    Sandy Bridge?

    What realistic advantage do the currently-released Sandy Bridge processors have over the QPI i7s?

    Would the integrated graphics even be used when a GPU is installed?

    As far as I can tell, they're actually downgrades from the last-gen i7s, with only dual-channel RAM support and no QPI. It isn't actually listed whether they use DMI or QPI, or is it some new variation on DMI, considering that the chips are one pin short of 1156, which used DMI.

    So what extras (excluding buffed integrated graphics) will the next generation of apparently QPI- and triple channel RAM- less make them worth their money over the previous generation of processors?

    I cannot answer your questions as I do not know (the others here may know). But it seems like you are comparing the socket 1366 processors with the new 1155's, which is wrong. You need to compare the 1366 with the new socket 2011 processors that is the successor of the aforementioned. It's coming out later in this year, and it will feature quatro-channel RAM afaik.

    Indeed the new socket 1155 is the newer socket 1156. 1366 will be replaced by 2011 due out the end of the year.

    Also, to point out the Multi Channel RAM thing between the sockets in reference to comments in 1st post.

    Socket 1156: Single/Dual Channel

    Socket 1366: Single/Dual/Triple Channel

    Socket 1155 (Sandy Bridge): Single/Dual Channel

    Socket 2011 (Sandy Bridge-EN/EP/EX?): Single/Dual/Triple/Quad Channel? (Considering 1366 can support all up to Triple, I suspect this should be able to all up to Quad)

    Some Info on Sandy Bridge, and Socket 2011, as well as 1155.

    I know Wikipedia isn't an Accurate source, depending on the articles and who contributed to it...

    LGA 2011 - Wikipedia, the free encyclopedia

    Sandy Bridge (microarchitecture) - Wikipedia, the free encyclopedia

    on that second link, seeing the pricing for Socket 2011 CPU's, for the Desktop. I really hope that is NOT accurate, or that cheaper versions ($300 for starters would be acceptable) will be released for 2011, otherwise, Intel can kiss my @$$, and I'm heading back over to AMD's Camp again.

    Its bad enough there are no real current Socket 1156 Sub $100 CPU's, and to expect people that were able to procure $300 Quad cores for 1366 (me, and many others), to expect us to plop down $400 or more for a CPU for the replacement platform for 1366, if they don't wise up, they'll really start alienating their customer base like Nvidia has for the last year (Only "affordable" Fermi is the $75-80 GT 430 so far, thats really no better than the older GT 240), at least for us custom builders, maybe not so much for OEM's like Dell and HP.

    I've been away for a while..

    So there's a magical Socket 2011 that's going to come out in a year and knock my 1366 out? What new capabilities will this new series of processors have that my 950 doesn't, with my very nice 6950 Radeon? Does the graphics part of the Sandy Bridge architecture even get put to use with dedicated graphics? If so, then just for regular processing goodness?

    I'm not all 100% sure what the new Socket Provides, I do know it has some to do with the newer Sandy Bridge CPU's for that Socket, as well as Improvements for PCI Express controller on the CPU, and some other things like Quad Channel Memory.

    The Main thing about 2011 for me, is that I'm mainly pissed that Intel decided to change up its Ethusiasts Socket platform, which means if we want something better than we have already, its a complete system Overhaul, CPU, RAM, & Mobo.

    Supposedly from what I've read is it won't be out till later in the year, and its also supposed to Introduce PCI Express 3.0, which should be twice the Bandwidth of current 2.0.


    Myself, I'm still pretty content with Socket 1366, as I only have a 920, so there's some upgrade options for me, if I don't want to OC... I doubt I would come across a 6 core for cheap in the next year, would probably be a couple/few years from now before I'd be able to find a 6 core for less than $300.

    And my new GTX 470 just arrived yesterday (bought Open Box On Newegg for less than $193 after shipping, and aside from the box being opened up, the card was a Brand new Virgin Card, with all the accessories and documentation as well as the Free Game Scratch off Coupon Code), so that should hold me over at least until the Fall when Elder Scrolls V: Skyrim is released.

    I'm honestly not liking the way Intel is going with their Sandy Bridge series.

    How do you like your GTX470? That's a really good deal you got with that. I'm not sure even that kind of deal would've motivated me to buy an Open Box computer component, however. I just don't like the idea of buying "used" electronics.

    Open Box aren't used, their opened items. Sometimes all that you get is the item itself with no accessories or its a White Box Item (bare item).

    This GTX 470 from MSI, like my GTX 285 before it (also MSI), were both Brand spanking new "virgin" cards, with all of the accessories and Documentation, etc.

    Just that the box was opened. The ECS brand 512MB 8800GTS I bought a couple years back, that I sold to a friend a year and half ago, was also Open Box, and brand new never used as well.

    Same with my Current Socket 1366 Motherboard, only needed to obtain some new Plastic pins for the Chipset heatsink to secure it down (one was snapped), and it was good to go, all accessories. (Yes, MSI also LOL, the last 3 Motherboards I've had were all MSI's, 1st and 3rd were Open Box, 1st was a Socket 939 SLI board, just bare board, 2nd was a Socket 775 SLI board, Brand new, 3rd/current was Open Box)

    Anyways, the 470 even came with the Card with the Scratch off part to reveal a code to download 1 of 3 Full Games from MSI.

    So that was one more way to tell this thing was new as well.

    Basically got a Brand new card for way less than new.

    What was funny was the one I ordered showed the Street Fighter II Graphics on the sticker, the one I got was one of the newer models with the Fighter Jet on it.

    Oh well.


    Ran The Unigine Heaven 2.0 Benchmark and posted about it a day or so ago:

    http://www.techimo.com/forum/distrib...ml#post3214558

    Also ran the X3: Terran Conflict Rolling Demo (non playable), and was able to run fully maxed out in all settings at 1920x1080, and lowest frame rate I got was about 30 or so, there was one hiccup in one scene where it dropped to 15fps for a second or two, but bounced right back up to 30 or so. Had seen some parts where it was doing 70+.

    haven't ran 3D Mark yet, or too many other benches.

    But so far its doing pretty good.

    Only thing better than this right now is if my Mobo supported SLI (Crossfire only model), and could throw in a 2nd 470 LOL.

    Open Box Items I've bought that have all Worked.

    GTX 470

    GTX 285

    GT 220

    9600 GSO

    9600 GSO

    Radeon 4870

    Radeon 4870

    Radeon 4830

    9800GTX (Recertified)

    512MB G92 core 8800GTS

    MSI X58 Platinum Motherboad

    MSI Socket 939 Nforce 4 SLI motherboard

    MSI Socket 775 Intel P31 Motherboard

    I'm forgetting a few other items, but all of these were with in the last 2.5-3 years or so. (with exception for the Socket 939 board which was over 4 years ago)

    All of them worked fine, with no problems.

    Only time I've ever had bad luck with a part was a Recertied/Open Box Leadtek Brand Geforce 6800GT from Newegg YEARS ago, that was DOA, and returned, got a brand new MSI Geforce 6600GT instead, and used the remainder cash on some other stuff.

    Still have that 6600GT too

    but that 6800GT is the only flaky Item I've ever gotten via Open box or Recertified Items.

    Wink

    I don't think anything could negate the uneasy feelings I get when I think about ordering any electronic other than brand-spanking new.

    I'm impatiently waiting for that GTX560 to come out. I want to see how it compares to AMD's 69xx chips.

    It probably won't, thats the 570/580's territory, the 560 should be the replacement for the 460/465 cards, which compete with the 6870's range.

    Chances are, it will probably best the 6870, and come close to the 6950 or land somewhere in between, unless AMD comes out with a 6930 like they did with the 5800 series (5830).

    In order for NVIDIA to be competitive in this market segment, I image that the 560 is going to need to go head-to-head with the 6950. The price leaks indicate that the 560 is going to be $290-310. If those are right and the 560 is just more powerful than the 6870 and doesn't compete with the 6950, then why would anyone buy it?

    The 580 is in a class of its own at the moment, the 570 compares with the 6970, but NVIDIA doesn't have a chip that compares to the 6950. I can't see why NVIDIA wouldn't position it as a competitor to the 6950, to be honest.

    Seen some 560's at the 250 dollar mark, so its a good contender to best the 68xx, with a bit of an overclock should be close to the 6950. Cant realy say no to that price.

    560 TI easily matches a GTX 470, but with lesser specs, and less Power consumption and heat output.


    Nvidia GeForce GTX 560 Ti Review: GF114 Rises, GF100 Rides Off : The GeForce GTX 560 Ti Review


    and yes, could easily tie a 6870, as well as do a bit better.

    Nice thing is, FINALLY Nvidia has a GPU that can attain 900MHz Core Speed, even 1GHz with some high end OC models.

    ATI/AMD has had some cards with the 5000 and 6000 series with core clocks that high already, but Nvidia still playing it cool.

    I know its not as important as it is to have higher clocked shaders, but with Radeons the Shaders are locked to the core, but its still cool to have a Core that clocks beyond 900MHz and reaches 1GHz, seeing as CPU's attained that crown over 10 years ago.

    And The fact you don't need Liquid Nitrogen to cool the suckers too.

    Back to the topic, i don't think the 2011 sandy bridge processors will support quad channel i believe they are keeping with the tri-channel, the 1155 are dual because they wanted that chip to be cheap since it is a retail model.

    I remember reading a comparison sheet about the sandy bridge and it was only boasting a 7% increase compared to current i5 and i7 processors.

    Really, the sandy bridge isn't worth it since the Ivy Bridge is being talked about, the Ivy Bridge is suppose to be there enthusiast model that boasts a good 8 physical cores along with hyper-threading (mmm 16 cores) as well as the new turbo-boost and pci-e controller on the die just like the sandy bridge.

    But one release that i have my eyes on and theres rumor that it'll come out late next is is the Haswell!

    This thing will be a beast,

    8 cores by default (possibly 16 physical core "extreme" model)
    22-16 nm process
    new cache design
    on-package vector coprocessors
    FMA instructions (i've heard intel is using fma3 and amd is using fma4)
    128kb L1 cache
    1 MB l2 cache
    16 MB l3 cache shared between cores

    also features intels new turbo-boost and of course the pci-e controller on the die.

    Why would they bother making 8 physical cores when many applications still don't take full advantage of 4? I imagine that 8 will probably be out of the "sane" region of processors for a while, even among extreme enthusiasts.

    What is a vector co-processor? I only found one article on it.

    Windows 8, out around January 2013 is Suspect should have improvements for these multi core CPU's.

    AMD currently makes 8 and 12 Core CPU's for their Opteron Line.


    Though the big thing with multi cores like those, are for Workstation and Server software.

    Carrara 8 Pro that I use for 3D stuff once in a while, can support up to a maximum of 16 Cores per PC/Node, either 2x 8 or 4x4 or 1x16, or in the case of using Hyperthreading, 2x4 (8 Threads per CPU = 16)

    Thats just one example.



    I'll admit I'm not too thrilled about Sandy Bridge myself either.

    the current Socket 1156 and 1366 CPU's are still plenty powerful, and should of been improved upon for at least another year or two IMO. instead of these 1 or 2 Year stints before moving on to the next platform.

    Seems 1155 currently only supports Quad cores, which seems kind of dumb to me that they would do this, considering 1156 is the newest before it and been out the least amount of time, and supports Dual and Quad.

    Socket 1366 only supports Quads, (not including the Dual core Xeons), or better,and has been out at least a year longer than 1156.



    And like I mentioned once before, Intel still has yet to release any REAL Sub $100 CPU's for their current gen hardware. Which they are losing a LOT of ground and sales to AMD as a result.

    Its like Nvidia Currently, All they offer in the Sub $100 Range is the GT 430, nothing else. and the GT 430, at least in the gaming arena, gets beat down by the Radeon 5670, and even the lesser 5570 in some cases, both of which usually cost the same or less.

    Definitely not happy about Intel Ditching Socket 1366 either. Would of been nice to see them keep 1366, and develop cheaper priced 6 cores for it, but guess not.

    Is there really even any good reason for Intel to switch around their sockets except to force upgraders to a new platform?

    IMO no, the improvements Sandy Bridge makes are no where near as significant as going from Socket 775 Wolfdale or Kentsfield/Yorkfield to Socket 1366 Nehalem/Bloomfield, or Socket 1156 Clarkdale/Lynnfield CPU's.

    I wish I could find somewhere that actually explains why its necessary to go to yet another socket platform for these two, versus just using 1156/1366 we have already.

    but IMO, the more Intel keeps this crap up, the more ground they'll lose in the long run against AMD on the lower mainstream markets, just as Nvidia has to AMD in past year or 2.

    I'm really beginning to dislike Intel. They seem like a money-hungry corporation with no respect for their customers.

    I hope AMD makes advances on them in the CPU department, although I'd say that the NVIDIA GPUs are better products than ATI's from what I've read.

    Has ATI's Linux support improved at all?

    I disagree...
    Granted Intel is in the business of making money, and they should be...
    Realistically they really didnt need to release a new chip that virtually made all previous chips obsolete.
    The high end 2600K outperforms the $1000 i7 975 extreme and at a $300 price point...
    What excatly is there to complain about?
