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.

Just as an FYI for anyone looking for cheap basic display adapters, you can basically get an infinite supply of refurbed/pulled Quadro NVS 295 cards on eBay for $5-10.

Takes guts to stick with that core count and at least you get to enjoy the full 70MB of cache. Good thing Blender and Cinebench all fits inside that, not sure you can ever say the same for productivity workloads. I guess AM4 also means no real improvements on the PCIe lane count: Would love to see real and IF switches to give a bit of flexibility and what they plan for a new Threadripper.

I am quite surprised that they're launching a consumer CPU with 70MB of cache! When most CPUs have ~8MB, I don't think there's ever been such a huge CPU cache jump in history.

Those duel CCXs means the 16 core Ryzen could be ready for release (that's what I have my eye on!). It's funny, going from 12 to 16 cores is basically the i7 6700k in my desktop.

Plus, it's great that Intel is being aggressive by releasing the 9900KS (which is a pretty good GPU for gamers). It's been a while since we've seen any real competition between AMD & Intel.

$39: https://www.newegg.com/visiontek-radeon-5450-900860/p/N82E16... Hardly the latest technology but you can plug a monitor into it.

No DisplayPort and it almost certainly doesn’t support 4k at 60Hz, both of which the Intel chipset supports and both of which I’d consider essential for high-end productivity use these days.

I started getting crashes recently and so I did a memtest64 run. A couple of errors... but only in one of the tests. I backed the memory clocks down from 3200 (which it's supposed to be rated for) to 3000 and it passed with no errors.

Are you running correct voltage for 3200? Double check the spec! (Got bitten by this).

What are you talking about? you can get RX550s that are passive or even one of the rare RX560s which are passively cooled

I can't find a single passively cooled RX550, albeit some are passive up to a certain temperature, which is likely acceptable for the usecase assuming it works as advertised.

worst case scenario you can always buy an aftermarket passive cooler and swap the cooler yourself

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!

Are 32GB sticks of fast registered DDR4 still absurdly expensive?

Still not cheap - $200 for DDR4-2666 up to $350+ for DDR-3200 from what I can see on Newegg

>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. 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…

If you sell most of your CPUs to enthusiasts, it just doesn't make sense to squander die area on a crappy iGPU. I'm a developer, and I want fast build times. I don't need a dedicated GPU for that. Right now I'm squandering money and power on a dedicated GPU which is probab…

You can buy a used GPU for well under $100. Now you can drive multiple 4k screens for that HiDPI terminal goodness and stop choking your CPU's memory bandwidth :)

Still a better deal than Intel and a superior desktop experience.

My guess: standing by for a last 2019 or 2020 refresh. AMD simply doesn't have to play their full hand right now to be competitive. Going to 16 core on AM4 looks to be trivial on paper since they're already doing 12 core: just a matter of clock speeds and core voltage to make it happen inside of AM4 parameters.

I really expected a 16C/32T Ryzen 9 though.

My guess is that bandwidth and cooling limitations meant that 16C/32T Ryzen wouldn't have been much faster than 12C/24T. It sounds like the 12C/24T outperforms the 12C/24T Intel; if they had released the 16C/32T reviewers would compare it against an 18C/36T Intel chip, which it may not do as well against.

the problem is new TR is not on their 2019 roadmap PPT

That's too bad, it's a really neat chip line. More PCI-E lanes than a Xeon E5 without the ridiculous premium.

There are rumors that AMD is not happy with TR2's memory performance as the 4 channel memory controller is the bottleneck, they are probably looking at 8 channel memory option for TR3. ;)
