    Do tell.

    Complete rubbish. China has been investing in its own fabs for decades. That's how long it takes to develop such expertise. I'm sure that once Huawei got banned from TSMC, it created a new urgency and upped their investment, but probably only accelerated their development by a rather small amount.

    Again, that was already happening. Anything the US did merely accelerated it by a couple years.

    People like to have simplistic explanations for things. Usually, there's not a single, simple explanation for such complex things. Just because you can see what appears to be a financial interest doesn't mean it factored heavily (or even at all) into the decision.

    Yes, that´s the cost of protectionism. In the short run you support your own industry, in the long run you loose out as your comptetitor now has a motivation to build their own. Once the competitors compete with your local companies, some might start to implement hight import tarrifs, which might lead to stalled development inside the own country, as their is no longer any competition from outside.

    I guess in the GPU/Accelerator front china is way behind, but in the chip manufacturing + SoC Development, they will compete in ~5 years.. They are currently developing their own EUV process + they are pushing a lot of money into that. There are also some RISC-V SoCs like the TH1520 (Quadcore 2,5 Ghz C910 RISC-V Design) and enablement work in Android AOSP recently (initial patches developed by Alibaba got merged upstream last month).
    I guess we will see the first entry level mass market phones / notebooks / desktop PCs based on the TH1520 in mid->end 2023.
    They have most of the tech needed now in-country, Alibaba makes SoCs based on RISC-V Huawei/HiSilicon makes RF-Chip Designs for 802.11ax and 5G Networks, SMIC can produce the chips. They have a 7nm process which is comparable to the first TSMC 7nm now in mass production.

    They are only lacking a good GPU Design for embeeded devices and a lot of software.

    I hope its closer to 90%. At least in rasterization work. We won't know until release.

    Keep in mind NVIDIA can't even get decent framerates (60-120) at 4k with RT enabled without the help of DLSS2+3 so RT while being cool, isn't really a dominate factor in buying a card just yet. Most people keep such a thing disabled, and very few games have acceptable implementations that offer good fps and decent visual upgrades. (I can't even remember which ones off top of my head)

    The main special feature of the Radeon 7000 series, at least for those who do not care about games (because the game performance remains to be seen in future reviews), is a much better performance per dollar than for the NVIDIA GPUs. The DisplayPort 2.1 is just a bonus.


    If AMD had not offered a better performance per dollar, then there would not have been any reason to buy an AMD GPU, because the NVIDIA GPUs have much better software support, also on Linux, where the NVIDIA drivers, settings, CUDA libraries and SDK etc., work very well.

    Both AMD and NVIDIA have chosen prices for their second best card so that their top card has much better performance per dollar, even if at a higher price. In this way they can milk both the buyers who can afford to buy whatever provides the best return for their money and those with a limited budget, which will be content with the slower but less expensive card.

    The price and performance (measured as FP32 throughput) for Radeon 7900XT have been chosen so that it matches RTX 4080 in performance, but it matches RTX 4090 in performance per dollar.

    For Radeon 7900XTX, the performance is 77% of that of RTX 4090, but the price is only 62%, so the performance per dollar is higher by 25% for AMD.


    So, for non-gaming applications, the buying decisions are already clear, one can choose NVIDIA GPUs to minimize the cost in time or in money for software development, or one can choose AMD GPUs to minimize the hardware cost for a desired performance target.


    The performance per watt seems to be similar for Radeon 7900XTX and RTX 4090. NVIDIA has just chosen to make a bigger and more power-hungry GPU, to obtain a proportionally greater performance. If however someone is not willing to provide an adequate case and power supply for the huge RTX 4090, RTX 4080 has a so bad performance per dollar in comparison with any AMD GPU that it cannot be considered as a wise purchasing choice.


    Price to performance per dollar would only apply to gaming regarding the 7000 series. In rendering/deep learning, the RX 6000 series was getting wrecked by Nvidia's mid-range GPUs which cost less than the RX 6900/6950. We still have no clue how well the 7000 series does in deep learning. At first I thought AMD's AI accelerators were their matrix cores from CDNA but reading other articles it seems like they're just inference designed cores to accelerator FSR3. I bought a Titan RTX back in 2018 due to the Titan drivers and unlocked tensor core performance while their Geforce cards are limited to 50% performance. $2500 seems like a lot for a GPU but it paid off since I've had that performance since 2018. This can also be the case for ray traced games as well. Pay a bit extra now but have a card that last longer.

    I can't say much about the latest round of trade restrictions. I think we can probably agree that if they're not part of a coherent strategy, they'll ultimately be short-lived in their impact and probably even self-defeating (i.e. by forcing China to become more self-sufficient in fab capability and supply chain).

    You can probably find many such points, in the past couple decades, when applying such sanctions might've seemed suspicious. There's a bigger picture and that's what matters. The thing I can't say with much certainty is exactly how it's being framed.

    AMD made some comment about their RDNA3 cards being more future proof. I disagree as we continue to see ray tracing adoption these cards will have longer longevity. Similar to how the GTX 400 series performance out lived the HD5000/6000 series due to the adoption of tessellation.

    You have to remember Nvidia’s consumer cards are GPGPUs while with RDNA, AMD switched to making gaming GPUs. It’s very rare to see an AMD RDNA card mentioned in publications. While you’ll see plenty of RTX cards used. Same with content creation thanks to Nvidia’s Studio Drivers. At the end of the day Nvidia’s GPUs are targeting multiple markets while AMD with their poor performance in the other markets with their consumer cards are restricted to just the gaming market.
    Indeed!
    Even for gaming AMD GPUs sucks as on Linux you cannot even play all games for sure as we cannot possibly have 100% or near-100% compatibility with all games as AMD still refuses to support a simple feature like SR-IOV.
    As for compute the support always sucked and sucked big time with that awful ROCm not coming by default installed on any distro as Mesa drivers come and if you tried to install it yourself, it was very hard with many errors and problems.
    So, the whole good for gaming marketing that AMD keeps pushing, looks to me like false advertising as there's no gaming at all when you can't even start the game when the game is not supported by WINE.

    Perhaps the bigger concern they have is to minimize impact pricing on previous-gen products they still have in inventory and in the sales channel. Once those inventories dwindle, they can always re-price their second-tier models lower.

    I think it's pretty rare for the top-tier card to offer the best perf/$, because most people willing to spend that much are out for the best performance at (almost) any cost.

    You're reading waaay too much into fp32 TFLOPS, here. They have traditionally correlated poorly with actual gaming performance.

    Don't forget to include an active fire-suppression system! Those 16-pin power connectors are a disaster!

    That would be rather short-sighted, don't you think? I really doubt that's goal.

    Listen people, just take the numbers: 12K Amd Shaders = 18K NV ones, that's because Amd is Triopperant 2FP+1INT and not 2FP_or_2INT. Then each Amd shader group can handle 50% more Special RT work by moving BVH to Asic, that is what NV does. They will have around the same frequency except from the Command Group where Amd people can OC it to around 3Ghz permanent regardless of the shader clock and savings. Will have equivalent software like Upsampling - Frame Generation - Low Latency - Video Processing. Amd Bandwith is unprecedented. Amd will have better Vector adn Scalar wile NV will still have better Matrix calculations.

    So about the same Gpu with only deferent size whatever this means for price and consumption, Amd is 58BT wile NV is 76BT and about 30% heavier. The equivalent size from Amd will be one with 16K shaders but that's a lot faster and still cheaper due to Multi Chip tech.
