The codename Napa designates the third-generation Centrino platform, introduced in January 2006 at the Winter Consumer Electronics Show. The platform initially supported Intel Core Duo processors but the newer Core 2 Duo processors were launched and supported in this platform from July 27, 2006 onwards. Centrino. The Test Platform. For today's review we compared Intel's Core 2 Duo T7600 (2.33GHz/4MB) to Intel's Core Duo T2600 (2.33GHz/2MB). The apples-to-apples comparison starts with two CPUs with The Intel Core Duo's inclusion of two highly efficient cores on one chip can provide better performance than a Mobile Pentium 4 core, and with much better power-efficiency. On July 27, 2006, Intel's Core 2 processors were released, which offered x86-64 compatibility and eventually displaced Yonah in production. See also. Intel Core; Merom; Centrino Benchmark results for the Intel Core 2 Duo L9400 can be found below. The data on this chart is gathered from user-submitted Geekbench 6 results from the Geekbench Browser. Geekbench 6 scores are calibrated against a baseline score of 2500 (which is the score of an Intel Core i7-12700). Higher scores are better, with double the score indicating The biggest feature of the Thinkpad T60 is the fact that it is one of Lenovo’s first Centrino Duo capable notebooks. The sample we got was in fact a Centrino Duo system as it was equipped with Intel Core Duo T2500 : 2.00GHz: $492: Intel Core Duo T2400: 1.83GHz: $363: The numbers don't lie -- Core Duo is fast and efficient, and the Centrino Duo stuff is going to make Intel a pile of Yes, all Core 2 Duo chips are 64-bit capable, that is includes the EM64T feature. Of course, if your running a 32-bit OS then it'll be no different then a 32-bit chip, but if you put a 64-bit OS on your system the Core 2 Duo chips will handle it properly. So yes it is capable of running 64-bit Windows. Intel® EM64T requires a computer system Price and performance details for the Intel Core2 Duo U7300 @ 1.30GHz can be found below. This is made using thousands of PerformanceTest benchmark results and is updated daily. The first graph shows the relative performance of the CPU compared to the 10 other common (single) CPUs in terms of PassMark CPU Mark. At the heart of the platform is the 45nm Core 2 Duo processor series, all based on the x86 design previously known as Penryn. It's been beefed up with a 1,066MHz memory or frontside bus (FSB) and The Intel Core 2 Duo P8700 is a mid-range dual core processor for laptops. It features 2.53 GHz and a shared level 2 cache of 3 MB. Due to the smaller cache (Core 2 Duo T-Models got usually 6 MB yCaf0i6.
