Benchmark Schema

Each line in data/results.jsonl is one benchmark measurement row.

JSONL files do not include a header row. The field contract below is the header. Run python validate.py data/results.jsonl before submitting changes.

Required Fields

Field	Type	Rule
variant	string	enum: desktop, sff, laptop
vram_gb	number	required metadata; never identifies desktop vs SFF by itself
memory_type	string	enum: gddr7, gddr6
bus_width_bit	integer	memory bus width in bits
bandwidth_gbps	number	primary desktop/SFF variant discriminator
tdp_w	number	per-card canonical/reference total board power for the variant
pcie_lanes	integer	per-card PCIe link width for the variant, e.g. 16 for x16
gpu_count	integer	one or more GPUs used for the run
model	string	model or run label
params_b	number	parameter count in billions
quant	string	enum below
backend	string	enum below
backend_version	string	commit, version, or digest
driver_version	string	NVIDIA driver version
os	string	OS and version
context_len	integer	prompt/context target for the run
concurrency	integer	simultaneous streams represented by the row
tok_s_prefill	number	prefill or prompt-processing tokens per second
tok_s_decode	number	decode/generation tokens per second
vram_used_gb	number	peak VRAM used by the measured run
power_w	number	board power during measured window
thinking	string	enum: on, off, n/a
source	string	must be owner-measured
submitter	string	person or organization submitting
date	string	ISO date, YYYY-MM-DD
notes	string	provenance and measurement caveats

Variant Sanity Checks

The validator identifies the physical desktop/SFF variant from bandwidth, TDP, and PCIe lanes. VRAM, memory type, and bus width are recorded metadata, but they do not separate desktop from SFF because both are 24 GB GDDR7 ECC on a 192-bit bus.

The validator enforces these current public specs:

Variant	vram_gb	memory_type	bus_width_bit	bandwidth_gbps	tdp_w	pcie_lanes
desktop	24	gddr7	192	672	140	16
sff	24	gddr7	192	432	70	8
laptop	16	gddr7	256	896	OEM-dependent	OEM-dependent

For laptop rows, tdp_w and pcie_lanes still must be reported from the owner or OEM configuration, but they are not hard-coded by the validator because mobile implementations vary.

SFF source: NVIDIA RTX PRO 4000 Blackwell SFF Edition datasheet, workstation-datasheet-blackwell-rtx-pro-4000-sff-nvidia-us-4016700.pdf. It lists 24 GB GDDR7 ECC, 192-bit, 432 GB/s, PCIe 5.0 x8, 70 W, and dual-slot half-height form factor.
