  • I got 31.5K with my 7900XT Taichi :) Fully stable too.

    BUT I’ve started to notice the hotspot creeping from 75c with this overclock profike, to 100c slowly over the past few months. Has to be pump-out… It’s even getting colder (ambient).

    Where can I get some PTM 7950 in Europe? I found a tub once but it was like €500 lol.

    I also have a tube of Gelid paste that’s supposed to be really good against pump-out because it can handle slightly higher temps (around 80c is where most pastes start to detoriate) but if PTM is affordable, might as well go that way. Memory is fine but a 60c core and 100c hotspot is not.



  • It would also increase cost, and Navi43/44 don’t need that extra performance. They will probably be slower or at best the same speed as a 7800XT. On the flipside they’ll be dirt cheap too, probably with a good chunk of VRAM, so really good low-midrange cards that actually work in games unlike Intel.

    Unless AMD is already going for multi-graphics chiplets and they just slap on four Navi43 chiplets to create a flagship. That would be pretty epic and is an option still on the table, they already have a proper functional chiplet design fir their AI cards. But I think we won’t see that until RDNA5.


  • Maybe, but it would be unnecessary because RDNA4 caps out at midrange so GDDR6 would suffice. AMD decided to cut RDNA4 high-end to produce more AI chips and earn more money, and give their engineers more time to get multiple GPU chiplets on 1 card working for RDNA5, which is where the real performance boom is at. RDNA3 still has 1 graphics die, only the memory controller and cache is on separate chiplets.

    So the 7900XTX will remain AMD’s flagship until RDNA5.

    There might be some kind of refresh of the 7900XT(X) with slightly better performance and efficiency, maybe those would use GDDR7 if possible and economical.

    The good news for current owners is the 7900 cards have plenty of VRAM to last until RDNA5. The bad news is there will be no competition fir the 5080 and 5090 so expect even higher MSRPs than the 4000 series. $2500 MSRP for a 32GB 5090 wouldn’t surprise me. And $1500 for the 5080, the “gaming flagship”.

    If you were waiting for next gen hoping value would improve vs the 4000 series… I hope you have even more patience.

    The moment I heard the news about RDNA4 high-end being scrapped and the monster chiplet design was moved to RDNA5, as well as the high AI demand and lack of production capacity I pulled the trigger on a 7900XT because next gen is going to be absolutely bonkers on the Nvidia side and nothing better will be released on the AMD side other than software improvements, maybe a refresh of the 7900 cards but that’s it. This card with 20GB VRAM will last me until RDNA5/RTX6000.

    Jayz2cents also made a video a while ago voicing his opinion to buy a GPU now cause it’s only gonna get worse in the coming years. A situation arguably worse than the crypto boom, combined with a lack of competition for 80 and 90 series and Nvidia’s Apple approach… Bad news.

    Intel won’t have a truly viable product for general gaming within this timeframe either. Even today their drivers are lightyears behind both AMD and Nvidia with performance all over the place depending on each individual game. And Intel too is making AI chips based on GPUs. The consumer GPUs are like a proof of concept.


  • 32GB 5090 and 24GB 5080 is the most realistic configuration.

    Also expect both of them to have ridiculous prices. $1500+ for the 5080 and $2500 FE MSRP for the 5090 wouldn’t surprise me. AMD is skipping high-end for 1 generation so their competition will likely be a $1000 5070Ti. The 7900XTX or a refresh of it will be AMD’s flahship until RDNA5. They have their valid reasons for that but it’s very bad news for Nvidia customers, as much as they like to bash AMD.

    Nvidia also wants to protect their way more expensive professional lineup so especially the 32GB 5090 will be priced to the moon.


  • It’s practically guaranteed, there is no other realistic configuration.

    I also expect the 32GB 5090 to launch at $2000-2500 MSRP and the 24GB 5080 at $1500+ because AMD is skipping a generation and the 5070Ti will likely match AMD’s offering at $999. The 7900XTX or a refresh of it will remain their top card until RDNA5.

    Next gen Nvidia prices are going to be absolutely bonkers, worse than now. And people will buy them anyway… Especially because many have skipped the 4000 series hoping things would improve. With RDNA5 and more production capacity from new fabs prices will likely improve but that’s at least 3 years in the future.


  • More memory bandwidth does not translate 1:1 to more performance. The GPU core is by far the most important. Even at 4K the current 1TB/s memory bandwidth is sufficient and overclocking the core is what gets you the most performance.

    We’ve also seen that the 128-bit 4060Ti 16GB with its pitiful bandwidth can utilize its full 16GB VRAM without any issues at 1440P.

    So if you’re trying to estimate performance gains, the core is where you should look for now, especially if Blackwell keeps the increased L2 cache (Ampere’s cache was measured in kilobytes, it was a radical change and it definitely worked well for AMD with RDNA2 too). Unless you’re doing 8K gaming the extra memory bandwidth will have minimal impact.


  • It’s because AD102 is already a huge monolithic die, a little over 600mm2, with 814mm2 being the theoretical limit. In short: the bigger the die size the lower the yields, there will never be a gaming GPU much bigger than 600mm2 because then you’re looking at terrifying prices.

    A node shrink only helps so much, and you don’t want a GPU sucking 800 watts either. The wider memory bus also takes up extra space. The 5090 is still monolithic so a ~30% improvement in performance sounds plausible.

    Even worse, AMD (underatandibly) is “skipping” RDNA4 high-end to both maximize AI production and give their engineers more time to get a chiplet design with multiple graphics chiplets working well.

    RDNA5 will likely be high end again, but until then, the 7900XTX or a refresh of it will likely remain the fastest AMD card.

    Which means next gen Nvidia pricing will go through the roof. We’re probably looking at a $999 16-20GB 5070(Ti) that matches AMD flagship performance so I wouldn’t be surprised if a 24GB 5080 will be priced at $1500-1750 MSRP as the gaming flagship and the hybrid 32GB 5090 $2500-3000 MSRP. Remember the 3090Ti launched at $2000 despite gaming competition from the $1000 6950XT.

    … And people will buy them. RIP GPU prices for the next 3 years, at least.
