Why does Tom's Hardware stopped using the HPC benchmark? It was the most interesting measurement for me that work daily with finite differences and finite elements. Can you return to that?

Seems to me the best of both worlds continue to be Intel's 7900x which sells for $699 at microcenter. You get great gaming performance, and great multithreaded performance, and it's not 12-1800 bucks as some of these mega-threaded cards are.

Despite all the fan-fare, it seems the 7980xe actually remains the best processor when overclocked overall.

Lastly for gaming, it's still 8700K or 8086 as best, with the 2700x from AMD being the best when you factor gaming and some multi-threaded stuff, while being very competitive price wise.
 
Very surprising performance from the 2950x. Almost enough to consider parting ways with my 1950x. Maybe when the pricing comes down some from the 2950x in a few months I will consider.

The 2990wx on the other hand is a slight let down. Too bad they could not get the scaling down between the dies like they did with Threadripper 1. But I have read that was going to be an issue. Maybe AMD did not want the 2990wx to cannibalize their Epyc market.

With that being said, the 2990wx is still a modern marvel of technology, even more so when you consider the price. Only couple of years ago a CPU with less than a third of the cores cost just as much.

Competition sure is grand!

Looks like Intel has an opportunity to bite AMD when they release their 28-core processor. I have a threadripper 2/x399 system but if I upgrade to the 2990wx, I will also upgrade the motherboard and the power supply as well. I think I may wait until the Intel 28 core comes out and see what kind of performance it delivers as I too notice running custom AI apps on the threadripper is barely faster than my old x99/6850 motherboard overclocked @ 4.3Ghz. I want max performance if I am going to pay over $1800 for the flagship which means core wars is just starting...

MOD EDIT: watch your profanity

Seem to me that you are mistaking best of both work with jack of all trade. No one who takes rendering seriously would want to sacrifice the performance for gaming. For that price, they may as well grab a 1950X. Sure you lose in gaming, but gain a huge jump in rendering. Also, I don't know about Microcenterbut it's still 1k on Amazon while 1950X is $850. 7900X is like a really really bad choice lol.

I'm a bit disappointed again with Toms - why the Intel parts are overclocked where the AMD only on PBO and why this benchmark starts with gaming?!? Is this some kind of a joke or it's intel sponsored article?

not sure where the guylook when said intel is the best of both world gaming and multithreaded work, is he drunk while reading graph or just jump to comment stright

dont just look 2990wx,, the TR 2950X is best of all around CPU, if you want compare price to performance, in gaming 2950x is more or less equal 8700k in minimum FPS and only lose 3 to 10 FPS Average FPS,, in Multithreaded work 2950x blow anything in that price range including 7900x,, read again the article
 
The main thing I am noticing is that the actual benchmarking suites is becoming obsolete for these kind of CPUs.

One thing for sure is the next generation TR on 7nm will really help the 32 cores setup since it will probably use only a single Infinity Fabric Link and direct memory access, but I understand how much more expensive that CPU would have been and not really for that much more performances after all in what the intended field of work is.
 


In most cases, PBO will have less than 1% difference in performance than overclocking the CPU to 4.15. They provided Intel overclock information because they already had those OCs from previous reviews. Just like they showed the OCs from 1st gen Threadripper parts.

It takes a long time to conduct a thorough review, let alone 2 products and it is not like they have had this chip for a month. It probably came in last week when the unboxing videos were released. Then there was also the part where they said that they would have a more in depth article about overclocking performance.

From page 9:
The Ryzen line-up dominates the multi-core Cinebench and POV-Ray tests, but the 2990WX only provides a 35% speed over the 2950X in the POV-Ray benchmark. In light of its 100% increase in cores, that doesn’t represent the best scaling performance. We see better scaling from the 2990WX in the Cinebench test with a 66% performance improvement.
For POV-Ray lower scores (times) are better. That means that a 100% core increase should theoretically reduce (improve) time by 50%. If we look at the actual time reduction of 35%, we get 0.35/0.5 = 70% of max theoretical scaling. In Cinebench, where higher scores are better, we would expect a 100% improvement in score but only get 66%, meaning we only get 66% of max theoretical scaling. The scaling in POV-Ray is actually slightly better than in Cinebench.

Please stop the autoplay videos on this site. Would you like if someone shoved **** in your face repeatedly?

Man, I've never met anybody who uses Cinebench, nor do I have any idea what it does... But I bet whoever makes that software is super psyched flagship processors are being designed to be amazing at running it, for some reason.

So where's this 2950x review that is supposed to compare the different modes it runs in?
 
I can't believe someone managed to say that a 7th gen quad core is better than any of these... Now though, the 32-core sees to much diminishing return to really be useful, but the 2950 really is the sweet spot for this platform.

Probably because manual overclocking on Zen+ based Ryzen CPUs is pointless unless all your important applications are heavily threaded.

Since a manual overclock and voltages are decided on a fully threaded workload, it results in comparatively bad performance - lower than stock - in lightly threaded applications (on Zen+ with its advanced boosting). The Threadripper processors have such a high number of cores that the performance deficit is exacerbated.

Instead of overclocking manually, on Zen+ you should instead enable PBO, then lower the CPU voltage using offset. This lowers temperatures and power use, allowing the CPU to boost even higher.
