My next pc will be an Ivy Bridge. My current computer has an i7 950. I will probably use the on chip graphics as it will be used almost entirely for the web and watching digital and internet content.

IVB dual core is 55W. The current SNB QC is 95W, DC is 65W.

So the i3 31xx will be 55w TDP?

Yup, IVB DC (Core i3-31xx) is 55W, 10W lower than SNB DC (Core i3-21xx).

Do you think that reflects a significant drop in the actual power draw when performing similar tasks, or only at the top limit? If you're just streaming an internet video or something else simple, how much of a drop in power would you expect to see?

I am not sure, but I feel it is reasonable to expect, say, 5W-10W lower power consumption at idle and video playback because of 22nm process and improved design. Clarkdale -> SNB reduced the power consumption by 5W at idle, 10W at video playback, 15W at CPU + GPU load.

Meanwhile, we have a SB i3 that's already as powerful as a C2Q Q9400. We'll probably end up with a IVB i3 that's the equal of a i7-880.

I doubt if anyone knows the full answer to that question at this point.

But using history as a guide, my experience has been that when new CPUs come out that nominally work with the physical form factor of exisiting motherboards, the reality usually is that new chipsets optimized for the new CPUs also come out that work much better than the chipsets that were designed for earlier generation chips. Among other things, the old chipsets often don't support some of the new features of the new CPUs.

And then, typically, more advanced CPUs in the new family come out that won't work with the old chipsets at all.

So my total guess would be that the early IVB may work with current motherboards, but it will probably become apparent quickly that you're better off with a new motherboard.

And we'll have to start paying attention to mobo/cpu compatibility charts again, something we haven't had to do too much recently.

The release of the desktop version of IVB is still far away, in March-April, 2012. Until then there are not much to talk about, except for rumors, gossips and a little leaked information.

IVB will work with the current 6 series chipset mb with BIOS update (and SNB with 7 series chipset mb), that's what Intel guarantees (unofficially), for example in this slide:

Note, however, that the 24p issue is actually in the chipset and not the CPU, so to take full advantage of the HTPC improvements, you should get a 7 series chipset.

And this is probably the best reason (along with "series 7 will work much better with IVB than series 6") to upgrade.

Not sure, but it seems that the series 7 chipset will come along before IVB? Ive noticed that series 7 driver updates are already available on intel.com, which surprised me.

Can't find where I read it, but I heard february is when the 7 series chipset mobos should start showing up, or at least be announced.

Can always run your SNB CPU on it until IVB hits.
Its also possible that the 7-series that you see referenced now is for Socket 2011 (SNB-E), which supposedly should be released sometime soon as well.

I first saw the "hardware" theory in AnandTech:

Quote:


The limitation is entirely in hardware, particularly in what’s supported by the 5-series PCH (remember that display output is routed from the processor’s GPU to the video outputs via the PCH). One side effect of trying to maintain Intel’s aggressive tick-tock release cadence is there’s a lot of design reuse. While Sandy Bridge was a significant architectural redesign, the risk was mitigated by reusing much of the 5-series PCH design. As a result, the hardware limitation that prevented a 23.976Hz refresh rate made its way into the 6-series PCH before Intel discovered the root cause.

Intel had enough time to go in and fix the problem in the 6-series chipsets, however doing so would put the chipset schedule at risk given that fixing the problem requires a non-trivial amount of work to correct. Not wanting to introduce more risk into an already risky project (brand new out of order architecture, first on-die GPU, new GPU architecture, first integrated PLL), Intel chose to not address it this round, which is why we still have the problem today.

Now all of a sudden 23Hz = 23.973Hz was achieved instead of 23Hz = 24.000Hz by a simple driver update (not close enough, but a frame drop every 5 min is much better than a frame repeat every 40 sec). So I don't trust entirely what Intel says.

SNB-E will be released in mid-November (14th?). X79 chipset is not included in "7 Series" (very different).

Its a fact that the hardware clock is not accurate enough to reach 23.976. It may have been a decision to do a nearly perfect 24.000 instead of an inaccurate 23.973 - or it was just a driver bug on top of the hardware issue.

For me, 23.973 is still unacceptable - assuming i wouldn't use ReClock to fix it.
I would however prefer to not require ReClock, because it adds a few issues of its own.

Sandy Bridge-E processors and X79 chipset (Patsburg) will be released on November 14. This is the successor to the current Core i7-9xx LGA1366 processors (Bloomfield) and X58 (Tylersburg)/ICH10R chipset. Lineup:

- Core i7 3960X Extreme Edition 6C/12T, 3.3/3.9GHz, L3 15MB, 130W, $999
- Core i7 3930K 6C/12T, 3.2/3.8GHz, L3 12MB, 130W, $583
- Core i7 3920 4C/8T, 3.6/3.9GHz, L3 10MB, 130W, $294 (release date unknown)

Specs ([...] are those of LGA 1366):

- LGA 2011 [LGA 1366]
- Up to 6C/12T [6C/12T]
- PCI Express 2.0 40 lanes from the chip [0 lanes]
- PCI Express 2.0 8 lanes from the chipset [38 lanes]
- 4ch DDR3-1600, 1 DIMM per channel [3ch DDR3-1066, 2 DIMM per channel]
- DMI 2.0 between the chip and the chipset [QPI]
- SATA 3/6 Gbps: 2/4 [0/6]
- No USB 3.0 [No]

The specs were somewhat lowered from the original plan.

Actual product

Original plan

Notably

- No PCI Express 3.0 graphics
- No PCI Express 2.0 x4 connection between SNB-E and X79, that resulted in only 2 SATA 6Gbps ports

BTW AMD Southern Islands (HD 7000 series; Q1 2012) and NVIDIA Kepler (GK104; Q2 2012) will support PCI Express 3.0, as well as IVB.

Does anyone know what the actual difference between those CPUs is that warrants the extra $400?
It can't only be 100Mhz and 3 MB of cache that make up the difference, can it?

The first one is Extreme. That's got to be worth at least $150, the clock and cache make up the difference.

There was never value for the extreme edition parts. They are always the highest clocked parts and their dies were on the top bin, allowing them to overclock higher.
Some people want the fastest, no matter the cost, they buy an extreme edition CPU. People who want/need the absolute best for desktop, buy the workstation versions (dual socket).

On another issue I've released a new version of the decoder that solves ffdshow's occasional crash on h264 streams.

I tried installing 2509 last night. It wouldn't do any other resolution than 1024x768 @ 60Hz.

I have a i3-2100 in my main HTPC with an ASUS P8H61-M, 64GB SSD and 4GB RAM. When I am watching live TV via a Happauge TV tuner (clearQAM) in Windows Media Center I see some strange artifacts that look like dropped frames and interlacing artifacts, in both HD and SD. I notice what looks like frame dropping especially for instance during football games. Sometimes it'll suddenly look like you're watching film. Side-to-side pans show a lot of horizontal lines sometimes, especially when the show switches between shots/camera angles. In SD, the interlacing artifacts are very bad.

I don't see this behavior watching movies in WMC, either DVD or Blu-ray rips (MKV/H.264).

Any ideas?

FWIW, I also installed ONLY the graphics driver (gotta be safer than updating a BIOS, right? :-) ).

So far no issues - I already had BIOS 125 on the machine, chose not to update it at the same time.

Im running at 1920x1080 on a 22" Samsung monitor. I have a Intel DH67-CF running Win7 x64 SP1 with 8 GB RAM.

I wonder what the difference is between that 2509 graphics driver and this 2509 graphics driver that I've been using for a month and a half: http://downloadcenter.intel.com/Deta...=%0ADrivers%0A
Don't ask me why the graphics drivers aren't consistent when you search for an Intel branded motherboard or if you search for Graphics -> Processor Graphics -> 2nd Gen Intel Core Processors with HD Graphics 3000/2000.

Bazinga!

There's no difference. It's the same driver.

OK, I took the plunge to BIOS 0132 (from 0125) on my DH67CF using EB.EXE.

I experienced an issue that fooled me into thinking I had bricked it.

When the machine shutdown to do the update, I had no video during the update. The power light blinked for a while, and then went solid. I assume the update happened during this time, but no video.

After the update, the machine booted up, but no video during post. When Win7 got control, video came on and all was well.

To fix it, I put the configuration jumper onto the other pins. that gave me video during post. now that I had video for bios manipulation, I loaded bios defaults.

It turns out that if you change something under the video menuitem in the bios, you dont get video during post. I dont know which specific option, havent had time to figure it out ==> thats a job for Intel :-)

Anyway hope this helps someone else...

I finally upgraded my DH67BL to BIOS 0132 from 0131 earlier today. The upgrade went smoothly, and everything seems to be running OK. I'm not sure if there really is a change between 0131 and 0132, other than hopefully fixing the installation problems (bricking) that some people had with 0131.

Bazinga!

how can i get a quick sync accelerated version of FFmpeg.

I use serviio dlna server, which uses FFmpeg.

I would like quick sync acceleration for the transcode.

Is there any possibility of quick sync support in FFmpeg?
