At the end of last year, we forecast that the performance gaps between the mobile GeForce RTX 30 and the desktop GeForce RTX 30 compared to the previous RTX 20 generation would widen after the first RTX 30 laptops hit the market Unfortunately, our internal tests on a handful of GeForce RTX laptops confirmed our prediction.By switching from a mobile RTX 3080 to a desktop RTX 3080, users can see a 50 to 60 percent increase in raw graphics performance compared to just 10 to 15 Percent between the mobile RTX 2080 and the desktop RTX 2080 Similar results are found for the RTX 2070 series, but this page focuses on the RTX 3080 series
The culprit for this generation’s big performance difference is not a big surprise. Desktop gamers have probably noticed by now that their GeForce RTX 3080 graphics cards perform around 40 percent significantly better than their older RTX 2080 cards (320 W vs. 225 W) As a result, RTX 3080 cards tend to be thicker and cooler than the older RTX 2080 cards to compensate for this
On laptops, the TGP ratings have hit a wall.The mobile RTX 2080 is rated for a maximum of 150W, as is the latest mobile RTX 3080, which means the new mobile Ampere series will have to run under similar power limitations as the older one mobile Turing series
Increasing the power cap for mobile amps by significant margins was likely impossible during development, as these chips have to fit into the same laptop models and thickness grades that were designed for mobile PC makers have their thin and light laptops specially designed for them tuned to certain power levels, and increasing the power cap by about 40 percent would inevitably mean thickening their respective case designs.We certainly doubt that OEMs want to take this into account now that consumers are turning to successful, thin and sleek Max-Q game models like the MSI GS66, the Razer Blade, the Gigabyte Aero or the Asus Zephyrus
That’s not to say the mobile RTX 30 series doesn’t have any improvements over the mobile RTX 20, but the gains are relatively small, especially if you’re playing at lower resolutions like 1080p or 1440p, and it will be interesting to see where Nvidia is going and where PC makers are going from here as the limits of cooling technology are now an even bigger obstacle to improving mobile graphics performance than ever before
