Subj : Nvidia RTX 5080 leak gets some PC gamers worried that Team Green To : All From : TechnologyDaily Date : Wed Mar 13 2024 11:15:05 Nvidia RTX 5080 leak gets some PC gamers worried that Team Green hasnt learned from RTX 4080 fiasco Date: Wed, 13 Mar 2024 11:02:18 +0000 Description: RTX 5080 rumor suggests GPU could be some way off the pace of the RTX 5090 but lets not get carried away here. FULL STORY ====================================================================== A fresh piece of speculation on Nvidias next-gen Blackwell GPUs has got some folks concerned about how the RTX 5080 might turn out bringing back bad memories of the fumbled RTX 4080 launch (with that disappointing spec , and the whole faux pas with the canceled 12GB version ). Kopite7kimi, a regular leaker on the topic of graphics cards on X (formerly Twitter), stoked this chatter with the revelation that Blackwells GB203 chip (in the RTX 5080) will be paired with a 256-bit memory bus, and further down the range, GB205 will run with a 192-bit bus. Thanks as always. GB203 is 256-bit and GB205 is 192-bit. March 12, 2024 See more As ever, approach this assertion with caution its just a rumor. VideoCardz , which flagged this up, asked for confirmation that thered be no 384-bit GPU in [the] Blackwell family to which the leaker replied that it should be like this now. So, thats not a definitive statement of course, though no leak ever is and even if its Nvidias plan at this point, that could change. (Remember, the RTX 5090 is the only Blackwell GPU supposedly due to launch this year, late on, and the RTX 5080 wont turn up until 2025 so it's still some way out if the rumor mill is right). Analysis: What does this mean for the RTX 5080 then? Much of the focus with Blackwell rumors thus far has been on the idea that the flagship RTX 5090 will have a 512-bit memory bus (much beefier, 33% wider in fact, than the RTX 4090 ). This is the graphics card based on the GB202 chip. GB203 will be the chip down from that, the engine of the RTX 5080 as mentioned, with the assumption having been made that this would be a 384-bit bus, and that itd be upgraded from the RTX 4080 which has a 256-bit bus. (After all, the RTX 5090 is making a big leap from 384-bit to 512-bit, in theory, and all performance rumors point to it being a good candidate for our roundup of the best graphics cards ). Apparently, that isnt the case, and with a halved memory bus compared to the flagship Blackwell graphics card, this has some PC gamers worried that maybe the RTX 5080 will be a sizeable step down on the performance front from the 5090. However, we need to be careful here. Firstly, this could be inaccurate or Nvidia could change its mind, as already noted. Secondly, if the decision has been made to maintain a 256-bit bus with the xx80 model, Nvidia may have other improvements on the memory side of the equation that this fits in with. (This revelation has also been taken as a hint that Nvidia is running with 16GB of VRAM with the RTX 5080). Whatever the case, the spec that Nvidia shoots for will have to equal, or slightly better, the RTX 4090, for it to make sense and we can still fully expect that to happen. Or, the pricing might be adjusted, which could turn out even better for the consumer though to be fair, we find it hard to envisage a more affordable xx80-class GPU. In short, wed advise you not to worry about whats flying around the rumor mill at the moment. Nvidia will make the relative value proposition performance per buck for the RTX 5080 make sense compared to its predecessor, simply because it has to do so. Its exactly the RTX 4080 launch being so badly judged which should we hope make sure that Nvidia ensures that the RTX 5080 wont be viewed in the same light. However, that doesnt preclude the possibility that the Blackwell successor to the RTX 4080 could be very slightly worse off relatively, of course. All of this remains speculation, and well need to wait until later in the rumor cycle to see if these theories around the lesser spec memory bus persist.
