What makes a cpu better than another - Page 3

post #21 of 38
Thread Starter 
Ok, so the only thing making an i7 2600k better than a i5 2500k is just a mere 100mhz,(3.4ghz vs 3.3ghz) and just 2mb more of L3 cache? Those little differences net the i7 that much higher peformance?

And the i7 2600K has hyperthreading, its good in heavily threaded programs.

Hyperthreading and possibly slightly higher binning quality with the i7.
In benchmarks? You'd most likely see a difference.
Gaming? Depending you have SLI or Crossfire you may see a few FPS more with the i7.
Encoding,multi-tasking,folding,etc. take advantage of HT.

Ok, a better example, my current cpu at stock 3.4ghz quad core. I5 2500k, 3.3 ghz quad core. phenom 965 has larger l2 cache. I'm not sure if the phenom supports multi threading, but if not neither does the 2500k for hyper threading...so what makes the i5 better here?

p.s. not exactly sure what the 4000mhz of hyper transports does for the 965..

Architecture makes the i5 better... More performance, more features, and lower power consumption. The i5 is just a better chip nearly all the way around.

I'm not fighting you on this or anything, but how does it get better performance just because of the architecture? Is there more to a cpu's performance past it's actual specs? Lower power consumption i can see due to a smaller die right? 45nm or w/e it is.

32nm core architecture chip die with some encoding and or encryption features.

Ah i see, man I love how intricate this stuff is

The architecture is everything, better designs, more instructions per clock, increased clock speed and fewer transistors to do the same job. This is where chips begin to get complicated and takes time to read and learn how a processor works.

I see, I'll have to look into that, rep'd, if it matters to you thanks for everything
