Description: Intel® Graphics Global Momentum Optimizing platform performance for Intel graphics Optimizing software performance for Intel graphics CyberLink*PowerDirector*software optimizations for Shared Virtual Memory (SVM) and OpenCL™ 2.0 Optimizing platform performance for Intel graphics Optimizing software performance for Intel graphics As reported by Mercury Research, “The attach rate for notebook discrete graphics has been falling in recent years, down to24% in the March 2014quarter compared to 36% in the September 2011 quarter” CyberLink*PowerDirector*software optimizations for Shared Virtual Memory (SVM) and OpenCL™ 2.0 Graphics Performance Design ConsiderationBest Memory Configuration •Dual Channel -Theoretical maximum Bandwidth = ((Transfer Rate*Number of Memory Channels*Channel Data Bits)/8)/1000 -Dual channel will be have 25.6 GB/S, twice single channel -Same memory combination can max. the dual channel performance •Multi-Rank Memory -Multi-rank DIMMs have higher bandwidth which allows them to have more pages open (due to double the resources available) -Since Graphics memory accesses are more scattered, it is expected to see more benefit from higher number of open DRAM pages (page miss/empty cases degrades DRAM bandwidth) Graphics Performance Design Consideration-Power Delivery Design Considerations •AC brick, battery and VR -Design should follow processor sustained and peak power/current requirements •Calibrated Imon–high accuracy per system design -Over reporting impacts performance -Under reporting impacts thermal behavior Designing to Scale from Intel® HD to Intel® Iris™ Graphics Solutions •Power delivery capability must meet Intel requirement for Iris / Intel® Iris™ Pro performance •Imonmust be calibrated accurately to avoid performance loss or thermal impact
