Intel 5th Gen Core Series Performance Preview With 2015 Dell XPS 13 97

Posted by Soulskill from the separating-fact-from-marketing dept.
MojoKid writes: Intel's strategically timed CES 2015 launch of their new 5th Gen Core Series processors for notebooks was met with a reasonably warm reception, though it's always difficult to rise above the noise of CES chatter. Performance claims for Intel's new chip promise major gains in graphics and more modest increases in standard compute applications. However, the biggest bet Intel placed on the new Broadwell-U architecture is performance-per-watt throughput and battery life in premium notebook products that are now in production with major OEM partners. A few manufacturers were early out of the gate with new Core i5 5XXX series-based machines, however, none of the major players caught the same kind of buzz that Dell received, with the introduction of their new XPS 13 Ultrabook with its near bezel-less 13-inch WQHD (3200X1800) display. As expected, the Core i5-5200U in this machine offered performance gains of anywhere from 10 to 20 percent, in round numbers, depending on the benchmark. In gaming and graphics testing is where the new 5200U chip took the largest lead over the previous gen Core i5-4200U CPU, which is one of the most common processors found in typical ultrabook style 13-inch machines.

    So the laptop is full of ridiculously advanced tech, even in the graphics department but the keyboard looks cheap and really to me the more travel there is, the better. Won't somebody make a laptop with thick keys?, or at least some "high end keyboard" option. Seems like there's $5 worth of keyboard there, on a one-piece computer that's closer to $1000. What if there were $50 worth of keyboard, I wonder.
    Providing a right ctrl key is nice I guess, but I wonder when we'll see a genius including a right Fn key so we can do single-handed page up, page down, end and home.

  • The i5 has the same thermal power as the i7. The i5 generally runs at a slight speed advantage to the i7. The i7 has twice the cores of the i5. So for single threaded tasks, the i5 may be a hair faster. But for multithreads (getting more common, despite the complaints about it here), the i7 will be almost twice as fast as the i5.

    Call me when they have the i7. For no more heat and exactly the same battery life, I'd rather pay for the i7.

    • i7-4790t (tray, oem only). 45 watts and truly a fanless buildable system (I did one, its great).

      hard to find that chip. pretty much, no one has it (anymore). $300 or more, if you can find it. but wow, 45w on an i7 with 8 real cores. its great to do 'make -j9' on a fanless 'htpc' ;)

          It's not *that* impressive - laptop i7s are 47W parts and they're doubtless *very* closely related. There are also some 37W quad-core mobile i7s, but they have low clock rates in comparison.

        I have an i7-3612QM in my laptop. Sure, you wouldn't likely see that in a ultralite. But comparing the i5, the i7 runs a little slower to keep 4 cores in the same heat as the 2-core i5. For multithread, the i7 will be much better. With single-thread only, and one program at a time, the i5 may have a slight advantage. A dual core i5 vs dual core i7, there's not as much difference.

          Intel's "Turbo boost" will let 1 busy core run at a faster clock rate than if all cores were busy. I would have thought this would result in it running an i7 at the same speed as the comprable i5 under a single threaded task.

Then you'd have a bunch of utlrabooks and a bunch of high power ones, but not in remotely the same sort of quantity.

    • By the way, it's not correct that every mobile i7 has 4 cores. The low power i7 CPUs have only two cores. Considering that Broadwell is focusing on low power parts (less than 30W TDP), there will not be a quad core Broadwell Core i7. If you need a quad core i7, then you have to get the Haswell part.
