Sandy Bridge Reviews

[edplayer]

What about it? Its not some law of physics. And diminishing returns are happening but the examples he is posting are cherry picked to make it seem like a bigger deal than it is.

Filter through all that and it looks like things are OK. He even snuck this in:

I will say that compared to a stock Core i5 760 2.8ghz, the 2500 at 3.3ghz is a massive improvement If SB clocks to about 4.6-4.7ghz on air at reasonable voltage, I might get one just to play with it; but then I'll still want a 6 or an 8-core processor in 12 months .

Yes. Look at Wolfdale (Penryn) vs. Yorkfield (Conroe) chart at the bottom of page: http://www.anandtech.com/show/2215/3

In some cases like DivX, the performance increase was 50% faster from Conroe to Penryn.

Not according to the actual review. There's a little thing called "Average" and there's also "Optimizations".
http://www.anandtech.com/show/2362/4

Penryn's average is 5-7% and Sandy Bridge has AVX for optimizations. If you remember Pentium 4, the SSE2 instructions just extended the registers to 128-bit from 64-bit and the FP unit was kept the same. Core 2 brought the 64-bit FPs to 128-bit. Sandy Bridge will extend the registers to 256-bit and bring the FP units to 256-bit.

I presume that Socket 1156 coolers are going to be 100% compatible with Socket 1155?

That's the word on the stre... err interweb.

Pentium D was pure trash. Athlon 64 was killing it those days. I would say the jump was from Athlon 64 to Core Duo. It was Intel's need to save face that caused them to completely change their development track. Such a jump could only happen again if Intel has a dog of a product to start with.

Yep, Athlon 64 was just as much of a jump over Pentium D as Core 2 was over Athlon 64.

AMD is in the position to make such a leap, but I doubt we'll see them do it simply because Intel is doing so well and not stagnating (contrary to some recent opinions).

So what brand of air cooling solutions are recommended for the 2600K for overclocking that will fit the new socket? Using an Ultra 120 now for a C2 E8500. Let's say that would fit on that new Asus Maximus IV P67 mobo.

Ultra 120 would be fine for 2600K overclocking

That would work fine but you will need to get a new mounting bracket. I doubt the mounting holes are the same. They weren't going from 775 to newer sockets.

 

[IanWorthington]

Why are people on this thread talking about overclocking *and* the IGP in the same breath? Don't you need the P67 for the former and the H67 for the latter, or have I missed something?

Yeah that's what I thought, I knew the mounting holes would be different, I wonder if I could get just a bracket for it? Maybe I'll just wait to see what the reviewer sites will be recommending for it since I'll probably sell my current set up to help finance a new build. :whiste:

 

[Majic 7]

To Grumpy: Micro Center has a selection of mounting bracket kits and Evga had some boards with dual mounting holes so you could use your 775 cooler, mounted a little crooked but it worked. There should be some alternative available.

AMD is in the position to make such a leap

Most early rumors point to Bulldozer being 15-20% faster per clock than Phenom II. Therefore, AMD is no position at all to make the performance leap that Core 2 Duo did over Pentium D / Athlon 64.

but I doubt we'll see them do it simply because Intel is doing so well and not stagnating (contrary to some recent opinions).

Interesting. So you think that going from Pentium D to E6600 2.4ghz dual core in 2006 to Q6600 2.4ghz in 2007 to Core i7 920 in 2008 is comparable to going from a 2008 Core i7 920 to a 2600k in 2011? Intel is improving, at a snail's pace in the last 2 years though. I am sure most 2008 Core i7 920 owners won't bother at all with the 1155 platform. You couldn't say that to the E6600 S775 owner in 2006 when Core i7 920/Core i7 860 arrived.

Newegg has Core i7 950 3.06ghz for $290. So if anything 2600k should be compared to Core i7 870 2.93ghz or Core i7 950 3.06ghz at minimum. The performance difference is not commensurate with a 2011 new generation CPU compared to a 2008 architecture. Once Bulldozer ships 6- and 8-core processors, I hope we will quickly see Intel release 6-core SB at more reasonable prices because this idea of selling a $300 4-core processors in 2011 is just Intel nonsense (which I am sure shareholders love).

To Grumpy: Micro Center has a selection of mounting bracket kits and Evga had some boards with dual mounting holes so you could use your 775 cooler, mounted a little crooked but it worked. There should be some alternative available.

Asrock boards will also have support for Socket 775 coolers. :thumbsup:

Last I checked a TRUE will fit on socket 1156 so why would he need a new mounting bracket for socket 1155?

As far as I know, the mounting holes are the same as 1156 and that the coolers are compatible.

You need H67 to use the IGP (except for video transcoding). You can overclock with both. http://www.liquidnitrogenoverclocking.com/news_09.shtml

wow thats odd because I thought that the slides I saw said full cpu overclocking for the 2500k/2600k was only available when using P67.

OK cool then, I like having the option to be able to reuse it since it's done such a great job cooling my E8500 all this time should I need to. :thumbsup:

E8500 is 775 not 1156.

Aye, they do. Wonder what the story is.

It wasn't Pentium D-->Core 2, it was Athlon 64 X2-->Core 2. Intel Pentium D wasn't the top chip of the day, AMD's chips were.

Q6600/QX6700: I don't know, but the benches here make it seem the advancement is pretty small in most apps and nothing in games: http://www.anandtech.com/show/2112/17

AVX optimized apps will trash doubling cores anyway.

Core i7: http://www.anandtech.com/show/2658/19

Ehh, small gains in games, some are even slower than previous generation and general purpose apps show small gains. Not only that you had to buy expensive X58 chipset boards and 3-channel DDR3.

 

[GrumpyMan]

E8500 is 775 not 1156.

Yeah I know that, I was wondering about the air cooling options and if a an Ultra 120 would fit the new socket and if not, what would. Got my answer, but thanks.

 

[Absolution75]

didn't read the entire thread - anyone notice newegg has a single SB processor listed (OOS)?

WTF, did they just jump the gun a week early? http://www.legionhardware.com/artic...5_2500k_and_core_i7_2600k_sandy_bridge,1.html

Today Intel is launching their 2nd generation Core processor series which has become well known as Sandy Bridge, the architectures codename. This new architecture is exciting because it takes the Core design to the next level, providing a level of performance and efficiency previously unseen. Intel has supplied us with samples of the Core i5 2500K and Core i7 2600K, which we put through a battery of tests...
