranges, with excellent value for money. On the high-end, however, NVIDIA remains roughly unmatched, despite a high price.

How to install an external graphics card on a laptop?

The procedure requires following a manual. This is usually provided, or you can find many tutorials on the web. Make sure to carefully read and follow the instructions, to ensure a proper installation.
