[hothardware] Intel Core 2 Duo E7200 review

It has been surprising and frankly somewhat satisfying to see the success to date of the "Wolfdale" core architecture in Intel’s Core 2 lineup of processors. "Wolfdale" is Intel’s first 45nm based dual-core design, and is an interesting product beyond first glance. When it was first announced, there was a bit of doubt throughout the industry of the chip’s viability in the market. The doubt was that it would be foolish of Intel put major weight behind a dual-core processor architecture, as the future is clearly quad-core processors and beyond. More cores are always better, right? Why would Intel continue pushing dual-core models when quad-core models are getting more and more cost efficient? That's a fair question.

Once we got our first “Wolfdale†chips in for testing, we realized that a modern dual-core processor can still bring exceptional performance for today’s high-end machines. While quad-cores definitely have more appeal for the heavy multi-tasking power user, dual-cores can typically accomplish most tasks with performance to spare, but can do so with much lower power consumption and heat production. In addition, if your application of choice is only coded to handle two processor cores, it can actually run faster on a highly-clocked dual-core compared to a mid-range clocked quad-core. While the wave of multi-core software is rising every day, we still haven’t seen truly compelling numbers in main stream applications showing that quad-core processors are worth their premiums for many average, everyday computing scenarios.

In any case, despite initial availability issues, Intel’s new E-series processors based on this new “Wolfdale†architecture ended up being a big hit, and chips are still in high-demand, months after their initial release. Now that the product line is beginning to become available in volume, we’re seeing Intel flesh out their Core 2 Duo product line with the entry of the first truly low-cost “Wolfdale†processor release to date, Intel’s Core 2 Duo E7200.

The Core 2 Duo E7200 is a bit of an anomaly on Intel’s dual-core product lineup, much like the Core 2 Quad Q9300 is the anomaly for the quad-core product lineup. Both the E7200 and Q9300 are the only models in their lineups which have half the L2 cache of other models in their families. In addition, both run at 2.5 GHz clock speeds and both are priced very competitively for the performance they offer. The E7200 is a based on a simple, modern dual-core design, whereas the Q9300 uses two of these processor dies to create a quad-core version . Beyond the raw core count, the chips are nearly identical. With the release of the Core 2 Duo E7200, it’s now possible to get a fast “Wolfdale†dual-core chip for about $130, about half the price of today’s high-end “Wolfdale†models. Let’s see if this newbie can live up to the high-bar set by preceding 45nm dual-core parts from Intel.

A much more useful review than the earlier TweakTown review, and no funny graphs. They also try to overclock it, gaining an interesting 3.5GHz stable with a cooler I am not familiar with..

What an enticing little chip.

Looks looks a nice chip. I would have thought they could achieve a higher clock though, considering it has a 9.5x multi.

For testing, we used the massive Coolermaster Gemini II cooling system with low-speed cooling fans.

Now that we have thoroughly evaluated the GeminII there isn't much good to say about it, at least compared to the top coolers we have been testing recently. The GeminII is not a bad cooler; it is just not the great cooler we expected it to be. We have tested 21 cooler configurations in the last few months at AnandTech, and nine of those configurations overclock better than GeminII with the same CPU. That is before we even take in to account the fact that the GeminII uses two fans to, in many case, perform worse than a single 120mm fan.
Someone really should put a TRUE on this little guy.

They were pushing 60c with the temps after overclock, but isn't 1.4v too much for a 45nm dual?

hmmm....

I think I'm going to get one, and put it on water, in a nice P35 board, and see what it does...



newegg 's got them for 130 ish, so its worth checking it out... for me anyways...
good enough

the bad thing to is that my gigabyte 965p-ds3p bios update don´t support that cpu
my only choice is to buy c2d 8200 for 143€ (euros)
the c2d e7200 114€

I always thought so. I thought the general consensus wa that 1.36 some odd volts was the max you should do 24/7. If they need 1.4 for 3.5 then that is quite a lot.

I don't trust any of this, afaik the only real difference between the E7200 and the E8400 is the extra cache, and unless something has drastically changed with the move to 45nm a 3.5GHz E7200 shouldn't be slower than the 3GHz E8400. I'm no stranger to cache difference, but clock for clock my e2180 isn't that much slower than an e6750 at the same clock speeds.

And then theres the fact that he described overclocking as "a simple boost to the vCore levels" despite the fact that 1.42V would kill the chip in a matter of weeks. He seems to know nothing about 45nm.
