Intel Arrow Lake & Panther Lake Power Ratings Revealed: Top Desktop SKU Has 295W PL2, Canceled 40-Core Die Had 352W PL2 & 667W PL4 TDP

Power ratings of Intel's next-generation Arrow Lake & Panther Lake CPUs for desktop and laptops have been revealed by Jaykihn.

Intel's Arrow Lake CPUs will be covering various segments ranging from desktops to laptops. Both families will have a diverse range of SKUs & each configuration will yield its respective power rating depending on the platform it is designed for. So far, we have learned about the die configurations, the cache configurations, and the clock speed configurations on a range of Arrow Lake chips but a huge list of Arrow Lake configurations along with their full power ratings has been disclosed today by Jaykihn.

Based on the details, we first have the Intel Arrow Lake-S Desktop CPUs which come in 8+16, 8+12, 6+8, and 6+4 SKUs. These are the four confirmed configurations that we will see in the lineup. As of right now, all configurations except the 6+4 will feature up to 125W SKUs in the "K" series & 65W / 35W chips will be standard across all four SKUs. The flagship 8+16 SKU, the Core Ultra 9 285K, is reportedly going to feature an "Extreme" mode besides its "Performance" and "Baseline" modes.

At the Baseline, the top SKU will have a 125W PL1 and 179W PL2 rating, at Performance, the same SKU will have a 125 PL1 and 250W PL2 rating while at Extreme, the SKU will have a 125W PL1 and 295W PL2 rating. The PL4 rating scales from 329/425/490W but this is a short burst mode. Actual power consumption of the chips is suggested to be at least 100W lower than Raptor Lake CPUs.

Besides the known Arrow Lake-S Desktop CPUs, there are at least three unknown & two canceled models mentioned too. The canceled models include 8+32 & 8+24 configurations which were rated at up to 150W PL1 and 352W PL2 ratings with up to 667W PL4 limits under the Extreme profile. The 8+16 150W SKU is also mentioned which has a PL2 rating of up to 295W and a PL4 rating of up to 490 Watts. This SKU is probably going to be reserved for a future "KS" variant.

Intel Arrow Lake-S Die Configurations:

Interestingly, Intel had 8+32 and 8+24 SKUs in the plans. They simply increased the E-Core count which would've yielded higher multi-threaded performance but would've been a pain in terms of scheduling and it looks like the better approach would've been to increase the P-Core counts too.

Besides these higher-end variants, there are two entry-level 4+4 models listed too which could be a future Core Ultra 3 variant though those aren't confirmed for the Arrow Lake-S family. Following is the full list of Arrow Lake-S Desktop CPU models along with their power ratings:

Intel Arrow Lake mobility chips will come in three categories, HX for enthusiast laptops, H for mainstream/high-end gaming laptops, and U for low-power laptops. Arrow Lake-U will be positioned similarly to the Lunar Lake parts though Lunar Lake might end up being a tad bit faster due to its optimizations and innovations that include a focused architectural design along with new Xe2 GPU cores.

Arrow Lake-HX will feature the same core configurations as the main desktop dies. The Arrow Lake-H and Arrow Lake-U CPU configurations don't mention the LP-E core counts as we know that these chips will employ three different architectures, Lion Cove P-Cores, Skymont E-Cores, and Crestmont LP-E cores. Though those LP-E cores sit on a different tile altogether while these configs are only for the compute and graphics tiles.

Following the mobile Arrow Lake launches which will mostly take place in early 2025, Intel will roll out its Panther Lake CPUs by the end of 2025. These chips have also been mentioned with three flavors that include two 6+8 Panther Lake-H configurations and a single 4+0 Panther Lake-U config. These chips scale from 15W up to 28W & 45W. The chips would feature up to 12 Xe cores based on the Xe3 "Celestial" graphics architecture as previously detailed. The leaker also states that while the listed configuration for Panther Lake is 6+8, the retail release will feature a 4+8 configuration.

Following are the TDP ratings for the Panther Lake parts:

Other information suggests that Intel also has a new feature in development for its Panther Lake and Arrow Lake laptop CPUs which will allow the chips to have a different power profile when they are running alongside a discrete GPU. With Lunar Lake all set for a 3rd September launch, we will soon see Intel start talking a bit more about Arrow Lake and the follow-up.
