No.I'm talking from a performance perspective, not an architecture prespective. In otherwords, is the performance difference between a 5800X3D compared to a 7800XD similar to a performance difference between a Pentium 133 compared to a Pentium 166 MMX?
None of that seems particularly applicable to what the OP is asking about.No.

Two totally different architectures. Similar to moving from any Intel prior to ADL and moving to ADL or RPL adds big bandwidth changes to the system components. While moving from a 5800 to a 7800 isn't quite as dramatic it's still significant.
The 7800 will open doors to current and future options that can take advantage of the increased bandwidth that's unlocked by PCIE gen 5 / DDR5. While DDR6 cost vs performance has been at a premium it's coming to parity slowly with DDR4.
Ultimately it depends on what you're going to want to do and whether to wait out the price reductions or jump in feet first.
And how does this help?None of that seems particularly applicable to what the OP is asking about.
Clarification if you want to answer the OP's question or just go off on a tangent.And how does this help?
When comparing going from a Ryzen 5800X3D to a Ryzen 7800X3D in terms of the Pentium (P5/P5-MMX) generation upgrade would it be like going from a Pentium 133 to a Pentium 166 MMX?
Not really. It's really hard to make that comparison.When comparing going from a Ryzen 5800X3D to a Ryzen 7800X3D in terms of the Pentium (P5/P5-MMX) generation upgrade would it be like going from a Pentium 133 to a Pentium 166 MMX?
Just one of the first results comparing the 2 CPU models. Hence the other link below it.Userbenchmark
Problem with that comparison is, MMX was the beginning of a new era of SIMD revolution that greatly sped up multimedia tasks. It gave way to AVX and AVX2 which are used heavily in a lot of 3D game engines. 7800X3D brings with it AVX-512 but it's not used in any game AFAIK. It is used in a PS3 emulator but even there, it's not as effective as Intel's AVX-512 because AMD chose the transistor efficient way of implementing it whereas Intel's implementation has always been power hungry and brute force, so much that the CPU heats up and it has to be downclocked to keep temps in check. Starting from Alder Lake, AVX-512 is gone on the Intel's side of the fence and may not return soon.Pentium 133 to a Pentium 166 MMX?
yeah and the post was tainted by it and all the credibility was lost.Just one of the first results comparing the 2 CPU models. Hence the other link below it.
The difference would be more like the difference between hasswell and broadwell, not actually but just as an comparison.I'm talking from a performance perspective, not an architecture prespective. In otherwords, is the performance difference between a 5800X3D compared to a 7800XD similar to a performance difference between a Pentium 133 compared to a Pentium 166 MMX?
Wrong. The internal design is quite different, including adding avx-512, and the clock speed is faster. They are really quite different, and the 7800x3d is much faster.The difference would be more like the difference between hasswell and broadwell, not actually but just as an comparison.
The performance of the cores are mostly the same but they gained a large cache.
The Pentium 5 is core which is what got me confused.Pentium (P5/P5-MMX) generation upgrade would it be like going from a Pentium 133 to a Pentium 166 MMX?
think thats a little low. My 5950x compared to 7950x or way more than 13%, more like 35-40%. Not to mention that in DC apps, avx-512 is used quite a bit, and the entire DC forum knows that.ACK EDIT..
Miss read.... (please ignore my initial comment. )
I think going from 133 to 166MMX was not even a debatable upgrade.
MMX bearly did anything the first gen, as no one knew how to use it properly.

MMX (instruction set) - Wikipedia
en.wikipedia.org
It was a failed tech Intel had, which got removed with the introduction of Core.
Later Intel Introduced SSE, but, even then, unless your applications specifically called for the instruction set, it was sort of pointless.
Its like how many debate if AVX-512 is even worth it.
Id say going from 5000 to 7000 is probably simular to going sandy bridge to Ivy Bridge., i think it was said to be about a 13% improvement.
So it is pretty simular to Haswell going to Broadwell, well depending on how you looked at it, the low was around 5% but people reported as much as 18% in some cases, which is why the x99 and broadwell lasted so long.
Nice summary. We really need more information from the OP, such as the primary use case (assume gaming since he has the X3D). However, for gaming, there may be little difference at all unless he has a top of the line video card.If the OP thinks that the 7800X3D may blow his mind, not really. It will give you like 30 to 40 fps extra in SOME games, but it's not gonna launch you into outer space with its speed. Well, maybe if you put it on a heavily CPU limited rocket engine that needs to complete some 3D operations during the countdown sequence and fails every time with a 13900KS coz the heat from that CPU causes a thermal runway condition leading to immediate explosion of the liquid rocket fuel mixture.
On average, it beats a 13900K at 1080p and it is almost as fast as a 13900K at 4K: https://www.techpowerup.com/review/amd-ryzen-7-7800x3d/27.html
Compared to a 5800X3D, about 20% faster at 1080p and 5% faster at 4K. But look at individual game results if you are interested in a particular game. I think you would be spending a lot more money for not that much performance improvement if you upgrade from a 5800X3D.
Yeah, if he has a 4090, that card needs a CPU from the future. It's badly CPU limited even at higher resolutions, thanks in no small part to Nvidia's drivers.unless he has a top of the line video card.

that's one way to describe haswell !The difference would be more like the difference between hasswell and broadwell, not actually but just as an comparison.
