AnandTech is taking a close look at the comparative performance of the storage subsystem on the AMD 890GX and Intel X58/P55, specifically the performance of a SATA 6G Crucial RealSSD C300.  AMD has gone for native support of SATA 6GB/s, the controller is a part of the 890GX chipset and its PCIe 2.0 lanes.  Intel uses a Marvel add on chip in some cases, if they did not then support for SATA 6GB/s comes from a PCIe 2.0 add in card. 

With two very different ways of handling the transfer of data, find out what the strong points of each and more importantly which offers the fastest performance by reading their full article

“All performance improved, but we’re still looking at lower performance compared to Intel’s 3Gbps SATA controller except for random read speed. Random read speed is faster on the 890GX (but slower than X58).

The best part of it all is that I no longer had to disable CnQ or C1E to get this performance. I will note that my performance is still lower than what AMD is getting on its internal reference board and the performance from 3rd party boards varies significantly from one board to the next depending on board and BIOS revisions. But at least we’re getting somewhere.

In testing the 890GX, I decided to look into how Intel’s chipsets perform with this new wave of high performance SSDs. It’s not as straightforward as you’d think.”
