Description

I've found threads dating as far back as 2017 about dropping support for GCN 1 AMD GPUs, however the requirements page still lists "AMD: GCN 1st gen and newer". Could the description please be updated? I'm sure I'm not the only one to make a purchase based on the requirements and be left with no selection for OpenCL.

Also, on the same note, could there be an indication that Intel's "Haswell" CPUs are the i3-/i5-/i7-4xxx CPUs for convenience's sake?

Event Timeline

GCN first generation is still officially supported using current drivers. If it doesn't work, please create a bug report.

Somebody from the GPU team may correct me, but every integrated GPU that is Haswell or later as listed here should work properly as well, if it is fulfilling the additional requirements:

Minimum

  • 64-bit dual core 2Ghz CPU with SSE2 support
  • 4 GB RAM
  • 1280×768 display
  • Mouse, trackpad or pen+tablet
  • Graphics card with 1 GB RAM, OpenGL 3.3
  • Less than 10 year old

Yes, we've made sure HD4000 series are still working in Blender 2.90. There was some discussion about dropping support for certain architectures, but we have been able to get them working when we released 2.80. Not sure if they are still working as we don't have access to these architectures.

In the future we might need to drop them due to vulkan support, but not now.

I just noticed that you wrote the following:

The minimum requirements are for running Blender, GPU rendering with Cycles has higher requirements as stated on the same page:

These requirements are for basic Blender operation, Cycles rendering using the GPU has higher requirements.

The linked page in the manual states:

AMD
OpenCL is supported for GPU rendering with AMD graphics cards. Blender supports graphics cards with GCN generation 2 and above. To make sure your GPU is supported, see the list of GCN generations with the GCN generation and supported graphics cards.

AMD OpenCL GPU rendering is supported on Windows and Linux, but not on macOS

I see, my fault, then.

Though, interestingly enough, I can use and render on my old HD 6770 (better than on the processor), which is two generations before GCN, and I have not been able to detect issues so far. Aside from speed, obviously. So if those are the minimum specs to run Blender at all, why isn't Tera Scale 1-3 listed, assuming Blender only needs OpenGL 3.3?

As for the Haswell processor, it works as expected on my i3-4150, my point is that it'd be more readable if the the requirement was also listed as "iX-4XXX" besides the codename, since it is easier to find (and remember) the "number" than going through the additional step of also finding whether the number corresponds with "Haswell" in that large table.

@Mit Iks (MITX) I'd be surprise if Blender lets you select a Radeon HD 6770 as OpenCL render device in the preferences, because that shouldn't work. If you just meant for running Blender, there are GPUs capable of running Blender that are below the minimum requirements, but we don't officially support them. TeraScale 1 to 3 GPUs might be able to run Blender, but it's not guaranteed. It is likely that you will experience graphics glitches or even crashes due to bugs and oddities in the older graphics drivers.

Listing specific processors would be possible, but that would mean we'd have to list every CPU. Avoiding a gigantic list of devices on the requirements page was in my opinion the right choice, but I can see your point.
