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.

CES 2014: AMD Supported in SteamOS "Out of the Box". Catalyst 13.11 Beta 9.9 in SteamOS Public Stable Branch
Subject: General Tech | January 9, 2014 - 05:18 PM | Scott Michaud
Tagged: SteamOS, CES 2014, CES, amd
The Steam platform prides itself on benefiting from the many billions of dollars spent by the PC industry in-fighting. Two-and-a-half of the consoles seem to realize that they cannot keep up with the constant churn as the PC trots along its exponential curve. They, now more than ever, align themselves with our industry instead of running their own R&D treadmill. Each of these companies now license the efforts of AMD.
Simply put, consoles struggle because their business model plans on a big loss followed by a few years of rest to have a chance of breaking even. Slow and steady wins the race.
SteamOS is a console that, instead of seeing how much it can justify locking down, goes the other way. So, when the prototype units were announced, it felt really weird to see a fairly wide selection of components... from a set of Intel processors and NVIDIA discrete graphics cards. AMD and Intel were a bit late for one reason or another.
But only just a bit. An updated AMD graphics driver, the Catalyst 13.11 Beta 9.9, has just been integrated into the SteamOS public stable branch. This driver is expected to fix tearing, overlay performance, in-game performance, and "malfunctioning return to desktop".
The driver will also be released on AMD.com soon.

The MSI Lightning series of graphics cards continues to be one of the best high end enthusiast lines available as we have seen with our reviews of the MSI GeForce GTX 780 Lightning and the R7970 Lightning. At CES this week in Las Vegas the company was showcasing the upcoming card in the series based on the latest AMD Hawaii GPU.
The MSI R9 290X Lightning features an updated triple cooler design and heat pipe cooler that appears to be truly impressive. If the weight of the card is any indication, this GPU should be running considerably cooler than most of the competition.
MSI has included a dual BIOS option, updated Military Class 4 components and hardware but be prepared to sacrifice three slots of your motherboard to this monster. Power requirements are interesting with a pair of 8-pin power connectors and a single 6-pin connector, though the 6-pin is going to optional.
The power of the card still comes from AMD's latest R9 290X Hawaii GPU, so you can be sure you'll have enough gaming power for just about any situation. We implored MSI to make sure that the overclocks of this card, probably in the 1050-1100 MHz range, are maintained consistently through extended game play to avoid any awkward variance discussions.

Tagged: triple fans, R9 290X, r9 290, powercolor, liquid cooling, cooling, CES 2014, amd
The nice folks at PowerColor were foolish enough to invite us into their suite full of video cards. Unhappily, we were unable to abscond with a few items that we will list here. PowerColor has a smaller US presence than other manufacturers, but they are not afraid to experiment with unique cooling solutions for their cards.
A sharp looking card that is remarkably heavy.
Cooling is provided by EKWB.
In their suite they were showing off two new products based on the AMD R9 290X chips. The first was actually released back in December, 2013. This is the liquid cooling version of the AMD R9 290X. This little number comes in at a hefty $799. When we think about this price, it really is not that out of line. It features a very high end liquid cooling block that is extremely heavy and well built. The PCB looks like it mimics the reference design, but the cooling is certainly the unique aspect of this card. Again, this card is extremely heavy and well built.
Three fans are too much!
The display outputs are the same as the reference design, which is not a bad thing.
The second card is probably much more interesting to most users. This is a new cooling solution from PowerColor that attaches to the AMD R9 290X. The PCS+ cooler features three fans and is over two slots wide (we can joke about it being 2.5 slots wide, but I doubt anyone can use that extra half slot that is left over). PCS+ stands for Professional Cooling Systems. The board again looks like it is based on the reference PCB, but the cooler is really where the magic lies. This particular product should be able to compete with the other 3rd party coolers that we have seen applied to this particular chip from AMD. As such, it should be able to not only keep the clockspeed at a steady state throughout testing/gaming, but it should also allow a measure of overclocking to be applied.
The back is protected/supported by a large and stiff plate. Cooling holes help maximize performance.
This card will be offered at $679 US and will be available on January 15. The amount of units shipped will likely be fairly small, so keep a good eye out. AMD is ultimately in charge of providing partners with chips to integrate into their respective products, and so far I think those numbers have been a little bit more limited than hoped. It also doesn’t help that the market price has been inflated by all the coin miners that have been purchasing up the latest GCN based AMD cards for the past several months.
There is no denying that this is a large cooler. Hopefully cooling performance will match or exced that of products Ryan has already reviewed.
We also expect to see the R9 290 version of this card around the same timeframe. This is supposed to be released around the same time as the bigger, more expensive R9 290X. There should be more PowerColor content at PCPer over the next few months, so please stay tuned!

Tagged: tom petersen, nvidia, g-sync, free sync, CES 2014, amd
AMD's free sync has been getting a lot of well deserved attention at this years CES, Ryan had a chance to see it in action if you haven't checked out his look at AMD's under reported and under utilized feature. AMD missed an opportunity with this technology which NVIDIA picked up on with their G-Sync. NVIDIA has responded to The Tech Report's comments from yesterday, Tom Petersen stated that while free sync may be an alternative on laptops, desktop displays are a different beast. They utilize different connections and there is generally a scaler chip between the GPU and the display. Read his full comments here.
"AMD demoed its "free sync" alternative to G-Sync on laptops. Desktop displays are different, Nvidia says, and they may not support the variable refresh rate tech behind AMD's solution—at least not yet."

DisplayPort to Save the Day?
During an impromptu meeting with AMD this week, the company's Corporate Vice President for Visual Computing, Raja Koduri, presented me with an interesting demonstration of a technology that allowed the refresh rate of a display on a Toshiba notebook to perfectly match with the render rate of the game demo being shown. The result was an image that was smooth and with no tearing effects. If that sounds familiar, it should. NVIDIA's G-Sync was announced in November of last year and does just that for desktop systems and PC gamers.
Since that November unveiling, I knew that AMD would need to respond in some way. The company had basically been silent since learning of NVIDIA's release but that changed for me today and the information discussed is quite extraordinary. AMD is jokingly calling the technology demonstration "FreeSync".
Variable refresh rates as discussed by NVIDIA.
During the demonstration AMD's Koduri had two identical systems side by side based on a Kabini APU . Both were running a basic graphics demo of a rotating windmill. One was a standard software configuration while the other model had a modified driver that communicated with the panel to enable variable refresh rates. As you likely know from our various discussions about variable refresh rates an G-Sync technology from NVIDIA, this setup results in a much better gaming experience as it produces smoother animation on the screen without the horizontal tearing associated with v-sync disabled.
Obviously AMD wasn't using the same controller module that NVIDIA is using on its current G-Sync displays, several of which were announced this week at CES. Instead, the internal connection on the Toshiba notebook was the key factor: Embedded Display Port (eDP) apparently has a feature to support variable refresh rates on LCD panels. This feature was included for power savings on mobile and integrated devices as refreshing the screen without new content can be a waste of valuable battery resources. But, for performance and gaming considerations, this feature can be used to initiate a variable refresh rate meant to smooth out game play, as AMD's Koduri said.
