Test your PC's 64 bit capabilities

[Punx223]

It appears that this is a test that the 2990WX is not the best at. I assume it is not using all of the cores.

Its using all the cores its just the overall RYZEN efficiency is not that good at the compute task it's testing for DP. as you can see from the other RYZEN results including the 2600 above and my 1950X..

Dammit you beat me to posting my 2990WX result -_-

Or, this supports AVX 512. It does say the CPU test is run in native machine code so it wouldn't surprise me.

Fair enough. How does your 2990WX compare? Mine isn't the best clocking chip thanks to the weak motherboard VRM section.

im finishing testing the 1950X on several coolers then she goes in.

I have a X399 Tai Chi and a X399 Gaming 7 to try on... so the VRM on both are plenty capable, but tbh at 4.2ish is about the limit for most of the 2990WX I have seen/used. thats the most common stopping point for most 2nd Gen Ryzen dies.

I overheat the taichi one even with active cooling on it. I don't know that I would call it plenty capable.

Thats wierd.. I have the full-size Tai Chi board and it does rather well with my initial 2990WX testing.. I will definitely let you know with my retail chips how it goes.

It isn't awful, but it definitely is starting to cut it close. Power off is normally a few hours into heavy use. System is in a case however with two hot 1080Ti's that really need to be watercooled. So I do have more heat than a standard user. Problem is gone with the side panel off. It probably would be fine if there was a better cooler for the board. I did not have this issue with my Asus X99m board with its nice finned HS for the MOSFETs

Once Im back from the dead I will post, im currently in limbo

Performs as advertised (7.1 TFLOP):

So, please post your double precision figures.

Virtually nothing GPGPU uses double precision so NVIDIA/AMD have gravitated away from it. The highest double precision cards, AFAIK, are second generation GCN cards which have a 2:1 single:double rate. AMD made the double precision compute power available...and no developers really took advantage of it. Come fourth generation, well, you can see how little double precision is worth in 2018. They will do it...lazily (16:1). Pascal is even worse (~30:1) and so is Turing (~32:1)

You referring to the 7950/7970?

290

290

Pretty sure Tahiti was also half Double Precision.

Edit: Tahiti was GCN V1, R9 290 was Hawaii GCN V2 but I thought GCN V1 did have half DP.

 

[micropage7]

hahaaaa.. just having fun
actually not bad for old school stuff

 

[Voluman]

I have some more with i5-2500, xeon e3-1240, with some of these vgas and various laptops if someone interested i can post more.
Sorry if it too much

You're right, and it's 1:4 not 1:2. Hawaii/Grenada dropped to 1:8.

I wrote "LIKE 128 bit" meaning apps will be slow as hell

Quantum computing is still very far away from the efficiency of binary for executing code though. And it may never get there. Its not a 'better' computer, its a different one, that opens up new possibilities. One of the things it is extremely good at is cryptography, so yes in terms of security it will be a game changer. But for playing Crysis? Nah.

Here is my results....hmm interesting to see that RX 480/580 getting better results in double precision then GTX 1080...

It's all about the DP FPU ratio, 1:16 vs 1:32.
