This article is a quick breakdown of the differences between Intel® Graphics Performance Analyzers (Intel® GPA) and Intel® VTune™ Amplifier. We will cover what types of problems each tool can solve and the type of developers that will get the biggest benefit out of each tool.
Intel® VTune™ Amplifier
Is recommended for programmers involved with game play and/or game engine development. Developers can take advantage of detailed source code profiling data to optimize compute intensive tasks such as physics, AI. Intel® VTune™ Amplifier provides insight to tune both single threaded and multithreaded performance.
Game developers can use the tool to:
Intel® Graphics Performance Analyzers
Intel® GPA is recommended for artists, designers, and game engine programmers. Gameplay programmers can use it in conjunction with Intel® VTune™ Amplifier as the tools provide different functionality. Intel® GPA a free set of powerful graphics analysis and optimization tools to help developers improve performance of games and other graphics-intensive applications.
Game developers can use Intel® GPA to:
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
