First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
Intel Core i7-3960X CPU
Intel's latest Extreme Edition CPU is a worthy successor to the throne, but this US$1000 processor is strictly for the enthusiast set
- Good performance increases from standard Sandy Bridge processors
Is Sandy Bridge E worth it? Even at $1000, the answer is a resounding yes--if you're using the right apps, are a dedicated overclocker, or have barrels of cash that you simply can't spend fast enough.

Intel Core i7-3960X: Synthetic benchmarks
We started our data crunching with Cinebench, a simple synthetic benchmark developed by Maxon to measure a PC's processing power. The test renders a complex 3D scene, and puts all of a processor's available cores to task, with support for up to 64 cores. The i7-3960X and i7-990X are 6-core CPUs, for a total of 12 threads, care of Intel's hyperthreading technology. The Core i7-2600K offers 4 cores, for a total of 8 threads.
Once the scene is rendered, Cinebench assigns a score — higher is better. The results in our runs were fairly straightforward. The i7-3690X earned 10.53 points, the i7-990X earned 7.27 points, and the i7-2600K earned 6.97 points. Cinebench's test runs faster with more cores at its disposal, so the superiority of the Extreme Edition parts is to be expected. Of particular interest is the relatively small gap between the Core i7-990X and the Core i7-2600K. That's the Sandy Bridge effect — the 990X is built on Intel's Clarkdale architecture, which launched back in 2010. What a difference a year makes, eh?
Next we ran PCMark 7's Productivity test, which measures a machine's performance in a few multitasking and generic office application workloads. Once the test is complete, PC Mark 7 outputs a Productivity score. The Core i7-3960X earned a score of 2487, the Core i7-990X a score of 1947, and the Core i7-2600K a score of 2327. This lineup — Sandy Bridge up front, Clarkdale trailing — proved to be a recurring theme as we moved into testing that focused on the power of each core, and not necessarily a multitude of them.
Finally, we tested with Unigine Heaven, a DirectX 11-based benchmark built on a game engine that is currently in development. Though its results aren't directly comparable to real-world gaming, it does provide a good idea of how the different processors stack up, and what you could may encounter later in the life of your machine. Here is a chart of our Unigine Heaven benchmark results.
The results here were close — for the Core i7-990X and Core i7-2600K, at least. Evidently the architecture changes between Clarkdale and Sandy Bridge have yielded to some significant performance gains. Of particular relevance to gamers, the results indicate that throwing more cores at games doesn't necessarily produce superior performance. We'll see more evidence supporting that conclusion when we look at the results of our proper games tests.
Intel Core i7-3960X: Gaming
One of the games we used in our testing was Codemasters' Dirt 3, the latest entry in the software maker's rally racing series. Dirt 3 has everything we want in a DirectX 11 game: gorgeous visuals, frenetic pacing, and lots of knobs and levers to fiddle with, to make the most of the hardware we have on hand. Here are our test results for this game.
At resolutions of 1680 by 1050 pixels and 1920 by 1080 pixels, the Core i7-3960X finished at the top of the heap, followed by the Core i7-2600K in second place, and the Core i7-990X in third. This is exactly what we expected. Applications that are designed to scale across a plethora of cores will show better results with six-core processors, as will future game engines (as we saw in the Unigine Heaven benchmark). But the most advanced games available today may not take full advantage of the extra headroom yet. And at these resolutions and settings, we're CPU-bound: We've squeezed out just about all the performance we can from the Radeon HD 6990, leaving the games to eke out as much power as they can draw from the processors.
At 2560-by-1600-pixel resolution, the Core i7-2600K actually climbed ahead of the Core i7-3690X by 5 frames per second, with 138.5 frames per second versus 133.1 fps. At the Ultra setting, the Core i7-2600K netted 76.5 frames per second, against the Core i7-3690X's 72.8.
The difference is negligible. Bear in mind that these tests run at stock speeds; the Core i7-3960X is an unlocked processor that's born and bred for overclocking, and those 4 to 5 frames per second will melt away once the CPU gets pushed beyond its meager 3.3GHz (or 3.9GHz, with Turbo Boost).
Crytek's Crysis 2 is a decidedly more strenuous game than Dirt 3, but in running it we're still CPU-bound. Here are our Crysis 2 results.
At 2560 by 1600 pixels, the Core i7-3690X maintained a frame rate of 67.4 fps, while the Core i7-2600K delivered 68.0 fps. With the settings ratcheted up another notch to Ultra, the Core i7-3690X netted 41.7 fps, to the Core i7-2600K's 41.8 fps.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
