As observed earlier this week, Intel’s embargo on the LGA-1156 platform isn’t worth much to some, especially East of here where both motherboards and processors are being sold way ahead of the official launch. This has resulted int he first extensive tests of Intel’s new processors and at INPAI.com.cn they published a full review review of Core i5-750 that reveals impressive performance and power usage.
The benchmarks compare Intel’s new mid-range CPU, Core i5-750, to the first generation Nehalem architecture. Fittingly they have used the entry model of the Core i7 family, i7-920, which operates at the same frequency as Core i5-750.
The differences between the two are that Core i7-920 supports HyperThreading for a total of eight simultaneous threads, something Core i5-750 lacks, while the Core i7 models also has a triple-channel DDR3 memory controller, while the i5 series is limited to two channels.
The sum of if all is that Core i7-920 is really only faster in extremely multithreaded applications. The extra memory channel, has little to no effect on real performance. In games and single-threaded environments the performance is more or less identical.
At the same time Core i5-750 offers more bang for the buck, not just a cheaper platform price but also thanks to lower power consumption. The processor is rated TDP 95W while the more expensive Core i7-920 comes with 125W TDP, while Intel’s P55 chipset looks to be a bit more efficient than the X58 equivalent of the LGA-1366 platform.
More tests and reviewers of Intel’s new Lynnfield family will most likely appear in the coming weeks up until the launch in September.
