Dell Inspiron 15 Application Performance

Given the 4GB of memory and powerful quad-threaded Intel Core i5-520M processor, it's reasonable to expect our Inspiron 15 review unit will tear through most processor-related tasks with relative ease. To refresh, here's how our Inspiron 15 is configured:

Dell Inspiron 1564 Testbed
Processor Intel Core i5 520M
(2x2.4GHz, 32nm, 3MB L3, Turbo to 2.83GHz, 35W)
Memory 2x2GB DDR3-1066 (Max 2x4GB)
Graphics ATI Mobility Radeon HD 4330 512MB GDDR3
(80 SPs, 450/1.2GHz Core/RAM clocks)
Display 15.6" LED Glossy 16:9 768p (1366x768)
Hard Drive(s) 320GB 5400RPM HDD
Optical Drive 8x DVDR SuperMulti
Battery 6-Cell, 12V, 48Wh battery
"Up to 4 Hours"
Operating System Windows 7 Home Premium 64-bit
Pricing $979 as configured

For basic performance we've tested the Inspiron 15 in PCMark05 and PCMark Vantage, and in both programs you'll see it simply excels, blowing past the Intel Core 2 powered competition. We've also included results for video encoding, 3D rendering, and web browser performance.

Intel made some very big strides with the Arrandale-based Intel Core i5 processors, and the i5-520M's performance here is proof of that, showing leads of 20% to 65% in the various benchmarks compared to the next-fastest notebook (Dell Studio 14z/P8600). Suffice it to say, it's very fast and more than up to any processor-related task you want to throw at it. The only way you'll get more performance in a laptop is to move to a quad-core CPU, and even then it will only be in tasks that can leverage multi-threading effectively.

    1. Well, I have seen both (current) displays and I found Acer's somewhat better + webcams were always great in the few Acers I've come across recently (in 2-3 years) whereas Dell's track record is rather spotty there...

    2. There's an i5-520M version of it, for $850 but I don't think it worth $100 at all - IMO you would be better off rather spending it on a small SSD for the system and moving the 500GB to an external case instead...

    3. Acer is fully-featured, unlike this one which, as the writer said it, feels stripped down.

    4. The new DX11 mobile ATI chip gives you full 8-channel audio over HDMI which is a big plus for HTPC use, even if occasional.

    5. Of course, this new mobile chip will drive 13x76 resolution just fine even in new games.

    Why should that be an external case? Just replace the DVD drive with a caddy holding the SSD/HDD and move the DVD drive to the external case.

    I'm not a big fan of the 16:9 laptop screen. Seems like things have gone backwards when you have fewer vertical pixels that the old 1024 x 768 screens many years ago.

    What I've heard is that it's all about maximizing the number of LCD panels you can get from the glass substrate... if you use 16:10 each panel is 10% larger, and the source substrate size has been optimized lately for 16:9 production.

    Might be true, but it still sucks. Kinda like just about everything relating to laptop LCDs these days.

    Dell Inspiron 17 inch with corei5 is the best laptop .. Dell's designers seem to understand the importance of user experience extending beyond simple metrics like system performance... I THINK IT IS A GREAT DEAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!
