Micro Center (US big-box, in-store pickup)

ASRock Intel Arc B580 Challenger OC 12GB bare card, Micro Center in-store price, observed 2026-10-03, marked 'Available for In-Store Pickup Only'. Peer B580 SKUs: five refurbished boards at $179.99 each. PRICE CLASS: this is an ASKING price captured from a live listing or product page, i.e. the price at which a seller advertises the part for sale right now. It is NOT a sold/completed transaction price, NOT an auction result and NOT a dealer cost. A realised price on the same day would generally be lower, and for used or refurbished parts the gap between ask and realised is typically wide PERISHABLE-FIGURE STAMP (added 2026-10-04, uniform across data/supply/ so it is greppable). PRICE CLASS: ASKING price captured from a live listing or product page - the price at which a seller advertises the item right now.

OBSERVED: 2026-10-03 RE-VERIFY BY: 2027-01-04 - the repo's quarterly re-verification bar. After that date this figure is presumed drifted and must be re-checked against its source before it is quoted again. A price without its observation date is noise; this stamp exists so a reader can tell a fresh figure from a stale one without reading prose. UNIT: ASRock Intel Arc B580 Challenger OC 12GB bare card, Micro Center in-store price, observed 2026-10-03, marked 'Available for In-Store Pickup Only' READING RULE: No further perishable flag is published for this figure.

NEGATIVE, DELIBERATELY NOT STRUCTURAL: no lead time in weeks is printed for these SKUs. It is not that no vendor in the chain publishes one - CDW does, and it is recorded on cdw-enterprise as 'published' - but this channel routes to 'request a quote' or shows a stock count instead, so the number exists elsewhere in the market and is not surfaced here.

EAR 3A001 or EAR99 (below the 3A090.a TPP / performance-density thresholds) + EAR 744.23 (Entity List) + EAR 744.6 (Unverified / MEU lists)

MECHANISM: the part falls BELOW the ECCN 3A090.a/.b TPP and performance-density thresholds, so the advanced-computing licence regime, its case-by-case China/Macau carve-out and its D:5 screening do NOT attach. What remains is the general EAR plus destination-country import rules and screening of the consignee and its ultimate parent against the Entity, Unverified and MEU lists. NO LICENCE REQUIRED for the sale itself; the screening is a party-listing check, not a performance-threshold check. The binding ECCN determination for any specific part is the exporter's own classification, not this record.

Every GPU here is 'Available for In-Store Pickup Only' - there is no shipped channel, so this is not usable for remote buyers and stock is per-store. Two useful signals from one snapshot: refurbished Arc B580 boards sell at $179.99 against $309.99 for a new ASRock Challenger, a 42% discount that makes a used B580 a genuinely rational local-inference purchase; and the Arc Pro B60 24GB sits at $649.99 (down from $799.99) with the Arc Pro B70 32GB at $1,599.99. RTX PRO 6000 Blackwell is stocked in store at $15,899.99-$16,999.99, below both B&H and CDW, and a Threadripper PRO 9975WX system with an RTX PRO 6000 Max-Q is listed at $29,999.99. EXPORT CONTROL (2026-10-04, mechanism-level; source spl-eccn-3a090-ccl): consumer gaming cards of this generation generally do NOT meet the 3A090.a TPP/performance-density parameters and fall under ECCN 3A001 or are designated EAR99, i.e. the advanced-computing licence regime with its case-by-case and D:5 screening does not attach to them. This is exactly what makes export status a PER-PART property rather than a per-vendor one: a GeForce RTX 5090 and a datacenter/professional part from the same vendor and the same process generation can carry entirely different control status. Recorded as false for that reason, NOT because the part is unregulated - it remains subject to the EAR generally, to destination-country import rules, and to screening of the consignee and its ultimate parent against the Entity, Unverified and MEU lists (15 CFR part 744). The binding ECCN determination for any specific SKU is the exporter's own classification, which no public vendor page states. LEAD TIME: null, and deliberately so. A marketplace or big-box reseller publishes STOCK STATE, not a lead time - where this record shows in-stock that means the listing was available on the observation date, and where it shows backorder no week window is published at all. Converting one into the other would be an invention. The one exception in the whole chain is CDW, which does print windows (source spl-cdw-published-lead-times-gpu-2026-10); note that even there the scarcest SKUs - the RTX PRO 6000 96GB cards and DGX Spark - read 'Item Backordered' with NO estimate, so scarcity and lead time are inversely related in what distributors actually publish.

This record's price (309.99) is for ONE item: an ASRock Intel Arc B580 Challenger OC 12GB bare card. The record previously also listed intel-arc-pro-b60 and nvidia-rtx-pro-6000-blackwell in accelerator_ids, because that listing page carries those parts too. That let the value-analysis join pair a $310 price with a 96GB RTX PRO 6000 Blackwell decode benchmark and produce a "5636 tok/s per $1000" figure that is off by roughly 60x: it was the price of a 12GB card divided by the throughput of a 600W 96GB workstation card. The join rule this broke: a supply record's price attaches to the item its price_basis names, not to every accelerator mentioned on the page. Where a listing page covers several parts, the record must either carry one accelerator_id and a price_basis that names that part, or carry per-part prices. The B580 stays because it is the priced part.
