How does a GPU/CPU communicate with a standard display output? (HDMI/DVI/etc)

I am interested in how the cpu/gpu presents (to whatever equipment that it does) video data after it has been processed. I have been told that the video is processed by the CPU/GPU and then sent to an integrated circuit by high speed serial that…

Why does GPU consume so much power?

I am trying to understand why GPUs consume so much power. For example, the max power consumption of the P100 GPU is 250W. As I understand power is measures in watts as current x voltage. Given a fixed power source (i.e. voltage), I would assume that…

Why are there separated power circuits for CPU, GPU, and RAM on a motherboard?

Even though there is a power supply unit in a computer case, why are there separated power circuits for CPU, GPU, and RAM on the motherboard? I mean, why can not the CPU, RAM and GPU just take their energy from the power supply unit?

Where to start when considering making a GPU?

I saw this video the other day and it got me thinking about how to go about and design something like the GPU. Where would you begin? I'm more just interested in reading about how they work and not making one out of TTL(yet anyway). I know this…

Can I use a 250 nF instead of a 200 nF SMD ceramic capacitor?

Im trying to fix a broken GPU that has a missing 200 nF SMD ceramic capacitor. I found a similar one on a motherboard that has a capacitance of 250 nF. Is it possible to transfer it to fix the GPU? At first if thought the capacitors were 220 nF…

How is quality/damage control done in large circuits?

There is apparently more than 28 billion transistors in the recently released Nvidia GeForce RTX 3080. First, when you manufacture such a circuit there must be a decent chance of botching some of these. How do the plants make sure that they all…

GPU reflow soldering profile

I've had my ENGTX480/2DI/1536MD5 GPU for 3 and half years now. Over the past 2 months it started causing trouble. At first, it started seldom displaying big zones with weird color, but simply turning my TV off and on again and it got back ok. Then…

Low voltage GPU decoupling capacitor longevity

Recently noticed my GPU card (Nvidia 1060) made more coil noise (electrical noise, noise level proportional to frame rate) than usual. I discovered that directly behind the GPU chip one of 2 big 470uF, 2 volt capacitors had broken off. I just…
