If you're looking in that price tier, I'd go AMD where the deals are much better. A 6700XT is basically the same price as a 3060 and is a substantially more powerful card.

When crypto was brand new, mining started off using CPUs. However, that quickly gave way to the creation of ASICs (application-specific integrated circuits), which are purposely designed and built for just crypto mining, and often one specific hashing algorithm (like the one bitcoin uses).

There was a big belief in the community at the time that the intention of crypto should be "one PC, one vote". The ideal network was secured by a shitload of people using their PCs to mine and each person would have a vote in the next block chosen. ASICs eliminated that possibility because they were orders of magnitude better at mining than even a crazy high-end desktop PC. Regular people couldn't contribute to mining power significantly anymore, it was all about who had the best/most ASICs. That's why although bitcoin is the largest cryptocurrency by far, it doesn't directly affect consumer PC components when its mining becomes more/less profitable.

Enter Ethereum. This shook up crypto in many ways, one of which was to make the network less centralized, by having a shitload of miners rather than a few with mega expensive mining rigs. Now I don't know enough about the technicals here but it was intended to be ASIC-resistant, and for that to happen it doesn't use just one single hashing algorithm. So you can't build a circuit specifically optimized for one type of math problem, you need to be good at a bunch of them. Basically you'd need an all-around better CPU. But for whatever reason, GPUs tend to better at crunching large amounts of numbers like you'd need for hashing algorithms. The analogy I've heard is that a CPU is like a fighter jet, and the GPU is like a cargo ship. The jet will get there much faster but because it can't carry much, the ship will get 10,000 tons of cargo to its destination much sooner.

Of course, it didn't take long before people started buying a bunch of GPUs and hooking them together for mining. But at the very least, if you wanted to have 10x the hashing rate of the best GPU available, you had to spend ~10x as much on GPUs. Compared to bitcoin, where 10x the spend could get you thousands of times more power.

The operations that are needed to calculate (or rather guess) the keys required to mine new blocks on the blockchain are best run on graphics cards, hence the demand created by crypto, and the price hikes that came with it.

I’m not sure why that is the case though, maybe someone can explain how a GPU is better suited for the job than a CPU. I think it somehow has to do with CPUs focusing on parallelization and energy efficiency in recent years, while GPUs are more like raw power work horses.

Your economic recommendation is… purchasing GPUs that are the price of an entire console, and then for 4k, recommending me cards that cost even more?

I understand you had helpful intentions, and perhaps I should have clarified better, but the cost of pc building (and manufacturers actively choosing to reduce production/withhold stock to keep prices high) in this economic climate is the entire problem/reason why people like myself are hesitating to build even when we want to, and why PC CPU shipments are in decline.

Suggesting I purchase even more expensive parts than I was even planning for the build in the first place is kind of missing the point (though to be fair I suppose I never posted the intended build).

An RX 5700? Not at all. Those are RDNA2 graphics and Zen 2 (3700X, not 2700X), if I recall correctly (I looked it up once upon a time, but don’t remember the exact SKU it was similar to) it’s more like a 6700XT/6800. In raw performance, a 3060Ti would actually be pretty close.

PC is still better in my personal experience, but the consoles are unbeatable value right now and there’s no need to act like they have worse hardware than they do.

Edit: looked it up and the core count is in between 6700XT and 6800, but it’s also clocked lower so it probably performs about in the middle given the slightly lower overhead and higher optimization that you can get on a console.

Current consoles are equal to 3800 amd and 2080 nvidia

The CPU’s in consoles are closer to 3700x.

5800x3d would be better for cpu.
