AMD Ryzen 9 3900X

Post by FarbigeWelt » Mon May 27, 2019 8:31 am

(info read on www.heise.de)

AMD Ryzen 9 3900X, 12 cores, 3,8 GHz nominal (Turbo: 4,6 GHz), 105-Watt TDP. One I/O-chip, 14 nm and two 7 nm octa-core-chiplets.
Availability 7.7.2019, price 499 $.
And 56 mainboards to chose from.

Speed in Cinebench R20 shows 15% plus for single threading and 18% plus for multi threading compared to 2000 series.

This new processor in combination with a new mainboard sounds like a good replacement for my current i7 4770K and my need for more CPU power due to my BiDir addiction. ;-)

Will gracefully leave my 8700k for this one !
Paired with two Navi 5700 will shine like diamond :twisted:

Sure, I most probably will replace part by part with the aim of having to RX 5700 installed. 😎

The only thing that can make me choose Nvidia is accelareted path tracing on Luxcore Via RTX. But currently we don't know much about rt core implementation in renderer like CYCLES EEVEEE or LUXCORE.
We don't know if it will closed like CUDA. We don't know how it perform on GI dominant scene. Most of the time RTX is playing inside game with baked GI while RT core doing reflection and direct light.

__ Nvidia will cost arround 120 dollars more
__ and most of the time with less Onboard memory
__ Closed Cuda and no opencl 2.0 support
__ Luxcore is my favorite renderer and it behave better on Radeon ( screen is more responsive on a poor R9 390 than on a GTX 1080ti while rendering.)

I don't know how Navi will compare to Turing but in a Toe to toe scenario AMD win for me. Don't simply like monopole closed source and overpricind habit (even with AMD Vega 7).

I wish Navi will have good price good computing performance. And better efficiency.

If not twos RTX 2070 can win. But i hope no. 2 competitor is better than single one.

Sure, nvidia is the leader and RTX is a good thing. And before I read some hardware test for the new amd cards I would not decide. It is more a emotional thing at the moment. And I like new technologies like 7nm. I hope TDP of the new cards is on a good value. Let’s see.

Is it already decided that the new amds are 8GB max?

There is no information yet. I don't hope so, otherwise I had to think about Radeon VII (16 GB).

Yes, it is decided. There are two version, both with 8GB.

Radeon RX 5700 about equal to nvidia 2060
Radeon RX 5700 XT about equal to RTX 2070, approx. 8 Tflops.

AMD cards are a bit cheaper than nvidia but they have higher TDP resp. max power, up to 180 W or 225 W for XT.

I have to wait for LuxMark tests to compare the cards‘ speed with the speed of my old cards to make any decision. Factor below three to four would not be enough to make any change
