Time for New Server CPUs!

While the network fabric and optimized motherboard designs were the key features of the micro server, it is clear that there is room for a “specialized micro server CPU” between the current anemic Atoms and the low power Xeons and Opterons.  AMD announced last week the quadcore Opteron-X series, based upon the Jaguar core.   The quadcore X1150 is claimed to perform twice as fast as the current Atoms at 2 GHz, but needs 17W to achieve this. You can lower the power usage by fiddling with a p-state cap in the BIOS. Unfortunately the 9W number that so many publications talked about without further commentary is only achieved at 1 GHz. At that clockspeed the performance per Watt advantage will be negligible compared to the 2 GHz Atom S1260 at 8.5W. The best performance/watt will be achieved somewhere between 1.5 and 2 GHz, but the advantage that the new Opteron-X has over the Atom is not as large as many people thought. Unless of course you can make use of the floating point processing power of the integrated Radeon core in the Opteron X-1250 APU.

But although the new Opteron-X can not offer a massive performance/watt improvement over the Atom, it is a much more attractive micro server chip. It can deliver the “good enough” horsepower that an Atom can not deliver. But then again, the current low power Ivy Bridge based Xeon, the Xeon E3-1220LV2 was already a very good micro server chip.  But those who think that AMD will be contend with an underdog role once again, are wrong.  AMD has a pretty ambitious roadmap to attack this market.

    AMD is no less than doomed if this is all they've got. I say this with sadness and regret.... and anger. There are definitely a few former CEOs who deserve to be publicly beaten.

    They doomed themselves when they chose to leverage half the company for ATI just before the second great depression and they doubled down on defeat when they sold off their greatest asset: their fabs. Then, just to seal the deal, they decided that the longer pipelines and greater complexity that had almost ruined Intel the decade before would save them. Without in-house fabs to achieve the efficiency. Without the talent to realize the vision. Without floating point units...

    I have to disagree. With Ivy Bridge EP Xeons out soon, the Warsaw product is probably too little, too late. However, the Seattle and Berlin CPUs can carve out their niches. Don't underestimate the micro server market. It is similar to x86 server market back in the late 90ies. It started small and in a niche, but it quickly grew upwards.

    Not underestimating the micro server market here. just that I don't have high hope on AMD to execute their roadmap in a timely fashion.

    actually they hit all their launch targets in recent years, even if not always the performance they were hoping for.

    its frustrating to not see Steamroller based 2P and 4P Opterons. AMD has failed badly in execution. The original Bulldozer was released in late Q3 and Q4 2011 . the Piledriver updates happened in Q4 2012. Steamroller based updates should have been released by Q4 2013 or Q1 2014. but now thats not going to be the case. AMD's execution of big core based products has been miserable.
    In Feb 2012 during the Financial Analyst Day , AMD talked of Kaveri being their 2013 APU. By late 2012 it was clear that Steamroller based Kaveri was delayed. So AMD cooked up a mild Trinity update called Richland and marketed it as the new 2013 APU. Whats worse is AMD is hit badly by Globalfoundries screwing up their 28nm bulk process.
    The only hope is that AMD go direct to Excavator for the real next big core based Opteron 2P / 4P products with a DDR4 based new platform in late 2014 or Q1 2015. The question is what process will AMD be using. AMD needs a 20nm process based Excavator product to have any chance against Haswell EP / EX.
    Intel has no competition till late 2014 in the traditional IT server market. AMD 's problem is they are at the mercy of foundries for process tech , which are atleast 1 generation behind Intel and even more if you count features like FINFET. Intel's transistor performance is unmatched. So given AMD are behind on process tech by a generation , they need to out-architect Intel which is a very difficult task. But against all these odds everyone is hoping AMD can compete against Intel in the big core race. lets see what AMD has in store with Excavator based Opteron refreshes.

    AMD isn't in as bad a position as you seem to think. They aren't good competition for Intel in the high end, true, but performance per dollar in the midrange and low range server market is definitely AMD's area of dominance. I have several AMD based Dell R515 machines in my lab. They perform very well, especially as virtual hosts, for a good price range. They're a good $500-700 cheaper than the equal performing Intel based machines, or in other terms, you can get two more cores per socket and two 1TB hard drives for the same price. Don't count them out just yet.

    The problem is that low and middle end don't provide that much of profit, as in AMD as to sell loads of them just to recover the costs of R&D, they don't even have their own fabs anymore so besides paying the R&D they also have to pay someone else to actually make them, plus they will soon have real competition from the ARM cause let's be honest ARM will start eating AMD market share at a much faster rate than eating Intel market share, this cause exactly of what you said, Intel owns the performance sector and the ones that want performance will not consider ARM solutions (for the time being).

    Hector Ruiz was probably one of the worst CEO from the AMD history and just to think he had a bigger pay check that the CEO of Intel makes me wonder how AMD as a company is being run...

    Unfortunately, $500-$700 is often a drop in the bucket compared to the software costs so a lot of businesses will go Intel despite the superior price/performance ratio. Perhaps more worrisome is the fact that AMD chips are simply larger and more costly than their Intel equivalents. If Intel ever decided to lower their profit margins enough, AMD couldn't compete.

    I think AMD's current strategy of capitalizing on GPU tech and integration with SeaMicro tech is the appropriate strategy at the moment. They have no real hope of catching up to Intel's process tech and Intel appears to have a superior big chip architecture even without it. Intel is focused on its small chip architecture and given the general CPU expertise, it is probable that they will catch up their as well. However, Intel has historically been less than proficient in regards to graphics. While the new Iris line is pretty impressive, it is hard to say how much of that is efficient architecture and how much is simple brute force. Also, while the Xeon Phi is making great strides in the highend HPC arena, they simply don't yet have the expertise to leverage their on die graphics for compute as simply and easily as AMD's upcoming Berlin (for mainstream or lowend HPC). The longer AMD can maintain their technical advantage here, the better. Hopefully the can also keep building off of the SeaMicro tech to distinguish themselves from the manufacturers that think they can just throw and ARM chip in their server and call it a day.

    I wouldn't be so sure about computing advantage for AMD:

    AMD was never even with Intel's fabrication technology in the first place. They've always been behind (usually one generation, but sometimes more). The only significant (unique) fab technology I can recall AMD releasing was their Silicon on Insulator (SOI) process, but it was still on a larger node. Also, it wasn't so much that Intel couldn't have used SOI as they just deemed strained silicon more useful for their purposes at the time.

    Intel has always relied on their process advantage as it allows them to implement architectures that are simply impractical on previous process nodes. Need more performance in the same power envelope, use a higher performance architecture with a new process node. Need a lower power envelope with the same performance, a smaller process node can help you maintain the same clock speeds on the same architecture while dropping power. Need new features, such as better power management, to reach your target. A smaller process node gives you more transistors to work with to implement those features within the same die size. As cost is rather directly related to die size, they can even effectively change nothing and reduce cost. For a long time clever designs and lower profit margins had helped AMD compete, but Intel simply has far more leeway to screw up without having an appreciable effect on their final product. One less than optimal move by AMD lands them in budget land with no profit margins.

    ARM based manufacturers seem to have a more optimal architecture (if only slightly) for low power processors than Intel right now. However, Intel's processes advantage has once again allowed them to achieve a rough parity with their newest Atom architecture. If Intel can close the gap in regards to architectural cleverness, then ARM houses will need to close the gap in fab tech. Otherwise, like AMD, they will be stuck in a situation where one wrong move could relegate them to the budget end (of a budget market). Luckily, there are many ARM houses and they aren't all likely to screw up at the same time.
