Intel's New Core 2 Duo Processors Run Blazingly Fast in PC World Tests
Exclusive PC World tests show that PCs equipped with Intel's new Core 2 Duo processors, formerly code-named Conroe, set new high marks for desktop performance--they're the fastest we've seen by far.
With this chip line, due to launch formally on July 27, Intel decisively reclaims the power desktop crown from competitor AMD.
In our WorldBench 5 test suite, Intel's Core 2 Duo reference system outscored a matching system equipped with AMD's high-end Athlon 64 FX-62 chip by 17 percent. We also tested shipping PCs based on several chips in the Core 2 Duo family, including a water-cooled, overclocked ABS machine that posted a mark of 181 on our WorldBench 5 test--the highest WorldBench score we've ever seen. (See our detailed test results. For full reviews of four new Core 2 Duo-based systems, click the product names in the results chart.)
All of our Core 2 Duo configurations performed impressively, and the higher-end models in particular should allow power users to handle demanding multimedia work on their PCs more quickly and to perform multiple computing tasks at once more efficiently. Gaming, too, will receive an impressive boost from systems equipped with the new chips.
Though its new products are good news for users, things are different for some Intel employees, as the company announced the layoff of 1000 management employees today.
The Core 2 Duo Line
The Core 2 Duo processor line ranges from the 1.86-GHz E6300 chip ($183) with 2MB of cache to the 2.93-GHz Core 2 Extreme X6800 chip ($999) with 4MB of cache; all have a 1066-MHz system bus. (Intel leaves the "Duo" designation off of its X6800 CPU.)
Though Core 2 Duo chips use the same Socket 775 interface as current Pentium 4 and Pentium D chips, they require new chip sets, so you'll have to get a new motherboard--you can't just pop a Core 2 Duo chip into your existing Intel-based PC and reap the tremendous performance gains. The Core 2 Duo reference systems we tested used a motherboard with Intel's 975X Express chip set (boards using the P965 Express chip set will also be available); nVidia and ATI have their own Core 2 Duo boards as well.
The new processors and systems will be on sale from various vendors beginning July 27, with some configurations of Core 2 Duo machines checking in at surprisingly reasonable prices.
Our motherboard Core 2 Duo test setup consisted of an Intel 975X Express board, 2GB of DDR2-667 memory, a pair of SATA hard drives configured in a striped array, and an nVidia GeForce 7800GT-based graphics card. We swapped first a 2.93-GHz Core 2 Extreme X6800 chip and then a 2.67-GHz Core 2 E6700 chip into that setup to generate scores we could compare directly to an otherwise identically configured system featuring AMD's new DDR2-capable AM2 platform and its top-of-the-line FX-62 processor.
Both of the Intel setups bested the AMD-based system on every test in our WorldBench 5 suite as well as on every one of our gaming tests (see chart below). The improvement on WorldBench 5's multitasking tests, which involve running a Web browsing session in Mozilla while encoding a file with Windows Media Encoder, was particularly dramatic. You'll also see notable gains in Photoshop and similar graphics applications.
Footnotes: 1Tests run at 1024 by 768, 32-bit color without anti-aliasing. fps = frames per second. 2This system was liquid-cooled and overclocked to 3.5-GHz. 3This system ran Windows XP Media Center Edition. 4This system had 1GB of RAM. 5This system ran Windows XP Home. Tests conducted by PC World Test Center. For details on how we test, go to our WorldBench 5.0 page. All rights reserved.
Chart notes: Reference PCs were configured with 2GB of DDR2-667 memory, a pair of SATA hard drives in a striped array, and an nVidia GeForce 7800GT-based graphics card. All systems ran Windows XP Profesional and had 2GB of RAM unless otherwise noted. Higher is better for WorldBench 5 and the gaming tests. Elsewhere, lower is better. Bold denotes best score. Italicized systems are non-Core 2 machines for testing comparison.
