Linux support for AMD's GPUs has not been progressing at the pace many users would like, though it is improving over time but that is not the same with their APUs.  Phoronix just tested the A10-7800 and A6-7400K on Ubuntu 14.04 with kernel 3.13 and the latest Catalyst 14.6 Beta.  This preview just covers the raw performance, you can expect to see more published in the near future that will cover new features such as the configurable TDP which exists on these chips.  The tests show that the new 7800 can keep pace with the previous 7850K and while the A6-7400K is certainly slower it will be able to handle a Linux machine with relatively light duties.  You can see the numbers here.

"At the end of July AMD launched new Kaveri APU models: the A10-7800, A8-7600, and A6-7400K. AMD graciously sent over review samples on their A10-7800 and A6-7400K Kaveri APUs, which we've been benchmarking and have some of the initial Linux performance results to share today."

In a branding move that has no possibility of causing confusion, AMD has announce the name of their new SSD line and it seems that the next Radeon R7 240 you buy might be a GPU or then again it might not be.  Brand confusion aside, the drives will use 19nm Toshiba NAND fabbed at SanDisk and are predicted to perform similar to other drives with the same NAND, reads of 550MBps and 530MBps write.  However as we well know the key to performance lies in the controller and the number of channels so it will be interesting to see the first benchmarks.  As The Inquirer points out this could lead to the release of AMD branded machines, containing AMD made APU, RAM, SSD and discrete GPU.

ASUS Republic of Gamers Announces the Crossblade Ranger

Subject: Motherboards | August 7, 2014 - 02:14 PM |
Tagged: SupremeFX 2014, LANGuard, KeyBot, GameFirst III, FM2+, crossblade ranger, ASUS ROG, asus, amd

ASUS Republic of Gamers have just released their first FM2+ board, the Crossblade Ranger which should be available for ~$160 in the next few days, a perfect base for the A10-7800 and A6-7400K which Josh just reviewed.  There is a host of features on this board, from an updated SupremeFX 2014 audio system to eliminate interference and adjust impedance to the LANGuard and GameFirst III networking enhancements.  KeyBot is also new, it allows you to program macros on any USB keyboard regardless of the capabilities of the keyboard itself.  Check out the full release for a breakdown of the features.

unnamed1.jpg

Fremont, CA (6th August, 2014) - ASUS Republic of Gamers (ROG) today announced the Crossblade Ranger, the first AMD FM2+ motherboard to carry the revered ROG brand name, packed with game-boosting features for an AMD-based gaming powerhouse that is beyond compare. The Crossblade Ranger’s core benefits include the best gaming networking with Intel Gigabit Ethernet, the best gaming audio from SupremeFX 2014, the best gaming interface with KeyBot and the best gaming performance.

Best gaming networking
The Crossblade Ranger is fitted with state-of-the-art Intel Gigabit Ethernet that delivers better throughput and lower power consumption than competing solutions from other vendors.

The new motherboard’s networking capabilities additionally benefit from ROG-exclusive GameFirst III technology for optimal online gameplay. This advanced network-optimization software assigns top priority to game-data packets, allocating them more bandwidth to ensure the best online-gaming experience and clear, stutter-free online team-chat — all controlled with ROG’s usual intuitive flair.

These features are coupled with LANGuard Ethernet socket technology. LANGuard works by employing advanced filtering components with low impedance capacitors to reduce noise and improve throughput and also includes ESD and surge-protection to prevent damage from lightning strikes and static-electricity discharges.

Best gaming audio
Immersive audio is essential for gaming, so the Crossblade Ranger is engineered with SupremeFX 2014. At its core the SupremeFX 2014 solution uses PCB isolation techniques to minimize electromagnetic interference (EMI) and premium ELNA audio capacitors to provide precise 7.1 channel audio that’s on par with the best soundcards.

SupremeFX 2014 features dedicated hardware for features such as Sonic SenseAmp and Sonic SoundStage. Sonic SenseAmp automatically detects analog-audio front-panel (AAFP) headphone impedance and adjusts the amp gain to provide the best volume control range - taking the guesswork and hassle out of setting gain manually.

Sonic Soundstage is a hardware based solution that features preset audio profiles for a variety of gaming genres. First-person shooter (FPS), racing, combat and sports games presets are available via an onboard hardware switch or via the included (Windows) driver package. The benefit of including an onboard hardware switch is that the Sonic Soundstage presets can be applied without needing a driver – so works with any operating system. For Windows users, the presets are fully customizable via software, allowing one to tailor sound to personal preference.

SupremeFX 2014 also includes additional software features to provide a competitive gaming edge and improve immersion.

Designed for first-person shooters (FPS), Sonic Radar II displays a stealthy overlay that shows what opponents and teammates are up to. Players see the precise direction and origin of in-game sounds such as gunshots, footsteps and call-outs, enabling them to hone enemy-pinpointing skills.

Sonic Studio can be used to create virtual surround modes for stereo headsets, provides EQ controls to tune various parts of the audio spectrum and includes noise reduction algorithms for microphones – this all adds up to make SupremeFX 2014 the complete gaming audio solution.

Best gaming interface
The Crossblade Ranger includes KeyBot, a clever tool that lets users instantly ‘upgrade’ an existing keyboard simply by attaching it to the dedicated USB socket.

Once connected, the KeyBot microprocessor is activated and the user is able to use their current keyboard to control multimedia playback, launch favorite applications or assign macros to specific keys —perfect for automating complicated in-game key sequences without the need for an expensive gaming keyboard.

Best gaming performance and experience
Being an ROG motherboard, the Crossblade Ranger is infused with core ROG DNA.

Overclocking Features
ROG’s Auto-Tuning technology enables the Crossblade Ranger to unleash the true power of AMD APUs with just few mouse clicks. Thanks to the TPU microprocessor (Turbo Processing Unit), the Auto-Tuning routine applies a CPU overclock without need to enter UEFI - perfect for users that are new to the platform.

For users that prefer manual control, the TPU microprocessor and bundled Turbo-V application allows real-time voltage adjustments within the Windows operating system to simplify the process of overclocking a system. Naturally, the ROG UEFI is also chock-full of overclocking functions that help squeeze every ounce of performance from the AMD FM2+ platform.

Fan Controls
To keep things cool and quiet, we’ve included five onboard fan headers – each with PWM (4-pin) or DC (3-pin) control. Extensive fan control options are available within UEFI or the automated Fan Xpert 3 calibration utility. Using either method, anyone can customize fan profiles in order to maximize cooling efficiency and eliminate unnecessary fan noise. The level of control on offer here sets a new standard for the FM2+ platform and completely negates the need for using a dedicated and expensive fan controller.

ROG Accessories
The Crossblade Ranger is also compatible with the ROG Front Base dual-bay gaming panel. The ROG Front Base enables one-click performance boosting, fan-controls, shielded front audio input/outputs, audio profile selection, volume control and real-time system monitoring to provide everything a gamer needs within a single unit.

Filling the Product Gaps

In the first several years of my PCPer employment, I typically handled most of the AMD CPU refreshes.  These were rather standard affairs that involved small jumps in clockspeed and performance.  These happened every 6 to 8 months, with the bigger architectural shifts happening some years apart.  We are finally seeing a new refresh of the AMD APU parts after the initial release of Kaveri to the world at the beginning of this year.  This update is different.  Unlike previous years, there are no faster parts than the already available A10-7850K.

a10_7800_01.png

This refresh deals with fleshing out the rest of the Kaveri lineup with products that address different TDPs, markets, and prices.  The A10-7850K is still the king when it comes to performance on the FM2+ socket (as long as users do not pay attention to the faster CPU performance of the A10-6800K).  The initial launch in January also featured another part that never became available until now; the A8-7600 was supposed to be available some months ago, but is only making it to market now.  The 7600 part was unique in that it had a configurable TDP that went from 65 watts down to 45 watts.  The 7850K on the other hand was configurable from 95 watts down to 65 watts.

a10_7800_02.png

So what are we seeing today?  AMD is releasing three parts to address the lower power markets that AMD hopes to expand their reach into.  The A8-7600 was again detailed back in January, but never released until recently.  The other two parts are brand new.  The A10-7800 is a 65 watt TDP part with a cTDP that goes down to 45 watts.  The other new chip is the A6-7600K which is unlocked, has a configurable TDP, and looks to compete directly with Intel’s recently released 20 year Anniversary Pentium G3258.

Tagged: amd, seattle, developer, arm, opteron a1100, Cortex A57

AMD has been teasing us with Seattle, their first ARM based CPU which Josh described back in May after AMD's presentation.  The AMD Opteron A1100 series will come in 4 and 8 core versions with each core being a Cortex A57 that has up to 4MB of shared L2 and 8MB of shared L3 cache, support for DDR3 or DDR4, 8 lanes of PCIe 3.0, up to 8 SATA3 ports and two 10Gb Ethernet ports.  The newly announced Dev Kit will ship with a 4 core version and it can be yours for a mere $3000 if your application is accepted by AMD.  It will be very interesting to see how these are integrated into existing server rooms and applications though it is a pity we will have to wait for HSA support.  Check out more at The Inquirer.

AMD Releases FreeSync Information as a FAQ

Subject: General Tech, Graphics Cards, Displays | July 29, 2014 - 09:02 PM |
Tagged: vesa, nvidia, g-sync, freesync, DisplayPort, amd

Dynamic refresh rates have two main purposes: save power by only forcing the monitor to refresh when a new frame is available, and increase animation smoothness by synchronizing to draw rates (rather than "catching the next bus" at 16.67ms, on the 16.67ms, for 60 Hz monitors). Mobile devices prefer the former, while PC gamers are interested in the latter.

Obviously, the video camera nullifies the effect.

NVIDIA was first to make this public with G-Sync. AMD responded with FreeSync, starting with a proposal that was later ratified by VESA as DisplayPort Adaptive-Sync. AMD, then, took up "Project FreeSync" as an AMD "hardware/software solution" to make use of DisplayPort Adaptive-Sync in a way that benefits PC gamers.

Today's news is that AMD has just released an FAQ which explains the standard much more thoroughly than they have in the past. For instance, it clarifies the distinction between DisplayPort Adaptive-Sync and Project FreeSync. Prior to the FAQ, I thought that FreeSync became DisplayPort Adaptive-Sync, and that was that. Now, it is sounding a bit more proprietary, just built upon an open, VESA standard.

If interested, check out the FAQ at AMD's website.
