Got one noob question I wanna ask. If I buy the Kaveri apu without a display card and a motherboard that doesn't have built-in display card....... How am I going to connect to the monitor because it would not have a video port to connect to rite? This is an wrong setup right? So at the end the apu still need to stick to another display card or built-in display izzit?

Follow up,

This slide was proven fake by AMD Manager of APU/CPU Product Reviews James Prior.
Yet the future of FX lineup is still unknown since the real roadmap shown Vishera will stay throughout 2014.

Earlier this year AMD announced they will not release a new GPU in 2013 yet a couple of month later they released HD7790 which was a new GPU with an improved architecture and in Q4 they released 7000 series successor, the R9-290s.  laugh.gif
*
Fake or not, the AM3+ is a dead end and its highly unlikely that an 8 core steamroller will ever come out. AMD has slashed headcount twice around last year and so its going to be highly improbable that AMD can continue on the existing AM3+ roadmap.

The 7790 and the r9-290 weren't the 8 series which people were expecting but rebadged 7 series Tahiti era cards. The r9-260 will be one of the first new gcn2 cards.

i think if AMD want to stick with piledriver, it is better they introduce new core based on piledriver but lower TDP for example 8350 performance but wattage at 100,

There is R9-260? I thought R7-260 which also support true audio same like 7790. In fact the are the same just rebadged process plus some tweaking. laugh.gif

Yeah I did say that. "Yet the future of FX lineup is still unknown since the real roadmap shown Vishera will stay throughout 2014."

HD7790 and R9-290 is not rebadged. HD7790 is Bonaire and R9-290 series is Hawaii not Tahiti. There's no R9-260, only R7-260 which is a rebadged of HD7790 + TrueAudio chip.

Still unknown? AMD is trying hard not to say that the product line is dead.The context of your earlier post makes it sound like the FX is going to continue post-Vishera which is highly unlikely. AMD is in a worse position several years ago with less resources to devote to continuing their big core consumer line.

I made a typo. What I was getting at was that the 2xx series are very small tweaks from the 7 series, not even a real tick (using the tock tock analogy).

You sound as if all the problems that AMD is having was intentionally directed for the last 7 years to get to HSA which doesn't make sense. The path AMD is taking now is more unplanned and remedial.

Around 7 years ago, AMD had better performing solutions vs Intel. They were the first to write the spec for x64 and had X2s and could charge premium prices for them which was a turnaround from their usual low margin price slashing strategy. Then AMD messed up big time by delaying the development of the K10 which also pushed Bulldozer ahead by a year or two. AMD paid way too much for ATI, abandoned gpgpu (for HSA?) and seemed to ignore ATI.It was only after Rory Read came in and figured out that BD/PD/SD disaster wasn't going anywhere, decided to cut AMDs losses by slashing headcount and focusing on smaller FM2 APUs. The the console deal (which Nvidia rejected for being too low margin) allowed AMD to leverage its mantle api which otherwise wasn't going to happen. And its still a open question on whether the market will be willing to take on a new proprietary api.

After much research. There is R9 -260 Just naming scheme for oem. Its actually the same with R7 - 260X sweat.gif

I think amd is not focusing on the next gigahertz big core cpu. They are now focusing on the software side. To optimize the instruction set to their cpu and gpu. The creation of mantel and the push of HSA foundation shows this. Well intel do show some of the bench marking software are siding with intel. whistling.gif

AMD will never match Intel blow for blow in a conventional market. Intel simply have too much money. Their fabs alone will keep them ahead. Let alone their core architecture improvements every tick tock.

AMD realises this, so they decided to be a market disruptor. They see potential in changing the conventional market from a cpu/gpu market to the apu. This allows them to keep a lead because Intel will not like nor want a disruption in the market, especially after they have invested so much and have created such a huge lead. This will cause Intel to be slow to adopt the new technology, allowing AMD to have some breathing space while they create the technology and the market for the apu.

They have sacrificed the past 7 or so years for this and now they are at the culmination of all their efforts. They are pushing HSA and things like mantel. Let's see if their gamble pays off. Personally, I thought it would be difficult for them to convince the market to change the programming landscape to take advantage of apus, but the recent XBox and PS4 wins changed all that. Those were brilliant wins. It looks like the market will adopt the new programming standards to take advantage of apus sooner rather than later.

Now the question becomes, how much of a lead AMD can make and how Intel will adjust to the market trends. Execution for AMD is critical here. They need to ensure their new core apus come out timely and perform up to par without the huge power consumption issues of Bulldozer (having ditched Global Foundries, that is less of an issue now). They need to ensure HSA and Mantel take off. With the XBox and PS4, they have the leverage to push these forward. They cannot make any mistakes and they need to hammer home their lead. Intel has already shown they can make cpu and gpu on die and shown they can catch up with Qualcomm in only 2 generations. And they have the advantage of a 14nm fab.

imblibug Mantle - the way it mean to be "paid" in red color. BF4 mantle version will be available on end of this month. Its too early to tell whether it will be success or not.

AMD messed up badly in last 7 years is due to management issues. Lets hope Mr Rory can guide AMD to get out of troubles. HSA is AMD's the biggest bet.

Most of members of HSA foundation still wait and see how AMD's implementation on X86 and ARM cores. They never announce anything about HSA implementation on their product yet.

AMD's product cycles are going to delay alot due to GF(incompetent and AMD still has to pay them...) and TSMC(manufacturing capacity). And this issues affect AMD's design considerations on many upcoming products. I believe Kaveri graphics might facing challengeds from Intel HD graphics(IRIS or later).

Actually it does. It's even been stated in a few interviews. The whole point of AMD buying ATI was to eventually lead to an APU. ATI was bought in 2006. They have spent those few years, first merging the companies, and then merging the architecture of the CPU and GPU. They're doing something that has never been done before. It took them years of R&D to get to where they are.

The first core to be designed for this merger purpose was Bulldozer. While it had an impressive 8 cores, each core shared 1 FPU operations with another core, which essentially handicaps the core. The whole point of that was because FPU operations was meant to be offloaded to the GPU. This is the reason why Bulldozer sucked so badly, because it had no GPU to offload FPU operations to, so it had very poor IPC compared to Intel which meant it totally depended on clockspeed to claw back some parity with Intel. Which obviously never happened, with Bulldozer having poor power consumption and yield, etc.

That's true for products on 32nm. IINM, 2014 onwards, AMD will be moving everything to 28nm which is TSMC. So moving forward, the main constraint will only be production capacity of TSMC. It's true though, that GF really screwed AMD over and set them back behind 1 year in their schedule.

I believe IRIS is still not on par with APUs, but they're now in the same ball park. It's frightening how Intel can catch up if they really want to.

But how was Bulldozer going to be an APU when it was already running hot at at a large chip size at what 1.1B transistors? Slapping on more transistors would make the whole project infeasible. And Bulldozer also had relatively poor ipc for its integer cores so it wasn't just a problem of having less fpus. Llano wasn't competitive with i3 in integer heavy benchmarks. Llanos fusion style gpu wasn't that useful outside of gaming either.

Bulldozer was a template for future CPUs in APU. You're right though. Bulldozer suffered not just from the FPU design, but inefficiencies in areas such as cache latencies really handicapped it.

Llano doesn't use Bulldozer, IINM. It was K10 and then Piledriver (Trinity and Richland) in APUs. The first gen APUs weren't competitive for obvious reasons. The knowledge and expertise just wasn't there yet. Adoption of heaviliy multithreaded and APU accelerated programming was also very limited. Most applications used 1 - 3 cores and GPU acceleration of normal applications like photoshop didn't even exist.

PS: It appears I'm mistaken about 28nm for AMD. They've gone back to GF (presumably because TSMC couldn't match demand?) Please don't screw this up again. icon_question.gif icon_question.gif icon_question.gif

Probably. And already, from reviews I read, they're already catching up in terms of power consumption and performance.

From Intel's perspective, there's no incentive for Intel to go into APU right now. They're probably gonna let AMD suffer through all the pains of creating a market for APUs alone and when the market is big enough, they'll just jump in and catch up within a couple of generations. No harm done to them. They'll just sit there and milk the current CPU market as kings of CPU while they wait.

Like this, AMD better prepare the incoming Excavator lineup product on time. I heard GF still struggling with 28nm productions I hope AMD can get rid of this bad partner. TSMC starts testing with 20nm production and Intel is running 14nm production as we speak.

Bulldozer doesn't have an APU architecture. Bulldozer was always going to be competing with Intel's big core cpus.
The first APUs the Fusion/HSA line starting with the Llano which has an integrated gpu. Trinity and the upcoming Kaveri have more hardware which provides better integration of the cpu/gpu.

You're correct about the Llano using K10 cores. I got mixed up because AMD skipped over K9.
