Chat 2023/02/08 (Does a detuned version of S8Gen2 exist?)

In the previous article, I pointed out that the S8Gen1 and S8+Gen1 are SM8450 and SM8475, respectively, and that they may be completely different. Well, there was a slight performance improvement due to the difference between Samsung and TSMC and the base clock up, but even so, given Qualcomm's model number rules, I think we can't completely rule out the possibility that they are different. Even if Xiaomi or ZTE are equipped with them, it is quite difficult to compare them in their original state, so I think it would be easier for us to judge if they were to use them differently for GALAXY and XPERIA, etc.

The main topic of this article is about reading from the model number of the S8Gen2. The SoC called S8Gen2 for GALAXY has the model number SM8550-AC. The regular version of S8Gen2 has the model number SM8550-AB. It is the so-called relationship between S888 and S888+. However, what bothers me this time is that the SoC that corresponds to the SM8550 has not been announced. Normally, the regular version should be the SM8550, but I wonder why they have bothered to add AB.

So, I thought that there might be a detuned version, like the S820 in the past. The S820 is usually 2.2GHz, but Xiaomi's mi 5 certainly had a 1.8GHz version, so I'm a bit curious as to whether there will be something like the S8Gen2 Lite this time, or whether the prototype will be the SM8550.

As has been pointed out many times, high-end smartphones also have to fight with the cooling mechanism, and it's normal for them to be over 200g. Models that weigh less than 200g have problems such as thermal throttling because the cooling can't keep up, so I think it would be interesting if there was a detuned version, in the sense that it would broaden the range of smartphones that can be equipped with it. For example, XPERIA can differentiate between the 1 series and the 5 series by installing the regular S8Gen2 and the S8Gen2 Lite, and can add value to the regular version.

However, it is also a problem that there will be no economies of scale. In that case, it will be treated as a different SoC, so I think Qualcomm will not accept it. I think XPERIA should try harder not to operate it at full clock, but to deliberately suppress the clock to prevent heat-related problems. I'm going back to the usual topic, but the S865 was excellent in that respect.

The end

This is a story about the series composition based on the SoC model number.
