8GB of VRAM could be all you can find in laptop GPUs soon — but is it enough? I tested the MSI Katana 15 HX to find out

Has 8GB got enough life left in it?

We're currently stuck in a PC market where RAM acquisition is the main concern, as prices skyrocket due to the ongoing AI boom, with consumers left to pay up or wait patiently for price drops, especially for the best gaming laptops.

You might be wondering why that matters in regard to the MSI Katana 15 HX B14W gaming laptop. Powered by the Nvidia RTX 5070 (laptop GPU), the Katana 15 HX B14W is also limited to 8GB of VRAM.

Now that last mention might throw most consumers off of purchasing, as 8GB of VRAM isn't desirable for game performance, considering the high system requirements from newer titles. Games are gradually becoming VRAM hungry, and with only 8GB of VRAM, users have to be reasonable with graphics settings and resolutions, especially when using Frame Generation, which utilizes more VRAM.

Also, in case you're unaware of how I've felt about 8GB VRAM GPUs in both laptops and gaming PCs, I'll say this: I don't like them and have always pushed for 12GB to be the new minimum.

However, the MSI Katana 15 HX B14W proved me wrong in some areas, with results ending up different from what I was expecting, even in a few of the toughest scenarios that would usually spell a complete collapse on low VRAM GPUs. However, it's not all great, and there's a reason why 8GB of VRAM is frowned upon.

Maybe 8GB of VRAM isn't so bad after all?

It's not unreasonable to expect an 8GB GPU to provide good performance in games that don't have demanding system requirements, but the real question is, how well can it perform in some of the most demanding games of the last decade?

That's exactly what I put to the test; in Cyberpunk 2077 at 1440p using DLSS balanced on the ultra graphics preset, I managed an average of 90fps, which is very impressive considering how great Nvidia's DLSS 4 is in image quality, thanks to the transformer model replacing the former CNN (Convolutional Neural Network) model.

A step up to the ultra ray tracing graphics preset gave me an average of 54fps, and it's no secret that Cyberpunk 2077's ray tracing is no easy hurdle for any graphics cards to jump over, so that's another positive for the Katana 15 HX's RTX 5070.
