AMD claims the processor will produce 34 percent more performance than the existing "Shanghai" quad-core processor

Adding 33.3% more cores increases the performance by 34%? WOW!

I'm seriously wondering if they didn't just pull that number out of their asses based on the number of cores, or if they did any extensive testing.

i wonder if you did some extensive search on their claims or you just pulled your comment out of your ass ?

Very good point. Both are 45nm, so how can they add 2 cores and keep the same TDP while adding more than the theoretical possible of 33.3% performance?

What research? No one has their hands on this processor yet, other than AMD. And AMD hasn't gone into detail on how it achieved those numbers.

I said "I wonder" because I have no idea, simply the fact that they got that percentage is what I find curious. The scaling in performance is rarely that large when adding cores.

wait and time will tell ;)  maybe they left out the part where they changed a bit the core architecture, or against what they chose to compare performance since we all know the intel adds up to 85% more performance in multimedia(compared to what ??) buy intel now ... etc :)  marketing stuff :)

How about we all learn some math before we post. 2 more cores mean 50% more cores right?(50% * 4 =2) So the theoretical maximum performance gain is 50%.
It's 34% because not all applications use 6 threads.

Having a 4 core processor and udgrade it to 6-core is a 50% upgrade not 33%. So we have a boost of 50% more cores and 34% boost in performance. Correct me if I'' wrong! Nevertheless it seems to be a very good product that will press more the cost for the 4 core processor

4 cores out of 6 means 66.6% so the 6 core CPU has 33.4% more power :)

4 out of 6 cores is 66.7% represented as a fraction. Going from (keyword being increase) 4 to 6 cores is a 50% increase. We are comparing the gains of increasing core quantity from 4 to 6 cores here.

Dyslexia of the mind maybe?

These are also server chips, so they are geared for low power and maximum throughput when implemented within a network of similar hardware. The 34% is believable given what they run is capable of using these chips' full potential.

I think this is great news for AMD, I hope the processor does have a 33.4% increase.

I can't wait to show my friend all of what's been going on in the technology space. He's been away for almost 2 years serving a mission, and has no idea about i7, physics and gpgpus etc. I'm trying to think of how best to blow his mind :p

The Istanbuls have 6 cores.
6 was the number of main characters on the show Friends.
Friends had Matthew Perry as one of the characters.
Matthew Perry starred alongside Bruce Willis in 'The Whole Nine Yards'.
Bruce Willis starred in '12 Monkeys' with Brad Pitt.
Brad Pitt starred in 'Sleepers' with Kevin Bacon.

6 degrees to Kevin Bacon! HOOWAH!

Wait... if they released it already... then that means they jsut beat intel to the 6 core.

You said 4 cores out of 6. This means the reference is the 6 cores.
So the 6 core has, according to your calculations 0% more power (the reference is itself).
I can't believe we are discussing this on THG.

now we are getting there AMD. This advanced release (pending it was THOROUGHLY TESTED) is a great way to take more of Intel's market. I personally wont be upgrading until the 16core 64 bit comes out, for a reasonable price. I switched back to Intel Duo Core a while back... because I need processing power and floating point calculations for 3D Rendering (yes at home).

Basic math.

Comparing the number 4 to the number 6.

It is correct to say that the number 6 is 50% bigger then the number 4.

It is also correct to say that the number 4 is 66.66666% of the number 6, or 33.333333% smaller then the number 6.

It is NOT correct to say that the number 6 is 33% more then 4, it is also not correct to say that the number 4 is 50% less then the number 6.

Both percentages are correct, 33.3333 and 50%, IF you state them correctly.

6 cores is a 50% upgrade over 4. 4 cores is a 33% downgrade over 6.

Intels 8 threads = AMD's 6 cores no doubt, higher IPC and memory bandwidth all helps

Gin FushichoIts a socket 604 I dont believe it to be a true 6 core.


Ah not this old bullshit again - how many cores total? 6? THEN ITS 6 CORES

DjEaZy... alright!!! ... and how long till it come to desktop?


i7 6 cores are supposed to come when the i5's get released so that people will see the differences between high end and mid/low end etc, what i wonder is when were going to see a naehlem based celeron LOL

since when do we run just one app on our pc?
