I have a Sandy Bridge I5 2500K and I was wondering if there would be any difference in performance if I upgraded to a Haswell I5. I suspect no since there is almost no compition from AMD and Intel has only made very small changes over the last couple years, so small that it isn't worth upgrading unless your hardware is really out of date like you are still using a core 2. I figured I would still ask though since I haven't been keeping up with hardware as much as I use to.

Pretty much what he said ^^.

Overall, Sandy Bridge is two generations back, and with a 10% improvement to Ivy Bridge, and another 10-15% to Haswell, you'd run into the problem with having not only to upgrade the CPU, but the motherboard as well.

If you wanted a quick and easy boost, you -could- jump to Ivy Bridge and sell your Sandy Bridge to get a bit more performance out of things with a minimal investment along with perhaps jumping to an i7-3770k.

Your i5 could sell for about $150. Buy a i7-3770k for $280 - so a net outlay of $130-140 would jump you a generation, HD4000 integrated graphics, hyperthreading, and a pretty decent increase in performance.

Plus, the MOBO should be compatible as both Sandy and Ivy Bridge use the...

Plus, the MOBO should be compatible as both Sandy and Ivy Bridge use the LGA1155 socket, just doublecheck your MOBO docs to verify compatibility.

Actually assuming the same clock speed, the increase in CPU performance from Sandy Bridge to Ivy Bridge is on average 6% based on many different benchmarks. Going to Haswell is another 6% on average so the performance difference from Sandy Bridge to Haswell (assuming the same clock speed) is a little over 12%.

Not sure how much of a performance improvement Broadwell will be, but considering Intel has been focusing on reduced power consumption and improved integrated GPU performance since Sandy Bridge, I would guess another 6%. Or about 19% - 20% for a Broadwell CPU compared to a Sandy Bridge CPU.

Since Skylake is a total different CPU design, people are hoping that it will provide a 10% - 15% performance improvement over Broadwell. But that CPU is not expected to be released in Q3 2015. If you feel that your CPU is providing you with enough performance, then I would wait for Skylake... which is what I would do.
