Xiaomi MiMo V2.5 on 2x DGX Spark: 32 tok/s single, 184 tok/s at 8 concurrent, 97.8 tool-quality (measured)
MiMo V2.5 is Xiaomi's 310B/15B-active omnimodal MoE, MIT open weights, that reached ~13% of OpenRouter traffic in May. We ran the NVFP4 build on our 2x DGX Spark cluster: ~32 tok/s single-stream, 184 tok/s at 8 concurrent, 1M context, 97.8/100 on a 69-scenario tool eval. Slower on deep context and concurrency.

DeepSeek V4 Flash on 2x DGX Spark: 61 tok/s single, 261 tok/s at 16 concurrent (DSpark spec-decode, decode-only)
Reviews stop at ~40 tok/s for DeepSeek V4 Flash on a dual DGX Spark. On our 2-node cluster the DeepSeek-V4-Flash-DSpark checkpoint lifts single-stream decode to 61 tok/s and 261 tok/s at 16 concurrent. The lever is speculative decoding, not FP4, and the kernel still crashes under concurrent long context.

DGX Spark runs Qwen3.5-122B at 59 tok/s general and 81 on agent traffic, with speculative decoding (not NVFP4)
On a single DGX Spark, Qwen3.5-122B-A10B with DFlash block-speculative decoding runs about 59 tok/s on general decode and about 81 tok/s on real agent and tool-call traffic. For agentic work the lever is speculative decoding, not the stock low-50s decode reviews quote, and not NVFP4 (no measured win on this model).

NVFP4 + Qwen 3.6 35B-A3B on DGX Spark: 97 tok/s single, 322 tok/s at 8 concurrent (decode-only)
NVIDIA's official NVFP4 checkpoint of Qwen 3.6 35B-A3B (May 28). On a DGX Spark running the technigmaai/dgx-spark recipe we measured 97 tok/s single-stream and 322 tok/s aggregate at 8 concurrent with prefix-cached prefill (42 tok/s per stream). Community MTP-3 sweet spot adds another lift on FP8.

DRAM shortage: RTX 5090 +29%, 4090 +28%, used 3090 +17%, GB10 mini-PCs +34% in May
The DDR5 / GDDR6 / GDDR7 contract spike that started in March is now visible at retail across the LLM-rig segment. 16 builds repriced this week — RTX 5090 cards now $3,658+ over the $1,999 MSRP, 4090 partner stock dried up, used 3090 / AMD W7900 / GB10 mini-PCs all moved between +6% and +34%.

GB10 mini-PC pricing diverges: DGX Spark drops 15% in the UK, MSI EdgeXpert holds at €4,700 in France
CyberPowerPC UK cut the NVIDIA DGX Spark 128 GB from £4,699 to £3,999 (−14.9%) in mid-May; LDLC France still lists the equivalent MSI EdgeXpert MS-C931 (4 TB) at €4,699.95. UK buyers are now meaningfully cheaper than EU on the same GB10 silicon.
