Microsoft has not been doing much to put out the fires in comment threads all over the internet. The latest flare-up involves hardware support with Windows 7 and 8.x. Currently unreleased architectures, such as Intel's Kaby Lake and AMD's Bristol Ridge, will only be supported on Windows 10. This is despite Windows 7 and Windows 8.x being supported until 2020 and 2023, respectively. Microsoft does not believe that they need to support older hardware, though.
This brings us to Skylake. These processors are out, but Microsoft considers them “transition” parts. Microsoft provided PC World with a list of devices that will be gjven Windows 7 and Windows 8.x drivers, which enable support until July 17, 2017. Beyond that date, only a handful of “most critical” updates will be provided until the official end of life.
I am not sure what the cut-off date for unsupported Skylake processors is, though; that is, Skylake processors that do not line up with Microsoft's list could be deprecated at any time. This is especially a problem for the ones that are potentially already sold.
As I hinted earlier, this will probably reinforce the opinion that Microsoft is doing something malicious with Windows 10. As Peter Bright of Ars Technica reports, Windows 10 does not exactly have an equivalent in the server space yet, which makes you wonder what that support cycle will be like. If they can continue to patch Skylake-based servers in Windows Server builds that are derived from Windows 7 and Windows 8.x, like Windows Server 2012 R2, then why are they unwilling to port those changes to the base operating system? If they will not patch current versions of Windows Server, because the Windows 10-derived version still isn't out yet, then what will happen with server farms, like Amazon Web Services, when Xeon v5s are suddenly incompatible with most Windows-based OS images? While this will, no doubt, be taken way out of context, there is room for legitimate commentary about this whole situation.
Of course, supporting new hardware on older operating systems can be difficult, and not just for Microsoft at that. Peter Bright also noted that Intel has a similar, spotty coverage of drivers, although that mostly applies to Windows Vista, which, while still in extended support for another year, doesn't have a significant base of users who are unwilling to switch. The point remains, though, that Microsoft could be doing a favor for their hardware vendor partners.
I'm not sure whether that would be less concerning, or more.
Whatever the reason, this seems like a very silly, stupid move on Microsoft's part, given the current landscape. Windows 10 can become a great operating system, but users need to decide that for themselves. When users are pushed, and an adequate reason is not provided, they will start to assume things. Chances are, it will not be in your favor. Some may put up with it, but others might continue to hold out on older platforms, maybe even including older hardware.
Other users may be able to get away with Windows 7 VMs on a Linux host.

The chip once known as Seattle has arrived from AMD, the Opteron A1100 Series which is built upon up to eight cores based on a 64-bit ARM Cortex-A57. The chips will have up to 4 MB of shared L2 cache and 8 MB L3 cache with an integrated dual-channel memory controller that supports up to 128 GB of DDR3 or DDR4 memory. For connectivity options you will have two 10Gb Ethernet ports, 8 lanes of PCIe 3.0 and up to 14 SATA3 devices.
As you can see above the TDPs range from 25W to 32W, perfect for power conscious data centres. The SoftIron Overdrive 3000 systems will use the new A1100 chips and AMD is working with Silver Lining Systems to integrate SLS’ fabric technology for interconnecting systems.
TechARP has posted a number of slides from AMD's presentation or you can head straight over to AMD to get the scoop. You won't see these chips on the desktop but new server chips are great news for AMD's bottom line in the coming year. They also speak well of AMD's continued innovations, using low powered and low cost 64-bit ARM chips, combined with their interconnect technologies opens up a new market for AMD.

Tagged: graphics drivers, amd
AMD's recent “Hotfix” drivers don't seem to mean what NVIDIA's does. In the Green Team's case, they usually fix one or two issues that slipped past QA. While they likely won't break anything, they are probably a bad idea to install if you're not experiencing the listed problems. The changelog on AMD's drivers are significantly longer with a list of known issues that is roughly the same size.
So should you install it? That depends. It's a little less cut-and-dry than NVIDIA's hotfixes, which are only useful for a handful of people. It sounds like the worst known issue is “Game stuttering may be experienced when running two Radeon R9 295X2 graphics cards in CrossFire mode” and “Display corruption may occur on multiple display systems when it has been running idle for some time.” The latter would affect me greatly, because I run four displays and basically never sleep or shutdown (except for updates). On the other hand, it fixes a variety of crash, hang, and flicker issues.
Check it out. If it sounds good, then pick it up. Otherwise, wait for the next Beta or WHQL driver.

According to a report published by CPU World, a pair of unreleased AMD Athlon X4 processors appeared in a supported CPU list on Gigabyte's website (since removed) long enough to give away some information about these new FM2+ models.
Image credit: CPU World
The CPUs in question are the Athlon X4 835 and Athlon X4 845, 65W quad-core parts that are both based on AMD's Excavator core, according to CPU World. The part numbers are AD835XACI43KA and AD845XACI43KA, which the CPU World report interprets:
"The 'I43' letters and digits in the part number signify Socket FM2+, 4 CPU cores, and 1 MB L2 cache per module, or 2MB in total. The last two letters 'KA' confirm that the CPUs are based on Carrizo design."
The report further states that the Athlon X4 835 will operate at 3.1 GHz, with 3.5 GHz for the X4 845. No Turbo Core frequency information is known for these parts.

Tagged: radeon, r9 nano, R9 Fury X, price cut, press release, amd
AMD has announced a price cut for the Radeon R9 Nano, which will now have a suggested price of $499, a $150 drop from the original $649 MSRP.
VideoCardz had the story this morning, quoting the official press release from AMD:
"This past September, the AMD Radeon™ R9 Nano graphics card launched to rave reviews, claiming the title of the world’s fastest and most power efficient Mini ITX gaming card, powered by the world’s most advanced and innovative GPU with on-chip High-Bandwidth Memory (HBM) for incredible 4K gaming performance. There was nothing like it ever seen before, and today, it remains in a class of its own, delivering smooth, true-to-life, premium 4K and VR gaming in a small form factor PC.
At a peak power of 175W and in a 6-inch form factor, it drives levels of performance that are on par with larger, more power-hungry GPUs from competitors, and blows away Mini ITX competitors with up to 30 percent better performance than the GTX 970 Mini ITX.
As of today, 11 January, this small card will have an even bigger impact on gamers around the world as AMD announces a change in the AMD Radeon™ R9 Nano graphics card’s SEP from $649 to $499. At the new price, the AMD Radeon™ R9 Nano graphics card will be more accessible than ever before, delivering incredible performance and leading technologies, with unbelievable efficiency in an astoundingly small form factor that puts it in a class all of its own."
The R9 Nano (reviewed here) had been the most interesting GPU released in 2015 to the team at PC Perspective. It was a compelling product for its tiny size, great performance, and high power efficiency, but the dialogue here probably mirrored that of a lot of potential buyers; for the price of a Fury X, did it make sense to buy the Nano? It was all going to depend on need, but very few enclosures on the market do not support a full-length GPU, as we discovered when testing out small R9 Nano builds.
Now that the price will move down $150 it becomes an easier choice: $499 will buy you a full R9 Fury X core for $150 less. The performance of a Fury X is only a few percentage points higher than the slighly lower-clocked Nano, so you're now getting most of the way there for much less. We have seen some R9 Fury X cards selling for $599, but even at $100 more would you buy the Fury X over a Nano? If nothing else the lower price makes the conversation a lot more interesting.

Zotac had several new ZBOX small form-factor PCs on display at CES, and among these was a new E series system featuring a pairing of an Intel Skylake i3 with an AMD Radeon R9 GPU.
The Radeon in question is the R9 M365X, a discrete mobile part with 640 stream processors, up to 925 MHz core clock, and 2 GB of dedicated 128-bit GDDR5 memory running at up to 1125 MHz (72 GB/s max bandwidth). This is running on a very capable platform powered by a 6th-gen Intel Core i3-6100T, a 35W 2 core/4 thread part running at 3.20 GHz.
Here is a rundown of the specifications:
- Processor: Intel Core i3-6100T (Skylake) dual-core, 3.20 GHz
- Graphics: AMD Radeon R9 M365X with 2 GB GDDR5
- Memory: 2x DDR3L-1600 SoDIMM slots
- Storage: 2.5-inch SATA 6.0 Gbps; M.2 SSD slot
- USB: 2x USB 3.0; USB 3.0 Type-C
- Networking: 2x Gigabit LAN; 802.11ac Wi-Fi; Bluetooth 4.0
- Display output: 3x DisplayPort
Good to see a discrete AMD GPU option in one of these small form-factor ZBOX units, as previous E-series models offered only NVIDIA or Intel solutions. Unfortunately no release date or price was announced.

AMD seems to be starting off 2016 right. This is the year that they intend to switch to the Zen microarchitecture, and hopefully reclaim a profitable CPU market-share. While that's later in the year, they showed off a new stock cooler that will be bundled with upcoming processors. We don't have a press release or announcement for it, but they did publish a video to their Red Team fan community and they discussed it with attendees of the show.
The new cooler, called the Wraith, is significantly larger than their previous stock heatsink. It is rated at 125W, up from the previous offering's 95W. This dissipation wattage might allow some overclocking room, depending on the chosen TDP at launch, while providing lower noise at stock voltage and frequency. The fan is now constant speed, so it shouldn't whine under load. It might have also allowed them to tune the fan for its RPM, too.
Speaking of lower noise, the aforementioned video shows a dramatic reduction in that area. We're force to trust their recording and frequency-distribution graph. If accurate, the noise appears to be much lower and the energy is spread out over many frequencies.
No clue when it will launch, though.

At its suite at CES this year, AMD was showing off a couple of new technologies. First, we got to see the upcoming Polaris GPU architecture in action running Star Wars Battlefront with some power meters hooked up. This is a similar demo to what I saw in Sonoma back in December, and it compares an upcoming Polaris GPU against the NVIDIA GTX 950. The result: total system power of just 86 watts on the AMD GPU and over 150 watts on the NVIDIA GPU.
Another new development from AMD on the FreeSync side of things was HDMI integration. The company took time at CES to showcase a pair of new HDMI-enabled monitors working with FreeSync variable refresh rate technology.

Tagged: crimson, amd
That's right ladies and germs, not even a full week into 2016 and AMD has a new driver for you, or at least a hotfix version of Crimson 16.1. If you are playing Elite:Dangerous, Fallout 4 or Just Cause 3 there are a number of fixes to known issues from the original 12.1 which will make it worth picking up as soon as you can. So far in testing, game profiles do seem to last through an update so if you did take advantage of the game specific overclocking settings you should not lose all your hard work.
They have also included fixes specific to VSR, odd HDMI setups and flickering in Freesync displays. As always there are a few bugs still to be ironed out, which is why you should fill in the bug reporting tool at the bottom of the driver page instead of just throwing things at random passersby ... as fun and entertaining as that may be.
