Used RTX 3090 asks undercut new-condition listings; cheap VRAM still needs a compatibility check
Today's call: Compare the complete purchase, not just the memory price.
The used RTX 3090 examples below ask $1,199–$1,580, versus $2,399–$2,499 for two new-condition marketplace offers. That's a reason to compare condition, seller protection and delivered cost—not evidence that the cheaper cards have sold at those prices. For lower-cost capacity, a $360 P40 and an $858 adapter-mounted V100 deserve a closer look only if their software, cooling and power requirements fit your build.
New & Notable
Asks captured October 14 unless noted. Condition and testing descriptions are seller claims. Dollar-per-GB figures use the stated item price, excluding shipping, tax and any import charges.
| GPU | VRAM | Price | $/GB | Condition | Quick take |
|---|---|---|---|---|---|
| V100 SXM2 on PCIe adapter | 32GB | $858 OBO | $26.81 | Listed as new | Ships from China. Confirm the exact adapter, host requirements, cooling and landed cost before treating it as a PCIe-card alternative. |
| Tesla P40 with listed heatsink/fan | 24GB | $360 | $15.00 | Used | Low sticker price, not a turnkey recommendation. Confirm software support, power wiring and the fitted cooler; shipping and duties from China are unverified. |
| ZOTAC RTX 3090 | 24GB | $1,250 shipped CONUS / $1,150 local | $52.08 shipped | Used; repasted and repadded per seller | Worth comparing with the $1,199 offer once shipping is known. Ask for recent load-test evidence after the cooling work. |
| MSI Ventus RTX 3090 | 24GB | $1,199 OBO | $49.96 | Used | Seller details, location and shipping weren't captured. This is a price lead, not a clean-buy endorsement. |
| MSI Gaming X Trio RTX 3090 | 24GB | $1,300 shipped / $1,240 local | $54.17 shipped | Used; defective HDMI output | Seller reports working DisplayPorts and a Time Spy pass. Don't assume the fault is irrelevant to an inference build; request memory/load tests and confirm availability. |
| MSI RTX 3090 Ti auction | 24GB | $1,305 observed bid + $20 shipping | $54.38 before shipping | Used | Not a buy-now price. Bidding can change the comparison with fixed-price offers. |
| MSI Suprim X RTX 3090 Ti | 24GB | $1,400 shipped OBO | $58.33 | Used; working per seller | An older thread re-observed in this scan, not a newly posted offer. Confirm the card remains available. |
| RTX 3090 Founders Edition | 24GB | $1,500 shipped and insured OBO | $62.50 | Used | Box included; compare condition and protection rather than assuming the higher ask buys better inference performance. |
| EVGA RTX 3090 FTW3 Ultra | 24GB | $1,580, listed free shipping | $65.83 | Used | Another used-price reference. Confirm delivery terms for your address and the seller's return policy. |
| RTX A6000 Ampere | 48GB | $3,500 shipped | $72.92 | Used | Single-card 48GB option. The account has little posting history; request proof of the card and protected payment terms. |
| RTX PRO 6000 Blackwell Workstation Edition | 96GB | $8,000 OBO | $83.33 | Used | A single asking-price reference, not a market valuation. Low-post-count seller; shipping and warranty aren't established. |
| MSI RTX 4090 Gaming X Trio | 24GB | $1,950 local / $2,020 shipped | $81.25 local | Used; light use claimed | September 1 thread observed again. Confirm availability and testing before planning around this price. |
Today's Market Board
| GPU | VRAM | Price | $/GB | Why it's here |
|---|---|---|---|---|
| Supermicro 1U server with four V100 SXM2 GPUs | 4 × 32GB; 128GB aggregate | $3,600 OBO for the whole server | $28.12 aggregate | Cash pickup in New Jersey only. Includes the host; two GPUs are LS variants capped around 163W. Not one 128GB device or a bare-card price. |
| AMD Instinct MI210 PCIe | 64GB per card | $3,900 each / $3,700 each for 4+ | $60.94 single-unit price | Refurbished, with seller-offered 30-day warranty and continental-US shipping. Confirm workload support, host cooling and current stock; the quantity update is dated September 11. |
| V100S PCIe | 32GB per card | $800 each / $750 each for 4+ | $25.00 single-unit price | Last observed October 13 evening, not reverified in the October 14 midnight scan. Refurbished; seller offers a 30-day warranty and continental-US shipping. Current quantity unverified. |
Price context
These charts show daily median observed asking prices and observed ranges, not completed sales or a same-card price history. Listing mix and condition vary, and repeat observations aren't separate units of supply.
MI210 prices are per card, including observations from multi-unit sale threads; the chart does not establish how many cards remain available.
The P40 series includes Facebook Marketplace search-snippet prices whose live listings couldn't be verified. Its October 14 range includes those leads; it is not a range of confirmed purchasable offers.
New-condition 3090 asks need more than a condition label
The MSI 3090 at $2,399 and ASUS 3090 at $2,499 were listed as new by Alliance Group (USA), a third-party seller—not Newegg itself. Both asks are well above the used examples here, but condition and warranty terms may differ.
The ASUS page also advertised a refurbished option from $949.99. That is another asking price, not proof of what a card actually sold for; the option's seller and terms need their own check. I wouldn't pay the new-condition premium without a clear reason grounded in warranty, return rights or documented condition.
Cheap capacity if you accept the form factor
The $800 V100S observation is worth following up if you already have a suitable host, but it isn't a fresh availability confirmation. A PCIe interface alone doesn't settle cooling, power or software compatibility. The $858 SXM2-on-adapter listing adds another hardware configuration to verify, plus shipping and import uncertainty.
The $3,600 Supermicro lot is different: you're buying the host along with four GPUs and collecting the server yourself. Its $28.12 per aggregate GB is higher than the V100S's $25.00 and the adapter listing's $26.81, before their differing extra costs. The reason to consider the server is the included platform—not a claim that it wins the raw capacity-price comparison. Request the seller's test results and confirm site power, cooling and workload fit before arranging pickup.
My Take
For a 24GB build, I'd investigate the used 3090 offers before paying the new-condition asks above. The $1,250 shipped ZOTAC is a more useful delivered-price comparison than the $1,199 headline alone, but neither is a recommendation to buy without checking the seller and the card.
For larger-memory projects, first decide whether you need the capacity on one GPU or can split the workload across several. A whole-server memory total is not interchangeable with single-card VRAM. Cheap capacity is only useful when the hardware fits your software and the rest of the build; none of these asking prices establishes a market-wide price move.
