Would it be possible for vendors to make a Carrizo laptop thats in 35W mode while plugged in and switches to 15W mode when on battery only? That would be a nice feature in my opinion.

can you link me to one?

The $450 version comes with A8-8600P.

Yikes. Why so expensive?

 

[frozentundra123456]

Yea, those are outrageous prices. You can get a Dell XPS with a 4790 for less than that.

probably it is too low volume?

I think that would be a good idea.

The main issue would be cooling.

That can and is done with software a lot of the time. I've seen that all that way back in the Pentium IIIm days (600mhz/500mhz or 850mhz/700mhz). Now, it's obviously dynamically clocked a lot better so they can and do optionally put upper limits on CPU performance when on battery. All fully adjustable.

Looking at this graph of Excavator (high density library, AVFS) I wonder if they could even have a 5W Carrizo that could transform into a 15W Carrizo when docked:

I doubt you'll have a good experience with 5W carrizo even in a tablet context.

Looking at how that graph scales down to ~2.25W per module, I do wonder if they are considering it though.

Going by a very rough estimate, my guess is that at 2.25W module would have 62% of the frequency of a 7.5W module.

 

[cbn]

I know hindsight is 20/20, but judging how we are not seeing 35W Carrizo being used in laptops and instead we see either 15W Carrizo or 15W Carrizo + 15W dGPU I have to wonder if a 3M Carrizo with a smaller iGPU would have been a better choice?

I mean if OEMs insist on 15W Carrizo or 15W Carrizo + 15W dGPU what is the point of making the iGPU 512sp.

There s more than the modules to feed, MC, FCH, and so on.

AMD themselves said that although doable it s not adequate for 6W TDP, the lowest programable TDP is 12W, and that s only on the A8-8600P, the 8700P and 8800P are 15W mini.

Yea, it seems like a decent product, very poorly implemented. I still dont get why they put that in a full size desktop. I could see it in a nuc, steambox, or SFF case, but for the price of those cameron linked, you could get an intel i5 or full on 7850k APU for a full size desktop.

It's nothing but notebook hardware stuck in a desktop chassis. They're charging a premium for low power usage and large HDD + RAM. Kind of silly, though, since the mobile-oriented motherboard + cooling solution may throttle just like a notebook. Hard to know for sure.

I would buy it just to test but i just crashed my car...

Glad to know you're OK, though! Cars can be replaced...lives cannot!

I'm sorry that happened!!

I'm glad you are still with us.

 

[frozentundra123456]

Agreed.

Sorry to hear that. I would make a joke about an AMD / Intel-based self-driving car, but... nah. Hope you're OK!

Next time buy the laptop before you crash the car

Glad your are ok

Apparently AMD s current mobile offering is in the mainstream segment, the craptops segment seems definitly owned by Intel "thanks" to huge inventories of Baytrails mainly..
