In this case, "faster" is relative. Is a 13900k faster than a 9800X3D? Thanks to crappy NV drivers, apparently so . . . but only for ray tracing.

Probably due to more physical cores. Raytracing must really punch all eight cores hard and create too much cache pressure for SMT to be of much benefit. I would like to see SMT off results to see if the situation improves with the 9800X3D in raytracing.

Nvidia drivers could also be using the E-cores properly and offloading less important tasks to them, relieving the pressure on the P-cores.

It's been a while that I last used a Windows computer with Nvidia card (and last time I played video games was on C= Amiga anyway) — but isn't the actual Nvidia device driver single-threaded (on single-GPU systems)? That is, other threads coming from the game engines, not from the device driver?

In which case ist would likely be benefitial to have the driver thread running on an exclusive physical core = without SMT load on that core.

So having extra cores does help with driver overhead, at last on high-end NV cards. There was speculation that higher core counts would also help with Intel A580 driver overhead as well, and while those charts aren't direct evidence, it does seem to hint that they would be useful.

Moral of the story: fix your stupid drivers NV and Intel.

Then we should see improvement with the 7950X3D and 9950X3D? It isn't like the E cores are world beaters for gaming.

Would that even run in America with your 110V mains power? I thought things got a bit sketchy at 1.5KW for a normal outlet.

In the UK we can pull 3KW from a standard outlet and it is pretty cold here so it would double as a pretty good room heater as well.

US is 120v 15-20A so 1800-2400w our 240v is 2 120v dual phase and has 3600w+ of power. Old houses maybe but newer houses, 70s and later, should be fine.

In Europe there's a lot of strange things in some places. 230V is either phase+neutral or dual phases or a subset of triple phases (3x230V) or subset of 400V (3x phases + neutral).

And there's probably more lol. Most of the time in Belgium it's simple single phase+neutral.
 
Would a UPS Conditioner make up for this? Unless Isolation of the circuit.

I am not 5090 ing, Have 7900xtx with stock BIOS atm.
 
More examples of how important the CPU can be at 4K. Vex, a rando with a youtube channel, takes the time to test 9800X3D down to a 1600 with the 5090.


A few comments -

Stalker 2 is a terrible test case as the game is poorly optimized. Nvidia drivers are sus. I'd like to see the 7950X3D with the 5090 to test the hypothesis that cores and threads are why raptor slightly outperforms the 9800X3D with max RT/PT. Until that is determined, it is possible some of the cause is driver related. The HUB SS for the 5800X3D is outdated. It is faster than a stock 12900k on average now.

This is a relatively minor quibble especially in this context, but US 240V residential is still technically single-phase, it's just that the neutral is center-tapped out of the 240V secondary winding, which gives 120V from neutral to either of the two hot wires.
 
Just got one of these in my system, only played war of rights so I haven’t done much testing, but my bios was already updated so I just dropped it in. Very easy. Cinebench scores seemed to be in the ballpark. Excited to try out IL2 in VR and see if it helps any. Coming from a 7800x3d so it’s a total BS upgrade but whatever, I had the itch and most of my usual games are cpu bound sims. It seems to give my D15s a much harder workout than the 7800x3d did. Probably those bumped clocks now that cache is under the cores.
 
Today I see the 9800X3D available in multiple local shops in my EU country. It's not MSRP, still inflated by $50 (after taxes taken into account). If further shipments come in soon enough, price will eventually go down. Up until a few days ago one could barely find one.

AMD did say they will improve availability, so I'm cautiously optimistic.
 
I just noticed that Amazon (in the US) is again taking pre-orders for 9800x3d. Direct from Amazon. Shipping dates: Feb 27 - March 18.

Not long ago, Amazon stopped taking pre-orders when back orders stretched to the end of March. So it looks like Amazon got some shipments of CPUs from AMD to reduce their back orders.

Edit: at MSRP of $479

Stock continues to fail to keep up with demand at MSRP. Yet it retains the number 1 spot week after week. $550+ shipped from sketchy 3rd parties is the best you can do on Amazon U.S.

You can click on "Other Sellers", which is going to include option of placing your order with Amazon, at MSRP, which is backordered:

Sometimes Amazon lists estimated shipment date, but this time it does not show a date:

Edit: Looks like when there is no date, you can't place an order...
