At the same time though... as you mentioned yourself... the power draw...
Now, don't get me wrong, I personally never cared about power draw until it got stratospheric, at least, on CPUs. I remember the first time I actually was shocked at the power draw of a CPU and that was the AMD FX-9590. I remember shaking my head and thinking "I'll never buy a CPU that REQUIRES an AIO." and while the i5-12600K doesn't require an AIO (it's better than the 13th and 14th-gen CPUs that way), it still draws a good deal more than the R7-5700X3D.
The maximum peak power draw is higher for the 13th gen, that's true. But for 12600K and 13600K base power is the same, 125w. The CPU doesn't always draw a brutal amount either.
Looking at my i5 13600K in HW monitor, it mostly draws around ~20w when doing nothing special such as right now as i type this, or playing a video in VLC. Of course waving the mouse cursor around draws 45w because of course it does.
(Win11. Though maybe it's the custom mouse software by steelseries that is to blame. I use it for finer sensitivity adjustmets than Win can offer. steelseries GG software is bloated and mostly awful imo.
Or maybe we live in an age where it takes 6 CPUs running 4Ghz to move a mouse cursor around *sigh*)
I'm not going to try and stress the CPU now, even if it would be useful to know the average draw. But most of the time it is a completely reasonable 20-50w. Hops to 65w during a Steam update. Hovers around 55-70w during gaming. This is just a brief check, nothing thorough.
Still, a CPU that did the same work but drew less would over time result in savings.
It doesn't reach AIO territory, and it doesn't reach 125w or anything that would be considered shocking.
Not a scientific test, but power draw isn't shockingly bad.
Also, the 12th gen is inferior in efficiency to the 13th, not the other way around. 13th has a higer peak power not average.
How it compares to R7-5700X3D is another matter. Add the cost of the 600/700 platform, and i would not try to argue the LGA1700 is better. Only that it's not out of the running.
Since Intel has moved on, only price drops can improve things, and some late components if they show up. DDR5 RAM is one part of a LGA1700 DDR5 build that will improve. But that's minor.
AMD has free reign with the AM5 platform and that is it's biggest advantage. That and the gaming oriented performance of the X3D CPUs.
CPUs from that era like Sandy Bridge, Ivy Bridge and Vishera are still mostly usable today. By the same token though, the exact same thing could be said about the R7-5700X3D. The question is whether games in the future will be more cache-sensitive or clock-sensitive. The big advantage that cache offers is that it pretty much nullifies the need for faster (and thus more expensive) RAM.
No argument here. A hidden advantage of not needing faster RAM is that it avoids long boot times due to memory training. Bonus for the X3D.
there is a huge library of games made in the last ten years that could keep a gamer happy for a long time and online games are a joke with regard to hardware requirements so it really depends on what they want to do. These things are really hard to predict.
Again, agreed fully.
When someone says "dead platform", it means that there won't be anything new coming out for it and any upgrade of a core component will require the upgrade of the entire platform. AM4 has been called a dead platform for over a year now (but AMD hilariously keeps releasing new CPUs for it). I'm going to see just how long my AM4 platform is viable for because I have an R7-5800X3D, 64GB of DDR4-3600, an X570 motherboard and an RX 7900 XTX. So, you could say that I'm "living the experiment". 😉
I haven't really read the AM4 is a dead platform. As you say, AMD not only supports it but releases new CPUs~! for it. It's pretty ignorant to call AM4 dead.
LGA1700 is more "dead", but that is partly Intel's fault. Because they change sockets so much. The LGA1700 is also cutting edge. Funny that.
Part of the problem is also that tech moves on after 1-2 years on Intel's side, which is too fast for consumers. Maybe. Maybe not, because most upgrade after several generations, not gen to gen.
But you know all this.
Also, you're sitting pretty with your setup. That PC won't be knocked off it's perch for a long time i think. 2030? Who knows what will be out then.
Well, the thing is that if you're going to spend the money, for most users (not budget but not high-end either), AM5 does make the most sense. It's not much more expensive, it's going to make future CPU upgrades a lot easier and it has some of the most performant CPUs on the market today. Having said that, if I were to do an AM5 build from scratch, it wouldn't be with an R7-7800X3D, it would be with an R7-7700 because I'd want the 8 cores, the lower price and the included AMD Wraith Prism cooler (which is a fantastic cooler, especially considering that it costs $0).
Agreed. The final factor is the price. An Intel build may be competitive or even superior depending on pricing. AM5 will have the advantage of upgradeability which is hard to put a price on.
Good point about the R7-7700, and the cooler.
As for the prices, they can be annoying when they move up and down suddenly.
On the intel side, it's also annoying that non-K versions dry up very quickly and can be difficult to buy AND they cost more. They shouldn't, but the MSRP/RRP flies out the window very quickly.
This in turn changes what an "optimal" build should look like. As does availability outside the US.
That sweet AsRock z690 Extreme that sells for $130 would cost =>210€ in Europe. Not anywhere near the same value.
Finally, not sure i'd trust used parts. Drives, GPUs, PSUs all seem risky. Maybe not GPUs if it's one that 's unlikely to be used for mining. A CPU though, is probably a safe bet.
