At the AMD Fusion Development Summit (AFDS), Advanced Micro Devices for the first time demonstrated its next-generation code-named Trinity accelerated processing unit (APU) in action. This is the first evidence that the chip, which will be released as AMD's mainstream solution in 2012, is already working. The product is expected to be 50% faster than existing offerings.

"Our next product called Trinity is lined up for next year. [The chip's] performance will be at least 50% faster than [400GFLOPS] performance you see today from the Llano. Think less than ten years from now, 2020, 10TFLOPS performance in a notebook," said Rick Bergman, senior vice president and general manager of AMD products group.

Trinity is the first microprocessor that AMD showcased physically that features the company's next-generation Bulldozer x86 processing engines along with a new-generation Radeon graphics engine (potentially utilizing VLIW4 micro-architecture).

The live demonstration of Trinity included playback of a high-definition video along with Windows operating system. The company decided not to showcase any performance-demanding applications, therefore, it is unknown whether the firm is glad with its first Trinity silicon, which is made using 32nm process technology.

It is noteworthy that Mr. Bergman did not indicate whether Trinity will be available in the first half of 2012, or in the second half of the year. For AMD, it is now crucial to introduce its next-generation APU around the same time when Intel Corp.'s delayed code-named Ivy Bridge chip hits the market in early Q2 2012 in order to compete for design wins head-to-head with the market leader.

"We actually decided to surprise you here and actually show you a demo of Trinity platform. What you saw here was high-definition video playback, you also saw that Windows is running just fine," said Mr. Bergman.

Developers of microprocessors traditionally demonstrate working samples of their products about a year ahead of the commercial release. AMD said that it has had Trinity silicon for several weeks now.

what will be the prime driver for the increase in the GFLOPS horsepower. I sure hope that it is the CPU part of the APU as that is what is currently lacking in the Llano

It is, Enhanced K10.5 -> Enhanced Bulldozer

While CPU will become faster as a result of Bulldozer cores, the only way to have such an increase in TFLOPs is from the GPU. Current CPUs don't even break 100 Gflops. So there is no way this growth is coming primarily from the CPU. Also, from his comments, it's very clear he is referring to the GPU since 400Gflops in Llano is referring to the GPU (since that's not possible on a CPU, even in 2012).

AMD made a wise choice buying ATI.

it my have been little premature, nearly breaking the company, but it is finally getting the rewards that are going to pay off big for the rest of their near-future.

AMD Fusion is getting into it's stride now, and later the CPU's traditional floating point units and the GPU's SIMD units will merge, further blurring the definition of a CPU and GPU, eventually we'll just call them "processors".

Intel have also started to exhibit behaviours that show the evolution of such processors with their development of the CPU's "ring bus", a feature that GPU's have had for years.

the differences are disappearing, eventually there will be a time when we will only remember from history what a "CPU" or "GPU" was.

that time is approaching fast, and AMD have the lead on realising that future sooner, even if Intel have the raw power for a CPU now.

Worth noting AMD seems to be switching from VLIW to non-VLIW for the Radeon 7000 series. I would hope that Trinity includes this architecture change as well.

Supposed slide:


I think 50% greater GPU flops would mean something like 512 shader processors @ a higher clockspeed. Hopefully they include sideport to GDDR5 next time, since obviously another memory controller isn't going to happen and shared memory bandwidth is putting major hurt on Llano.

AMD's marketing material is talking about single-precision floating performance of the GPU side. Not the Bulldozer-based CPU side.

To be realistic and get an approximate idea of improvement...

Llano's IGP (top model) => ~400 GigaFLOPS

It sits right between Radeon HD 5550 (352 GigaFLOPS) and HD 5570 (520 GigaFLOPS)...This is confirmed by Anandtech's desktop Llano article with DDR3-1866 memory.
See here =>

Now AMD (at their Fusion Developer Summit), says Trinity's IGP will be 50% better than Llano for computational performance. (Let's stick with the 50% as the bare minimum.)

So Trinity's IGP => ~600 GigaFLOPS

...Which puts it at the heels of a Radeon HD 5670 (620 GigaFLOPS). Its an incremental improvement over Llano in the GPU side.

One must also consider the bandwidth limitations. The GPU is bandwidth hungry. This is demonstrated in Anandtech's numbers and the performance improvement when they used DDR3-1333 vs DDR3-1866 sticks.

I highly suspect AMD will consider adding an additional memory channel to alleviate a performance bottleneck. Its more beneficial per dollar, to add a third channel of DDR3-1866 than it is to stick with dual channel and bump up to DDR3-2133. (The next official JEDEC standard in DDR3 speeds.)

Dual channel DDR3-1866 offers 29.9 GB/s
Dual channel DDR3-2133 offers 34.1 GB/s
=> About a 15% increase.

Dual channel DDR3-1866 offers 29.9 GB/s
Triple channel DDR3-1866 offers 44.8 GB/s
=> About a 49% increase.

...But this is only economically realistic with desktop versions. (If they do this, you're going to need to buy a new motherboard; as it requires a new socket and physical memory configuration.)

Its very likely they'll keep it dual-channel for notebook versions and bump up RAM speeds from DDR3-1333 and -1600 in mobile Llano to DDR3-1866 for mobile version of Trinity.

Overall, I like the idea of the APU and Llano is the right direction. But I will wait for Trinity as my next major upgrade.

Hopefully the industry will move to a new Dimm Socket format
One dimm slot with 2, 3 or 4 distinct memory divisions
in essence dual, tri or quad channel on a single stick
in which case you can buy single double tri or quad band memory stick with different price points.
making it a realistic solution for mobile

I think this methodology occurred in the past from shift from Fastpage to EDO ram

well, the top model with 400 Sp already has 480 GFlops at 600 mhz.
side port memory would be more better performance wise and more cost effective than a 3rd mem channel. a single 64 bit channel(for side port) with ddr5 at 3200-3600 mhz would equal Llano's WHOLE 128 bit memory controller at 1600-1800 mhz. so, just by adding 512 MB of 64 bit ddr5 would, in essence, double the total bandwidth available.
plus, adding side port may not require a new socket or any big changes in a mobo's wiring pattern- i've heard that Llano's socket was designed with consideration towards side port.
