  The Sapphire Pulse Radeon RX 7700 XT Gaming 12GB is really good value, mid range GPU right now https://www.centrecom.com.au/sapphire-pulse-radeon-rx-7700-x…

  A lot of reviews on the web don't rate it because it was released at a much high price point, however prices have come down a fair bit to the point that it's now an easy $80-$100 less than comparable GPUs.

  12GB memory makes a huge difference over 8GB, which is more or less the standard otherwise in this price range.

    Thank you for sharing that, a friend of mine is running a RX 7900 XTX which it just a bit too much for what I need so I was considering going with an inferior GPU.

    Thanks again.

  There's a big mix of overthinking and underthinking going on in your post. I'd figure out what you need and/or what your budget is, because you're a bit all over the place with really fast yet wanting low power and cheap. Building cheap and needing to replace in a year isn't what you want to do. Upgradeability might be important to you (a 5700X system is great bang for buck, but it's the end of the AM4 platform).

  I do lots of CLI tasks, 3D printing and CAD so a fast PC is a must.

  Is your current 5800H up to task for this stuff?

  CLI tasks and 3D printing aren't exactly CPU heavy, CAD on the other hand can be but depends on what you're actually doing. The big question though is whether an AMD CPU is best or if any of the programs you use would work better with a nVidia GPU.

  A CPU with low DTP ( Thermal Design Power) would be awesome. My current Ryzen 7 5800H is TDP 45W so it runs very cool like around 50c

  That sounds like you're not pushing the system very much. 45W is a lot in a laptop, it's nothing in a desktop with a lot more space to dissipate heat. Is it running at 50C under load? Is the CPU throttling?

  Motherboard: You can have the best CPU of the planet but if the motherboard doesn't have enough PCI-e lanes, things will be running half of its performance like using NVMe X slot means PCI-e 16x now runs as PCI-e 8x for example.

  This is basically a non-issue, some older boards had problems with budget GPUs.

  PSU: No much secret either, check the components power consumption and add an extra 10% or something.

  Do no cheap out on the PSU. If the PSU goes then likely the rest of the PC will go with it, but also if power isn't consistent you'll bring in instability issues. There's a lot of difference between a no-name PSU and a good one of the same wattage.

    Yeah, my post was all over the place.

    I spoke with a friend running an insane 100% AMD setup to get my head around this, will follow his paths even so it's a bit overkill for me atm but totally future proof. He is running Ryzen9, RX 7900, 1000W, you name it and most importantly, 100% Linux support.

  what is your budget ? I would get an Nvidia card if CUDA helps for these tasks.

  If I were you, I will go for an Intel + NVidia system. If budget is enough, go for i9-14900K (or 13900K) + 96 GB DDR5 + used RTX3090 or above. You won't have to upgrade for a while

  It would be awesome if you have experience with Linux and your PC is running Linux over Windows.
  I am running Linux Mint Cinnamon without any issues, RTX3050Ti and Intel WiFi6 was recognized after updating the kernel.

  It depends, there are places to use Linux and other places to use Windows. I have recently installed WiFi 7 card on Linux 6.8.1 and still couldn't get AP mode to work lol

    This isn't my first rodeo on Linux, the OS I run just works without drama, I hate Windows and Intel is overrated like a lot.

    I spoke with a friend running Linux on his Ryzen 9, RX 7900 XTX, Aorus mobo, 1000W PSU and an insane Noctua, he is playing games with 3 digits FPS.

    I'm not after gaming but the performance on that system is insane so I'm thinking in copycat his setup and won't need to upgrade anything for like 10y haha

    He did mentioned about CUDA, DLSS, I'm okay giving up on that to have a decent stable system.

      I hate Windows

      I was like you back in 2003 and only used Linux 2.4, but later I understood that we need to use different OS for different tasks :D

      There are a lot of tools which use Intel MKL (kinda defacto in most cases) for maths calculations (ex: CAD), which might have a performance impact on AMD.
      https://community.amd.com/t5/server-gurus-discussions/perfor…
      Personally I only had one PC with AMD because that had the best performance to price ratio at the time. But then moved back to Intel.

      Also, AMD GPUs are not suitable for much other than gaming due to lack of CUDA (used for most ML, engineering applications etc), NVENC etc
      Their drivers were notorious back then I don't know how they work now. Most people are using AMD GPUs on Linux due to open source drivers, but you can use nVidia propitiatory drivers as well.

      So, if you are looking for a workstation, where you are going to play some games, I would still get a Intel + nVidia

        Linux itself used to be dogshit, I managed to get kernel panic trying to compile driver for my Nvidia card back in the day.

        I used to run Ubuntu Linux for around 10y or so but it has become a Windows version within the Linux world.
        I have been running Linux Mint Cinnamon that is as solid and stable as Debian which is what I run my homelab stuff like kubernetes and alike, it just works.
        For it to recognize my WiFi6 and GPU all I needed was the the latest kernel.
        Linux is so much different now than the 90s, I love it, I can run whatever, no virus drama, no BSOD drama, no resources being taken by the system for no reason, no driver drama.

        My job allows me to use Linux which is this Legion gaming laptop, love it.

  You realise don't you that a Ryzen laptop CPU doesn't use less power because its more efficient, but because they slowed down its maximum speed so it uses less power. Doing the same work, they'll use the same amount of power and generate the same amount of heat, but because the laptop one has a lower maximum clock speed the maximum amount of power it uses and therefore the heat it generates is less, so they can put it in a little laptop case with a little laptop fan.

  Some CPUs have a configurable TDP - cTDP. If its implemented in the BIOS by the motherboard manufacturer you can set the maximum amount of power it can use, which sets its maximum clock speed to do that. So, for example the Ryzen 8600G can be set to 65W max, or 45W max. And there's a 8600GE that has an out-of-the-box TDP of 35W. Then there's 7760 (I think) which is essentially the same CPU, which is the laptop version in a laptop package. In the case of those CPUs, its quite handy to being able to set the TDP because, without a separate GPU, you can run a really tiny power supply.

    Thank you so much for the reply and explaining how the TDP works, I sort of expected the laptop to be behind the low TDP but didn't know how.

    I spoke with a friend yesterday and my whole plan has been deleted haha

    He built an 100% AMD PC, Ryzen 9 16/32, RX 7900 XTX, 1000W PSU, Aorus mobo, you name it.
    I don't really need a PC that crazy but those parts aren't too much or whatever that means so I might copy cat his setup. I might grab an inferior GPU.

    To make things better, he is running Linux which AMD is 100% supported on Linux, he is running Cyberpunk, Doom via Steam on max with 3 digits FPS.
    If I copycat his PC setup, I won't need to upgrade anything for the next 10y lmao so why after talking to him I'm willing to overspend now.

    As far as my noob experience goes, the system will only pull its total power consumption if requested so for example if I'm running command line tasks, the power consumption will go nowhere but when dealing with my 3D printer and CAD stuff the power consumption will go brrrrrr and I'm okay with that.
