Led The Fourth Quarter Of Nehalem Cpu Debut New Scan
For the processor market, the fourth quarter of 2008
, not ordinary. Big Brother as a processor, Intel will be in mid-November to achieve its two-year commitment for a change, launched a new generation Nehalem architecture processors Corei7. After following the Core architecture for another masterpiece, Intel Nehalem made in great improvements put a lot of resources. With the Core architecture Core 2 different, Nehalem is Intel The first use of QuickPath interconnect system architecture of the processor. Nehalem Core microarchitecture is substantially modified from, plus the addition of SMT, 3 layers Cache, TLB and branch prediction of the hierarchical, IMC, QPI, and support for DDR3 and other technologies, but as with the Core architecture, Nehalem is 4 the width of the decoding instruction / rename / remove.
Major media release of evaluating the current data view, Nehalem processor architecture Corei7 satisfactory performance, especially in Memory Performance, since the integrated DDR3 Memory Controller, so that Corei7 greatly enhanced memory performance. But in the three-channel performance, a bit flawed, though improved compared with dual-channel, but the rate is not significant. In addition, with the return of Hyper-Threading Technology, an increase of 3 cache design, the new bus is equipped with PQI and SSE4.2 instruction set to join, so Corei7's performance to an entirely new level. The strongest known in the history of the desktop Nehalem platform that is no exaggeration, because A MD Side did not produce any comparable with the Core i7 products, they are still struggling with K10 architecture.
As TLBBUG and technology and many other reasons to know, AMD's K10 architecture processor in addition to bouncing again and again outside the mediocre performance of so many players down. K10 from the release date, AMD has been struggling in fact. Although the advantages of AMD with a cost-effective (main for the Old Boys of K8 dual-core and multicore processors, the lowest of K10), in market share also increased, but customers are the most sensitive performance, AMD is unable to come up with a products to compete with Intel 45nmPenryn.
AMD will want to send in the 45nm's "Deneb" and for Server Market, "Shanghai" processor. As the AMD Phenom processor quad-core processors with Intel Core processors in the competition at a disadvantage, so early before the Phenom release, AMD has announced the launch of K10.5 processor in the fourth quarter, which is known as the " Shanghai "processor. K10.5 "Shanghai" will be an enhanced K10 processors using 45nm process technology, which has a 512KB L2 cache per core, and has 6MB of level three cache memory and support RDDR2 3xHT3, support for AMD-V technology. And for the desktop market, "Deneb" (ie PhenomFX) will be available in 2009 (with a message saying that he would launch in the fourth quarter ahead of schedule), allegedly, AMD and 2.8G of DENDB sure 3.0GHZ processor enough to deal with Corei7 920 2.66GHZ, but the price is between 300-400 U.S. dollars, higher than the Core i7920.
No matter how, in the fourth quarter, Intel and AMD the performance of a new round of struggle has been launched. Now, Intel accounts for an absolute advantage, while AMD is waiting for the opportunity counterattack. Here we take a look, in the fourth quarter, which CPU Cutting-edge is worth our attention!
