I have read in a website that the sb-e is about 4% faster clock-for-clock than sb, is that true?

1. Ivy Bridge will be the new platform to move to that makes economic sense for most when games begin utilizing 6 cores or more.
2. The big question to answer is when exactly will we see games really start utilizing 6 or 8 cores in a way that will move us to begin making those upgrades. Will it be 6 months, 12 months, 2 years??? An extra 3-6 frames going from 65 top 70 fps doesn't make anyone want to spend another 800 dollars or so for SBE.

Till then SBE seems to only make sense for those who use apps that are really going to make use of those extra cores and games just don't at this time.

Here is clock for clock performance as benched at [H]. As you can see it is slightly slower in all three benchmarks.

In general, I would think the above is true (i.e slightly slower than SB) because of the larger cache latency (due to the increase of cache size to 15MB from the 8MB on the 2600K) and the complexly related to two more cores. However, if a certain program/bench loves big caches then you might see SB-E pull ahead clock for clock. Again, this is really minor stuff. I would not think any of it would be noticeable during normal use.

Also, don't forget about clock speed. SB should clock further due to less power draw and way less heat output all else being equal (i.e. same cooling setup). If you remember the original SB reviews, many reviewers had their chips OC'ed to 5Ghz or above, whereas if you read the SB-E reviews most show an OC of 4.6 -4.8GHz. That should tell you somehting about likely 24/7 clockability.

If you compare a SB chip running 100-200MHz faster than SB-E... then any small clock for clock improvements will be lost and you would only see an advantage in games that are coded for more than 4 cores (very very few games meet this requirement) .

EDIT:

Disclaimer -- Since it does not seem to be relevant to the OP, I am neglecting the PCI-E bandwidth advantage of the SB-E platform which may lead to benefits in 3/4 GPUs and 3 screen environments (waiting for reviews with this type of setup). For now I will say that in that extreme case you may see gains in a large number of games with SB-E.

my opinion is that all SB owner are angry and mad because SB-E is out, face the fact 6 core is better than 4 and just wait till the 3.0 PCIE video card come out.........

i can't wait for this coming wednesday to order my new system X79 asus extreme board and the 3930K in newegg.....and

I want to see my new score in 3DMARK 11..

Trust me, I'm glad that I wasn't tempted to pay triple the price of a 2600K for only 2 extra cores.

2700K - 369.99
3930K - 599.99

Not even close to being double the price here in the states.

If your primary concern is gaming, put the money you save from NOT getting SB-E + mobo (+ RAM) into your graphics card(s).

You'll see much better performance in games thumb.gif

To all the SB-E users, this is what reading Bulldozer threads is like for some of us redface.gif

My CPU > your CPU instead of useful information about the chip itself

Gotta get my hits in on this dead horse. My opinion is if you play games like Crysis 2, Skyrim, BF3, WoW, etc...Then your money in fact would be better spent on something you can transplant into and Ivy Bridge rig in the future. Another graphics card would be good, Ram for sure, or maybe invest in a legit watercooling loop. I also recommend a gold/platinum PSU.

On the other hand. If you like to have LAN parties and play Cinebench and 3dmark all night then uh...sure SB-E is a great choice. Also theres the EPEEN effect.

I have the money to build a massive x79 system but i just can't justify it for myself plus I want other things
1. Surround sound
2. Watercooling for my 580 lightnings(HF Supreme VGA)
3. Aluminum heads for my LS1
4. point is, for me, SB-E would not be a satisfying purchase
