Use the evidence behind a listing, not its headline price alone. Here is what we record, what our checks can establish and what remains for the buyer to verify.
What we check
We record the exact hardware family, memory architecture and capacity, asking price, shipping when known, condition, seller, listing source, and the time of the latest check or search sighting. A marketplace check is not a physical inspection, a seller endorsement, or a guarantee that the offer is still available.
Freshness and availability
- Checked means the listing page was queried and appeared available at that time.
- Seen in search means the offer appeared in marketplace discovery results; it is not an availability confirmation.
- Availability unconfirmed is the default when we lack a recent direct check.
- Active listings older than 24 hours since their last check are candidates for rechecking. Expired or sold listings may remain as historical evidence, but they lose their purchase action.
Prices, shipping and availability can change between checks. The seller page is authoritative at purchase time.
What the board count means
The matching-offer count can combine two evidence classes: saved updater records whose inventory status was reported at the last refresh, and recent marketplace search sightings whose availability is unconfirmed. A search sighting expands discovery, but it is not promoted to a checked or reported-in-stock listing without stronger evidence. The total count therefore describes rows that match the current filters—not a count of verified inventory.
- Reported in stock at last check means the saved source reported inventory during its latest updater refresh; it can still change before purchase.
- Availability unconfirmed means the row came from discovery evidence without a recent full-detail availability check.
- Withheld means a candidate is excluded from the visible rows because availability, hardware identity or condition is not sufficiently clear.
Search snapshots are retained for no more than 24 hours on the current board. Unknown shipping remains unknown, so the board does not present an optimistic delivered total. Open the current screened market or save private return criteria and follow RSS.
Deduplication
One seller listing should appear once in the current board, even when it is discovered through more than one query or hardware page. We match on marketplace identity where available and review likely duplicates created by title changes or tracking parameters. Different sellers, configurations, conditions or bundle contents are not duplicates merely because their titles are similar.
Delivered cost, not an optimistic subtotal
When both item price and shipping are known, the board can compare their sum. Unknown shipping remains unknown; it is never treated as free. Tax, duties, local pickup costs, platform fees and required system upgrades are excluded unless explicitly stated. Offers in different currencies are not silently converted.
Seller and listing risk signals
HighVRAM does not certify sellers. Buyers should verify seller history, return terms, warranty transferability, photographs, serial or model identity, accessories, damage disclosures and whether a card was modified, mined on, water-cooled or sold for parts. A low price never overrides a material identity, condition or seller-risk concern.
Compare like with like
Dedicated VRAM, unified memory, and system RAM are identified separately. A discrete GPU and a complete computer are different purchase classes. Price per GB is a capacity comparison, not a performance score. Software compatibility, precision support, memory bandwidth, compute throughput, power, cooling, noise, expansion, warranty and the rest of the system also matter.
Rules for value claims
We only call an offer a strong value when the comparison has a named peer group and enough comparable data. At minimum, the hardware identity, usable memory class, condition, asking price and shipping treatment must be clear. Any value assessment must state whether it is based on capacity, measured performance, total-system cost or another defined metric. Missing values remain unknown rather than being estimated to improve a ranking.
A value assessment is not permitted when the listing may describe a different product, a parts-only item, an incomplete system, a materially damaged device, or a price whose required shipping is unknown and could change the conclusion.
Benchmarks and performance evidence
Performance claims link to their source and stay attached to the reported model, quantization, runtime, context, batch or concurrency settings, and timing definition when those details are available. Results from different test shapes are not collapsed into a universal hardware ranking. Unreported settings remain unreported.
Editorial independence and corrections
Affiliate and sponsored status are displayed separately from editorial judgments. Paid placements do not receive a ranking boost. We distinguish source-reported research from hands-on testing and link to supporting evidence. Material corrections should identify the affected offer or record, the source evidence and the requested change.
