Review of this 10Gigabit Ethernet PCI-e card

The Edimax EN-9320TX-E card also supports the NBASE-T standard, this means that depending on the cable and its length, it can synchronize at speeds of 2.5Gbps and 5Gbps. Therefore, you will not only be able to sync at 100Mbps, 1Gbps and 10Gbps, but also at intermediate speeds of 2.5Gbps and 5Gbps.

This network card incorporates auto-negotiation, depending on the cable and the distance will automatically synchronize at one speed or another. Of course, it is compatible with Auto MDI / MDIX, so we will not have to take into account if the network cable used is parallel or crossed, the card will automatically adjust to connect to switches, routers or other PCs directly.

This Edimax EN-9320TX-E card allows Jumbo Frames of up to 9K, this means that if we use Jumbo Frames in our network we will obtain higher speed, since we will have to send fewer packets, and therefore, fewer headers. This new card also supports the 802.1Q VLANs standard, and of course 802.1P for QoS priority queues.

The Edimax EN-9320TX-E is fully compatible with Windows systems, including Windows 10 and Windows Server versions. It is also compatible with Linux systems with kernel 4.x, 3.x and 2.6.x both 32-bit and 64-bit. This card also incorporates compatibility with VMware ESXi 6.0, 5.5 and 5.1, it is also compatible with Microsoft Hyper-V, Linux KVM and VirtualBox.

Main technical characteristics of the Edimax EN-9320TX-E card

  • Support for 100BASE-TX, 1000BASE-T, 2.5GBASE-T, 5GBASE-T standards (Support NBASE-T, 10GBASE-T)
  • 1 RJ-45 port with speed up to 10G.
  • Incorporates support for 802.1Q VLANs and also 802.1P QoS
  • PCI Express 2.0 x4 interface.

In RedesZone we have made a complete video explaining the main characteristics of this 10Gigabit Edimax EN-9320TX-E network card, a device to take into account if you need to update your network to 10Gigabit.

Once we know the main characteristics, we will see its box and also the network card itself.

External analysis

This 10G Edimax EN-9320TX-E network card comes in a small, white box. On the front of the box we find the main specifications of the Edimax EN-9320TX-E, such as that it is 10 Gigabit, and that it incorporates a low-profile bracket for installation in servers.

On the left side of the box of the Edimax EN-9320TX-E network card we find the contents of the box, the main features, such as that it is PCI-Express 2.0 x4 and that it supports 802.1Q VLAN and 802.1p QoS, as well as the system requirements.

On the back of the box we find the main features of the 10G network card in different languages, but without going into too much detail.

This 10G Edimax EN-9320TX-E network card is perfectly protected by a plastic in the box, the contents of the box are as follows:

  • 10 Gigabit Edimax EN-9320TX-E network card
  • Quick installation guide.
  • CD with the quick installation guide, manuals and also the necessary software to start up the card.

This Edimax EN-9320TX-E network card has a gray heatsink on the top, ideal for keeping the temperature of the chipset of this card under control. At the bottom we find all the circuitry of the network card, and also a sticker with the model and the different certifications that the network card has passed.

On the front of the Edimax EN-9320TX-E network card is where we find the RJ-45 connector, right next to it we find a link and link activity LED, we also find an LED that will quickly indicate the speed synchronization of the network card with the switch / router where we connect it.

One of the strengths of the Edimax EN-9320TX-E card is that it incorporates a low-profile bracket, ideal for installing it in servers without having to buy the bracket in question, because it already comes in the box by default.

So far we have come with the external analysis of this 10 Gigabit Edimax EN-9320TX-E network card, now we are going to go to the test laboratory to check its performance.

Test laboratory

The manufacturer Edimax has provided us with two units of this high-performance Edimax EN-9320TX-E network card. We have tested these network cards with a professional 10G Edimax XGS-5008 switch of which you will soon have a complete analysis in RedesZone.

Once we have installed the Edimax EN-9320TX-E network cards in two computers, one with Windows 7 64-bit and the other with Windows 10 Pro x64, we have connected it to the 10G switch with a Cat6 cable. We must remember that Cat6 cables support 10G speeds over short distances, we have not exceeded 1.5 meters of this type of cable.

Tests with the Edimax EN-9320TX-E card

If we go to the center of networks and shared resources, we will see the status of the local area connection, as you can see we have a 10Gbps synchronization, which we already expected. On the Windows 10 computer we also have 10Gbps synchronization. The card configuration is auto-negotiation and we have activated the Jumbo Frames at 9K.

Regarding the configuration options of the card, as you can see we have the possibility of activating the Jumbo Frames, and also modifying the speed thanks to NBASE-T.

The first performance test we have carried out is to perform a transfer between a Samba server hosted on a PC with Windows 7 and a 10G card, plus a NAS server with a 1G card via Samba. All this at the same time.

As you can see, the total throughput is 305MB / s, approximately 2.5Gbps, and it is that both the hardware of our equipment and the hard drives are bottlenecking, the network card is only at 3325% of its capacity. Here’s another test with CrystalDiskMark pointing to the network drive with the 10G computer and card:

If we carry out a test with iperf3 we can verify that we have achieved different speeds if we use different sizes of TCP windows, this is due to the hardware we are using, and we have not been able to achieve the 9-9.5Gbps that we should achieve under normal circumstances. However, you can see how we are able to send data up to 7.66Gbps:

We must bear in mind that with the hardware used we have not been able to squeeze the 10G port, so if you are going to buy this card you must have a fairly powerful computer to be able to squeeze its maximum speed. This network card is aimed at advanced home users and also SMEs, where we need more speed than 1Gbps. To give you an idea, a SATA3 interface where we normally connect SSDs and hard drives has a maximum speed of 6Gbps, and this network card is capable of providing up to 10Gbps of speed, almost double.

In small and medium-sized businesses there is almost always a NAS server or file server with great hardware, to give ultra-fast data delivery to all employees. In this way, you will be able to squeeze the maximum speed of its 10G port on this card.


This network card incorporates a CD with the drivers for the different operating systems, although we can always access the manufacturer’s official website where we will find the latest version. We have verified that the Windows 7 Professional SP1 x64 and Windows 10 x64 drivers work perfectly. An interesting detail is that this CD works for both the Edimax EN-9320TX-E and the Edimax EN-9320SFP + models, which have an SFP + fiber connector and not a copper Ethernet one. In both operating systems we have had to install the manufacturer’s own drivers, the operating system has not been able to detect the card and install the necessary drivers by itself.

Once you have seen the main features of this card, and the performance that we have achieved in the tests, we will explain the strengths, weaknesses and conclusions.


  • One RJ-45 port with 10G speed and support for NBASE-T (2.5Gbps and 5Gbps).
  • Performance achieved in tests, we have achieved the expected speed for this type of card, although we have not been able to get the most out of it.
  • Includes a low profile bracket to fit low boxes.
  • Ease of installation, simply click into an available PCIe 2.0 x4 port.
  • It is compatible with any operating system even if it does not include the drivers on any CD, such as Windows 7 and Windows 10 (among others).
  • Passive cooling, so the noise is 0
  • Price: excellent, it costs around 110 euros, a real bargain considering the characteristics.

Weak points

  • We will not take advantage of the maximum performance that this card is capable of providing us if we do not have very powerful hardware, but is that a problem? Of course not, therefore we have not found any weak point to highlight.

Last conclusions

This Edimax EN-9320TX-E network card is a top of the line in its field, it not only incorporates 10GbE technology, but is also compatible with NBASE-T technology. Another very important feature, especially for servers, is that it supports 9K Jumbo Frames.

The performance of this card is excellent, in fact, in few cases we will be able to squeeze the maximum 10Gbps of speed from its RJ-45 port. If we are going to transfer data at high speed, surely the bottleneck is found in the data interface of the SSD / hard drives, or else in the server’s own hardware. In fact, it is very likely that you will have to modify kernel parameters to try to maximize the speed that this card allows you.

The price of this card is around 110 euros, an excellent price since we can update our equipment with 10G connectivity and make the most of our local network. Whether you are a home user or a company, this network card for this price is ideal for you, in fact, we did not expect this network card to drop below 200 euros, so this is great news.

If we take into account the characteristics, the possibilities and the performance of this Edimax EN-9320TX-E card and the price, RedesZone’s assessment is as follows:

We hope you liked the analysis, if you have any questions you can put a comment and we will respond delightedly.
