There is a new Linux kernel in the wild today and it comes with a lot of enhancements. IPTables has been replaced with the NFTables packet filtering and firewall engine, with backwards compatibility for those who actually forced IPTables to behave. There is a new scalable block layer to deal with the previously unreachable I/O that PCIe SSDs can reach and designed specifically for multi-core systems. There is much more but the update many are most excited about is the performance improvements to Radeons of the 7000 family and new models. The benchmarks that Phoronix posted are very impressive but that is only half the story, there are updates to HDMI audio and Radeon Dynamic Power Management is now enabled by default. Check out the full list of updates here.
"Linux kernel 3.13 has been released. This release includes nftables (the successor of iptables); a revamp of the block layer designed for high-performance SSDs; a framework to cap power consumption in Intel RAPL devices; improved squashfs performance; AMD Radeon power management enabled by default and automatic AMD Radeon GPU switching; improved NUMA and hugepage performance; TCP Fast Open enabled by default; support for NFC payments; support for the High-Availability Seamless Redundancy protocol; new drivers; and many other small improvements."

Tagged: r9 m290x, r7 m265, r5 m230, mobile gpu, GCN, amd
AMD recently took the wraps off of its latest mobile GPU series in the form of the R5 M200, R7 M200, and R9 M200 series. Currently, there is one GPU in each respective Rx M200 series including the AMD Radeon R5 M230, R7 M265, and R9 M290X. Do not get too excited, however. All of the new mobile GPUs are based on desktop versions of Volcanic Islands and not AMD's new Hawaii GPUs. As such, the Rx M200 series are essentially rebrands of the Radeon HD 8000M series (which was in turn OEM rebrands of the HD 7000M series) based around AMD's Graphics Core Next 1.0 architecture and specifically the Pitcairn GPU implementation.
All of the Rx M200 series support DirectX 11.2 Tier 1, up to 4GB GDDR5 memory, and at least 320 GCN shader cores. Informatin on the mid-range R7 M265 is scarce, but AMD has released information on the low and high end chips. Further, Computer Base has managed to put together specifications for the R5 M230 and R9 M290X. In short, the R5 M230 is a rebranded HD 8570 with higher clockspeeds and support for more memory while the R9 M290X is a rebranded HD 8970M with official support for DirectX 11.2 Tier 1 (the HD8970M technically supports it as well). A more detailed breakdown is as follows.
The R9 M290X features 1280 shaders clocked at 850MHz/900MHz (base/boost), 80 texture units, and 32 ROPs. OEMs can pair the GPU with up to 4GB of GDDR5 memory clocked at 1,200 MHz on a 256-bit bus.
The R5 M230 has 320 shaders clocked at 855MHz, 20 texture units, and 4 ROPs. This GPU can support up to 4GB of GDDR5 memory at 1,000MHz over a 64-bit bus.
Users will be able to get the new Rx M200 series graphics cards in mobile systems from Alienware, Clevo, Lenovo, and MSI. Other manufactures should pick up the new GPUs soon as well. The new series is not terribly exciting being nearly identical to the existing HD 8000M counterparts, but it does update the lineup to AMD's new naming and branding scheme. Notably, should AMD release a Hawaii-based mobile GPU, it has not left itself much room as far as naming goes (R9 M295X?).

Tagged: Star Swarm, Oxide Games, Nitrous, Mantle, gaming, amd
Without having seen Frostbite run in Mantle there is still some supposition as to the true effect of the new technology; will it increase the performance of high end PCs and allow lower end ones to do things they cannot under DirectX? Engadget has a video of a different Mantle based engine called Nitrous, displaying a demo called Star Swarm which can display thousands of objects simultaneously on screen. In the video they switch to DirectX to show you how much the demo slows down and what effects need to be disabled to be able to make it perform as it does under Mantle. If this translates to real game performance Mantle could totally change RTS and most other types of games by a huge margin. Let's hope it arrives soon now that Kaveri is out!
"Some RTS games set the limit at 50-70 units, while others can cope with as many as 500, but a new game engine called Nitrous takes things up a level: It uses AMD's Mantle programming tool to speed up communication between the CPU and GPU, allowing up to 5,000 AI- or physics-driven objects (i.e., not mindless clones or animations) to be displayed onscreen at one time."

Not only are the first Kaveri reviews arriving today, the A10-7850K is up for sale on both NewEgg and Amazon and the A10-7700K is available on NewEgg. This new part, at 45W competes favourably with the previous 100W Trinity APU in most tests and when Ryan boosted it to 65W it gained a little more. The Steamroller cores have been updated but not in a way that has a huge effect on CPU performance, on the other hand the 384 SIMD units composing the GPU portion of this chip are quite impressive, 1080p gaming of current generation titles is possible on this chip and we haven't seen it's big brother with 512 SIMD units yet. In the Tech Report's review you can see that BF4 is playable on this chip and this is not the Mantle version optimized for AMD's new architecture. It is also a pity that Thief was unavailable to see just what TrueAudio is capable of. Unfortunately this chip will not find its home in gamers dream machines, that is simply not where AMD is targeting its CPUs. However, for SFF systems that need to be energy efficient and where a discrete GPU is to big to fit Kaveri will usher in a new level of performance.
"AMD's next-generation APU packs in a ton of innovation, including updated "Steamroller" CPU cores, GCN graphics, and advanced HSA features. But is it enough to restore AMD's competitiveness in desktop processors?"

The AMD Kaveri Architecture
Kaveri: AMD’s New Flagship Processor
How big is Kaveri? We already know the die size of it, but what kind of impact will it have on the marketplace? Has AMD chosen the right path by focusing on power consumption and HSA? Starting out an article with three questions in a row is a questionable tactic for any writer, but these are the things that first come to mind when considering a product the likes of Kaveri. I am hoping we can answer a few of these questions by the end of this article, but alas it seems as though the market will have the final say as to how successful this new architecture is.
AMD has been pursuing the “Future is Fusion” line for several years, but it can be argued that Kaveri is truly the first “Fusion” product that completes the overall vision for where AMD wants to go. The previous several generations of APUs were initially not all that integrated in a functional sense, but the complexity and completeness of that integration has been improved upon with each iteration. Kaveri takes this integration to the next step, and one which fulfills the promise of a truly heterogeneous computing solution. While AMD has the hardware available, we have yet to see if the software companies are willing to leverage the compute power afforded by a robust and programmable graphics unit powered by AMD’s GCN architecture.
(Editor's Note: The following two pages were written by our own Josh Walrath, dicsussing the technology and architecture of AMD Kaveri. Testing and performance analysis by Ryan Shrout starts on page 3.)
The first step in understanding Kaveri is taking a look at the process technology that AMD is using for this particular product. Since AMD divested itself of their manufacturing arm, they have had to rely on GLOBALFOUNDRIES to produce nearly all of their current CPUs and APUs. Bulldozer, Piledriver, Llano, Trinity, and Richland based parts were all produced on GF’s 32 nm PD-SOI process. The lower power APUs such as Brazos and Kabini have been produced by TSMC on their 40 nm and 28 nm processes respectively.
Kaveri will take a slightly different approach here. It will be produced by GLOBALFOUNDRIES, but it will forego the SOI and utilize a bulk silicon process. 28 nm HKMG is very common around the industry, but few pure play foundries were willing to tailor their process to the direct needs of AMD and the Kaveri product. GF was able to do such a thing. APUs are a different kind of animal when it comes to fabrication, primarily because the two disparate units require different characteristics to perform at the highest efficiency. As such, compromises had to be made.

Tagged: amd, vesa, dockport
One of AMD's pet projects will be seeing the light of day in the very near future, one that could put another nail in Thunderbolt's overpriced coffin. AMD in association with several other VESA members have developed an update to DisplayPort called DockPort that will provide USB 3.0 power and data over the cable at the same time it transmits up to 21.6 Gbps of DisplayPort Video. This will be of great usage when connecting your machine to a docking station, with one cable you get a lot of connectivity options and could also mean much smaller and less expensive docking stations are possible.
INTERNATIONAL CES, LAS VEGAS (7 January 2014) – The Video Electronics Standards Association (VESA®) announced today that DockPort will be added as an official extension to the existing DisplayPort standard. DockPort is an emerging technology that enables high-speed USB 3.0 data over the existing DisplayPort connector. Originally developed by AMD, Texas Instruments, and other VESA member companies, the DockPort extension will allow notebooks, tablets and other small form factor computers to aggregate the display, data and power interfaces into a single convenient connector.
Computers and other smart devices require high-speed I/O ports to share high-resolution video with external displays, high-bandwidth data with external storage and other peripherals, and power for battery charging. As notebooks and tablets become thinner and more portable, consumers want to combine these three common interfaces into a single port on their mobile device. With a single DisplayPort connection using the new DockPort extension and enhanced power capabilities under development, consumers will be able to attach their computers or tablets to a docking station and have instant, hassle-free access to a wide array of external resources.
“Consumers are happiest when they can personalize their electronics systems and reduce the number of cables they need to deal with at the same time,” explained Steve Belt, AMD’s corporate vice president of strategic alliances. “We identified DisplayPort as an ideal starting point and began collaborating with other industry leaders to create DockPort as an extension of DisplayPort’s capabilities. With just one inexpensive connector, users can now access power, a mouse, keyboard, external optical and hard disk drives, printers, gaming controller, and up to four external monitors. That’s a lot of capability from a single, standardized connector.”
AMD’s Discovery Tablet reference design, which utilizes DisplayPort with the DockPort extension to enable video, data and power over one connector, won two 2014 CES Innovation Awards.
“VESA’s decision to augment the popular DisplayPort standard with the single-connector capabilities of TI’s innovative DockPort controller is a win for end equipment designers and consumers,” said Wes Ray, systems and applications manager for Consumer and Computing Interface at Texas Instruments. “As an open standard, DockPort will be readily available for designers to implement, and more quickly deliver, the convenience of a single connection in devices such as tablets, notebooks, docking stations and dongles.”
DisplayPort is the world’s most advanced, high data rate video interface standard. It connects computers and other video sources to televisions and displays, while maintaining backward compatibility with VGA, DVI and HDMI. The global standard is backed by more than 200 technology leaders worldwide.
Designed to be robustly ‘future proof’ as well as backward compatible, DisplayPort allows a video source to drive up to four displays, and it is the only video interface that can support 4K UHD TVs and displays with deep color at 60 frames per second. DisplayPort with the DockPort extension will continue to be a royalty-free standard. DisplayPort-certified systems are available from every leading display manufacturer, and consumers purchase millions of DisplayPort products every year.
“Being a modern, high-speed, packet-based digital interface, DisplayPort was designed to be extensible while also providing backward compatibility,” said Craig Wiley, Sr. Director of Marketing for Parade Technologies, and Chair of the VESA Board of Directors. “Similar to Thunderbolt and MyDP, the new DockPort extension will utilize the flexibility of DisplayPort technology to create a single display, data, and, in the near future, power connector, while still being backward compatible with all other DisplayPort devices. We expect the DockPort feature will appear in main-stream products since its performance is tailored for standard connectors and passive cables.”

Confirming the results that Ryan and other sites have seen are the results of [H]ard|OCP's testing of two different retail R9 290X GPUs against a pair of press sample cards. Much as with Ryan's findings even using the newer Catalyst 13.11 Beta 5 driver, Quiet mode performance varies far more than Uber mode does but even Uber mode displays some differences between models. However they draw a slightly different conclusion based on their experiences, determining that the variance is not just a matter of press samples versus retail cards but a variance between any and all 290X GPUs. The complexity of this huge chip is such that the differences in manufacturing process and tolerances are to blame and some cards will simply be better than others. They also are disappointed by AMD's marketing team, citing that the key is 'With NVIDIA GTX 600 and 700 series the video cards are "running faster than advertised" and with AMD R9 290X the video card is running "slower than advertised."'
"The AMD Radeon R9 290X arrived recently with a high level of performance, and a high level of controversy. There have been reports of performance variance between Radeon R9 290X video cards. We have two purchased retail cards today with stock cooling that we will test and see if performance variances exist."

Tagged: water cooling, VisionTek, r9 290, liquid cooling, CES 2014, CES, amd
VisionTek unveiled a new custom liquid cooled graphics card based on AMD's R9 290 GPU. The CryoVenom R9 290 900675 card uses a custom engineered full cover EK water block that allows VisionTek to wring the full potential out of AMD's Hawaii GPU by overclocking it 24% over stock clockspeeds while running much cooler than the fan cooled reference cards.
As a refresher, the AMD R9 290 GPU at the heart of the new graphics card is based on AMD's latest Hawaii architecture and features 2,560 shaders, 160 texture units, and 64 ROPs. The GPU interfaces with 4GB of GDDR5 memory on a 512-bit bus. The reference R9 290 GPUs have a GPU clockspeed of 947 MHz and memory clockspeed of 1250 MHz (note the clockspeed problems of reference cards due to the coolers used).
The VisionTek card ditches a fan HSF in favor of a full cover waterblock that cools the GPU, memory, and VRMs. It has a nickel-plated copper base with an acrylic top. Water is channeled through a micro-fin array designed to cool the card without putting strain on low pressure pumps. A black anodized aluminum backplate adds support and passive (additional) VRM cooling to the graphics card. The CryoVenom maintains the two DL-DVI, one HDMI, and one DisplayPort video output connections of reference cards, however.
Going with a liquid cooler has allowed VisionTek to ratchet up the clockspeeds to an impressive 1,175 MHz for the GPU and 1,450 MHz for the memory. That is a respectable 24% and 16% increase over stock, respectively and is estimated to offer up to 38% better overall performance at those overclocked speeds. Perhaps even more impressive than the overclocks themselves is that VisionTek claims to be able to keep the card just under 52-degrees C under load which is a significant improvement over stock!
According to VisionTek, each Cryovenom R9 290 graphics card is custom build and put through a variety of burn in tests to ensure that it can operate at the rated overclocks and is free of water leaks when attached to a loop.
The liquid cooled cards have an MSRP of $550 and will be available shortly (the cards are currently out of stock on the VisionTek site). Here's hoping that VisionTek is able to keep the cards at MSRP, because even at a $150 premium over the MSRP of reference cards it would still be a good deal at a time when reference cards are being sold at prices well over MSRP.
