is the last generation Kahuang of amdr9295x2, but now it's no longer good. Now amdr9295x2 is the most powerful
R9 295x2, which is composed of two complete specification Hawaii cores (R9 290x). The frequency of the core has not decreased, but has increased compared with R9 290x. Although the exchange of fire will consume part of the performance, the overall performance can't be underestimated. What's more, the unprecedented 500W power consumption of a single card has set a record of the highest power consumption of a single card so far. It is also the first time that a public version card has directly integrated a water-cooled radiator into a radiator, which can be described as a gimmick
compared with the appearance of previous amd flagship cards, R9 295x2 has changed a lot. No longer use the black and red matching scheme of plastic feeling, but change to the silver and black matching scheme full of metal feeling, the texture is more obvious. In the past, the high heat of hd7990 made amd designers rack their brains for radiators. Now R9 295x2 directly applies the solution of liquid cooling and air cooling of ASUS in the non-public version of single card and al core. The heat dissipation layout of R9 295x2 is very similar to Ares II, and the heat dissipation solution is also provided by asetek with high integration. The two water cooling heads are arranged in series, the heat dissipation effect of the two cores will have mutual influence factors, but the difference is not too big. Two 38 cm long fully enclosed rubber tubes are connected with the heat sink. The length and thickness of the heat sink are 152.5 x 38 mm. You can choose to install up to two 12cm fans (with one). According to the previous leaked information, asetek's solution is: the water pump is built into the water cooling head, and the pure copper bottom is in direct contact with the GPU, The inner part is in full contact with the water cooling liquid through the micro channel structure. Two water cooling heads should be equipped with a water pump, which can adapt to the high resistance of micro channel structure and obtain better heat dissipation effect. In addition to the use of water cooling to quickly take away the heat of the two GPUs, the PCB surface is covered with integrated metal fins, and the power supply part in the middle section is also equipped with pure copper fins. The heat generated by electronic components can be quickly taken away under the action of fans and fins. The layout of R9 295x2 components is very regular. Every inch of space on the PCB is fully utilized. Each core can be divided into six phases for power supply, which is the same as the public version R9 290x. The exchange of fire between the two cores is completed through the bridge chip proced by PLX. Surprisingly, for such a high power consumption al core graphics card, the auxiliary power supply interface is only 8 + 8pin. As a flagship card, of course, it has to have flagship output. The mini DP X4 + pure digital DVI X1 absolutely meets the multi screen needs of the target population. With AMD's eyefineness technology, it can easily achieve a variety of multi screen display combinations

The highest graphics card at this stage.... Single card invincible existence..... It can't be well described
2: adjust the display resolution to the lowest or the second lowest from the bottom

the 295x2 of the former uses water cooling for heat dissipation. The only disadvantage is that it has a cold exhaust, so there may be no place to install it in the chassis. But the cooling effect is very good
Dylan devil 290x is the same as 295x2, but it uses three fans for heat dissipation, so there is no place to install cold exhaust on the chassis, as long as it supports 30cm graphics card. It has four 8pin external power supply, which is twice the 295x2, which means that the overclocking capability is good. The maximum power consumption is 500W. In terms of performance, they are almost the same.
