Media

The AMD Radeon™ R9 295X2 graphics card is the world’s fastest, period.  A mammoth eight gigabytes of memory and over 11.5 teraflops of computing power help this card do what it was built to do: be the undisputed graphics champion for a generation.

Engineered for ultimate performance:

When you’re holding all the cards, it makes sense to double down. We took two of our most advanced GPUs and put them together in one cohesive unit.

Games enabled with Mantle technology speak the language of Graphics Core Next to unlock revolutionary performance and image quality.

Run ultra settings in 4K with impunity. Or get two million pixels more than 4K by combining five HD screens in an AMD Eyefinity technology setup. Either way, the AMD Radeon R9 295X2 barely breaks a sweat.

AMD TrueAudio technology puts the magic of surround sound into every headset and gives sound engineers the freedom to innovate. This is what the future of PC gaming sounds like.

Why we Developed Mantle

From a game developer’s point of view, creating games for the PC has never been especially efficient. With so many combinations of hardware possible in a PC, it’s not practical to create specialized programming for every possible configuration. What they do instead is write simplified code that gets translated on-the-fly into something the computer can work with.
AMD Mantle technology

Just as when two people communicate through a translator, this works, but it isn’t efficient. And it’s the CPU that has to do all this extra work, translating and queuing data for the graphics card to process. PCs are meant to be the ultimate gaming platform — they have the power — but all this translation slows things down, and game developers approached AMD asking for something better.

What Mantle does Cutaway showing the inner layers of the earth

Mantle is the harmony of three essential ingredients:

  1. A driver within the AMD Catalyst™ software suite that lets applications speak directly to the Graphics Core Next architecture;
  2. A GPU or APU enabled with the Graphics Core Next architecture;
  3. An application or game written to take advantage of Mantle.

Mantle reduces the CPU’s workload by giving developers a way to talk to the GPU directly with much less translation. With less work for the CPU to do, programmers can squeeze much more performance from a system, delivering the greatest benefits in gaming systems where the CPU can be the bottleneck.

GCN Architecture

Primed to enable astonishing performance and breathtaking image quality

Available on select AMD Radeon™ R7 series, R9 series and HD 7000 series graphics cards, the visionary Graphics Core Next (GCN) Architecture is a radically new approach to the design of a consumer GPU, making it a top choice for gamers who expect the best.

Designed to push not only the boundaries of DirectX® 11 gaming, the GCN Architecture is also AMD’s first design specifically engineered for general computing.  Representing the cutting edge of AMD’s graphics expertise, GCN GPUs are more than capable of handling workloads-and programming languages-traditionally exclusive to the main processor. Coupled with the dramatic rise of GPU-aware programming languages like C++ AMP and OpenCL™, the GCN Architecture is the right architecture at the right time.

Performance

In simple terms, increasing the number of transistors in a GPU has a big impact on the potential performance of a graphics card, but transistors alone are not enough. It takes a truly great design, like the GCN Architecture, to effectively use that potential and turn it into real-world performance.

Image Quality

Performance is not enough for today’s demanding gamers. Image quality, or the clarity and accuracy of textures and effects, is equally important. The GCN Architecture is equipped with three key technologies that dramatically raise the bar in this regard.

Partially Resident Textures (PRT)

Even in the latest titles, gamers may have noticed that games often reuse or repeat textures, particularly on the ground or in background scenery such as mountains or trees. This is because increasing the physical size or number of textures in a game can have a negative impact on the performance of a GPU. PRT is a radical technology that hopes to break this cycle.

PRT can utilize absolutely enormous texture files, up to 32 terabytes large, with minimal performance impact. PRT accomplishes this by streaming small bits of these massive textures into the GPU as needed, giving compatible games a virtually endless supply of unique texture data it can apply to the game world. The GCN Architecture in AMD Radeon™ products is the first GPU design to feature a hardware implementation of this technology.

Partially Resident Textures (PRT) enable future games to utilize ultra-high resolution textures with the same performance as today’s small and often repetitive textures.

Improved Anisotropic Filtering (AF)

Available on every modern GPU, anisotropic filtering is a technique that assists the GPU in making sure textures in your favorite games remain razor sharp, even at a distance. Most games now offer the ability to enable this feature, and the AMD Catalyst™ driver suite has long provided players with the option to force enable anisotropic filtering for all of their games.

Where every GPU design differs, however, is in the way the anisotropic filtering is actually executed. The GCN Architecture has been specifically optimized to produce superior results when AF is enabled.

Improved anisotropic filtering enables gamers to get sharper, better textures when this technology is enabled.

Efficiency

Finally, it’s important that great performance and great image quality don’t come at the expense of a high power bill. Products with the GCN Architecture feature reduced power consumption in the “idle state,” better known as the time when you’re doing desktop work. But there’s more, too.

AMD ZeroCore Power Technology

AMD ZeroCore Power technology leverages AMD’s leadership in notebook power efficiency to grant our desktop GPUs the ability to power down when your monitor is off, also known as the “long idle state.”

This is great for those times when you’ve stepped away from your PC to take a call, watch TV or pop down to the store. Furthermore, AMD ZeroCore Power technology allows additional GPUs in an AMD CrossFire™ technology configuration to shut off when they’re not in use-even the fan stops spinning.

An AMD-exclusive technology, AMD ZeroCore Power ensures that unused or idle GPUs are as efficient as possible.

Even the most hard-core gamer with an AMD CrossFire™ multi-GPU configuration benefits from AMD ZeroCore Power technology. Unused or idle GPUs are shut down until needed to conserve power.

AMD TrueAudio

Your games now sound as good as they look

The expectations of gamers have never been higher. Graphics quality and processing speed have advanced rapidly, and the games of today are light years ahead of those from just a few years ago. But advancements in game audio have been more sporadic and less widely adopted.Sound is a critically important part of the immersive experience for gamers and sound engineers are eager to advance their art, but they haven’t enjoyed the same kind of attention that continually drives graphics improvements.Until now.

AMD TrueAudio technologyHow AMD TrueAudio removes constraints on sound developers

AMD 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. Here are some of the features that make that possible:

  • A dedicated digital signal processor (DSP) is built in to the AMD GPU core. That’s a hefty dose of processing power committed just to generating immersive soundscapes. That doesn’t just enable new and exciting audio features in games; it also saves CPU cycles that can be used for other tasks.
  • Programmable sound effects bring to audio the same kind of flexibility that programmable shaders brought to graphics. Game developers aren’t stuck with inflexible canned effects anymore. They now have the flexibility to create complex effects and acoustic environments.
  • More voice channels and audio objects mean game developers no longer have the unenviable task of determining which sounds are expendable. AMD TrueAudio technology multiplies the number of sounds a game can generate at once, giving developers the capacity to create much more lifelike soundscapes.
  • 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. The types of real-world acoustic phenomena that can be faithfully reproduced are massively greater.
  • Multi-channel spacialization brings in-headset surround sound with accurate positional audio algorithms to all gamers; not just the ones with the priciest headgear.
