It's not about heat, more probably vendors have a contract with Intel that makes Intel parts more expensive if they are not bought exclusively (it will be worded differently because Intel already got sued for this practice).
I recently bought a Thinkpad E495 with a Ryzen 3700u and thermals are just fine. The surface barely heats up under sustained load. The E series is more budget, though. But the T495 (14") or X395 are of higher build quality (and price) and also have Ryzen 3x00u CPUs.
- snvzz 7y agoTyping this on my x395 (with 3700u) and can confirm these are really well made laptops. Linux support is excellent. Openbsd is good but doesn't support this generation of wireless cards yet, which is quite inconvenient; next version perhaps.
- yoloClin 7y agoHow is graphics performance / functionality? I've only ever really dealt wit nVidia and Intel graphics, and highly prefer intel due to tearing fixes. I'm not a gamer, but do need at least basic hardware acceleration for X rendering etc.
- chupasaurus 7y agoIntegrated Vega full support landed in June 2018 (kernel 4.17, Mesa 18 for 3D), as long as you have these or newer and a firmware for your card in the system — you'll get full acceleration. I've been running Debian Testing on 2400G since 04/2018, where I had to put firmware and compile the kernel with the config changes to enable the support, but it was already in kernel tree nonetheless. It's out-of-the-box since 07/2018, way before the release happened.
- snvzz 7y agoAt least on Arch, X doesn't even start 4.19 (linux-lts package), but works fine on 5.2+ (linux package); probably also in some kernels in between, but I only bought the laptop recently. Likely specific support for 3700u was introduced at some point between these two kernels. AIUI 5.4 is meant to become the next LTS, so it won't be an issue going forward.
- chupasaurus 7y agoAMD added support for Raven 2nd gen APUs in 4.20.
- snvzz 7y agoThat might be it! Thanks.
- yoloClin 7y agoSweet, does that mean that there's no binary drivers (eg nvidia-drivers vs nouveau)? Have you had any issues you suspect may be driver / gfx related?
- snvzz 7y agoThere's the amdpro drivers, which nobody uses; they're partially open source, as I understand it. The point is that AMD releases detailed documentation for every GPU they sell, and thus it's very easy for mesa to support their hardware; AMD themselves also contribute code to Mesa, of course. This is in contrast to NVIDIA, which even uses encryption and signatures to twart nouveau efforts. I avoid NVIDIA entirely, for this reason. I haven't had issues so far. Life has been good, same as with the vega 64 on my workstation.
- chupasaurus 7y agoAFAIK There is no AMDPRO drivers for Ryzen APUs.
- snvzz 7y agoGPU Accelerated graphics (2d, 3d and video codecs) on both Linux (5.2+, probably earlier) and Openbsd (6.6+), with open source drivers (kernel DRM, userspace mesa3d and xf86-video-amdgpu). If you get tearing, try: xrandr --output eDP --set TearFree on To enable the anti-tearing workarounds. This shouldn't be necessary on a modern composited desktop, but I do need it with a simpler i3 setup, to not tear videos on youtube. Mpv seems to not need it either.
- yoloClin 7y agoThanks, that might be helpful given I run OpenBox / qTile :)!
- mcv 7y agoInteresting. I haven't looked much at the E495 and T495, but the X1 Extreme, P1 and P73 were not available at all with Ryzen CPUs.
