Default ATI already using 5GHz GDDR5

Amid the chaos related to the M97 announcement, AMD has slipped in an interesting bit of information yet to be acknowledged by the official specifications. In the product images from AMD's PR department, the Mobility Radeon 4860 MXM module is sporting 5GHz GDDR5 memory modules from Qimonda. The exact part number (IDGV1G-05A1F1C-50X) can be clearly seen in the image below. The last number 50x represents 5GB/sec per pin or 80GB/sec for a bus-width of 128-bit for the Mobility Radeon 4860. It is amusing that this could potentially mean that the M97 could have the highest memory bandwidth for any mGPU, comparitively the Geforce GTX 280M & the Mobility Radeon 4870 have a memory bandwidths of 60.8GB/sec and 56.8GB/sec respectively.
