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.

    I received my 1464 the day you reviewed the 1564. It's the same laptop but with a 14" screen.

    Mine has the Core i5 430.

    I use an external monitor 95% of the time so the poor quality screen isn't a problem. It's actually better then my old HP. I don't mind the lack of expresscard since I've never used it. I use a usb hub for my peripherals so only 3 ports is fine. I actually didn't notice the 100mbit ethernet, but oh well. I'll eventually upgrade to N wireless but my router is G so the G doesn't bother me for now. I'm happy with the quality and features. All I wanted was a cheap 14" laptop with HDMI and the Core i5 without a graphics card. That's what I got.

    BUT, the fan on my laptop is constantly turning on and off. It is SO annoying in a quiet room and it is driving me nuts. I'm sitting here in my office not working, and thinking of a way to build a stand for the laptop with a quiet 80mm fan that blows directly into the air inlet so the fan will never ramp up. I've studied the CPU and the fan turns on at 27C (why can't it go to 50 before turning on?) and turns off at 20C a minute later. Then it climbs to 27, the fan turns on, and then it turns off at 20C.

    I can't find a fan control program that is able to control the fans. I can't find a program that is able to undervolt the processor. I just spent $30 on a laptop cooler with movable fans. If that doesn't work I'm building my own with some wood, a 5V wall wort, and some foam. Dell, it is UNACCEPTABLE to build a computer that changes the way it sounds just sitting there doing nothing. Learn how to program a fan control system. This is my last Dell. Every notebook from now on, I'll have to touch and wait around for the fan to stabilize before I buy it.

    I'm looking at the new Studio 14 with the Core i3/i5 CPUs but haven't found a good review of it yet. It's got the same CPUs but can be had with a Radeon 4530 and 7200 RPM drives.

    "Dell's designers seem to understand the importance of user experience extending beyond simple metrics like system performance"

    So Dell's designers are much MUCH smarter than most of the DT readers :P

    I've been using the similar equiped (ports wise) Inspiron 13Z for the past 5 months and to be honest I've havent missed having a PCMCIA/Express port or a fourth USB port at all.

    I think Dell have done some research on what parts most users need/use and found that (especially Express port) they just arent needed.

    This range of Inspirons are really great.

    this article was hard to read... far too wordy... detailed, but not enjoyable

    No 7,200 RPM HD
    No Gigabit Ethernet
    4 Hour Battery
    Sub $1,000 cost
    If the ending price was $579, it would be a good deal.

    I have had 2 of the older 1545's, one with the 768 screen and one with the 1600x900 screen... spring for the better screen, its well worth the price, and these things can be had for much cheaper through the outlet.

    ...did Dell actually ask you to "review" this unit? Because if they did, they are not happy, I think. :D

    Joking aside please, take a look at this gem: http://www.jr.com/acer-computer/pe/ACE_AS5740G6979...">http://www.jr.com/acer-computer/pe/ACE_AS5740G6979...

    Good brand, killer i5-based (2.26GHz) config including latest DX11 Mobility Radeon 5650 1GB, for $750 (faster 2.4GHz adds $100 more) - I'm pretty sure anyone interested in a decent laptop would love to see the results...

    Did Acer ask you to pimp this system? It's the second time you've linked to it in this post.
  • T2k - Thursday, March 4, 2010 - link

    Or perhaps simply because I THINK IT IS A GREAT DEAL and I want people to know about it?

    Stupid moron.
