    Cerebras teases 850k core 2nd-generation wafer scale engine

    The full wafer chip packs in 2.6 trillion transistors thanks to a move to TSMC 7nm.

    This is crazy because it's a testament to TSMCs 7nm process that its defect rate is so low that Wafer-Scale engines can be build off its process. Amazing

    Kind of puts to bed the claim you hear from the pro-Nvidia crowd about yields and die sizes being a justifiable reason to charge consumers £1.2k for a GPU. Sure its not easy but WSE is the cutting edge and limits not a 600mm2 die

    ROFLMAO. $1200 vs. 2.5m each unit? No, sort of says EXACTLY what NV says about die sizes. A huge die sells in a machine for 2.5M dollars.

    If you divide 46000 mm^2 by 800 (roughly TSMC reticle) you get about 58. 58x1200=69,600, so charging around 2.5M shows as you grow that chip size, you massively charge more money. The math just doesn't lie here, it is what it is. IF this was NV chopping it up into 58 800mm^2 dies, they'd charge around 70K for them, and that is the ENTIRE CARD, not just 58 chips. So is NV screwing you at 70k for the size of the entire wafer basically, or is this company at 2.5M for them all combined into ONE chip/wafer (whatever)? Probably NEITHER are screwing you, it is what is required to make profit. I doubt they made money here. It sounds like rev1 sold 2 units for 5mil. With all the design etc into making this box work, probably a mass loss to prove it could be done, but gen2 likely makes money after lessons learned, and people knowing it works. More sales will come, volume will help, die shrink, etc. From 16nm to 7nm means massive perf gains, power drops, etc, so again, I think they will make money this round if they didn't before.

    That said, NV isn't screwing anyone or products would be left on shelf. If your price is too high, products don't move. So YOU are the problem here, not them. Improve your income so a $1000 gpu means nothing to you. I can buy one every year if desired easily. I choose not too (not willing to pay rich tax for 10% perf, I buy a few down), but because it just isn't worth it to me. I'm not rich enough to not care at all, and have better things to do with my money until a die shrink etc gets what I want at a price I'll pay. I could improve my income too, until I don't care at all (trying..LOL). That is what you should be doing your whole life. Add value to YOU, by constantly upgrading your skills, or make money ON your money (the best way). Then you do nothing but monitor it, and research to make more on it. Stocks! They've paid for my parts for decades. I don't pay for PC parts out of checks from work, I buy a part when stocks etc make it free.

    You are trying to make the world fit in your income, when you should be trying to get your income to fit the world you want to provide for yourself. IE, if a you want a lambo, don't expect to get it working at walmart. You will have to improve your life enough to afford the car, the dang insurance, repairs, etc. You can wait forever for something to come to your budget, or grow your income so you can finally afford it. The choice is yours, or just keep complaining about prices I guess..

    Wow, just wow.

    I have to wonder what the actual defect rate is though, it can't be cheap to produce an entire WSE, unless they designed it to include potential redundancies due to manufacturing defects.

    It'd be unworkable if they didn't plan to fuse off defective areas. Even the new xbox isn't fully enabled, although I concede that there's no good use for dies which fall slightly below the standard making it harder for them to make a fully enabled die - with wafer scale you can just flog off the 85% wafers for a bit less than the 90% wafers
