Around 1980 was…

Dawn of Interactive Graphics Devices

Generating Video Signal Itself Was a Challenge for both computer and consumer devices

Very different price point

Around 2010 was…Desktop PC no longer relevant

• Continues to grow performance but…

• Evolving into dinosaur territory

Rise of mobile devices

• iPhone only launched in 2007 !

• Industry focus shifted

• Absorbing technology from PC

• Integrated into small form factor / low power

2013

• iPhone 5S / iPad Air

• Champion devices

• Snapdragon 800

• Powering the competing devices

2013 was…• Mobile GPU migrated to new architecture

• PowerVR SGX to R6xxx

• Adreno 2xx to 3xx

• Tegra3 to 4

• Mali T4xx to T6xx

• Catching upto DX10/11 level features

2014

• Feature mostly caught up to desktop

• Higher performance per Watt

• Pressure to lower price point

Summary• 1980: Barely driving video output. More bandwidth!

• 1990:

• PC wants more bandwidth for office

• Consumer wanted multimedia

• 2000:

• PC start embracing 3D graphics & multimedia

• Consumer push for bandwidth but still on SD

• 2005: Converge to PC technology

• 2010: Mobile devices emerge. Smaller form factor, lesser power

• 2013: Mobile devices catch up with PC features

• 2014: Mobile leads evolution

Also be Aware of…• Price point of the product

• Determines the market for the device

• Logic board pictures

• Big logic board with many parts == expensive

Conclusion• Focus for graphics hardware kept

shifting

• Bandwidth vs HW features

• To small and low power

!

Which way does it evolve to next?
