Core 2 Duo E7300
Core 2 Duo E7300 processor is hardy a wonder. After our review of Core 2 Duo E7200 a few months ago, the specifications of this new model are in fact quite expected. It uses the same Wolfdale-3M core with L2 cache memory reduced to 3MB and supports slower 1067MHz bus than a full-featured Wolfdale. Compared with the previous model, it has a new multiplier and clock frequency: Core 2 Duo E7300 works at 2.66GHz. The complete specifications of this new CPU look as follows:
Core 2 Duo E7300
Enhanced Intel Speedstep
Intel Virtualization Technology
SIMD instructions support
MMX, SSE, SSE2, SSE3, SSE4.1
Note that compared with a fully-fledged Wolfdale E8000 series processor not only the L2 cache memory and bus speed were lowered. E7000 series CPUs do not support virtualization technology, which, however, is very unlikely to be a problem for mainstream computer users.
CPU-Z diagnostic utility reports the following about Core 2 Duo E7300:
As you can see from the screenshot, Core 2 Duo E7300 is based on M0 processor stepping. It is a cut-down modification of the regular Wolfdale C0 processor revision with a smaller die due to L2 cache half the size of a normal one. As a result, the die in Core 2 Duo E7000 series processors measures 82sq.mm, which is 23% smaller than the die of E8000 series CPUs.
I would also like to add that the new Core 2 Duo E7300 works at the same clock frequency as the youngest CPU in Intel’s high-end dual-core processor family - Core 2 Duo E8200. However, the newcomer will hardly be able to compete successfully against this model, because E8200 features a twice as large L2 cache and 1333MHz bus instead of 1067MHz. However, if we compare E7300 against the top processor from E4000 series, its superiority will be indisputable. Compared with Core 2 Duo E4700, our today’s hero - Core 2 Duo E7300 – offers higher clock speed, larger cache and faster bus, not to mention more advanced and power-efficient core manufactured with 45nm process.
