Looks like the Zen architecture is finally hitting its limitations. Intel’s Raptor Lake is going to be released with another 15% single threaded IPC increase over Alder Lake along with a 40% increase in multi-core performance. It’s insane how Intel was on 14nm for 6 years and AMD was only able to beat them for one generation due to TSMC’s 7nm process.

Is that in the Chipset? Or a dedicated WiFi chip on the mainboard? Anything in the kernel yet?

No, I got that But if you're also using external GPU what's the tool to control which GPU is used?

The first one is integrated on cpu, the second is a discrete PCI express GPU.
The same can be made with command line property of steam games.
This led me to reduce idle power consumption from 60 w to 40. I just use the discrete gpu for playing games or other tasks that makes sense.

Didn't they do anything besides porting zen 3 to 5nm and doubling the L2?
I suspect they're comparing against the "3D" parts that were meant to be an in-house technology demonstrator/test parts, but got so much attention they had to make them into real products. Based on what they showed the initial Zen4 parts aren't going to have it, but they will be extensively compared to them and hence would/will face a lot of criticism if it's just compared to the regular Ryzen 5000-series.

IGPU is on the IO die, where also the PCIE controller resides. So it has a very fast pathway to use the iGPU for say video decoding and dma the output to a discrete gpu. There will be your usual bios toggles, but I expect it to be automatic - it either detects a gpu on the slot market as "first" or primary, or falls back to the igpu. I don't expect that anyone would want to disable the igpu even with a discrete gpu, because it will likely contain accelerator circuitry that even if nowhere nearly as "fast" as a fat gpu, will have unparalleled latency as it basically resides on the hardware system agent level. That's amd's whole argumentation in favor of making the tiny igpu "a guarantee" across its entire product range, well that and counting each those as a gpu unit to improve its overall graphics market share, in which intel's been eclipsing both amd and nvidia due to having igpus in every consumer cpu.

Originally posted by Drago View PostI am wondering if there is any plans for a beefier APUs, where single compute chiplet is replaced with GPU chiplet?
Limiting CPU to 8C/16T, but still enough.

Originally posted by Slartifartblast View PostInteresting, I wonder if the desktop 7000 series will feature a reasonable amount of CUs for the IGP as there was a rather wide disappointing disparity in the 6000 mobile series of either 6 or 12 CUs. DDR5 memory is still painfully expensive though.
It would be funny if harvesting all the usable parts from an OEM PC was cheaper than paying extra for DDR5, but we are only looking at +$100 for 32 GB DDR5, I think. It's a cost that can be tolerated if you want to be an early adopter.

Originally posted by agurenko View PostGenerally looking very good, but I'm torn about the integrated GPU. How does switching between iGPU and external GPU is done on AMD side? I guess as a good part, that would allow easy external GPU VM pass-through.
