A few tasty Banias nuggets
X-bit labs has some more details on Intel's mysterious Banias processor for mobile computers. According to X-bit, Banias will feature a whopping 1MB of L2 cache on a die that's only 75% of the area of Northwood Pentium 4 processors. More cache on a smaller die means that Banias' processor core is really, really small.
Perhaps the most interesting claim made about Banias is that it will have a higher IPC than the Pentium 4:
It is very important that architecture efficiency of Banias processor is so high that 1.6GHz model will offer the same performance as Pentium 4-M 2.2 or even 2.4GHz does! Considering that according to the current estimates, Banias based performance notebooks will be able to work 50% more time compared to current models based on Pentium 4-M without recharging the battery, this CPU will be one of the best performance/power consuming solutions around.
If the claims are true, and Banias is much faster clock-for-clock than Pentium 4 processors, I have to wonder if Intel will introduce a PR rating scheme of its own. We'll just have to wait and see.
