Which card do I need to plug into my computer?
I recently bought a very cheap gaming laptop for college work. It's the Lenovo Ideapad Gaming 3, model 15IHU6-D1. This one has an Intel i5 11320H processor, 16GB of RAM (which was upgraded from 8GB), a GTX 1650 graphics card, and a screen that supports 1080p at 60Hz. Now I'm asking myself... how do I know if the GPU is connected through the CPU's PCIe lanes or via the motherboard's PCH? The laptop shows up as having a PCIe x16 connection at PCIE v4.0, which also includes some channels at v3.0 that can be used by the CPU. But these same lanes could actually come from the PCH too. Since the i5 11320H supports PCIe 4.0 and has 20 total lanes (four for the motherboard itself and sixteen for other devices), it's a bit confusing about exactly which way my GPU is connected. I really want to learn more about this, but just so everyone understands what interface my laptop uses... what kind of connection does my GPU have?
Well, some TU117 chip versions actually support PCIe 4.0. But those chips are called MX450 and MX550, and they only have four or eight lanes. I guess if they had enough perfect TU117 chips, they could make a whole line of GTX 1650s with PCIe 4.0. But they probably would share the same four-lane or eight-lane setup, which might be true here. I wouldn't expect Nvidia to push these onto vendors anyway. Or maybe Lenovo would take a motherboard that only has four lanes and put different GPUs in it. Is your model available with an MX450 or MX550? If the signal quality wasn't high enough, they probably made the speed 3.0 just to avoid data errors. You can't expect them to skip cheap cutting corners on laptops like that. All the GTX 1650s in...
Click the ? next to Bus Interface and start the render test it idles low. thot the 1650 was pci-e 3.0 rather than 4.0 though. Your upgrade options are no Here's a demonstration teardown of your similar laptop on youtube The gpu is physically hardwired to the mobo in laptops not modular so if or perhaps when it ever develops a fault, it has to go back to the manufacturer or an electronics shop for reconditioning if that is even possible or they have spares available for it. This be not user serviceable besides memory, drives and the battery is modular so could be renewed by the user should it become necessary, while the CPU may also be hard soldered to the mobo rather than in a socket and not user serviceable. The gpu and cpu are under the heatsinks which you'd need to detach to determine what's socketed or not but probably aren't modular but hardwired so there's no real need to do that and you couldn't do anything even if you did remove the heatsink besides renew the thermal paste and then you'd only have to reassemble it correctly. So that 4.0 interface may be there more for the benefit of the manufacturer since they can use different varieties of gpu on the same mobo for different models in the range.
