AMD Toronto APU Will Feature Dual IMC - Both DDR3 and DDR4 Will Be Supported

An interesting update on AMD'due south Tornoto Platform has appeared. It would seem that AMD is going to allow DDR3 and DDR4 support simaltenously on this item platform. The leak source is Bitsandchips.it and they particular AMD'southward conclusion virtually including dual IMC support on Toronto APU. AMD Opteron APU Roadmap

AMD Toronto APU and CPUs will Include Dual IMCs for DDR3 and DDR4 Back up

The Toronto APU and CPU are part of the AMD Opteron platform and are going to feature Excavator cores. A previously leaked roadmap showed that the Toronto SoCs will either support DDR3 or DDR4 memory, but at present it would appear that they are going to support both thanks to Dual IMCs (Integrated Memory Controller). AMD has previously steered articulate of DDR4 memory partly because the Industry hasn't grown accustomed to it and partly because it costs an arm and a leg. Nonetheless, they seemed to have reversed that decision. The Opteron platform currently houses the Berlin APU and Toronto is the successor of the aforementioned with the adjacent revision of Bulldozer architecture. Both the APU and CPUs will have iv x86 Excavator cores.

Carrizo was supposed to have DDR4 Memory but this was abased (according to latest reports) due to the high cost of the retention in question. So why has AMD decided to give Toronto processors this benefit? Well the reasoning is simple. Fifty-fifty though DDR4 is expensive, the expense only applies to consumer markets. Server markets be on a very strict toll and value model and only the relative expense per performance increase matters to them. But put, the Server Market would exist indifferent to the expense that DDR4 entails. Another factor is the fact that DDR4 retention can back up higher retention densities while having lower power consumption than DDR3. These two factors are once over again something very important for the server markets that operate on a Performance-Per-Watt model. Finally, this would make the Toronto APUs and CPUs future proof for when DDR4 does become cheaper than DDR3 (around 2022). The source is too hopeful that we will be seeing stacked DRAM on the Mobility platform of Carrizo APU also, something which should have very positive effects on the performance of the side by side gen APU.
