Terrible performance because it's so old


3 years ago.

It powers my daily driver - a Fujitsu Lifebook E780 laptop from 2010. Works flawlessly paired with an SSD and 8 GB of RAM, but I could use more cores for multitasking. That said, it handles like a champ Office 365 work with Bitdefender antivirus in the background, Google Chrome with multiple tabs open as well as several apps open and docked in the Taskbar. Multiple desktops also. It shows its age when trying to watch Youtube or listen to music while torrenting (audio lags and stutters). I've played games up to Assassin's Creed Black Flag, but nothing newer because of the GPU (Nvidia Geforce 330M). What's frustrating is the fact that, while craving more speed and performance, I realize this 10-year old CPU covers my productivity needs most of the time. Upgrading would be done on a whim, not out of necessity.

pretty nice for an old processor


4 months ago.

In 2020 I bought Panasonic CF-C1 with this cpu. After upgrading hdd to ssd, it works like a champ with Mint Mate. Web pages, youtube, docker, libreoffice - you name it. And yes, it runs windows 10 (I dual-boot it to watch netflix and amazon prime). The only thing that lags is windows update - it can take hours.

Still daily in use. Lives in my Thinkpad X201, 8GB, SSD (best portable calculating machine I'v ever touched). To be precise, I'm using it to write this comment while doing heavy calculations in the background. Sure, the keyboard gets a bit warm and it takes a bit longer...to be honest, I don't know if you can boot Windows 10 with it.

Esto es de una laptop del 2007 Y le gana a ese i 3 Que vale maas


4 years ago.

USA-User is probably referring to his/her mom. Old and bad performance. This is a 10 year old processor. It does everything as well as 10 years ago, like your granddad, that does his gardening work. Sure, there are faster machines. More efficient ones. But it is effective. It does work tasks and browsing. Great for office work. Really good battery performance. Almost vintage style, while still being useful. And: The chip costs less than Fallout 76 original price. It lags not as much as Fallout 76, it looks cool, it just works. 520m win - everyone else lose. 4 stars, because yeah, its old. There are alternatives sure. But if you have one, it is enough for serious office work. Dont expect a gaming or calculating prodigy, expect a solid processor.
