Intel officially released the tenth generation desktop core processor codenamed Comet Lake-S at the end of last month. There are a total of 32 models from the top Core i9 to the entry-level Celeron, but I did not expect to secretly dig a hole, the i5 series also To "draw".

According to the latest findings, there are two different stepping versions of the tenth-generation Core i5, one is Q0 and the other is G1.

The Q0 version is based on a complete 10-core chip (an area of about 200 square millimeters), shielding four of them, using new thin chip manufacturing technology, reducing the thickness, leaving more space for the heat dissipation material, and using advanced soldering Welding heat dissipation, temperature, overclocking performance is better.

The G1 version is a native 6-core chip, which is almost exactly the same as the previous 9th-generation 6-core chip. There is no thin chip, and the heat dissipation material is also ordinary silicone grease.

There are two distinguishing methods for the two stepping versions. One is to look at the distribution of components such as capacitors at the bottom of the processor. The Q0 version is obviously divided into two areas.

But on the retail box, you can only see the front of the processor without opening it, so this method will not work, and the second trick is used.

This second method is to look at the S-Spec number, the five letters + numbers printed on the front of the processor, generally three letters, one number, one letter or a combination of numbers, located in the lower row of the product model, followed immediately behind Nominal frequency.

However, there are six models of the tenth-generation Core i5, and the stepping version is divided into three cases:

Both the i5-10600K and i5-10600KF overclockable versions have only a more advanced Q0 stepping. The S-Spec numbers are SRH6R and SRH6S, which can be purchased with confidence.

Both i5-10500 and i5-10600 only have G1 stepping, the numbers are SRH3A and SRH37, so you do n’t have to worry about buying them.

The i5-10400 and i5-10400F are complicated, and there are two types of steps. The Q0 step numbers are SRH79 and SRH78, and the G1 step numbers are SRH3D and SRH3C. Which one you buy may depend on luck. Especially when shopping online.

Of course, the performance of the two steps will not be significantly different in theory, mainly due to heat and temperature.
