Hi, I guess you're high on crystal meth or something like that. I still doubt. I don't know what the HELL this racism related to this chipset. Or you want people to HATE Intel. No matter how much Intel pay you to simply justify their worst designs, but they simply can't hide the truth. It could be really logical and innovative if Intel used such chipsets as microcontrollers instead of laptop processors. They could have made some awesome appliances, but still Intel decided to make a fool out of their consumers by using these for sub computers. If the design is terrible, at least accept it rather than making fool
Now if someone Told You he was Middle Eastern or Iraqi or Egyptian You'd Believe it. In his Younger Days You Wouldn't.
Jobs isn't Syrian. NOW he Looks Middle Eastern but His Younger Days He was Clearly Bulgarian / Russian.
Dear one, I've used a netbook with atom n270 chipset and just want to say how frustrating was my experience. I don't know what's good about this "Diamondville" architecture. Let's compare this to some other low powered processors: Even the lower end Qualcomm snapdragon 450 can handle full HD videos flawlessly. They are cheaper as well. They also offer adreno graphics, good enough to play moderate games at low to medium settings. At the other side, this n270 chipset comes with underclocked Intel gma 900 series, which is completely useless. Let's get a step more ahead. I've also used Mediatek Helio P60 phone which I purchased for Rs11000, or 120GBP approx. This chipset is built with 12nm process. Believe it or not, this chipset is really powerful enough to render intensive games such as Asphalt 9 at high settings.
I'm Happy - The Way I am - Your a PIG - Looking for a Difference to Feel Superior. You're Inferior PIG brained Scum.
And I'm not Black - My Legs and Arms are An Orangey / Very Very Light Brown Color. My Face is Darker - It Takes more of a Bashing and Has to Deal with more Bugs in the Open. My Feet are Whiter Than Yours.
Your Down Syndrome B1tch and Ba5tard don't behave Like You Do They? - Why do you Claim they're Yours? Their Medical Condition is down to You and So Is Mine. My Mother didn't go to School as Pakistan was being Attacked by Eastern European Spies. It's the Reason Eastern Europe is gonna be Terminated.
This Sister F*cking Vermin PIG from Another Galaxy is Here Claiming Earth. Your Wearing Human Clothes and that Makes You Human? - No it Don't. If Someone Killed your Brother and then Did Plastic Surgery to Look Like Him, Would they be Him? If You See a Mirage Does that Mean there is Water There? I don't Look like Mosche - No I don't - He Looks Like Newton - I look like My Grand Mother. My Skin Color - That's Down to Where I'm Living. I don't have the Natural Immunity to Bugs here. If Your Brother Went to Melbourne and Darkened -Would they Not then Be your Brother? Does Brian Krzanich - Look Like You. You go to America and Claim You're their Brothers. In Reality your Not Since You're PIGs. Even If you Stayed there and Your Color Darkened, you still wouldn't be according to your Standards. You're a PIG.
My Subconscious Mind Just Clicked - "make better toys such as RC helicopters." - Tell Intel to Come and Get You in a Stealth Plane So We Can Steal It. No PIG, I'm Not Gonna Drive My Dick to The Hole as Your Saying. 60 Million People in Ukraine are gonna be Dismissed. 2 Billion Slavs in Serbia, Bulgaria, Greece, Romania, Russia, North USA, Canada, Latin America, India, North Korea, France, Spain and Portugal are gonna be Dismissed.
There's Cheaper Alternatives if you can sacrifice Power Efficient. A Core i3 is Not too Expensive.
You want 720p and Photo Editing - You Need Intel® Core™ m3-7Y30 Processor. It Costs a Lot More and Still is Very Power Efficient.
I didn't Say it Could do 720p, Did I? The N270 is Cheap and Power Efficient. Before you go on about Low Powered Arm - They cant Run something like Windows XP. The Low Powered ARM run Android 2.2 - Not much more than Symbian S60. To Run Android 4 - You need More Power Hungry ARM's. To Run Android 7 You Need Faster more Expensive ARM's - 45nm Manufacturing Process. They Cost More. What is N270 - Cheap - Can Run Windows XP and Not too Bad for Power - Relative as its running XP.
Hi, This is the most annoying piece of junk I've come across. It's really obvious that if you find any device with Intel atom N270 CPU, this will be a strong reason why not to buy this device. Here's why I hate this most : 1. It is so incredibly underpowered. 2. It can't even render 720 p resolution, even if it does it's far from being watchable. 3. Even a descent size image loads up in more than 15 seconds. Again it is I'm possible to run any photo editing. 4. It can't handle any more than 1 task as the performance falls drastically making it useless. 5. Overall architecture of this is based only on cost cutting with worst possible performance efficiency. 6. This is so incompetent that it can't be even used as a lower level smartphone processor. 7. All the models offering this crap comes soldered to their motherboards making no room to upgrade. This guarantees your total waste of money. Honestly, I can't even list any more reasons as I hate everything about this chipset. There is literally NOTHING which it can handle, not even basic computing. Suggestion to Intel: It's good to diversify your business from microprocessors to toys like this, but at least, you can make better toys such as RC helicopters, etc as they are faster and better value for money. Please don't waste your research to downgrade your existing technologies to such an extent, that it becomes completely useless.
The N270 is good enough for Windows. After things are loaded into RAM from the Slow SSD the processor does a good job. I remember running Windows on a 350 MHz Pentium 2. I had to upgrade to a 450MHz Pentum 3 to run DivX movies. The N270 is equivalent to 800 MHz. Linux needs a 500 MHz processor (Light Distribution - XFCE) or a 1 GHz for a KDE environment. Windows is more feature rich than KDE. Supporting more devices and background services such as Anti Virus.
