Hardware leakers Jaykihn and Harukaze5719 have reportedly leaked the power profiles for Intel’s Arrow Lake and Panther Lake processors. These next-generation chips will rival the best CPUs on the market.
The leak details Intel’s Baseline, Performance, and Extreme power profiles for five different variants of Arrow Lake-S processors. The core configurations and TDPs include: 8+16 at 125W, 8+12 at 125W, 6+8 at 125W, 6+8 at 65W, and 6+4 at 65W. The first number represents the number of P-cores, while the second represents the number of E-cores on the chip.
For the flagship 8+16 125W configuration, there are Intel profiles that motherboard manufacturers can choose from: Baseline, Performance, and Extreme. The Baseline profile offers a PL1 rating of 125W and a PL2 rating of 177W; the IccMAX current limit is 287 amps. Performance offers a PL1 rating of 125W, a PL2 rating of 250W, and an IccMAX current limit of 347 amps. The Extreme profile offers a PL1 rating of 125W, a PL2 rating of 295W, and an IccMAX current limit of 400W. This flagship 8+16 configuration is the only core configuration that offers an Extreme profile.
The 8+12 125W Baseline profile has a PL1 rating of 125W, a PL2 rating of 177W, and an IccMAX limit of 287 amps. The Performance profile maintains the same PL1 rating of 125W, but increases PL2 to 25W and IccMAX to 347 amps.
The 6+8 125W Baseline profile has identical PL1 and PL2 values at 125W, so this profile has only a single power level. IccMax is limited to 203 amps. However, the Performance profile increases PL2 to 159 watts and IccMax to 242 amps.
The 6+8 65W configuration has significantly reduced power limits due to the lower TDP. For the baseline, the PL1 rating is set to 65W and the PL2 rating is set to 84W. IccMAX is set to 143 amps. For the power profile, PL2 is increased to 121W and 188 amps respectively. The least powerful configuration, the 6+4 65W configuration, inherits the same profiles as the 6+8 configuration.
Differences to Raptor Lake
Arrow Lake’s power profile parameters are very different from Raptor Lake’s. Arrow Lake’s flagship 8+16 125W Extreme profile has a significantly lower PL1 rating; Raptor Lake’s equivalent Extreme profile on the 8+16 125W chips uses a 253W limit for PL1 and PL2. The power profile is also different, with Arrow Lake PL2 peaking at 250W and having a 347 amp limit. The power profile on the Raptor Lake equivalent inherits the same 253W PL1 and PL2 configuration from the Extreme profile, but lowers the current limit to 307 amps.
The baseline profile is also slightly different; Raptor Lake has a higher PL2 rating of 188W but a lower current limit of 249 amps.
Similar changes also occur in the 8+12 125W configuration. The power profile for Arrow Lake has a much lower PL1 rating and a higher current limit. Raptor Lake again has identical PL1 and PL2 limits of 253 watts. The baseline profile on Arrow Lake has a slightly lower PL2 rating but a slightly higher IccMax current limit.
Again, there are changes to the 6+8 125W configuration for Arrow Lake and Raptor Lake. The power profile for Raptor Lake again has identical PL1 and PL2 ratings, but this time at 188W. Arrow Lake, on the other hand, has two different limits for PL1 and PL2, with both being below 188W. Arrow Lake also has a much higher IccMax limit, 42 amps higher than Raptor Lake.
The biggest differences in Intel’s power profiles are arguably in the 6+8 and 6+4 65W configurations. Intel made big changes with Arrow Lake by adding a power profile to these 65W configurations. Raptor Lake, on the other hand, has only a single “default” profile. Raptor Lake’s default profile is more similar to Arrow Lake’s power profile, offering a slightly stronger PL2 rating but a lower IccMAX limit. The baseline profiles for these two chip configurations on Arrow Lake are really restrictive, with neither option allowing the chips to consume triple-digit power.
Panther Lake and Mobile Arrow Lake
Another post by Jaykihn showed a huge range of performance profiles for Panther Lake and Arrow Lake Mobile. There is a massive amount of data, so we will only highlight a few of the profiles that caught our eye.
The Panther Lake 6+8+4 (the latter number are Xe GPU cores) chip (PTL-H) reportedly has a PL1 rating of 45W, PL2 80W, PL3 82W, and PL4 240W with an Iccmax rating of 149 amps. The low-power variant (PTL-U) with a 4+0+4 configuration has 15W PL1, 54W PL2, 56W PL3, and 142W PL4 with an IccMax limit of 79 amps.
The most powerful Arrow Lake notebook chip, the 8+16+4 configuration (ARL+HX), has a similar power configuration to its desktop counterparts. PL1 is rated at 55W, PL2 at 160W, PL3 at 162W, PL4 at 291W, and Iccmax at 263 amps.
Jaykihn’s chart also highlights the addition of a low-power Arrow Lake chip with a 15W PL1 rating, revealing that Intel will make low-power Arrow Lake chips even though Lunar Lake is already full.
