So IDF is on full swing...and they talked about sandy bridge...
Anandtech is following it and heres the recap...
Dadi mentioned that Sandy Bridge has around a billion transistors and that in 10 - 11 years we’ll have chips with 100 billion transistors.
Sandy Bridge brings Intel’s integrated graphics on die as we’ve already mentioned. Now both the GPU and CPU can share the L3 cache, which Dadi indicated resulted in a 4 - 5x increase in GPU performance for data in the cache.
Dadi confirmed that Sandy Bridge would use a high bandwidth ring bus to connect the CPU, GPU and other on-die components to one another.
We also got confirmation that Sandy Bridge will support both CPU and GPU turbo modes.
Officially Sandy Bridge will be called the 2nd generation Intel Core processor, and here are the new logos:
Intel confirmed that Sandy Bridge has dedicated video transcode hardware that it demoed during the keynote. The demo used Cyberlink’s Media Espresso to convert a ~1 minute long 30Mbps 1080p HD video clip to an iPhone compatible format. On Sandy Bridge the conversion finished in a matter of a few seconds (< 10 seconds by my watch).
Dedicated hardware video transcode is Intel’s way of fending off the advance of GPU compute into the consumer market, particularly necessary since you can’t do any compute on Intel’s HD graphics (even on Sandy Bridge).
Given Intel’s close relationship with the software vendors, I suspect we’ll see a lot of software support for this engine when Sandy Bridge ships early next year.
And some features and stuff...
Naming of the new processor family
List of processors
The new LGA 1155 SOcket
The CPUs will require a new socket (LGA-1155) and all new motherboards based on Intel’s forthcoming 6-series chipsets.
The chipset brings 6Gbps SATA support (2 ports) but no native USB 3, motherboard manufacturers will still have to use an off-chip controller to get USB 3 support. Intel will also enable 5GT/s PCIe 2.0 slots with its 6-series chipsets.
And also the on board video transcoder...it decodes and encode video very fast...
And also the new turbo......which also support the gpu onboard...
Both CPU and GPU turbo can work in tandem. Workloads that are more GPU bound running on SNB can result in the CPU cores clocking down and the GPU clocking up, while CPU bound tasks can drop the GPU frequency and increase CPU frequency.And the bad thing...
The whole roadmap
There's no new information on Sandy Bridge overclocking at this point (although it's looking increasingly likely that there will be a reasonably priced K-series SKU for those users who want the flexibility to overclock without spending $1000). I've included the overclocking text and roadmap from our Sandy Bridge Preview below if you're interested in seeing what Intel has planned.
The K-series SKUs, these will be more important with Sandy Bridge
With Sandy Bridge, Intel integrated the clock generator, usually present on the motherboard, onto the 6-series chipset die. While BCLK is adjustable on current Core iX processors, with Sandy Bridge it’s mostly locked at 100MHz. There will be some wiggle room as far as I can tell, but it’s not going to be much. Overclocking, as we know it, is dead.
Intel makes three concessions.
First and foremost we have the K-series parts. These will be fully unlocked, supporting multipliers up to 57x. Sandy Bridge should have more attractive K SKUs than what we’ve seen to date. The Core i7 2600 and 2500 will both be available as a K-edition. The former should be priced around $562 and the latter at $205 if we go off of current pricing.
Secondly, some regular Sandy Bridge processors will have partially unlocked multipliers. The idea is that you take your highest turbo multiplier, add a few more bins on top of that, and that’ll be your maximum multiplier. It gives some overclocking headroom, but not limitless. Intel is still working out the details for how far you can go with these partially unlocked parts, but I’ve chimed in with my opinion and hopefully we’ll see something reasonable come from the company. I am hopeful that these partially unlocked parts will have enough multipliers available to make for decent overclocks.
Finally, if you focus on multiplier-only overclocking you lose the ability to increase memory bandwidth as you increase CPU clock speed. The faster your CPU, the more data it needs and thus the faster your memory subsystem needs to be in order to scale well. As a result, on P67 motherboards you’ll be able to adjust your memory ratios to support up to DDR3-2133.
====================================================================and also we hear about Ivy Bridge also...
Earlier in the keynote, we heard that Ivy Bridge is making its way through the fabs now with production scheduled for 2H 2011
