Get a 9820x or 9900x?

[SharkGTX]

Maybe I have to set -20 offset for all AVX and get 5.4))))))))))))))))))))

I really want to like the 9900k but I cant, 16 pcie lanes and only 2 memory channels is kinda a joke. If I was purely a gamer I would probably get it. 

Makes sence if you need the pcie lanes and memory channels. The 9820x is a lower bin of the 9900x and has less Cache which may or may not matter but is much cheaper, the 9920x and 9900x are the price per core which would mean a better value if pared with the same cpu.

ONLY 1.415v? Air can handle it?! 1.415v ?!!?!?

yeah, easily, no avx though

hmm... so I will set -20 too)

I run 4.7ghz and avx offset of 1 daily though, i use my system for gaming and most games i play require avx. And i wouldn't run 1.415V unless my temps were below 65C.

Games require AVX?! for what? You can turn off avx512 and get a big offset to standart avx. And have a good temps

I usually play overwatch and forza horizon 4 and they both use avx2. (8700k doesnt have avx512 btw)

Unless you need 128GB of ram the memory channels is not a problem, and unless you need to use 4+ GPUs then the lanes are enough since the chipset adds more on top of the 16.

 

The 9900K will perform better than both of those CPUs, and be cheaper.

Those two CPUs are a two generation old architecture.

[SharkGTX]

Ah... ok) I upgraded from 990X Exteme Edition @ 5.0Ghz (bought it in 2011) to 9900X

9900K better than 9900X on equal frequency?!)))  funny

I want to see how 9900K 5.2Ghz will be better than my 9900X 5.2Ghz (1.35v) with SLI

Just because they both start with a 9 does not mean that they are both the same architecture.

The 9900X is a two generation old architecture.

A 9900k wont out preform a 9900X in muti-threaded work loads unless its like 4ghz vs 5ghz, then it would. Having 4 memory channels also gives theoretically double the memory bandwidth which can help in some work loads.

I'm just going to leave this here so it does not get mistaken with something like photoshops requirements.

Skylake and Coffee lake are the same architecture. Coffee lake is just a refinement of kaby lake which is a refinment of skylake.

If you are going to go HEDT (x299) i would recommend going with a 9920x or 9940x for your workload because seeing how much it benefits from high core count, it would have a better value then getting a 9900K or a 9900X.

Yeah I agree but my wallet does not haha. I was hoping I could hold myself to the 9820 or 9900 and toss in some more ram and/or hard drives to compensate for my sadness.

I don't blame you, they are VERY expensive cpus. Out of those 2 the 9820X is probably the better option because of its superior value.

Skylake is the same architecture the 6700K had.
Go take a look at benchmarks of that against a coffee lake CPU, you might learn something new.

The single thread performance difference can definitely make up for just two less cores.

Multithreaded workload performance depends on core performance as well as number of cores, not just how many cores you have.

Skylake has a 2-3% worse IPC then Coffee Lake.

So it seems dell should start plopping 9900k's into their servers

I'm not questioning wether or not you have 5.1GHz, but if you really want to test stability run y-cruncher to at least 1 billion digits. 

Note y-cruncher will use AVX-512 if supported by CPU. Just checked, I'm still record holder for 6 core CPU on hwbot.

It be funny if it wasn't true... just found out yesterday my EQ6 didn't survive winter outdoors.

Although I have used it a lot in the past, I never figured out what CPU it really likes, what instruction sets it can make use of, how does it scale? Actually, I think I never even hit the CPU bottleneck as I often had my raw data on HD and that was the bottleneck. That was from before SSDs were so affordable...

For scenarios that are not affected by L3 cache or ram bandwidth, or use any new instructions added since original Skylake, I've found zero practical difference in execution from Skylake, Skylake-X and Coffee Lake after normalising for cores/clock. Didn't own Kaby Lake until recently, and I doubt that's going to be any different.

Ah very nice, for awhile I was 4th with my 5820k but I'm who knows how far down the list now. 

 

That sucks about your EQ6, my cem60 is not dead but I have been having lots of issues with it lately. Planning on upgrading to a astro-physics mach2 in the next year or so if I dont spend too much on this pc upgrade,. 

 

And yeah, a majority of it is hard drive limited, I try to remember to move my data onto a ssd before I process it. The main thing I do that tends to take forever and makes the cpu sweat is deconvolution.
