| Any ideas about how long before USB 3 on Dell? I'd like to purchase a new Dell, possibly a laptop, maybe also a desktop. I'm interested in USB 3, and am wondering if anyone has an idea about when the big pre-built makers (Dell, HP, Gateway, Acer, etc) will be releasing USB 3 models?

Considering that USB still has such heavy CPU dependence (especially compared to firewire), I can only imagine how much CPU overhead USB 3 and proper USB3 devices would have.

it may have mattered with single core but not really any more |

At one time I held out great hope for firewire. I ordered it on all our PC's. It's never been used. ESATA has been used, HDMI, USB, but not firewire. If USB 3 becomes available I'm 100% certain it will be used by members of my family. If terrabit firewire comes along I'm 99% certain nobody in my family will ever use it.

With firewire, getting close to (if not reaching) the advertised throughput was no problem, since its I/O was handled by the hardware at each end of the connection (a lot like SCSI).

Intel's chipset roadmap doesn't show USB3 until 2011. |

I use it for a video camera and my external optical drives. For the latter, I actually had problems with USB -- it was occasionally bluescreening my PC when I was ripping DVDs.

looks like your wrong highest it got was 6% and speeds look great
what was that again? |

Davenport, FL | It's a well known fact that USB 1.* and 2.0 are software-dependent for I/O operations (meaning, they ride the CPU) vs. hardware-based I/O like in Firewire.

kudos:1 | It's also a well-known fact that a bit of CPU usage really isn't a big deal these days. Maybe those few % it would matter slightly if you're running something else that's using your whole CPU like encoding or simulations, but the vast majority aren't doing that and even if you are the usage is slight.
Same goes for integrated audio. This isn't 2002 anymore a bit of audio processing doesn't use a significant amount of a modern CPU.
The only people who care are purists who care on some sort of ideological level rather than a practical one. Most people care about results: can I plug most things into it and will it go fast. USB is way ahead on the first one and also the second one when USB3 hits. Most people's CPUs are sitting idle most of the time anyways. Actually it makes sense to use the CPU and make the other hardware cheaper. |

the 6% i saw was for just random screen shot of the benchmark lol
uploaded there screen shots
note CPU usage is ZERO
zero CPU usage and 100MB/s Read/writes on an external drive seems win/win to me |

| A 0% CPU usage is a tad suspicious. Yes, one possibility is a usage under 1% (or more precisely, under 0.5%), but the other one is that the program can't measure it accurately. 
I don't know much about the finer details of USB 3, but even assuming some serious HW assist, I'd still expect to see *some* CPU usage.

1 edit | well seeing as 2 different aps are showing 0 my guess is its under 1% also the testing was on an i7 and thats usage over all 8 threads
so it could easily be 1% on one core
point still is CPU use is extremely low |
|
| I'm not convinced since there's barely any evidence.
