R600 Gallium3D Now Has Compute Shaders Working With NIR

[schmidtbag]

There was a Radeon RX 460 from XFX 3 years ago (a power connector was required though). That's the most powerful AMD passive card to date if I'm not mistaken.

There are passively cooled GT 1030s too, which don't require a power connector. Slightly slower than the 460 but a hell of a lot faster than the 4670.
Don't forget about having more modern features, too.

Wasn't the software FP64 emulation thing reserved for the NIR-path only?
I believe when NIR gets more advanced all should be able to do GL 4.5

If you are still rocking a pre-GCN AMD Radeon graphics card on the R600g driver for the HD 2000 through HD 6000 series, you really ought to consider upgrading in 2020

You're offering a free upgrade? Where can I sigh up for free upgrade?

Modern iGPUs should be about on par with that 460, for people buying new systems. Definitely faster than a 1030.

I agree, at least if the memory is fast enough. RAM bandwidth is currently the bane of iGPUs.

if it just works for your workflow, e.g desktop, code, science, office use? Nope. Save money and resources, and use it another decade or two ;-)

depending on electricity prices you are unlikely to save money and resources by using 2-3 decades old chips

GL_ARB_gpu_shader_fp64 on the r600 driver is available only for select GPUs that have hardware FP64 implementation (Radeon HD 6900 and HD 5800 series). There is a software implementation of FP64, but it is currently used only by the Intel driver, see https://www.phoronix.com/scan.php?pa...64-Merged-Mesa. Thus all the other GPUs, including my 6670, are stuck to OpenGL 3.3.

if you don't really need fp64 you could override it via environment variable and get 4.0

I have a fan-less hd4670. It uses so little power, it needs no additional power besides that from the PCIe slot.

slot provides 75 watt

[pal666]

one ought to consider that the amount of energy and other resources used in manufacture, recycling and logistics to build newer parts and discard the old ones is quite significant.

all that is already part of price

I never understood why people always seem to ignore the big issues regarding wattage, such as fan noise and the heat dumped into the room. The cost of the extra wattage under load is often negligible for desktop users.

cost of wattage could be more than cost of product in the long run and cost of product is often non-negligible. noise is evil, heat can be controlled by air conditioner
