Are AMD's chips really much cheaper than Intel's chips?
Per core? Hell yeah!
This got me curious. I would expect this to be true but how much does the cheapest CPU with certain amount of cores from either manufacturer actually cost?
AMD lineup:
8-core $299 (Ryzen 7 2700)
6-core $199 (Ryzen 5 2600)
4-core $100 (Ryzen 5 2200G)
2-core $55 (Athlon 200GE)
Note that Ryzen 7 3700X will be 329, raising the 8-core bar slightly.
Intel lineup:
8-core $323 (Core i7 9700)
6-core $182 (Core i5 9400)
4-core $122 (Core i3 9100)
2-core $42 (Celeron G4900)
Less of a difference than I expected.
Well, we know that Intel makes their chips as a monolithic die meaning all of the stuff that makes that processor is on that one die. Considering that the 7700K launched at a price of $305 USD, then the 8700K with two more cores and the launch price is $359 USD. OK, $50 more for two more cores ain't bad. But here we have the 9900K with an insane MSRP of $488 with many selling for more than that. Holy crap!
Why did adding just two more cores on top of the already six cores of the 8700K shoot the price up so badly? The only thought that comes to mind is that too many 9900K chips are coming off the line with defects in them. So if you want one, be prepared to pay dearly for it.
You are basing this squarely on price. That is a bad indicator. Pricing is much more marketing than technical thing.
i7 7700K never really sold for $305. Its retail price was pretty much $350-360, even more so with i7 6700K still being sold and occupying the slot at $300-ish. i7 8700K effectively formalized that price.
i9 9900K is the top processor of the class you can get which inevitably comes with a price premium. Ryzen 9 3950X is bound to take that spot now with $250 (50%) higher price over Ryzen 9 3900X for 4 extra cores.
