AMD CPU's worse at raytracing?
- Thread starter NirK
- Start date
You read someone not showing any working and you're going to return half a grand because that convinced you about the performance of a cpu that isn't even out yet.
On the other hand, it is dumb to buy anything before seeing benchmarks.
I usually wait for reviews before buying PC gear , its more hassle to send stuff back if DOA after the 30 day window passes just say if board or ram are DOA and 30 days have passed ? have to deal with the manfacture instead

This is true. My 13900k rig, with all other components identical, idles ~20w lower than my R5 7600 system.
I'll be ordering a 7950X3D on release, I expect that overall (when considering gaming & my work/idle use) I'll still use less power, as the 7950X should be very efficient in games.

He clearly only plays one game.

I think it was said tongue in cheek.

I was only joking. You could make a post cherry picking the games that get a better AMD result and say the same thing about AMD. I did pre purchase some components but can always return them if the reviews of the 7950x3D are bad.
no they dont, when the core parks the system shows the last know core speed.
this as been known since first gen
I ran a 5900x as an all in one PC/server and at the wall power generally idled at around 80-100w for full system. I decided it was using too much power when doing server duties idling, so I built a separate 8th Gen Intel i3 system which idles around 25w at the wall. It's not a like for like, but just an example from experience. I have no reason to slate either, just saying. I have a few Ryzen systems in the house and an Intel one. I thought Ryzen generally was still not able to compete as a platform in terms of idle power usage. I don't mean just the CPU, I mean including the motherboard platform all up and running as well. This is one of the reasons b550 was preferred over x570 I thought as it used 5-10watts lower on the motherboard. I may be out of touch on this though.
No really the 5900x pulls more power. I'm shocked.
My 16yo as a 50cc scooter and my 2.5l bmw uses more fuel....

my point is if it pulls 25w at the wall you can compare them.
if they had the same drives, fan, RGB crap, GPU and so on then yes... but that same system docent pull 25w at the wall.
the 5900x at idle pulls 31w so the other 69w was other crap in the system
8th gen i3 8350k Power Draw Idle (Watts) 39
so fitst lets call SB on that 25w total system but lets also ask where is the 69w of other system crap?
comparisons like this down work, cant work.
TBF at first i thought if he as a 12th U chip with 1 ssd 25w is doable. but thats not the same is it. it like me saying my system idles at 90w then comparing my laptop its just not the same.
take as i9 and a 5900x, same GPU, HDD's/SSD's, fans, PSU and so on. the numbers are the same.

You're right, it isn't that meaningful to compare completely different systems, but it is widely recognised on NAS & server forums that Intel idle power is superior to Ryzen (except for APUs).
It depends, of course (on the motherboard and CPU-gen), but they're often not the same. If you take an i9-9900, or i9-10900, I'd bet money that it will have lower idle power than a Ryzen 5900X on X570. 8-9th gen is generally accepted as the best, 10th was a bit worse. I'm not sure on 12th and 13th gen because they have a different architecture.
From what I saw, Ryzen has a few things that make idle power considerably worse, one was running memory above 2666, another was the behaviour of Windows/apps, since some can prevent the CPU from reaching a low-power state which has a bigger impact on Zen than Intel.
and this i accept but for him to claim that a full system pull less power from the wall than what the CPU it rated to idle at...
if i was a general jo on a street and some said a i3 pulls less power at idle that a 5900x i say yep... but thats also true that an i3 pull less pawer than a i5, i7 and i9
so we all stop buying the full AMD line up and 90% of intels chips and just buy i3's.... or peniums what about the N chips
i assume @jaybee is gaming at 4k? or video encoding.
all the chip are out there for a reson... if you was using a 12c24t CPU that can be replaced by an 4c/4t then you was using the wrong chip... your wrong not the chip

I don't know if this remains the case for 12th-13th gen, but for 8th-10th gen, the i3 does not pull less power at idle than an i9. I know it sounds weird, but even a Celeron uses the same power (give or take a few watts) as an i9. Skylake CPUs were very, very good at shutting stuff down.
25 watts is easily achievable (especially without a DGPU) for 8th/9th gen systems, I have a 9th gen system that draws 13 watts at the wall (and that's with an old bronze ATX PSU) and an 8th gen system that draws 23 watts (with a DGPU). Ryzen systems tend to be about 20-30 watts more at idle, depending on how well they've been tuned. The APUs are a different story (maybe because they're a mobile architecture, idk), they can actually match Intel.
My 8th gen i3 server I'm looking at right now plugged into a killawatt and it is reading 24.5 watts. This is running unraid with Plex and a couple of other dockers. Disks spun down. 16gb of ram. Stock heatsink fan. 430watt PSU. 2 x nvme drives and 3 hard disks but spun down. 3 X case fans.
Same unraid install on my Ryzen 5900x but with a few more case fans and a dedicated graphics card and it idled around 85watts.
It's just how it is.
but that all i was getting it buddy, FANS and a GPU dont run at 0.
its no brainer it users more power but remover the GPU and fans your going to be at say 50w?? for the massive difference in CPU power. i dont think thats bad.
but if the i3 dose what you need then no matter what thats the CPU you should have even if the 5900x ideas at the same power, for plex i used a 4th gen i5 i could prob get away with a 4th gen i3.
Basically if you use PC at idle all of the time, intel is cheaper, the more you use AMD at load the more you save compared to intel. Because AMD is a lot less power at load.
Anyway anyone have any more info on AMD regarding ray tracing? Maybe spiderman is an odd result and overall there is not much of a problem, just a bit offputting when AMD is scoring massively lower compared to intel in that graph. I am not sure the difference in cyberpunk is THAT much, most other stuff AMD is around intel level. Hopefully the X3d will end up beating intel it looks very interesting.
