So the AMD GPU '14 stream came and went in a flash last night. During the event AMD unveiled their new range of cards consisting of the Radeon R9 290X, R9 290, R9 280X, R9 270X, R7 260X and R7 250 as well as introducing the Mantle API and AMD TrueAudio technology.
The cards speak for themselves, the R9 290X will be AMD's flagship card, and whilst AMD didn't announce the full specifications they did say that the card should push 5 TFLOPs of GPU performance. Which to put into perspective the Nvidia GTX Titan is able to push 4.5TFLOPs of GPU power. The R9 290X will come equipped with 4GB of memory which will have a total memory bandwidth of over 300GB/sec.
Mantle is designed as a directly interfacing API which will bypass the use of Direct X 11 on AMD Graphics Core Next GPU's. This will allow games to talk to the graphics card directly, in practice games using this technology will receive a welcome performance boost. Mantle also offers benefits to developers as AMD are the force behind the next-gen consoles, Mantle is simalar to the technology used, meaning porting between consoles and PC should be easier (I hope you heard that Rockstar).
"With Mantle, games like DICE’s “Battlefield 4” will be empowered with the ability to speak the native language of the Graphics Core Next architecture, presenting a deeper level of hardware optimization no other graphics card manufacturer can match." the company said on Wednesday "Mantle also assists game developers in bringing games to life on multiple platforms by leveraging the commonalities between GCN-powered PCs and consoles for a simple game development process."
TrueAudio Technology, appears to be simlalar to existing technologies that allow for virtual surround sound, but the AMD technology takes this sever steps further as it will allow for more channels of audio creating a more immersive audio experience
AMD TrueAudio technology marks a new frontier in realism for PC gamers. AMD TrueAudio technology empowers game developers with a programmable audio pipeline on the GPU, inviting them to put their unique artistic fingerprint on in-game audio in the same way that the programmable graphics pipeline brought unfettered artistic vision to PC graphics. Enabled games can feature more realistic environmental dynamics, a richer tapestry of sound effects, breathtaking directional audio and more.
AMD TrueAudio technology enhances audio realism by simulating the human brain’s perception of real-world sound, working in concert with the user’s existing audio hardware to recreate a lifelike experience in upcoming games like “THIEF™” by Square Enix or “Lichdom” by Xaviant Games.
A brief video of the technology can be seen below, it works best with headphones.
