Strange to have less than 1070ti performance with This 5700XT in luxcore.

Indeed!

Geekbench 4.0
GeForce GTX 1070 Ti
170559
AMD Radeon RX 5700 XT
332502, AMD Ryzen 5 2600X, 3.6/4.25 GHz, 6 Cores, 12 Threads, DDR4 SDRAM 1600MHz
204378, AMD Ryzen 9 3900X, 3.8/4.23 GHz, 12 Cores, 24 Threads, DDR4 SDRAM 1588MHz

I cannot see any reason why one system is 1.5 times faster. Most systems have approx. the speed of the slower system. This means the card is currently 10 to 20% faster than 1070 Ti.

According to some prof. HW tester current AMD openCL driver for 5700 XT is weak what may explain the bad LuxCoreRender values.

I really hope there will be better drivers soon so that you can get the best out of your hardware!
Can you share some Luxmark results?
Edit: Oops, I see they are already in the table

Actually shared already in the picture of the table attached to a former post.

But well...

Any possibility to ask AMD if RDNA 5700(XT) performance under Luxmark are correct or Driver Limited ?

I thought to ask them some day. I may ask AMD soon because it looks like real issue. The low score makes not any sense.
I‘ll follow up if I get a reasonable reply.

A guy from AMD just said that 5700 XT perform closer to Vega VII in prorender and sometime beat it in that same render engine.

I’m not sure what you mean by this. But Here’s what I’ll say. I work on ProRender for AMD, (check out our blender addon!) . Without Quoting numbers in RPR under OpenCL, render times for 5700XT cards are similar and sometimes slightly better than Radeon VII.

And you can look up Radeon VII benchmarks here independently here: https://www.tomshardware.com/reviews/am ... 977-4.html 41

There are fresh benchmarks (linux) available showing increased performance due to driver optimizations.

As to which design is better all comes down to how they get used: a program that generates lots of threads performing FP32 vector calculations and little else would seem to favor Navi, whereas a program with a variety of integer, float, scalar and vector calculations would favor the flexibility of Turing, and so on.

I wonder how this working for GPU rendering engine. Is RDNA better or Turing ?
