$NVDA:
1) GPU market share & tech leader.
2) Rapidly rolling out new platforms with large performance gains every year.
3) 31x forward EPS; 0.4x forward 2-yr PEG

$AMD:
1) Not the GPU market share or tech leader.
2) Trying to catch up to a competitor that continues to sprint faster than they can.
3) 44x forward EPS; 1.1x forward 2-yr PEG

If you've decided you want exposure here... why would you pick $AMD over $NVDA? Why pick the 2nd best at a higher growth multiple?
