AMD Mantle Radeon R9 290X CrossFire at 4K Preview - Is It All That It's Cracked Up To Be?

By: Anthony Garreffa | Editorials in Video Cards | Posted: Feb 12, 2014 1:03 am

Our Setup


We tested the new Mantle abilities unleashed in AMD's latest drivers on an Intel Core i7 4770K CPU at stock clocks, 16GB of Corsair Vengeance Pro 2400MHz DDR3 RAM, and SAPPHIRE's Radeon R9 290X Tri-X GPU.




We used Windows 7 with the latest updates as our OS of choice.


Once I had downloaded the drivers, I ran Star Swarm at 3840x2160 on a single SAPPHIRE Radeon R9 290X Tri-X GPU.



How We Tested Mantle


We tested our Mantle-enabled setup at 1080p, and 4K. This provides us with a high-end, performance resolution to start off with. We'll re-run the tests at 1080p with another article, where we'll also see how AMD's Mantle tech fares against 4K/1080p on Intel CPUs, and again on AMD CPUs.


Star Swarm - Star Swarm is a technical demo developed by Oxide Games, and is Mantle-compatible. It uses the "Nitrous" engine, which will power some upcoming next-gen RTS titles. Thanks to its Mantle capabilities, it can use render bigger battlefields, and many more on-screen units.


The improvements with Mantle on Star Swarm are huge, especially when a lower-powered CPU comes into play.
