New Details on Intel's Dual-Core Mobile Chip
The processor's two cores will share a single bank of cache memory.

Intel shed a little more light on its forthcoming dual-core mobile chip today in a briefing with reporters, confirming that the Yonah processor's two cores will share a single bank of cache memory
Yonah is the code name for the dual-core version of Intel's Pentium M processor for notebooks and miniature desktops, scheduled for release in the first quarter of next year. Unlike Intel's first dual-core designs for desktop PCs, Yonah is a much more integrated design that shares storage and power management resources within the chip, said Mooly Eden, vice president and general manager of Intel's mobile platforms group.
The just-released dual-core Pentium D processor uses separate 1M-byte cache memory banks dedicated to each core. In the Yonah processor, a single 2M-byte cache memory bank is available to both cores, reducing the chance that data will have to leave the chip to be temporarily stored in a system's main memory bank, Eden said.
What's the Cache?
Cache memory is used to store frequently accessed bits of data in a repository close to the CPU (central processing unit). Data stored in cache memory can be accessed much faster than data stored in a PC's memory, because the CPU doesn't have to exit the processor to find that data.
As a result, the battery life of notebooks with the Yonah and the rest of the Napa platform should exceed that of the current generation of Intel's Centrino technology, Eden said. Napa is the code name for the combination of Yonah, a new mobile chipset, and a new wireless chip that makes up the Centrino brand.
Intel plans to aggressively introduce dual-core processors over the next year. The company was forced to accelerate its dual-core processors after realizing that it could no longer wring any more performance out of single-core Pentium 4 chips without melting motherboards. Processor analysts and chip enthusiasts have turned their noses up at Intel's initial Pentium D design, labeling it inelegant compared to AMD's dual-core chips.
The difference between the dual-core Pentium D processor and Yonah is also quite stark, Eden said in response to a reporter's question.
"You are asking me what is the difference between a microprocessor and a donkey," he said. 驴就驴啦，干吗还要是蠢驴！ 支持一下楼主 AMD公司的全球营销高级副总裁Henri Richard昨天在台北电脑展(Computex)上表示，Intel的双核平台由两个置于不同晶片内的处理核心所组成，只是使用了多片包装技术将它们封装在一起，严格说来，这种产品并不是真正意义上的双核解决方案。
虽然Intel首先发布了用于台式机电脑的双核处理器解决方案，但Henri Richard称真正的双核处理器应该是把两个处理核心(core)整合在同一个硅晶片(die)之上。
Intel的移动平台分部总经理Anand Chandrasekher曾表示Intel很有信心在今年第三季时出货10万颗双核处理器，预计全年出货量更可突破100万颗。
对于有市场传闻称AMD计划开始生产芯片组，Henri Richard表示AMD是不会进入这一市场领域的，因为他们和各大芯片组厂商关系良好。此外，他还批评了Intel将各种产品（CPU、芯片组和无线模块）捆绑在一起的所谓平台战略。 呵呵，AMD 也一样，前段时间不还爆了内幕，有个副总裁把大陆的大单都搞砸了吗？
大家当笑话看好了。 其实Prescott是被下了套的，别看执行流水线长，执行流水线本身反倒是可圈可点，常用和重要的计算指令延迟并没有变长，有的还缩短了，HT吞吐量也改善了。
不知道是Intel实力过强还是看穿了A64的性能上界要么内部有人故意要废掉Prescott，在缓存延迟上倒是拖后腿的真正原因。PM和ia64上可以看出，Intel完全具备制造低延迟大容量cache的技术能力，但是Prescott根本不需要，什么原因？还是A64不够强或者目前并不需要让这个武器具备毁灭性而阻挡了PM派别(给Intel带来了巨大利润)抬头的势头。
意思的是：缓存延迟才是Prescott的主要问题，并不是什么流水线太长。 断章取义～～～ 现在是K8的天下。 The company was forced to accelerate its dual-core processors after realizing that it could no longer wring any more performance out of single-core Pentium 4 chips without melting motherboards. 呵呵，楼主的D代表什么意识？
