All the recent hype about the new line of Core 2 Duo Processors definitely caused a lot of excitement among PC enthusiasts worldwide. With the NDA expiring on the 14th of July, Maxit Mag is proud to present a review of the entry level E6300. Dubbed Allendale, this 1.86 GHz Core 2 Duo CPU has 2 MB of L2 cache compared with the 4 MB found in its Conroe siblings.
It seems that the E6300 offers the best bang per buck, hence we decided to use it in our preview. Apart from its lower amount of L2 cache compared to the higher end processors, nothing separates it from the rest of the lineup except its lower clock speed.
Some of the key features of the Core microarchitecture include:
* Dual-core designThe CPU combines two independent cores working in parallel within the same packaging. These cores work at the same clock speed and share 2MB L2 cache. They are connected to the chipset using the same Quad Pumped Bus working at 1066MHz frequency and featuring 8.5GB/s bandwidth.
* Intel Wide Dynamic ExecutionEach of the two processor cores can process four instructions per clock cycle.
* Intel Smart Memory AccessThe enhanced data prefetch mechanism allows to reduce the idling time of the processor execution pipeline.
* Intel Advanced Smart CacheIntellectual L2 cache is shared between the two processor cores depending on their load at the given moment of time. Moreover, the shared L2 cache speeds up data transfer rate between the cores and reduces the front side bus workload, because no data needs to be transferred via the system memory any more.
* Intel Advanced Media BoostThe processor works faster with SSE3 instructions because it can perform the binary operations with 128-bit SSE registers within one clock cycle.
* Intel Virtualization Technology (Intel VT)This virtualization technology allows modeling the work of several virtual platforms on a single hardware system.
* Intel Enhanced Memory 64 Technology (Intel EM64T)The processor supports x86-64 extensions that allow addressing over 4GB of system RAM and support the work with 64-bit general purpose registers.
* Execute Disable BitThe OS is protected against harmful spyware and viruses that use “buffer overflow� error to gain control over the system.
* Lower heat dissipation and power consumptionCore 2 Duo processors are manufactured with the newest 65nm technological process. Thanks to their architecture and a number of power saving technologies they boast the typical heat dissipation of 65W.
