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.

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.

speedgoose2• 10 hours ago

Actually it would be very interesting to know how it performs for AI and whether it has a better value.

dist-epoch• 10 hours ago

It's not a gaming chip, it's a desktop CPU chip.

Imagine thinking that all people use PCs for is games...

glimshe3• 10 hours ago

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.

What kind of AI benchmarks would you like to see?

glimshe3• 10 hours ago

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.

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

petra• 10 hours ago

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• 9 hours ago

I’ve heard that AMD chips generate a ton of heat with AVX512 operations, overclockers turn off the instruction set for more stability.

Mashimo4• 10 hours ago

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

yakz• 9 hours ago

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.

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• 9 hours ago

X3D cache doesn't take die space in traditional sense: it is a separate silicon packaged by stacking.

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...

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

spaceisballer• 9 hours ago

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”.

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.

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.

vkazanov2• 9 hours ago

"Far ahead"? DRM'ed spyware, yes.

Everything else? Not so much, thanks to the monumental effort of Wine and Proton projects.

voidfunc• 9 hours ago

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.

Win10 iot ent runs on even 3rd gen i3s very well...

rbanffy2• 52 minutes ago

Not sure whether games will run well on it.

DiabloD3• 3 hours ago

A lot of games no longer run properly in Windows, and the only way to keep playing them is with Wine/Proton.

Windows performance is also often worse than Wine/Proton's.

Consider the 7600x3d also if you're in the market for something like this. It has a slightly higher base and boost clock, and half the TDP. It's 6 cores instead of of 8 but if you're building a gaming machine that may not make a big difference. If you're putting it in a small form factor the lower TDP might be helpful.
