Modern CPUs have 512bit registers, and don’t need bigger memory addresses. Not sure what the issue is.

It’s the memory controller and cache subsystem. Series S talks directly to gddr6 and doesn’t need nearly as much die space as all the L3 and big DDR5 memory controllers as the Ryzen APU in the steam deck.

Yes, a 192bit bus will be non competitive even with gddr7.

I upgraded to a 6950xt to play at 4k above 60fps and it works great. Couldn’t be happier. Even ray trace in most games, except a few of the heavy hitters.

That’s right the 390 was a 512 bit card. And it was a beast. I had a 7970 that lasted for a long time as a capable GPU.

My favorites were the 512bit bus monsters from 20 years ago. With raytracing being so memory and power intensive it kills me that we haven’t gotten a monster like the 8800gtx again

You’re running your ram out of spec for 4 sticks probably, if you’re getting errors you would probably be better off with 2 sticks at 16gb each.

You can test this by just running on the A slots for each channel and running 16gb for a bit. You should see errors go away, if they are happening at stock with xmp

I ran one for a year and had no stability problems. Hot spot temperature issues heh, but no crashes. Fewer even than your normal nvdkm.dll crashes Nvidia has always had.

No it’s because the 5700xt has to run mesh shaders on their vertex shaders and pixel shaders and probably needs to go back and forth a bunch. Mesh shaders take over vertex shaders and do some pixel shading stuff. My guess as to why RDNA1 gets hit less hard than Pascal is because of the async compute performance advantage which lets them do the inefficient way a lot more parallel.

This is all supposition based on what a mesh shader is. Im actually surprised they will run on a vertex shader at all.

Running LCDs/oleds at lower resolution doesn’t reduce their power requirements because they are still powering the backlight and every pixel. It will only (very) slightly reduce the framebuffer usage and possibly gpu power. Very slightly.

Reducing the brightness is the only real way to reduce screen power requirements.
