I doubt an iGPU will ever be viable for gaming simply because it has to use DDR memory instead of GDDR

- bick_nyers 3y agoThrow some extra 3D cache and go to quad-channel memory and I think that would be enough for a lot of people.
- dragonwriter 3y agoIs there any reason a new CPU (and iGPU) generation couldn't use GDDR?
- Dalewyn 3y agoBecause some people will screech that the RAM is soldered and can't be upgraded; the laws of physics dictate that DIMMs degrade the signals too much for the speeds desired. Of course, if Intel puts more emphasis on ARC iGPUs I wouldn't be entirely surprised to see mobos come out with GDDR VRAM soldered on. Some people will definitely still screech, but they aren't important.
- dist-epoch 3y agoBasically the number of wires going to the memory. On discrete GPUs memory is placed in a circle around the GPU chip, each memory module connected with individual wires.
- dragonwriter 3y agoSo, my impression is you’d lose replaceable memory, and the total practical memory would be lower than the maximum practical RAM + VRAM in situation with a CPU with (LP)DDR and a dGPU with GDDR, but intuitively it seems like you’d get better performance than with an iGPU otherwise and still save on cost/performance (though cap performance lower) than a CPU + dGPU setup for lots of use cases.
