In the Asia region, a number of presentation slides have leaked, they originate from MSI and shows some numbers based on a laptop with the pending Core i7-9750H and GeForce GTX 1650.
The specs and number are derived from a new GL63 Laptop that MSI is about the present. If you look closer at the materials found, the proc is roughly 28% faster than the Core i7-8750H (current generation). If we zoom in at the GeForce GTX 1650, then that one would be would roughly 40% faster than the GTX 1050 and almost 25% faster than the GTX 1050 Ti. The screenshot shows a 1395 MHz frequency (likely base clock) and the dozens of times confirmed 4 GB GDDR graphics memory. The numbers originate from @momomo_us shared on Twitter.
