amd fx-8800p in a desktop formfactor.

You sure that is not a misprint? It also says 8 cores.

I guess it could mean 4 cpu and 4 gpu cores. If it is Carizzo though, seems way too expensive.

good question. Note that carrizo has 8 GCN clusters, so that also doesn't seem to be it.

I hate the dearth of technical specs from Best Buy these days. It also doesnt mention any discrete gpu, so that makes it even more confusing.

I'd imagine be the less technically inclined would feel the same way with the specs info that we would require.

Well, mostly. The main other complaint I see is that they're only 15W and not 35W, but AMD has been pushing the chips as low power chips, that's what they mainly talk about in their presentations. So why would you need Intel to explain that OEM's are using this configuration?

Another fun fact: Carrizo defaults to DDR3-1600 speeds when cTDP limited to 15W, no matter what the capabilities of the SODIMMs.

Carrizo was sold as having an adjustable cTDP which the OEMs basically refuse to use (in most cases). Carrizo is also being sold on the merit of being board-compatible with Carrizo-L (which is just Mullins with a new paint job). OEMs are responding by selling most Carrizo laptops with hardware configurations designed primarily for Carrizo-L.

Point being, Carrizo is supposed to be able to swing between cTDP points according to user selection or even dynamically (I think). OEMs are locking it at 15W cTDP, which is really only meant for slim form factors or light duty computing, or maybe ultra-long battery life at the user's discretion.

Why go to Intel? Simple. OEM stupidity/sloth is improbable, since they have no problem configuring laptops for Intel (outside of the battery), and Intel has used anti-competitive practices before to keep AMD chips out of the OEM space (well, anti-competitive by EU standards anyway).

And again, battery life is a bigger selling point than computing power and the Intel configurations of these laptops also have 15W versions.

As I mentioned above, I think many laptops in this segment are getting short shrift on battery size which is hurting both camps;

Really, I haven't seen anything that can't be explained by actual logic (i.e., OEM's making choices based on their understanding of the market), and though I did call this 'stupidity', that simply because what sells well (or OEM's think sells well) isn't necessarily what takes full advantage of the technology. (Although if AMD is to be believed, running the chips at low power is precisely what takes full advantage of the work it's done.)

Then why are they even producing AMD products at all? They don't need AMD products in their lineup if all they're going to cripple them needlessly.

If AMD's intention was to run the 8700P in 15W mode permanently without any user option to adjust that figure up to at least 25W, then they are criminally insane. I do not think that was ever their intention.

I'm sorry but if you think a secret conspiracy between Intel and OEM is in line with Occam's razer, you're completely misapplying it.

If we accept Occam's Razer, that the simplier answer is the better answer, we can conclude that OEMs don't prioritize AMD laptops because consumers don't prioritize AMD laptops.

Your explanation introduced a third party, Intel, needlessly.

Intel's past behavior is hardly a secret. Also, remember that the Razer only applies to "competing hypotheses". I conclude that the hypothesis that "OEMs don't prioritize AMD laptops because consumers don't prioritize AMD laptops" must be discarded on that ground that nobody would ever have to "prioritize" AMD laptops in order to, you know, throw in an extra fan or two to accommodate a user-selectable (or dynamically-selectable) cTDP of 25-35W. Instead they include redundant and more-expensive-than-some-dinky-laptop-fan dGPUs in the laptops that often share the same heatpipe system as used by the CPU! Dual graphics? Eh okay. In any case, difference in priorities hardly explains the configuration problems. But hey, draw your own conclusions.

Since Carrizo is out now and the situation is evolving (as monstercameron pointed out), maybe we should move some of this conversation to a new thread? It's not pre-release time for Carrizo anymore.

Also, the Dell model in question appears to be the Inspiron 3656:

http://www.dell.com/us/p/inspiron-3656-desktop/pd?oc=ddccz303hw10&l=en

It indeed has an FX-8800P. It has an R9 360 and is listed as a "gamer edition". Interesting. You would think a 7870k would do better here, but leave it to the OEMs to use a mobile chip in the desktop form factor where a desktop chip belongs. There are also 8700P desktop configurations.

now they advertise ddr4 and to the embedded crowd, who probably don't care. sigh...

DDR-3 2133MHz 1.65V

DDR-4 2400MHz 1.2V

DDR-4 = lower power, lower thermals, higher bandwidth

 

[mikk]

DDR-3 2133MHz 1.65V

1.5V

 

[AtenRa]

1.5V

Not for 2133MHz

 

[railven]

Not for 2133MHz

RAM I use is 1.5v 2133mhz. Unless Corsair is practicing false advertising.

 

[mikk]

Not for 2133MHz

Even for DDR3-2133.

First embedded processor with dual-channel 64-bit DDR4 or DDR3 with Error-Correction Code (ECC), with speeds up to DDR4-2400 and DDR3-2133, and support for 1.2V DDR4 and 1.5V/1.35V DDR3

[monstercameron]

I'm confident that carrizo's mc could handle 1.65V ddr3 like kaveri.

 

[AtenRa]

Heh ok i was thinking of 2400MHz, my bad

Yes there are new models at 2133MHz and 1.5v

My guess is that they sell AMD laptops because AMD begs really hard, and OEM's don't mind risking a little bit on the off chance that AMD will come back in some way. But that's why they see no reason to invest much.

Edit: Well, it's probably more like this: OEM's come to AMD and say 'there's nothing particularly attractive in your CPU's.' AMD asks: 'How can we make them more attractive?' OEM's say: 'Low power sells well these days, we expect that market to grow, and your CPU's for this segment are too slow.' So AMD goes to create a low power APU and brings it to the OEM's, who say: 'oh, well, I guess we asked for it, so we'll try to put it into something, see how it goes.'

Did anybody already spot a Merlin Falcon retail board somewhere?

This thread started in October 2014 and finally November 2015 we might be able to buy this CPU for a desktop. Amazingly fast progress.

These are not for retail usage. But embedded/industrial. So its unlikely you ever see one.

I will jump to the first 14" 768p FX8800P iGPU ONLY, 2x 4GB 2133MHz i will find.

keep dreamin, oems like to give us what we don't want as long as amd is concerned. It's like it's done on purpose since trinity

At least Trinity has the un38 Asus.

There are a few boards out there but not for retail. Most are embedded or industrial.

Anyone know if the Dell 8800p desktops also limit to low tdp?

 

[jime1]

Still its "Pre-release" !!!

can you link me to one?
