INTRODUCTION
• Graphics Processing Unit (GPU) is a specialized processor that offloads 3D graphics rendering from the microprocessor.
• Used in ES, mobile phones, laptops, tablets and game consoles..etc.
• GPU cores are smaller and much more than CPU cores.
• CPU have weakness in Linear data execution used for
rendering pixels.
APU ARCHITECTURE
• Accelerated Processing Unit (APU) combines both CPU and GPU’s features.
• Term first introduced by AMD.
NVIDIA VS. AMD & INTEL
• Dedicated GPUs are much more powerful than integrated GPUs.
• Most if not all Intel GPUs are integrated ones.
• NVidia CUDA cores vs. AMD stream processors.
• NVidia's CUDA for parallel programming
• AMD powers Xbox one, PS 4 and Wii U by a custom-built APU.
AMD’S CROSS FIRE VS. NVIDIA'S SLI
• Both use the same concept of making use of more than 1 GPU to provide increased graphics performance.
• Hybrid SLI enables motherboard GPU to work with Dedicated GPU using GeForce Boost Mode.
• Each GPU render different frames allowing optimal performance.
• CrossFireX is not limited to using the same GPU model unlike SLI.
• HybridPower mode/OPTIMUS allows switching off dedicated GPU if not needed lowering system power, noise and heat.
NVIDIA ADVANCED PHYSX & 3D VISION
• NVIDIA® PhysX® is a powerful physics engine enabling real-physics in video games made exclusively for NVidia GPUs.
• PhysX is all about how objects move, interact and react.
• CPU does the PhysX for AMD but only NVidia GPUs allows using Advanced PhysX allowing a better visual experience.
• 3D Vision kit and glasses allows 3D gaming experience for supported games.
NVIDIA TESLA & NVIDIA TEGRA
• Tesla is used in some of the world’s fastest supercomputers nowadays.• 2008, Tegra is a System on Chip (SoC) series for smartphones, tablets and
mobile gaming consoles.• Tegra K1 in Q2 2014.
TEGRA K1• The Power Of An Xbox In A Mobile SoC, includes 192 GPU cores
• Support pc gaming technologies DirectX 11, OpenGL 4.4
• The first mobile processor to run Unreal Engine 4
• The only mobile GPU to support NVidia CUDA and other NVidia Technologies.
AMD’S MANTLE• AMD’s Mantle is a graphics API like DirectX and OpenGL but provides higher
performance.
• Utilize the CPU and GPU more efficiently.
• AMD claims to be an open API.
• Works only on AMD GPUs.
MARKET SHARE
• Intel owns nearly 49.4%, due to their integrated graphics solution being counted.
• Not counting those numbers, NVidia and AMD control nearly 100% as of 2008.
WHO WINS?
• For AMD and NVidia, success factors do not differ much.
• Every company whether Intel, AMD or NVidia leads in some particular field.
• They do not limit their innovation in one field.
• All companies started going SoC
