There's some problem with the score database. There are more than 50 scores, but I can't find a button to change page.

First shocking conclusion:
A properly overclocked $1000 Threadripper 1950X @ 4.1GHz (https://www.kraytracing.com/kraybench/?b&publicid=50&lang=en//url) is only 30% slower than a $5000 Dual Xeon(R) CPU E5-2699 v4 (https://www.kraytracing.com/kraybench/?b&publicid=41&lang=en//url) :shock:

My Second conclusion:

I have an i7-5960X @ 4.3GHz, and a Ryzen 7 1700 @ 3.7GHz config.
Under Cinebench, they score exactly the same, around 1600 points.
But in this test, Ryzen seems about 10-15% slower than the i7!

Kray 3 performes better with Intel cpu-s?! (if we assume an AMD and an i7 config with equal cinebench scores)

I noticed also paging error. Will send to G. mail.

Answer can be complicate for me:
- Cinebench is very basic tester (I think there is no even Global Illumination, just simple raytracing - correct me please if I am wrong) So there is no phase for shooting photons, precompute, QMC sampling.
- K3 Benchmark uses the newest technology with a lot swapping information between CPU and RAM (or between CPU - CPU : dual system which is very difficult to handle), optimization scene by making blocks in RAM, etc. This procedures needs reload CPU codes, moving a lot data. Everything for faster rendering.
- PPM phase on fast computer can be so fast that CPU barely get full throttle. When they takes full speed in next moment they must switch to another task with shooting photons phase. We can NOT make longer benchmark because that test with old computer can takes forever: hello this is PPM system with brute force sampling and 16 passes of AA! with full reflection blur and without specularity ...that scene is really heavy for rendering!

I think your difference scores comes from PPM and hardware. Intel probably better (faster) transfer data between CPU and RAM or CPU - CPU. Probably This can NOT be visible in basic benchmarks - they are too simply.
This is nothing wrong, it shows that even motherboard or RAM has influence for time render. I will send mail to G. to ask because he knows how it`s work from the roots. I will back here with answer.

Thanks for testing!
BTW
RYZEN Rocks even is is a bit slower...is much cheaper :)

We have here two exactly same hardware: Dual Xeon 72 threats with same motherboards, new one is...3% faster :P
Probably because new one has the newest Intel Chipset and RAM memory.

I am not sure (Will ask G. also) but G. mentioned about new Intel instructions which we use in Kray 3.

hey think its normal. cause he has 2.6 ghz and mine is like 2.2 i didnt too overclock them. i can go up to 3.6ghz :D .

i will try new one on fresh new Windows 10 installtion for 2nd workstatoin .


as you can see. in my second Workstation i got score better then first. cause when i run that benchmark. i was lunhing many apps : Illustrator. photoshop. chrom with many Windows. lw and modeler and other all in one time . and i did that benchmark thats why in 2nd computer i got more score cause its fresh new Windows10 inslation . :mrgreen: ty

Thanks.

I run it on my S8+ (it took very long) but when it came to an end application just closed. There wasn't any score or anything.

Mobile phones are not rendering machines 8)
Mobiles has low frequency CPU, no HT, small amount of Cores (8 core means 4xlow and 4 high frequency), everything to save energy and not to burn.
In mobile version we do not have window preview - only shell.
I am not sure how far G. will go with mobile benchmark.
I can't run this on my tabloid Galaxy S4, maybe too old Android.

Thanks.

I know it's not a render machine but i was curious about the score :)

Any chance to have also iOS version? New iPhone 8 seems to be very fast.
