Xiaomi Book S 12.4 Might Use Both Snapdragon 8cx Gen1 / Gen2

Xiaomi Book S

We heard the first news about the upcoming Xiaomi Book S just a few days ago. But with every day, we learn more about the new Xiaomi laptop. Many might think there is nothing odd or surprising with such news because Xiaomi has been making notebooks for a while. This brand has already found its place under the sun. And it’s quite logical that the China-based first-tier tech company will periodically update its notebooks line. But the thing is that we are not talking about a regular laptop. The Xiaomi Book S 12.4 will sport a Qualcomm chip.

Xiaomi Book S 12.4 Processors

As early as March, we saw the laptop spotted in GeekBench. According to the screenshot from the benchmark platform, we could see that the Xiaomi Book S 12.4 will come with the Qualcomm Snapdragon 8cx Gen2 chip. As for now, the same laptop has appeared on GeekBench with another chip from this range, the Snapdragon 8cx (Gen1).

We have both screenshots. So we can do any comparison in order to understand how the laptop performs on different generations of the same chip. What’s interesting, there is no substantial difference in the running scores.

As Xiaomi is already testing the Xiaomi Book S 12.4 with two generations of chips of Snapdragon 8cx, there is every reason to think we can see the third model in work as well. We mean recently, Qualcomm launched the Snapdragon 8cx Gen3.

Gizchina News of the week

Qualcomm Snapdragon 8cx Gen3

In terms of parameters, the Snapdragon 8cx Gen3 uses a 5nm process node. Qualcomm said this chip is the first 5nm chip to support the Windows platform. The CPU has four 3.0GHz large cores and four 2.4GHz small cores, with a total of up to 14MB cache and a TDP of about 15W. In terms of performance, compared with the second-generation Snapdragon 8cx Gen 2, the Snapdragon 8cx Gen 3 has an 85% increase in CPU performance, a 60% increase in GPU performance, and a 40% increase in single-threaded performance. In addition, Qualcomm said that this product has 60% higher performance per watt than comparable chips on the x86 platform.

Snapdragon 8cx

We think if Xiaomi really wants to make an Arm notebook, it should eventually choose to carry the Snapdragon 8cx Gen3. Moreover, there are a few brands that have already released their own models sporting the latest chips from this category. The best example is the Lenovo ThinkPad X13s. Also, Microsoft is already preparing its own laptop, which will hit the stores soon.
