Kuai Technology reported on June 12 that the next generation of graphics cards from the three major companies will most likely have to wait until the end of the year. Among them, the most popular one is of course the Blackwell RTX 50 series. Now the configuration of the five major GPU cores of the new generation has appeared online, including The number of sm units, memory bit width and granularity.
top large core number gb202 will be equipped with 12 groups of gpc, each group of gpc is divided into 8 groups of tpc, and each group of tpc is divided into 2 groups of sm, so a total of 192 groups of sm, which is a sufficient increase compared to this generation of ad102 That’s 33%!
At the same time, the video memory bit width was upgraded from 384-bit to 512-bit, and the video memory particles were also upgraded from gddr6x to gddr7.
It's just that in the product, the sm unit and video memory bit width will not be fully opened. The latter is only 448-bit, and the full-blooded version is generally reserved for professional workstation graphics cards.
The flagship core gb203 will have 7x6×2=84 groups of sm units , which is only an increase of 5% compared to ad103, while the memory bit width remains at 256-bit, upgraded to gddr7, and the model is expected to correspond to the rtx 5080 series.
high-end core gb205 is equipped with 5×5×2=50 sets of sm units. Compared with ad104, it has reduced by 17%. The video memory is 192-bit gddr7. The model is expected to correspond to the rtx 5070 series.
mainstream core gb206 has only 3×6×2=36 groups of sm unit , which is exactly the same as ad106. The video memory has become 128-bit gddr7, and the model is expected to correspond to the rtx 5060 ti series.
entry-level core gb207 only has 2×5×2=20 sets of sm units. Compared with ad107, it is 17% less . The video memory remains unchanged and is still 128-bit gddr6. is also the only one that does not use gddr7. The model is expected to correspond to the rtx 5060 series.
Of course, it will still be half a year before it is released on the market, so there are variables that cannot be ruled out.
