Intel Core i5 750, Core i7 870 Linux Benchmarks

Filed under
Hardware

Now that we have provided a brief overview of the Intel P55 and how it functions under Linux, our larger area of concentration is looking at the Linux performance of the P55 with the new Core i5 750 and Core i7 870 processors. We have a number of benchmarks in this article along with more information on these Lynnfield processors.

The key features that Intel highlights for its new Core i5 processor family is quad-core processing, Intel Turbo Boost Technology, 8MB Intel Smart Cache, Integrated (DDR3) Memory Controller, and Intel HD Boost. The inaugural Core i5 processor is the 750 model that is clocked at 2.66GHz, has 8MB of smart cache, up to 3.20GHz for its Turbo Boost frequency, four threads (the Core i5 lacks Hyper Threading), and an integrated dual channel DDR3-1333MHz memory controller. The Core i7 800 series processors share many features with the Core i7 900 series that have been out on the market for a while with X58 motherboards, except for lower clock frequencies, a dual channel DDR3 memory controller instead of a triple channel controller, and a LGA-1156 socket versus LGA-1366. Lynnfield also uses DMI (Direct Media Interface) rather than QPI (QuickPath Interconnect) as found on the Core i7 900 series.

Intel Core i5-750 and Core i7-870

reghardware.co.uk: We published an in-depth look at Intel's 45nm 'Lynnfield' processors - aka the quad-core Core i7-870 and Core i5-750 - last week. Unfortunately, the chip giant's non-disclosure agreement (NDA) prevented us from including full performance figures.

Intel officially launched the new chips yesterday morning, so we're now free to present the results of our benchmark tests in full.

Overclocking Intel's Core i5-750 & i7-870

techgage.com: We found out earlier this week that Intel's Lynnfield-based processors are fast, but who said that cranking the clocks to make them even faster was a bad idea? In this article, we take both the Core i5-750 and i7-870 for an overclocking joyride, and the stable overclocks we were able to achieve is nothing short of impressive.
