Intel Core i5 750 Processor Review

t has been 10 months since Intel unleashed its Nehalem architecture and we showed you the Core i7 920, 940 and 965 Extreme Edition. Not much has changed in the high-end sector during this timeframe, as Core i7 processors are still brutally fast and equally expensive.

The new Intel Core i5 750 is the first release in a series of processors based on a mainstream version of the Core i7 platform. It is a quad-core part based on the "Lynnfield" architecture, fabricated using a 45nm process and utilizing the new LGA1156 platform. The Core i5 750 is set to cost just $199, it will operate at a healthy 2.66GHz and feature a whopping 8MB L3 cache, but no Hyper-Threading support will be present.

In our review we will go into more detail about Intel's reworked desktop CPU line-up, the new P55 chipset (LGA1156), and our usual load of benchmarks comparing this new processor against current Core 2 Quad offerings, the Core i7 920 and the AMD Athlon II X4 965.

Intel Core i5 and i7 Processors and P55 Express Chipset @ HotHardware.com

With today's launch of their new "Lynnfield" based Core i5 and i7 800 series processors, and the accompanying P55 Express chipset, Intel's current flagship CPU microarchitecture--codenamed Nehalem--finally trickles its way down into the mainstream computing segment. Since Nehalem first landed on the desktop in the form of the Core i7 line of processors, it has unequivocally owned the performance segment of the market. They are simply the fastest desktop processors currently available, bar none. But while the Core i7 was riding high, Intel still had the established Core 2 line-up to satisfy the mainstream, though meeting market demand for a refresh here as well was obviously the end game.

Along with the new Core i5 and Core i7 800 series processors and P55 Express chipset, also come a plethora of new features and changes. While the Core i5 and i7 800 series processors are based on Nehalem and share similar execution cores, with these new processors, Intel has changed the integrated memory controller configuration, brought PCI Express connectivity on-die, and revamped their Turbo Mode functionality to offer varying levels of increased performance depending on the type of application being used. These new processors also require a new socket, new coolers, and the P55 Express chipset--which is an elegant single-chip solution.

There's a lot of information to cover to fill you all in on the pertinent details regarding the Core i5 and i7 800 series processors and P55 Express chipset. So we'll dive right in. First up we have some specifications on tap, and then we'll follow up with architectural and platform details, and a full performance breakdown using a trio of P55-based motherboards. Lots to see; let's get to it...

Intel Lynnfield Core i5-750 & Core i7-870 Processor Review @ Hardware Canucks

After countless previews, leaked benchmarks and general, all-round excitement, Lynnfield processors are finally here and will be launched to the public. Naturally, with widespead availability comes reviews and today we will be looking at two of Intel's new "mainstream" processors: the i5 750 and the i7 870. As you will soon come to see, neither of these products exhibit what we would call mainstream performance...*

Intel Core i5 750 Core i7 870 Review @ OCC

Both of the socket 1156 Processoers reach clock speeds above 4.2 GHz with the 870 reaching almost 4.5GHz with some benchmark stability. That just about floored me, since this literally is the fastest air cooled CPU I have ever tested! Even water cooled my best i7 920 is a 4.3 GHz chip. The Kingsberg board proved to be easy to overclock and delivered excellent performance. The one thing I had hoped was fixed was the extreme temperatures delivered when you throw the current to the processor. Each chip took some voltage reach the maximum clock speeds and responded with temperatures that the CO stepping i7 920s delivered.

Intel 'Lynnfield' Core i5 750 and Core i7 870 Performance Testing

Well, Intel was not sitting back and waiting. They had plans for a dual channel memory version of Nehalem. But they wanted to make sure they provided some overlap in the way the CPU offerings worked.

This new architecture would not just be a lower powered version of Nehalem, it was going to be something very different and will set the mainstream world on its ear.

Intel Core i5 750 & i7 870 Review

Overall, both new flavors of Lynnfield are great processors. At stock speeds, the i5 750 doesn't eclipse AMD's offerings as far as performance goes, but clock-for-clock Intel is far ahead. In fact, their 2.66 GHz processor manages to keep up and beat AMD's 3.4 GHz chip, albeit with Turbo which does provide a notable performance boost.

Intel Core i5 750 CPU review @ Elite Bastards

The result of these changes to Lynnfield's interconnect and memory controller is a reduced pin count from the hefty 1366 pins required by Nehalem down to "just" 1156 for these new CPUs. This is great news from a manufacturing cost perspective, but slightly less exciting news for those of you who hate the forever-changing nature of CPU sockets, as Lynnfield brings with it just such a new socket to suit its reduced pin count. Thus, to run one of these new processors you'll need an LGA 1156 motherboard (which currently means anything using Intel's P55 chipset) and a CPU cooler with a Socket LGA 1156 mounting mechanism.

On a more fundemental level, all of Intel's Lynnfied CPUs at launch time feature four fully functional CPU cores, while all of these parts also support Intel's "Turbo Mode", which allows the CPU to intelligently overclock its CPU cores under certain circumstances by 133MHz provided it doesn't take the processor outside of its thermal or power specifications. HyperThreading is also supported, albeit only on some Lynnfield CPUs - Any Core i7 monikered Lynnfield CPUs will be able to use HyperThreading to effectively give the processor eight virtual cores, while all Core i5 branded CPUs lose out on this functionality.

Intel Core i5-750 LGA1156 Processor Review @ Benchmark Reviews

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 and, as such, 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.

Nehalem for all - Intel Core i5 and Core i7 socket 1156 on the test

On 3 November 2008, presented with the Intel Bloomfield processors, its first Core i7 family. The discussions under the code name Nehalem models ensured in advance for a variety of headlines, presented Intel with the new CPUs, but a new architecture before. The starting signal for this time was certainly a little under pressure.

Intel has in fact imposed its own internal timetable, which called it "Tick Tock" and provides that the company excels in an annual cycle, with new technology updates. So in 2007 was still the manufactured in 45 nm Penryn - now represented in various derivatives as Core 2 Duo and Core 2 Quad on the market - it had to give in 2008 with Nehalem Tock - a new architecture so - otherwise it would be the compliance of the system guilty remained.

Intel Core i5 And Core i7: Intel’s Mainstream Magnum Opus

Intel’s emphasis right now is on Clarkdale, the Nehalem-based mainstream lineup centering on a 32nm process shrink. Clarkdale will be the foundation on which upcoming Core i5 and Core i3 CPUs are based. It’s a big deal for Intel. So big, in fact, that I was told jokingly two weeks before the Lynnfield launch that the whole company had been focusing on Clarkdale, not the Core i5 and Core i7 we’re seeing today.

Of course, that’s only really funny for the folks who’ve already seen how the Lynnfield-based processors actually perform and know they’re not as anemic as an enthusiast might expect, given the fact that Intel is aggressively pursuing integration, aiming for a SoC-type design in the not-so-distant future.

But Clarkdale is six months away, at least. Today is all about Lynnfield—the Core i5 and Core i7 CPUs for Intel’s LGA 1156 interface.

Intel's Core i7 870 & i5 750, Lynnfield: Harder, Better, Faster Stronger

We get three Lynnfield CPUs today: the Core i7 870, Core i7 860 and the Core i5 750. Intel's branding folks told us that the naming would make sense one we saw the rest of the "Core" parts introduced; yeah that was pretty much a lie. At least there aren't any overlapping part numbers (e.g. Core i5 860 and Core i7 860).

The i7 in this case denotes four cores + Hyper Threading, the i5 means four cores but no Hyper Threading. The rules get more complicated as you bring notebooks into the fray but let's momentarily bask in marginal simplicity.

Gigabyte P55-UD6 and P55M-UD4 Motherboard Reviews @ Legit Reviews

Today for the P55 launch we have two of Gigabyte's 11 P55 motherboards up for review. The GA-P55-UD6 is their high-end P55 motherboard with every feature known to man crammed onto an ATX motherboard. Ok, maybe not a every feature but close. The GA-P55M-UD4 is their high-end P55 mATX motherboard featuring the vast majority of the options on the GA-P55-UD6 albeit laid out on a compact mATX canvas. The only thing missing on the GA-P55M-UD4 is the TPM security module, the onboard LED debug reader, half(12) of the power phases, and a few expansion slots which might sound like a lot but in reality isn't nearly that much...

Intel Core i5 750 Review - XSReviews

The introduction of the Core i7 range of processors late last year was the beginning of the Nehalem family. The processors have had a mixed reception and it is fair to say that although the new series has been impressive performance wise, the pricing was and still is too much for many users. After all, the LGA1366 socket requires not only the processor but also an X58 motherboard and triple channel DDR3 memory.
