AMD Expects Trinity to Offer 20% - 30% Performance Increase.

AMD's Projections Show Tangible Performance Increases of Trinity

Earlier this year Advanced Micro Devices said that its forthcoming code-named Trinity accelerated processing unit would boost performance-per-watt by 50% compared to Llano. In the real-world applications, the company's new documents show that its next-gen APU will only be 20% faster in general-purpose tasks and 30% faster in graphics processing applications compared to existing chip.

According to a slide that resembles those from AMD's presentations published by DonanimHaber web-site, AMD projects Trinity's Piledriver x86 cores to offer up to 20% higher performance compared to Husky x86 cores inside Llano. In addition, the newly-architected DirectX 11 graphics core will provide up to 30% higher speed in graphics applications, such as video games. The 10% improvement represents AMD's projections "using digital media workload" and actual performance advantage over currently available Fusion A-series "Llano" vary depending on the applications and usage models. It is unclear whether AMD used an early silicon (which it has at hands) for its projections or makes its predictions based on theoretical data.

It is also unknown whether the projected performance increase will be conditioned by AMD Turbo Core 3.0 dynamic acceleration technology, new instructions support, higher clock-speeds or actual improvements of execution efficiency.

Since Trinity will be based on Bulldozer/Piledriver micro-architecture, AMD will have to clock the x86 cores at very high clock-speeds compared to existing offering to boost performance substantially since its latest micro-architecture in some cases is less efficient than the predecessor in terms of performance per core and per clock.

AMD’s second-generation code-named Trinity APU for mainstream personal computers (Comal for notebooks and Virgo for desktops) will be made using 32nm SOI HKMG process technology at Globalfoundries. The APU will feature up to four x86 cores powered by enhanced Bulldozer/Piledriver architecture, AMD Radeon HD 7000-series "Southern Islands" graphics core with DirectX 11-class graphics support, DDR3 memory controller and other improvements. The chips will be compatible with new FM2 infrastructure.

AMD claims that Trinity will offer up to 50% improvement in GFLOPS performance with the same power consumption as currently available A-series "Llano" APUs or similar GFLOPS horsepower with 50% reduction of power consumption.

AMD did not comment on the news-story.
