I always read techpowerup first and it's almost entirely because of their graphs. Having nice neat charts of performance, performance/W, and performance/$ is something everyone should do.

It really didn't. I remember talking to a friend back then and betting ARM would become the next big architecture, even on the desktop, but I never saw the demise of x86, it's just too deeply embedded. It's.. kind of come true. At least ARM is far more successful than Itanium.

Explicitly parallel instruction computing design for CPUs just turned out to be a pretty lovely and unworkable solution and would have sucked even without x86 momentum. ARM on the other hand is inherently better but nowhere near enough to overcome said momentum.

That's a hell of a build and good overclocking numbers, will probably do something similar with Threadripper 2 and Big Volta sans SLI.

I have a question regarding Threadripper. Looking at Puget System's benchmarks of Adobe and CAD suites, Intel's similarly priced 7900X typically matches or keeps up with the 1950X in multithreaded tasks but completely slaughters it when tasks are poorly threaded. Unfortunately, there isn't much to compare with as most reviewers don;t go much further then use Cinebench, don't test professional programs or don't really go into detail what they're actually testing.

Assuming Puget Systems' benchmarks are accurate, is there an actual use case for Threadripper if I don't need the ECC memory support or 64 PCIe lanes,

The 1950X beats the 7900X by a pretty good margin in tasks that scale really well with more cores, it all depends on what tasks and what software you're going to be using.

I thought the majority of games running 4k on consoles were all running some kind of rendering trucks like checker board. To get the visual quality they do at 1080p in 4k, I doubt any consoles could do legitimate native 4k. The 1070 barely does 30 fps in Ghost Recon Wildlands and less then 30 in Deus Ex, surprisingly gets ~50 fps in BF1.

Console games can be optimized a lot better than PC games since you're always gonna be running one set of hardware, it would probably be better to use a really well optimized game like DOOM as a point of comparison.

Perhaps not as outright awful as RAM but SSD prices have increased per GB as well. And innovation in terms of drive size has utterly stagnated too. Where the hell are our 4TB drives for ~$800?

Innovation hasn't stagnated it's just the supply shortage keeping prices high which makes higher capacities make less sense, things should be better by 2019 sometime when more production capacity is coming online.

I can't be the only one who wants to see a workstation-class ARM chip, right? Will ARM always be relegated to low power implementations?

No I've really wanted a windows ARM laptop or desktop for a while, I can't even really articulate why I just want one. Maybe it's because I've enjoyed tinkering around with ARM linux SBCs for the past few years.

FaustianQ posted:

Isn't x86 vs ARM more about whether the stronger x86 cores will lose out to ARMs ability to just leverage a hell of a lot more cores for a given wattage?

Well current ARM designs are mostly low-power cores designed for mobile, if you wanted to compete with x86 you'd design an ARM core with a higher TDP. The big question is whether or not ARM offers much of a performance/watt advantage over x86 when scaled up to the level of performance needed for a laptop or desktop.

Rastor posted:

That's the best kind of correct, but the practical effect of doubling transistor count was doubling performance.

The world of processors now lines up with the world of batteries: single digit percent gains instead of 200% gains


The reason CPU performance has stalled isn't because transistor counts are stalled, as Subjunctive pointed out other areas like GPUs are still seeing big gains every generation. If you could just keep adding more cores like you can with a GPU we'd still be seeing big gains, but that approach doesn't work for CPUs because you need to balance single and multi-threaded performance. CPU performance gains have stalled because clock speed improvements have stalled and IPC gains are not even close to being linear with increased transistor counts of the individual cores. Basically it comes down to the fact that further increases in single-threaded IPC at this point are really difficult.

Yeah the Apple A12 went with the crazy wide and massive caches approach on the same process and I would assume that Zen 2 would do something like that as well since rumors are not pointing to much in the way of clock speed bumps, that's a guess though. I have not heard any specific rumors about the Zen 2 uarch other than that it will have wider AVX.

Or that the price difference isn't worth it for what frequently are unnoticeable performance differences outside of synth benches.

Yeah when you include the cost of a CPU cooler it's almost double going from a Ryzen 2600 to a 9600k or a Ryzen 2700X to a 9900k, I wouldn't go for that unless I really wanted 120Hz+ gaming or just had a lot of expendable income.

Even with an i5-8400 you're looking at 5% extra 1080p gaming performance for over $100 more cost vs a R5 2600.

My reason for thinking it's fake is that the photo was obviously of a high resolution monitor, at least 1440p and possibly 4k. I have never seen a >1080p monitor at any accounting, sales, or supply chain worker's desk. Hell, most of them still use 22" 1600x900 Dells.

I knew a lady working in supply chain who would have like 100 windows open on her 13" laptop screen until she would get out of RAM errors, a couple nice monitors probably would have doubled her productivity since she would spend like 2 minutes hunting for the desired window.

Yeah things definitely are changing, just like 3-4 years ago people here were still recommending dual cores for some budget gamers and now 4/4 CPUs are starting to have issues in some games. There was definitely no concern from most people at the time I got my 6600k that the lack of hyperthreading would ever limit gaming performance, turns out that thinking was wrong.

Laziness also isn't the issue when talking about programming either. Most of those guys are getting worked pretty hard, to the point of premature burn out sometimes. Its almost always either comes down to development budget or market support when talking about taking advantage of hardware features like more CPU cores or even other stuff like more system RAM and SSD's.

Yeah quad cores were the norm for a full decade and taking advantage of a lot of CPU cores is difficult, why put in the effort for something that very few people have? Only in the past couple years has this made sense and we have seen some change.

If they truly can just swap that 3rd chiplet between another 8core cpu chiplet or a GPU chiplet, that is really fuckin cool. The theoretical 16core AM4 design would be wild, but I can't help but feel it would be extremely memory bandwidth constrained with just a dual channel bus?

I thought that too but it was pointed out to me that Rome has that ratio of memory channels to cores (64 cores, 8 channels) and if it's not a problem on servers it certainly wouldn't be an issue on desktop. Keep in mind that Zen 2 has massive caches which will help out a bit with bandwidth requirements.
