AMD's server team is focusing on value now, performance in the future

AMD recently compared the cost per virtual machine of two eight-core 2.9GHz Xeon E5-2690 processors with 256GB in each node against servers with two 16-core 2.7GHz Opteron 6284SE and only 128GB per node.  Hyperthreading was enabled on the Intel machines so each box presented 64 threads to the VMmark test you can see below.   AMD is hoping to highlight the difference in pricing, while they may perform about 25% slower than an Intel based server, they cost 30% less to purchase, which in racks costing $10,000 or more will add up to some significant savings.  As well The Register talks about the future of AMD's servers, we know that the Abu Dhabi Opteron 6300s for two-socket and four-socket machines, the Seoul Opteron 4300s for two-socket and single-socket machines, and the Delhi Opteron 3300s for single-socket boxes will arrive staggered throughout this year and next, offering some new hope for AMD's processing power.  They also touch on Seamicro and the interconnect technology AMD purchased which could see next generation Opterons working with FirePro cards to really start to offer something new from AMD which could be a big jump in performance compared to their current server offerings.


"It is not as much fun to be in the server part of Advanced Micro Devices these days, with Intel surging in the server racket and expanding out to switching and storage with its Xeon processors and Intel more or less counting the substantial innovations that AMD's engineers crafted for the Opterons a decade ago. The good news if you like a good fight is that there is a whole new management and engineering team at AMD now, and they not only understand that AMD has to do some serious innovating, but they are itching for the fight."

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 drops a module and keeps its socket

One of the many interesting bits of information AMD disseminated at this years FAD started some conjecture about possible problems with Piledriver.  It seems that somewhere along the line AMD dropped a module on the Seou chip bringing its core count down from 10 to 8.  Once the hue and cry died down a bit a theory propounded by SemiAccurate offered a sensible theory for the change.  It seems likely that AMD initially developed this family of chips with the belief that DDR4 would have made it to market by now, perhaps in compensation for the delay in adopting DDR3.  Unfortunately DDR4 is nowhere to be seen outside of testing laboratories which has had an effect on AMD's development plans.  Without new memory there is no extra memory bandwidth which will in turn starve the extra cores on the chip and likely slow the performance of all of the cores.  Instead AMD opted to trim out the extra cores and as a benefit they get to utilize their existing sockets as opposed to introducing another one. 


"A lot of people are in a tizzy because AMD (NYSE:AMD) has changed the upcoming Seoul CPU from 10 to 8 cores. The general responses ranges from AMD incompetence to apocalypse, but all it really signals is a lack of technical understanding on their behalf.

The slide in question was the server roadmap we wrote up here. It introduces Piledriver cored Abu Dhabi and Seoul chips, successors to the Bulldozer based Interlagos and Valencia respectively. The base part has 4 modules/8 cores, and the bigger variant is two of those in a package. The big controversy is that they were supposed to be 5 module/10 core parts."
