WCCF Tech spotted the existence of an AMD Steamroller based APU in the Bionic research database. The engineering sample could be part of the upcoming Kaveri or Berlin server APU lineup, it seems to have a 1.8GHz base clock and a 2.3GHz Turbo clock.
It is reported on his blog that the sample is probably part of the Kaveri APU lineup and is still in engineering phase featuring Steamroller cores. The Steamroller APU has an ES code of 2M186092H4467_23/18/12/05_1304 which reveals some rather interesting information. The Steamroller APU comes with a turbo core clock of 2.3 GHZ with normal base frequency of 1.8 GHz, the other 1.2 GHz frequency is configured for the north-bridge. The graphics chip on the steamroller APU is clocked at 500 MHz and the part is known as the AMD1304.1 = “KV SPECTRE MOBILE 35W (1304) GPU which was revealed in the leaked catalyst drivers a few weeks back.
The ES code 2M186092H4467_23/18/12/05_1304 tells us even more. According to earlier observations (here and here), the four numbers in the middle part tell a bit about clock speeds. If the first one is not 00 (no turbo, see Kabini ES), it indicates a turbo clock of 2.3GHz. The “18? stands for 1.8GHz nominal frequency. I’m not so sure about the “12?. It could stand for 1.2Ghz North Bridge clock. Finally the “05? indicates a 500MHz GPU clock. The right part “1304? is the GPU code, which – thanks to earlier revelations – can be identified as AMD1304.1 = “KV SPECTRE MOBILE 35W (1304)“. - Citavai Blog
