Intel’s 12th-generation Core i ultra-thin laptop chip debuts

Although Intel said that 12th Gen Core i laptop processors announced at CESAt the time, there was a little mention of U-series and P-series chips, but the protagonist at that time was the H-series, so there was not much detailed information. Now Intel has finally officially released the 28W Alder Lake-P and 9W / 15W Alder Lake-U series processors for thin and light laptops and tablets, with detailed models and specifications.

But the first thing to talk about is the change in the model naming rules-after the 10th and 11th generations inexplicably added the “G1 / G5 / G7” suffix representing internal display performance, this generation of Intel has restored the previous naming rules, The approximate TDP and target market are only indicated by “H / P / U” at the end of the model. However, among the 20 chips released today, the i7 has 96 display execution units (EU), the i5 has 80 EUs, and the i3 has 64 EUs, so i7 / i5 / i3 can be used to distinguish the internal display level Is it.

There are six P series processors in total. The highest-end i7-1280P is equipped with 6 high-performance P cores and 8 power-saving E cores (6+8). The basic P core frequency is 1.8GHz, and the highest P core Overclocked up to 4.8GHz. Both i7-1270P and i7-1260P have 4+8 cores, and the difference between the base frequency of the P core (2.2GHz) and the highest overclock (4.8GHz) of the 1270P is 100MHz higher than that of the 1260P. Both i5-1250P and 15-1240P are also 4+8 cores, and both have a base frequency of 1.7GHz P core and a maximum overclock of 4.4GHz. The only difference seems to be the internal display frequency. The former is 1.4GHz, while the latter is 1.3GHz. Finally, the i3-1220P is a 2+8 configuration with a P core base frequency of 1.5GHz and a maximum overclock of 4.4GHz.

U-series processors are divided into seven 15W models and seven 9W models, with a total of 14 models. Although it looks messy, in fact, the difference between 15W and 9W is only in the frequency, and other specifications are the same. For example, the 15W i7-1265U (mantissa is 5) has 2+8 cores, 1.8GHz P core base frequency and 4.8GHz overclock; and 9W i7-1260U (mantissa is 0) also has 2+8 cores , but the base P core frequency is only 1.1GHz, and the overclock is 4.7GHz. The same situation is also applied to the remaining products, i7-1255U / i7-1250U, i5-1245U / i5-1240U, and i5-1235U / i5-1230U are all 2+8 cores, and the frequency decreases in order; i3-1215U / The i3-1210U is 1+4 cores. And further down there are Pentium 8505 / 8500 and Celeron 7305 / 7300 two pairs of 1+4 core low-end products, among which Celeron lost the ability of Turbo Boost overclocking.

Of course, the real key is still how much improvement the 12th-generation Core i has compared to the previous generation, and theRyzen 6000U series released last weekcomparison between. Compared with the 11th generation last year, which was only a small improvement, it is really exciting to see how the laptops with the 12th generation processor P+E core architecture perform!
