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.

Comments Off on Microsoft Looks Into Smart Watches
Microsoft is developing designs for a touch-enabled smart watch, joining a number of other large competitors like Samsung Electronics and Apple who are said to be working on similar devices, according to a recent report.
Executives at suppliers to Microsoft told The Wall Street Journal that the company was sourcing components for the prototype of what could potentially be a “watch-style device.”
Microsoft has, for example, requested 1.5-inch displays from component makers for the prototype, an executive at a component supplier told the newspaper. It is unclear whether the company will decide to go ahead with the watch, the newspaper added.
Microsoft could not be immediately reached for comment.
A large number of vendors are looking at new product categories beyond smartphones and tablets.
This isn’t the first time, however, that Microsoft may be looking at watches as a product. It launched a smart wrist watch around a concept called Smart Personal Object Technology it unveiled in 2002, but withdrew it after a lackluster performance.
The Redmond, Wash., company is seeing its key PC market under threat from smartphones and tablets, and the failure of its new Windows 8 operating system to boost sales significantly. IDC said last week that first quarter PC shipments totaled 76.3 million units, down 13.9% compared to the same quarter last year. (The decline was worse than the 7.7% previously forecast by the analyst firm, and the market could be headed into further contraction, the research firm added.
AMC Goes To The Clouds
Applied Micro Circuits has released its cloud chip which takes networking and computing and crams it all onto one SoC.
The X-Gene server on a chip, is being billed as the first 64-bit-capable ARM-based server in existence. According to the company it is the first chip to contain a software-defined network (SDN) controller on the die that will offer network services such as load balancing and ensuring service-level agreements on the chip.
Paramesh Gopi, president and CEO of Applied Micro, said that these new chips have now made it past the prototype stage and are being used by Dell and Red Hat. Gopi expects physical servers containing the X-Gene to hit the market by the end of this year.
The chip is manufactured at 40 nanometers and has eight 2.4 GHz ARM cores, four smaller ARM Cortex A5 cores running the SDN controller software, four 10-gigabit ethernet ports, and various ports that can support more Ethernet, SSDs, accelerator cards such as those from Fusion-io or SATA drives.
The cost of ownership, which includes power requirements are about half of that of a comparable x86 product, but wouldn’t discuss actual power consumption, the company claims.
Is Apple Really Security Conscious?
Is Apple proving how clueless it is about security by backing a method of replacing passwords with fingerprint readers?
Just days after a scandal where a South American hospital was staffed by phantom doctors who used silicon fingers of their colleagues to convince administrators’ finger print readers that they were working, Apple has decided that they are the perfect form of security.
Word on the street is that Apple is said to be planning to introduce an iPhone that can be unlocked by the owner’s fingerprint. Speculation about Apple’s plans for fingerprint recognition began last summer when the iPhone maker bought bio-metric security firm AuthenTec for $335 million.
It is believed that the iPhone 5S will have a fingerprint chip under the Home button, to “improve security and usability.” Meanwhile in an engineering journal, two Google security experts outlined plans for an ID ring or smartphone chip that could replace online passwords, which is a lot sexier than fingerprint scanning.
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.
AMD Offers More Radeon Chips
AMD has announced four Radeon HD 8000M series GPU chips sporting its latest Graphics Core Next (GCN) architecture.
AMD’s GCN architecture made its first appearance in the firm’s ultra high-end mobile chips, however next month’s CES show will see the firm show off laptops featuring four Radeon HD 8000M series chips. The firm’s four Radeon HD 8000M chips are pitched at the mainstream and gaming laptop markets, though the company said that Asus already has a laptop announced that will use the chips in an ‘ultrathin’ design.
AMD’s Radeon HD 8000M series sees the firm split three chips with the same number of stream processors and memory clock speeds that scale up to 1.25GHz but differentiated by their core speeds. The firm’s Radeon HD 8500M, Radeon HD 8600M and Radeon HD 8700M all have 384 stream processors but are clocked up to 650MHz, 775MHz and between 650MHz and 850MHz, respectively.
Topping AMD’s present range is the Radeon HD 8800M, which has 640 stream processors and is clocked at between 650MHz and 700MHz, while its GDDR5 memory is also clocked at 1.25GHz. All of the firm’s chips, by virtue of being based on the GCN architecture, support DirectX 11.1.
AMD said it will launch three more chips in the Radeon HD 8000M series in the second quarter of 2013. According to the firm’s roadmap, two of those chips will sit above the Radeon HD 8800M in terms of performance while the third will straddle somewhere between the Radeon HD 8600M and Radeon HD 8700M.
AMD was tight-lipped on the power figures for its chips, saying that full details of its Radeon HD 8000M series chips will appear at CES, where its partners will tip up with laptops sporting the chips.
