Isn't this generation on a new AM5 socket, won't users need to upgrade their motherboards this generation

To clarify, this is a new platform, but they have committed to maintaining the AM5 socket (and supporting platform) through at least some future advancements, as they did with AM4 from Zen, Zen+, Zen 2 and Zen 3.

I think they only committed to 3 years of support, so not as good as AM4's 6(?) years

It's not that made up. 5950X used 120-140 W and I expect the 7950X to use 210-230 W. AMD said that the increased multicore performance comes from a higher power limit.

I’ve no doubt that the newer cpu will use more power, but the numbers are made up. They’re picked by the marketing department using a formula, and calling them “watts” to try to make them look like energy used or heat dissipated doesn’t make them real. They don’t correspond to numbers that you can actually measure in any way.

Whether or not what marketing calls it is accurate, Anandtech measure power draw in their reviews and (at least in this example) it's pretty well aligned with the advertised TDP/PPT: https://www.anandtech.com/show/15043/the-amd-ryzen-9-3950x-r...

One downside is that the TDP is almost doubled (170/~230 W vs 105/140 W for default/PPT) which may be a dealbreaker - certainly for my SFF system where I'm not sure I can cope with another 100W. These are limited by the socket really (AM4/AM5), but still it's nice to have that many threads in such a low power budget. I'm more curious to see what the 32-thread competition turns out to be in the same TDP bracket.

See the part of the article starting at “We’ll first start with iso (like-for-like) comparisons between Ryzen generations, with iso-power.” That shows “up to +37%” at 105W.

This is true, but there can be advantages to having 32 cores over 16, depending on your workload.

I’m not sure what you’re saying. Both the 5950X and the 7950X are 16 cores/32 threads.

Love that these include a basic igpu. Makes them much more viable for home server and low end desktops(when eventually discounted).

This makes these machines a lot more viable in the business and engineering world as well where CPU performance is desired but graphics is not. I've seen in the past AMD Zen machines paired with say a GT710 simply because it was the cheapest GPU option available that would allow for basic apps and drive two screens.

I am developer and this is my exact work setup

Yeah, but Intel has the advantage of providing vGPU support for their integrated graphics. I don't think there is anything really stopping AMD but wanting money.

Intel barely supports this anymore to me, and their SRIOV support has not been publicized anywhere from what I can see beyond a commit on GitHub. Furthermore, they are not including this on Arc dGPUs from my understanding, so I imagine Intel is moving this to datacentre GPUs only as well.

It used to be documented really well and Arch has a good entry about it too:

https://wiki.archlinux.org/title/Intel_GVT-g

Not sure if you were thinking of something else, but both NVIDIA and AMD could really approve in this regard. There is no reason to limit sharing your GPU across VMS except to primarily limit platforms.

From leaks so far, seems likely Intel's Raptor Lake CPUs like 13900k will be faster/cheaper, more details next month.

I'm sure Intel will make sure they will be cheaper. Even if they have to run at a loss in the short run. :)

AMD is giving Intel a bit of breathing space at the lower end of the product stack, the 7600X price/perf isn't that great when you factor in the requirement for DDR5 + new AM5 socket.

The thing i dislike most about the 7600X is it's switch from 65W RDP to 105W RDP, a 61% increase!

I wonder how this is going to look like in real world tests and if the motherboards will come as buggy as for 5XXX series, where it took almost a year to get a stable system.

I am feeling a bit sceptical, as I am not sure if these numbers are that impressing in comparison to previous gen. I am worried that AMD is starting to follow the Intel path. Hyping up the new line up, while selling essentially the same CPU with some cosmetic changes that in real world get you that 1% performance bump on a full moon.
