@@ -18,8 +18,9 @@ FIJI Family of dGPU, and has expanded to include the Hawaii dGPU Family in ROCm
ROCm 1.3 expands this support to include the Polaris Family of ASICS.
#### Supported CPU's
ROCm Platform Leverage PCIe Atomics (Fetch ADD,Compare and SWAP, Unconditional SWAP, AtomicsOpCompletion) To find out more about [PCIe atomics](https://github.com/RadeonOpenCompute/RadeonOpenCompute.github.io/blob/master/ROCmPCIeFeatures.md) which are only supported on PCIe Gen3 Enabled CPU's and PCIe Switches like Broadcomm PLX. When you install your GPU's Make sure you install them on real PCIe Gen3 x16 or x8 lanes directly on CPU's Root I/O controler or PCIe Switch directly attacted to the CPU's Root I/O contorler. We seen many issue with Consumer motherboard support Physical x16 Conecectors, but the elecitical only conected at PCIe Gen x4 off the southbridge PCIe I/O controler.
* Our GFX8 GPU's ( FIJI & Polaris Familiy) use PCIe Gen 3 and PCIe Atomics (Fetch ADD,Compare and SWAP, Unconditional SWAP, AtomicsOpCompletion) To find out more about [PCIe atomics](https://github.com/RadeonOpenCompute/RadeonOpenCompute.github.io/blob/master/ROCmPCIeFeatures.md)
* Our GFX8 GPU's ( FIJI & Polaris Familiy) use PCIe Gen 3 and PCIe Atomics
Current CPU which support PCIe Gen3 + PCIe Atomics are:
