At present, Nvidia has released the Blackwell architecture GPU, and said that in the second half of this year, you can see the RTX 50 series graphics cards based on the Blackwell architecture, among which the parameter information of the flagship card king RTX 5090 has been exposed relatively completely, and there is no accurate news about other RTX 50 series graphics card families so far. Now there is a revelation that the god has revealed the specifications of five different cores of the RTX 50 series graphics card, including SM unit, video memory type and particles, among which the GB202 card king parameters have nothing to say, but the mid-to-high-end GPU parameters have been slashed, which is unexpected.

From the naming point of view, Blackwell will have five different cores, including GB202, GB203, GB205, GB206 and GB207, of which GB202 is the flagship model, and the specifications are also the most powerful, with 12 GPC, a total of 192 SM units, equivalent to 24756 stream processors, which is 33% higher than the current RTX 4090 stream processor specifications, and the video memory has also changed from GDDR6X to GDDR7, The video memory bit width reaches a terrifying 512bit, of course, the RTX 5090 should be slightly castrated on the basis of GB202, for example, the video memory core is 448bit.

RTX 5080 used in GB203 is only a small upgrade, SM unit increased by 5%, using GDDR7 video memory, the rest has not changed, as for the GB205 core for the high-end market, it is really confusing, compared with AD104, it has reduced the core size by 17%, perhaps Nvidia feels that just the increase in frequency and the improvement of the architecture have been able to make the GB205 core have a pretty good graphics score. You must know that GB205 corresponds to a graphics card like RTX 5070, which is considered a mainstream graphics card in the hands of gamers.

GB206 is the same as AD106 in the number of stream processors, GB207 The number of stream processors has been cut by 17%, which should be used for RTX 5060 in the future, and this graphics card does not use GDDR7 video memory but continues to use GDDR6 video memory, which is not very optimistic about the performance improvement, it can only be said that mainstream players are still embarrassed when choosing a graphics card, and enthusiast players have no brains to choose RTX 5090 graphics cards. As for whether Nvidia will launch a special graphics card for the domestic market, it is still difficult to say.
