Ahh, now that's the info I need to remember. Sure, the Bulldozer seems promising, but what about Sandy Bridge?

sandy bridge has been out for more than 6 months, we know its performance. i think you may be asking about Ivy Bridge. (lintel's next processor) that is unless your asking about enthusiast edition Sandy Bridge.
Ivy Bridge is the worlds first production processor produced using a tri-gate transistor, aka 3D transistors (as dubbed by Intel). the idea behind it is to increase the surface area by three times while consuming less space horizontally on the die. this methods also extremely more efficient than a regular transistor and will allow lintel to greatly increase the clocks on Ivy Bridge. Not to mention Ivy Bridge is also going to have the smallest transistors of any mass produced processor that isn't ARM. (22 nm)
final info on Ivy Bridge is scarce and as of right now its engineering samples are only producing marginal improvements over the final silica Sandy Bridge. (normal for most processors till they reach their final code/silica) Intel's plan is for roughly a 20% increase in processor performance.

I will wait then and jump on the Ivy Bridge processors then . I'll change my mobo as well at this time so i'll be ablle to have theh p0wer X3

to try to keep it short i'm going to SUUUUPER simplify it. (now remember this is 'simple' for some one whose read a lot on this) (general info that should be known)Intel introduced Hyper threading back in the days of the Pentium 4 which had an extremely long pipe line. (last gen P4's had a 42stage pipeline) long ass pipelines are fine and actually Faster than short ones when doing a single task, however the problem with them is that if the code guesses wrong on whats to be done when and how then the whole processor stalls and dose nothing. to counter this it added insertion points in the code to counteract this by allowing the OS to insert processes in the inactive portions of the pipeline. this is Hyper Threading; processing more code in less space. however hyper threading fails if the code path is efficient and renders properly. (not to mention less needed in modern processors that sport pipe lines of less than 15 as the penalty of a stall is far less) That sounds like pipeline optimization, or superscalar processing (While Hyperthreading technically does optimize the processor pipeline, it doesn't really seem to be what you described here.) Hyperthreading is simply the duplication of the status registers for a thread or process, so that a processor can easily process 2 different threads or processes. For single threaded hardware, If a processor wanted to change threads or processes, it would have to store the info of its current status registers in cache or memory, then load up the info for the other task into its registers. Hyperthreading reduces this overhead since it already has the task info in its second set of registers. what you ultimelty need to take form that is, Hyper threading only helps if the code is poorly written or the processor incorrect guesses the work. [/u][/quote] This is not necessarily true either, provided the OS has a decent task scheduler hyper-threading can still provide performance benefits.

Oh yeah, Ivy Bridge is the other, anyway, can't seem to be sure, so far, Bulldozer does sound good to me. But sadly, my current laptop as I promise myself to be as future proof as possible.
Moreover, even the existing Galaxy S II is also going to be obsolete too quickly when you're not forgetting to look into Nvidia's Kal-El. Hate to be off topic, I'm also confused about which one is better? Dual Core 1.2 Ghtz VS Single Core 1.4 Ghtz?

i love having you around Atecom, you do a good job of correcting me when i'm wrong or a little off. helps with getting this stuff right latter. i completely forgot about the duplication of registers... what you ultimelty need to take form that is, Hyper threading only helps if the code is poorly written or the processor incorrect guesses the work. [/u][/quote] This is not necessarily true either, provided the OS has a decent task scheduler hyper-threading can still provide performance benefits.[/quote] i was bound to make a few more mistakes after typing up as much as i did...

some good news and bad news for anyone in the market for a GPU or recently purchased. ATI (**** you AMD for getting rid of the ATI name) is having fabrication problems and as such is delaying the launch of its 7xxx class GPU's for some time. apparently their move to the 22nm manufacturing systems turning out to be as problematic as Nvidias move to 32 with Fermi. Nvidia however wont have a competitive product till early 2012 so AMD really isn't in any rush. the good news is that roomer has it that ATI's 7xxx top tear cards will be featuring XDR2 RAM modals in hope of saturating far past what Nvidia and DDR5 will be capable of. www.tomshardware.com/news/amd-HD-7900-XDR2-Rambus-Memory,13408.html looks to be an interesting change in graphics performance if XDR RAM proves to be all its cracked up to be.

Nvidia just tossed that curve ball its been needing to take the lead. now lets see if manufacturers can reconise it. Ive always wondered why this type of thing has been done sooner. really wouldn't mind a move like this to come to full sized computing either. not like i need to eat 120wats while surfing the internet like my current computer dose. (but i don't want to be limited to mediocre performance like the 60Watt desktop i built my parents)

Well, AMD has finalized the release date for Bulldozer, October 15th. hopefully they will stick to it this time! also from the numbers i'm seeing Bulldozer wont out pace Sandy Bridge in shear single threaded applications but anything that requires multiple cores it will out pace it all the time and when gaming with more than 1 monitor its should out run Sandy Bridge too. but for all i know these numbers could be more BS. lenzfire.com/2011/09/amd-bulldozer-fx-processors-benchmark-results-vs-core-i7-2600k-70406/

Wow, that's impressive, although there are some weaknesses.

AMD i am disappoint. www.anandtech.com/show/4955/the-bulldozer-review-amd-fx8150-tested/1www.tomshardware.com/reviews/fx-8150-zambezi-bulldozer-990fx,3043-24.html a failure in almost everything except special conditions and even then it only manages to barley outpace a 2500k... I smell a rerun of the Pentium 4 era all over again and this time the maker cant rely on market dominance to stay alive. some dark days a head for AMD. Bulldozer cant even outpace PhenomII X4's at lower clocks in a lot of things.man, looks like i'm going lintel again for my next build. should of jumped on those sails for Sandy bridge parts i saw last week... (could of saved my ass a good 200$)

ok got a question for the other geeks on this thread. after the disappointment of Bulldozer i'm heading to Sandy bridge for this rebuild. (what i want is hi frame rates and bulldozer lacks that) im eying the i5-2500k as i don't have any use for hyper-threading and the 100$ savings is a lot. (planning to overclock) for motherboards im having a hard time getting some good reviews for z68 motherboards. however i have fairly well settled on one of the following boards. (i cant find reviews from my favorite sites however other sites have given the boards good reviews) ASRock Z68 Extreme4 185$LINK ASRock Z68 PROFESSIONAL GEN3 255$LINK im not adverse to spending more money for better quality and features, i went cheep with my first computer and have regretted it. i'm just wondering if anyone knows of some better boards. (would like to keep to UEIF)
while were at it, heat sink suggestions are welcome too.
