We have had several requests for a sticky on AMD's yet to be released Piledriver architecture ... so here it is.

I want to make a few things clear though.

Post a question relevant to the topic, or information about the topic, or it will be deleted.

Post any negative personal comments about another user ... and they will be deleted.

Post flame baiting comments about the blue, red and green team and they will be deleted.

Enjoy ...

And is this now still expected to be the case?

Is it likely that AMD will bring out a CPU with an IGP for AM3+, or will that only happen on some future platform like an FM3?

I'm sure they'll keep the pin count and make a re-route keeping the same technologies around (DDR3, HT3.1, PCIe 2.0, etc). Like reducing the number of PCIe channels and route Video stuff through it. Or just use some point to point through PCIe to output video for SR.

I don't like them using the same exact socket though, since it will lead to confusion if they actually support more CPU types with a new chipset (since they'll need a new one anyway).

Also, DDR4 is already here, so it seems more risky to not use it right away.

Cheers!

PS: California sure is hot... Ugh.

ddr4 cant compete with ddr3 for atleast 3 years in price. These days the PC sales are slowing. The craze during DDR2--> DDR3 transition is not there.
Besides, chips are "fast enough" for most general tasks. So the average Joe is not buying a new PC.

Kind of sad that PC sales are slowing, but I sigh everytime someone says that tablets and phones will be the doom of desktops and laptops. Most people might be fine with a tablet, but soon they'll realize that for real work, laptops and desktops rule. [/rant]

But yes, DDR3 is not the main bottleneck in a PC. DDR3 is plenty fast and cheap. No one wants to pay DDR2 prices for DDR4.

with out a doubt DDR3 is holding APU's back!

really? how? intel can get nearly 25 gb/s with their imc(sb/ivb)

while amd gets 14 gb/s with theirs(trinity).

at present, amd won't be able to take advantage of ddr4, they can't even max out ddr3.
btw, i think existing lack of pcie 3.0 support in pd and possibly future sr server cpus will hurt them more than in desktop platforms.

I must be honest I was rather surprised at the news about retaining AM3+, many that I worked with were expecting a new socket with modern feature support. While its kind of disappointing I have also heard stories of a new 99X chipset release something like 991FX which will feature higher RAM speeds, PCI-e 3.0, more SATA and for Kaviri based APU's will retain Lucid MVP support. As to the main parts I have heard a hybrid HD 77XX iGPU which does make sense for AMD to persist with it to handle certain FPU calculations.

The problem AMD have right now with APU's is to integrate higher end RADEONS and put intel out of the market completely requires sorting out IPC and bandwidth issues, which while I am not going to say if this is the case with PD but suffice to say progress is being made with the architecture to a point where Steamroller, if not then Excavator will basically be the chip AMD envisaged when they decided to dedicate to heterogeneous and cloud computing.

Having spoken to people involved in AMD the company is now (albeit shares may not suggest it just yet) is in a much better financial and engineering level than it was say 12-18 months ago, there are plans on better FAB process manufacturers, and basically the new regime rolled through BD being under prepared, made what they could with PD, but have focused heavily on SR.

Now the burning question, will AMD ever beat intel on pure CPU performance. It is difficult to say, BD showed that it can be possible in certain instances but to be honest the vibe that I get and this has been construed as "AMD pulling out of DT manufacture" is that AMD are not fighting intel on pure performance, but trying to out maneouver intel, how do they do this.......AMD fusion vision, it has begun to worry intel. What I say is AMD have the advantage going forward, they are closer to HSA, cloud computing and the works, but they can not afford to relax and allow intel to catch up, this is the sentiment shared by many, this is the chance.

PC sales are only slowing in the west, emerging markets like china and india have
huge demand for PCs. Which just so happen to be where AMD hopes to sell a lot of
the APUs.

every fm1 board is out of stock for weeks
thus hard to recommend a apu in India due to less availability 🙁

with out a doubt DDR3 is holding APU's back!

and if they can introduce quad channel ddr4
that will be over 100GB/s of bandwidth 😍

sr on am3+
means no ddr4 for sr

^^ that's kinda strange. i read that amd ended up with oversupply of apus because they couldn't sell enough apus in the emerging markets like india and china. and when they finally increased supply, people witheld buying because of windows 8 release and "soft economy" or something....

only 1 fm1 board and that too costs a lot (for a htpc build)

price list www​.costtocost.in/list/pricelist.pdf
only 1 fm1 board 'GIGABYTE A-55M DS2' is available

while boards of other sockets are easily available with different features/vendors

though apu's are easily available but their boards are rarely (very few options)

and these are popular dealers/shops of nehru place

speaking of motherboards, this does not look good at all.

http://www.tomshardware.com/news/intel-haswell-cpu-soc-motherboard-manufacturers,17959.html

If Intel destroys the motherboard makers, especially starting with broadwell, they in turn destroy AMD along with them since there will be no motherboards except from Intel.

Intel's monopoly is still being played. First Nvidia, now the rest, and AMD falls due to a side-effect.

Lets hope at least one or two makers survive for AMD and the rest of the DT computing industry's sake.

^^ DUN DUN DUN DUN!!!.... :sol:
cue 'ride of the [strike]haswell[/strike] valkyries' theme... :pt1cable:
that aside, how are intel going to destroy motherboards? in desktop platform, low end motherboard brands will suffer a bit (looking at ya, jetway, ecs and biostar et al). even they are trying to improve themselves. mainstream motherboard brands are very likely to remain 'unscathed' from the 'destruction'.
worst case scenario: motherboards become segmented into two main branches - one that just acts as a platform for expansion slots and ports, another that caters to overclockers and enthusiasts. wait, that is already happening...
this could be just as bad if not worse -

...since intel isn't doing the merger, i guess it's less evil and more innovation-friendly.... 😉

PCIe 2.0 had more than double the bandwidth needed for a 580. Even this generation doesn't come AT ALL close to being limited by 2.0, It will be another 2-3 generations before it becomes an issue, imo.



Correction: Steamy on 990FX means no DDR4. You can have a new chipset without changing socket. Intel only just did it a few months ago.

IMO, PCI#3.0 is more useful in servers, where it gives more bandwidth for the several HDD's and SSD's. Plus, the PCIE SSD's are high bandwidth consumers OM NOM NOM....




someone said DDR3 is holding APU's back..... NO.
The AMD IMC is crap. This is 2012, not 1995, where faster RAM means better FPS.....

Tablets and phones dont come anywhere near $800 laptops in terms of performance. Those same laptops hardly compare to $800 home built desktops in terms of performance. I am getting so sick of friends who try to tell me how awesome their mobile gtx 570 or something similar in a $1800 laptop is so powerful and they got this mighty i5 processor at like 2.8 ghz, but the whole thing overheats and isnt comfortable to play on. Desktop performance, cooling, customizability, price, lastivity annihilate laptops whose one and only advantage is portability.

25GB's? I remember my Nvidia 9500GT had 32GB of bandwidth and that card is weaker then a 4670 and a A10 is a little more powerful then a 5670.
