Poll: Ryzen 7950X3D, 7900X3D, 7800X3D

[LtMatt]

Ι don't have the 13900k anymore man, gave it away cause gaming power draw was nuts.

The built in benchmark is useless for CPU performance, it's really light on the CPU, but sure ill do it in the afternoon, g2g now. Below another area you can test

I think I'm done testing different areas in Cyberpunk now tbh, especially as you don't have the 13900K for comparison. I've already done Cherry Blossom Market and now Toms Diner. From what I can see, X3D performance is top notch in Cyberpunk and a big gain vs my tuned 7950X.

Spiderman however, although I see nice gains over the 7950X, it's not a slam dunk for the X3D like a lot of other games are.

I just realised I didn't enable ReBar for the 4090, not sure how important that is in Cyberpunk/Spiderman.

what's really crazy is amd latest dragon range laptop cpu has the same multithread performance as the 7950x3d

AMD really needs to increase desktop cpu core counts now, the laptops are on par with desktop performance and we can't have this it's heresy

My complete noob opinion is **** cores - they need to juice up the mainthread/lead cores and do what architectural **** they can to boost gaming performance. I was more than willing to spend the cash if the benchmarks revealed any point, but they didn't so I just got a 300 dollar 7600x during that december sale.


Games just don't use those cores. I wish they did, I really do.

Maybe someone else with a 13900k can contribute. But honestly the performance doesn't matter, whether the 3d or the 13900K wins by 5% is pointless. The power draw difference is huge, and although I expected the 3d to pull less power than my 12900k, at least it delivers the performance.

Maybe the 7800X3D will cut down on the power draw even more.

Most games don't. Doom Eternal runs well on anything so although it can use every core you have, it's not needed. Only Cyberpunk and Spiderman have a use case for more than 8 cores. All other games (bar Football Manager but that's a different kettle of fish) are happy with 8 or less cores and that will not change anytime soon. Cyberpunk and Spiderman are outliers.

IMO you should wait for the 7800X3D. The 7950X3D, in games that use 8 or less cores, is an unstoppable force with the second CCD physically disabled and that additional cache available to those 8 cores. Disabling SMT in this scenario just allows even more power for that VCache CCD and as simulated tests have shown its pretty fast in this configuration and won't be easily beaten by anything else for some time.

Yes it will, I can see that by physically disabling the second CCD in the BIOS. However, Cyberpunk loses performance here because it wants more than 8 cores at lower resolution with RT cranked up.

Intel has node issues that TSMC has thus far been able to avoid.

A monolithic 5nm or possibly 3nm design would probably perform a lot differently than what Intel is making do with on inferior processes.

There's a lot more than Intel being on an inferior process at play though.

Zen's design is just a lot more efficient than Intel's P cores and while the E cores are efficient they have other issues*.

The hypothetical what-if where Intel port their design to TSMC 7nm/5nm etc. is very hard to answer but for efficiency in terms of power and transistors Intel's design is worse IMO.
Meteor Lake will use some TSMC tiles but for not the main CPU cores one. The only point of interest for Meteor Lake will be perf/power as they are leading with mobile first - we shall see if Intel have any clever strategy to make a chiplet approach which has the idle efficiency a laptop demands.

The irony used to be that historically Intel have often had the opposite: the P4 was a far inferior design compared to A64 but since Intel had a process lead they could hide that. Now Intel are in double trouble: worse process and a worse design.

The additional irony is that for years Intel refusing to take mobile seriously by rejecting making the original IPhone SOC and treating Atom as a product to keep old fabs busy but which should never take sales away from Core; all of that is somewhat similar to what happened to former workstation/server CPU vendors of the 1980s and 1990s - and could be great source of Schadenfreude to them. As they too ignored volume and wanted to focus only on the high-margin stuff.

Watch out AMD: your high-margin "premium brand" strategy only made sense when you were severely constrained by TSMC's capacity the last few years. Focusing only on margins now means that some other vendor gets a chance to go for volume. Once, for example, some Chinese GPU manufacture gets their act together and starts taking the low end both AMD and Nvidia would probably ignore them until they get too big with a low-margin high-volume strategy. While the entry to x86 is nearly impossible, RiscV should eventually get there and then a high-margin only strategy would probably fail.


* For instance, my new work laptop with a 1235U - yes I know only 2P and 8E - is MUCH slower than my old Haswell laptop at pretty much all SQL queries I have run on it: one particularly long query with lots of complex joins and cases takes 35mins vs 11 on the old laptop; turning off the E cores can get this down to "only" 15 mins - locking SQL to the P cores didn't work for me.

7800X3D looking good to me as an upgrade from my 5800X - Will see what the reviews bring - Hoping they dont just kill it by changing boost clocks by -500mhz compared to the 7950X3D CCD with the cache

 

[LtMatt]

@Bencher I just realised I accidentally enabled a +100mv CPU voltage boost in those videos I uploaded. I didn't realise but I had the second CCD at positive offset instead of negative.

I'll put up some new videos without the voltage bump (i intended to use negative offset not positive) and I'll enable ReBar too.

I don't think that will happen because AMD are allowing Curve Optimiser and PBO this time so that would mean they would have to bin the chiplet post 3d cache or simply nobble it with thermal limits... Obviously I know no more than the next person what I'm saying is its unlikely imho.

Just cant see them killing the chance of sales of the 7950X3D for Gamers who want it mainly for gaming, not given their recent business decisions anyway.

I’m assuming they’ve done this only to maintain their lineup hierarchies. Will be interesting to see what kind of difference it makes. I’m hoping it doesn’t impact performance too much as I want to buy one as well.

 

[KompuKare]

@LtMatt You should set up an Onlyfans for benchmark requests.

Well, I don't know about paying, but once you have settled in @LtMatt there's always CAT's FO4 benchmark thread:

Fallout 4 CPU benchmark thread(need some Zen3 and Zen4 results!)

Background A few of us still play some of the old Creation Engine based games such as Fallout 4. Annoyingly a lot of reviewers don't seem to test older games anymore,and these generally benefit the most from better single threaded performance,faster memory speeds,etc. Fallout 4 tends to be...

forums.overclockers.co.uk

you already have the top scoring 5800X3D there but there are some tuned 13700K's above you, so would be great to see if you can beat them!

The top 3 (you, and two 13700Ks) are only separated by less than 1% so should be easy!

A while back id have every confidence it would be exactly the same as a 7950X3D with a disabled CCD - Nowadays i'm not so sure they will do that....They have got a touch "greedy"

they also want people to come to AM5 and really for gamers the 7800x3d is the first reason to do that since its release because the platform is quite expensive.

That bench is such a pain in the ass though mate Lol. I'll give it some thought...

Here's Spiderman with RT for comparison. Please take careful note of the settings and copy them exactly. Then walk down 5th avenue and 59th street towards, 55th street as per the video.

Okay, here are the results for Spiderman, 1440P DLSS Q.

@LtMatt Nevermind, just did this, pretty short run on toms dinner, stock 12900k, im showing everything you need I think, if it's missing something just tell me and ill fix it.

Toms dinner sort test

www.youtube.com

Copied your settings (1080P, Ultra RT + DLSS Q) and test sequence exactly, this time with a 4090 instead of an XTX.

@Poneros You might be interested in the above.

Now moving on to Horizon Zero Dawn and Warzone.

And another site that shows the X 3D faster overall @Harshell123

Well all I do is use cinebench all day and playRainbow 6 sometimes and on my time off Final Fantasy. The 13900k is the best. I win, you lose.

Good day

Yep, won't argue that Cinebench and FF are going to be much faster on the 13900K.

I've got Rainbow Six Siege though, if you fancy a little performance comparison?

 

[humbug]

That attracted a lot of attention. I expect various tech sites will echo it without checking or take a look themselves.

Hardwareluxx looked at the claims, did their own tests and found no meaningful difference between them.

The interesting thing about that slide is its showing performance for the 7950X as if its got a full size iGPU, really?

Oh and CS GO with maybe a touch of Total War Warhammer

I’ll leave the performance testing to the pros. Im sure someone on here will take up the challenge though.

Hopefully someone with a 13900ks with an Apex and over 8000mhz ram
