As previously reported, the Core i5 750 part features clock speeds in the range of 2.66 and 3.2GHz using Turbo Boost and no Hyper-Threading. Meanwhile, the higher-end Core i7 870 will run at 2.93GHz with a top speed of 3.46GHz for individual cores and supports Hyper-Threading technology for up to eight threads. So how did they fare in the tests? A brief look shows that despite being limited to dual-channel memory and the old DMI interconnect instead of QPI, the Core i7 870 outperforms the existing Core i7 920 overall.
A screenshot of CPU-Z also shows the effect of the Turbo Boost feature which increases the frequency of the Core i7 870 to 3.2GHz. The Core i5 750 appears to be the most power-efficient of the bunch but still manages to sit between the Core i7 920 and Core 2 Quad Q9550 in terms of performance. Both chips will outclass AMD’s Phenom II X4 955, according to PConline.
Naturally, you should take these results with a grain of salt considering Intel hasn't even announced the CPUs yet, but it’s always interesting to see some numbers. The report includes benchmark results from applications such as WinRAR, Everest Ultimate and CineBench to games like Call of Duty: World at War and Far Cry 2. You can find a translated and somewhat readable version here – the graphs are pretty self-explanatory, though.
