Intel Core 2 Duo E8400 3.0GHz 1333MHz FSB Processor Review

Intel Core 2 Duo E8400 3.0GHz 1333MHz FSB Processor Review - PCSTATS
Abstract: Intel's Core 2 Duo E8400 is a 3.0GHz dual-core processor based on the 'Wolfdale' core that is being manufactured on the 45nm process. This socket 775 processor packs in 6MB of L2 cache and operates with a 1333MHz Front Side Bus speed.

Core 2 Duo E8400 Workhorse CPU

In this age of quad-core processors, can a dual-core processor really cut it? CPU manufacturers AMD and Intel have repeatedly emphasized that multi-threaded applications are the future of computing, and that both companies will soon relegate single and dual-core processors to entry-level markets. As quad-core processors become more widely adopted in the mid-range and high-end, we're going to see more developers taking advantage of them with multi-threaded software. There are already a few bleeding-edge applications like Bibble that do this.

Right now, however, these applications are few and far between. Most of the utilities, office applications and day-to-day software that's on the average computer won't know what to do with extra CPU cores and will be served by a processor with more cache or higher clock speeds.

Keeping this in mind, the spotlight is clearly on Intel's family of Core 2 Dup E8000-series Wolfdale processors. The Core 2 Duo E8400, with its 3.0GHz clock speed, 1333MHz FSB speed and 6MB of L2 cache, remains a force to be reckoned with. In tests like Sysmark that test common, real-world office applications, the E8400 was generally a little faster than the Phenom II X4 955 and a little slower than the Core i7 920. All processors are absolutely fast enough for average desktop applications likely to be encountered in the office or at home. The same holds true during gaming, where the majority of titles are more suited to high-frequency dual-core processors rather than parallel quad-core processors.

With a current street price of $199 CDN ($170 USD, £113 GBP) the Intel Core 2 Duo E8400 is $100 cheaper than the AMD Phenom II X4 955 and $150 than the least expensive Intel Core i7 processor. While the quad-core processors can definitely outclass the Core 2 Duo E8400 in certain scientific simulations, 3D rendering and video encoding benchmarks, they just don't deliver as much everyday value as a speedy dual-core processor.

Under the hood, the Intel Core 2 Duo E8400 isn't revolutionary. While the original Conroe E6000-series processors were manufactured on a 65nm process, the Wolfdale chips are produced at 45nm. Shrinking the chip has kept the E8400's power draw levels low, just 65W, so under full CPU load it actually draws less power than lower-performing processors. Intel has also added new SSE extensions, lower power states, and better hardware virtualization support.

Overclocking the Intel Core 2 Duo E8400 was dead simple, with only a minor bump in voltages required to move the processor from 3.0GHz up to 4.05GHz when using the stock Intel cooler. While we didn't do any official benchmarks at that speed, a 4GHz E8400 is enough to give the Core i7 920 a run for its money in many single and dual-core applications.

Given the benchmark results I think it's safe to say two things are clear. The Intel Core 2 Duo E8400 processor is handicapped against triple and quad-core processors in tests that are multi-threaded. In standard desktop applications that people use everyday, like Word or email, surfing the web or doing spreadsheets, the Core 2 Duo E8400 is more than powerful, and a very good value. While those that specialize in content creation may have already embraced quad-core processing, most everybody else will find that a speedy dual-core CPU like the Core 2 Duo E8400 is a better value.
