core 2 quad q9400 vs q9650

[TMAGT98]

I'm currently using c2q q9400 CPU with 8gb ram machine to run adobe lightroom. Performance is decent.
i know this is not the perfect setup for such programs. I'm going to build a i5 rig in near future.
But for short term use,
Will i see a considerable performance increase if i upgrade to a q9650 CPU? Will i get roughly the same performance as q9650 if i overclock my q9400 to 3ghz? Is q9650 marginally powerful than q9400?

Thank you.

They are identical CPUs apart from clock frequency and possibly power draw at 3GHz.

The Q9650 will be 10-15% faster than the Q9400. If you can overclock the Q9400 to 3 GHz, it will definitely perform close to the Q9650.

The Q9650 has 12 MB cache and the Q9400 has 6 MB cache. I don't know how this will affect performance as the effect of cache sizes has not been clearly documented. However the performance delta, if it exists, must be less than 5% when both processors run at the same clock speeds.

If I had a Q9400, I certainly would not upgrade to a Q9650.

BTW, if Lightroom is your main application, you may want to look at AMD's R5-1600 instead of an i5.

It would be a very minor upgrade. Not really worth the hassle of removing the heatsink and Q9400 from your current PC, then cleaning the heatsink and applying new thermal paste when installing the Q9650. Unless of course the Q9650 is dirt cheap.

Is ryzen 5 more powerful than similarly priced i5? I'm going to build a 6th gen i5 rig. But i live in Sri lanka. My local pc market is mostly intel based.it's hard to find budget amd parts in Sri lanka. Only premium amd parts are easily accessible. My budget is bit tight and i want to spend as low as possible for components except CPU and gpu.

Should i really invest in amd ryzen anyway?

not worth upgrading that cpu/mobo/ram to be honest save your funds and get an i5-4xxx series CPU/MOBO DDR3-1866 and enjoy

Based on USD, AMD's Ryzen has much better bang-per-buck than anything from Intel at a comparable price and the R5-1600 has the best bang-per-buck of all Ryzen CPUs currently available. In more heavily threaded workloads, the R5-1600 is on par with an overclocked i7-7700k while costing ~$150 less when you factor in an adequate aftermarket cooler for the i7 which comes with none included.

The R5-1600 would be 2.5-3X as fast stock as a 3GHz Core2Quad.
