New choice of the summer anthology five IVB new notebook recommended

Again to the annual summer vacation, the major notebook manufacturers also ushered in a new round of the climax. The notebook market, which has been quiet for several months, has finally started to boom with Acer, Sony and Asus, who have introduced their newest mold. For students and friends, also to buy a notebook of a peak, today's small series for you recommend a few new notebook, they almost all equipped with the latest Intel platform IVB processor. Before introducing, first please understand some basic performance of new platform IVB.

The evolution of SNB to IVB has not changed so earth-shattering in the core architecture, but it has made the world crazy just by upgrading from 32nm to 22nm technology. New Ivy Bridge architecture under 22nm technology the core processor not only achieves performance improvement, but also has a significant breakthrough in reducing power and heat.

As mentioned earlier, the 22 nm process technology and the three-grid-level transistor technology is the most notable feature of the IVB architecture, which not only supports ddr3-1600 memory controller, but also improves the i/a core and ISA instruction set architecture, and optimizes Isa for SSE extended instruction set and string processing. In addition, the IVB architecture has been enhanced and upgraded in security and energy management, adding configurable TDP technology and supporting higher-frequency memory and low voltage memory.

As with the processor, the upgrade of the graphics card is also very obvious, the new generation HD Graphics 4000 core graphics card also uses 22 nanometer process technology, improved the original 3D micro-architecture while reducing power consumption. The biggest change is in support of Microsoft DirectX 11, which can go beyond the current entry level alone.

In addition, two other major improvements to the new IVB architecture are the addition of USB 3.0 controllers and increased support for PCI-E 3.0, the first time that PCI-E 3.0 has been used for mobile platforms since the SNB era, reducing memory and chipset transitions, resulting in lower latency and shorter response times. Performance is also improved.

The above content is somewhat vague, so what is the performance of the new IVB processor? By testing the results, we can use a simple sentence to summarize: 22nm process of Ivy Bridge architecture processor, its computing power to achieve the I3=I5 (old), i5=i7 (old) completely beyond.

The performance of the cup is almost doubled, and the GPU improvements are obvious, with the mobile platform GT2 containing 16 or 24 EU, which is what we now call the HD Graphics 4000 core graphics card. The Ivy bridge GPU has increased the coding speed of quick sync to twice times that of Sandy Bridge, and the image quality has been improved a little.

The 3DMARK 06 test allows you to see that the graphics score of Intel HD Graphics 4000 is basically equal to gt520m and gf610m. Compared to the previous generation of HD3000 core graphics, the increase is about 38%, which shows that the new HD Graphics 4000 core Graphics performance has been successful beyond the entry level, and is likely to reach the level of the midrange video card.
