AMD Ryzen 7 7800X3D

[Daven]

Alright lads! W1zz has done it! I am buying 7800x3d!!! I was surprised to see it even handily beat out 7900x3d in this game. 7800x3d is def the winner of this CPU gen, and I would go as far as to say its CPU king this generation. It's even giving Intel a run for its money in age of empires 4 and spider man

yep, I am buying 7800x3d day 1. this is my stop. and I might just go yolo and get me that sapphire nitro 7900 xtx that is on sale for $1029 locally. my Ultima rig is almost complete!!!!!!!!!!

I might be joining you on the CPU side but I already bought a 7900xt because all xtx’s at the time were sold out for weeks.

Do people actually bother trying to run anything above 6000 on Zen 4?

How are we supposed to know that there is no improvement on memory overclocking with these x3d chips and new bioses. Secondly, you are running 36-36-36-76 timings on your memory kit when cl 30 kits are widely available; is that because you can't get it to boot with tighter timings or is that the only kit you have for testing?

I am also confused by the overclocking section of the review, it says the cpu is artificially limited to 5050mhz on each core, does that mean the curve optimizer doesn't increase the max clock rate on the cpu?

I will be ready to order this the second it goes up for sale tomorrow.

Same. Already got my 7900 XTX ordered just now. Time to build my dream rig once and for all.

I could really end up hating having a power junky like Intel's big boy on my desk.

Incredible!!!

Looks like a piano.

7700X is still an awesome gaming cpu don't let PC elites tell you otherwise.

A product is only as good as its price.

With hindsight, given the fairy tale lifespans users have received from their AM4 moboS, few would regret any AM4 premium.

Yet even with this example, & and the same situation now (~no future Intel cpuS vs 5+ years of busy AMD roadmap), there seems no end to the trolling on this.

It seems an economy vs the cost of a premature new rig.

It is trolls clutching at straws IMO - Intel have little else to appear better at.

Seems like a very promising CPU in gaming performance with the 3D cache, although it still finds itself with the flaws that 3DV cpus provide, like falling a bit behind in productivity applications and having more thermal constraints.

 

[TTPPUU]

Definitely getting this CPU - my only question is about the EXPO timings and stability

Should I get DDR5-6000 CL36 like in the review or DRR5-6000 CL 30/32 ?

1) Do the tighter timings even matter for gaming performance here?
2) Will 6000-CL30 be 100% rocksolid stable ? CL30 vs CL36 at same 6000 speed is a difference. I've read that Zen 4 CPUs can have some issues with stability (or even just booting) with EXPO 6000 enabled. Would like to know more if possible.

Not really Athalon 64 was also faster in productivity which is what really matters for mass sales, gaming is sort of a by thought. X3D is largely a curb stomp in an edge case, gaming, while being worse than not only intel but AMDs own offerings in everything else.

X3D is going to shine and show it's real teeth in the next generation of consoles.

K8 Athlon 64 was also fast for games.

K8 Athlon 64s have 128-bit FADD SSE and 64-bit FMUL SSE hardware implementation while Pentium IV has high clock speed 64-bit SSE hardware implementation.

Core 2 has the full 128-bit SSE hardware implementation for both FMUL and FADD units and quad instruction issues per cycle rate. K8 has three instruction issues per cycle rate.

I use G.Skill's F5-6000J3038F16GX2-TZ5NR (CL30-38-38-96) modules with manual timing on both ASUS's TUF X670E Wifi and ROG X670E Hero motherboards.

The above manual timings are OCCT memory tested.

 

[PenguinBelly]

How can you compare application performance with CPUs that have like twice as many cores? How can performance in this scenario be considered a huge downside when you're not even comparing apples to apples? That's a bizarre conclusion in my eyes.

$$ is the king.

 

[Minus Infinity]

Only thing that is amazing is the power efficiency. This is the only reason I'd buy it. It makes RL look pathetic. Honestly 7700 looks awesome and still plenty fast for gaming.

What's the average gaming improvements with X3D if I'm using a lowly 3070/3080/6700XT/6800XT and not a 4090 say at 1440p?

 

[Bensam123]

@W1zzard in regard to your core parking problem. Did these cores show up as parked in Resource Monitor like they normally do or was this some sort of behavior outside of that?

I have a 7950X3D and I'm having problems with all 8 of my cache cores being utilized in OW2. My 13900k prior would utilize all 8p cores in W11 and my 5900X would utilize 8 of the assigned cores in W10, however it refuses to use that 8th core. It's the slowest of the 8 cache cores and I assume this is a CPPC problem, but there is no way of shutting off CPPC to verify this, at least on my motherboard, they removed the option to disable it.

All these X3D chips have beta product vibes out the wazoo.

That gaming performance with the 4090 is... m-mm!

I just wonder if it's worth upgrading from a 7700X with a 6750 XT and 1080p monitor. Probably not.

only if you could sell the 7700x for a decent price, which will be hard to do. the cpu market has crashed pretty hard.

And they said "Moore's Law is Dead". Yet here we have a CPU that slaps around everything from Team Blue, at half the power usage. Chapeau, AMD.
Now let's hope AMD reallocate the smart people to the GPU department to sort out the high power consumption over there.

Just did some power costs calculation, and if you game 3hrs/day you have the 60 bucks back in your pocket within 2 years. And of course lower noise and less heat in your room. Savings will differ if you game more or if your power costs are lower/higher. Just calculate it yourself here: Energy cost calculator

MSRP at 499€ was expected. The 13700K launched for 539€, the cheapest one you can get now for 444€, roughly 5 months after launch. So prices will go down after the early adopter rush dives.

Do people actually bother trying to run anything above 6000 on Zen 4?

Faster than DDR6000 is only a Intel thing, nothing to gain on AMD here. But I noticed the CL36 RAM kit you used hasn't the best timings out there. Hardware Unboxed" used a CL30 kit and got quiet some performance gains: How To Cripple Zen 4 In Gaming Benchmarks: AMD Zen 4 vs. Intel Raptor Lake Memory Scaling

The AMD reviewer's guide mentions the following under "Known Issues":

Reviewers may encounter low scores when switching directly from the Ryzen™ 9 7950X3D processor to the Ryzen™ 7 7800X3D processor without reinstalling a fresh version of Windows OS. This is likely a result of the AMD PPM provisioning file driver still being applied to the Ryzen™ 7 7800X3D processor, which was not its intended use. This performance issue is not a typical end user scenario and is only a result of switching CPUs without installing a fresh version of Windows OS.

Though it will not affect a lot of customers, it's still a strange behaviour. Would be interesting to know where the driver is stored. Pretty sure there is a way to remove it manually.

Did you try to remove the CPU from the Windows Device Manager and reboot? Worked for other hardware before for me. Could also be that it's hidden in the Windows Boot Partition. But even for that there's a solution. Just do a drive backup of your OS drive, reinstall Windows & then restore the Windows partition (without the boot partition!). That's also the way how you can get a working restore on a new drive when the backup software is cancelling out because the drive do not match.

Long boot times (fixed on some motherboards) I've been complaining about extremely long boot times in previous Zen 4 reviews, and they are still unreasonably slow. While some vendors, especially ASRock have made great progress, things on my ASUS board are basically unchanged. They've added a "Memory Context Restore" BIOS option a while ago, which reduces the boot times to acceptable levels. Unfortunately on the newer BIOS versions enabling MCR will result in random blue screens in Windows, especially when the machine is idle. I'm not sure why AMD isn't implementing a universal approach to address this, instead relying on motherboard vendors to cook up their own solutions.

Would love to see a AMD "Boot Times" Motherboard Roundup review. Let's see who did their homework. Pretty sure if there is a substantial difference in bootup times from board to board it would influence quite some purchasing decisions.

I am really concerned about motherboard pricing and the longevity of the CPU with that hard voltage limit. What's more, there's no room for overclocking (not really an enthusiast part) and it needs tinkering to achieve maximal performance

Is that you, Ryan Shrout? No worries, prices for mainboards will come down even more. It's just a matter of time.

And in case you missed the memo, overclocking is dead since Thermal Throttling is a thing. It will just boost till it hits max. temps. Same goes for GPU's nowadays.

 

[R0H1T]

OCing even on Intel's been dead since 9900/10900k when Intel pushed the chips beyond reasonable limits! At this point people should really stop complaining about lack of OCing headroom on AMD (or Intel) unless they like running mini ovens in a smallish case

If you're referring to me, this is while using process lasso and something I've used since I've owned a 5820K.

It's being allowed 8 cores and will only load 7 of the 8 cores. On a 13900K it loads 8 of 8 and on a 5900X, it also loaded 8 of 8 assigned.

 

[R0H1T]

Have you tried setting the CPU affinity with OW2 to use all/only cache cores? Then there's also this ~

Quick CPU Advanced CPU settings

Quck CPU Advanced CPu settings

coderbag.com

Which is even more advanced but uses windows hidden/inbuilt settings.

 

[Bensam123]

That's with manually assigning cores through process lasso for the third time. Second app is for overclocking or messing with boost, not affinities or thread scheduling.

Tweaks aren't going to fix this unless you know of specific registry settings to disable or change CPPC cores.

 

[R0H1T]

The second app is for registry settings, it exposes core parking/unparking & boost algorithms among others.

This is on my laptop but you would get similar options on desktop as well ~

 

[Bensam123]

Yup, I don't have core parking enabled. Boosting is part of OCing and unrelated to what I'm talking about.

 

[chenzhen]

x3d,the best for gamer. I want 9800x3d at 2025.

 

[W1zzard]

It is time to up your game and include frame time data of some kind or 0.1% lows. I do not care about average FPS.
