AMD Ryzen 7 9800X3D Linux Performance: Zen 5 With 3D V-Cache

[avis]

Zen5 3D:

1. A blatant rip-off price-wise, "just" $480 for the CPU alone, not counting cooling (and lots of reviewers ran it with liquid cooling/AiO)

2. A pathetic gaming performance increase:



3. A horrible decrease in power efficiency:



AMD fanbase? A wonderful CPU!!! MY NEXT CPU FOR SURE. INTEL DESTROYED AND RECKED!

Reality:

• A pathetic showing vs Apple M4 Pro
• Extremely overpriced; costs as much as Sony PlayStation 5
• Barely any progress in 2 years for the vast majority of people
• A regression in terms of power efficiency despite using a more advanced node
• Continues the tradition of desktop AMD Zen CPUs idling at 25W+

Trump becoming a president again is now not the worst news of the day.

Yeah it really has 2 use cases:

A - competitive tryhard with a 4090 on a 1080p TN

B - beer belly dad with a 4k oled who runs Alan Woke 2 on ultra with RT for 35 mins before having to go back to work.

It doesn't make sense at 480$ for the vast majority of people. And let's not even talk about mobo prices in EU.

I have yet to see my 5700X bottlenecking anything on a 49" personally, I do plan to upgrade at some point but I won't ever pay over 150 for a mobo. 32G 7200 DDR5 price has become ok tho.

[hoohoo]

When I first started using Linux it took about 3.5 hours to build the kernel on my then 386, and that was a much smaller kernel. Less than a minute still blows my mind.

Yep. I was there in year 2000 when taking a week to compile gentoo supposedly gave you an edge. Except benchmarks proved otherwise, and that was time spent you would never have made back even with a 5% perf increase :')

I've been ripping into it pretty hard and I'm as big of an AMD fan as they come. The power results make me make me wonder if the 9800X3D could be reigned in to be made more efficient. Since they're marketed as gaming CPUs and I know that the 7800X3D doesn't utilize 100% usage when gaming, either 8 core X3D kicks a lot of ass for that intended purpose (price not withstanding) so it makes a lot of sense to run them as efficient as possible versus as fast as possible. That's especially true if you don't have one the best GPUs in the world to really put a modern CPU core through its paces, X3D or not.

Trump becoming a president again is now not the worst news of the day.

No shit. Talk about depressing, though I'm not surprised. So many people that don't get on the internet are completely oblivious to anything bad that guy does and the ones that know what he's doing don't really care because they're pretty hateful people. When they're not hateful people, they're just rich.

I was helping a friend with a printer earlier today and the conversation had one hell of a shift

"Trump's never done anything illegal."

"Trump writing derogatory posts on Truth Social about his judges during trial and now that he's a convicted felon out on bail awaiting sentencing were both illegal."

"Boy there sure is a lot of dust in my computer. I bet that dust filter is really dirty."

"It doesn't have a filter. That's just how dirty your computer is...Anyways, you need to buy some black ink. That's why your printer isn't working and what the orange light next to 'Black Ink' means. Orange means it's out and needs to be replaced."

He didn't like that Orange comparison. That then went into some bullshit about how Elon Musk buying Twitter and making Starlink is him being the bastion of restoring freedom of speech, but that transition from specific things he's doing illegal to boy my filter is dirty, , just goes to show how they really don't care about facts and specifics, just thoughts and feelings.

That's when I went into detail about how Starlink is ruining astrophotography, how Musk pulled Ukraine's Starlink service when they made advances towards Russia, and how if you have to pay for Starlink then it really isn't free speech. That was transitioned right back to printer ink.

Anyways, they don't really seem to care about the facts as much as they do their feelings. The guy I was talking to was a 70 year old retired teacher who runs his own business and has over 20 rent houses. He's not dumb. He just sees Trump as better for his bottom line so anything negative becomes justified. The worst part is the majority of the people he rents to are on welfare. It makes him the biggest welfare recipient that I know. He's the welfare queen that him and people like him complain about.

Another thing that blew my mind lately is that doom 3 runs on a very, very low end A53 quad-core arm chip nowadays.

Yeah the game is 20 years old, but still, you had to shell out the equivalent of 2500$ back then to play it well, and now it runs on a freaking 35$ chinese handheld lol

Some of the benchmarks do not make sense
- OpenRadioss (Neon 1M): R7 5950X is slower than 5800X. Is this program not supporting 32 threads? Then, of course 9800x3D almost matches the performance of 7950x
- OpenFOAM 10 (Small Mesh): 9800x3d is beating 9950x? Come on!
- Zstd Compression 1.5.4 (Long Mode - Compression Speed) Again, 9800x3d beating 9950X? That is obviously either wrong, or this benchmark is not using 32 threads. Even 7900x is beating 9950X there. This is not right.

Ok, I am not reading any other benchmarks. I can't follow, doesn't make sense.

[mrg666]

For the same price, I would buy 7950x any day. I don't game at 1080P anyway. At 4K, 3D CPU advantage vanishes.

[geerge]

I agree with you. I think if you run the 9800X3d at 65W, it'll be 4% better than 7800X3D.

That works for me. AVX512 with enough cache that the data being processed stays in cache.

What thread are you reading? Again, no one here said anything close to this and you're just arguing with imaginary people.
