Computing power of sapphire 574 graphics card

1. A card should be mine card! However, 256 bit wide, 8g video memory, should be quite good.

2. First, in a al card fight, the frequency of the high frequency card (580) will drop to the low frequency card (574) when the frequency is different, so the extra 20000 is contributed by 580. Just like if rtx2080ti and gtx650 can exchange fire, the result will be much lower than that of the single 2080 (the memory is also automatically reced)
Second, I don't know how to brush BIOS, but there are many tutorials on video websites such as station B.

3. The sapphire rx570 4G platinum version is quieter, and its performance is basically the same. However, the rx570 4G has been discontinued, and now it is a second-hand or mining card.

4. Not universal, not the same graphics card (except magic change random brush).

5. No, it's bad. First, you only have 4G video memory. Play a large game will explode video memory, the second point RX Series graphics card is not suitable for al graphics card. Because the power consumption is a little high
if you really want to, the graphics card must be a public graphics card. The public version graphics card is externally blown, and the fan is blown from the inside of the graphics card to the outside of the computer. Many non-public graphics cards are internally blown, and the fans are blown into the chassis. Two graphics cards will cause the total temperature of the graphics card to be very high, and the chassis will become very hot. So be sure if the public version graphics card remember

6. In terms of market positioning,
platinum Overseas Edition / gold poison atom

among them, platinum edition, Gold Edition and overseas edition are all procts of costdowm, which belong to the non-public edition of costdowm. Among them, the shrinkage of Platinum Edition is the most serious. The selling point of overseas edition is high frequency, but the materials used are not very good. Gold Edition is called small poison, and the materials used are between platinum edition and poison, But the frequency is not as good as that of the overseas version, so I put these two models to a higher level. Poison and atom are super public versions of costup, reflecting the strength of manufacturers, especially atom, which has not been listed in China at present. And poisons have a tendency to shrink now
V * * is AMD's professional graphics card, which is not compared with the market level graphics card

8. The main difference between these versions is the appearance and heat dissipation layout of the graphics card. The other is that the frequency of the graphics card may be slightly different. The rest are the same. Basically, there will be no difference in the performance and quality. You don't need to care. You really have to distinguish which one you buy, just do as I said. Identify the way to find the corresponding version of the appearance of the image and graphics card frequency, one by one can be compared.

10. There's no brand new one. Second hand, the previous generation's procts, although their strength is not bad, but compared with 7800 series, their power consumption and stability are not as good. To match E3, at least 7800 series procts are needed. The rich R 280-r 290 are the best partners
