Hd4870x2 bitcoin computing power

1. Amd officially supports it, but in fact it doesn't. Even if you hit the ATI stream SDK, it's just as ineffective. After all, opencl1.0 was not officially finalized until the end of 2008, and rv770 was already under development in 2006. As a result, there was more than two years of stalling. Question: is there a √ in the OpenCL column of gpu-z? Now I want to use this card to mine, but OpenCL is required to answer: gpu-z can't completely believe it. This software detects the hardware ID in the BIOS of the graphics card, and then compares it with the database to reflect some parameters. If HD4850 is installed, then add the ATI stream SDK development kit and corresponding catalyst. So OpenCL is checked, but it just can't mine. So that's why amd officially supports it, but it doesn't. After all, I haven't seen HD4 Series graphics cards.

2. The performance of 4870x2 is equivalent to that of gtx470, but worse than that of gtx560ti. After all, it's an old graphics card. What about al core. 8 can achieve this performance is quite 8 wrong, but the al core power consumption is too high.

4. 5870 is much more expensive. Of course, one is ddr5 and the other is DDR3. It depends on the bit core frequency of the graphics card. Don't be confused by 4870 5870 or its huge video memory. It depends on its rendering pipeline. Zhongguancun can easily find out the specific parameters and prices of these two graphics cards. I think 4870 is enough to play all the mainstream high-end games

6. There are two important indicators of the graphics card, one is the pixel texture filling rate, which refers to how fast the graphics card provides. The second is bandwidth, which refers to the speed of data transmission provided by the graphics card

hd4870x2: pixel texture filling rate: 12g, 30g / s. Bandwidth: 115g / s.

HD5970: pixel texture filling rate: 27g, 68g / s. Bandwidth: 154g / s.

both graphics cards are power intensive. The measured power consumption of the former is about 252 to 286w. The latter is about 270 to 291w

for such a graphics card, the power supply above 600W rating is the basis. Must be on the game type large chassis, group chassis fan to form air ct. Noise and heat dissipation are big problems

hope to help you.

7. On the whole, both are strong
just playing games, gtx295
is better than 4870x2
n card has a congenital advantage in games
a card has advantages in graphics!

8. 6850, after all, is a new proct, and its energy consumption is much better. If you use 4870x2 to replace it, it's also a cost to replace the power supply. The CPU is OK, and it's OK to exceed the point. I said upstairs, 3.5

9. The performance of HD4870 * 2 is far better than 9800gt

the performance of HD4870 * 2 will not be better than gtx295. In short, HD4870 * 2 is two HD4870, gtx295 is two gtx275 (absolutely not 260 +), and gtx275 is one grade higher than HD4870

10. In fact, I can't understand it that way, because the same graphics card with different CPUs can achieve different performance, But there is always a relatively stable parameter, such as 8800gs. You can hardly feel the difference between E5200 and e8400 when you play games with E5200. The most important thing is that the score of e8400 with 8800gs will be higher when you test it.
back to the topic, the parameter of 4870x2 is really frightening. It's amazing to have only 1600 stream processors, but as long as the CPU reaches above e8400, there won't be any obvious bottleneck
now let's talk about i7 processor. If you have paid attention to its features, I won't say much about it. The new architecture has higher execution efficiency, low latency L1 L2 cache, 8m L3 cache, and native 4-core 2.93g high main frequency band, more than 4870x2! It doesn't need 8-core CPU at all. Ha ha
when 8-core CPU comes on the market, it's estimated that the graphics card has developed to 5870x2 or 6870x2. Ha ha ha, this is a joke
