Intel 13th Gen Raptor Lake-S Desktop CPU Power Requirements Detailed - Will Come in 125W, 65W & 35W Flavors
The power requirements of Intel'south 13th Gen Raptor Lake-Due south Desktop CPUs have been revealed past Igor Wallossek of Igor's Lab. The information comes just a week afterward we reported the get-go ability numbers of Intel's 12th Gen Alder Lake Desktop CPUs and it looks like Raptor Lake is going to stir upward some changes, although modest ones.
Intel's 13th Gen Raptor Lake & 12th Gen Alder Lake Desktop CPUs Pretty Much Like In Terms of Ability Requirements, Leaked Documents Show
The Intel Raptor Lake-S Desktop CPU lineup volition exist replacing the Alder Lake-Southward Desktop CPU lineup in 2022. The family volition be competing directly against Intel's Raphael processors based on the new Zen 4 cores that will characteristic a 5nm process node and then it's going to be a pretty tough contest in the consumer segment. The lineup volition besides feature a similar division and launch in 125W 'K', 65W 'Standard', and 35W 'Low-TDP' variants.
Equally per Igor, a pocket-size change in the Intel Raptor Lake-South CPUs volition be PL4 limit moving to a Reactive operation. Intel Alder Lake-S CPUs volition feature a Proactive operation but the new Reactive way will allow the chips to hitting higher frequencies on both functioning and efficiency cores optimally. PL4 would nonetheless remain an opportunistic limit with a Tau of <=10ms so information technology will almost e'er evidence up as a fasten during certain workloads. The PL4 limit also triggers the overcurrent protection for the power supply every bit it hits the highest wattage and amperage on the platform itself.
Intel Alder Lake-S & Raptor Lake-Southward Desktop CPU Power Requirements (Paradigm Source: Igor'southward Lab):
Coming to the ability requirements, the Intel Raptor Lake-South 125W variant will feature a PL1 rating of 125W (125W in operation style), PL2 rating of 188W (253W in performance style) & a PL4 rating of 238W (314W in performance manner). Yous can discover that the PL4 rating is lower due to the newly introduced reactive operation but the PL2 rating has gone slightly upwards compared to Intel Alder Lake (253W vs 241W).
The same is the case with the 65W Alder Lake fries which have a PL1 rating of 65W (65W in perf manner), PL2 rating of 133W (219W in perf mode), and a PL4 rating of 179W (277W in perf manner). In the end, we accept the Intel Alder Lake-Southward 35W variants which have a PL1 rating of 35W (35W in perf fashion), PL2 rating of 80W (106W in perf mode), and a PL4 rating of 118W (152W in perf mode).
Intel Raptor Lake Desktop CPUs Ability Ratings
| CPU TDP Segment | 125W | 65W | 35W |
|---|---|---|---|
| Alder Lake PL2 | 188W (241W Perf) | 126W (202W Perf) | 78W (106W Perf) |
| Raptor Lake PL2 | 188W (253W Perf) | 133W (219W Perf) | 80W (106W Perf) |
| Alder Lake PL4 | 283W (359W Perf) | 195W (311W Perf) | 131W (171W Perf) |
| Raptor Lake PL4 | 238W (314W Perf) | 179W (277W Perf) | 118W (152W Perf) |
| Peak Wattage Increase (Alder Lake vs Raptor Lake PL2 Perf) | +five% | +5.5% | +ii.v% |
| Peak Wattage Increment (Alder Lake vs Raptor Lake PL4 Perf) | -19% | -9% | -11% |
So overall, you are looking at a slight increment in the maximum power requirements while the PL2 rating which is the almost operable limit on Intel Desktop CPUs is going down in terms of wattage on 13th Gen Raptor Lake CPUs. The Intel Raptor Lake CPUs are expected to launch in 2022 and will be featuring support on the existing LGA 1700 socket & 600/700-serial platform with DDR5 memory, an increase in core count, and general IPC improvements.
