Reduced runtime shader compilation overheadĪMD claims that Mantle can generate up to 9 times more draw calls per second than comparable APIs by reducing CPU overhead.

It is unknown when the Mantle specification and development materials will be released to the public, although AMD's director of software alliances and developer relations stated in an interview that Mantle may be made public in early 2014, or the year after.As of March 2014, the Mantle specification and development materials remain unavailable to the general public. The design goals of Mantle are to allow games and applications to utilize the CPU and GPU more efficiently, eliminate CPU bottlenecks by reducing API validation overhead and allowing more effective scaling on multiple cores, provide faster draw routines, and allow greater control over the graphics pipeline by eliminating certain aspects of hardware abstraction inherent to the current prevailing graphics APIs.ĪMD has stated that Mantle will be an open API. Currently the only implementation is for graphics processing units with AMD's Graphics Core Next architecture. Mantle is a graphics API specification developed by AMD as an alternative to Direct3D and OpenGL, primarily for use on the PC platform. With AMD technology inside all the most popular “next-generation” gaming platforms, including the PC, gamers across the entire industry will finally enjoy the best audio today’s technology can offer. Multi-channel specialization brings in-headset surround sound with accurate positional audio algorithms to all gamers not just the ones with the priciest headgear.īy leveraging AMD TrueAudio technology, game developers now have the ability to recreate acoustic environments with incredible fidelity, and to bring them to every gamer. The types of real-world acoustic phenomena that can be faithfully reproduced are massively greater. True to life echoes and convolution reverb are finally available on all platforms, meaning programmers can now build these effects into their games rather than relying on basic reverbs. AMD TrueAudio technology multiplies the number of sounds a game can generate at once, giving developers the capacity to create much more lifelike soundscapes. More voice channels and audio objects mean game developers no longer have the unenviable task of determining which sounds are expendable. They now have the flexibility to create complex effects and acoustic environments.

Game developers aren’t stuck with inflexible canned effects anymore. Programmable sound effects bring to audio the same kind of flexibility that programmable shaders brought to graphics. That doesn’t just enable new and exciting audio features in games it also saves CPU cycles that can be used for other tasks. That’s a hefty dose of processing power committed just to generating immersive soundscapes. Here are some of the features that make that possible:Ī dedicated digital signal processor (DSP) is built in to the AMD GPU core. How AMD TrueAudio removes constraints on sound developersĪMD TrueAudio technology is all about giving sound engineers the freedom to follow their imaginations and the power to make their games sound as convincing as they look. No Videos can be found at this stage that does not ruin the effect of FreeSync AMD’s theory as to why Nvidia built an expensive hardware solution for this problem is that Nvidia wasn’t capable of supporting G-Sync in any other fashion. AMD also told Tech Report that it believes triple buffering can offer a solution to many of the same problems G-Sync addresses. AMD has stated that the reason the feature didn’t catch on was a lack of demand - but if gamers want to see G-Sync-like technology, AMD believes it can offer an equivalent. AMD engineers demoed their own implementation, dubbed “FreeSync,” on a laptop at the showĭynamic refresh rates would theoretically work like G-Sync by specifying how long the display remained blank on a frame-by-frame basis, providing for smoother total movement.

Some panel makers offer support for this option, though the implementation isn’t standardized. Multiple generations of AMD video cards have the ability to alter refresh rates on the fly, with the goal of saving power on mobile displays. We believe FreeSync is to combat & show AMD trick up its sleeve vs Nvidia G-sync TechnologyĪccording to the company’s senior engineers, they can replicate much of the advantages of Nvidia’s G-Sync tech through the use of what are called dynamic refresh rates.
