Review AMD Ryzen 5 9600X and Ryzen 7 9700X Review: Zen 5 brings stellar gaming performance

[jeremyj_83]

Where are you getting those numbers from? The testing on Tom's Hardware shows approximately a 10% difference in performance between the two for Microsoft Flight Simulator.

Its almost as if the difference in performance is nearly identical to the percent difference in clock speeds.

Ryzen 7 5800X3D	$310 ($449)	8 /16	3.4 / 4.5		100MB (4+96)	105W	DDR4-3200
Ryzen 7 5700X3D	$229 ($249)	8 / 16	3.0 / 4.1	-	100MB (4+96)	105W	DDR4-3200

Looking at the 1440P numbers again, its looking like a platform upgrade to AM5 is questionable at current prices.
I've got a 5800X and I'll probably be GPU bound on anything up to a 4080 at 1440P or 4k.
If I need help with one percent lows, it seems like a cheap 5700X3D will fix the problem.

I'll be very curious to see if the AM5 chips start looking better at addressing one percent lows in Win 11 24H2.

It's almost as if you are wrong, check above

Wait, hang on - which page is the chart you posted from? It's definitely conflicting with the two charts from the page I linked (the 5700X3D review):

Spoiler: Chart 1: includes PBO and other variations

Spoiler: Chart 2: De-cluttered version of Chart 1

It's from this very review, that's why I posted it here.

Ugh, forgot that this was the one Ryzen 9xxx thread that was a review, and not a separate 9xxx thread.

This is so bizarre, because most of the other chips common between the two tests are pretty much within margin of error, but somehow the 5800X3D has gained 9.6% on the average fps, and 16.9% on the 1% lows when tested this time around. No idea what that's about.

There are other games that show odd behavior as well. Borderlands 3 had a big gain for 5800X3D on the new review and Hitman 3 had a huge gain for the 5700X3D on the new review. I wonder if it is driver related.

I wondered about drivers as well, but was sort of mentally dismissing that because the 5700X3D and 5800X3D are practically the same chip, just different clock speeds.

What driver difference would change the performance of one but not the other?

Very true. Does make you wonder what is going on.

The only reasonable explanation I can find on why two identical CPUs would perform differently under the same circumstances is that the RAM subtimings are different. There's a few subtimings that, unless you notice them, they can change performance slightly under certain scenarios. When you set XMP, the motherboard gets to decide most of the subtimings and that is almost always random. Some cheaper motherboards don't even expose them. The rest is just Windows having random services running during tests, but less likely in a controlled envronment.

Usually you don't go that deep when configuring test benches, unless you're specifically testing RAM, I'd say? Happy to be wrong on this one.

Regards.

Got my new 9700X system up and running this weekend. Before I tore out the components I was keeping I did a Civ VI Gathering Storm AI benchmark (CPU intensive). On my old 4770k each turn averages 52 seconds. On the new system, same SSD for the game, it dropped to 27 second average with both on Win 10. A decrease of almost 50% or a 93% performance increase. The new CPU never went over 50% usage either (old one was around 90% during the benchmark) so it was all uArc and clock speed that caused the huge performance increase.
