Intel is finally bringing dual-core technology to the Celeron family. At first this could sound contradictory since the goal of Celeron processors is to be a low-cost CPU targeted to those users that can’t or don’t want to pay for a CPU with the latest technological features available. However dual-core technology can’t be considered “the latest technological feature” anymore and historically what Intel does is to push what was once a high-end feature to the mainstream CPUs and then, after a while, to the entry-level CPUs. Since today’s high-end CPUs are quad-core and Intel has been selling only dual-core CPUs for the mainstream market for quite a while, not more natural than start introducing dual-core CPUs to the entry-level market as well. As you can see on a near future we will only have CPUs with at least two cores available on the market.

Dual-core Celeron processors are based on Core microarchitecture, the same used by Core 2 Duo CPUs. These CPUs are also known by the codename Allendale.

Celeron E1000 series main features are:

• Core microarchitecture
• Dual-core technology
• Manufacturing process: 65 nm
• L1 cache: 64 KB total, 32 KB for instructions and 32 KB for data.
• L2 cache: 512 KB, shared by the two cores
• External clock rate: 800 MHz (200 MHz transferring four data per clock cycle)
• Packaging: FC-LGA6
• Socket: Socket 775.
• SSE, SSE2 and SSE3 instructions
• Execute Disable technology
• EM64T technology (a.k.a. 64-bit technology)
• Enhanced SpeedStep technology

Available models of Celeron E1000 series are listed on the chart below. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation.
