So far H3C Magic NX54 disassembly is complete, and finally summarize the chip model.

NX54拆机评测

The following is a review of the H3C Magic NX54.

Packet forwarding performance test

Testing the packet forwarding performance can roughly understand the CPU performance, but this performance will be affected by the firmware function in addition to the hardware factor.

Using the MiniSMB tester, I350-T4 connects one network port to the WAN port of H3C Magic NX54 and one network port to the LAN port to test the 64byte packet forwarding rate from WAN to LAN. The result is the value in the red box in the following figure.

NX54评测

990Kpps, at which point the CPU usage averages 15.2%. (The forwarding rate for a gigabit port running full 64byte packets is 1488Kpps)

Two other routers, also IPQ5018, were brought out for comparison, as shown in the following table.

NX54拆机评测

H3C Magic NX54 is very close to Xiaomi AX6000.

At present, we have not encountered any IPQ5018 products that can run at full 64byte packet line speed. But even 500Kpps is enough. In the daily use of the network, various sizes of packets coexist.

The H3C Magic NX54 can run at full line speed at 256byte.

.256byte 下行

Look at line 7 of the above chart, it has reached 990Mbps, gigabit no pressure.

Three, wireless signal strength test

Signal strength test is used to use other models to compare, unless very lazy la.

The comparison model is Xiaomi AX6000.

NX54拆机评测

The two above are IPQ5018, 5G chip are a little different, H3C Magic NX54 with QCN9074, Xiaomi AX6000 with QCN9024. QCN9074 than QCN9024 a little more advanced, the difference is the wireless band capacity and OFDMA user number, other parameters are the same.

Both of them are external six antennas. The wireless signal strength is measured to see how much difference there is between the two.

Both the 2.4G and 5G wireless channels are set to 9 and 44, placed in the “WIFI” position in the figure below, after testing one off and move away, and then put the other in the original position to test the power on, to avoid interference and location of the two units placed close together is not absolutely uniform.

pingmian

The computer with Intel AX200 wireless card is placed in the above figure in four positions A, B, C, D. Each position each wireless signal recording time of 3 minutes, because the value of the signal strength is not a fixed value, but a curve that changes continuously every second.

The wireless signal strength test results of the two units are as follows.

NX54拆机评测

2.4G and 5G signals are stronger in the H3C Magic NX54 at point A, which is separated by a wall.

NX54拆机评测

At point B, two walls away, the 2.4G signal is still stronger with the H3C Magic NX54, while the 5G signal strength is about the same between the two.

NX54拆机评测

At the location of point C, which is 11 meters away in a straight line, the 2.4G signal is still strong for the H3C Magic NX54, and the 5G signal is also a little stronger for the H3C Magic NX54.

NX54拆机评测

Finally, downstairs in the D-point location, the 2.4G and 5G signal strengths of the two are basically the same.

From the four locations, most of the H3C Magic NX54 signal is stronger, but a strong signal does not necessarily mean that the speed is also fast. So the next step is to test the wireless speed!

 

Fourth, the wireless speed test in different locations

Wireless speed test also joined the Xiaomi AX6000 for comparison, using AX200 (using a set of antennas of ASUS PCE-AC88), Xiaomi 10, Xiaomi 11, Apple SE2, the four wireless clients for wireless speed test. The router’s WAN port is connected to a self-built speedtst speed measurement server. Because H3C Magic NX54 does not support 2.5G WAN port, in order to be a fair comparison, Xiaomi AX6000 WAN port with 1G network port.

The four clients are also measured in four different locations in the front, each location each signal connection speed test 6 times, and finally take the average value for reference.

The connection schematic of each device is as follows.

NX54 speedtest

1、AX200 speed measurement results

All the results are shown in the following table.

NX54拆机评测

The 5G averages are as follows.

NX54拆机评测

AX200 supports 160MHz, which makes even if point A, which is separated by one wall, point B, which is separated by two walls, and point C, which is 11 meters away in a straight line, this 5G downlink speed reaches the limit of the gigabit WAN port, when the bottleneck is not the 5G wireless, but the gigabit network port.

This is the advantage of supporting 160MHz bandwidth, of course, your network card or cell phone should be supported to do so.

The 2.4G average is as follows.

NX54拆机评测

The 2.4G speed at point C is obviously faster than the H3C Magic NX54, but downstairs at point D it is faster than the Xiaomi AX6000.

Perhaps you will have questions about why I test 2.4G speed only 2 locations? Because the measurement of 2.4G can only be tested before noon, other times to do 2.4G speed measurement will be very unstable, the maximum error can vary by 10 times, especially in the evening time period.

 

2, Xiaomi 11 cell phone speed measurement results

Xiaomi 11 also supports 160MHz bandwidth and also supports 4K-QAM (4096-QAM), making the maximum wireless rate higher than Intel AX200.

All results are tabulated below.

NX54评测

The 5G averages are as follows.

NX54评测

In the A and B points, Xiaomi 11 5G downlink speed are reached the limit of the gigabit network port, in the C point location of the two routers down to more than 600 megabytes of downlink speed, because the phone’s WIFI power is not as good as wireless network card ah. A, B, C three locations of the downlink speed of both about the same.

Downstairs in point D position, Xiaomi AX6000 is a bit faster than H3C Magic NX54.

2.4G average is as follows.

NX54评测

The difference between the two 2.4G is not much, and the overall view is that the Xiaomi AX6000 is faster.

3, Xiaomi 10 cell phone speed measurement results

Xiaomi 10 can only support 80MHz, so the wireless rate will be twice as low as Xiaomi 11.

All the results are shown in the table below.

NX54拆机评测

The 5G averages are as follows.NX54拆机评测

Xiaomi 10 speed measurement, at point A location, the downlink speed of the two is about the same, only 80MHz bandwidth, across a wall can also reach the limit of the gigabit network port.

At point B and C, the 5G speed of H3C Magic NX54 are faster than Xiaomi AX6000, but at point D downstairs, it was overtaken by AX6000.

 

4、Apple SE2 cell phone speed measurement results

Apple phones are not supported 160MHz, the highest rate is the same as Xiaomi 10.

All the results are listed below.

NX54评测

The 5G averages are as follows.NX54评测

 

At points B and C, the H3C Magic NX54’s 5G average speed is a bit faster than the Xiaomi AX6000, while downstairs at point D it is the Xiaomi AX6000 that is a bit faster.

The average 2.4G speed is as follows.

NX54拆机评测

Apple’s 2.4G Wi-Fi does not support 40MHz, so the 2.4G rate is relatively low one, which directly leads to a large reduction in speed.

Downstairs both speed is the same, at the C point position is H3C Magic NX54 fast.

 

Why use 4 different devices to test the speed of the wireless router? Because the antenna design of each phone a placement angle is not the same, so there will be different wireless performance in a long-distance environment. Unless there is a huge difference in wireless performance between the two, it is difficult to have an overwhelming win on the side of existence. And I’m looking for each other are looking for about the same price.

From the above measured data, the Xiaomi AX6000 has better uplink speed performance.

V. Summary

H3C Magic NX54 official price of $ 90, 512MB memory will be twice as large as XDR5430, do not worry about the memory is not enough, although the output power of the 5G FEM chip compared to the Xiaomi AX6000 with QPF4588 to be lower, but the actual speed difference in the same level of the three positions is not obvious, the obvious difference is in the downstairs D point of 5G uplink speed up.
