You could pick a Ryzen with "G", like the Ryzen 5 2400G, though... They have an integrated GPU.

I know of the G series and I know why they are usually a GEN behind specially given the quality of discrete graphics AMD has and they need to sale. But for work, for just productivity a lot of the savings washes up with the GPU. It used to be that you get super lowend graphics card for those workload but these days almost the lowest price GPU is ~90.

$39:

Hardly the latest technology but you can plug a monitor into it.

Is there any clarity on how much RAM the 3900X supports? Presumably can do 4x32GB, which would make for a great little bioinformatics workstation. Am very excited with this chip and Windows bringing the full Linux kernel - can do everything I want at home with just one fairly cheap PC and no dual booting. Good times!

I'm really looking forward to this. But one issue with current AMD cpu is that you have to buy a desktop GPU even when you are not doing any kind of gaming and such. I know intel iGPU haven't been terribly good but for work they are good enough and is one less part and cheaper to boot. For same performance a Ryzen 3rd gen + gpu might still be cheaper but the price advantage gets reduced. I haven't really seen that me…

AMD just aren't selling many CPUs to business desktop system integrators, partly due to dubious tactics by Intel to keep them out of the market. If you sell most of your CPUs to enthusiasts, it just doesn't make sense to squander die area on a crappy iGPU. Gamers obviously want a fast GPU, but so do most creative professionals - Photoshop is heavily GPU accelerated, as is Premiere and Resolve, not to mention essentially all 3D modelling and CAD packages. Scientific computing is also rapidly moving towards the GPU. GPU performance has a surprisingly large impact on day-to-day responsiveness, because all the major browsers use GPU compositing.

The market for fast chips with crappy iGPUs just isn't as big as it used to be, nor is it particularly accessible to AMD. The Athlon and Ryzen APUs make a great deal of sense for the current market, offering a good balance of performance between CPU and GPU. I expect to see 6 and 8 core Ryzen chips with Vega GPU cores as part of the Ryzen 3000 generation, which will further close the gap.

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?

Frightening lack of press around this. Basically all of Intel's and AMD's lineups are centered around high thread count right now. Completely useless if I can't reasonably enable SMT.

AMD's chips apparently don't have the security vulnerabilities that make SMT unsafe to enable on Intel chips - they released a white paper explaining why MDS etc aren't possible and what exactly the boundaries are on their chips: https://www.amd.com/system/files/documents/security-whitepap... It just didn't get a huge amount of press coverage.

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...

assuming computers here means CPUs, honestly i think 70% of this (needing "more processing power") is just marketing and consumerism, 10% is OS bloat and the rest is probably legitimate.

i'm sure 100 JPL astrophysicists will pile in here but i've been using an AMD 3.2ghz quad core processor purchased in 2010 for software development in java, scala, clojure and now golang as a daily driver up until today. i've replaced the RAM twice, power supply once, and the video card once.

i proudly use linux so i'm not sure what the situation is like with other OSes, so i'll budget some for things like windows "growing" over the years, but it's just not necessary for me to update the processor until it dies.

It's my understanding that Navi is just GCN but tweaked with faster memory.

Yup. Just waiting on the benchmarks from independent reviewers and to see how XFR in this generation works but I’ll be getting a Ryzen 9 if everything checks out. 24 threads will be amazing for local development (microk8s, and others) when I’m not gaming and save me from having to build a separate box.

What will you be doing that will actually use 24 threads?

Develop multi-threaded scientific applications?

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.

Was it the following video by Optimum Tech? https://www.youtube.com/watch?v=pxcDeq4SQII I recently purchased an NH-U12A and can confirm it is excellent.

Linus Tech Tips recently published a video called "why you shouldn't water cool your PC"; they found that a Noctua NH-U12A ran cooler and quieter than an AIO liquid cooler.

The G-line of CPUs with integrated graphics is also interesting to me as well! As system ram gets quicker (it's my understanding that the frame buffer for these integrated GPUs comes from system ram) and nanometer tech gets better that a competent integrated GPU+CPU chip will be able to play AAA games at 1080P with some of the visuals turned up. Though the conspiracy theorist in me thinks that the console makers would never let that happen as it would mean DIY PC gamers would be able to build < 500 USD machines that could be play all the latest games.
