Last year, AMD introduced the new AM4 series motherboards. For the first time, the original USB 3.1 Gen2 interface was added to the motherboard chipset. This year, Intel introduced the new motherboard chipset H370/B360 with the native USB 3.1 Gen2 interface. The USB 3.1 Gen2 interface has finally come to our consumers.
The USB 3.1 Gen2 interface has a theoretical bandwidth of 10 Gbps, and the theoretical transmission speed should be 1000 MB//s. Compared with the theoretical bandwidth of only 5 Gbps, the USB 3.1 Gen1 interface has made great progress. But the USB 3.1 Gen2 interface on our motherboard has been Provided by a third-party chip maker such as Xiangshuo, if you need to use another driver, it is very inconvenient. More importantly, this is very unfriendly to Xiaobai. After all, many whites may not download the driver, resulting in This interface is wasted.
Until now, the mainstream motherboard chipset has a native USB 3.1 Gen2 interface that enables the use of lighting. So will the AMD motherboard chipset's native USB 3.1 Gen2 and Intel chipset be different? Let's take a look today..
In order to ensure the objectivity of the evaluation, both of our motherboards use the same brand of MSI products. We picked up an AMD chipset motherboard and an Intel chipset motherboard in the MSI motherboard.
AMD uses the MSI B350M MORTAR mortar board. AMD has outsourced the motherboard chipset from the AM4 motherboard to the ASUS subsidiary Cheung Shuo Design. Cheung Shuo was established in 2004 and has a long history. History, the main business is a variety of high-speed master chip, including USB, SATA, PCI-E, etc., a large number of motherboards can see his product, so the native USB 3.1 Gen2 interface on the AM4 motherboard is naturally also adopted Master plan.
This is Xiaobian's search for the B360 motherboard from the evaluation room for a long time to find MSI, MSI (MSI) B360M MORTAR TITANIUM mortar titanium version is a MATX motherboard, using 7-phase power supply, full of materials.
The chipset is the B360 chipset and one of the first Intel chipsets with a native USB 3.1 Gen2 interface. The Intel motherboard chipset is designed by Intel itself, so the native USB 3.1 Gen2 interface used on the B360 motherboard chipset is undoubtedly Intel. Their own plan.
testing platform
In addition to the motherboard and processor, we try to keep the other accessories consistent.
We need to use the transmission speed to break the bandwidth limit of the USB 3.1 Gen2 interface to test the difference of the native interface of different chipsets, so we can only use the external SSD hard disk box that supports the NVMe protocol to install the NVMe SSD with the theoretical transmission speed bandwidth up to 32Gbps. carry out testing.
The external hard disk box uses the i9, which ranks one of the top sales in Taobao. Jiayi Technology is a company with a large number of mobile hard disk boxes. Here we use its latest NVMe hard disk box i9. China Red is the main color scheme, which is more eye-catching. Is its performance as good as the appearance of Zhang Yang? You have to try it.
It uses JMicron's JMS583 chip, which is a USB 3.1 Gen 2 to PCIe 3.0 x2 bridge chip, and also supports SSD TRIM instructions, supporting a maximum transmission bandwidth of 16Gbps, much higher than the USB 3.1 Gen2 interface 10Gbps Bandwidth, so don't worry about not being able to test the difference between AMD and Intel platforms because of insufficient transmission bandwidth.
The NVMe SSD we use here is Samsung's 960 PRO. This SSD guarantees that we have enough transmission speed in the test, and will not overheat and slow down. After all, it is the Samsung flagship SSD.
Verification Test
The easiest way to verify the difference in transmission speed is to use the test software. Let's take a look at the differences between the two platforms in the AS SSD test software. Note that the following tests are all based on the Type C interface of the motherboard.
Intel platform
AMD platform
Test summary: In AS SSD test, Intel's continuous read and write performance will be slightly higher than AMD platform, and AMD platform's random read and write performance will be slightly stronger, subdivided Intel platform will be better in writing performance, and AMD platform read performance. It will be a little better, but in general the two platforms are not much different.
Let's take a look at another commonly used SSD test software. Crystal Disk Mark 6The performance of the two platforms.
Intel platform
AMD platform
Test summary: The test results are basically consistent with the above test. The random read/write and read performance AMD platform will be slightly stronger, and the write performance of the Intel platform will be stronger. In general, the difference between the two is small.
Repeated literacy test - result unexpected
In order to make the results as objective as possible, Xiaobian I connected the motherboard's Type A interface for testing, but the result was unexpected.
After connecting the Type A interface of the motherboard, the computer often does not sense the external SSD, let alone run the test.
The only time I finished the test was very low. And this situation will appear in both the AMD chipset and the Intel chipset, and even the colorful B360 motherboard, which preliminarily eliminates the problem of the motherboard and the motherboard chipset..
Is it a problem with SSD? Then I switched to Toshiba RC100 SSD for testing. Of course, there is no accident that there is a problem that cannot be identified. It can be judged that the compatibility of the Jiayi i9 mobile hard disk box is not small.
Is the hard disk box broken? Xiaobian I connected the Type C interface of the motherboard, the identification is very easy to identify, As a result, there was a problem of a large speed drop in the read test.
Try it, Found that the speed has reached a terrible point In desperation, Xiaobian had to give up the intention to continue testing.
to sum up
For the speed difference between the Intel motherboard chipset and the AMD motherboard chipset native USB 3.1 Gen2 interface, the above test has been presented clearly. In general, Intel write performance will be slightly stronger, AMD read performance and Random literacy will be better, but in fact the difference between the two is not large, will not significantly affect the user experience.
With the increasing popularity of high-speed USB interfaces, NVMe's mobile hard disk box is also useful, but everyone should be cautious when purchasing NVMe mobile hard disk boxes, although this hard disk box is more affordable, but like Xiaobian That took 200 oceans to buy such a mobile hard disk box, After testing for a day, there were various problems that could not be used at all. , I made a big loss.
