It is amazingly cheap (compared to the intel's 1.1K), wonder what could be the reason behind it.

They probably have something secret to counter intel in the 1k range. Probably 128 cores spread across a square-foot of silicon. Enough output that you can boil your coffee while gaming.

If your use case is to fry some meat, I believe Intel still holds the crown.

I'm expecting some new, crazy high binned, extremely expensive Intel CPU with sky-high TDP to be announced soon.

I didn’t see any word on whether the vector units are still half width. That’s still a major performance advantage for Intel.

Read that often here tonight. Is there a killer app for single core performance other than UI/UX?

In all seriousness, I've been wanting better single threaded performance for running a Minecraft server.

What kind of player count are you getting?

I have been running 4 players with one of the most taxing modpacks on a mid tier digital ocean VPS with no hitches. Not many players I guess but in case you were curious if you could use a VPS. Even when we had multiple excavators sending thousands of entities through sorting pipelines it was stil doing surprisingly well.

Isn't AIO liquid cooling still a good solution for decent overclocks without emptying your wallet for a custom loop? To my knowledge, those $40 silent air coolers perform well but still can't match a big liquid radiator.

I can't find the link but a youtuber tested various AOIs and air coolers and a Noctua air cooler did the best job cooling. Unless you like AOIs for some other reason (e.g. some people don't like all the space air coolers take), if you aren't running a custom loop you're probably wasting your money when water cooling.

Interesting. Do you have any idea as to which Noctua cooler it was? Their highest end ones run really close in price to the lower end AIOs.

Looks like that 499 will include a cooler too. Id probably not use it (liquid cooling is better imho) but an included cooler is a perk.

I wish they had a slightly cheaper option without a cooler. I already have a good air cooler from Noctua.

The Ryzen 7 3700X looks like it hits a sweet spot. 65W TDP, $330, almost as fast as a 9900k. Was originally planning to go for the Ryzen 5, but with these specs it seems silly not to go for the 3700X.

Also with CPU performance starting to taper off I think people need to also start think of their computers as longer term investments. I think the 8 core makes sense. Even my phone has 8 cores now...

Now imagine a Threadripper with the Zen2 cores, higher IPC and frequency would be certainly welcome. Have the 32 core 2990WX and it's an incredible CPU for compiling large C++ programs, running big test suites and never having to worry about running too many tasks at the same time.

A lot of AAA game studios with larger C++ codebases use Incredibuild a lot. I can imagine having something with this level of parallelism would be incredibly useful.

Isn't that what AMD GPUs are for? They'd be eating their own market share for PCs that double as frying pans/ovens!

If you're basing that comment on TDP, think again.

NVIDIA redefined TDP to their convenience, to mean something more like "averages". So their numbers can't be compared directly.

Always look at third party measurements. I'm looking forward to Navi's, while on the topic, as they've announced large improvements in power efficiency.

My question is how is their architecture doing regarding the assorted speculative execution baked-in issues and what kind of impact is there on the AMD processors compared to comparable Intel CPUs?

They are full 256 bit wide now, that's how it can claim a 2x float perf. improvement. It also doesn't have an "AVX" offset.
