Surprisingly not that much to be excited about IMO. AMD isn't using TSMC's latest node and the CPUs only officially support DDR5 speeds up to 5600MHz (yes, I know that you can use faster RAM). The CPUs are also using the previous-gen graphics architecture, RDNA2.

TBH, CPUs nowadays are mostly good enough for the consumer, even at mid or low tiers.

It's the GPUs that are just getting increasing inaccessible, price wise.

It's because x86 chips are no longer leading in the client. ARM chips are. Specifically, Apple chips. Though Qualcomm has huge potential leapfrog AMD/Intel chips in a few generations too.

[If you're a laptop user, scroll down the thread for laptop Rust compile times, M3 Pro looks great]

You're misguided.

Apple has excellent Notebook CPUs. Apple has great IPC. But AMD and Intel have easily faster CPUs.

Blender Benchmark

      AMD Ryzen 9 7950X (16 core)         560.8
      Apple M2 Ultra (24 cores)           501.82
      Apple M3 Max (12 cores)             408.27
      Apple M3 Pro                        226.46
      Apple M3                            160.58
It depends on what you're doing.

I'm a software developer using a compiler that 100%s all cores. I like fast multicore.

      Apple Mac Pro, 64gb, M2 Ultra, $7000
      Apple Mac mini, 32gb, M2 Pro, 2TB SSD, $2600
[Edit2] Compare to: 7950x is $500 and a very fast SSD is $400, fast 64gb is $200, very good board is $400 so I get a very fast dev machine for ~$1700 (0,329 p/$ vs. mini 0,077 p/$)

[Edit] Made a c&p mistake, the mini has no ultra.

Until ARM has a proper UEFI support, it's not a practical desktop/server with a few notable exceptions (Mac, Raspberry Pi) and only because there's so much support from the respective vendors. I know that there's some work happening about UEFI+ARM ( https://developer.arm.com/Architectures/Unified%20Extensible... ), but its support is very rare. The only example I can recall is Ampere Altra: https://www.jeffgeerling.c…

It's like I keep saying: the first Chinese manufacturer to churn out cheap SBCs with ServerReady support will make a killing as a true Pi killer. Anyone? Anyone? Pine64? Pine64?

How are the 24x PCIe 5.0 lanes (~90GB/s) of the 9950X allocated?

The article makes it appear as:

* 16x PCIe 5.0 lanes for "graphics use" connected directly to the 9950X (~63GB/s).

* 1x PCIe 5.0 lane for an M.2 port connected directly to the 9950X (~4GB/s). Motherboard manufacturers seemingly could repurpose "graphics use" PCIe 5.0 lanes for additional M.2 ports.

* 7x PCIe 5.0 lanes connected to the X870E chipset (~28GB/s). Used as follows:

  * 4x USB 4.0 ports connected to the X870E chipset (~8GB/s).

  * 4x PCIe 4.0 ports connected to the X870E chipset (~8GB/s).

  * 4x PCIe 3.0 ports connected to the X870E chipset (~4GB/s).

  * 8x SATA 3.0 ports connected to the X870E chipset (some >~2.4GB/s part of ~8GB/s shared with WiFi 7).

  * WiFi 7 connected to the X870E chipset (some >~1GB/s part of ~8GB/s shared with 8x SATA 3.0 ports).

I think that decision is ultimately made by the mainboard vendor.
