Intel Core i5-750 Processor

When it launched last year, the Core i7 platform redefined Intel's high-end processor segment. Unfortunately, the platform was also accompanied by high-end prices. As such, it has seen only a minimal share of the desktop market. Today, however, Intel is releasing a new platform that it claims will bring the performance of Nehalem to mainstream price points. Referred to as Lynnfield, the new platform shares its core microarchitecture with the i7-900 series, but introduces a completely new chipset and socket design. This means that not only will we see new processors, but new motherboards as well. Benchmark Reviews has been testing several of these new items and will be covering the launch in detail over the next few days. In this article, we examine the Intel Core i5-750 Quad Core Processor model BX80605I5750.

The Intel Core i5-750 is one of three processors launching today under the Lynnfield platform, the others being the Core i7-860 and Core i7-870. All three chips are based on the same die, feature 8 MB of share cache, and are packaged using the new LGA 1156 socket. They also feature a new version of Intel's Turbo Boost Technology that dynamically overclocks the individual processor cores depending on workload. As the naming scheme suggests, however, the Core i5-750 is the low end part out of the three. This is in part due to clock speed, as the i5-750 runs at only 2.66 GHz compared to 2.80 GHz for the i7-860 and 2.93 GHz for the i7-870. The key difference, though, is the lack of Hyper-Threading. According to Intel, all of the Core i5-700 series processors will be limited to one thread per core, while the Core i7-800 series, will be capable of two threads per core. We'll see how much of an impact this has on performance when we get to the benchmarks a little later on.


The Core i5-750 may be the underdog of the Lynnfield launch, but with a launch-MSRP of $199 for the BX80605I5750 kit, it's certainly not a budget processor. The good news is that the new P55 chipset from Intel should offer a considerable price break compared to the X58. Intel moved the bulk of the Northbridge functions to the processor and combined the rest with the Southbridge to deliver a single chip solution called Ibex Peak. The memory configuration has also been reduced, from triple-channel to only dual-channel support. We'll cover this in more detail in the P55 motherboard reviews. However, let it suffice to say that the new chipset should bring system prices down quite a bit. Whether or not they'll be the mainstream prices Intel claims remains to be seen.

About Intel Corporation


Intel Corporation is the world's largest semiconductor company founded by semiconductor pioneers Robert Noyce and Gordon Moore, and widely associated with the executive leadership and vision of Andrew Grove, Intel combines advanced chip design capability with a leading-edge manufacturing capability. Originally known primarily to engineers and technologists, Intel's successful "Intel Inside" advertising campaign of the 1990s made it and its Pentium processor household names.

Intel pushes the boundaries of innovation so our work can make people's lives more exciting, fulfilling, and manageable. And our work never stops. We never stop looking for the next leap ahead-in technology, education, culture, manufacturing, and social responsibility. And we never stop striving to deliver solutions with greater benefits for everyone. Intel is making PCs more accessible and affordable through innovative PC purchase programs. Through public and private collaboration, Intel has worked closely with government and industry leaders to develop more than 200 programs in 60 countries. With the onslaught of wireless broadband communication technologies like WiMAX, Wi-Fi, and 3G and wireline ADSL and cable, Intel in collaboration with local governments is connecting more people in more places than ever before-no matter how remote.

Intel is committed to improving education on a global scale. With an ongoing focus on students and teachers, we're making an impact with technology solutions that support the development of 21st Century skills, including digital literacy, problem solving, and critical thinking. As citizens use the Internet, the need to create localized content is the key. Intel-sponsored programs provide localized content and services to connect technologies to villages, suburbs, and cities around the world to deliver access to community information, education, and healthcare.



# Why is the i7-920 suddenly out of the mix on page?Fred Ubercake 2010-02-17 09:30
Why not continue to include the i7-920 in the benchmark graphs? I don't get it.

# How can you say...Fred Ubercake 2010-02-17 09:35
..."in many tests, it even matched the Core i7-920" when the charts suddenly don't include it from the PCMark page on???

# Why Windows XP and not Win 7Julian 2010-10-11 12:54
Why are you using Windows XP and not the Win 7 64. I believe Windows 7 can achieve better results aspecialy 64 bit

# Windows 7 hadn't been released yetOlin Coles 2010-10-11 12:57
If I had to guess, it's because Microsoft Windows 7 didn't arrive until about two months after this article was published.
