The NDA is over and we can finally tell you all about the new generation of Trinity, especially the compute portion which we were not allowed to discuss in the controversial preview. Part of the good news is the price, Legit Reviews found the highest MSRP is $122 for the A10-5800K and it is currently available, though at $130. The performance increase from the previous generation is decent for multicore applications though not so much for single threaded applications, overall you can expect general computing performance in line with Core i3 but not Core i5. Gaming on the other hand did show much improvement, especially with you compare the built in HD7660D to Intel's current HD4000 and HD3500. You can catch Josh's review right here.
"The internal testing from AMD that we can see above shows a 37% increase in the 3DMark 11 score between the first generation A-Series Llano and this generation of A-Series Trinity. While our numbers don't match their numbers exactly, our Llano system scored 1115 3Dmarks while the AMD internal testing showed 1150 3DMarks. Our AMD A10-5800K scored 1521 3DMarks while they scored 1570. The overall difference was remarkably similar, AMD is boasting an increase of 37% and we saw a difference of 36.4%..."

Trinity Finally Comes to the Desktop
Trinity. Where to start? I find myself asking that question, as the road to this release is somewhat tortuous. Trinity, as a product code name, came around in early 2011. The first working silicon was shown that Summer. The first actual release of product was the mobile part in late Spring of this year. Throughout the summer notebook designs based on Trinity started to trickle out. Today we cover the release of the desktop versions of this product.
AMD has certainly had its ups and downs when it comes to APU releases. Their first real APU was Zacate, based on the new Bobcat CPU architecture. This product was an unmitigated success for AMD. Llano, on the other hand, had a pretty rocky start. Production and various supply issues caused it to be far less of a success than hoped. These issues were oddly enough not cleared up until late Spring of this year. By then mobile Trinity was out and people were looking towards the desktop version of the chip. AMD saw the situation, and the massive supply of Llano chips that it had, and decided to delay introduction of desktop Trinity until a later date.
To say that expectations for Trinity are high is an understatement. AMD has been on the ropes for quite a few years in terms of CPU performance. While the Phenom II series were at least competitive with the Core 2 Duo and Quad chips, they did not match up well against the latest i7/i5/i3 series of parts. Bulldozer was supposed to erase the processor advantage Intel had, but it came out of the oven as a seemingly half baked part. Piledriver was designed to succeed Bulldozer, and is supposed to shore up the architecture to make it more competitive. Piledriver is the basis of Trinity. Piledriver does sport significant improvements in clockspeed, power consumption, and IPC (instructions per clock). People are hopeful that Trinity would be able to match the performance of current Ivy Bridge processors from Intel, or at least get close.
So does it match Intel? In ways, I suppose. How much better is it than Bulldozer? That particular answer is actually a bit surprising. Is it really that much of a step above Llano? Yet another somewhat surprising answer for that particular question. Make no mistake, Trinity for desktop is a major launch for AMD, and their continued existence as a CPU manufacturer depends heavily on this part.

You've seen the slides everywhere and read through what Josh could observe and predict from those slides but at the end of Hot Chips will still know little more about the core everyone is waiting for. The slides show a core little changed from Bulldozer, which is exactly what we've been expecting as AMD has always described Steamroller as a refined Bulldozer design, improving the existing architecture as opposed to a complete redesign. SemiAccurate did pull out one little gem which might mean good news for both AMD and consumers which pertains to the high density libraries slide. The 30% decrease in size and power consumption seems to have been implemented by simply using the high density libraries that AMD uses for GPUs. As this library already exists, AMD didn't need to spend money to develop it, they essentially managed this 30% improvement with a button press, as SemiAccurate put it. This could well mean that Steamroller will either come out at a comparatively low price or will give AMD higher profit margins ... or a mix of both.
"With that in mind, the HDL slide was rather interesting. AMD is claiming that if you rebuild Bulldozer with an HDL library, the resulting chip has a 30% decrease in size and power use. To AMD at least, this is worth a full shrink, but we only buy that claim if it is 30% smaller and 30% less power hungry, not 30% in aggregate. That said, it is a massive gain with just a button press.
AMD should be applauded, or it would have been, but during the keynote, the one thing that kept going through my mind was, “Why didn’t they do this 5 years ago?”. If you can get 30% from changing out a library to the ones you build your GPUs with, didn’t someone test this out before you decided on layout tools?"

Ah, the end of August. School is about to start. American college football is about to get underway. Hot Chips is now in full swing. I guess the end of August caters to all sorts of people. For the people who are most interested in Hot Chips, the amount of information on next generation CPU architectures is something to really look forward to. AMD is taking this opportunity to give us a few tantalizing bits of information about their next generation Steamroller core which will be introduced with the codenamed “Kaveri” APU due out in 2013.
AMD is seemingly on the brink of releasing the latest architectural update with Vishera. This is a Piledriver+ based CPU that will find its way into AM3+ sockets. On the server side it is expected that the Abu Dhabi processors will also be released in a late September timeframe. Trinity was the first example of a Piledriver based product, and it showed markedly improved thermals as compared to previous Bulldozer based products, and featured a nice little bump in IPC in both single and multi-threaded applications. Vishera and Abu Dhabi look to be Piledriver+, which essentially means that there are a few more tweaks in the design that *should* allow it to go faster per clock than Trinity. There have been a few performance leaks so far, but nothing that has been concrete (or has shown final production-ready silicon).
Until that time when Vishera and its ilk are released, AMD is teasing us with some Steamroller information. This presentation is featured at Hotchips today (August 28). It is a very general overview of improvements, but very few details about how AMD is achieving increased performance with this next gen architecture are given. So with that, I will dive into what information we have.
Less Risk, Faster Product Development and Introduction
There have been quite a few articles lately about the upcoming Bulldozer refresh from AMD, but a lot of the information that they have posted is not new. I have put together a few things that seem to have escaped a lot of these articles, and shine a light on what I consider the most important aspects of these upcoming releases. The positive thing that most of these articles have achieved is increasing interest in AMD’s upcoming products, and what they might do for that company and the industry in general.
The original FX-8150 hopefully will only be a slightly embarrasing memory for AMD come Q3/Q4 of this year.
The current Bulldozer architecture that powers the AMD FX series of processors is not exactly an optimal solution. It works, and seems to do fine, but it does not surpass the performance of the previous generation Phenom II X6 series of chips in any meaningful way. Let us not mention how it compares to Intel’s Sandy Bridge and Ivy Bridge products. It is not that the design is inherently flawed or bad, but rather that it was a unique avenue of thought that was not completely optimized. The train of thought is that AMD seems to have given up on the high single threaded performance that Intel has excelled at for some time. Instead they are going for good single threaded performance, and outstanding multi-threaded performance. To achieve this they had to rethink how to essentially make the processor as wide as possible, keep the die size and TDP down to reasonable sizes, and still achieve a decent amount of performance in single threaded applications.
Bulldozer was meant to address this idea, and its success is debatable. The processor works, it shows up as an eight logical core processor, and it seems to scale well with multi-threading. The problem, as stated before, is that it does not perform like a next generation part. In fact, it is often compared to Intel’s Prescott, which was a larger chip on a smaller process than the previous Northwood processor, but did not outperform the earlier part in any meaningful way (except in heat production). The difference between Intel and AMD in this aspect is that as compared to Prescott, Bulldozer as an entirely new architecture as compared to the Prescott/Northwood lineage. AMD has radically changed the way it designs processors. Taking some lessons from the graphics arm of the company and their successful Radeon brand, AMD is applying that train of thought to processors.
AMD Gives a Glimpse of the Near Future
AMD has released an updated roadmap for these next two years, and the information contained within is quite revealing of where AMD is going and how they are shifting their lineup to be less dependent on a single manufacturer. The Financial Analyst Day has brought a few surprises of where AMD is headed, and how they will get there. Rory Read and Mark Papermaster have brought a new level of energy to the company that seemingly has been either absent or muted. Sometimes a new set of eyes on a problem, or in this case the attitudes and culture of a company, can bring about significant changes for the positive. From what we have seen so far from Rory and company is a new energy and direction for AMD. While AMD is still sticking to their roots, they are looking to further expand upon their expertise in some areas, all the while being flexible enough to license products from other companies that are far enough away from AMD's core competence that it pays to license rather than force engineers to re-invent the wheel.
The roadmaps cover graphics, desktop, mobile, and server products through 2013.
This first slide is a snapshot of the current and upcoming APU lineup. Southern Islands is the codename for the recently released HD 7000 series of desktop parts. This will cover products from the 7700 level on up to the top end 7990. Of great interest are the Brazos 2.0 and Hondo chips. AMD had cancelled the "Krishna" series of chips which would have been based on Bobcat cores up to 4 on 28 nm. Details are still pending, but it seems Brazos 2.0 will still be 40 nm parts but much more refined so they can be clocked higher and still pull less power. Hondo looks to be the basic Brazos core, but for Ultra Low Power (lower clocks, possibly disabled units, etc.) which would presumably scale to 5 watts and possibly lower.
