hex dies
nice
Before you decide to write yet another dumb comment about how there are other costs than the bill of materials, consider the fact that 100% of the intended audience of this video is aware of that fact. You are not adding anything to the discussion. Go away.
Paraphrasing Intel: every die wants to live
nice
Question – probably stupid:
Context:
The IOD is less populate and can use less "dense" components, meaning a transistor with a "defect" might be still working because it's BCE are broad enough to just not be influence enough to be actually defective.
Hence the question: How much of an influence has structure size on the yield rate? if true, Q#2: Could the IOD therefore have a better than calculated yield rate?
1'2 million per stepper did you added that cost?
A 7950X CPU to go with their 7900XT GPU. They should hire someone to name their products.
research is not cheap
You can put easy more 80 dollars in your math
You forgot the chip testing. Nobody will glue an untested die in the package
The package where the chiplets are placed can cost more than the silicon. Is a piece of art
Yield of state of art process nodes are not good. Lots of cores are lost until the foundry master the fabrication.
we need a video like this based around GPUs from now on…
The packaging of the CPU, design, manufacturing of the box is ignored here! Most people do not have access to O.E.M. 7950X that are purchased in 1,000 quantities!😊
Go print in the die, until you die hahaha, R&D cost will clap and disregarded hahaha
🐮Bull shit 🐮
Tell me you don't know jack about business without telling me you don't know business.
"Direct cost". Who gonna account for the indirect costs like salaries, R&D, design, etc?
those bilions worth lasers equipament… would be nice put their price inside too
Why is everyone talking about TSMC raising its prices by 20%? That's only $ 10 – $15 if you think about it. Should have minimal impact on overall retail prices of cpu, gpu, etc…
Great to do the same calculation for the new gen GPUs, especially the new Navi 31 chiplet design given it uses the same technologies. An interesting comparison would be how much it would cost if it wasn't a chiplet architecture in a very rough estimate for both cases.
Yeah it takes 3 months to make a single chip. That 3 months of overhead not to mention the R&D it took to develop new fabricators. A single machine costs 150 million and they probably have to replace them as soon as possible to keep developing more precise machining. The level of precision on these machines is bonkers. They also have to use a lot of different high purity gases for the lithography so that's another material cost and the building has to have such clean and pure air inside of it because a spec of dust could ruin a chip so I would be willing to be there's a lot of crazy air ventilation and purification going on.
