Nyní probíha IDF a Intel poodhalil pár věcí ohledně Haswellu. Takže:
Since the world's largesty chipmaker has demonstrated Haswell chips for a number of times already, this time the company will likely show it working. Unfortunately, it is unlikely that the company will discuss performance benefits of the new micro-architecture in details.
Intel Haswell microprocessors for mainstream desktops and laptops will be structurally similar to existing Core i-series "Sandy Bridge" and "Ivy Bridge" chips and will continue to have two or four cores with Hyper-Threading technology along with graphics adapter that shares last level cache (LLC) with processing cores and works with memory controller via system agent. The processors that belong to the Haswell generation will continue to rely on dual-channel DDR3/DDR3L memory controller with DDR power gating support to trim idle power consumption. The chip will have three PCI Express 3.0 controllers, Intel Turbo Boost technology with further improvements and so on.
On the micro-architectural level the chip will be a lot dissimilar compared to available solutions. It is believed that the new Haswell x86 micro-architecture will be substantially different from existing, which will enable further scalability and performance increases. Besides, Haswell will support numerous new instructions, including AVX2, bit manipulation instructions, FPMA (floating point multiple accumulate) and others. The new graphics core based on Denlow architecture is projected to support such new features as DirectX 11.1, OpenGL 3.2+, to be substantially more powerful and to be certified to run numerous professional applications.
Intel Haswell chips also implement a number of aggressive measures to trim power consumption, including power aware interrupt routing for power/performance optimizations, configurable TDP and LPM, DDR power gating, power optimizer (CPPM) support, idle power improvements, latest power states, etc.
Now Intel tells its partners to expect that Haswell should end up at least 10 percent faster than Ivy Bridge based cores at the same clock. These numbers are based on pre-silicon projections that Intel always does before it gets the working prototype back, but since we are some month away from the IDF 2012 in San Francisco, we are quite sure that we will see Haswell again, much closer to its final design, and we even expect to see Broadwell prototypes to hit at least one of the keynotes.
Intel also hints at enhanced based overclocking and end user tunability, which sounds promising to many enthusiasts. If all goes well for Intel, Haswell should be quite a nice piece of hardware once it ships in Q2 2013.
