乐扩 lekuo launched another big sb (south bridge) b650 aic, priced at 499rmb/75usd. they flipped the m.2 slots so that the front m.2 slots are now gen3x2, while the back slots are gen4x4. they also removed the sata ports and the usb type-a ports.
you may wonder why. they did all ibility, including rj45 ports, optical/fiber ports, sata ports, oulick etc via m.2 modules.
the lekuo m.2 modules are priced at 299rmb/45usd:
- one rj45 10g ports (realtek rtl8127at)
- one optical/fiber 10g port (realtek rtl8127atf)

the lekuo gen4x4 64gbps aic that uses the amd prom21 b650 chipset, lekuo southbridge max (PB65MX3), is ready, but the supply is extremely limited.
- no driver installation required
- no mobo bifurcation required
- plug and play
- support w10 / w11 / mac os / linux
- 4*m.2 (x4 / 4*sataiii / 2*usb-a 10g / 1*usb-c 10g / 1*usb-c 20g
- pcie 6pin for usb power
it is priced at 599rmb/~90usd for the china market and 129usd globally.
six usb2 are wasted:(((
lekuo explained why it was delayed for three months and why availability remains extremely limited (30pcs/day):

I need to play Freespace and Freespace 2 someday.
I forget, which one of them had in the EULA a clause giving people full permission to copy and distribute the game? Or was that an urban legend?

If only I could force Win98/ME to run entirely in my 5500X3D's L3 cache. Looks like it's already possible to boot it off 3DXpoint(Optane) NVMe-
Windows 98 / ME QuickInstall v1.1.0 is RELEASED!
- Lots of driver library updates
- Integrated NTFS support
- Experimental HD Audio driver
- Voodoo 1/2 patches for fast PCs
- Patched NDIS2 connection stalls
- Show device ID in hardware installers

Amazing.
Those still strangleheld to AM4, see AMD Radeon punching well above their weight vs. GeForce.
Given the CPU and PCIe bottleneck of the Cezanne 5500, Navi48 cards are meeting and beating GB203 and even GB202 cards. -especially, at 1% lows.
Great review, @hardwarecanucks

I tested the cheapest Ryzen CPU on EVERY modern GPU & NVIDIA cards have a problem...

What in the world?! Ryzen 5 5500F is a Cezanne-derivative same as the Ryzen 5 5500.
The 5500F lists 3.0Ghz base, 4.4Ghz boost, 65W TDP
The 5500 lists 3.6Ghz base, 4.2Ghz boost, 65W TDP
They are different SKUs with different clock profiles but otherwise nearly-identical silicon.

Introducing the AMD Ryzen™ 5 5500F and AMD Ryzen™ 5 7500, built to deliver practical value for 1080p gaming. From affordable AM4 upgrades to entry-level AM5 builds, both processors offer a solid foundation for your next system.

Correction:
According to WCCFtech's research, 5500F is indeed a Vermeer MCM CPU with bad cache. @SaltMineRanch is apparently correct, I am incorrect.

Yeah, my 111 tok/s dual-R9700 post may have underestimated these GPUs.
I found another builder with 2× Radeon AI PRO R9700s documented this progression running Qwen3.8-27B 👇
llama.cpp default:
🐌 19.2 tok/s
llama.cpp tuned for gfx1201 + tensor split:
⚡ 29.7 tok/s
vLLM .9 tok/s
Same pair of GPUs.
And the latest Radiance benchmarks are now reporting ...
🧠 183.1 tok/s weighted single-stream
💻 188.8 tok/s code
🛠️ 218.8 tok/s file editing
📐 243.7 tok/s math
📄 249.4 tok/s JSON
And up to 523.5 aggregate tok/s at concurrency 8.
AMD might have a low-key story with the software, finally starting to use hardware to its fullest. 👀

🤯 This entire 64GB AMD AI workstation cost its builder LESS than a single RTX 5090 and Qwen3.8-27B is hitting 111 tok/s.
This is the kind of rig that makes me want to build it because RTX 5090s are so expensive.
Setup 👇
🟠 2× Radeon AI PRO R9700 32GB
💾 64GB total dedicated GB DDR5
🔌 PCIe 5.0 x8 per GPU
⚡ vLLM Radiance + TP2 + MTP
Running Qwen3.8-27B Quark AWQ MXFP4 ...
🚀 111.4 tok/s median decode
⚡ 4,224–4,410 tok/s prefill
⏱️ 81ms TTFT
📚 131K server context
Native FP8 still managed 87.6 tps
🎮 RTX 5090 → 32GB VRAM
🟠 2× R9700 → 64GB VRAM
The builder says the entire machine cost ~€4,000, more than €1,000 less than a single RTX 5090 in his market.
So for less money, he ended up with 2× the VRAM + 111 tok/s on Qwen3.8-27B. 🔥
