Okay this has been bugging me for a while now. It's a bit hard for me to explain it all in English but I'll try to do my best so just bear with me.

 

We all know when the new gen FX came out (8150 and so on) they were a disaster in single-threaded workloads, it has gotten a bit better now but not by much compared to what Intel has against them. AMD got a fair load of criticism for it, still does. (I'm not talking about the fanboys from either side, but the review sites like Toms etc.) Now, since both the new Xbox and PS are using Jaguar (8 core) game developers have much more in hand to start making more of an use of the multi-threaded workflows.

 

Whats my point in all of this is that can it be so AMD was already in talks with Sony and MS about the new consoles before releasing the new FX so they sacrificed single threaded to more of an multicore arch knowing it would pay off later when the new gen consoles are released? I mean mostly as I've seen it's Singlethreaded = Intel, Multithreaded = AMD, but when software will be more dependent on cores later on then AMD MIGHT actually get back in the game again?

 

The TDP is not really a topic right now in all of this. Intel is on a smaller node so it's natural they have lower TDP's. AMD is still on 32nm if I remember correctly?

 

I'm of course talking about the desktop CPU's, don't know much about APU's but since they use the same arch I guess it should also go for those as well.

 

I know this might sound messy as heck but it's the easiest way I can explain my thoughts right now.

AMD was clever to go after the consoles, most of the ports nowadays are more or less optimized for the x86 architecture but nonetheless they still are ports, hence I'm really having my doubts wheter or not fully optimization is made on them. This reflected itself on intel always going on first because they can handle more computational overheat than AMD, this time around however the native implementation is x86 on the AMD side, with this in mind developers will utilize all the resources put in that APU, which certainly translates to a better view on the AMD PC side... I'm curious to see the new games and how their ports compare in both intel and AMD platforms.

I personally think AMD just jumped the gun and went for more cores too early in the game.

 

As for TDP, can't really expect an energy efficient chip which runs at almost 4GHz and with 8 cores.
Just look at Intels new CPU's, finally releasing an 8 core with an even higher TDP (150w compared to 125-130w from AMD).

AMD's latest CPU's have a TDP of 220W.

Which is a limited edition, factory overclocked, non-mass produced CPU for enthusiasts.

its interesting because like ya said theres not much game wise thats optimised for multithreaded / more cores wise mainly cus apparently its not needed. except maybe alot of games are ports from the previous generation of consoles where the cpu's prolly couldnt handle all that much also i dont think the xbox operating system could handle it all that well. Now then if the new xbox OS is based of a custom build of win 8 that opens up alot of possibilities as win 8 handles all that stuff far better than anything before it and its well known gamers choose win8 because of its speed improvements under the hood. you can bash metro and all that crap as much as you want but the basic fact is that it is faster than win 7 and handles multithreaded stuff better, i think it can use unused cores at an OS level by shifting loads onto the unused cores without the app/game telling it to do it, dont qoute me on that cus i might be remembering it wrong. There both getting the jaguar AMD cpu's think there both 8 core, i bet the xbox could manage it far better than the sony simply because MS builds operating systems and the directx API, SDK's everything you can imagine. Sure PS4 has more power on paper but it will prolly end up even tbh optimisation counts for a hell of alot so theres prolly not much in it

No, the FX-9370 is none of those things.

It is, AMD said that it's only available to OEM. FX8350 is the one for consumers.

Steamroller is next architecture promising really great enhancement..

 

Worth reading Anandtech article: http://www.anandtech...er-architecture

 

I think console processors are also based on steamroller architecture cores with GCN 1.1 or 2 based GPU cores. It will be hell of a combinations. So lets hope that on desktop market, AMD brings at least some competition for Intel future gen processors.

 

AMD next node will be 28 nm or whatever TSMC or Global Foundries decides.

For Intel next node is 14 nm.

CPUs are all about single-threaded performance and will remain this way. We're not headed towards CPUs with more cores, but rather heterogenous systems combining a processor that excels at serial workloads (i.e. the "CPU") and one that excels at parallel workloads (i.e. the "GPU"), both sharing the same memory and sometimes even on the same die (i.e. Trinity -> Kaveri).  This is the design used in the next-gen consoles; on PC we're slowly heading there (I guess?) with recent advances like compute shaders, gpu computing frameworks like CUDA, OpenCL, AMP, etc.

 

For the past several years Intel has done plain better than AMD in the desktop CPU space; AMD has attempted to compensate for its poor architectural performance by throwing more cores and higher frequencies at the problem, with lackluster results. However as Carmack noted during his last 2-hours speech, AMD dictating the architecture on next-gen consoles should give it an edge as all engine code will be optimized for AMD first.

AMD's HSA is where it's at.

this wont somehow give AMD an edge in the future in the computing space at all. Theres one reason,and one reason only why Sony and Microsoft went with the jaguar chip. PRICE. You have to remember jaguar is an architecture for mobile type devices. It has low power consumption,and its way cheaper than putting a beast like a core or piledriver/(steamroller?) chip in there. The consequences of this is that developers are going to have to multithread up the ass to get good performance out of these console chips.  We've also heard 3rd party developers accounts on how next gen console games are written for PC first(singlethreaded,cough), then dirty compiled to consoles, then optimized,likely by doing some heavy multithreading. I bet the custom GPUs are also going to be used to offload computations to give the cpu some breathing room,and don't forget the Cloud ;)

Jaguar isn't an architechture, it's the name for AMD's APU offerings built on Steamroller.

 

So basically, 4 Steamroller modules and one on-die GPU.

jaguar is a microarchitecture. its an improvement over the bobcat microarchitecture. jaguar chips use jaguar cores,not steamroller cores. steamroller is a microarchitecture itself. it is an improvement over the piledriver microarchitecture. There are APUs using Jaguar, and there are APUs using Piledriver,and there will be APUs using Steamroller. Low cost Notebook APUs like the A6-5200 are using jaguar cores, because guess what, these are low power devices, while desktop APUs like a10-5800k are using piledriver cores because these are performance devices that dont need to be low power. xbox one and ps4 are using jaguar cores in their APU,not piledriver,not steamroller.

 

bobcat->jaguar low power microarchitecture

 

bulldozer->piledriver->steamroller performance microarchitecture

Steamroller is the successor to Piledriver, Jaguar is the successor to Bobcat. Different architectures, different target platforms. The APUs built on Steamroller will be called Kaveri.
