Overclocking the Athlon 64 X2 4200+

Zitat

When even a bit of multitasking comes into play, however, the 4200+ soars ahead, with significant performance advantages in the general performance PCMark2004 benchmark and an advantage in Multimedia Content Creation 2004. Media Encoding is one particular area where the x2 4200+ shines, outperforming the higher speed 4000+ by 41% at stock speed and by almost 71% when overclocked to 2.7GHz. The performance advantage for Dual-Core in Media Encoding is so significant that the X2 becomes a "must-have" if you do much media encoding.

These results are all while running in Windows XP, and there should be even further performance improvement in the 64-bit version of XP. Until there are useful benchmarks that really take advantage of the 64-bit OS we can only speculate on 64-bit performance, but the clean implementation of 64-bit by AMD should definitely yield performance advantages in 64-bit. The advantages should be similar to those AnandTech found for Opteron in the recent article comparing processors in 64-bit Linux.

The point of this article though is OVERCLOCKING the 4200+, and there is more good news there. Our early 4000+ processors only overclocked about 11 to 12% at stock multiplier. We do have a later 4000+ (that is likely an FX55 at heart) that overclocks about 18% at stock multiplier, which is the one we use in memory reviews. This 4200+, a new speed grade, is doing 22.5% at the start, reaching 2.7GHz on air. That's a 500MHz overclock, and is 300MHz higher than the fastest x2 you can buy (2.4GHz 4800+ and 4600+). This kind of overclocking performance makes the 4200+ a much more attractive option at the $500 you will pay for it - since it will likely reach higher performance levels that a stock 4800+.

[...]The 4200+ running OC at 2.4GHz is equivalent to a 4600+, which brings us back to the question of which x2 Athlon 64 we would buy for ourselves. With the 4400+ sporting 1MB cache on each core, and only a few dollars more than the 512KB 4200+, we would suspect the 4400+ may well be the Dual-Core to buy - IF it overclocks as well as the 4200+. We don't have a 4400+ to test for ourselves, but given the performance of the 1MB cache 4800+ we have seen, we expect the 4400+ will likely overclock just as well.

afair schaft der pentium xe da noch immer a quäntchen mehr (natürlich @ stock )
