Ryzen 7 7800X3D

I'm a senior Rails dev who started self-hosting AI models on my own GPU (7800X3D + 4070 Ti Super) last year. The key insight was building a shared GpuJob base class (130 lines) that handles Redis-based GPU locking, retries, and health tracking — every tool inherits from it, so adding a new one is about 60-80 lines of tool-specific code. The agent workflow (Hermes running in Discord) is where it gets wild — I voice-message an idea and it builds the feature, commits, pushes a PR, and deploys on merge. [...]

I ended up with a 3090FE card, decided to build the first tower I’ve built in years. Opted for and 7800x3d, didn’t realize what a dope chip it was. It was just a better price point than intel - I think 2022 or 2023

Same. Was immediately worried since I bought a 7800x3d for a “too good to be true” price off Aliexpress earlier in the year that works flawlessly and appears to be the real deal.

[...] Performance simply isn't better than Ryzen APUs running in the same power envelope. [...] Further, some of Apple's choices - bringing memory on package, only two display outputs - caused regressions for their users compared to the previous Intel offerings. [...] They licensed ARM's instruction set, Imagination's PowerVR GPU, most of the major system busses (PCIe, Thunderbolt, USB 3, Displayport, etc), they bonded chiplets together with TSMC's packaging and chip-to-chip communication technologies, and they made extensions (like optional x86 memory ordering for all ARM instructions which removes a lot of the work of emulation). [...] And as regards noise, I never hear the fans on my 7800x3D / 3090Ti, and it is very very noticeably faster than my M1 Mac. [...]

My computer is not even one year old and my 7800x3d is already two numbers behind? Wow. Turns out it was all a waste because I haven’t played anything anyway, being an adult and all

[...] I've had my xps 13 since 2016. [...] Now, I've also built an absolute beast of a workstation with a 7800x3d, 64gb ram, 24 gb vram and a fast ssd. [...] Is my old xps slow enough to annoy me? [...] Youtube has been sluggish to load / render here lately but I think that's much more that google is making changes to make firefox / ublock a worse experience than any fault of the laptop.

[...] I have a Ryzen 9 7900X which I bought last year and that is 12 cores/24 threads. [...] Neither the 7800x3D nor the 7900x3d have 16 cores. [...]

They definitely do it some, like Starfield came out with FSR out of the box but they didn’t add DLSS for several months. I got Starfield for free when I bought my 7800X3D which was a nice bonus. Definitely to a lesser degree than Nvidia though.

I have a PC on the other side of my wall from where I'm sitting with a 7800X3D and an nvidia 4090. It's for gaming only most of the time, though I do take advantage of the 4090 for some basic LLM stuff, mostly for local audio transcription and summarizing (I take a lot of notes out loud, I speak faster than I can write). [...]

[...] I'm a heavy user of o3/GPT5, Claude Opus/Sonnet and Gemini 2.5 Pro, so my expectations were sky high. [...] The Qwen model even uses a tiny 1.7B "draft" model for speculative decoding improving performance. In my 7800x3D, RTX 4090 with 64GB RAM, I have latency of 200-400ms, and 20-30 tokens/s which is plenty fast. [...] I always felt uneasy letting Claude Code, Gemini CLI or Codex operate outside my code folders. [...]

[...] Ryzen definitely caught my interest when it first came out, but Intel still had the edge in performance and stability back then, so I stuck with them. That started to change with the 7800X3D, and now with the 97/9950X3D lineup, AMD is clearly ahead. [...]

[...] They're consumer-level systems - Ryzen 7 5700G, Ryzen 5 2600, Ryzen 7 7800X3D.

You need as much FPS as possible for certain games for competitive play like Counter Strike. I went from 80 FPS (highest settings) to 365 FPS (capped to my alienware 360hz monitor) when I upgraded from my old rig (i7-8700K and 1070GTX) to a new one ( 7800X3D and 3090 RTX)

I have a 7800X3D with 64GB Ram, it's overkill for programming So I've installed proxmox on it to utilize it's resources for other stuff as well For my personal use, I created an Arch VM with GPU and USB PCIE passthrough, all 3 monitors directly connected to that GPU It's so seamless and fast that I don't even feel I'm working inside a virtual machine I have other headless VMs hosted to do other things (opensense etc)

[...] The only real choice seemed to be the 7800X3D for a gamer. [...]

I do wonder if PC desktops will eventually move to a similar design. I have a 7800x3d on my desktop, and the thing is a beast but between it and the 3090 I basically have a space heater in my room

[...] But when I got my 7800X3D, that was the difference between having reached a limit with my Factorio megabase and being able to keep building it bigger! [...]

[...] I'm itching to see how the 9800 X3D (or whatever SKU it is) ends up performing, given how great the 7800 X3D has been.

Just want to say, I'm incredibly happy with my 7800X3D. It runs 70C max like Intel chips used to and with a $35 air cooler and it's on average the fastest chip for gaming workloads right now.

I've a new AMD 7800X3D build with an ASUS ROG Strix board, had Network Manager issues (100% CPU) on Ubuntu but everything works great under Fedora 40.

Meanwhile my 7800x3d and 7900xt sip power compared to the new Intel chips pulling 400w on the processor alone. I also have 20GB of vram future proofing me for some time.

Largely yes, but the 7800X3D ($370-$300 on sale, 120W TDP) still beats the 14900KS since the extra L3 cache is more important than clock for most games: (As mentioned another post here, for even more CPU-intensive games like Factorio, the difference is even starker.) For general mixed workloads (assuming you need more threads), I think the 7950X3D is the way to go - 8 3D VCache cores for similar gaming, 20% cheaper than the 14900KS, generally neck and neck on development workloads but also has AVX512 support, and of course all while using significantly less power (also 120W TDP, 160W PPT - you can do even better w/ PBO+UV or Eco mode). Here's the OOTB power consumption comparison, it's a bit bonkers:

[...] So yeah, I'd not waste extra money on the X variant. (Though for games, the 7800X3D is probably the best of the bunch)

Having just recently built a Ryzen 7 7800X3D CPU based desktop, I was worried I had bought just before a new line came out, but from my reading of the press release, none of these CPUs are considered a replacement for that chip. I think?

[...] Going 9900K in a tower to 5700G in a Mini-Box M300 was revolutionary and a 7800X3D or 8800X3D will blow the doors off that too. [...] I build good systems that have good cost-value (even if they're older/used/surplus) but target just a higher set of capabilities. [...]

So I consider that lack of software to be not very much of a negative in that specific scenario. [...] You asked for an example of AMD not doing software, their pricing is irrelevant. Incidentally, a 7800X3D is faster than the higher tier 7950X3D for general gaming precisely because of the lack of assistive tooling. [...] GeForce Experience has never been worth the CPU cycles it eats, it's just telemetry bloatware. I want easy driver updates because I play games. [...] If that's the case, Windows Update has you covered. [...] I don't consider any of their options anymore, always going Intel and Nvidia, because my time is worth more than that. As far as hardware quality, Nvidia’s best quality and customer service AIB partner EVGA quit the market because of Nvidia’s abusive business relationship. [...] AMD can't do software, which is a damn shame given how capable their hard

[...] They don’t even make one that runs as fast as the 7800X3D. [...] So I consider that lack of software to be not very much of a negative in that specific scenario. [...] I want easy driver updates because I play games. [...] I want to open the app and click a button. [...] As far as hardware quality, Nvidia’s best quality and customer service AIB partner EVGA quit the market because of Nvidia’s abusive business relationship. [...]

[...] You claimed that AMD can’t make software, full stop. [...] AMD straight up does not provide assistive tooling for 7900X3D and 7950X3D's asymmetric cores, this has meant worse performance than the lower tier 7800X3D that doesn't need such tooling. [...] The "AI" world can also tell you all about how AMD simply does not grok software. Nvidia is the overlord of "AI" in large part because AMD simply does/can not software. [...] I also like how I don’t have to login to an account for automatic driver updates like I did with the GeForce Experience application. [...] Regardless of that though, you don't need to login to anything because Windows Update will autoupdate the drivers anyway if you don't opt out. Plus, you can turn off telemetry in AMD software, where that’s not even an option for Nvidia. [...]

AMD CPUs are phenomenal because AMD doesn't have to do much software work (if any) to enable that. [...] 7900X3D and 7950X3D ended up being squarely inferior to the lower-tiered 7800X3D because they could not and would not provide software tooling to assist the scheduler in handling asymmetric cores. [...] Nvidia and even Intel's offerings Just Work(tm), and that virtue becomes only more valuable as I get older and my time becomes ever more priceless.

[...] So I finally upgraded to an AMD 7800X3D, nvidia 4070 12GB, 64GB DDR5-6400 RAM. [...] :D Apart from a strange error where Linux will crash if I have 2 DIMMs in the motherboard, it's been a great upgrade. (I'm going to submit bug reports to Fedora, but I'm assuming some combo of the MSI B650 motherboard, CPU, and memory are contributing to the error. [...]

[...] Their picks are pretty reasonable, but the "highest performance for gaming" category with the 7950X3D and 13900k doesn't make a lot of sense to me, when the 7800X3D which won the "High perf" category beats the 13900k significantly in most games benchmarks, while drawing much less power. Intel has some great value offerings, but the 7800X3D is the real champ in gaming right now. [...]

[...] I have a V850 SFX Gold, a single 3090 FTW3 and a 7800X3D, and its rock solid in OCCT's variable load test, even when overclocked (and its not overclocked on linux). I have literally all the exact same issues on my RTX 2060 Asus G14 laptop, like: - GPU rendering broken in Wayland Chromium/Electron, and sometimes Firefox - Occasional black screen on boot, from some kind of race condition. [...] And I still get some of that when Nvidia DRM is disabled and I'm just using the 4900HS/7800X3D for display out. [...]

[...] Specs are 4090/7800x3d, 64gb 6000c30, 990 pro nvme, bought mostly for being able to run DCS World (and iRacing) on triple screens plus Star Citizen. The 4090 is beast, and absolutely worth it. [...]

[...] This is with a 3080 and a 7800X3D and 64GB of RAM, but wow the game looks really really nice. [...] I bought this one off some kid for $400 and 3090s are selling for $650.

Mid-late game Stellaris still chugs on my 7800X3D, which is massively faster than pretty much any non X3D CPU in this particular game. [...]

HP Elite 8300 My PC (Custom build, RTX 4070 Ti, AMD Ryzen 7 7800X3D, 32GB RAM, W11) My PC My PC But I mostly just use my laptop 💀

[...] According to geekbench 7800x3d is 2400 single core, 15500 multicore. [...] Yet when I convert video using libsvtav1 with ffmpeg I’m getting noticeably faster performance on the desktop. And that’s with mbp, which doesn’t thermally throttle within 15 seconds. [...]

So I have some DDR4 RAM that I should probably just sell because I've looked multiple times at building an AM4 PC and it's just not worth it. [...] Anyway, I just can't find a reason to build an AM4 PC even though the RAM is "free". It's just not worth it. If you need 64GB+ of RAM and the DDR4 vs DDR5 difference isn't significant to you then maybe it's worth it. Otherwise, you can still buy a 32GB DDR5 PC for similar prices to last year sometimes. It's not worth buying any AM4 CPU then the 7500X3D/7600X3D/7800X3D are so much better for the same price. [...] Anyway, the price seems to be $349. If so, that's completely not worth it. It's the same price as the 7800XD, which is significantly better. As an example, here's a 7800X3D + motherboard + 32GB DDR5 bundle you can buy today for $629 if you happen to live near a Micro Center [1]. [...]

[...] On my desktop with a 7800X3D and 64 GB of RAM, I get scared whenever the system needs to do the training again. Because it just sits there at a black screen for a couple minutes while it does the training. [...]

In my experience with a 4070ti (12 gb vram), 7800x3d and 64gb ddr5 it will run… but seemingly at about 0.1-0.5 tokens per second with partial GPU offload. It’s painful, but the results are night and day compared to the models that will fit entirely in vram. Of course perhaps I’m doing something wrong so if others have advice it would be great to hear!

[...] I had to dial back my 7800 X3D to 6000 after rare but consistent crashes. [...]

Are you? I'm pretty sure when I bought my 7800x3d, everybody was saying you had to be very careful about heat, because these damage more easily from high temperatures than regular CPUs. I just checked, and they do throttle at a lower temperature than others: 89 vs 95 degrees C.

Other countries have computer shops too. The one where I bought the components for my current desktop has those CPUs listed, the 7800X3D is only £5 more than the 7700X3D.

If you replaced your M4 with an M5 you'd get more performance but the power usage will go up substantially. OTOH, if you replaced your 7800X3D with Raptor Lake you'll get similar performance for less power. [...] In 2025, Apple chose to increase power to increase performance, Intel is the manufacturer with substantially increased efficiency in 2025.

Thinking selling my desktop PC, I not using it much I been using my laptop, trying think of a fair price. This a custom PC Specs: CPU: AMD Ryzen 7 7800X3D Motherboard: Asus Rog Strix B650E-I RAM: Corsair Vengence 64GB DDR5 Storage: 1TB Samsung Nvme GPU: 1660 4GB Windows 11 Case: Fractal Design

[...] 12 years later, the 586 had 3.1mm transistors, P4 had 42mm, 10 years later (2003) p4xe had 169mm (but a year earlier there were only 65mm in the p4). haswell, ten years later, 1.4 billion transistors. in 2023, AMD ryzen 7800x3d had 6.5 billion transistors. [...]

Yeah. $2K-3K is what my 3090/7800x3D sff desktop cost (depending on whether you include the price of the TV/peripherals I already own).
