Show me non-niche software that needs more than a modern iGPU can provide. Your 3080ti can blast two screens of 4k video at 120fps HDR… and so can my iGPU.
Yeah but an xbox’s gpu can play games too. You don’t need a 3080ti to play any game on the market. Dedicated gpus are almost entirely a luxury upgrade with the power of today’s iGPU’s.
My 3080ti significantly out performs an Xbox. While you can game on a console you can game better on a PC with a dGPU. An iGPU will get the job done, but a dGPU today continues to outperform it and give you a better experience. I can play across 3 2k displays at 165Hz, or step up to native 4k, I can smooth framerates with raytracing on at a non upscaled resolution.
