WCCF Tech has more details and even received benchmark results from its source, but unfortunately the scores are from the very old 3DMark11 test:
All the benchmarks you see above were conducted in a mobility environment and using a Ryzen 7 processor. The GTX 1050 Ti (the last-gen mainstream mobility king) scores a cool 9000 points in 3DMark 11. The GTX 1650, which also rocks DDR5, manages 10000 points. The upcoming Radeon RX 5300M mobility GPU from AMD scores 11000 points – making it faster than the GTX 1650 from NVIDIA. The GTX 1660 Ti is the first card to introduce GDDR6 in this ranking and in a Max-Q format achieves 12000 points. The upcoming Radeon RX 5500M mobility GPU scores 13000 points. NVIDIA’s GTX 1660 Ti in a non-MaxQ format still manages to retain the performance crown with 14000 points.Both parts are expected later this year.
