I speak the language of the videos used as a source, and if you ask me, it's perfectly accurate as it is, the only thing missing is the context from the country's market reality and I am all too happy to provide.
Cryptocurrency has basically completely subsided in our country - and miners have been getting increasingly bold and desperate to shift their expensive gear right as there's a strong rejection of used high-end GPUs specifically due to mining damage in our unfriendly climate. Hence, the whole situation at hand. It's greatly affected the used market - if I tried to sell my TUF OC 3090 today, I could ask *maybe* 5,999 BRL on it (somewhat north of $1000 USD), and it'd be a tough sell for what would be remarkably little money in Brazil (despite seeming like an astoundingly great deal for the seller from an American POV, a 3090 should be selling for $600 USD in America for most cases today) - I would be able to sell it because my card is pristine, factory-sealed with the warranty seal, and I have the box, receipt/proof of purchase, warranty card and everything intact for its new owner... after the MercadoLibre marketplace's commission I'd have maybe 5k on hand - this would not be enough to purchase an RTX 4070 Ti to replace it, these sell in the local market for around 7,299 to 8,499 (ROG Strix model, which is what i'd purchase at a minimum) - that's why *I*
gave up on selling my card.
This has been going on for some time - last year, Afox (which doesn't seem to hold an AMD AIB license
) got caught redhanded by the same media outlet selling Radeon RX 580s built out of recycled PCBs, most of them with RX 470/470D/570/580 2048SP (China-only SKUs) variants of Polaris dies, many of which had visible heat damage such as discolored substrate and/or yellowed epoxy due to being worked to the extreme for very prolonged periods of time - these are obviously being harvested from mining waste boards and slapped onto a low quality, recycle PCB, then sold full price through retail channels here. At the height of the GPU crisis, these RX 580s were actually being sold for almost $1000 USD locally. It actually resulted in some hysteria and even got the law involved - though they appear to have settled amicably. If you're interested:
The sources are trustworthy - TecLab is huge in Brazil - Ronaldo is a former overclocking champion employed by Galax and his channel is not any different in nature from, say, der8auer's. His channel has over 250,000 subscribers
. The other guy, Paulo Gomes (featured on Iskandar's channel), owns a high-end lab and is one of the two trustworthy technicians which can fix a graphics card in the country, the other being Burti from Harteck tecnologia. They're known to work with GPU companies' RMA departments.
I'm not against the idea of recycling, it could potentially reduce e-waste if done correctly and honestly (though I personally would never trust such a heavily used processor - I own an EVGA GTX 780 which was heavily used by its previous owner and it resets at random unless I heavily underclock it), but these could never, ever be sold in the retail channel as brand new products carrying AMD's brand. They should be cheap and sold on the down low, and that's something I respect on Aliexpress brands that sell exclusively through their stores such as Veineda - they never claimed to be all-new hardware or distribute them to the general retail channel in an attempt to pass as a licensed card intended for the end-user DIY market.
