Intel UHD Graphics (integrated in the Intel Core Ultra 7-265 processor). It doesn’t have dedicated VRAM like a discrete GPU.
A:AnswerThat optical port is not included. There is space for a full size GPU. but depending on the specific brand/make of the card, space will be limited. As the 3060 if different lengths, fan count, ETC
A:AnswerThere is a standard mini-dinn port on the front of the computer only which is not amplified. There is not a "sound card" but a chipset integrated into the motherboard for basic sound output. IMHO, it is suitable for providing sound for Zoom or other but there is no microphone port. Again, no sound ports on the back of the unit. This unit more corresponds to a Vostro than an XPS in older model terminology. The processor is fast.
A:AnswerDell computers are typically not intended for expansion. Whether you are looking at this unit or a Dell Tower Server, I strongly recommend you obtain all the internal parts you think you will need, such as power rails and data cables with your original purchase.
