rdr09 My bad. Heaven score seems low.

My take is, aside from an underforming 3900X, at 1440 the games or even some synthetic benchmarks are gpu limited. A lot of reviews been out showing the 3900X is just a smidge slower than even a 9900K.

Here is an example.

reqq that geekbench 4 score is bad.. i get 50k at stock with pbo off If you havent..you need dram calc subtimings on memory, huge difference! Primal timings not enough.

Op - when you oc'd the ram did you also bump up the IF? Overclocking ram above 3600mhz breaks the IF 1:1 lock and severely hampers performance.

faster in average FPS? is this possible?

AllenG Sounds like ram compatibility issues... or the board is having an issue. Try your two ram sticks in the other 2 slots. If your running 4 sticks, drop back to two and see what happens. I've seen horribile performance come from ram kits that insist on running combinations of timings that Ryzen seems to HATE. XMP hasn't ran stable from any ram kit i have used so far, even the ones meant for Ryzen. Seems each Ryzen has it's own likings and writers of the xmp profiles arent accounting for that apparently.

Rest assured that Ryzen CPUs are a good investment and for the price, I would go that route myself FOR SURE but right now we are in an awkward between phase where the games that are really going to take advantage of these CPUs are not out yet and the games we have now were all designed for Intel CPUs and DX11 code, in which the GPU prefers a higher clock on the first core as it is unable to communicate directly with the rest of the cores. DX12 solves this issue but no games are really taking advantage of that yet. The DX12 games that exist now are really just scratching the surface of what DX12 has to offer.

REST ASSURED a Ryzen CPU is a solid investment. It's time to shine is yet to come.

You are right about DX12 as Hitman the only game that showed improvement in all stats although F1 2019 didn't.

Come off the clock speed dude. It literally means ZERO. What matters is IPS. I have a FX cpu's that can outclock your Haswell....so what? I also have tons of benches where a Ryzen with lower clock speed has better performance than a higher clocked run. There are TONS of variables.

With any other titles, the difference will shrink.

There are probably no more than 5 games out right now that anyone can show a real difference in performance in with more than 8 threads and in all of those cases, 8 threads is still very strong performance wise. Ryzen 3rd gen is likely the PS5 CPU and until PS5 style games come out, done expect to see big gains on ryzen.
this, and why I'm not upgrading anything until post console release releases, & at that point I'll likely be going team AMD for the first time in 15 years as they'll sell me 40+ lanes for way less than intel will.
oh, i will be adding the CRG9 monitor by the end of the year though. That's a perfect balance of resolution and frame rate... least, as an ex-eyefinity/surround gamer.
