Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

I'd agree. We need one of those 30 game comparisons that HWUB is known for to truly grasp how different games react to the cache. Right now, the results (and averages) can swing so wildly depending on the games tested.

I am sure Voodoo will do on of his roundups over on reddit in a few days. I think both are very close but a DDR4 system close to matching a tuned DDR5 system is pretty good going when you consider the price difference.

$450 for the 5800X3D + $150 for a mobo + $150-200 for good ram and you are good to go. Intel side you can pay a bit more for the better all around performance of the 12900K but get slightly worse gaming performance or you can pay a lot more to get DDR5 as well to eek out a win in the gaming on average.

What we need is a complete test suite with LOWs.
I think that his is even more important to know.

These value comparisons are a bit disingenous since we are ignoring the fact that there are cheaper CPUs like the i7 12700F that when paired with DDR5 could well be a match for a 5800X3D in gaming. Of course, if you insist on *only* comparing the 5800X3D to the 12900K, then sure, you can get competitive performance for far less overall cost with the 5800X3D.

That DDR5 6400 is about as much as the 5800X3D so any saving you get on going with a 12700 you instantly lose if you want to go with that level of RAM. Slower DDR5 will reduce the performance and still cost more until you get to the point where you might as well save money and go DDR4 in which case the price difference is not all that great and you will see 20-30% gains in some cases, if those are games you play then the 5800X3D can be a good choice for some new builders.

Might be good to see if highly tuned DDR4 can help ADL a bit more than the 5800X3D as if so that might be a viable alternative.

Are you sure?

I think with a large enough pool of games the 5800X3D would win on average. There are probably enough titles like Factorio where it's stupidly far ahead of everything else which will drag it past anything else.

That is pretty poor DDR5 lol. Probably more expensive than the DDR4 3200 still though.

Yeah, I don't even want to think about the latencies of DDR5-4400. Geez, I honestly think my B-Die 3600s might be able to clock close to 4400 with loose timings and extra voltage, they easily do 4000 @ CL18. Honestly defeats the purpose of DDR5 if you're gonna go that low in clockspeed, you lose all the bandwidth advantages and take a huge hit in latency. Whats the point?!

Back to our discussion, a 12700K (DDR5-5200) is right on the heels of a 5800X3D (the lows are relatively stronger on the 12700K too it seems)

Are you really Grasping at Straws at this stage? Are you going out of your way to purchase DDR5 6400 RAM to prove that you are less than 1% higher on an average of 8 games? Really?

This is the price is no object king right???

Otherwise either of these is kind of dumb overkill for gaming.

You could drop in a $200 CPU in these gaming rigs and no one could tell the difference without looking at a frame counter.

And 199/194 = 2.6%, not less than 1%.

Besides pure performance it's just impressive how efficient Zen3 with V-Cache is.

I'm just excited for the next Ryzen CPUs. Zen4, new Node with TSMC N5, probably paired with V-Cache. Just let me dream!
I don't think there will be Zen 4 with stacked cache available for some time. Technical reasons (5nm stacking is newer still) and no reason to rush it when Milan X is probably good enough for the cache sensitive workloads.

Would love to be wrong about that however.

Lol, not as impressive as the 5700X in that benchmark, for some reason.
Yeah, it's a pretty good gaming CPU as it beats both the 5800X3D and 12700K on that benchmark.

The take away from all of this testing is that if you have a very recent CPU worth more than $200 you just need a High End GPU
