The most amazing GPU graphics cards ever existed
GIGABYTE GV-3D1 (2005)
It was the first graphics card to join the two GeForce 6600 GT and it had a clear and distinguishing feature if we intend to use these GPUs: it had to be mounted on the GV-K8NXP-SLI board.
ASUS EN7800GT Dual (2005)
That same year ASUS took two G70 chips and did the same by joining them on a single PCB, giving life to the EN7800GT Dual for a price of 1000 euros, which meant the card was more expensive than this one. two GTX 7800 GT separately. Only 2000 units were made for this model and reached 489/679 MHz speed respectively.
Like the GIGABYTE version, it needed a 6 connector for its extra power. Although by then there were six online connectors, ASUS offered in a way that wanted to be able to offer more on the card.
By using its bracket, you can connect external power generators, such as a laptop, connected to an expandable cable and a final 6-speed connector, which was not repeated in the industry, but it was entirely novel.
ATI Radeon HD 3870 X2 (2008)
The HD 2000 ATI series did not bring much excitement, as the manufacturer soon had to launch the new competing HD 3000 on the best of NVIDIA and its G80, since the GTX 8800 Ultra was destroying the HD series.
After launching these and competing with Huang's, ATI introduced the HD 3870 X2 based on two RV670 chips that are connected to a single PCB using CrossFire technology and operating at 825 MHz, due to the faster than the HD 3870 separately.
They had a GDDR4 memory, a 256-bit bandwidth, and thanks to this AMD card, they came back with a performance crown, because NVIDIA didn't officially launch a dual GPU card at the time. The curiosity of this card is your need 8 connector connector installation by AMD's heatsink turbine, which meant that both chips had the highest temperature.
NVIDIA GeForce 9800 GX2 (2008)
NVIDIA didn't want to see how ATi was left with a working crown and at the time of filming they created a competing GPU to show its competitor and mentally sink its rival. The 9800 GX2 had it two GPs of G92-450 at 600 MHz and he had the moral to do two PCBs connected to one heatsink, so it looked like one PCB from the outside.
Huang's bet took an average of 25% more performance over the two AMD bets, so in addition to the technical display, it found greater performance and difference compared to the GPUs alone.
Gainward Rampage 700 GS GLH (2008)
It was the first card with factory compensation capable of exceeding the reference model and had a very specific serial accuracy. At the time Gainward was a TOP manufacturer and much of it was thanks to discacity for these types of models.
The Rampage 700 GS GLH came with the product heatsink at the time and had a dual HD 4870 GPU to its credit and serial overuls. Plus, he needed it 8 connectors and 6 connectors, which was a lot of heat on the card, so the brand sort of had a very cool watt heatsink, which was one of the first three cards to take up three spaces.
NVIDIA GeForce GTX 295 (2009)
Once again following the graphics card model with two GPUs, NVIDIA introduced its GTX 295 using two GT200b and had the differences of having two PCBs, one above the other in the middle was a heatsink like a sandwitch,
In order for the turbine fan to breathe, the PCBs were open at the end, so the card was able to hold the air up and down at the same time and in addition, the cover was made entirely to maximize heat transfer through the air, since the card consumes whopping 289 watts.
Higher consumption is considered 55 nm of your chips
Obviously, there are many dual GPU models in history, but those have either been very curious or unusual, so it's always good to remember that they understood how the market came about and what engineers thought in those years.
