In today's day available latest CPU AMD Opteron 6300 series, exploitation of propositions Opteron 6200 until today uncommitted on the market like what we have seen in recent weeks in a desktop environment with the debut of the latest processor editions of the FX series, Opteron 6300 CPUs acquainted in the server and workstation Piledriver architecture that takes the place of the Bulldozer adopted previously.
It is an development of Opteron processors, surely not a revolution: it continues unaltered the G34 socket for connection to the main board, so you can upgrade to the latest CPU also the systems so soon on the market, and does not alter still the production technology which continues to be a 32 nm with production entrusted to GlobalFoundries.
The transition from architecture Bulldozer to that Piledriver is concretized in some performance optimizations that allow to obtain an increase of the IPC, instruction per clock, with respect to the architecture of the previous generation while maintaining unchanged the maximum number of cores available.
We continue this slide, provided by AMD with the technical documentation of the next generation FX processors to better summarize what were the innovations introduced by AMD Piledriver. The main architecture, we point out again, is in any case continues the similar: each module Piledriver views the combination of 2 units of integer calculation that share a drifting-point L2 cache is 2 Mbytes.
Downstream of the modules we find a unified L3 cache in the amount of 8 Mbytes, for up to 8 cores or 4 Piledriver modules integrated into each day. The next chart summarizes the number of cores and the dispersion of Piledriver modules available in 4 editions of Opteron 6300, so as to good understand what the diagram of operation of these processors.
The Opteron 6300 are all obtained by combining two died on the same package processor, which explains the presence of a quad channel DDR3 memory controller with two channels integrated into each of the two die.
This design, borrowed from those of the processors Opteron 6200 also those confronted by AMD Opteron 6100 in 2010, gives that the communication among the 2 dies happens via a dedicated HyperTransport link; the same type of connection that is then used in communications among the various socket on the motherboard, with a maximum of 4 sockets that can be used simultaneously with Opteron 6300.
There are various editions of Opteron 6300 CPU AMD makes present to its client by today the highest number is that of the models with 16 cores, while 2 editions with 12-core architecture with as many as 8 cores. To close the give only one model, the Opteron 6308, with quad-core architecture that balances the cut back number of cores with a clock oftenness higher than the other propositions, establishing to be concerning for apps insensitive to the number of cores and the identical clock rate of the CPU.
We find, like the proposals Opteron 6200, the Turbo Core technology which allows to obtain an automatic overclocking of the CPU when the operating specifications are kept within certain values for temperature and instantaneous consumption: in this way the average instantaneous frequency is indicated in the table as Clock Turbo all. Even with all the cores used at 100%, while as soon as the application uses only part of the core available to the frequency increases until it reaches what is referred to as Clock Turbo max.
The next table summarizes the technical features of the CPU Opteron 6200 series, established on Bulldozer architecture and are compatible with the similar platform utilized by the CPU socket G34 Opteron 6300.
The technical spec of the maximum in terms of number of cores, clock frequency standard, Turbo and Turbo Max, are in fact coordinated amongst the two families of Opteron CPUs and previous generation.
It does not alter any more than the TDP of 115 watts in standard, 140 Watt in the SE to higher function and 85 Watts for the mutations HE consumption lower, as the official price lists tend to be slenderly lower with the CPU Opteron 6300 in comparison with the Opteron 6200 models of the same clock frequency.
For these latest AMD says betterments in consumption and an raised in average function accomplished thanks to the new of its Piledriver and not with raised in clock frequencies In general we can expect performance gains quantifiable than in 5 while consumption according to what occurred with the FX family of desktop processors based on this architecture should essentially remain unchanged.
As indicated above, therefore, we are facing an evolution and certainly not to any radical changes to report in this sense, the decision to offer Opteron CPUs in 6300 lists slightly lower than the Opteron 6200 family of models of the same clock frequency.
It remains now to understand when AMD will also introduce new versions of the Opteron processor family 4300, then think for C32 systems and intended to servers and workstations with 1 or 2 processor sockets: in this case we find mirrored versions to those based Opteron 4200 of architecture Bulldozer, Piledriver architecture with innovations and models with up to 8 cores per socket.
