I wonder if Zen 3 will finally let AMD pass Intel in single threaded performance. I thought they had already, but just a few days ago I checked benchmarks and saw that my 8086K still beats a 3800XT. Though maybe I'm stuck in the past a bit thinking that single threaded performance is even still important for games.

I'm looking at you, TF2 & PCSX2.

As a linux-only user (and gamer), nvidia is a plain no-go for me so i just hope that rdna2 is not entirely disappointing like RDNA1 was. For us Linux gamers a working VFIO on a consumer card would be a dream of course since nvidia is locking that to their workstations cards, maybe AMD just throws it in as a goody. Zen3 is propably gonna kick-butt, especially in any non-gaming task perhaps AMD will inch closer to Inte…

Wouldn't SR-IOV support (which is rumored in nvidia's chips) make vfio on this kind of setup possible?

VFIO is already possible with amd if you have supporting hardware i.e. i was running single vega guest windows guest and linux furyx host on tr4 board but with sr-iov you could run many guests using same gpu, i think stadia uses this now. There were also rumor that vega has sr iov but disabled on hardware

The last time I owned an AMD video card was more than a decade ago. At the time their video card drivers needed work and could blue screen your box. There was a lot of back and forth on the internet about which driver version to load to get the most stable experience. Fast forward to 2020 and the perception about AMD's video driver quality seems to be in a similar place: https://www.pcgamesn.com/amd/radeon-big-navi-d…

> Fast forward to 2020 and the perception about AMD's video driver quality seems to be in a similar place Maybe for Windows, but the same cannot be said of Linux or macOS, where AMD's choice to open-source their drivers has led to these OSes having great support; while Nvidia, having to support their own closed-source drivers, seemingly hasn't had the bandwidth to get their drivers for these OSes up to par.

And you can undervolt your AMD card with the open source drivers to improve efficiency and gain performance at the same time.

This. I've already decided my next GPU will be AMD regardless of if it's competitive at the top end in terms of performance. I am so sick of nVidia's Linux driver bullshit that I cannot wait to drop them. I don't game that much anymore anyway.

AMD is great for gaming on Linux, especially with projects like radv and ACO.

I'm not super interested in Linux gaming, I just want my desktop to be usable.

It only is if you're running low resolution and/or really high refresh rate. Otherwise a top tier GPU is still your limiter.

My firm does GPGPU programming for audio processing. Nobody in this area even thinks of using anything other than CUDA. It has far more support, tools, compilers, etc.

What about the Mac side of things ? Mac's are still pretty big in audio production, but they don't support CUDA (and don't come with Nvidia GPUs any more anyway). How does Metal Compute stack up ?

We don't use Macs. While many uusicians use macs, the people on the engineering/scientific side of things don't. We're not doing music audio.

Some of the leaked benchmarks for the 3080 put it more in the range of 30-50% better than the 2080 series: "30% Faster Than The RTX 2080 Ti & 50% Faster Than the RTX 2080 SUPER on Average" https://wccftech.com/nvidia-geforce-rtx-3080-graphics-card-b...

AND those early benchmarks were from Nvidia on very specific DLSS and RTX workloads that may not have been representative to many games people play.

Does it really matter for gaming?

> The information available around Big Navi (The GPUs expected to launch next month) put them at a +50% performance jump from the last generation and likely able to compete with the Nvidia flagship 3080 I guess it depends on what benchmark you care about but for AMD to compete with a 3080, which is 70-100% faster than a 2080, which is 10-20% faster than AMD's current flagship, they need to do a lot better than +50%.

Depends on price. Nvidia might have owned the tippity top with their 20xx series but the 5700xt was a very strong card for medium priced builds and as a pc building enthusiast would’ve been the card for my next build alongside an amdR5 3600 cpu. At launch it had driver issues but they were cleaned up and at $350 it was a total steal compared to a 2070 at $650 for similar performance.

I agree. They don't need to beat the 3080, they just need to match or beat the 3070 at a competitive price. I would say the majority of the market does not have $700 to blow on a GPU. Having compelling options under $500 would be enough of a win.

I highly suspect Apple will still ship (and support) AMD GPUs - maybe for the iMac Pro and Mac Pro. I doubt that Apple Silicon GPUs will be close to the performance to AMD/NVidias flagships. And I assume the market share for iMac/Mac Pro is just not that big for Apple to invest in competing with AMD/Nvidia on the Highend Segment.

OTOH Apple also needs dedicated GPUs for some of their MBPs and the bigger iMacs. I think they will end up ditching AMD to have 100% E2E control on all their products.

Apple's MBP drivers have been broken since 2016 and getting worse, high-frequency locked and thereby thermally throttling the CPU at idle. I don't know if that means Apple Silicon will be better or if they are just incompetent at it.
