It absolutely flattens AMD's Athlon 64 FX- 62, while remaining cool, calm and collected throughout.

Reviews Word on the street for the Intel Core2 X6800

Our 2.66GHz E6700 managed 3.2GHz using the same setup.

What People Are Saying Give it to me straight

Socket Type

A 300 point lead for the X6800 over the FX-62 in the overall benchmark test means that the top spots at the ORB will now be filled with Core 2 Duo results.

By adding more L2 cache, support for Enhanced Memory 64 Technology (EM64T), Execute Disable Bit, and the combination of EIST (Enhanced Intel Speedstep Technology), C1E (Enhanced Halt State), and TM2 (Thermal Monitor 2) the updated Prescott was finally looking like a production processor from Intel.
by Legit Reviews (Jul, 2006)
Intel was able to get a healty performance increase with Conroe and was able to do so using 22W less power at idle when compared to their Pressler core.

Since I keep my computer on nearly 24 hours a day and fold 24/7 on it for the Legit Folding Team (Team #38296) I would save roughly ~$60 per year by running an X6800 versus the FX-62.

From our testing the flagship AMD processor consumes roughly 45W more power than the fastest Intel dual-core processor, the Intel Core 2 Extreme processor X6800.
by Legit Reviews (Jul, 2006)
We have been so used to seeing AMD take the lead in these tests, that is almost seems wrong to say that the best they can do with their FX-62 is third place among these 5 cpus being tested.
by Legit Reviews (Jul, 2006)


For now the victory flag goes back to Intel with one of the most impressive new cores that we have seen to day.
by Legit Reviews (Jul, 2006)
Unlike the mobile Core Duo and Core Solo, the desktop chips have naming scheme distinction between the number of cores.
by Legit Reviews (Jul, 2006)
Intel has hit a home run with their lastest core and has them ramped up and ready to roll out the door.
by Legit Reviews (Jul, 2006)


It wasn't a great overclocker and was an early stepping so it wasn't included in our performance testing.
by Legit Reviews (Jul, 2006)
Fundamentally, it's the same chip as the much cheaper E6700 model which performed so well in our original benchmarks.
by Tech Radar (Aug, 2006)
It is because of this and the fact that Intel has taken the performance lead back from AMD that we gladly award the Intel "Conroe" processor the Legit Reviews Editor's Choice!

Type of CPU

We had the chance to talk with AMD on the phone today they promised Legit Reviews that AMD will have an agressive price move come in July and went on to say that AMD will not give up the lead in price versus perfomance.
by Legit Reviews (Jul, 2006)
All of these parts follow Intel's new processor numbering scheme, introduced when the Core Duo mobile processor family arrived earlier this year.
by Legit Reviews (Jul, 2006)
While Intel was busy updating their desktop processor lines, AMD was busy playing catch up and consumers were jumping ship.
