Amd RX 6000 Series graphics card is released from the flagship end, which declares that AMD will return to the competitive pattern of graphics card market after many years.
Undoubtedly, AMD's new generation of rdna2 architecture has made great progress.If we want to see more intuitively how much progress amd has made in this generation of products, RX 6700 XT is obviously a good observation object because its core specifications are very close to the previous generation RX 5700 XT.
Today, we will bring the AMD RX 6700 XT in-depth test report.
First of all, let's take a look at the overall product specifications. RX 6700 XT uses 40 groups of computing units, a total of 2560 stream processors. This specification is basically consistent with RX 5700 XT, and the core frequency is greatly increased to 2424 MHz.
The cache part RX 6700 XT also uses AMD's unlimited cache technology, with a cache capacity of 96MB. Gddr6 memory with 12gb capacity is adopted, and the bit width of the memory is 192 bits.
The TDP of the video card is set at 230W, which is the middle level at present. In addition, the RX 6700 XT will also support game technologies such as video memory smart, fidelity FX, etc.
Here, we compare the differences between RX 6700 XT and Rx 5700 XT. We can see that except for the reduction of the bit width of the video memory, other specifications are improved. According to the paper specifications, the conclusion is as follows:
In terms of memory efficiency, the bandwidth per bit width is increased by 14.3% (the measured frequency is increased by 14.1%). The core frequency is increased by 38% (the measured frequency is increased by 24.9%). The single precision performance is improved by 35.5%, and the pixel fill rate is improved by 35.5% (the measured performance is improved by 29.8%).
At the same time, RX 6700 XT provides 40 groups of optical tracking computing units and 96MB unlimited cache that RX 5700 XT does not have. This is a big part of the incremental consumption of transistors.
Product appearance introduction:
The product tested today is based on AMD's RX 6700 XT.
The overall appearance style of the graphics card is the continuation of the overall style of the 6000 series, and a belief lamp of the radon logo is provided at the top.
The back adopts a fully covered metal back plate to wrap the whole card.
The number of fans is reduced from three to two, which also shows that the overall power consumption of Rx 6700 XT is much lower.
Due to the lighter overall weight, the fixing screw holes of the bracket can not be seen at the front.
The overall length of the graphics card is about 27 cm.
The height is about 13 cm, slightly higher than the standard height.
The thickness of the graphics card is 4cm, which is a standard dual slot card.
The PCB length of the video card is about 2 cm, which is slightly less than the length of the whole video card.
