AMD Better At 64-bit Than Conroe?

By now, we've all seen how Conroe performs. However, all the Conroe reviews circulating around the 'net have been centered around 32-bit applications where the Conroe is clearly king. Some people have taken note of this and many concerns about Conroe's 64-bit performance have been raised. The guys over at X-bit take a look at how the Conroe matches up to AMD in the 64-bit arena in an attempt to find some answers.

"At the same time I would like to point out that it looks like Athlon 64 processors ensure higher performance increase when switching to 64-bit work mode. The average performance improvement we have seen from Athlon 64 FX-62 equaled 16%, while Core 2 Extreme X6800 demonstrated only 10% average performance boost. This way, there is a certain difference: AMD K8 turns out 6% mode efficient in 64-bit mode than Intel Core. However, this difference cannot compensate for the 20% performance advantage of the Intel Core 2 Duo over the Athlon 64 X2 working at the same clock speed, which we have pointed out in our previous articles. Therefore, we will not change our conclusions about the performance of the new Intel processors even keeping in mind the upcoming launch of 64-bit Windows Vista OS family."
