5 Generations of Core i7 Processors: 2600K, 3770K, 4770K, 5775C & 6700K Gaming Comparison

not necessarily

In 2014 I move from an i7 920(4GHz) to an x5650(4.2GHz) and it did nothing to me in gaming, a few days ago I move from x5650(4.2GHz) to i7 6700K and the difference in games especially minimum fps was big, and that at stock and without xmp, I will OC later this week.

Also in paint.net(a program that use 100% all 12 threads of the x5650) that I use a lot it was around 10% faster with the 6700K at stock and without xmp!

Well, it's purely subjective. I for example, dont believe the extra £~550 is well spent on that upgrade. You do.

I could put that towards a new GPU and SSD storage or something.

An X5650 is the same core as a 920, just more of them so you're not going to see any difference in a lot of games

You would however see a huge difference in the same games from moving to a Haswell i5, or Ivy Bridge, even Sandy Bridge.

Moving from Bloomfield to Sandy Bridge is about +15%, Bloomfield to an Ivy Bridge is about +3%, Ivy Bridge to Haswell / Devil's Canyon is about another 3%, Devil's Canyon to Skylake about 5%.

So since Sandy Bridge to now we have seen total gains of less than 15%, from Bloomfield its about 25%.

I would argue £550 to upgrade from Bloomfield and X5650 is worth it but not just because of the performance difference.

Sandy Bridge and later are platforms worth hanging on to, the money is better spent on a nice GTX 980 and an SSD.

Shame my 3570k wasn't in that but it was marginally slower than the 3770k anyway so I think I am set for another generation or 2.

btw what I observe is 60% performance gain in applications that use 1- 4 cores.

in cinebench a 5820k 4.6 is twice as fast a stock 3770k

so in things that benefit its a nice upgrade.

I do nothing of that sort so all I really look at is gaming.

But is the move from a i7 920 even worth it? At £500-600 even that is debatable.

Intels upgrade options have become embarrassing over the last 7-8 years.

I went from i7 920 @ 4.4ghz to my current platform in sig - it was a noticeable upgrade.

Thanks for sharing - interesting watch.

It supports my long held suspicion that the gfx card really makes the lions-share of difference, if the storage medium, amount of ram and amount of cores remain fixed.

Disappointing how AMD have NOT been able to close the gap significantly (or is that just noticeably) during these product life cycles.

Some nice comparisons in this thread, tyvm for the info

Wrong thread - delete.

I upgraded from a 4.6 ghz ddr 2000 sandy bridge-e to a 6700k at 4.75 ghz ddr 3700.

the difference in heroes of the storm is night and day. I got a much more consistent frame rate and also 100fps mins instead of 60-70 fps mins. and this also includes a resolution bump from 1080p to 1440p.

so for me the upgrade from sandy bridge was well worth it.
