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.

It's not a gaming chip, it's a desktop CPU chip. Imagine thinking that all people use PCs for is games...

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.

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.

> Might be because of the site's target audience?

Yes, but also because of official AMD marketing:

> with elite gaming performance from a powerful 8‑core AMD gaming processor

I would also call it a gaming CPU, because it is what it excels at. ¯\(ツ)/¯

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.

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&…

> Especially if you have a Micro Center nearby you

Do they have stores in every state? Even assuming they have, seems fair to assume maybe just 3-4% of people actually have a Micro Center close enough to visit, oddly specific tip :p

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.

What kind of AI benchmarks would you like to see?

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.

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.

A shame the x3d cache parts lack integrated GPUs. The extra cache could be handy for inference with smaller models.

Newer models do have both the x3d cache and integrated GPU. For example AMD Ryzen™ 7 9800X3D

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.
