Intel Releases 16GB Xeon Phi
Intel has announced five Xeon Phi accelerators including a high density add-in card while upping memory capacity to 16GB.
Intel has managed to get its Xeon Phi accelerator cards to power the Tianhe-2 cluster to the summit of the Top 500 list, however the firm isn’t waiting around to bring out new products. At the International Supercomputing show, Intel extended its Xeon Phi range with five new products, all of which have more than one TFLOPS double precision floating point performance, and the Xeon Phi 7120P and 7120X cards, which have 16GB of GDDR5 memory.
Intel’s Xeon Phi 7120P and 7120X cards have peak double precision floating point performance of over 1.2 TFLOPS, with 352GB/s bandwidth to the 16GB of GDDR5 memory. The firm also updated its more modest Xeon Phi 3100 series with the 3120P and 3120A cards, both with more than one TFLOPS of double precision floating point performance and 6GB of GDDR5 memory with bandwidth of 240GB/s.
Intel has also brought out the Xeon Phi 5120D, a high density card that uses mini PCI-Express slots. The firm said that the Xeon Phi 5120D card offers double precision floating point performance of more than one TFLOPS and 8GB of GDDR5 memory with bandwidth greater than 300GB/s.
That Intel is concentrating on double precision floating point performance with its Xeon Phi accelerators highlights the firm’s focus on research rather than graphics rendering or workstation tasks. However the firm’s ability to pack 16GB into its Xeon Phi 7100 series cards is arguably the most important development, as larger locally addressable memory means higher resolution simulations.
Intel clearly seems to believe that there is significant money to be made in the high performance PC market, and despite early reservations from industry observers the firm seems to be ramping up its Xeon Phi range at a rate that will start to give rival GPGPU accelerator designer Nvidia cause for concern.
Should Investors Dump AMD?
If you have any old AMD shares lying around you might like to sell them as fast as you can, according to the bean counters at Goldman Sachs.
Despite the fact that the company is doing rather well, and its share price is has gone up rapidly over recent months, Goldman Sach analysts claim that the writing is on the wall for AMD. It thinks that AMD shares will be worth just $2.50 soon. The stock’s 50-day moving average is currently $2.98.
The company said that while AMD could clean up in the gaming market even if you take those figures into account the stock is trading at 22 times its 2014 CY EPS estimate. In other words the company’s core PC business is still shagged and still will generate 45 per cent of the company’s 2013 revenue.
“We therefore believe this recent move in the stock is just the latest in a long history of unsustainable rallies, and we are downgrading the stock to Sell. We believe the current multiple is unjustified for any company with such significant exposure to the secularly declining PC market,” the firm’s analyst wrote.
Analysts at Sanford C. Bernstein think that the share price will settle on $2.00 and FBR Capital Markets thinks $3.00. In other words if you want to know what is really happening at AMD you might as well ask the cat, than any Wall Street expert.
AMD Touts Its Memory Architecture

Comments Off on AMD Touts Its Memory Architecture
AMD has said the memory architecture in its heterogeneous system architecture (HSA) will move management of CPU and GPU memory coherency from the developer’s hands down to the hardware.
While AMD has been churning out accelerated processing units (APUs) for the best part of two years now, the firm’s HSA is the technology that will really enable developers to make use of the GPU. The firm revealed some details of the memory architecture that will form one of the key parts of HSA and said that data coherency will be handled by the hardware rather than software developers.
AMD’s HSA chips, the first of which will be Kaveri, will allow both the CPU and GPU to access system memory directly. The firm said that this will eliminate the need to copy data to the GPU, an operation that adds significant latency and can wipe out any gains in performance from GPU parallel processing.
According to AMD, the memory architecture that it calls HUMA – heterogeneous unified memory access, a play on unified memory access – will handle concurrency between the CPU and GPU at the silicon level. AMD corporate fellow Phil Rogers said that developers should not have to worry about whether the CPU or GPU is accessing a particular memory address, and similarly he claimed that operating system vendors prefer that memory concurrency be handled at the silicon level.
Rogers also talked up the ability of the GPU to take page faults and that HUMA will allow GPUs to use memory pointers, in the same way that CPUs dereference pointers to access memory. He said that the CPU will be able to pass a memory pointer to the GPU, in the same way that a programmer may pass a pointer between threads running on a CPU.
AMD has said that its first HSA-compliant chip codenamed Kaveri will tip up later this year. While AMD’s decision to give GPUs access to DDR3 memory will mean lower bandwidth than GPGPU accelerators that make use of GDDR5 memory, the ability to address hundreds of gigabytes of RAM will interest a great many developers. AMD hopes that they will pick up the Kaveri chip to see just what is possible.
AMD’s Richland Coming In June
Richland is set to replace AMD’s Virgo platform, powered by Trinity processors, and this change will happen in June 2013, most likely coinciding with Computex 2013.
AMD has just launched the first batch of Richland mobile APUs and we still have to see some notebook designs hitting the market. We wrote about mobile Richland APUs.
As of late last year Desktop Richland was always set to launch in June 2013 and the fastest of them is the A10 6800K, clocked at 4.1GHz and 4.4 with Turbo. It also features Radeon HD 8670D graphics that run at 844 MHz. This is the fastest Richland part and it comes unlocked, ready to replace the current AMD A10 5800K. In Europe, the A10 5800K currently sells for 112, while in US the same CPU sells for $129.00 (boxed).
The alpha dog A10 6800K is followed by A10 6700, A8 6600K (Unlocked) and A8 6500. AMD has a mix of 100W and 65W quad-core Richland desktop SKUs. There will be a single A6 6400K (Unlocked) SKU and the A4 6300, both dual-cores with 65W TDP.
Production ready samples were churned out in late January, while volume production is scheduled for late March 2013. The announcement was always scheduled for June 2013 and Richland last through most of 2013, until Kaveri with 28nm Steamroller comes on line.
AMD Goes Richland
There have been more than enough leaks dealing with Richland, AMD’s successor to the Trinity powered Virgo platform, and we even had a chance to see some leaks regarding its successor, codenamed Kaveri. As you may already know, Richland is planned to last through 2013 and it is clear that this is very important chip for AMD.
Based on the Piledriver architecture and built using 32nm technology, Richland will feature an integrated GPU that will be upgraded to Radeon HD 8000 series, a generation ahead of Trinity. As you know, there has been a lot of leaks regarding the Richland parts and the quad-core A10-6800K with Radeon HD 8670D graphics is expected to pack quite a punch. Best of all, Richland will still use the same FM2 socket.
According to our sources, the NDA will be lifted on 12th of March, 8am EST, and we are sure that we will see at least a couple of reviews as well as some additional info regarding the price and the availability date.
AMD Debuts R5000
AMD has released its Firepro R5000 graphics card that has video over IP capabilities.
AMD typically promotes its workstation class Firepro cards using CAD/CAM software, however this time the company is relying on remote viewing as the big selling point for its latest workstation graphics card. AMD’s Firepro R5000 has a GPU that uses its Graphics Core Next (GCN) architecture and Teradici PC video over IP technology to send graphics output over the network.
AMD used its Pitcarin GPU coupled to 2GB of GDDR5 memory in the Firepro R5000. However it isn’t AMD’s GPU that is the big selling point of the Firepro R5000 but rather Teradici’s Tera2240 chip that encrypts display output before sending it out on the network, while supporting up to 60fps (frames per second).
AMD’s Firepro R5000 is intended to be used in render farms, with each final image being sent over an IP network to the end host, and the firm claims that the technology can be used in education, financial and media environments.
The Firepro R5000 is a single slot graphics card that has two mini Displayport outputs that can drive two 2500×1600 displays, however it can also drive a further four remote displays at 1920×1200 resolution by sending data over its RJ45 Ethernet port.
Both AMD and Teradici talked up the low configuration overheads of the Firepro R5000.
AMD 2014 GPU Shaping Up
It looks like AMD has changed its mind about 8000 series graphics, part of the Solar System range of products are slowly showing up in the market.
We got an idea that at some point in the latter part of 2013 there will be some new Sea Islands based graphics line from AMD. What we refer to as the HD 8000 series will come at some point, but AMD can actually end up branding some of these new parts as HD 7000 series products as well.
We were more interested in the big picture, when and whether we will see an entirely new generation in 2014, let’s call it 9000 series for now. Multiple sources have told us that AMD will stick with discrete graphics for the foreseeable future. In 2014, we should see the new HSA generation as well as a steady roadmap for the future beyond 2014.
Remember, AMD still makes quite a bit of money on graphics. It doesn’t makes a lot, but it doesn’t build GPUs at a loss either. Its graphics integrated in CPUs, APUs if you will, also help AMD sell more cores and this is why AMD will stick with making new graphics cores in the future. Technology developed for high-end discrete graphics will trickle down to APUs over time.
Winning all three consoles, including the already launched Nintendo Wii U as well as the soon to launch Xbox 720 (next) and Playstation, 4 will definitely help AMD to perform even better in the future and build closer relations with developers.
Nvidia will have someone to fight in this market and AMD will continue to make discrete graphics cards, as well as notebook chips. Both companies will fight for as much market share as they possibly can and analysts who claim either of them is about to ditch the discrete market is dead wrong.
MSI Shows Off Lightning
MSI’s Geforce GTX 680 Lightning-L graphics card has showed up in Japan and it is possible that we will it in other markets as well.
Apparently not much has been changed compared to the original GTX 680 Lightning, as the PCB and feature set look about the same. The only thing that is different are the clocks. Set at 1019MHz and 1084MHz for base and boost GPU, they are somewhat lower. For comparison, the original GTX 680 Lightning worked at 1100MHz for base and 1176MHz for Boost GPU clock.
The new Lightning is still cooled by MSI’s Twin Frozr IV GPU and it comes with 2GB of GDDR5 memory clocked at 6008MHz. With the same feature set it is expected that this SKU will have a rather decent amount of overclocking headroom as well, depending on the GPU below the cooler, of course.
Although it has not been officially launched, we will surely keep an eye out for it in other markets as well.
AMD Delays Cards
While some people are packing in smoking, AMD thinks it is a good idea to pack in releasing new graphics cards, at least for a year or so.
AMD marketing manager Robert Hallock told Megagames that the company has no intentions to release Radeon HD 8000 series cards for the foreseeable future.
“The HD 7000 Series will remain our primary focus for quite some time,” he said.
When pressed he said that AMD and its partners are happy with the HD 7000 Series, and it will continue to be its emphasis in the channel for the foreseeable future. There had been some rumours that an HD 8000 Series was being developed. However AMD has never confirmed it and so far there has been no proof that any were ready to show up.
Hallock’s comments lend credibility to rumours that the HD 8000 family won’t be out before Q4 2013.
AMD Releases Vishera
Although it was detailed back in August last year, AMD has just now officially released its new “affordable” Vishera based FX-4130 quad-core socket AM3+ CPU.
The new CPU is part of AMD’s 4100-series and is based on Vishera core design with four Piledriver cores. It works at 3.8GHz base clock and can “turbo” up to 3.9GHz. It packs 4MB of L2 and 4MB of L3 cache and has a 125W TDP.
According to the slide over at Xbitlabs.com, the FX-4130 replaces the FX-4100 with the same US $101 price but should provide between 3 and 9 percent more performance.
As things get better with Globalfoundries and their 32nm process technology, AMD is expected to introduce new models based on cut-down versions of Vishera, according to the report.
