AMD gets a new SVP of Global Operations

Subject: General Tech | December 16, 2014 - 02:57 PM |
Tagged: amd

James Clifford started his career at Unisys Corporation, working his way up to VP & GM of Orange County Operations during over 20 years at that company, essentially handling their global sourcing and foundry needs.  From there he moved to Qualcomm and again spent quite a bit of time, almost 18 years, serving in a variety of leadership roles and ending his time there as the Senior VP & GM of Operations.  He then headed to RF Micro Devices, Inc for a brief time before joining AMD today in the role of Senior VP of Global Operations and reporting directly to Dr. Lisa Su according to the story at DigiTimes.  This is an exciting move for AMD, hopefully his significant experience in the semiconductor industry will help move AMD forward over the coming years and help them regain their share of the marketplace.

AMD Omega is no longer in Alpha

Subject: Graphics Cards | December 9, 2014 - 03:08 PM |
Tagged: amd, catalyst, driver, omega

With AMD's new leader and restructuring comes a new type of driver update.  The Omega driver is intended to provide a large number of new features as well as performance updates once a year.  It does not replace the current cycle of Beta and WHQL driver updates and the next driver update will incorporate all of the changes from the Omega driver plus the new bug fixes or updates that the driver was released to address.

Many sites including The Tech Report have had at least a small amount of time to test the new driver and have not seen much in the way of installation issues, or unfortunately performance improvements on systems not using an AMD APU.  As more time for testing elapses and more reviews come out we may see improvements on low end systems but for now the higher end machines show little to no improvement on raw FPS rates.  Keep your eyes peeled for an update once we have had time to test the change on frame pacing results, which are far more important than just increasing your FPS. 

The main reason to be excited about this release, it is the long list of new features, from a DSR-like feature called Virtual Super Resolution which allows you to increase the resolution of your monitor although for now 4K super resolution is limited to the R285 as it is the only AMD Tonga card on the market at the moment.  Along with the release of the Omega driver comes news about Freesync displays, another feature enabled in the new driver and their availability; we have a release date of January or February with a 4K model arriving in March.

Check out the links to The Tech Report and below to read the full list of new features that this driver brings and don't forget to click on Ryan's article as well.

"AMD has introduced what may be its biggest graphics driver release ever, with more than 20 new features, 400 bug fixes, and some miscellaneous performance improvements."

New Features

There are smart people that work at AMD. A quick look at the company's products, including the APU lineup as well as the discrete GPU fields, clearly indicates a lineup of talent in engineering, design, marketing and business. It's not perfect of course, and very few companies can claim to be, but the strengths of AMD are there and easily discernible to those of us on the outside looking in with the correct vision.

Because AMD has smart people working hard to improve the company, they are also aware of its shortcomings. For many years now, the thorn of GPU software has been sticking in AMD's side, tarnishing the name of Radeon and the products it releases. Even though the Catalyst graphics driver has improved substantially year after year, the truth is that NVIDIA's driver team has been keeping ahead of AMD consistently in basically all regards: features, driver installation, driver stability, performance improvements over time.

slide01.jpg

If knowing is half the battle, acting on that knowledge is at least another 49%. AMD is hoping to address driver concerns now and into the future with the release of the Catalyst Omega driver. This driver sets itself apart from previous releases in several different ways, starting with a host of new features, some incremental performance improvements and a drastically amped up testing and validation process.

slide02.jpg

AMD considers this a "special edition" driver and is something that they plan to repeat on a yearly basis. That note in itself is an interesting point - is that often enough to really change the experience and perception of the Catalyst driver program going forward? Though AMD does include some specific numbers of tested cases for its validation of the Omega driver (441,000+ automated test runs, 11,000+ manual test runs) we don't have side by side data from NVIDIA to compare it to. If AMD is only doing a roundup of testing like this once a year, but NVIDIA does it more often, then AMD might soon find itself back in the same position it has been.

UPDATE: There has been some confusion based on this story that I want to correct. AMD informed us that it is still planning on releasing other drivers throughout the year that will address performance updates for specific games and bug fixes for applications and titles released between today and the pending update for the next "special edition." AMD is NOT saying that they will only have a driver drop once a year.

But before we worry about what's going to happen in the future, let's look into what AMD has changed and added to the new Catalyst Omega driver released today.

Awake Yet? Good! Optimizing Inverse Trig for AMD GPUs.

Subject: General Tech, Graphics Cards | December 2, 2014 - 03:11 AM |
Tagged: amd, GCN, dice, frostbite

Inverse trigonometric functions are difficult to compute. Their use is often avoided like the plague. If, however, the value is absolutely necessary, it will probably be solved by approximations or, if possible, replacing them with easier functions by clever use of trig identities.

If you want to see how the experts approach this problem, then Sébastien Lagarde, a senior developer of the Frostbite engine at DICE, goes into detail with a blog post. By detail, I mean you will see some GPU assembly being stepped through by the end of it. What makes this particularly interesting is the diagrams at the end, showing what each method outputs as represented by the shading of a sphere.

If you are feeling brave, take a look.

Far Cry 4 uses the same engine as the previous game, Dunia Engine 2, albeit updated and modified for the new features GPUs can handle, especially NVIDIA's Gameworks features.  This gives you some idea of how your system will handle the game but for a definitive look at performance just check out this review at [H]ard|OCP.  For their testing they used the GeForce 344.75 WHQL on their GTX 980 and 970 and the Catalyst 14.11.2 Beta for the R9 290X and 290.  On the Ultra preset running at 1440p the performance differences between the AMD and NVIDIA cards were negligible, once they started testing the new features such as the enhanced godrays and AA options there were some significant differences which you should educate yourself about.  It is worth noting that even two GTX 980s in SLI at 3600x1920 are not capable of handling 8x MSAA, thankfully SMAA is supported in the game.

"Far Cry 4 is here, and we take an early look at how current video cards stack up in performance, and which quality settings are graphically demanding. We will also look at some image quality comparisons and talk about the state of this game at launch. Will it measure up to Far Cry 3 in terms of graphic fidelity?"

AMD Announces Carrizo and Carrizo-L SOCs

Subject: Processors | November 20, 2014 - 01:31 PM |
Tagged: amd, APU, carrizo, Carrizo-L, Kaveri, Excavator, Steamroller, SoC, Intel, mobile

AMD has certainly gone about doing things in a slightly different manner than we are used to.  Today they announced their two latest APUs which will begin shipping in the first half of 2015.  These APUs are running at AMD and are being validated as we speak.  AMD did not release many details on these products, but what we do know is pretty interesting.

Carrizo is based on the latest iteration of AMD’s CPU technology.  Excavator is the codename for these latest CPU cores, and they promise to be smaller and more efficient than the previous Steamroller core which powers the latest Kaveri based APUs.  Carrizo-L is the lower power variant which will be based on the Puma+ core.  The current Beema APU is based on the Puma architecture.

AMD_Mobility_Roadmap_2015.jpg

Roadmaps show that the Carrizo APUs will be 28 nm products, presumably fabricated by GLOBALFOUNDRIES.  Many were hoping that AMD would make the jump to 20 nm with this generation of products, but that does not seem to be the case.  This is not surprising due to the limitations of that particular process when dealing with large designs that require a lot of current.  AMD will likely be pushing for 16 nm FinFET for the generation of products after Carrizo.

The big Carrizo supposedly has a next generation GCN unit.  My guess here is that it will use the same design as we saw with the R9 285.  That particular product is a next generation unit that has improved efficiency.  AMD did not release how many GCN cores will be present in Carizzo, but it will be very similar to what we see now with Kaveri.  Carrizo-L will use the same GCN units as the previous generation Beema based products.

carrizo_01.png

I believe AMD has spent a lot more time hand tuning Excavator instead of relying on a lot of automated place and route.  This should allow them to retain much of the performance of the part, all the while cutting down on transistor count dramatically.  Some rumors that I have seen point to each Excavator module being 40% smaller than Steamroller.  I am not entirely sure they have achieved that type of improvement, but more hand layout does typically mean greater efficiency and less waste.  The downside to hand layout is that it is extremely time and manpower intensive.  Intel can afford this type of design while AMD has to rely more on automated place and route.

Carrizo will be the first HSA 1.0 compliant SOC.  It is in fact an SOC as it integrates the southbridge functions that previously had been handled by external chips like the A88X that supports the current Kaveri desktop APUs.  Carrizo and Carrizo-L will also share the same infrastructure.  This means that motherboards that these APUs will be soldered onto are interchangeable.  One motherboard from the partner OEMs will be able to address multiple markets that will see products range from 4 watts TDP up to 35 watts.

Finally, both APUs feature the security processor that allows them access to the ARM TrustZone technology.  This is a very small ARM processor that handles the secure boot partition and handles the security requests.  This puts AMD on par with Intel and their secure computing solution (vPro).

carrizo_02.png

These products will be aimed only at the mobile market.  So far AMD has not announced Carrizo for the desktop market, but when they do I would imagine that they will hit a max TDP of around 65 watts.  AMD claims that Carrizo is one of the biggest jumps for them in terms of power efficiency.  A lot of different pieces of technology have all come together with this product to make them more competitive with Intel and their process advantage.  Time will tell if this is the case, but for now AMD is staying relevant and pushing their product releases so that they are more consistently ontime.

Samsung Announces First FreeSync UHD Monitors

We have been teased for the past few months about when we would see the first implementations of AMD’s FreeSync technology, but now we finally have some concrete news about who will actually be producing these products.

Samsung has announced that they will be introducing the world’s first FreeSync enabled Ultra HD monitors.  The first models to include this feature will be the updated UD590 and the new UE850.  These will be introduced to the market in March of 2015.  The current UD590 monitor is a 28” unit with 3845x2160 resolution with up to 1 billion colors.  This looks to be one of those advanced TN panels that are selling from $500 to $900, depending on the model.

Samsung-UD590.jpg

AMD had promised some hand’s on time for journalists by the end of this year, and shipping products in the first half of next year.  It seems that Samsung is the first to jump on the wagon.  We would imagine that others will be offering the technology.  In theory this technology offers many of the same benefits of NVIDIA’s G-SYNC, but it does not require the same level of hardware.  I can imagine that we will be seeing some interesting comparisons next year with shipping hardware and how Free-Sync stacks up to G-SYNC.

Joe Chan, Vice President of Samsung Electronics Southeast Asia Headquarters commented, “We are very pleased to adopt AMD FreeSync technology to our 2015 Samsung Electronics Visual Display division’s UHD monitor roadmap, which fully supports open standards.  With this technology, we believe users including gamers will be able to enjoy their videos and games to be played with smoother frame display without stuttering or tearing on their monitors.”
