Past generations of open-core graphics cards
Speaking of open core, I believe that many friends' first reaction soon is AMD's open core processor. Since the classic 45nm Athlon 5000 in 2009, open-core processors have been occupying the low-end player market, and you can enjoy the treatment of thousands of yuan for a few hundred yuan, which makes most players salivate. Compared with processors that need special means to achieve the effect of core opening, the history of core opening of graphics cards with BIOS is much longer. Let's go through the time machine, open the dusty history and count the classic graphics cards that can be opened. ATI radium dragon 9500 128MB

Back in 2002-2003, with the launch of R300 core, ATI swept Geforce Ti4600, the strongest NV in that year. The Radium Dragon 9700 Pro, which was the first to support Directx9 special effects, enabled ATI to defeat NVIDIA, the arch-enemy, indisputably, and reinvigorate its glory. However, no matter how high-end products are, they can only prove the technical strength of manufacturers, and they can't bring much benefit in market competition and consumers' minds. So ATi introduced the Radium Dragon 9500 for the mid-range market. The radium dragon 9500 has four pipelines, and all eight pipelines can only be enabled by changing the resistance state of the core end. After the BIOS is refreshed, it can be transformed into 9700 with 256-bit memory specification of eight pipelines, which is improved by nearly 100% in actual games, and once became an "artifact" in the minds of gamers.

Compared with the transformation of Radiron 9500, it needs hard-core resistor modification and BIOS update. Some manufacturers use the same PCB as 9800Pro, and the hardware specifications are the same as 9800PRO, using 128M/256Bit. Only by cracking the corresponding driver files can the four blocked pipes be unlocked, reaching the level of 9800PRO, which is very powerful. ATi Radium Dragon X800 Professional Edition

As we all know, X800XT and X800Pro are both produced on the same production line. Compared with the extremely expensive X800 XT, the Laser Dragon X800Pro graphics card is closer to the affordable level of consumers. Compared with the classic radium dragon 9500 and radium dragon 9800SE, the transformation process is similar to that of radium dragon 9500, and it also needs to modify Jinqiao and BIOS, which is more complicated. However, it has become a top graphics card, so why not? AMD radium HD 4830

After several years of silence, open source graphics cards reappeared. The core of HD 4830 is RV770, but the complete SP of 800 shields two of them *** 180 SP, which reduces the frequency. However, players found that some HD4830 actually had a complete 800 SP. After overclocking to 625/2000 Mhz, the performance is basically the same as that of HD 4850, making HD4830 800SP a hot classic product. AMD radium HD 6950

With the release of HD6900, in addition to the brand-new 4D architecture, the biggest feature is that the public version 6950 is close to 100% and transformed into 6970. 6950/6970 have the same core architecture and the same number of transistors. Even the power supply in public PCB is similar, and the biggest difference is the difference in power supply. When the graphics card was launched, players found that almost 100% of the public version of 6950 could be "upgraded" to 6970 by refreshing the BIOS. Even if the crack fails, the risk of refreshing BIOS of the Radium HD 6900 series graphics card is greatly reduced, because it is directly equipped with dual BIOS and switch, and there is a backup in case of failure. AMD radium HD 6850

Different from the previous nuclear opening, recently, a manufacturer of AIB (the highest level partner of ATI graphics card official certification) launched the HD6850 graphics card which can guarantee 100% nuclear opening, and adopted a non-public design. At the same time, compared with the single 6PIN auxiliary power supply used in the ordinary 6850, the built-in dual 6PIN power supply has a 4+ 1 phase design, even more than the public version 6870. Dual BIOS also ensures the stability of kernel opening. With 6870 BIOS, core opening can be completed by jumper. Compared with the previous open-core graphics card, it needs hardware-level transformation and faces the risk of refreshing BIOS. The new graphics card has become a quite distinctive function. .
