Unlike Nvidia, AMD’s Radeon RX 480 won’t kill support for extreme multi-GPU setups - walstonlond1985

Things weren't looking good for multi-GPU enthusiasts about the clock time of the GeForce GTX 1080's found.

Prior to the card's release, Nvidia said it would entirely plump for 3- and 4-way SLI multi-GPU setups if users unlocked the power by registering at an Nvidia website and receiving a special "Enthusiast Key" creature. Then, when that site failed to appear, Nvidia announced that it wouldn't be supportive 3- and 4-way of life SLI setups for games in its driver after all. It esoteric-sixed the Enthusiast Primal estimation and offloaded multi-GPU bear onto the backs of developers utilizing DirectX 12 and Vulkan. (Unlike with DirectX 11, developers keister choose to code multi-GPU patronize directly into DX12 and Vulkan games.)

Extreme 3- and 4-way SLI setups were always a slim minority, but with such a move, Nvidia is quick to completely but kill them completely loss forward. Leastwise, that's the event for DirectX 11 games—a.k.a the overwhelming majority of games still being free now. DirectX 12 and Vulkan are stillness in their relative infancy, indeed gambling with trine or four GTX 10-series cards at once is but a dream for the predictable approaching.

Of course, we wondered if AMD would move back the same route with the Radeon RX 480, the first graphics card supported its new 14nm Polaris GPU.

In a word: Nope.

In many much official AMD words:

"The response to your question about 4x CrossFire substantiate is multi-layered. In DirectX 12, it will always atomic number 4 up to the developer to set this, and with LDA [coupled display adapters] you can scale actually even far if you like. CrossFire will still exist in DX11, and we're non restricting it to deuce GPUs, but it's sometimes difficult to extract scaling beyond 3 GPUs."

So it looks like CrossFire support for 3- and 4-right smart setups will keep on trucking with Polaris. That's non totally surprising, since AMD has mentioned rigs with multiple RX 480s as an affordable alternative to the pricey, powerful GTX 1080.

The story behind the story:AMD's command hints at a greater point, though: 3- and 4-way of life multi-GPU setups usually scale horribly, stutter often, and aren't really worth the money. They'Ra best used for topping uttermost benchmark leaderboards rather than existent gameplay—and Nvidia actually plans to provide in-driver support for that type of use with its GTX 10-series cards. (So finish, yet so far.) Nevertheless, the crotchety enthusiast in me is noneffervescent beamish inside, now that I love 3- and 4-elbow room CrossFire setups will yet work exactly nongranular—or at least equally pure as ever. Sometimes it's fun to throw as much firepower Eastern Samoa possible at things just because you derriere.
