Why is the i5's Performance so much better even though stats are the same? - Page 2

post #11 of 49
You can't overclock a Phenom II on standard air/water high enough to match an i5-2500k @ stock.

The other problem is that the i5-2500k has a much greater overclock ceiling, hitting around 4.7-4.8GHz on air full load stable without heat issues.

Price - Performance the i5 2500k is top dog.
Unless you can unlock yourself a Phenom II x2 555
Which is half the cost and will perform almost exactly like a 955.

Sandy Bridge is just the place to be right now, it's a sad time for AMD processors.

AFAIk nothing from AMD keeps up with Sandy Bridge at the minute, Intel are just too good. AMD engineers are all asleep...

Nah just kidding hehehe Check out this anadtech bench of the 2500k and the X6 1100T Black Edition (the best amd chip on market to my knowledge), both at same clocks, and the AMD chip even has TWO MORE CORES plus more L2 cache...but it still has no chance.

On that test, the 2500k won 33 out of 37 comparisons between the two. Very impressive Intel

guys he's comparing AMD and Intel, not Intel i5 to Intel i7.

Its not possible, AMD's architecture is too far behind. Bulldozer is coming out in September, and it is going to at least partially catch them up performance wise.
Though Intel will release SB-E and IB soon enough and AMD will be far behind again.

Here are some charts that should show you the difference, also why not to buy a 6 core thuban for a gaming build (still pII arch)

I hope you don't actually think this is true, more cores does not mean better for gaming since most games aren't encoded for multi threading.
Stock clock speed is largely irrelevant.

IDK though, a lot of the things you have been saying are quite foolish.

1. Manufactuering Process (Lower is better)
2. Number Of Cores (Higher is better)
3. Stock Clock Speed (Higher is better)
4. TDP (Lower is Better)

When we put all these things into perspective you will find the Core i5 2500k is a much better CPU.
Says the person with the Phenom in the sig rig. That's big coming from an AMD user. Thanks for not being a fanboi!

Re-read first post. cpu is not only for gaming.
OP did not specify which games he plays.
