Fundamentally, it's the same chip as the much cheaper E model which performed so well in our original benchmarks. So, it's packed with a virtually identical set of Athlon bashing features, including a dual-core architecture, topped with 4MB of shared L2 cache, a four issue-wide instruction core and massively enhanced SSE instruction handling. Indeed, it differs only in offering an overclocking-friendly unlocked CPU multiplier and a bump in clockspeed from the E's 2.
Making matters worse, Intel has also announced a Xeon-branded workstation variant of this chip which sports a 3GHz clockspeed and 1. But if our review sample is anything to go by, the ultimate insult is its overclocking potential.
Our 2. Keep in mind that we had a very limited amount of time with the hardware as to not alert anyone that it was missing and being used for things it shouldn't be not yet at least , so we weren't able to run our full suite of tests. We apologize in advance and promise we'll have more when Conroe launches, but for now enjoy. In case we weren't clear: we acquired, built, installed and tested these two test systems entirely on our own and without the help of Intel.

Our testing methods As ever, we did our best to deliver clean benchmark numbers. Tests were run at least three times, and the results were averaged. In some cases, getting the results meant simulating a slower chip with a faster one. For instance, our Core 2 Duo E and E processors are actually a Core 2 Extreme X processor clocked down to the appropriate speeds. Their performance should be identical to that of the real thing.
Those of you who are up in Canada will definitely want to check them out as potential source of PC hardware and related goodies. Thanks to Corsair for providing us with memory for our testing. Their products and support are far and away superior to generic, no-name memory. Thanks to OCZ for providing these units for our use in testing. Vertical refresh sync vsync was disabled. The tests and methods we employ are generally publicly available and reproducible.
If you have questions about our methods, hit our forums to talk with us about them. Each gameplay sequence lasted 60 seconds.
This method has the advantage of simulating real gameplay quite closely, but it comes at the expense of precise repeatability. We believe five sample sessions are sufficient to get reasonably consistent results.
Notice the little green plot with four lines above the benchmark results. Thus begins a long series of tests results in which the Core 2 Extreme QX leads the field in performance. Shadow quality was set to very low, and motion blur was enabled at medium quality. The top finishers bunch up tightly again in R6: Vegas , and the QX again leads the pack. Its most direct competition, the Quad FX-based Athlon 64 FX, trails by three frames per second—practically nothing.
Supreme Commander This game is multithreaded and can actually take advantage of more than two processor cores, making it a rare commodity indeed. I was also developing the first signs of extreme RTS addiction—a grave condition indeed. I found myself analyzing unit types and lusting after level-two engineer bots. Normally, we prefer to test games with audio enabled, but we made an exception here.
Yep, you guessed it, the QX is fastest across the board. As you may have noticed, our results for the render test and the FPS numbers look to be limited somewhat by the graphics card we used. Valve Source engine particle simulation Next up are a couple of tests we picked up during a visit to Valve Software , the developers of the Half-Life games.
The first of those tests runs a particle simulation inside of the Source engine. Most games today use particle systems to create effects like smoke, steam, and fire, but the realism and interactivity of those effects is limited by the available computing horsepower. Valve uses VRAD to precompute lighting that goes into its games. It does, however, show how multiple CPU cores can speed up game development. Were you expecting anything else? The QX sticks to the top spot like peanut butter to the roof of your mouth.
The Panorama Factory The Panorama Factory handles an increasingly popular image processing task: joining together multiple images to create a wide-aspect panorama. I asked it to join four pictures, each eight megapixels, into a glorious panorama of the interior of Damage Labs. Reinert H. Eight of the 12 functions in the test are multithreaded, and in this latest revision, five of those eight functions use four threads.
Windows Media Encoder x64 Edition Windows Media Encoder is one of the few popular video encoding tools that uses four threads to take advantage of quad-core systems, and it comes in a bit version.
Both audio codecs have a variable bitrate peak of Kbps. Of course, multithreading works even better on multi-core processors. You can download a paper in Word format describing the programming effort. That is, the psycho-acoustic analysis happens one frame ahead of everything else, and its results are buffered for later use by the second thread. We have results for two different bit versions of LAME MT from different compilers, one from Microsoft and one from Intel, doing two different types of encoding, variable bit rate and constant bit rate.
This test runs with just a single thread and then with as many threads as CPU cores are available. The latest beta bit executable is still quite a bit slower than the 3. The FX finishes rendering the scene 10 seconds sooner. MyriMatch Our benchmarks sometimes come from unexpected places, and such is the case with this one. David Tabb is a friend of mine from high school and a long-time TR reader.
In shotgun proteomics, researchers digest complex mixtures of proteins into peptides, separate them by liquid chromatography, and analyze them by tandem mass spectrometers. This creates data sets containing tens of thousands of spectra that can be identified to peptide sequences drawn from the known genomes for most lab organisms.
Recently, David Tabb and Matthew Chambers at Vanderbilt University developed MyriMatch , an algorithm that can exploit multiple cores and multiple computers for this matching. Source code and binaries of MyriMatch are publicly available. In this test, tandem mass spectra from a Thermo LTQ mass spectrometer are identified to peptides generated from the proteins of S.
The data set was provided by Andy Link at Vanderbilt University. MyriMatch uses threading to accelerate the handling of protein sequences. The database read into memory is separated into a number of jobs, typically the number of threads multiplied by When a thread finishes handling all proteins in the current job, it accepts another job from the queue.
This technique is intended to minimize synchronization overhead between threads and minimize CPU idle time. The most important news for us is that MyriMatch is a widely multithreaded real-world application that we can use with a relevant data set.
This benchmark has been available to the public for some time in single-threaded form, but Charles was kind enough to put together a multithreaded version of the benchmark for us with a larger data set. He has also put a web page online with a downloadable version of the multithreaded benchmark, a description, and some results here. I believe the score you see there at almost 3Hz comes from our eight-core Clovertown test system.
In this test, the application is basically doing analysis of airflow over an aircraft wing. I will step out of the way and let Charles explain the rest:. The CFD grid contains 1. Functionality, performance, and other benefits of this feature may vary depending on system configuration. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. System and Maximum TDP is based on worst case scenarios.
