Common Myths that Laptop Agents Say

Sometimes it’s faulty understanding. Sometimes there is no understanding, and they’re just repeating what they’ve been told to say. Sometimes it’s willful misdirection in order to make a commission.

Here are some of the things we’ve heard while shopping for laptops that aren’t necessarily true. Many of the dell showroom in Chennai only sell Dell products but many franchising shops are not equally doing it.

…for a limited set of circumstances. The thing is, most programs tend not to take advantage of all four cores on a quad-core CPU. There are specific examples: video encoding, 3D rendering, scientific simulations, artificial benchmarks like counting Pi up to a million decimal places … but, realistically, after two cores you get diminishing returns for most consumer-level applications.

This is because an application has to be specially written so that it can send a workload to each individual core, which, depending on what the application is doing, may not be an easy thing to program. There are simply some tasks that are most efficient when running on a single core, rather than on four.

As such, this means that a dual-core chip clocked at 2.0GHz can, in many cases, outperform a quad-core chip clocked at 1.8GHz, simply because a program may only take advantage of two cores, and the dual-core chip is faster on a per-core basis. First know about the products completely. If you are about to buy a ThinkPad laptop first know about the Lenovo ThinkPad price.

There’s a sub-species of this particular furphy: “it’s quad-core 2.0GHz, meaning you get 8.0GHz of power”. It’s simply not true; you won’t magically get 8.0GHz of power in all circumstances to throw at anything you desire.

While there’s some code to help spread workload automatically across cores in the operating system, for the most part, they don’t just magically work in concert; applications need to be specifically coded to take advantage of them. Even then, some cores will only be partly loaded, and some will finish their workload before others. There are applications like Handbrake or 3DSMax that will happily load all of your cores to 100 percent — but if you’re using these programs, then you already know you need as much grunt and as many cores as you can get — if you don’t know what they are, you’ll likely do fine with a dual-core CPU.

Many programs still only use one core, limiting you, in this example, to a flat 2.0GHz of performance. So it is important that you look carefully before buying a laptop. The Lenovo showroom in Chennai is good only for Lenovo products so be aware that you get only Lenovo laptops.
