Dylan hd7990

1. Search Zotero's browser plug-in on the Internet, Download (decompress) and get a CRX file. You can decompress it with compression software to view the source code, including JSON, HTML, JS and other files. Equivalent to a web control, but this installation in the browser may work on all the web pages you browse. However, it's hard to understand the source code directly. I'm also learning how to make browser plug-ins recently. I hope you can share some good learning methods~

2. Hello, you can go to AISI to have a look. If you break the prison, you can go to PP assistant or dangle to have a look.
hope to adopt it, thank you

3. Devil 13. The 7990 was made by Dylan before the release of the public 7990, so its performance is not as good as that of the public 7990

5. First of all, if you don't install x, 3930k CPU is enough
then it's a question whether you want to overclocking. If you don't overclocking, high-end air cooling is OK (water cooling is OK). Overclocking must be water-cooled
if you want to use the motherboard, you can use ASUS r4e, memory, pirate ship 4G * 4 four channel package (16g must be enough)
Seagate 2T hard disk + 128G SSD as C disk. However, there must be more budget in this way
CPU i7 3930k 3700
motherboard ASUS r4e 3600
Corsair 4G * 4 2133mhz 1900
Dylan hd7990 5000
Corsair hx750 gold medal power 1100
radiator Corsair H90 water cooling radiator 800
Seagate 2T 550
mguang M4 128G 750
if you add the display 2000, it's just about 20000. If you have more, you can consider two hd7990 (the power supply should be added to 900 watts) or i7 3970x

R9 290 is the most cost-effective, which is not much different from 290x:

Dylan R9 290 cool energy 4G DC ￥ 2088

but the power consumption of a card is relatively large. Now the price is basically above 970:

MSI gtx970 gaming 4G ￥ 2349

performance reference:

8. 7990. When 7990 is not mining, 1200690 only needs 850 900 1000< In the past, the 7970 could only fight 760, but later they did 770. 680 is a little weaker than 770.

9. The first problem is that bitcoin mining is not a fixed operation. How long will it take to proce one. It depends on the floating-point operation of the graphics card to calculate the right number and get a bitcoin< The floating-point operation capacity of 7990 is 1.48 tflops.
the number of transistors is 8.6 billion
the number of stream processors is 4096
the number of texture units is 256
these parameters have a direct impact on mining
you can consider installing two or more graphics cards. To increase the computing speed.

10. The performance of the 7990 is higher than that of the 980, but it's easy to exceed the 980. The power consumption of the 7990 is very high. Generally, it takes more than 700W power supply to ensure the security. Moreover, the 7970 doesn't support al core. At present, either the 7990 or the 970980 has a high price. The 7990 is old. In terms of performance, the 7990 is good. Overall, the 970 is good, Now the cheapest one is around 2300, which is 20-25% lower than 7990 by default. TDP is only 145W, so overclocking is very easy
