Q8400 OC ability is quite good. The FSB can reach 501MHz.

In most multi-core software, Q8400 all gets very high score.

Windows7 full mark is 7.9 and Q8400 gets 7.5.

E6300/Q8400 are different with pervious products. They all support VT-x technology. It will make Windows7 performance be better.

These 2 CPU launched price is only a little bit higher than old products. I think it’s good product transition plan.

Hope Intel will keep providing LGA775 CPU.

Core 2 Duo is Intel long life cycle product. The hi-end segment is i7.

If considering CPU/MB models and price, Core 2 Duo/Core 2 Quad are good choice.

As i5 is still unclear, Core 2 Duo platform still your best shoice.

Windows7 Processor 7.2

Hyper PI can run quad cores to test stability and performance, but doesn’t support multi-core structure.

The actual performance is still little bit slower than single core. The CPUMARK99 is only for single core performance.

Other software all support quad cores, so the performance is much better.

As multi-core software, Q8400 default 2.66Ghz X 4 is still higher than E6300 OC to 4.2Ghz X 2.

Windows7 Processor 7.0

After OC, E6300 performance is improved in all benchmark software.

If need to reach 4G, you need about 1.376V. It’s better than E5200/5300 R0 stepping.

But the voltage is still higher than E5200 M0. Look forward E6300 having better OC to replace E5 series faster.

When OC to 4.2G, Windows7 score E6300 at 7.0

Second one is Intel Core 2 Quad 8400

FSB 333Mhz?Clock 2.66Ghz?L2 cache is 4MB?power consumption 95W?

It’s Intel entry quad core product, the price is 6000NTD, around 180USD.

This model also has energy saving version, 65W?Q8400s?but Q8400s is higher than Q8400 around 30USD.

Intel Core 2 Quad 8400 CPU and bundled Cooler

As Q8400 is quad core CPU, the thinner Cooler bottom is copper.

Core 2 Duo CPU got very good reputation as announcing and Intel launched Core 2 Quad CPU later to pull up the multi-tasking performance.

Last year, Intel announced Core i7, has higher performance, for hi-end market. And you will see i5 CPU soon.

For the Intel 3 socket structures, LGA775 is the oldest one and for mainstream market. However, the C/P value is still high.

Core 2 Duo product line can be divided by frequency and L2 cache.

Most hi-end is E8 series, 333 FSB and L2 6MB, then is E7 series, L2 is 3MB, belongs to mid-hi market.

The cheaper one is E5 series, 200 FSB and 2MB cache. Power consumption is 65W, Code name is Pentium.

Pentium is quite confusing user it’s Pentium4 structure.

It’s not so, E5 series is Core 2 Duo, just only cache different.

Of course, we cannot forget the most entry E1 series with 512K cache. The code name is Celeron. As it is Core 2 Duo structure, the performance is still good.

This time I buy is Intel Pentium Dual-Core E6300

E6300, very familiar ID, is Intel 65nm mid-hi product, and in fact it’s Pentium Dual-Core E6300 to replace E5 series.

L2 is 2MB and the FSB is 266MHz, the clock is 2.8GHz.

The current price is 2650NTD, around 80USD.

Intel Pentium Dual-Core E6300 CPU and bundled Cooler

Intel CPU all use thinner cooler after 45nm manufacturing process.

CPU is R0 stepping. In the forum, as E5200/E5300 transfered to R0, the OC ability is worse.

I hope E6300 can have better performance in R0 stepping.

This time I use MB-GIGABYTE GA-EP45T UD3R

DDR3 price has been dropping for several months. As the current market price, DDR3 platform becomes much cheaper.

SB heatsink shows it supports DDR3.

6 phase PWM, 2oz copper PCB and all Japanese solid capacitors.
