They are well 1.4 billion transistors that will make up the Ivy Bridge solutions, we believe in the quad-core implementation. This is a quantity of more than approximately 20% compared to that of Sandy Bridge solutions currently on the market: it is conceivable that this increase is mainly due to the innovations implemented in the GPU part, that in which we expect major innovations.
Ivy Bridge maintains a structure similar to that of solutions Sandy Bridge and this is evident as early as the socket connection, which remains the LGA 1155. We find then on a single die CPU and GPU components, linked together through the ring bus. Do not miss Controller PCI Express and DDR3 memory controllers, dual-channel type.
Among the main changes implemented by Intel in future architectural solutions Ivy Bridge signal the presence of a specific L3 cache for the GPU component, an element that was unified with the other hand, the Sandy Bridge CPU solutions. This approach would reduce the resources in terms of bandwidth internal bus to the processor of the ring, bringing direct benefit as a reduction in consumption.
Changes were also implemented technology to Intel's Quick Sync videos, which would use the component inside the processor to GPU to speed up conversion and Trans coding of video streams. This feature was first introduced in the proposed Sandy Bridge with good performance results, but unfortunately limited to a small number of such scenarios. Ivy Bridge with Intel on the one hand wants to overcome these limitations, the other trying to further improve the conversion time.
We also find Digital Random Number Generator and Supervisory Mode Execution Protection features that enhance the approach to data security inside the processor.
Deserve a specific mention of the information provided by Intel with regard to over clock these processors. The memory controller has been amended to also accept the use of memories up to DDR3 2,800 MHz maximum clock , with increases in clock frequency that will be in steps of 200 MHz. Sandy Bridge, by way of comparison, the maximum clock frequency of the memory is configurable to 2,133 MHz frequency will be increased by the multiplier selected as the most, going from 57x to 63x today, Intel did not specify, but we think it plausible that this will happen Ivy Bridge CPUs only unlocked by default, so belonging to the K-family .
Various internal optimizations related to the reduction of the consumption function were also implemented in the memory controller. Specifically this component, the CPU intended for mobile systems, will also use low-voltage DDR3 (DDR3L) as well as implement optimizations that reduce the active power.
We have already had occasion to talk about the TDP configurable, another characteristic of specific solutions for the mobile segment Ivy Bridge that will have levels of TDP differentiated depending on the type of cooling system that is coupled to the processor. Intel indicates the TDP with 3 different ranges: nominal, configurable lower TDP (down CTDP) and upper configurable TDP (CTDP up). The first is the standard value for the CPU and the second is a lower value to allow mobile devices to further reduce consumption. The third, finally, is worth more than that requires a cooling system is adequate but that gives you higher performance levels. The TDP variable is independent of the Turbo Boost technology, which continues to be present regardless.
Various innovations, then, are those that will be built by Intel in Ivy Bridge, far more than we would have expected considering that with this architecture is the real novelty is represented by the production technology to 22 nanometers. This is also why Intel refers to as a tick + Ivy Bridge, that is an update that is higher than normally seen in the past by adopting a new production process.
