I5 750 in for a ride?

Core i5 650 ''Clarkdale'' Reaches 4.70 GHz on Air-Cooling
Intel's socket LGA-1156 quad-core processors are closely trailed by the Intel's first processors based on the 32 nm manufacturing process: Core i5 and Core i3 "Clarkdale" dual-core processors. Engineering samples of these processors were evaluated as early as Q2 2009, but one of the first attempts to show the processors' overclocking potential using air-cooling was made very recently. Even prior to that, a low-voltage overclocking feat by Coolaler showed how engineering samples didn't particularly struggle reaching clock speeds close to 4.00 GHz with vCore as low as 0.832V. Romanian tech community Lab501. Lab501 community leader "Monstru" tested the overclocking headroom of a Core i5 650 LGA-1156 dual-core processor (engineering sample) with air-cooling.

The test-bed included a Gigabyte P55 motherboard, the Core i5 650 processor was cooled by a Noctua NH-U12P, onto which a Coolink SWIF 2 120P fan was strapped. A clock speed of 4.70 GHz (25 x 188 MHz) was achieved (nearly 50% over the stock clock speed of 3.20 GHz). A core voltage of 1.424V was used. A point here to note however, is that the retail Core i5 650 will come with an upwards-locked bus frequency multiplier of 24 (24 x 133 MHz = 3.20 GHz). The processor at 4.70 GHz, was Prime95-stable for over 30 minutes. With an ambient temperature of 24 °C, the two cores heated up to 77 and 68 °C, not to forget that the processor was being air-cooled. Although with the use of an engineering sample (since the retail launch of this processor is tentatively three months away), the scope for inference of this feat is limited, it gives you a coarse indication that Intel is keeping the trend of ferociously fast dual-core processors alive. High(er) overclocking headroom on air-cooling is the fruition of the 32 nm process. Slated for Q1 2010, the siblings (and cousins) of the Core i5 650 include Core i5 660/661 (3.33 GHz, HTT), Core i5 670 (3.46 GHz, HTT), Core i3 540 (3.06 GHz, no HTT), Core i3 530 (2.93 GHz, no HTT), and Pentium G6950 (2.80 GHz, no HTT). Details of the series can be found here.

and, the upcoming I3 & I5's seems to have higher stock speed than it's present counterparts.

•Core i3 530 -2.93 GHz
•Core i3 540 -3.06 GHz
•Core i5 650 -3.20 GHz, with Turbo Boost speed of 3.43 GHz
•Core i5 660 -3.33 GHz, with Turbo Boost speed of 3.60 GHz
•Core i5 670 -3.43 GHz, with Turbo Boost speed of 3.73 GHz

damn intel for keeping us upgrading

~4ghz @ ~0.8v not bad, hope these dont perform like low end celerons

 

[reygjabla]

Doesn't look like upgrading to me. "Downgrading" would be more appropriate. Quite confusing though.

I'm pretty sure there are going to be a few that skip the quoted text and look purely at the clock speeds, for their benefit...

These are dual core.

I don't think anyone that has an i750/i860 around 4Ghz is going to regret their early purchase by the time these dual core variants come out

+1 just what I was about to put.

 

[reygjabla]

The I5 variant has HT and Turbo if you noticed.

 

[Ducky Spud]

I would probably still consider one of those over my 750. Just game on my PC really, rarely do anything else which will push it and in my experience I higher clocked dual core tends to out perform a slower quad core. Still, will wait and see actual results when it is released, these are engineering samples, the results arent going to be that good for the majority of chips when theyre released

 

[Cesar67]

Any speculative prices for these chips ?

 

[reygjabla]

Initial pricing qoute.

Core i5 models have their model number series beginning in the 600 series, and take off where the 500 series Core i3 processors leave (next to Core i3 530, is Core i5 640). Price-wise, Core i3 dual-core processors tentatively range between US $123~$143, while Core i5 dual-core ones between $176~$284. All these processors feature two cores, and HyperThreading technology enabling four logical CPUs (threads). Each core has a dedicated L2 cache of 256 KB, while a 4 MB L3 cache is shared between two cores.

Finally, Intel's first sub-$100 Pentium dual-core offering based on this architecture will be called Pentium G6950. Clocked at 2.80 GHz, its feature-set is nearly identical to that of the Core i3, except for that it has 3 MB of available L3 cache, and HyperThreading is excluded from the feature-set. All Clarkdale based processors so far, carry TDP rating of 73W.

I imagine they will be replacing the E8400, E8500 and E8600 maybe? So similary to those would be my guess, around £120, £140 and £190. Though I could just have it completely wrong haha

 

[maddness]

i reckon the prices will be high, pretty much the above

intel will be pushing the fact that these are dual core but at higher clock speeds, whereas quads are lower speeds but 4 cores

 

[reygjabla]

Could be one reason though why they're pushing present stocks with giveaways.
Dual core with HT and Turbo with lower TDP, what else can you ask for if you're just gaming?

 

[maddness]

wonder if highly clocked duallys will give quads a run like in the previous gen

5ghz dually on air would be good for gaming i'd imagine

You wont be able to game fast enough to keep up with that

 

[reygjabla]

You don't need to maximise your usage, otherwise, your system will start to lag. It just nice to know your system has the power in case you need it, rather than knowing, your system does'nt have enough power when the need comes, leaving you no other options but to upgrade.
