The Sandy Bridge Preview
by Anand Lal Shimpi on August 27, 2010 2:38 PM ESTThe Roadmap & Pricing
I’ve defined the launch parts earlier in this article, but now I’m going to put them in perspective. When Intel provides its partners with roadmaps it also provides them with an idea of where future CPUs slot into various segments/price points. For example, Intel’s LGA-1366 roadmap tell us that in the “Extreme” market segment Intel only has a single product offering: the Core i7 980X. And in Q1 2011 the 980X gets replaced by the 990X.
Usually based on this information you can get a general idea of how much future products will cost - or at least what they will be comparable to. In this example the 990X will most likely be priced at whatever the 980X is priced at. Products may change, but the price people are willing to pay in a certain market segment usually doesn’t.
What we have below is the Intel roadmap, with Sandy Bridge included, for Q3 2010 through Q3 2011. The further out you go in a roadmap the lower your accuracy becomes, so I wouldn’t worry too much about us not seeing LGA-2011 on there yet.
It’s based on this roadmap that I mentioned some pricing earlier. If all stays the same, the Core i7 2600K will take the place of the Core i7 950, currently priced at $562. The 2600 will fit somewhere around the 680 and 875K ($342) and the 2500K will replace the i5 760/655K ($205 - $216).
The cheapest Sandy Bridge at launch will be the Core i3 2100, which will replace the i3 560 at around $138.
Now pricing is always a huge variable, but I have to say, based on the performance you’re about to see - these parts would be priced right.

Why not comparing with a HD 5570? That is what Llano is supposed to have, Redwood-class IGP. An HD 5450 is quite pointless. It just reflects competition for Ontario. But Sandy Bridge is not Ontario's competition.And what about image quality or GPGPU support? Pure FPS numbers are only half of the truth.

dont think so, its said that AMD's Fusion built-in GPU will have 400 SPUs (HD 5670 level-graphics), thats a far cry from HD 5450's 80 SPUs ;)so if you wanna game you still have to use something from a real graphics manufacture like AMD when it comes to GPUs bult into CPUs, as a added bonus you also have updated drivers and a decade old DirectX 9 compatibility, so you old games work without any big problems

I am impressed that you have a functioning sample at least four months before it's available, run it through enough paces for a review like this, and they let you release the numbers. I mean, are they trying to suppress holiday sales?When do you think you'll have a Bulldozer sample from AMD to run a similar preview? Barring a surprise from AMD, at this point, it looks like I'll be building an i7 2600 early next year. The similar spec chip from today is an i7-975 Extreme, which is the fastest quad core in the bench, and Sandy Bridge runs 13-14% faster in the only benchmark I care about (x264). I guess even that might change significantly if it can take advantage of this "alleged on-die video transcode engine." I'd not heard of that before.

Honestly we're probably several months out from having Bulldozer silicon in a similar state. With the past few generations of Intel CPUs, by around 4 - 6 months before launch we're usually able to get access to them and they perform very well.With AMD the lead time is far shorter. I don't expect us to have access to Bulldozer silicon that's worth benchmarking until Q2 2011 at the earliest. I'm more than happy to be proven wrong though :-P

I guess I'm mostly surprised that Intel would do it. Conroe made sense. They had to show the world as early as possible that they had something significantly faster than AMD, suppressing sales of that for their own a little later. But now that they own that performance crown, why show previews so many months early? I suppose I could be over-analyzing it and the vast majority of the market couldn't care less so it makes little difference to their bottom line. Bragging rights simply make for good PR.Sad to see Bulldozer so far out. I assume the server chips will ship before the consumer ones, too, so it'll be at least a solid year before it could be in my hands, anyway. Oh well. To be honest, my C2D E6400 still does well enough for me. Maybe I'll just make my upgrade an Intel G3 SSD. If I got both that and SB, I don't know what I'd do with myself.
Thanks, and keep up the good work.

This preview wasn't Intel sanctioned, I believe Intel will release its own numbers at IDF in a few weeks.Take care,
Anand

Oh, I had assumed you got this chip from Intel and they had a typical NDA that said when you could talk about what you found. Where'd it come from, then? One of Intel's motherboard partners with whom you have a friendly relationship?aegisofrime - Saturday, August 28, 2010 - link
I must say, I'm really grateful for this article. I'm in the middle of planning an upgrade and information like this is really valuable to me. (and I guess to a lot of people as well!) I would just like you to know that your articles actually do influence some of our buying choices. So... Thank you! :DNow, all I need is a Bulldozer preview and all the pieces are in place...

few things clear and few unclear as of nowthis sandy bridge review sample here do not have TURBO enabled. The CPU runs at 3.1GHz all the time, regardless of workload as anand stated
it says "Both the CPU and GPU on SB will be able to turbo independently of one another. If you’re playing a game that uses more GPU than CPU, the CPU may run at stock speed (or lower) and the GPU can use the additional thermal headroom to clock up. The same applies in reverse if you’re running something computationally intensive."
QUESTIONS
Q} will the on die GPU unit work in tandem with the other discrete GPUs out there or it will shut off? if yes will it work when sli or crossfire is enabled :p
Q} whatever the above statement says will it happen if we use discrete graphics from nvidia or ati?
Q} will there be any possibility to disable ONLY GPU and in certain cases ONLY its TURBO FEATURE
Q} any possibility to remain the GPU overclocked the whole time when cpu is IDLE
Q} what about accelerated hd video playback using the on die gpu?
Q} it support VT-x and AVX is it possible for you anand to use specific benchmark for these instructions, same request goes for the AMD
Q} as someone asked will there be a cheap 6 => core processor for mainstream market
Q} again as per the last comment ......When do you think you'll have a Bulldozer sample from AMD to run a similar preview?
this Ques Must be answered
all n all what i think even if there is a 15-19% perf. Jump its not worh the spending when u consider u have to upgrade the entire platform
and moreover limiting Overclocking features damm! a retarded decision i am not in a mood for amd but if the overclocking hits then i will move 10000...% :angry:

If you're asking about an SLI/CFX pairing with the IGP almost certainly not. The only company to ever attempt something like that has been Lucid with the Hydra chip and the results have been less than impressive. Architecturally I don't know that it'd even be possible for them to try with the on die GPU. The Hydra chip sat between the CPU and the Gfx cards on the PCIe bus and looked like a single card to the OS. There's no way for them to insert themselves into the middle of the connection to the IGP.
