You misunderstood what I said.
The 7945hx and 9955hx are physically chips that were designed for desktop but repurposed into a laptop form factor.
Physically those are the same chip as the 7950x and the 9950x respectively. They were designed for desktops. They’re just called 7945hx and 9955hx when they’re soldered and put into a laptop.
Putting them into a laptop doesn’t change the fact that physically they were engineered for desktop and putting them in a laptop results in crippled performance and reduced features compared to using a CPU that was designed to offer what laptops need.
There hasn’t yet been much testing of the 9955hx, however the 7945hx lost a lot of performance (~24%) when limited to 55W instead of higher.
And 55W is higher power than what the Framework Laptop 16 is currently rated for (although I do think that it does have some headroom past that 55w). 75w would be a challenge to cool.
There was a leak that that chip is HP-exclusive. There hasn’t been official confirmation of that afaik, however it has only been offered in HP laptops so far and AMD didn’t announce it at a major event like they did all of the other Ryzen AI CPUs.
Although it is almost the same as the Ryzen AI 9 HX 370. The only difference is that the HX 375 has 10% higher NPU clockspeed (which I assume you don’t care about given that you mentioned the 7945hx and 9955hx, both of which don’t have an NPU).
Lately they’ve been innovating at the higher price points, however at low and medium price points they seem to be doing the opposite currently.
For example the Ryzen AI 7 350 is intended as the successor to the Ryzen 7 7840u. The Ryzen 7 7840u has 8 full-sized cores and 12 iGPU compute units. The Ryzen AI 7 350 on the other hand has 4 full-sized cores, 4 compact cores, and 8 iGPU compute units. It does of course have a newer architecture, however it seems to only match the 7840u (its 2 year old predecessor) in CPU performance and fall behind in iGPU performance.
The Ryzen 5 340 vs 7640u is a similar debate.
Only at the Ryzen 9 and above level are they currently innovating.
