Discussion Intel current and future Lakes & Rapids thread

I think ARL will still use more power.

Possibly. AMD still has a 230W PPT part. If Intel dials back the PL2 values a bit, they could slide in under that number.

All I care about is power usage and performance. You could have argued that RL was essentially equal, at least in performance, (except for gaming --7800x3D), but that is in flux now because of the stability issues, and what the performance will be with whatever fix is ultimately done. In performance per watt, AMD is clearly ahead.

Unfortunately, the performance does not scale linearly with the power. The performance per watt ratio depends on the selected power level, and, which is more confusing, it does not scale linearly with the load.

For example, the mobile AMD Ryzen 7950HX, while being more efficient than 13900HX on the full load, has a much higher idle power consumption. As a result, the laptops with 7950HX rarely work longer than 4-5 hours compared to 6-9 hours for Intel.

Might be dependent on OEM firmware.

8945HS from Razer is BAD but 7840HS from Lenovo looks good enough. Not as horribly behind Raptor as the Razer laptop so it would seem Razer is doing something wrong.

Finally, Intel might originate the era of silicon photonics.
I think this Intel's breakthrough should be great opportunity for IFS.
IFS can not only provide the integrated photonics solution for intel products, but also NVIDIA/AMD.
