VLIW architecture is so bad that AMD and Nvidia couldn't make it work well with embarrassingly parallel graphics code. AMD first moved from VLIW-5 to VLIW-4 because they couldn't find enough data to reliably keep unit 5 busy. AMD then followed Nvidia into the world of SIMD/SIMT because it offered better real-world performance for the majority of applications. VLIW has been tried repeatedly only to be replaced with something that worked better.
