Intel Atom vs. VIA Nano

Intel Atom vs. VIA Nano

Introduction

When we think of the CPU in our systems today, we think of high powered Core 2 processors or a cheaper Phenom in order to power our gaming systems of the day. These two processors are fighting it out for the top of the performance ladder and a battle it has become.

While we concentrate on this sector, the focus is now moving towards the lower end of the spectrum. VIA has really cornered this market in the past when it came to ultra compact PCs; EPIA has been VIA’s biggest success and with the evolution of the VIA processors, each generation has gotten just that little bit more capable. Now Intel has seen just how popular this is, we finally have some competition in this sector.

Until recently the C7 processor defined performance at lower power consumption, but not to be outdone, Intel released at Computex 2008 its introduction to take on VIA; the Atom series processor. However, VIA wasn’t going to let Intel win here, and at the same time announced its latest update to its processor range; the Nano.

Today we will be pitting the Atom platform against the Nano platform. Who has the best performance and energy savings? – Well, we don’t know yet, but by the end of this we will have an informative answer to that. Let’s move on and check out the platforms individually before we get into the testing phase.

The Battle of Mini-ITX Platforms

The Intel Atom and VIA Nano processors have been making a ton of noise in the market place as they are inexpensive, energy efficient and fit into sleek and sexy devices that consumers are looking for today. The day the VIA Nano processor was announced I was actually at Centaur Technologies down in Austin, Texas meeting with Gleen Henry where I got to see some Nano processors being produced right before my eyes. I had to wait nearly a month to get a VIA reference board in my hands with a VIA Nano processor, but it has been worth the wait. Since I have already covered the basics and introduced the Nano processor in my Centaur Technologies Tour article we will jump straight into things.

Armed with the VIA Nano processor and the Intel Atom processor, I can now do a direct performance comparison against two of the most talked about processors for 2008. The VIA Nano reference platform we were sent isn't a retail product, so keep that in mind while reading the rest of the article. The Intel Atom was tested on the D945GCLF, which is a retail product you can purchase today for $66 plus shipping.

These two platforms might both be using Mini-ITX motherboards, but the features do differ between the very different processors. The VIA Nano processor is built using 65nm process technology (the Atom uses 45nm) and it's major claim to fame is the 64-bit Superscalar Speculative Out-Of-Order MicroArchitecture. Will this be enough to keep the Intel Atom processor at bay? Let's take a look a closer look at the test systems and find out which one is faster in the benchmarks!

VIA Nano Processor for Servers: Efficiently Hosting the Cloud

VIA Nano Processor for Servers: Efficiently Hosting the Cloud As the Internet and its software cloud continues to grow and evolve so does the demand for data centers, web hosting farms and dedicated hosting services. Today's data centers are seeking alternatives to traditional multi-core 1U rackmount server solutions, with particular focus on reducing TOC and environmental impact. Generational leaps of the last few years have lead to the widespread adoption of high performance multi-core processors in many traditional server applications.

XPS All in one desktops

Pros: This is the coolest computer I have ever had. I wanted a touch screen but they were too expensive but this is perfect! I love everything about it. The screen is very clear and bright. I like having the touch buttons on the side.

Cons: The top gets hot the longer it is on but that has not been a big deal. It is very heavy so make sure it is on something stable.

Review: I love this computer! The usb ports are on the side and very easy to get to. I love the wireless keyboard and mouse!

Dell Inspiron 13 Review

Pros: This PC runs very well (You need 2GB to run Vista Smoothly). The screen quality is very vivid, with the HD screen. The Navigational tools at the top of screen with the Vista programming clears up a lot of clutter as you load your PC. Also, the fan does very well in cooling the system and the PC is extremely quiet.

Cons: The PC is a very dark blue, almost a black, but that does not bother me (just a heads up). Also, there is only two USB ports and oil will show up slightly on the palm rest.

Review: The oil on the palm rest is easily remedied with a simple cloth. And for ten dollars you can by a USB hub that will allow you to use at least 5 USB ports (These hubs are quite portable now). All in all, this is a great deal.
