ECC is a feel good feature, but is mostly useless. Memory either is corrupted (which can be detected by running MemTest) or it works perfectly fine without ECC. I have over 50 10+ year old Itanium servers with 192GB ECC RAM each, there are 2 ECC errors logged total, while running 24/7.

To word your statement differently: without ECC, your memory either works fine or is corrupted. But you don't know which one it is, until you run memtest. How often do you do that? Personal anecdote: Upgraded RAM in my PC, ran memtest, everything fine. A year later, I need to move and so I consolidate all my data on a big hard disk. As the disk is new, I run some verification and notice some non-matching checksums. L…

What many don't realize is that ECC is a bit like paying for insurance just built in to hardware, most likely you won't need it, but if you can run ECC sticks other than cost there is no reason not to.

You're right about the AVX2 part. If that's important to you. Otherwise I'd have to disagree, waiting all those years and going to a quadcore is sad. This is a monumental shift to see $330 8C/16T chips start to be mainstream. I also hate that Intel went with that cheap TIM that requires delidding. You're in a tough spot given the focus on AVX2 IMO. My thoughts on Ryzen in general though is that the base 1700 is the c…

Ultimately, the number of cores doesn't mean anything by itself, it's the aggregate performance that matters. We'd all happily take a 16 Ghz single core CPU over a 4 Ghz quad core any day, if such a thing was possible. It's true that I'm in a very niche spot in that most of my workloads are vectorization-heavy, but I don't think it's quite as niche as people think. If you look at the benchmarks, quite a few workloads…

Your info is a little outdated, checkout Digital Foundry's videos on i5s vs i7s in current gen games. The day of the quadcore being a great choice for gaming is already over if you play the "wrong" games. No longer a slamdunk recommendation. At this point I'd recommend gamers step up to the i7 or R7. Anything "will work", people are using G4560s. I'm suggesting what's ideal at this point in time.

The aggregate performance of an 8C/16T machine from any vendor is astonishing, of course.

Condescension is warranted towards those who assume they know anything about one's needs.

No it isn't you fuck twat.

Looks great, coup successful by AMD. Takeaways after a few of the reviews on this list[0][1]: - If you're buying a desktop quadcore processor in 2017, you're doing it wrong. May as well buy a laptop. - Kabylake sucks as a workstation chip but is ok for gaming if your PC is solely a glorified Xbox. - Vast majority (90%+) of gaming rigs are GPU-bound. Think very carefully before giving up 8 cores and 16 threads at the…

>> If you're buying a desktop quadcore processor in 2017, you're doing it wrong. May as well buy a laptop. Not true, IDEs, web browsers, office tools need single core performance and not 4+ cores. A laptop is more expensive, will make more noise when loaded, is harder to upgrade, is less customizable, has less ports, is more expensive to expand (ThunderBolt devices are not cheap at all). What are you talking about? >…

I don't know if it was attempted, but you can turn down the condescension.

Condescension is warranted towards those who assume they know anything about one's needs.

Your comment broke the HN guidelines. The civility rule applies here regardless of what someone else assumed, so please take care to abide by it. Even if you don't feel you owe better to the other person, you owe it to the community.

Did anyone else find the "Simultaneous MultiThreading (SMT)" section of the article to be long on hand-waving and short on detail? It seems like all the actual information there is conveyed in the diagram, the text is full of nearly content-free sentences like "With each thread, AMD performs internal analysis on the data stream for each to see which thread has algorithmic priority.".

What exactly do I owe to a community that refuses to support the people I send to it? You consistently refuse to fix your broken braille support for denoting italics. Can you or sctb provide an answer to why this blatant discrimination is occurring? I believe the community deserves a public answer.

I'd also like to point out that studies show that people read the words of others in their own inner voice - in other words, the poster saying I was being condescending was likely being the condescending one.

You said 8K video with thousands of streams. That thing just looks like a normal video chat app that any modern CPU should have no problems with.

No, you need GPU acceleration because you can open as many videos as you can fit on your screen. I have quad 4K monitors for an 8K setup. I can have a couple thousand video streams at once. Let me see ANY CPU that does that.

just curious what are you doing with all those video streams?
