The second | 10nm process produced laptop processors that began shipping | last fall, but are still mixed in with 14nm processors that | are branded as part of the same generation. | heelix wrote: | I'm really excited with the prospect of a a fast, multi core chip | that does not throttle on a laptop.

If you have a task that doesn't | parallelize well, you can't beat intel. | | Games are traditionally single threaded and hard to | parallelize. | | However: you don't need to be the best, you just need to be at | the "agreed upon" high end for game requirements, which is the | xbox and ps4 (soon to be next gen). | | And so, if you're trying to build a "generation proof" gaming | PC in a standard sized case, the 3800X is currently your best | bet for a new build (or waiting for zen3). If you're trying to | do SFF, Intel may be a better choice. | | Regardless: AMD's competition has dropped the prices in the | "enthusiast" segment. My next build will be AMD, simply because | I don't need the best of the best, but rather, good enough. | Polylactic_acid wrote: | From what I have seen, the single threaded tasks are slightly | better on intel but even in this linked article the AMD chips | are winning slightly in single threaded. And in multi | threaded the AMD CPUs absolutely blow away intel by a huge | margin at a lower price. | ksec wrote: | >Games are traditionally single threaded and hard to | parallelize. | | It is not that the Gamers and Prosumers dont know. | | But they are willing to trade ~10% of Single Thread | Performance for Double the Core at a similar or less price | point. | | Sounds like a very reasonable decision to me. | Polylactic_acid wrote: | Also games are hardly limited by CPU at all a 10% loss in | single threaded won't be noticed at all but more cores will | make a huge difference for other tasks. | shmerl wrote: | _> Games are traditionally single threaded and hard to | parallelize._ | | That's some dinosaur games from the past. Modern games are | using all available CPU cores with something like Vulkan and | saturate GPU fully. So Intel CPUs are left in the dust with | all the cores you get from high end Ryzens. | gameswithgo wrote: | the new ryzens compile gcc things faster, even on one thread. | and you get more cores per dollar all the way up | onli wrote: | That's a bit outdated. Yes, the fastest cpu for games is | still an Intel cpu, the i9-9900K. But the distance is not | big. The 3950X is very close, the more reasonable AMD cpus - | Ryzen 7 3700X and Ryzen 5 3600 - are also close. I collect | benchmarks, comparison here [0]. When the next Ryzen | generation arrives on the desktop even that small top spot | for Intel will likely end. | | It's not only that the turbo boost of those Ryzen cpus is | high and at the same clock Intel does not have a lead | anymore. It's also that recent games are already pretty | parallelized. There is no need to wait for the next console | generation to see that effect. | | Btw, the 3800X is not a good pick. It is just a minimally | higher clocked 3700X. If you want 8 cores, get the 3700X, the | higher price of the 3800X is just a waste of your money. But | for gaming you want to stick to a Ryzen 5 3600. | | [0]: https://www.pc- | kombo.com/us/benchmark/games/cpu/compare?ids[... | blattimwind wrote: | > Games are traditionally single threaded and hard to | parallelize. | | On my 3900X I've seen even single player action titles | utilize 16+ threads with overall CPU utilization reaching | peaks of 80-90 %. | | Yes, it maybe be _hard_ to parallelize game engines, but all | major ones heavily use multiple cores. A bunch of years ago | (4-5) people would recommend an i3-K dual core for gaming, | because you could overclock it to 5+ GHz on air. That was | sufficient for many titles back then. (And these i3s would | sometimes give you higher FPS compared to the more expensive | quad-core options). But a CPU like that is far too weak for | newer titles. | | > You still can't beat intel at the high end. Both in terms | of heat and performance. If you have a task that doesn't | parallelize well, you can't beat intel. | | In terms of heat, that is, performance per Watt, Intel's high | end is quite a bit worse than AMD's. It is true however that | you can get slightly higher single-threaded performance out | of Intel's highest-end CPUs, but not because they are more | efficient (- AMD is better both perf/W and IPC-wise), but | just by raw, unadulterated clock speed, pushing them to 5+ | GHz. And that causes them to burn _a lot_ of power. | jakogut wrote: | > You still can't beat intel at the high end. Both in terms | of heat and performance. | | This sentiment is almost a year out of date. Since Zen 2 | launched, Intel has a measurable disadvantage in IPC. Intel's | single-thread performance is only partially won back with | higher clock speeds at the expense of far greater power | usage. | ckastner wrote: | I built a new workstation in December, and I like my computers | to be as quiet as possible, so I looked for a huge cooler and a | top-quality fan. | | Reading reviews of coolers and fans was just eye-opening with | regards to AMD's recent success. Most reviews proudly mentioned | some Ryzen product, and barely any mentioned Intel at all (and | most coolers are compatible with both). | | I realize that the build-your-own-PC enthusiast represents only | a minor fraction of the overall market, but seeing AMD's | reputation going from "the budget CPU" to becoming the new | Coca-Cola whereas Intel is now Pepsi, all in the span of what, | 2 years? was amazing. | | The server and laptop markets have other dynamics (a few large | buyers, instead of many individuals) and I'm not sure AMD can | compete with Intel on these dynamics, but I really wish them | success. | Symmetry wrote: | When I built my first computer the conventional wisdom was that | you wanted to use an AMD Athalon-64 processor and an NVidia | graphics card. And there we are again. | michaelyoshika wrote: | Not following closely to the CPU industry. What right steps have | AMD taken to achieve the recent success (compared with Intel)? | jayflux wrote: | They started from a new clean-sheet design. You can read about | it here: https://en.wikipedia.org/wiki/Zen_(microarchitecture) | jakogut wrote: | Intel made missteps with their 10nm process, and manufacturing | chips in house. Yields for their new process are too low for | retail demand. Additionally clock speeds are higher with the | more mature 14nm process of Kaby Lake, which is itself a more | refined version of Skylake. With low yields, manufacturing is | too expensive, and performance isn't much improved, leaving | Intel little reason to bring these new chips to market. As a | result, they've been refining and refreshing chips since | Skylake. Kaby Lake introduced a bump in core count, as a | response to AMD's release of their Zen microarchitecture. | | AMD overcame these challenges in several ways. They're fabless, | choosing to partner with semiconductor manufacturers like TSMC | rather than manufacturing chips themselves. TSMC's current 7nm | process node is one generation ahead of Intel's 14nm node, | roughly on par with Intel's 10nm node. Smaller process means | more efficient, and often more performant. | | AMD also created a new architecture using a "chiplet" design | and an interconnect (Zen), rather than the older monolithic die | used by Intel. This increases yields and simplifies | manufacturing, while making chips modular. Chiplets containing | a number of cores can be combined into a single package to | create various SKUs, targeting different market segments. | Symmetry wrote: | Excellent engineering management that has figured out a good | architecture to re-use a few designs across a number of market | segments. Years of investment previously in automated layout | that let them iterate more rapidly and migrate from fab to fab | as needed. Serious problems with an over ambitious node on the | Intel side which resulted in flailing by Intel management. | Roritharr wrote: | Hiring Jim Keller. | baybal2 wrote: | Zen architecture team lead was Mike Clark, engineering lead | Suzanne Plummer | | I am very sure that they didn't hire a man like Jim Keller | "just" to do engineering work. In Intel, he is more of a | project manager with extraordinary authority, and I believe | that was the case for him for the last 10 or so year. | | He shipped countless triple A hit products, probably more | than any other man in the industry. That experience is his | real value. | bgorman wrote: | Intel's fabs have stagnated so AMD now has access to fabs as | good or better as Intels. In addition, AMD has been iterating | on a new micro-architecture for the last few years that is | actually competitive with Intel's. From 2011-2015 AMD's | Bulldozer based micro-architectures were not competitive, and | coupled with being way behind on process nodes was a completely | uncompetitive high-end product line. | jfb wrote: | PC World is still a going concern? | uyuioi wrote: | Come on Apple.
