Overclockers UK (UK enthusiast retailer) — Intel Arc B580 and RTX 5090 listings

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. Checked 2026-10-04 per source spl-negative-no-oem-publishes-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.

Complements the repo's overclockers-uk-4090-new-channel record, which covers the RTX 4090; this one covers Arc and the current GeForce flagship. All observations 2026-10-03, prices including VAT, and deliberately NOT converted to USD because no exchange rate was sourced. Arc B580: two listings visible at GBP 299.99 and GBP 319.99, both 'Out of Stock' - and note that GBP 299.99 is ABOVE the Micro Center in-store-pickup price of $309.99 for the same class of board, so the UK channel is not obviously cheaper even before shipping. RTX 5090: the only priced result was a Medion Erazer Beast 16 X1 laptop at GBP 3,899.99, cut from GBP 4,499.99, in stock - no discrete 5090 board was priced on this listing page, which is itself the finding, since it contrasts with US retail where discrete 5090 boards were priced but out of stock. A caution for anyone using this retailer as a price source: the laptop listing's own text says 'GeForce RTX 5090 GDDR7 24GB' while its title says 64GB, an internal inconsistency on the retailer's own page. Scan.co.uk was also probed for this region and refused the fetch (anti-bot), so no claim is made about it; the repo has no record covering the UK consumer channel beyond Overclockers UK and Geizhals. 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.
