the 3D cache creates a direct IPC improvement
The IPC is the same as the 5800X:

Would need to check Cinebench R20 to be 100% sure though.
Single threaded performance is generally slightly worse, because of the lower clock rate.
Performance is generally only better in games.
If you can clock it at the same or higher clock speed, it should be a straightforward increase in performance.

Strange I'm sure I've read before of cache used to boost IPC but maybe once the cache gets big enough it has no effect on applications that don't need the cache so your impressions of IPC is that it's not changed
That's also why IPC should be measured over a suite of 30 or so software not just Cinebench, so the link you have provided is not a valid or final answer, it's a very simple one measure and falls well short of how AMD and Intel measures it

It's slower at number crunching generally, and most tasks too:

It really needs to be clocked at 4.7/4.8ghz on all cores to see an improvement in all tasks. I've heard this may be possible soon on many AMD boards, and has already been achieved on an MSI board.
Otherwise, it's only of benefit to gamers.

Not direct IPC improvement, what caches do is keep data close to CPU so it doesn't need to travel to RAM which is far away and IPC advantage vanish. 3D version can do same instruction per clock as regular version, but because it has much more cache, apps can storage more data in it so it is faster for apps to grab it. And because cache will play much bigger role in the future (RPL will also have increased cache), direct IPC to IPC comparasion is pointless, cpu is much more complex than that, and latency sensitives workloads like games depends on many things beside IPC. It is impressive to see that Zen 3d with 10-15% IPC deficit have similar performanse as ADL.

Which is why it's a dedicated gaming CPU; built, marketed and sold as such.
5800x3d created many content creators from competition company

Its only designed for gaming Dave you know that. Sounds like Zen 4 will beat Raptor Lake althogh it may be close and Zen 5 is shaping up to be a monster. I love your posts though Dave, never fail to make me chuckle
Indeed, carefully worded but throwing some shade. I'm betting 90%+ of buyers only tax their system when game playing. The rest make money at production and buy the best they can afford for that purpose.
Predictions based on preferences rarely go well! I've had products from most but prefer AMD where competitive. I bought a 2500K and a GTX 1070 because AMD weren't at the time. If AMD fall behind again I'd buy something else.

I find it strange that there isn't more excitement for Meteor Lake. I suppose people generally want the thing just around the corner, not necessarily the thing after that.
Everything I've heard from Intel sounds positive so far, and things appear to be going according to plan. Intel has a shot to take on Zen 4 with these CPUs, and potentially any improved versions like Zen 4 with additional cache.
Notice the difference in the quantity and detail of the information that Intel has released for Raptor Lake and Meteor Lake.
Judging by what they've said, which do you think they are more excited to release?
I get the impression that for Intel, the release of Sapphire Rapids (and possible Golden Cove enthusiast CPUs) is going to be a more important release than Raptor Lake.

AMD first has to beat Alder Lake (all around performance) with Zen4. Then There's Raptor Lake - which will presumably extend Intel's leadership 20-50% in most areas, due to 8 more cores, new architecture, new cache design etc.
As which will launch first, Raptor Lake or Zen4, that remains to be seen.
Remains to be seen , you made similar claims with Rocket Lake

To simplify this, Raptor Lake is not going to use a new architecture, Intel never claimed that would. Zen 3 > Zen 4 is by definition.
Intel has not mentioned 'Raptor Cove' at all. Even if this were the name, it would be inconsistent with how they name their microarchitectures. The architecture has a different name to the name of the generation.
Also, Intel does not design new desktop microarchitectures on the same node. The exception was Rocket Lake, which was kind of a desperate move, and came as a result of the many delays to their 10nm process technology for desktops.
It's notable that Rocket Lake's microarchitecture was called Cypress Cove (Not Rocket Cove, which sounds kind of silly).
Just like Zen 3 to Zen 3D with more cache is not a new CPU architecture. Raptor Lake appears to be Golden Cove with more cache and improved clock speeds. Additionally, 8 more E-Cores.

I'm hoping Raptor lake will be a big enough jump from the 9900k to warrant an upgrade. Been sat on the 9900k for a few years now and the urge to get an upgrade is pretty high!
I can see the jump in fps is pretty high on some games but more so at 1080p and some 1440p. 1440p is more relevant to me right now as im running that as my main (ultrawide) so really want this to be something i can upgrade to this year.

If you are only looking at another 3 year upgrade cycle, then Raptor lake would be OK, but anything longer than that then you are jumping on to a dead-end socket with no upgrades. Alternatively you've got socket AM5 coming out this year which 'could' last as long as AM4 has, and maybe have 4+ generations of CPU's available to you.
Yeah im also considering AMD but since the 3D chips have just released, its gonna be awhile till they have anything to respond to Raptor lake i think. But you're right, ideally i want a board i can keep reusing and not have to upgrade every single generation!
My last AMD chip was a Phenom X4 955!

Game genre matters. I only do simracing and getting a x3d because it’s almost damn near unbelievable the bump you get. It’s going to wipe the floor with my 9900k. Other genres might be less so.
I can then chill until MTL
But its investing in another motherboard thats pretty much EOL now unless you get a cheap used one to do you over for now. I can see the attraction though if the uplift is above and beyond what the 9900k can do now.
