AMD Goes After Intel’s Skylake With Bristol Ridge
Comments Off on AMD Goes After Intel’s Skylake With Bristol Ridge
AMD has revealed the firm’s seventh-generation system-on-a-chip accelerated processing units (APUs).
Bristol Ridge and Stoney Ridge sound a little like locations in a Somerset version of Game of Thrones, but they both feature AMD’s Excavator x86 processor cores and Radeon R7 graphics, which AMD sees powering e-sports gaming on laptops.
Bristol Ridge is the more powerful of the two coming in 35W and 15W versions of AMD FX, A12 and A10 processors, offering up to 3.7GHz of processing power. The former two processors are paired with up to eight Graphics Core Next (GCN) cores in the R7 to provide a decent pool of graphics processing power.
Stoney Bridge offers less in the way of processor power, topping out at 3.5GHz, and versions include 15W A9, A6 and E2 processor configurations coupled with lower powered graphics accelerators.
AMD claimed that the new APUs offer a 50 per cent hike in performance over the previous generation Carrizo APUs. However, this rise is over APUs from the early part of Carrizo’s lifecycle, so performance gains over the most recent Carrizo APUs are likely to be 10 to 20 per cent.
AMD also said that its silicon is faster than rival chips from Intel, including the i3-6100U found in several ultraportable laptops.
Many of these tests are subjective and depend on how a hardware manufacture configures and sets up the APUs in a laptop or tablet, but AMD does have its graphics tech to draw on, such as the GCN architecture, which could give it the edge over Intel’s chips when it comes to pushing pixels.
The APUs will be aimed primarily at slim laptops that need low-power consumption chips, much like Intel’s Skylake line.
Bristol Ridge is currently available to end users only in the form of HP’s latest Envy laptop. But now that AMD has debuted the full range of the seventh-generation APUs we can expect to see them in other ultraportable machines before too long.

Is nVidia Taking Qualcomm To Court?
Nvidia has dragged Qualcomm into court for allegedly crushing a $352 million chipset deal.
Nvidia claims it was forced to wind down its cellular mobile broadband chipset business, including its Icera unit just four years after buying it, because of Qualcomm’s anti-trust antics.
Qualcomm’s alleged tactics led to “unexplained delays in customer orders, reductions in demand volumes and contracts never being entered into, even after a customer or mobile network cooperating with a prospective customer has agreed or expressed a strong intention to purchase” Nvidia’s chipsets, the company moaned.
The claim for cash comes as European Union regulators step up antitrust investigations into Qualcomm sales tactics that officials said thwarted other designers of mobile-phone chip technology. This could result in fines or an EU order forcing a company to change its behaviour.
The EU thinks Qualcomm may have charged below-cost fees for chips used in mobile Internet modems known as dongles from 2009 to 2011 to thwart smaller competitor Icera. Regulators are separately probing what they say are exclusivity payments Qualcomm paid to a phone and tablet manufacturer for using its designs.
Qualcomm is “confident” it would prevail in both the EU investigation and the lawsuit.
Nvidia is seeking a declaration from the judge that Qualcomm’s conduct was an abuse of a dominant position, compensation, and an account of the profits it says Qualcomm gained from unlawful conduct, according to the court filings.

AMD’s Vegas GPU Details Spotted
Details of AMD’s Vega GPU were leaked and then taken down from AMD R&D Manager’s LinkedIn profile page over Easter.
Hexus spotted Yu Zheng, an R&D Manager at AMD Shanghai had listed the work on Project Greenland as a work experience highlight on his LinkedIn profile page. Greenland is described as “A leading chip of the first graphics IP v9.0 generation, it has full capacity of 4096 shader processor along with whole new SOC v15 architecture.”
The Graphics IP v9.0 designation is thought to signify a Vega GPU in the making. Zheng mentions this is an SOC, but then Hawaii and Fiji chips were described the same. Fiji is part of the graphics IP v8.0 family, as will be Polaris.
Vega following after Polaris, and designated as a ‘HMB2′ GPU by AMD, it looks like Vega based graphics cards will be the successors to the HBM equipped Fiji range such as the Radeon Fury and Nano. Fiju can manage 4096 stream processors, but with an upgrade to HBM2, 14nm process and other optimisation it is estimated that a Greenland/Vega GPU based graphics cards will offer 20 to 30 per cent better performance.
So with Greenland/Vega sporting HBM2 memory Hexus thinks that Polaris packing graphics cards will therefore feature GDDR5/X memory.

Is AMD’s FreeSync Coming In 2015?
Last week in San Francisco we spent some time with Richard Huddy, AMD’s Chief gaming scientist to get a glimpse what is going on in the world of AMD graphics. Of course we touched on Mantle, AMD’s future in graphics and FreeSync, the company’s alternative to Nvidia G-Sync.
Now a week later AMD is ready to announce that MStar, Novatek and Realtek scaler manufactures are getting ready with DisplayPort Adaptive-Sync and AMD’s Project FreeSync. They should be done by end of the year with monitors shipping in Q1 2015.
FreeSync will prevent frame tearing as the graphic card often pushes more (or fewer) frames than the monitor can draw and this lack of synchronisation creates quite annoying frame tears.
FreeSync will allow Radeon gamers to synchronize display refresh rates and GPU frame rates to enable tearing and stutter-free gaming along with low input latency. We still do not have the specs or names of the new monitors, but we can confirm that they will use robust DisplayPort receivers from MStar, Novatek and Realtek in 144Hz panels with QHD 2560×1440 and UHD 3840×2160 panels up to 60 Hz.
It took Nvidia quite some time to get G-Sync monitors off the ground and we expect to see the first 4K G-Sync monitors shipping shortly, while QHD 2560×1440 ones have been available for a few months. Since these are gaming monitors with a 144Hz refresh rate they don’t come cheap, but they are nice to look at and should accompany a high end graphic card such as Geforce GTX 980 or a few of them.
Radeon lovers will get FreeSync, but monitors will take a bit more time since AMD promises Project FreeSync-ready monitors through a media review program in 1Q 15 and doesn’t actually tells us much about retail / etail availability.
FreeSync Only For New AMD Chips
AMD has explained that its new FreeSync technology will only work in new silicon.
FreeSync is AMD’s initiative to enable variable-refresh display technology for smoother in-game animation and was supposed to give Nvidia’s G-Sync technology a good kicking.
G-Sync has already resulted in some top production gaming monitors like the Asus ROG Swift PG278Q.
However AMD said that the only the newest GPU silicon from AMD will support FreeSync displays. Specifically, the Hawaii GPU that drives the Radeon R9 290 and 290X will be compatible with FreeSync monitors, as will the Tonga GPU in the Radeon R9 285.
The Bonaire chip that powers the Radeon R7 260X and HD 7790 cards could support FreeSync, but that is not certain yet.
Now that would be OK if the current Radeon lineup is populated by a mix of newer and older GPU technology. What AMD is saying is that there are some brand-new graphics cards selling today that will not support FreeSync monitors when they arrive.
The list of products that won’t work with FreeSync includes anything based on the older revision of the GCN architecture used in chips like Tahiti and Pitcairn.
So if you have splashed out on the the Radeon R9 280, 280X, 270, and 270X hoping that it will be FreeSync-capable you will be out of luck. Nor will any older Radeons in the HD 7000 and 8000 series.
Nvidia’s G-Sync works with GeForce graphics cards based on the Kepler architecture, which include a broad swath of current and past products dating back to the GeForce GTX 600 series.
