Intel has recently introduced the P35 chipset with a fast 1333MHz FSB and DDR3 memory support – and we have found that the P35 chipset is quite an excellent performer, and when tied to speed DDR3 memory modules, it can provide high performance – albeit currently at a painfully high price. 

Today, we look at one of Intel's 1333MHz FSB processors – the E6750 – which runs at 2.66GHz (333MHz x 8), and is the same as an E6700 which also runs at 2.66GHz (266MHz x 10) but with the lower 1066MHz FSB rate. 

Intel was kind enough to send us an engineering sample, and we put it through its paces. 

In our previous Core 2 Duo reviews (E4300, QX6700, E6600, E6300/E6400, E6700)it was very apparent that the 1066MHz (266MHz x 4) FSB was limiting the performance of the processors as it was limiting the memory and I/O bandwidth of the processor to less than 8.5GB/sec throughput. So with the new 1333MHz (333MHz x 4) FSB raising the potential bandwidth to 10.66GB/sec we expect to see the same kind of performance gain we observed earlier when we overclocked the FSB on past 1066MHz FSB chipsets and processors – the 25% increase in bandwidth was quite noticeable. 

As our past DDR3 reviews/comparisons have shown us that at this time high speed DDR2 still performs better than DDR3-1333MHz modules. We decided to go with our old favorite, the Corsair XMS2-TWIN2X2048 PC-8888 (4-4-4-12/2T) and the OCZ PC2-9200 (4-4-4-12/2T) modules in order to make certian we got the best possible memory performance for the processor.
