Apple "Since the first rumors of an Apple switch to Intel, everyone has been wondering about the potential speed of Intel-based Macs. Last week's announcement of the first shipping Intel-based Macs brought with it the promise of a major speed boost: Apple's Web pages suggest that the new iMac, powered by the Intel Core Duo processor, is twice as fast as its G5 predecessor. Macworld Lab's tests do show that the new Intel-based iMac is faster than the iMac G5 when running native applications. However, we found that those improvements are generally much less than what Apple claims is a 2x improvement in speed."

[vondur] Steve Jobs Only said in the keynote that the processor was 2x faster in terms of SPEC benchmarks ...

Even that is misleading.

He deliberately used _only_ SPECint_rate2000, not SPECint2000.

See Q15. What is the difference between a "rate" and a "speed" metric?
http://www.spec.org/cpu2000/docs/readme1st.html#Q15

Since the Core Duo is dual-core processor, of course the "throughput" will almost double if the number of tasks are doubled.

By this logic, we shall put Sun's UltraSPARC T1 in a desktop/laptop machine and claim it's 5x - 10x faster?

No surprise in Macworld Lab's benchmark result, since none of them is measuring "througput", which is certainly NOT a key issue on desktops.

It's all about marketing.

What do you expect? Jobs has been spewing misleading marketing BS for years about performance...
