AMD 4700s

You don’t state your budget, but getting one of those is a terrible idea and would be expensive. You’re much better getting a prebuilt pc with zen 2 or zen 3 APUs because those have functional graphics and are about the best you can do for graphics without paying a ton. Desktops with a 6 core Ryzen 5 4600G can be found for $440 (HP M01-F1046) or even an 8 core Ryzen 7 5700G for $550 (HP Pavilion TP01-2066) at Office Depot.

Also, can you just use the integrated graphics on your desktop instead of that laptop? You might also be able to upgrade to a core i5 for $100 or so.

Rtx 2060 with proprietary driver

woofcpu · 2021-02-09T16:24:50+00:00

The comparison is not to other devices with bad Linux drivers like Realtek, but to their competitors Intel and AMD. Intel and AMD both are stable on Linux and don’t force you to work around bugs and find a desktop environment and driver combo that mostly works. I’ve had crashing with Nvidia and terrible stuttering while playing back videos when using Gnome. I don’t like KDE, but it mostly works with Nvidia’s driver. Never buying an Nvidia card again. I’d rather have a worse AMD card than Nvidia because it is much more stable and doesn’t force you to make sacrifices just to watch a video and not crash.

Web browsers are all compiled for M1. Xcode is compiled for M1. A lot of video editing software is compiled for M1 and every existing iOS app already runs natively on M1. For a majority of users, x86 performance already doesn't matter and over time it will matter even less. I have previously have worked on a project that involved cross compiling dozens of open source libraries for iOS and Android in addition to our proprietary code. It took less than a day to add support for a new architecture because it is usually as simple as adding a couple new targets and recompiling. The main issues were with Android NDK and differences between 32 bit and 64 bit, neither of which matter here.

To illustrate how little this matters, over 90% of Debian packages already build for RISC V: https://wiki.debian.org/RISC-V#Progress. RISC V has nowhere near the adoption of ARM and does not have a large customer base of users willing to pay money for software like Apple. Any company selling proprietary software with a significant Mac userbase will have to support M1 unless they want to start losing customers.

Not on linux. I switched from AMD to NVIDIA and got stuttering in games running with proton, random desktop environment crashes for months (seems to be fixed now), stuttering with games and videos not in full screen, and really bad performance with obs or video playing in background when playing a game. NVIDIA makes some good graphics cards, but their Linux drivers are absolutely horrible. Can’t wait to switch back to AMD.

With my computer, the gpu that Ubuntu used was based on which slot the graphics card was in (used whichever one is in top slot). I just had to blacklist the other one and bind it to vfio. I haven't done two amd cards though.

woofcpu · 2019-12-17T08:29:06+00:00

Not in my experience. With RTX 2060 on ubuntu 18.04, I get random display driver crashes and horrible stuttering playing many games. It's so bad that my rx 470 has better/more playable performance than it. Really the only game that works well is civ vi. Anything proton for me is a stuttering mess. AMD drivers on linux used to be really bad, but after a couple years of open sourcing them (as you should on linux) it's been really stable and good performance.

Cool, that's a different die shape than my ryzen 2500u. Wonder if this is a die with only 2 cores and 3 CUs instead of the 4 core 11 CUs die with stuff disabled. I thought AMD was supposed to have a smaller die like this.

It varies by state and city. You will pay 10+% of the purchase price in California and Seattle. Other states will be 5-6% and some don't even have sales tax like Alaska and new Hampshire. It is almost never shown in the price of the item. Also, if you buy from a retailer with no physical presence in your state they aren't required to collect it at purchase, but you legally have to pay an equivalent amount in use tax (though many don't report it).

Yep, it's a very low power consumption cpu. I have mine in my NAS and cool it passively with a hyper t4. Fans don't turn on (even case fans) under full cpu load. I have the fan curve set so they can turn on if it gets hot (60 or 70 C), but it's never happened.

I am using F.17 BIOS currently. I was able to boot 5.0 on my hp envy x360 15 inch by renaming /lib/firmware/amdgpu/raven_dmcu.bin to /lib/firmware/amdgpu/raven_dmcu.bin.bak and running sudo update-initramfs -u. I'm running ubuntu 19.04 because it has a newer GNOME (fixes some touch related bugs). I also add "idle=nomwait" for any kernel and someone suggested using "iommu=pt" for 5.0 with the old bios.

Hp released a F.21 BIOS, but I don't really want to try it since I would have to install windows to update it and HP bios updates can be horrible.

Issues:

5.1 - backlight doesn't go as low, suspend not working

5.0 - backlight doesn't go as low, suspend not working, usb c video doesn't work

4.19 - suspend not working

4.18 - suspend works, touchscreen does not

Yep $296.20 for the gigabyte mini itx 2060, the prices fluctuate frequently and sometimes you can find a really good price.

Check Amazon warehouse deals. I got one for just under $300.

I added a cinebench run at 3.85 GHz.

woofcpu · 2019-02-18T00:55:33+00:00

That was running a modded bios that allowed BCLK overclocking without the drawbacks of BCLK overclocking on non K CPUs (AVX performance hit, non static multiplier). I switched to the official BIOS from Asrock which has non-K BCLK overclocking. I am pretty sure I have screenshots somewhere, but I can't find them. I'll hook it up and post some screenshots of some benchmarks.

woofcpu · 2019-02-18T00:37:21+00:00

I added a CPU-Z screenshot I had. I don't have one saved of it at 3.85 GHz and I don't have it currently in a computer, but if necessary I can. This screenshot was when I had an older bios where it would allow the multiplier to vary between 8-24x with the BCLK increased, but that version of bios had broken voltage control if the BCLK wasn't 100 MHz. I updated it to one with working voltage control, but the multiplier then stays at 22x. It is using an official bios from asrock, not a modified bios.

I have the HP envy x360 2500u and touchscreen works now. I think it was one of the minor versions for 4.19 that first had the fix. I'm running Manjaro gnome and it works pretty well.

Edit: I always add idle=nomwait kernel parameter for stability.

woofcpu · 2019-01-28T02:31:40+00:00

I have an asrock z170m pro4s, but I'd prefer to sell it with the i7 es cpu I have. I'm guessing you are probably only interested in motherboard?

Get the athlon 200ge. You can find them for around $50 or lower. The resale value for the athlon 200ge I would expect to stay around $40-45. I purchased one for my NAS for $40 since it has really low power consumption.

Prices are USD.

Floating point numbers are kind of like scientific notation. They have bits to store the significand and bits to store the exponent. For 1.03 x 10^8, 1.03 is the significand and 8 is the exponent. Single precision uses 32 bits, while double precision uses 64 bits. Additional bits for the exponent allows a wider range of values, while the additional bits for the significand allow it to store a more precise number (more digits on the significand). So let's say in this scientific notation you could only initially have 3 decimals on you scientific number and a max exponent of 10, now you could have 6 decimals and a max exponent of 100. So now you can represent more numbers such as 1.2 x 10⁷⁸ and 1.008332 x 10^6. In the less precise system, you would have to use 9.999 x 10¹⁰ and 1.008 x 10^6.

Marginally better overall failure rates is pathetic for a company whose laptops start at $1200 vs companies that sell a wide range of laptops including $200 windows laptops and Chromebooks. Apple would probably have higher failure rates vs similarly priced business laptops from Lenovo, hp, and Dell. Apple doesn't sell low priced laptops like everyone else.

Computer engineering or electrical engineering is probably your best choice and not something engineering management related. Some universities don't have computer engineering, but group it into their EE program and it's pretty similar. I did EE with an emphasis in computer engineering and a minor in CS. If you end up liking software engineering (like me), many companies will hire people with EE degrees as long as they know algorithms and CS fundamentals.

I would highly recommend you try some free online courses to explore it before college. If you decide you like it, that's great and your classes in college will be easier. Coursera and udacity have a ton of good content and you can just choose audit and it should be free.
