I remember cyrix being later in the game with its 686/166 Mhz proc which did wonders.

Cyrix had a 486.

and 586 and 686: https://en.wikipedia.org/wiki/Cyrix_6x86 They used a Performance Rating, so the "PR166" wasn't actually running at 166 MHz but 133 MHz. The performance rating was meant to show that it was "equivalent to a 166 MHz Pentium".

The 65W versions should be trivial to cool silently, a $40 heatsink with a single low speed 12cm fan (500~600 rpm) does the job well with my CPUs. For a 95W TDP you might need to spend a little more (like on those big Noctua heatsinks with 14cm fans), but silent air-cooling is definitely possible. (Water is always trickier, AIO kits will typically be a little noisier due to the pump).

At these TDPs, fully passive cooling is an option: http://www.silentpcreview.com/NoFan_CR-95C_Copper

That's huge :)

In a smaller HTPC it can make sense to go passive but for an 8-core desktop workstation I'm not convinced it's worth the trouble. Your PSU and GPU will likely have fans, also with a PCIe SSD it's better to have some airflow.

AFAIK the Ryzen 1700 (TDP 65W) is supposed to come with a "Wraith" cooler from AMD and those new ones are apparently better than their shitty older counterparts from the Vishera days (I had one and I'm glad I switched to a near silent Arctic cooler).

Same here, the Artic Cooler was 20$ and the difference is dramatic. Cooler temps all around and near silent at modest loads, where the stock cooler was annoyingly loud.

More importantly for some, it's a 95W AMD part vs a 140W Intel part. If the power delta stays the same even for mainstream parts, does this mean AMD will become a good quiet option too? By quiet I mean "I can't hear it at night" not "I can't hear it over the music". Edit: Also, I think data centers these days are limited in density by power delivery and cooling. Even a 25W delta adds up when you're talking about thou…

TDP is a bit tricky to compare in this situation. The TDP of Intels HEDT chips is dictated by their 256-bit wide AVX units which drive power consumption through the roof when fully loaded, and the chips don't get nearly as hot when AVX isn't being used. Ryzen doesn't have this edge case because it sticks with 128-bit SIMD units and runs AVX instructions over two clock cycles.

I expect the "140W" Intel part will have closer power consumption to Ryzen in non-AVX loads, and outperform Ryzen in AVX loads while using more power.

Wow... I really hope this is true and that it's a sign that AMD have their mojo back. Partly because I have a sentimental favoritism towards AMD, and partly because Intel (and Nvidia) need competition.

AMD giving competition to NVidia would require them to actually put some effort into their drivers to get tolerable performance and a list of bugs that isn't as long as my arm.

Ryzen leaks conspicuously don't mention gaming or the i7-7700K. AMD may win in a very small market yet lose the mainstream.

Gaming performance is irrelevant for top CPUs, the difference appears only in low resolutions and old games.

The "games don't use CPU" line is only really true for multiplatform games that must also run on the low performance PS4/XBox One AMD Jaguar CPUs.

If we look at PC exclusives [1] then we can see that these are extremely CPU-hungry games. This hunger only goes up if we want to achieve a framerate higher than 60, say going for 144.

I personally have an i7 @ 3.8 GHz with GTX 1060 and none of these games can hold a stable 1080p @ 144 Hz. What's more, I've benchmarked the effect of changing GPU/CPU and increased CPU power increases FPS far more than increased GPU.

I upgraded from Radeon R270X to GTX 1060. In multiplatform games this is a huge leap. Battlefield 4 (1080p Ultra) goes from 43.1 to 94.8 [2], a whopping +120% increase. While in Dota 2 (1080p Ultra) that only netted me a +11% gain. Then when I overclocked my i7 from 2.8 GHz to 3.8 GHz I got a +23% increase.

This question comes up constantly. Anybody doing anything with more than 16GB, especially data science (think all the R and Python people, all scientists), anybody running a memory cached data store (all server side people on mongo, redis, etc), and anybody doing finance or engineering, wants ECC. Basically anybody doing anything where data persistence is important, and/or where even the slightest chance of silent co…

> Anybody doing anything with more than 16GB, especially data science (think all the R and Python people, all scientists) Not sure I agree. Most science datasets (both from simulations and experiments) are sufficiently noisy that if your scientific end results and conclusions change as a result of even thousands of bitflips in your 16 GB of data, you're Doing It Wrong and your article isn't worth the paper it's print…

As soon as you are putting a noisy dataset through multiple iterative algos, though, if a bit error hits the control flow code or data structure delimiters, you face the possibility of massive silent, propogating corruption. Imagine your hash table getting a bit error in it (all R lists and Python dicts use them), or an incorrect branch in your code. Admittedly the risk is ultra low, but you have enough problems to worry about to have, in addition, a niggling sensation of RAM-risk as you work.

More generally, it's not unreasonable to say that our entire computing paradigm rests on accurate RAM. Above 16GB, the risks just become too big for anybody doing serious work, and not just messing around with prototypes.

Especially since AMD's APUs' integrated graphics have stayed superior to Intel's.

Is it still true? http://www.hardwarezone.com.sg/feature-integrated-graphics-f...

I think I've seen news about intel negotiating with AMD to integrate their GPU design in place of intel iGPU/IRIS.

Is AMD still publishing the real power envelope of their chips while Intel is publishing "normal" power consumption?

It's now possible to build very high-performance rigs that run completely silently. Palit offer a fanless 1050ti; Asus Strix 1060/70/80 cards will run with the fans stopped under light loads. Fanless 500w PSUs are readily available, which will happily power an eight core machine with a GTX 1080. The brilliant Silverstone FT03 case uses a chimney-like vertical design that can create significant airflow through pure convection.

Passive cooling isn't for everyone, but the remarkable efficiency of modern components has made it a perfectly feasible option even for high performance workstations. You can choose whatever level of noise you prefer, from extremely quiet to dead silent.
