eBay used Intel Arc B580 12GB consumer cards

USED / Pre-Owned, bare PCIe consumer card, as-is. $290.00 = Acer Nitro Intel Arc B580 12GB 'Used condition, Tested'. Observed used B580 band: $290.00-$499.00 (Sparkle 12GB $304.00, GUNNIR Index $319.00, ASRock Challenger $319.99, Intel Limited Edition $339.00, ASRock Steel Legend $450-$500). Captured 2026-10-03. No warranty. ASKING prices PERISHABLE-FIGURE STAMP (added 2026-10-04, uniform across data/supply/ so it is greppable). PRICE CLASS: ASKING price - the rate at which a seller advertises the item for sale, NOT a sold, completed or realised transaction price. 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: USED / Pre-Owned, bare PCIe consumer card, as-is READING RULE: No further perishable flag is published for this figure.

lead_time_weeks is null because no lead time applies: this is a secondary/auction market priced per listing. What a buyer faces is listing availability at the moment of purchase - the record's availability field is a snapshot of what a seller posted, not a schedulable delivery date - plus whatever shipping the listing states. An auction close date is not a lead time.

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.

The decision-relevant finding here is NEGATIVE and worth recording: the used market for B580 is thin (only 13 genuine B580 cards in the used-filtered result set) AND used is not cheaper than new. eBay's own price histogram for used B580 puts 7 items in $300-400, 4 in $400-500, 1 in $250-300 - and the same card sells NEW at $329.99 through Newegg. Buying used Intel consumer silicon is therefore a bad trade at these price points; see the Newegg Refreshed record for the refurb tier that actually undercuts new. Second observation: adjacent Arc parts show a coherent used ladder worth noting for inference builds - Arc Pro B70 32GB at $1,329.00, Arc Pro B50 16GB at $449.99-$690.00 (including one with a third-party single-slot cooler at $599.00/$690.00, which is the retrofit route to density), Arc B570 10GB at $244.99-$375.00, Arc A750 8GB at $170.00. The B50 16GB at $449.99-$500.00 is the genuinely interesting number: 16GB of GDDR6 workstation silicon for under the price of a used 4090. 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. Probe log in source spl-negative-no-oem-publishes-lead-time. EXPORT CONTROL (2026-10-04, mechanism-level; source spl-eccn-3a090-ccl): this is a CONSUMER discrete board (Intel Arc B580 class), which does not meet the ECCN 3A090.a 'total processing performance' >= 4800 or TPP >= 1600 / performance density >= 5.92 thresholds, so it is not an advanced-computing item and the case-by-case / D:5 licence regime does not attach to it; consumer parts of this class generally sit under ECCN 3A001 or are designated EAR99. Recorded FALSE for that reason, NOT because the part is unregulated - it remains under the EAR, subject to destination-country import rules and to screening of the consignee and its ultimate parent against the Entity, Unverified and MEU lists under 15 CFR part 744. This is the case that makes the point sharpest: an Intel Arc B580 and a datacentre accelerator can be sold by the same distributor on the same day under completely different regimes, so export status has to be recorded per part rather than inferred from vendor or channel.
