AMD showed off its first ARM-based “Seattle” processor running on a reference platform motherboard at an event in San Francisco earlier this week. The new chip, which began sampling in March, is slated for general availability in Q4 2014. The “Seattle” processor will be officially labeled the AMD Opteron A1100.
During the press event, AMD demonstrated the Opteron A1100 running on a reference design motherboard (the Seattle Development Platform). The hardware was used to drive a LAMP software stack including an ARM optimized version of Linux based on RHEL, Apache 2.4.6, MySQL 5.5.35, and PHP 5.4.16. The server was then used to host a WordPress blog that included stream-able video.
Of course, the hardware itself is the new and interesting bit and thanks to the event we now have quite a few details to share.
The Opteron A1100 features eight ARM Cortex-A57 cores clocked at 2.0 GHz (or higher). AMD has further packed in an integrated memory controller, TrustZone encryption hardware, and floating point and NEON video acceleration hardware. Like a true SoC, the Opteron A1100 supports 8 lanes of PCI-E 3.0, eight SATA III 6Gbps ports, and two 10GbE network connections.
The Seattle processor has a total of 4MB of L2 cache (each pair of cores shares 1MB of L2) and 8MB L3 cache that all eight cores share. The integrated memory controller supports DDR3 and DDR4 memory in SO-DIMM, unbuffered DIMM, and registered ECC RDIMM forms (only one type per motherboard) enabling the ARM-based platform to be used in a wide range of server environments (enterprise, SMB, and home servers et al).
AMD has stated that the upcoming Opteron A1100 processor delivers between two and four times the performance of the existing Opteron X series (which uses four x86 Jaguar cores clocked at 1.9 GHz). The A1100 has a 25W TDP and is manufactured by Global Foundries. Despite the slight increase in TDP versus the Opteron X series (the Opteron X2150 is a 22W part), AMD claims the increased performance results in notable improvements in compute/watt performance.
AMD has engineered a reference motherboard though partners will also be able to provide customized solutions. The combination of reference motherboard and ARM-based Opteron A1100 is known at the Seattle Development Platform. This reference motherboard features four registered DDR3 DIMM slots for up to 128GB of memory, eight SATA 6Gbps ports, support for standard ATX power supplies, and multiple PCI-E connectors that can be configured to run as a single PCI-E 3.0 x8 slot or two PCI-E 3.0 x4 slots.
The Opteron A1100 is an interesting move from AMD that will target low power servers. the ARM-based server chip has an uphill battle in challenging x86-64 in this space, but the SoC does have several advantages in terms of compute performance per watt and overall cost. AMD has taken the SoC elements (integrated IO, memory, companion processor hardware) of the Opteron X series and its APUs in general, removed the graphics portion, and crammed in as many low power 64-bit ARM cores as possible. This configuration will have advantages over the Opteron X CPU+GPU APU when running applications that use multiple serial threads and can take advantage of large amounts of memory per node (up to 128GB). The A1100 should excel in serving up files and web pages or acting as a caching server where data can be held in memory for fast access.
I am looking forward to the launch as the 64-bit ARM architecture makes its first major inroads into the server market. The benchmarks, and ultimately software stack support, will determine how well it is received and if it ends up being a successful product for AMD, but at the very least it keeps Intel on its toes and offers up an alternative and competitive option.

The Inquirer had a chance to hear more about the upcoming Opteron A111 which contains an ARM Cortex A57. We now know it runs at 2GHz, can address up to 128GB of RAM and has enough channels for 8 drives to be connected to it. While the chips will be able to operate in tandem with traditional x86 server chips the reduction in power needed and heat produced could mean Opteron based servers could be as small as a cellphone. We also know that they will be running on a specially flavoured version of Fedora, read on to see what else was revealed by Ian Drew.

The Inquirer had a chance to talk to Lakshmi Mandyam, the director of Server Systems and Ecosystems at ARM, about their plans for the server room. ARM and their SBSA team have joined forces with Microsoft's Open Technology initiative which is key to AMD's adoption of ARM architecture in their new Opteron series. These projects will offer several key benefits to customers, the open source nature will allow customization in the server room for those customers with specific needs and the know how to implement them and the nature of ARM processors can bring energy bills down. This could also be great news for smaller businesses that require a proper server, they will be able to build that server out of a number of inexpensive ARM based processors instead of having to spend the price of the currently available x86/64 CPUs from Intel and AMD.

The ARMv8 architecture extends the hardware platform to 64-bit. This increase is mostly useful to address massive amounts of memory but can also have other benefits for performance. I think many of us remember the excitement prior to x86-64 and the subsequent let-down when we realized that, for most applications, typical vector extensions kept up in performance especially considering the compatibility issues of the day. It needed to happen but it was a hard sell until... it was just ubiquitous.
AMD has not kept it secret that they are developing 64-bit ARM processors for data centers but, until this week, further details were scarce. Under the codename, "Seattle", these processors will be available in four and eight cores. The Opteron branding will expand beyond x86 to include these new processors. The pitch to enterprises is simple: want both ARM and x86? Why bother with two vendors!
Seattle will also support up to 128GB of ECC memory and 10 Gigabit Ethernet for dense, but power efficient, compute clusters. It will be manufactured on the 28nm process.
The majority of AMD's blog post proclaimed its commitment to software support and it is definitely true that they hold a very high status in both the Linux and Apache Foundations. ARMv8 is supported in Linux starting with kernel 3.7.
Seattle is expected to launch in the second half of 2014.
Retiring the Workhorses
There is an inevitable shift coming. Honestly, this has been quite obvious for some time, but it has just taken AMD a bit longer to get here than many have expected. Some years back we saw AMD release their new motto, “The Future is Fusion”. While many thought it somewhat interesting and trite, it actually foreshadowed the massive shift from monolithic CPU cores to their APUs. Right now AMD’s APUs are doing “ok” in desktops and are gaining traction in mobile applications. What most people do not realize is that AMD will be going all APU all the time in the very near future.
We can look over the past few years and see that AMD has been headed in this direction for some time, but they simply have not had all the materials in place to make this dramatic shift. To get a better understanding of where AMD is heading, how they plan to address multiple markets, and what kind of pressures they are under, we have to look at the two major non-APU markets that AMD is currently hanging onto by a thread. In some ways, timing has been against AMD, not to mention available process technologies.
Kabini is a pretty nifty little chip. So nifty, AMD is actually producing server grade units for the growing micro-server market. As readers may or may not remember, AMD bought up SeaMicro last year to get a better grip on the expanding micro-server market. While there are no official announcements from SeaMicro about offerings utilizing the server-Kabini parts, we can expect there to be sooner as opposed to later.
The Kabini parts (Jaguar + GCN) will be branded Opteron X-series. So far there are two announced products; one utilizes the onboard graphics portion while the other has the GCN based unit disabled. The products have a selectable TDP that ranges from 9 watts to 22 watts. This should allow the vendors to further tailor the chips to their individual solutions.
The X1150 is the GPU-less product with adjustable TDPs ranging from 9 to 17 watts. It is a native quad core product with 2 MB of L2 cache. It can be clocked up to 2 GHz, which we assume is that 17 watts range. The X2150 has an adjustable TDP range from 11 to 22 watts. The four cores can go to a max speed of 1.9 GHz while the GPU can go from 266 MHz up to a max 600 MHz.

AMD64 arrived a decade ago with the launch of the first Opteron processor in April of 2003, back in the days when NVIDIA made motherboards and ATI was a separate company. In those days AMD looked like serious competition for Intel as they were out innovating Intel and competing for Big Blue's niche markets as they were first to cross the GHz line and the first to offer a 64bit architecture on a commercially available platform. At that point Intel actually licensed AMD64, re-branded it as x86-64 and used it on their Xeon processor line, a huge victory for AMD. Unfortunately there was not much in the way of consumer software capable of taking advantage of 64-bit architecture and unfortunately remains so to this day, apart from peoples ability to benefit from the enlarged RAM pool allowed. Take a walk down memory lane at The Inquirer, and remember the good old days when AMD was prospering.

AMD has officially released a number of new server processors based on its latest Piledriver cores. The new Opteron 4300 and Opteron 3300 series processors will replace the 4200 and 3200 series, and are aimed at the server market. The 4300 series uses Socket C32 while the Opteron 3300 processors use socket AM3+. They are significantly cheaper Piledriver-based parts than the higher-end Opteron 6300 series processors. AMD is aiming these lower cost Opterons at servers hosting websites and internal applications for small to medium businesses.
There are a total of nine new Opteron processors, with three being 3300 series an six being 4300 series. Both the 3300 and 4300 series Opterons are socket compatible with the previous generation 3200 and 4200 series respectively, allowing for an upgrade path in existing servers. According to AMD, the new Piledriver-based processors have 24% higher performance per watt and use 15% less power than the previous generation parts based on the SPECpower and SPECint benchmarks. AMD is also touting support for low power 1.25V memory with the new chips.
The chart below details the specifications and pricing all of the new Opteron parts.
The new AMD Opteron 3300 series includes two quad core and one eight core processor. The parts range from 1.9GHz to 2.6GHz base and have TDPs from 25W to 65W for the lowest and top end parts respectively. AMD-P, AMD-V, and AMD Turbo Core technologies are also supported. As far as memory goes, the 3300 series supports up to four DIMMs and 32GB per CPU. Further, a single x16 HyperTransport 3.0 link rated at 5.2GT/s is included.
Moving up to the 4300 series comes with an increase in price but you also get more cores, more memory, and faster clockspeeds. The Opteron 4300 series has one quad core 4310 EE, three six core CPUs, and two eight core parts. Base clocks range from 2.2GHz to 3.1GHz while boost clocks start at 3.0GHz and go to 3.8GHz. On the low end, the Opteron 4310 EE has a 35W TDP and the top-end 4386 has a 95W TDP. The 4300 series supports dual channel DDR3 1866 memory with up to six DIMMs and 192GB per CPU. Moving up from the 3300 series also gets you two x16 HyperTransport 3.0 links at 6.4 GT/s.
The new server processors are available now with prices ranging from $174 to $501. In addition, pre-built server options from Supermicro and Seamicro (SM15000) are currently available, with options from Dell and a number of other companies on the way. The prices seem decent, and these chips could make the base for a nice 2P server that brings you Piledriver improvements for much less than the relatively expensive 6300 series processors that we covered previously.

AMD announced new server processors on Monday based on the same Piledriver architecture used in the Trinity APUs and Vishera desktop CPUs we recently reviewed. With the release of the Opteron 6300 series, AMD is bringing Piledriver to the server room.
The new chips – similar to the desktop counterparts – bring several performance improvements over the previous generation 6200 series Opterons based on the Bulldozer architecture. AMD is positioning the chips as a upgrade path to existing servers and on merits of performance-per-dollar efficiency. As is AMD's fashion, the new chips are competitively priced and "good enough" performance-wise. With 6300, AMD has stated the goal is to reduce the TCO, or Total Cost of Ownership for servers used in data centers, supercomputers, and enterprises by being compatible with existing AMD server platforms with a BIOS upgrade and representing efficiency improvements over previous chips.
The Opteron 6300 series CPUs themselves build upon the Vishera desktop parts by adding more cores and more L3 cache. The server parts will have up to 16 cores clocked at 2.8GHz base and 3.2GHz turbo. They will have TDP ratings between 85W and 140W and will feature prices from $500 to $1,400. On the cache front, the chips have a 16KB L1 data cache per core, 64KB L1 instruction cache per module, 1MB L2 cache per core, and a shared 16MB cache per socket. AMD has included a quad channel memory controller that supports DDR3 up to 1866 MHz and 1.5TB per server in 4P configurations. AMD has rounded out the chips with four x16 HyperTransport 3.0 links rated at 6.4 GT/s per link. Up to 4 processors per server will be supported, which means a maximum of 64 cores.
With Piledriver, AMD added a number of new instructions including FMA3, BMI, and F16c. The company has also implemented server tweaks to the Bulldozer design to improve branch prediction, instructions per clock, scheduling, and reduced the power draw at higher clockspeeds allowing for the chps to clock higher while staying within the same power envelope of the Bulldozer-based Opteron 6200 series.
AMD is using the same socket as the 6200 series processors, and the new chips can be deployed as an upgrade to the old servers without needing a new motherboard.
When pitting the new Opteron 6380 to the previous-generation 6278, AMD is claiming a number of performance increases, including a 24-percent and 40-percent improvement in SPECjob2005 and SPECpower_ssj2008 respectively.
Further, the company is claiming competitive performance in server workloads with the Intel competition. AMD offers up benchmarks showing the Opteron 6380 and Xeon E5-2690 trading wins, with the AMD part being slower in the STREAM benchmark, but being slightly faster in LAMPS and NAMD. The allure of the Opteron, according to AMD is that the AMD part is almost half the price of the Intel processor, and is hoping the lower priced parts will encourage adoption. AMD argues that the money saved could easily go towards more RAM or more storage (or simply be saved of course).
The company has announced that its first major design win is Big Red II supercomputer at Indiana University. Built by Cray, the Big Red II will feature 21,000+ Opteron 6300-series CPU cores paired with NVIDIA GPUs. It represents a massive increase in computing power over IU’s previous Big Red supercomputer with 4,100 CPU cores, and will be used for medical, physics, chemistry, and climate research. Beyond that, AMD has stated more that 30 hardware vendors are slated to introduce servers based on the new Piledriver-based Opteron processors including HP, Dell, Cray, SGI, Supermicro, Sugon, and (of course) SeaMicro. On the software side of things, AMD is working with Microsoft, VMware, Xen, Red Hat, and Openstack. The company also stated that it is leaning on the experience and knowledge gained from the HSA Foundation to improve software support and guide the future direction of Opteron development.
The Opteron 6300 series is an interesting release that brings several improvements to the company’s server chip offerings. At launch, there are 10 processors to choose from, ranging from the quad core 6308 clocked at 3.5GHz for $501 to the top-end 6386 SE with 16 cores (2.8GHz base, 3.5GHz max turbo) and a $1,392 price tag. The 6366HE is an interesting part as well. It is the same price as the 12-core, 115W TDP Opteron 6348, but its has 16 lower-clocked cores and an 85W TDP. With the non-HE edition processors with 16 cores starting at $703, the 6366HE for $575 is a decent deal if you need multi-threading more than a fewer number of higher clocked cores.
Another bit that I found intriguing is that in a few years, AMD will (likely, if all goes according to plan) be offering processors for just about every type of server. They will have low cost, low power ARM Cortex-A57 based chips, Accelerated Processing Units (APUs) well suited to mixed workloads including GPU-accelerated tasks, and CPU-only chips with lots of traditional x86-64 cores. It seems that Intel will continue to hold the high end on pure performance, but AMD and its SeaMicro server division have not given up competing in the server room by a long shot.
