I just tested it. They use built-in Microsoft Sam as TTS (at least in Windows), old and awfull.
TTS in the Edge is pretty close to the bleeding edge. It's good. Both English and Russian. And Edge is still a gorgeus Chromium without recent time UI degradations and without ad- and privacy- blocker intolerant management.
Personally i have a prejudice against Firefox for subjectively poor and ugly UI and old scars from their rendering issues.
I personally use Edge almost daily for their awesome in-browser TTS and reading-mode feature. I inspire you to try it.
For general purpose Google account integration convinience grip is yet overweights their constant effort to ruin UI and extensions. Also Edge App Store still lacks uMatrix, but already has uBlock Origin.
Energy is not the only thing you should care about freight and human logistics.
Logistical resources of cities are scarce and it already badly affects labor market there.
Let's assume we observe a system of planets and we have a good theory to describe its behavior.
Then with better tools and more observation we found an orbit deviation. Patch it by assuming additional yet unobserved planet? Or patch it with much more sophisticated mathematics?
Here is a fresh Zen1 timings comparison from Reddit[1].
Most increase is between 3200cl14 vs 3200cl12. 12%. Difference between this two is almost purely a Latency.
Then compare 3200cl12 and 3600cl14 - 3%, marginally no increase. Almost no difference in latency, only throughput and IF.
Past 3200 RAM throughput and inter-core-communication (IF) has very little influence for Zen1 gaming. For Zen2 this scenario would differ in some ways but not too much.
I will distill your post to: most user builds are bad balanced to begin with and they wont see a difference and would had a better price / more cores. Valid point, i agree with it. Still could be argued about a need for a better memory for Ryzen. This equalizes total build cost and you need to be informed about this platform trait beforehand, which will results in even worse average build balance. Imagine prebuilt PCs from wallmart with 2400 leftovers.
But my point is more about advanced user builds and press benchmarks.
[0] - 2400 cl16. It's much worse than 3600 cl16, used in referenced Ryzen 3000 test. It would be interesting to see how Ryzen would perform with it. May be zen2 comparison with 2400 vs 3400 (3600 is very rarely achievable there as IMC trait of the platform) would be a good illustration.
[1] - 3200 C16. But it performs way bellow expectations. Modern Intel chip should have ~55ns with it. With 3600 cl16 intel will have ~40ns.
Few games will suffer greatly from it, but there are several titles with RAM bottlenecks, like PUBG and FarCry.
Anyway, AMD has a much better price/performance offer than Intel. For general puprose Intel is totaly anihilated, but for the games they are still more than competitive.
