The MSI slides say the 9750H is 28 percent faster than the 8750H, and that the GeForce GTX 1650 scores 11294 points in 3DMark, versus, 7979 for the GeForce GTX 1050 and 9114 for the GTX 1050 Ti.
According to Google Translate, the GTX 1650 will replace the 1050 (no surprises there) but will be significantly faster. MSI reveals some 3DMark figures that claim the GTX 1650 scores 11294 points against the 1050's 7979 and the 1050Ti's 9114. MSI also says the GTX 1650 will provide 60 or more frames per second in games like Assassin's Creed, Fortnite, PUBG, and GTA V. The GTX 1650 will have 4 GB of VRAM, just like the mobile 1050, and its clock speed is 1395 MHz (MSI's promotional material doesn't specify if this is a sustained clock speed, base clock speed, or turbo clock speed).More at Tom's Hardware.
