New Processor Choice

[KungFuJosh]

I'm deciding on which way to go with my system update. UserBenchmark claims the Ryzen is meh compared to either of the Intel chips, but there's trade-offs either way regarding the hardware that goes with AMD vs. Intel. There's no longer any price benefit either. Only the i7 is slightly less.

Ryzen 9 3900XT vs. i7-10700K vs. i9-10900K.

What do you think?

Thanks,
Josh

Impossible to say for sure without knowing your use-case. But it would be hard to separate them.

Most people would never notice a difference either between 8, 10 or 12 cores or between 4.7, 5.1, or 5.2 GHz turbo speeds by just using the machine -- you'd need a stopwatch to separate them, which is more about geek points than any actual need. Compared to 4 cores, sure that would be noticeable. Or compared to 32 cores (which I have in my work machine). But not among themselves.

The biggest difference is probably the 32 MB of L3 cache in the AMD compared to the 16 or 20 MB in the Intel chips.

Pretty much 0 reason to go with Intel nowadays, for almost any use case.

For a time I liked the idea of using Intel so I had access to the AVX-512 instruction set for development work. However, Intel have made such a mess of AVX-512 it doesn't seem to be worth bothering with right now.

None of the listed choices support AVX-512.

And in most cases, if you actually use AVX-512 then the processor clock is slowed by so much for so long that it's simply not worth it unless you did some really serious processing with the AVX-512.

Really? I thought they'd put at least one of the AVX512 subsets into anything called an i9.

Yep, that's why its currently a waste of time for most people. From tests I've seen even code which is really serious about using AVX512 isn't really getting a boost from it.

Nope.  i9-10900X has AVX-512, but  i9-10900K doesn't.

Have a Ryzen 7 3800X and can highly recommend it.  However, you will not get much from overclocking it, if that is something that bothers you.  I had stability issues at 4.4GHz when stock turbo is 4.2GHz.

I wish more software was x86 independent. Probably the next gen of Fujitsu A64FX will contribute to wipe out x86 once for all.

As for me, choose[ Ryzen9-3800XT, i7-10700K, i9-10900K ] ---> Ryzen9-3800XT

Why do you believe this? I'd love some examples. UserBenchmark still puts Intel fairly consistently above AMD. There's also no price benefit, the Ryzen costs more than the i7 which outperforms it.

I like the idea of the PCIe 4.0 support, but it will be a LONG time before I get anything that actually benefits from it...and Gigabyte's Z490 boards have the hardware to support it in the future.

[KungFuJosh]

My uses are mostly creative. Web and graphic design, photography, video production, audio production. For example, the Adobe suite, Vegas Pro, Presonus Studio One, Samplitude, kicad, Capture One Pro, Visio, etc... The other stuff I do won't care about the upgrade, and the only game I play is Rocksmith.

My current system is based around an i7-5820K with 32GB of RAM. I'm just swapping the chip, board, and power supply (and a new AIO cooler).

Thanks,
Josh

Only if an affordable version of it becomes widely available. That was the main reason AMD was successful with their 64 bit architecture - make it affordable so it can gain market share. (The other big reason was working with GCC developers to get a supported compiler before launch.)

Nope.  i9-10900X has AVX-512, but  i9-10900K doesn't.

Intel really has trashed any meaning to what an i3, i5, i7 or i9 means. They need to either clean up or giveup those names.

It's designed for very wide vector processing, not for the pointer chasing in shitty javascript code which the majority of servers require nowadays. Now x86 isn't specifically designed for that either, but it's a nice middle of the road architecture and apart from Apple's chips ARM can't compete there.

The A64FX is specifically an HPC chip, and is much more like a Xeon Phi than a Xeon. It requires HBM2 memory, and other exotic stuff, that aren't going to be a good fit for high volume products. Maybe Fujitsu will produce more broadly applicable derivatives, but the A64FX looks like its only going to fit one product type.

Do not buy anything now. New ryzens coming out very soon.

But use case is important. I can think of better choices than all of them for all workloads.

Single thread is the only reason to run intel and you pay through the nose for that. Multiple thread Intel is dead on cost/compute/power consumption. Single thread may be ending with AMD zen3.

Even ARM stuff (preview data centre/compute) I’ve played with is fairly close to Xeon Gold SKUs and has better core scalability. Intel are quite frankly fucked there.

Userbenchmark is a joke, especially the last revision of how score is calculated. You literally can get i3 with higher scores than i9, not to say 8+ core Ryzen.
Unknown Owner and Team

Last proof of UserBenchmark’s lowest credibility is a mysterious unidentified ownership. Mystically, they don’t even possess specific team to represent them in internet to explain why things went wrong with them. In About page you won’t even find their names or corporate structure.

Ryzen 9 3800XT vs. i7-10700K vs. i9-10900K.

What do you think?

Do you mean 'Ryzen 9 3800XT' (as above) or 'Ryzen 9 3900XT' as mentioned in the poll? 

[olkipukki]

Do not buy anything now. New ryzens coming out very soon.

When these due? Doubt we will see early than Nov/Dec, recently we have XT Zen2 updates.

If OP cannot wait, perhaps save money on CPU now, and spend $$$ on a proper MB and memory that gives confidence in upcoming Zen3 CPUs later.

Also, SSD must if HDD still in a place.

As per OP's software list, I think Vegas Pro and some Adobe will utilise many cores, everything else still depends on a single-thread...
So, cheaper 3600X(T) beats to the dust i7-5820K with significant performance improvement.

[bd139]

Yep I’m running a 3600X at the moment on a B550 board. Drop zen3 in later and done. I did have a 3700X but due to some hardware shuffling I worked out 3600X had better ROI.

Another thing with intel is the longevity of the socket and board combo isn’t good.

Sure, once Fujitsu will start pricing A64FX in Zimbabwean dollars instead of US, everybody can afford these then

I listed most of my uses above. The 4000 series sounds interesting, but the 3900XT is already overpriced. I'm not spending more than $500 on the CPU. If they release it at the same price, sure I'd get it instead if I go that way.

[bd139]

Yeah forget the XT suffix. Not worth it. They seem to be premium selected/tested variants. Next gen is where it’s at.

If you think userbenchmark is a joke, do you have an alternative comparison site? I don't care about their opinion articles. I look at the statistics based on computers that were actually tested. In many cases, the AMD chips score higher in some sections, even if their overall score is lower.

The lack of team identity doesn't prove anything. The absence of proof isn't proof.

Their scores also point out that there's not such an amazing improvement going from the i5 10600K to the i9 10900K, so they shit on Intel too. They also link to methods to test the scores for yourself and compare to their ratings. It seems less biased to me than any other site, especially any social media outlets (this one included). I could be wrong, they could be assholes with an agenda, it just doesn't seem like it.
