Sad, 10 years of nothing from intel but single digit uplifts and increasing power. I think apple sort of proves that there is plenty of single threaded perf uplift available with the right designs (aka one not designed for a server). Even AMD traditionally trailing is easily surpassing them now too, the AMD core that is easily matching or beating them isn't even close to the best desktop part they have (and rightfull…

Yet they are still the king of single threaded performance (barely). I'm not so quick to rule out Intel, even if I have no love for them. While the M1 was extremely impressive from a power efficiency standpoint, I think the jury is far from out on whether Apple will be able to take those gains and scale them to serious computers.

They certainly are not king of single threaded performance. Both Zen 3 and Apple's M1 comfortably best Intel in single core performance, using much less power to achieve that. Intel lost the single threaded crown in mid 2020.

What an odd experience. I haven't heard of anyone having similar experiences with Ryzen, including myself. Maybe you got some unusually finicky motherboard?

It's a mini-ITX Gigabyte B450, the Aorus line. From what I found online, there were plenty of cases of incompatible RAM that would simply not boot. The "odd" thing is that this Intel system I put together ended up being the very same brand. I am regretting it now a bit because I realized that the board can only do 4k@30Hz through the HDMI port and the i9 can do 4k@60, but given that my laptop had a similar limitation…

The difference may be due to the version of the HDMI port: HDMI 1.4 can only do 4k@30Hz while HDMI 2.0 can do 4k@60Hz.

I see nothing in this review that would make me choose the Intel part over a Ryzen 5800X.

Price is the biggest factor. You can get 10 cores with Intel for cheaper than 8 with AMD, plus with Intel you get integrated graphics as well which is really important right now considering the GPU shortage. Also, Intel allows virtual GPUs for virtualization in QEMU which AMD won't do.

Ah, 11700k is 8 core, like the 5800X??

AMD needs to integrate basic gpu in its higher end CPUs. With the current gpu prices where even old low end models are selling for double it will make sense for anyone needing good desktop experience without need for a fast gpu otherwise AMD is missing a market segment.

There is no shortage on dedicated low end GPUs.

Isn't such a thing necessary as we see US presidents falling for (deep)fake media? Is there a privacy-respecting solution that you prefer?

Not sure why this is downvoted, the questions are constructive for the thread. To add a question: why is it bad if it's an optional component? Nobody's forcing you to disclose that you shot a certain picture, unless I'm misunderstanding the concept here.

When similar measure was implemented for printers, it was not only not opt-in but also a secret for quite a while: https://en.wikipedia.org/wiki/Machine_Identification_Code

The possibility of this being opt-in is so unlikely it probably not worth discussing.

Some form of GPU with modern display out is needed for some multi-monitor setups (mostly 4k), even if you don't do ML or gaming. Unfortunately there are also many motherboards out there that only support running one 4k monitor at 60 Hz even if the integrated graphics support more.

if you are going to use the GPU solely for the video (output) acceleration then you still have many options that can do that but (fortunately?) can't mine digital currency efficiently.

Don't know about that. Here in France, I've just checked Amazon for a cheap, relatively modern GPU and the offer has dried up (at least those sold by Amazon). I'm looking to run a GPU-passthrough virtual Windows on my linux PC without integrated graphics.

I bought a RX550 a year or so ago so my father could run a 4K screen. It cost around 100 euros at the time. This would be ideal for my use case, but now I can't find one. Are those even useful for mining?

On the nvidia side, all you can find is some GT 710. Not sure those can run 4K screens (didn't check). Even the GT 1030 is hard to find - a few months ago they were everywhere.

What happened? I’ve never seen a computer die during use.

Gaming performance regressions leave me a bit stunned. That's impressively bad, even for Intel. What are they going to do now, price this below the remaining Comet Lake stock and hope that Zen 3 has low availability until they have Alder Lake ready?

Are they really? AMD will make gains for sure at this rate, but TSMC can't serve the whole market. Intel owns fabs, and these rocket lake chips will sell to the mainstream just fine. I expect intel's fabs to be a big asset in these COVID times with sold out computers.

This chips really don't seem to be a good use of Intel's limited fab capacity. The CPU cores are substantially larger while offering basically no benefits other than AVX-512 support. It looks like Intel would have been better off pairing the upgraded IO and integrated graphics with their existing, smaller Skylake cores.

Ignoring both sides of the performance debate entirely, Intel found a way to increase utilization of 14nm process in a time when sector-wide demand exceeds supply. It seems very smart to use 14nm because it presents a lower opportunity cost versus getting worse yield on 10nm process node and taking capacity away from laptop chips, an area where AMD has been struggling to meet demand.

There is in the Netherlands it seems. The only one available AMD one is a RX 580 for €669, the only available Nvidia one is a €109 GT 1030. The GT 710 cards seem like a huge downgrade in terms of display options compared to my laptop’s integrated graphics.
