NVIDIA RTX 2080 graphics card internal first exposure: core code TU104

via:快科技     time:2018/8/18 0:01:40     readed:293

It can be seen that the new card core code is "TU104",among themThe first letter T corresponds to RTX(formerly G and GTX),The second letter U corresponds to TuringThat is, the Turing architecture, the last three digits are the core level number.

RTX 2070 will also be this core, and there should be upTU102(TRX 2080 Ti), there should be downTU106(RTX 2060), TU108 (RTX 2050).

TU104-400-A1The full numbering also conforms to past practice and represents the first revision, along with "Qual Sample"The words, representing quality verification samples, are very close to the retail version.

Although there is no specific size data, it is obvious thatThe TU104 core is much larger than the GP104 currently used on GTX 1080. It is said that there are 3072 streams.processor, an increase of 20%.

There are also eight memory on the card, all on the front, corresponding to 8/16GB GDDR6, and the memory bandwidth should be 256-bit.

Power supply can be seen8+2 phase power supply circuit, and an 8-pin and a 6-pin auxiliary power supply interfaceThe maximum power supply capacity is 300W, which means that the power consumption of the new card will increase, and the GTX 1080 is now only 180W.

In addition,At the top of the graphics card, there is a new SL gold finger, plus a wireframe diagram for simultaneous exposure. Obviously, this time there will be a new multi-GPU SLI technology that may be used with the NVLink interconnect bus.

And the output interface has a significantly small, perhaps USB Type-C, to support VirtualLink.

Someone released the internal part of the radiator and can seeLarge area of ​​copper, especially part of the GPU core areaFrom another side, it proves that the power consumption of the new card cannot be underestimated.
