| Already down to $280 https://www.reddit.com/r/buildapcsales/comments/1uz0grn/cpu_... Honestly (apart from the general hardware parts pricing crisis) the problem is that you can get the 7800X3D for almost the same price or just slightly more. Especially if you have a Micro Center nearby you. But it's not bad if you can find a good combo deal with a mobo and RAM, https://www.newegg.com/p/pl?N=4812%204019%204020%204021&Srch... |

| ▲ | hayleyest 14 minutes ago | parent | next [-] | | I assumed a 2 hour drive and used an app that told me population within each zip in a 2 hour drive (the furthest I've driven for one, I drove it 3 times, and every time it felt worth it due to the savings on full builds), and excluded overlaps as best I could. I started at the top, and got through 10 of them before I hit 30% of the US population. There are many to go. MC knows where to put their stores. If you feel this is a worthy debate point, define your criteria better, and I will complete the test with those criteria. But I think this why MC is cited so often. They tend to be where those who want them are. Or close enough. | |
| ▲ | spaceisballer 33 minutes ago | parent | prev [-] | | It’s standard practice on the internet when talking about building PCs to mention Micro Center. Either “it’s cheaper if you have a microcenter nearby” or “this same bundle is $50 cheaper at micro center”. |

| It’s a shame Windows is still so far ahead for game compatibility. Feels a shame to pair such a nice CPU with such a bloated OS. |
| |
| ▲ | vkazanov 44 minutes ago | parent [-] | | "Far ahead"? DRM'ed spyware, yes. Everything else? Not so much, thanks to the monumental effort of Wine and Proton projects. | | |
| ▲ | voidfunc 33 minutes ago | parent [-] | | If you play AAA games with kernel anti-cheat then Wine and Proton are basically non-starters. Cant sidestep that a vast majority of people want to play those games. | | |
| ▲ | vkazanov 29 minutes ago | parent | next [-] | | "Kernel anti-cheat" and "spyware" is exactly what i mean. Thry do have millions of players. But that's like 20-30 games out of 1000s that run just fine. | | | |
| ▲ | Altern4tiveAcc 20 minutes ago | parent | prev | next [-] | | > If you play AAA games with kernel anti-cheat then Wine and Proton are basically non-starters. Kernel-level spyware, and Wine/Proton are the non-starters? I don't think you and the person you replied to will reach an agreement. | |
| ▲ | vablings 20 minutes ago | parent | prev [-] | | Let's rephrase that statement. My game probably works fine on linux and if it doesn't there is an active community read to support it BUT the person, I purchased this game from said no. |

| A shame the x3d cache parts lack integrated GPUs. The extra cache could be handy for inference with smaller models. |
| |
| ▲ | Mashimo 2 hours ago | parent | next [-] | | Newer models do have both the x3d cache and integrated GPU. For example AMD Ryzen™ 7 9800X3D | | |
| ▲ | yakz an hour ago | parent [-] | | The 9800X3D iGPU is definitely handy in some situations, but I tried using it with a 4K wayland desktop for a little while and the performance is really not good enough just for that, unless you're OK with some sub-60hz redraw. I was hoping that the driver situation would be better than Nvidia (lots of issues failing to come back from sleep/unlock). The driver was more reliable but I couldn't live with the occasional choppy redraw. It's really not the kind of CPU that you'd buy and expect to use without a high-end GPU anyway. |

| ▲ | petra 2 hours ago | parent | prev | next [-] | | I wonder what perf. this cpu can get in bit/ternary inference, and whether the 512AVX units(or whats it's called on AMD), get throttled. | | |
| ▲ | wincy 41 minutes ago | parent [-] | | I’ve heard that AMD chips generate a ton of heat with AVX512 operations, overclockers turn off the instruction set for more stability. | | |
| ▲ | adrian_b 5 minutes ago | parent [-] | | Any CPU generates more heat when it does more work, e.g. when more cores are active, or when using vector instructions. Using the AVX-512 operations is much more efficient, i.e. the same amount of work can be done by consuming less energy. For instance, if you have a program running an AVX computation on 4 cores, you could double the throughput either by using AVX-512 or by using 8 cores, but the former variant will produce less heat. For an overclocked system, where the normal power limits of the CPU are disabled, so it can consume a power great enough to exceed the capability of the cooler, it may make sense to disable AVX-512, for fear that one could run accidentally some program that is aware of AVX-512 and which would achieve a greater speed by using it, while also exceeding the power consumption that can be handled by the existing cooler. On the other hand, on a non-overclocked system or in an overclocked system with a very capable cooler, disabling AVX-512 is always a mistake, which can only increase the average power consumption. |

| ▲ | izacus 36 minutes ago | parent | prev [-] | | Caches take die space. GPU takes die space. People buying gaming CPUs tend to not really want iGPU taking away thermals, so it makes kinda sense? | | |
| ▲ | nopurpose 30 minutes ago | parent [-] | | X3D cache doesn't take die space in traditional sense: it is a separate silicon packaged by stacking. |

| It feels like the people doing the benchmarks are stuck in time. POV-Ray benchmarks but not AI? Most people today, including enthusiasts, don't even know what POV-Ray is. |
| |
| ▲ | etiennebausson 2 hours ago | parent | next [-] | | It's a gaming chip, literally a lower-cost downgrade of an AI chip meant for gamers instead of AI. Why would it benchmarked for AI in these circumstances? Beside, the second page look like those unnecessary AI benchmark to me. I wouldn't recognise such for certain or be aible to estimate their quality, but it's what their summary say. | | |
| ▲ | glimshe an hour ago | parent | next [-] | | Why would they benchmark it in POV-Ray if gaming is all that matters? People who buy computers may have a primary use for them but it's useful to know performance in their secondary workloads. | |
| ▲ | speedgoose 2 hours ago | parent | prev | next [-] | | Actually it would be very interesting to know how it performs for AI and whether it has a better value. | | |
| ▲ | etiennebausson 2 hours ago | parent [-] | | I understand where you are coming from. But as a gamer who hasn't been able to make a significant upgrade to my rig in 6 years due to memory price and redirected processor engineering funding (all of it due to AI), it really bother me. | | |
| |
| ▲ | dist-epoch 2 hours ago | parent | prev [-] | | It's not a gaming chip, it's a desktop CPU chip. Imagine thinking that all people use PCs for is games... | | |
| ▲ | smolder 2 hours ago | parent | next [-] | | I assume they meant that gaming is the main market segment it serves, which from my understanding is correct. The X3D chips have great performance in games, which are generally constrained by memory latency. It's, of course, still a general purpose CPU that can do many things. | |
| ▲ | Mashimo 2 hours ago | parent | prev | next [-] | | It is indeed a desktop CPU chip, but the 3dV cache is real good for gaming, thus it's also marked in that region. From the official AMD website: > Whatever the setting or resolution, lead your team to victory with elite gaming performance from a powerful 8‑core AMD gaming processor featuring AMD 3D V‑Cache™ technology. | |
| ▲ | etiennebausson 2 hours ago | parent | prev [-] | | True, I suppose it is also useful for video editing and other uses. The article describe it as a gaming chip, though. Might be because of the site's target audience? I don't know them. | | |
|
| |
| ▲ | Mashimo 2 hours ago | parent | prev [-] | | What kind of AI benchmarks would you like to see? | | |
| ▲ | glimshe 2 hours ago | parent [-] | | I don't know because I'm not a specialist in benchmarks. The article authors are supposedly specialists, so I'd expect them to identify appropriate benchmarks to make statements such as "while this is a good value for games and general purpose use, it fails for local AI as these benchmarks show", for example. |
