what AMD need is to release HX version of laptop chip that come with 3D cache. (8 core version)
Right now they only offer 16 core version, which is super expensive. I dont know why AMD like to sand bagging these days it is not like they got majority market share.
And they got desktop version 7800X3D, these are selling cheaper than HX in laptop. Whats the reason holding back in 3D cache in HX line up?
The same reason the high end dgpus are always forced to be paired with high end CPUs that are overkill for gaming. They’re rather not sell if they can’t upsell a whole combo.
My guess is heat. The 7800x3D only consumes 85W max, but cools like a 120W chip thanks to the extra cache acting as a thermal blanket. The 7940hs has a wattage of between 35 and 55. That’s gonna be hard getting a chip to perform at max under 55W so it can still be cooled like a 55W chip. With the max clock speed hit such a wattage will cause, the 3D cache may not make up for that performance hit.
They should cap it at 28W then, shouldn't lose much if any performance
