The Vega conversation become too heated for me. I know that people are very excited about this card. I assumed there would be lots of reviews of Vega FE at launch, but everybody started to ask me to do a review instead. I even got requests from press to come and benchmark to our office. There's no conspiracy or anything. I am just letting AMD and the press to do their work, while focusing on my own.
I am currently finalizing our tech and I have my hands full of tasks. I skipped E3 and SIGGRAPH this year to have more time to get things done. Our launch is getting closer and shipping to 5 platforms (base & upgraded consoles + PC) with a 3 people team is pretty hard.
Vega is working well and I use it daily. Async compute is also working fine. I had plans to test some fp16 code on it, but I found out that Unreal Engine doesn't yet support fp16 on PC. So I am waiting for Epic to add fp16 support before I continue with fp16 work on PC. Ran my buffer benchmark on Vega (
https://github.com/sebbbi/perftest), and noticed no surprises. It behaves like any other GCN based GPU (same peak perf/clock on various L1$ buffer load operations). Our game is mostly ray-traced, so it has no very little overdraw. Tiled rasterizers shouldn't help much at all, so I haven't spend any time confirming gains on that regard. I will test DX 12.1 features (especially volume tiled resources) after our game launches.
The card is very quiet. Even when playing our game at 4K without vsync. Running it at stock settings (like our CPUs and other components). In gamedev hardware stability is always more important than slight perf increase. I'd assume AMD has plenty of headroom to run the fan faster in consumer release if they want to.
