Intel's Core 2 Quad Q8400 CPU Review

Specifactions
Our test system the following details:

Desktop, because we chose to test this very early Core 2 Duo machine, purchased from the platform as Back to the summer of 2006. Apparently, on the desktop can not support the latest Core i7 processor without replacing the motherboard and Ram, but it may help the Q8400 and save all the old hardware. Switching just the processor, we can see exactly what would be the benefits of the system, that is now pushing 3 years old ... Computer of the ancient industry.

2.66GHz clock, the Intel Core 2 Quad Yorkfield 45nm is part of the series. This class processor, 4M bytes of L2 cache and 2MB page. This 1333MHz FSB, a 95W thermal envelope. 1.86GHz total of 2M bytes of L2 cache and a clock, the old E6300, please compare. This 1066MHz front side bus, was low 65W TDP. E6300, technically, in some studies of the actual conditions of different Q8400's TDP is 30W and the poor. On this page, which the new manufacturing process.

Review

The Core 2 Quad Q8400 is a 2.66GHz quad-core processor from Intel, based on the new 45nm process with a 1333MHz FSB and 95W TDP. Although it might not be the last model of Core i7, is a good option if you're just trying to improve the old system processor that supports it. Today let's look at Intel Q8400 and see what kind of performance increase, the exhibition of first-generation Core 2 Duo desktop before, using the 1.86GHz E6300. Read to see what we found.

Power Consumption

I already checked after the upgrade of the processor, the first four-core processor, and its impact on the calculation will be part of a larger force? One core, power consumption may be higher than the same clock speed, this was true, one can only in part. In addition, he claimed time, on - on your browsing activity on the Internet is close to idle, using the original 94-Watt power E6300. wPrime under high load, the use of electricity reached 116 watts. Q8400 is the idle power consumption is 89 watts, DUAL CORE is idle for more than there is a weakness. And 137 watts peak load at a much higher, the lower, which determines the largest part of daily life, they usually do not use the processor. To HTPC, which downloaded from the background of one night, he intends to terminate the low power processors, feature probably much faster.
