Re: Youtube throttled by TWC? Core2Duos still cut it if you have a halfway decent GPU and a tuned up machine. Unless it's a very low end Core2Duo or one meant for a netbook/ultrabook it shouldn't have a problem handling a couple hundred megabits flying in, provided some time has been spent to reduce the amount of interrupts to the CPU and other processing overhead that causes smaller amounts of traffic to peg the CPU. The YouTube player on busy 1080p videos can consume 2% of a Core2Quad or 8% of a Core2Duo or less if you set up Stagevideo on a halfway decent GPU.
My desktop is a custom built machine I pieced together myself. i7-920 overclocked to 4.2Ghz, 16GB RAM (no swap) and 3-way SLi and it's used for gaming, general use and distributed computing projects. 1080p videos are almost completely decoded on the GPUs, and Flash sits there consuming no more than 2% of the total CPU time during 1080p video playback. Original will consume a CPU core but the GPUs will handle that without a problem.
My work computer runs a 2.53Ghz Core2Duo, and this machine is attached to a Gigabit port. Downloading at Gigabit speeds will peg the CPU at 100% and grind the hard disks down but YouTube will still play at 30FPS since the GPU is halfway decent and I've spent some time optimizing the machine. I may rebuild this machine to i5/i7, depending on what is laying around but it handles it just fine.
I'm not sure why your Core2Duo machine would load videos slowly though. Seems like something it should handle without a problem. |

| Also if the user is using HTML5 video player he/she will need a 8core+ system to run 1080p smoothly.
My laptop is 2.7GHz Core2 6MB L2 overclocked from 2.5GHz 4GB ram windows 7HP only using a IGP but it's only 1200 x 800 14" screen
In general Wifi cards use more resources then regular NIc's |

My laptop is 2.7GHz Core2 6MB L2 overclocked from 2.5GHz 4GB ram windows 7HP only using a IGP but it's only 1200 x 800 14" screen HTML5 is where I can see the exception here. Yeah, video acceleration for the players need some work still. 1080p should work fine on a 3-core CPU though, assuming one CPU is busy with handling network overhead and the OS, and the other two cores are taking care of decoding the video. 8 cores sounds like what would happen with the Original format.
Which IGP does your laptop have? If it's an Intel 4500MHD (GM45/x4500) or newer, an ATi Mobility Radeon HD 4 series or higher, or a GeForce 8M series or higher, those cards can do H.264 decoding and can almost completely eliminate the CPU usage from Flash. Make sure Hardware Acceleration is on within Flash, you have the latest GPU drivers from the manufacturer of the GPU (not the PC maker unless it's dual/switchable graphics) and enable Stagevideo if YouTube's player won't turn it on using a userscript. Won't help too much with the HTML5 players though, those still need CPU.
The older GPUs such as x3100s from Intel, NVIDIA GeForce 7 series and ATi Radeon HD 3 series and older, while they can do some H.264 acceleration and other methods of accelerating HD video, they aren't quite as effective. |

| Ah, ok. The 965 won't get you too far with acceleration of video. Pretty basic card. The GeForce cards however should be able to take the heavy workloads off of the CPU, no problem.
With YouTube try &wmode=direct in the URL which turns on Stagevideo if you've got updated Flash and drivers. The YousableTubeFix Greasemoneky script, which is one I use can also force it on if it can even be done. |

1 edit | Ah, ok. So you're speaking of the chipset and not the GPU itself.
I've attached a screenshot of what StageVideo does. This video's in 720p running on one of our desktop which runs Windows Vista and an Intel Q6600 as the CPU with a Radeon HD 5770 as the GPU. There are other YouTube videos loaded in the background, but there's my CPU usage during playback. |

according the intel's documents it's x3100 IGP controller. |

1 edit | reply to Smith6612 75% to 80% CPU usage when Forced full CPU speed & overclocked to 2.7GHz T9300 and with the &wmode=direct tag used
70% to 85% tag not used when load and playing
the CPU usage did drop to 65% when it was done downloading
usage on the 9600m GS was 40% no tag (2.53 P8700)
Something I noticed is SOME computers have issues with buffering. no matter what the specs of the computer |
