GPUs, CPUs and SoC
- 1. GPUS ON SOC NVIDIA VS. AMD Prepared By: Omar Elshal 19-8014
- 2. OUTLINE • Introduction • CPU vs. GPU & APU • NVidia vs. AMD & INTEL • AMD’s Cross fire vs. NVidia's SLI • NVidia PhysX & CUDA • NVidia Tesla & Tegra • Market share • Who wins ? • References
- 3. 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.
- 4. CPU VS. GPU
- 5. APU ARCHITECTURE • Accelerated Processing Unit (APU) combines both CPU and GPU’s features. • Term first introduced by AMD.
- 6. 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.
- 7. 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.
- 8. 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.
- 9. 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.
- 10. 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.
- 11. NVIDIA SHIELD • Uses Tegra 4
- 12. 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.
- 13. 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.
- 14. 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

Notas do Editor
- Small cores used for executing data simultaneously, Polygon transformation(Floating point type) which are heavily used in Image Processing.
- From 32 cores to 2880 cores in NVidia Tesla K40. floating point operations per second
- In 2006, AMD acquired ATI CUDA (Compute Unified Device Arch.) CUDA™ is a parallel computing platform and programming model that enables dramatic increases in computing performance
- When GeForce Boost mode enabled both GPUs share the rendering load by rendering different frames.
- More realistic experience, walls can be torn down, glass can be shattered, trees bend in the wind, and water flows with body, snow accumulation \ AMD HD3D is 2 years late than NVidia 3D
- In 2012, Audi selected Tegra 3 for its in-vehicle infotainment systems and digital instruments display.
- Tegra K1 uses 64-bit processor with dual-core Project Denver;[56] the world's first 64-bit mobile chip running Android. Project Denver is the codename of a CPU/GPU-microarchitecture designed by Nvidia and based on the ARM instruction set.
- July 2013, NVidia shield firstly presented uses Tegra 4. AMD intends to release ARM System on Chips (SoC) that will begin sampling in early 2014
- However, as of February 2014, the specification has not been made public.
- AMD invests in CPUs and GPUs, they make custom APUs for the three major leading game consoles Xbox, PS, Wii NVidia make their own graphics stuff: CUDA, Tegra (SoC), Shield
