Thread to focus on Zen4 3D cache CPUs.

New gaming king (as most expected), though the 2 CCD 7950x3d does seem to have issues with some games, more than I would expect of it getting stuck on the "wrong" CCD. I imagine it will get cleared up with subsequent updates but we'll see. Simulated 7800X3D showed no such issues and overall has the gaming lead (real product might be slightly slower though depending on in game clocks).


Computerbase also has the 7950x3d as the gaming champ. They (and TPU) also show that efficiency while gaming is extremely good.







Just to toot my own horn a little, it landed spot on with my prediction of fastest gaming CPU but not significantly so over a 13900k on average, but with much higher efficiency.

Additional reviews, will add more later.

Possibly stupid question but it I'm out of the loop in this stuff right now, just about to get into an upgrade.
Are any games CPU bound with any of the high end AMD CPUs, 3D or not?
The assumption I'm making here is that you would be using a fairly high end GPU paired with a top end CPU.

As you know I was in the same spot as well. But after seeing the reviews of the X3D parts and how little performance advantage they seem to have over the non 3D parts I'm glad I didn't wait. Unless the 7800X3D behaves differently I just don't see paying almost 33% more for a CPU that offers only a few % more performance.
Normally I would agree that the average increase is not worth the extra cost, especially for me playing 5120x1440, but for some weird reason the fact that it in some games perform a lot better and in others about the same as the 7700X has a psychological effect on me wanting to buy the 7800X3D.

Except that it costs more, but it is a price I'm willing to pay.
Hey, you will get basically a free CPU, considering that the CPU will pay itself off with lower power consumption in 5 years and I know you are too lazy to upgrade before that

I mean, you are running a 140W CPU right now and that too, overclocked! Oh no! I wonder how many CPUs you could have afforded in that timeframe if you had stuck to an i7-5775C

I like to keep at least two rigs with the same platform for backup/isolation testing purposes, so I will likely buy a cheap B650 board to house this 7700X when I buy a 7800X3D for the gaming rig. It has also saved me in the past with unexpected hardware failures to get back up and running within an hour.

Whether or not cheap B650 boards are ready for the mainstream remains to be seen. Wouldn't be the first time I reviewed cheap mATX boards for the forum:

There are still CPU bound games. CSGO being one of the most played. MS Flight Sim, Planet Coaster, LoTR Online, and some other sims and MMOs often have areas that are entirely CPU bound as well. Even if you are using a 4090 at high res. Nvidia driver overhead in many newer games places even more of a burden on the CPU.

Other burdens are being placed on CPUs now due to some 9th gen console ports. For example: the Spiderman games require the CPU to do asset decompression and streaming that the PS5 has dedicated hardware for. Then there is ray tracing, which is proving to be hard not only on the GPU, but also on its VRAM and the CPU, in some titles.

The CPU is going to remain essential to higher end gaming for the foreseeable future. For myself, even games like GTA V, Cyberpunk'd, and Witcher 3 are less enjoyable if you can't max all the crowd settings.

You must post your own commentary.

I did some rough calculations. If you save 100 watts vs the competition, and game 10 hours per day, every day, you might save around 50 bucks per year. Not insignificant, but not that much considering you are probably running a 400 to 600 watt gpu at the same time.
(1kwh per day x .15 per kwh x 365 days per year - 54.75 per year) Obviously, that is a very high end estimate of how much gaming a person will do.

My 4090 take less than 300 watts. Where do you get 400-600 ?

@ondma

Fix that post where you quoted Igor please. It has no personal commentary.

As to the power savings, try recalculating for our friends in Europe that are paying much more for it. We have members in Denmark, it ain't $50 for them.

And on the point of 50$. Doesn't matter what else the system is running. Because $50 is $50. Throws the talking point about saving money by buying a skt1700 with cheaper boards and DDR4 right out the window.

Denmark s electricity cost was around 0.45-0.52€/kWh theses days...

I'm paying $0.2-0.3/kWh on average currently here in Denmark. But since I game 4-6h/week it is not going to be my biggest post no matter which system I choose.

My understanding is there's always the options to force the usage of the v-cache chiplet by enabling some UEFI opotions. The follwoing is from the Techpowerup review:


If I were a person who games a lot but for some reason can also use a 16-core CPU, I would simply enable "Prefer Cache" and get on with my life until the automatic scheduling mechanic is perfected. This is exactly what I did with my 12700K, I kept the E-cores off for almost 1 year until Win 11 was mature enough for my main system. Temporarily not having E-cores was a small price to play for a hassle free experience, and I would argue the same applies to not having optimized priority for the non-cache chiplet.

That being said, if I had to build an AM5 system for my needs today, I would not go past 7700X / 7800X3D.

The issue is most older games actually prefer a single fast thread over the extra cache, while newer games prefer the cache. I don't like the idea of disabling half the CPU I paid for at all times, but figuring out what cores to use in what games and setting the affinity is a hassle too. Many older games have issues with core affinity in general. I used to have many issues with old Athlon 64 CPUs and they only went away after I switched back to Intel with the Core 2. The 7800X3D would avoid this whole issue and is also cheaper.

My 4090 take less than 300 watts. Where do you get 400-600 ?

It uses much more in RT games. Metro Exodus is RT and also well optimized and runs at high framerates at native 4K, and it goes up to 500W often there.

You are surely covered by your company s contract that is price limited by the state, businesses support the whole speculation that occured recently in Europe, here in France we once paid 0.125€ just 2 years ago, currently it s 0.175€ for individuals only, almost 50% more in a matter of 2 years...

Nope, it was over $1/kWh when it was highest. My price is regulated by the hour.

I'm guessing that my needs are different! I can't imagine not getting reasonable FPS in csgo with pretty much any new hardware!

No, you definitely will in CSGO. That wasn't your question. For example: Spiderman with max ray tracing is too much for a 11400f to manage 60fps at all times. That speaks to how CPU intensive games are getting. That there are already games that make a modern 12 thread CPU buy a struggle bus ticket.

If your use case is that you can get away with a less than premium CPU, that's great.

Yes, that is quite normal here in Denmark were the usage is monitored digitally.


Anyway price are such that 100W less will amount to 40€ or so per year for your daily usage wether it s in your location or elsewhere in most Europe.

That being said 70-80W less at the CPU level mean more silent PC as well as lower temps overall and lower VRM power, all in all that s more reliability on the long run while the extra cache add some longevity to the CPU since bigger cached CPU proved more capable as softwares and usages increased computing needs with time.

7800X3D official performance slides from AMD released by Tom's Hardware:
AMD Shares First Official Ryzen 7 7800X3D Gaming Benchmarks vs Core i9-13900K, Up To 24% Faster



Reading between the results, it appears to show exactly what we all suspected - 7800X3D will be the gaming chip to get and that's why AMD is launching it later - to avoid cannibalizing sales from the 7950X3D and 7900X3D.

7950X3D may be a few % faster overall, but it's hard to argue with a chip that costs $250 less and doesn't have an asymmetric setup. It also costs $130 less than the 13900K.

April is only a month away...

Cards on the table, I'm trying to decide on the best AM4 CPU. Just pulled the trigger on a good RX6950xt deal.
Obviously the 5800x3d looks like a choice but I'm not convinced that more cores and a higher boost clock isn't going to give a gaming experience that isn't noticeably worse while giving a better productivity experience.
Ultimately I guess that m overthinking it and here isn't a bad decision here.

For AM4 anything 5700X and above is going to be a solid pick. The 5800X3D is the gamer's choice, while the 5900x and 5950X for productivity. Most Zen 3 aside from the 3D can be had for a great price on the used market now.

I run a 5800X in ECO mode with a +200MHz boost for the PBO. It results in just over 5GHz max boost while having a 88W package power limit; 65W for the CPU. Pairs well with my RX 6800. If I had a 6950XT I'd go 3D for gaming. Either of the 59s for gaming and productivity.
