Not only does ATI not manufacture graphics cards, it doesn’t even manufacture GPUs. They all come from TSMC’s production lines. So according to your opinion, shouldn’t its GPUs have to be marked MADE BY TSMC? It is only responsible for developing and designing the specifications and parameters of a graphics card, including its core model, core frequency, video memory size, video memory frequency, number of power supply phases, output ports, PCB routing, etc., and strictly follows these specifications and parameters. Once manufactured, we call it a public version card.

Before a certain graphics card is put on the market in batches, some public version cards are often made for display or evaluation, and are also used as models by other graphics card manufacturers. The card in your picture should This is one of them. So although it may be produced by ATI's core partners, such as EVGA, Jingtai, Dylan, Sapphire, etc., since it is not mainly sold and circulated as a commodity, the manufacturer's name is not marked, but if you can get it If you look at these graphics cards and observe them with software such as GPU-Z, you will still see clues about the manufacturer.

Finally, how to distinguish public version cards is actually very simple. The first thing you need to understand is that non-public version cards may not have as good performance as public version cards. You can distinguish them through the Internet (for example, the official website ) Understand the parameters and appearance of the public version of a certain model - of course, this generally does not include the design of the radiator - and then compare it with other similar models, such as those with significantly shorter PCBs and lower or higher core/memory frequencies. , the number of power supply phases increases or decreases, external power supply is omitted, etc., it can be judged as a non-public board; generally speaking, when a graphics card is launched on the market, it is the first batch manufactured and sold by its core partners. Basically, they are all completely public designs.
