The Intel Celeron T3000 and Intel Core 2 Duo T7250 are dual-core 64-bit mobile processors from semiconductor manufacturer Intel Corp., used for laptop personal computers. The former is an entry in Intel's low-end brand and was released in 2009; the latter, released three years earlier, represents a previous generation of the company's premier brand. Consequently, there are notable differences between the T3000 and T7250.
Manufacture and Socket
Being produced after 2008, the Intel Celeron T3000 uses the 45 nanometer (nm) lithographic node of semiconductor fabrication. On the other hand, the Intel Core 2 Duo T7250 uses the larger 65 nm node, which debuted in the same year. The T3000 is thus a smaller CPU, with its two cores placed on a die that measures 107 square millimeters and contains 410 million processing transistors. The T7250's die measures 143 square millimeters, but has 291 million processing transistors. Each processor uses Socket 478, or Socket N, to connect to the motherboard, although the T7250 is also compatible with the newer Socket 479.
Speeds
Each Intel Celeron T3000 and Intel Core 2 Duo T7250 has a clock speed and front-side bus speed, which refer to its processing rate and data transfer rate, respectively. The T3000 has a clock and FSB speed of 1.8 GHz and 800 MHz, respectively. Although the T7250 has the same FSB speed, it processes faster than the T3000, with a speed of 2 GHz.
Cache and Voltage Range
Each Intel Celeron T3000 and Intel Core 2 Duo T7250 processor has two caches -- a Level 1 cache and Level 2 cache -- which it uses for high-speed access to the computer's most frequently used data. The L2 cache of the T3000 is listed at 1 MB, while that of the T7250 is 2 MB. The T3000 has the wider operating voltage range at 1 to 1.25 volts (V), while that of the T7250 is 1.075 V to 1.175 V.
Technologies
Besides the 64-bit instructional set it shares with the Intel Core 2 Duo T7250, the Intel Celeron T3000 CPU has Execute Disable Bit, which serves as protection against viruses and malicious-code attacks. Intel added to the T7250 Virtualization technology for integrating multiple computing environments into a single PC or server and SpeedStep for high performance while conserving power.
