At KitGuru we spend a lot of our time playing with high end hardware, and it can be disheartening for many readers. In the cold hard ‘real world' not everyone can afford a Core i7 980X with SLI'd GTX480's and to be honest, for most people this is totally overkill anyway. Killer performance shouldn't cost a fortune and this is the focus of today's write up.

Today we are trying something new – we want to help you build a Core i5 system which is not only capable of gaming, but media, 3d rendering and video editing duties also. We will hand select components we know will overclock well, but we also want to limit bios tweaking, a scary part of building a system for many people. There is a huge audience who want to build their own system, but don't want to learn a wealth of bios settings. We will guarantee today you can achieve a 1.4ghz overclock without breaking a sweat.

With the wealth of hardware options available in today's tech environment it is relatively easy to built a kick ass system for under a grand. What we have in store for you today is an Intel Core i5 quad core running at 4.2ghz with 4GB of 2GHZ DDR3, a 1080p LED screen, SSD drive, all without breaking the bank. KitGuru shows you how.

Intel’s special ‘K’ edition CPU's were made available to the world’s top technology sites prior to launch and we have been working our samples harder than we’ve ever worked a CPU before. It's been serious business testing the best chip Intel's ever made. And that's what the Core i7 875 ‘Special K' Edition is.  The best chip ever.

Today we’re focused on presenting the KitGuru audience with our preliminary findings for Intel’s Core i7 875k and, as the headline tells you, the bottom line is that it held firm at 4.8Ghz on air!

That it ships with a stock clock of 2.93Ghz lets you know just how madly over-engineered these parts are.

Bear in mind that we achieved these clocks with the standard, reference, Intel-manufactured P55 chipset mainboard, where the BIOS had a lot of features – but not every little tweak and trick was exposed the way that us KitGuru’s like it. With a mature board from an aggressive 3rd party, there is a chance that Intel’s Core i7 875 ‘special K’ edition could go even further.

That said, we were feeding in ~1.4v, so be careful as temperatures stabilised around 87 degrees. High, but no cause for panic.

At this stage, we’re going to touch on price points. The whole IT industry has been hit by the ever-strengthening dollar and that’s pushed the price of the Core i7 875 much higher than Intel would have wanted. We’re still expecting a UK street price just over £275, but that could change.

You also need to bear in mind that this processor has been designed around a dual-channel memory system – so the price for mainboard and Ram will be lower than a comparable Core i7 930 system.

Preamble over. Let’s get down to the only thing that matters.

Enthusiasts feel the need. The need for speed. And the 875 delivers speed in BIG buckets.

Our bench test setup used the Austrian sandwich cooler from Noctua as well as some specially selected memory from Crucial’s Ballistics team (lovely Tracer modules). We began slowly and spent a lot of time feeling our way through the processor, its likes/dislikes as far as voltages go and we spent a lot of time making sure the cooling solution was optimised, in terms of clamping pressure, air flow and TIM.

At stock clocks, the 875 punches at exactly the level you would expect for a quad core processor at 2.93Ghz. Then the fun started. In the coming days, we will hand hold you through the detail of our work with the processor, but – for now – let’s cheat completely and skip ahead to the final ‘OC chapter' in the book.

On air, running solid benchmarks for hours, KitGuru had the Intel Core i5-875 Special ‘K’ Edition breezing along at 4.8Ghz.

We'll say that again. FOUR POINT EIGHT GIGAHURTZ.  H-U-R-T-Z.

We’ve spoken with some of the UK’s top system builders and cross-referenced our results. They are telling us that, in the right environment, they get comparable scores to us – but if they were shipping across the country and needed to guarantee the system for 12 months, then they would opt for a shade under 4.2Ghz.

Honestly, With the Intel Core i7 875 running solidly at 4.8Ghz, that is a monster overclock of around 64%.

On air!

Does that impact performance?  Oh yes. Yes indeed.

With applications like Cinebench 11.5, the scores were shown to be absolutely in line with the clock speed:-

Here’s a side-by-side comparison of the decent, 6GB, Core i7 930 system against the kind of 4Gb Core i5 875 Special ‘K’ Edition you’d need to achieve up tp 4.8Ghz.

Core i7 930 Rig
Core i7 875 Rig
Core i7
£235
£275
Mainboard
£220
£155
(6gb/4gb)
£150
£100
Total
£605
£530

Based on our preliminary performance figures and the street price shown, Intel has a beast and a half on its hands with the Core i7 875k ‘Special K' Edition.

KitGuru says: We love it. Every day of the week and three times on a Sunday. It's the best chip Intel has ever produced. To start with, the Intel BIOS felt weird and cramped. But, after days coaxing the settings, we got the reaction we were looking for. There’s every chance that we’ll be able to get it a smidgen higher than 4.8GHz with time – and certainly with liquid cooling.   But remember true believers: Salivating is NOT liquid cooling!

From the dark days of the Pentium 4, Intel has come a long way in its attitude toward the overclocking community. From ‘all overclocks must be stopped' to ‘the clocks that rock'. But how much will the latest overclocking chip of the Core generation set you back?

Setting the price of a chip is a delicate science. One that Intel has mastered in recent years. For the enthusiast community, sales of the i7 series have centred on the 920 and now the 930.

While the ultra high-end 965, 975 and 980 chips have found favour with the workstation and design community, the i7-860 has been left behind as the poor cousin that no one seems to want. It has been unfortunately sandwiched between the higher performing 930 and cheaper Core i5 750.

With the ‘Special K’ version, Intel is looking to change that, by completely unlocking the internals and pricing it to compete. So, the killer question is, “Just how much will it cost?”. KitGuru now believes that the UK street price will be around £275. That makes it up to £50 more expensive than the triple channel i7-930. Is the price point right ?

KitGuru says: Word on the (virtual) street indicated that the Intel Core i7-875k processor will reach at least 4.2Ghz on air. However, the Core i5-750 is a shade over £150 and can already clock to 4GHz. Until we see final benchmarking data, it’s going to be hard to justify the additional £125.
