Abbyy FineReader
We mentioned it earlier, Abbyy is optimized for parallel processing on Intel CPUs but does not correctly recognize / take advantage of AMD multicore processors. As a result, the AMD CPUs only run at roughly 50% load. For these reasons, we only show a comparison between the currently available Intel multi-core CPUs.
Final Thoughts
Intel's latest processor release is another evolutionary step in the development of the Pentium4. With its 65 nm interconnect processs and 35 nm transistor gate length, the P1264 process sets new standards but overall it appears that while it is a giant leap for Intel, it is still a small step for overall desktop performance. Likewise, the powerconsumption of the Presler die certainly does not fall into the category of environmentally friendly. This does not mean that the Presler is a bad processor, on the contrary, it does have a huge amount of horsepower which is evident in those applications that can take advantage of it.
On the other hand, it appears as if there is finally an end to where the Netburst architecture can be pushed, and that end is dictated primarily by the processor interface with the rest of the system. The Intel host bus interface is no longer capable of putting up with the requirements of the CPU, not so much in terms of bandwidth as needed in streaming applications but rather in terms of overall latencies of the bus, specifically since it is bidirectional and shared between cores. What this means is that when one CPU reads, the other one cannot write to the system and vice versa. If there were any way of implementing a dual ported interface, the performance might take a quantum leap, as it stands, it appears as if no matter how powerful the CPUs will be (if there are any further releases), the performance will still stagger.
