The latest generation of Intel Core CPUs have arrived accompanied by the new Z490 platform. Incredibly, there are over 50 Intel Z490 motherboards on the market, with prices ranging from $150 all the way up to $1,300. Here's what you should buy.

and how many times in your life have you upgraded a CPU without MOBO?If I was building a PC, I'd pick an AMD CPU and a respective motherboard anyways - a couple FPS more in a game is not worth switching a mobo every time I upgrade a CPU.

AMD and Intel have the same upgradability though. Both the x570 and the z490 will support 1 more cpu upgrade.If I was building a PC, I'd pick an AMD CPU and a respective motherboard anyways - a couple FPS more in a game is not worth switching a mobo every time I upgrade a CPU.

Nobody is going to buy an x570 with a 2000 series. Let's be realisticX570 supports 2000 and 3000 series CPUs right now. When Zen 2 launches that will also include 4000 series CPUs. That's 3 generations already. Intel at most will support 2.

In the old days, several.and how many times in your life have you upgraded a CPU without MOBO?
No. Worthwhile upgrade needs to be at least around 50% faster (calculated).
i7-8700K
Base clock 3.70 GHz
Turbo 4.70 GHz
i9-9900K
Base 3.60 GHz
Turbo 5.00 GHz
We have same architecture, slightly lower base clock, slightly higher turbo clock, bigger core-to-core latency etc so improvement is around 35% max. Also price is huge so that's not worthwhile upgrade.
When comparing AMD:
3950X
Max Boost: 4.70 GHz
Base: 3.50 GHz
2700X
Max Boost: 4.30 GHz
Base: 3.70 GHz
We have around 15% better IPC from architecture, slightly lower base clock, slightly higher boost clock, double amount of cores.
Improvement is somewhere around 110+%.
Also because AMD motherboards are miles better than Intel ones, upgrading from i7-8700K to i9-9900K makes very little sense, better to buy AMD CPU + motherboard.
Except he was speaking about i5 8600K upgrade. The upgrade from an 8600K, a quite popular CPU, to a 9900K makes sense.
A 10700K, certainly, but probably not a 10900K as the 1151 socket layout was never really designed for 10 cores - the 2066 layout was always required (as it was designed for up to 18).Good to have choice, but I still feel ridiculous that Intel forced us to change motherboard with a 10th gen that is not different from a slightly overclocked 9th gen.
The socket change was just a marketing move, and many good quality Z390 motherboards would have been ok for a 10700K or a 10900K.
I said 8600k. Or an 8400. Or even an 8100. How is a 9900k not a worthwhile upgrade over themNo. Worthwhile upgrade needs to be at least around 50% faster (calculated).

You hardly get a 50% increase from an 8600k to a 9900k? The fanboy is strong with this one.It hardly does.
8600K:
Base: 3.60 GHz
Turbo: 4.30 GHz
Max turbo is 16% higher, IPC is same, HT is enabled, core count is 33% up. We hardly get that 50% calculated improvement on outdated platform. Also as AMD example shows, that 50% is pretty low improvement as AMD usually (this time too) offers over 100% improvement.
So it makes some sense but very little.
A 10700K, certainly, but probably not a 10900K as the 1151 socket layout was never really designed for 10 cores - the 2066 layout was always required (as it was designed for up to 18).
This is why the pinout changed between Skylake and Kaby Lake CPUs - both only went up to 4 cores in the desktop market, but the latter had higher power requirements for the best models (with the change in pinout mostly being for extra Vcc pins). The pinout was changed again with Coffee Lake, and for similar reasons, but by the time the refresh hit, Intel had pretty much run out of reserved pins to convert into Vcc ones.
So given that Intel pretty much keep the same setup for 1 or 2 generations at most (the socket might be the same, but the pinout and supporting chipset changes), the only way they could increase the core count, clock speed, and power consumption over the likes of 9900K was to add more pins.
I said 8600k. Or an 8400. Or even an 8100. How is a 9900k not a worthwhile upgrade over them

AMD offers your hypothetical 100% but with a higher tier product. The 3900x is the price competitor of the 9900k and it doesn't offer your 100% increase. When you get to the point of paying 750+ for a cpu than you might as well buy a new motherboard.
Who said anything about games? Why are you changing your arguments just because they got proven wrong? Makes you look biased dude.How do you get much more? 33% comes from cores, 0% from IPC, almost nothing from SMT in games, 16% from turbo clocks. Also core to core latency is higher. In reality those calculated figures are even lower.
3900X easily offer over 100% increase, if comparison is against 6 core Zen+. 3950X launch price is $749 and it offers over 100% improvement even when comparing against Fastest Zen+.
And basically you're right, 9900K is so expensive too that better to buy new motherboard.

Does the 3950x offer 100% improvement compared to the 2700x in games? NOPE. So why does it have to be games when it comes to Intel?
You said it yourself, without even bringing HT into it 9900k is 50% faster than the 8600k. So according to your first argument, a worthwhile upgrade. With HT into the mix it's 100+% faster than the 8600k in anything that can use cores / threads. You know, exactly like the 3900x you mentioned compared to the 2600x.
So WTF are you talking about is beyond me. An outdated platform? Oh really, you realize that the z370 was realized in 2017. You know, between zen 1 and zen 2. So what platform would you have from AMD in the time? X370? That's not an outdated platform? Oh kay
Because single core turbo helps mostly on games. That's why. Single core turbo helps on games, SMT does not. On other way around, SMT helps outside games but then we must also consider base clock, not max turbo.
It's barely 50% faster and as AMD example shows, that improvement should be much bigger. 50% is just bare minimum to even consider. And considering high price and outdated platform, that is not worthwhile upgrade.
Z370 is outdated platform because:
1. It has not PCI Express 4.0
2. It lacks M.2 connection wired to CPU.
When it comes to X370, it has no 1. BUT it has 2. So even X370 is much better than Z370.
