![]() You shouldn’t expect something like that. Overall really like this card, mine had a little bit of capacitor whine sometimes though. I might even stretch for the water cooled one. Which driver version did you use? Which OS? Which 390X do you have, what are the clocks?Īlso, I plan to return this 390x despite my positive experience with it to best buy in a few days because the air cooled Fury card come out next week and should be better, that HBM is around 4 times faster or something crazy like that. Cycles seems unable to utilise the full computing power More details would be nice. I’d even say this is not gonna happen using cycles as the card is nowhere near its power or temperature limits. It’s wrong to say the 300 series reduced the power consumtipn, e.g. Some of the 300 series cards got new PCBs and coolers from the board manufacturers. The most obvious change is the new driver (not omega iteration 2, this one is upcoming), which is not yet released for the 200 series. The Hawaii Chip on 290X and 390X is exactly the same. Monitor it with GPUZ if you want, it may explain why the overclocking doesn’t bring anything. 290x cards are fast but tend to overheat and throttle (reduce their frequency) in summer. They have a new voltage controller that really reduce power consumption, thus temperature. For your 290x, the 390x are not only rebranded cards. I’m very curious how this is going, also when I switch to Windows 10.įrom my test, the new win7/8 drivers after Omega didn’t change performance, only the windows10 one brings huge speedup. I think the main reason would be the driver, as I use the fairly old 14.12 (original omega release) on Windows 7. Even overclocking to 1100/1400 MHz (Core/Memory) didn’t bring more speed. My Card don’t even fill 2/4 GiB for this scene. However, I don’t think it has anything to do with 8 GiB memory in this case. I ran the BMW27 benchmark with my R9 290X with default clocks and don’t get below 1:20. Which driver version did you use? Which OS? Which 390X do you have, what are the clocks? I didn’t have any issues once I set things up right, but others apparently did. Let me specify which single device the realtime render uses.ĭevelop more to reduce crashes and bugs. This effectively removes or reduces the bottlenecking problem. This really would have sped up my overall render time. If I had this option, I would have made the 390x do around 512, the 650 do around 128, and the CPU around 16. You must be able to specify which device the realtime render uses, because when I was using all the devices it did not seem to work/it was really slow.Īdd custom tile size options for each device. Realtime preview rendering does not work well… if at all. I thought it would be better to exclude the CPU as it is the slowest tile and needs to be the smallest too, but you can not configure it like this. I could not tell Blender to use just the CPU+one of GPUs. I could not tell Blender to just use the R9 390x + 650 This meant that while my 390x would get done with all the tiles it could rather quickly, the last two tiles belonging to the i7 and 650 would make the render take quite a bit longer than if I just used the 390x alone. The tile size for the CPU must be under 128 otherwise it’s just stupid slow, and the GTX 650 would not do well above a tile size of about 128. My R9-390x is able to do the BMW2 Benchmark in 54 seconds flat with a tile size that covers the entire thing, this is because it has 8GB of GDDR5 on it.ġ.When rendering with other devices as well as the 390x, the tile size has to be smaller which in turn bottlenecks my 390x. Sounds like a dream but there are a few problems, regardless there is massive potential I think, let me explain… We will be comparing the Sapphire Nitrio 390 and eVGA GTX 970 SC.Yes, I got it to work on all three and the render even came out flawlessly with no broken tiles. Each of the benchmarks will be run with pre-configured settings at 25601440 resolution. All benchmarks are run five times with the results averaged. All testing was done with a fresh install of Windows 8.1 Pro 圆4 with all patches and no additional software running. Before jumping into doing some benchmarks, lets take a look at the test system.
