Intel's C2D E6750 Revealed and BenchMarked

post #1 of 41

Intel's taken the wraps off of one of the four E6x50-series Core 2 Duo processors it first announced earlier this year, which are primarily notable for their new 1333 MHz front-side buses. The one getting all the attention at the moment is the next to top-end E6750, which clocks in at 2.66 GHz and is set to run $183 when it lands July 22nd.

The real gains, however, seem to be reserved for those willing to go the overclocking route, with Tech Report finding that they were able to push the processor all the way to 3.64GHz, making it the fastest dual-core processor they've seen to date.

Those of you paying close attention may have realized that a CPU at a 6X multiplier on a 490MHz bus will be doing a very healthy 2.94GHz—and as I said, our E6750 hit that speed at its stock voltage. That was only the beginning, though. After an epic, trial-and-error iterative process, I finally decided that the max stable clock speed for this E6750 is 3.64GHz, nearly a full gigahertz higher than stock. That's with a core voltage of 1.3875V and nothing fancier than regular old air cooling.


Throwing more voltage at the problem didn't produce any higher stable clock frequencies. I was able to get the CPU to POST and boot into Windows at up to 3.76GHz with 1.425V, but the system would crash pretty quickly after I kicked off any sort of CPU-intensive task. In fact, I had to switch from a stock Intel cooler to slightly beefier model in order to extract the last 40MHz from the E6750. With the stock cooler, the system wasn't 100% stable unless you dropped down to 3.6GHz.

But those are niggling details. We still got a near-1GHz overclock out of this thing, and we didn't have to resort to crazy-high voltages or heroic cooling measures in order to make it happen. That's a heckuva nice overclock from a relatively high speed grade CPU, and happily, its higher base FSB speed didn't get in the way; we still had a little bit of room left before hitting the motherboard's apparent bus speed ceiling.





At this speed, the E6750 is the fastest dual-core processor we've ever seen.

Hmm... screw the E4300. I'll get a Cedar Mill Celley or one of the new E21**s and then get a E6750 in August.

Thats a killer deal for something of that performance.

Not bad at all! though 3.7 (or nearly) was the most they could get out of an ES on p35 board.

E6600's are still doing 3.6+ at the same L2. Still good to know!

I'm pretty sure the E6750 is doing the same speed tange as the E6600, with a lower voltage.

What makes you so sure? Optimism is cool! Don't get me wrong! But Engineering Samples, a lot of the time, seem to produce the best results for OCing?

And, they're on a Bearlake chipset if I read correctly. That's THE current advantage right now.

Put it on an X38, a REAL motherboard, not that cheap**** ASUS.

ROFL! Heres my e6700 @ 1.65vcore, 4ghz, on my P5b-dlx.
Attachment 50804 ...gotta love the price of the 6750 though..!

Actually, from what I've seen, retail chips have done better than ES chips with the Core 2s. Not a lot better, but better.

While the Bearlake chipset may help, I still have high hopes for these chips. And at $183, it's an awesome deal.
