Wow. AMD has really pulled through on this one. They are really giving Intel a run for their money. This is going to be great for consumers. What is interesting is the HUGE jump in multi-threaded performance on AMD. Very interesting.

But it's still losing in every web and office single threaded benchmark. EDIT: compared to 7700k that costs about the same

By ~15% compared to >160% for Bulldozer.

And this is day zero before any applications have been optimized for the new microarchitecture, compared with Core which everything has been targeting for more than a decade.

They did good.

> ... this means that the base memory controller in the silicon should be able to support ECC. We know that it is disabled for the consumer parts, but nothing has been said regarding the Pro parts. ECC should be a standard feature. If you don't want it you don't have to use it but to disable simply for market segmentation is lame.

Anandtech is wrong and ECC is not disabled at all. For example all ASRock AM4 boards support ECC memory.

Is that buffered ECC or unbuffured ECC? Because last time I checked, my AM3 board had support only for unbuffured, which is really hard to find and I just didn't bother.

Considering previous AMD chips could use ECC I hope it's true this time as well. AMD's CEO Dr. Lisa Su has an AMA later today, we should probably ask her: https://www.reddit.com/r/Amd/comments/5vl431/its_happening_a...

Might as well ask her about the possibility of coreboot if we are at it.

But it wins in every case where performance truly matters: multi-threaded calculations, archiving, encoding. You know, the things that actually do take up time.

Do you really care if your webpage renders for half a second longer?

Does anyone has a reddit account ? And know how AMA's work ? I'd love to get some input here. Or at least show we care.

Edit: Account made, instructions received. If all goes well I should be asking later today.

I don't think spending time and effort to optimize code for Ryzen will be time well spent.

Would you do it if you had the choice between that or adding new money making features/fixing bugs?

Do they ever do compiler speed tests or boot speed tests? Which of the existing ones would be most similar?

Boot speed in my experience is mostly i/o bound so I doubt it makes a significant difference over a similar Intel chip. Is boot performance still an issue nowadays anyway? Since I've switched to SSDs all my computers boot up in a few seconds (Linux or Windows). And if you hibernate instead of shutting down it's even faster. Compiler tests sound more interesting to me, I'm looking forward to those benchmarks.

I'm interested in boot just for curiosity's sake. With the new PCIe SSDs, I wonder if CPU may actually be the bottleneck.

games you say? It's up to 30% slower here https://www.pcper.com/reviews/Processors/AMD-Ryzen-7-1800X-R...

It's also up to 30% faster. That's how variance works.

Well yeah but will you buy an alternate CPU that might be faster or might be slower in some games, or will you buy standard Intel, for which every game was definitely tested and will run with standard performance?
