All essential data are sorted in a table. The text serves primarily as a guide to reading the table: The first column contains a specific processor series (bold news, bold current series for comparison). The second column shows the configuration: number of large cores + number of small cores (Atoms) + number of EU (graphics core blocks). The third column shows the TDP of the given model series. The fourth column, the value of PL2, indicates the value that the processor can use until the heatsink is heated (the time limit is usually 28 seconds, 56 seconds, etc.). Although the word “limit” is used in connection with the abbreviation PL2, PL2 is not in fact a limit value, but a value that can be exceeded, albeit usually only for a short time. The real limit that should not be exceeded is the value of PL4:
| advice | nuclei + atoms + EU | TDP | PL2 | PL4 |
|---|---|---|---|---|
| Tiger Lake-M | 2 + 0 + 96 4 + 0 + 96 |
9W | 35W 40W |
66W 83W |
| Alder Lake-M | 2 + 8 + 96 | 9W | 30W | 68W |
| Alder Lake-P | 2 + 8 + 96 | 15W | 55W | 123W |
| Tiger Lake-U | 2 + 0 + 96 4 + 0 + 96 |
28W | 38W 60W |
71W 105W |
| Alder Lake-P | 4 + 8 + 96 | 28W | 64W | 140W |
| Tiger Lake-H | 8 + 0 + 32 | 45W | 107-135W | – |
| Alder Lake-P | 6 + 8 + 96 | 45W | 115W | 215W |
In the case of 9W models, it is clear that Intel s Alder Lake-M dropped the configuration with four large nuclei and will remain with only two large nuclei and up to eight atoms.
15W Alder Lake-P with two large cores it will have a PL2 (55W) higher than a dual core 28W Tiger Lake (38W). The 123W PL4 limit of this 15W model is also worth attention.
The 28W Alder Lake-P series then slightly increases the PL2 (60-> 64W) and significantly increases the PL4 limit from 105 to 140 watts. There is no comparison for the 45W series, as PL2 could be set in range and PL4 was not defined in the default recommended configuration. However, the 45W Alder Lake-P should not exceed 215 watts for even a short time.
From these values and so far leaked information about Alder Lake it seems to be an architecture capable of achieving very high IPCs and very high frequencies, but the performance achieved in this way is strongly due to energy efficiency and energy requirements. The whole situation is that Intel has the means to outperform AMD and does not intend to significantly reduce them in any way by energy limits. This winter will be warm.
